Electromotor protector reachs his to develop a tendency

Regulate production, sale to disobeying this, should instruct halt production, sale, confiscate illegal product and illegal income, be in 1, 5 times amerce, till cancel,do business charter. 2.

Want to confiscate the product that public proclamation washs out to using an unit, instruct close down is rectified or close a business. 3.

Still introduce the product that national explicit order washs out when the project is designed to designing a section, uniform count inferior design, the project examines and approve an unit not to grant to examine and approve, the person that violate investigates the design, duty that examines and approve personnel. 4.

Produce a business to product of each whole set, uniform must not be purchased and use wash out a product to regard form a complete set as product, form a complete set. Otherwise, press unreasonable product processing, its product must not leave factory, investigate the duty of industry leader lawfully. 3, domestic electromotor protector (electric machinery protector) state (one) hot relay is the fifties the protector of overload of electromotor of sheet metal mechanical that Russia technology development recommends first. It is had in respect of protective electromotor overload turn over the characteristic with time limit function and simple structure. But existence function is little, do not have photograph protection, ventilated to electric machinery happening not free, sweep chamber, locked-rotor, long-term overload; Start often wait for breakdown not to have protective effect. Because hot relay moves compose line and electromotor to protect a curve actually,this basically is abhorrent, lost protective action. And repeatability can be poor, cannot use again after overload of big electric current or short circuit breakdown, the influence that adjusts an error to suffer environmental temperature greatly, easily is moved by accident or refus is moved, power comsumption material of big, bad news index of much, function is backward wait for blemish. (2) temperature relay is to use bimetallic piece the relay of the disk type that makes or other form, have a structure simple, action is credible, protect limits to wait for an advantage extensively, but the start is slow, release time is long, the triangle of 3KW above receives law electromotor to should not be use. Wait for a respect to be used in great quantities in compressor of fanner, freezer, air conditioning at present. Temperature relay and hot relay are different. Temperature relay is to install in electromotor interior, rely on movement of temperature change period. And hot relay is installed go up in dynamical line, rely on movement of voltaic fuel factor. (3) protector of electronic type electromotor already developed integrated circuit to already developed circuit of large model of small processing chip up to now by transistor, from the function general component is photograph protection, integrated protection (muti_function protection) , temperature protection and intelligent protection. This kind of protector has delicacy of energy-saving, movement, definition tall, impulse withstand oscillatory, repeatability function of good, protection all ready, power comsumption is small wait for an advantage. 1.

Electromotor protector (electric machinery protector) it is the change with check line electric current (include to adopt, foreword, negative phase-sequence, 0 foreword and flow too) for the principle, can detect photograph or overload signal. Divide outside having photograph protection function, still had had bear, locked-rotor to protect a function. 2.

Intelligent protection: The electromotor protector of market protection, telemetering, communication, remote control and an organic whole, break photograph, overload, short circuit to electromotor happening, owe pressure, be pressed too and protection comes true when the breakdown such as leakage of electricity, still have voltaic voltage to show, time control, software is diagnosed oneself, the incoming telegram restores oneself, start order oneself, breakdown memory, mix from trivial far pass call the police, around of breakdown of the electric current when indication breakdown, voltage twinkles with code name give a warning, configure RS485 communication interface, realize computer couplet net. At the same time but monitoring, monitor the function such as 256 electromotor job. (4) electric machinery protects the protector of principal port electromotor in national economy and energy-saving career (electric machinery protector) it is to generate electricity, the important parts of an apparatus of the power supply, system that use phone. It is to cross bedding face of industry, quantity the energy-saving mechanical and electrical products with wide, energy-saving distinct effect. Permeate electric domain almost; It is industry, agriculture and national defence construction and people life what normal production and safety work is important assure, there are the significant position that cannot replace and effect in national economy and course of study of section what one is particularly good at. " People's Republic of China is managing energy law " regulation: "Energy-saving it is to point to strengthen with can manage, adopt a technology to go up economically feasible, reasonable and environment and society are OK susceptive measure, decrease to produce the loss in consuming each link and waste from the sources of energy, more effective, reasonable favourable geographical position uses the sources of energy " ; "A of energy-saving development economy long-term strategic principle " . Energy-saving it is systematic project. According to not complete count, the amount of 1KW-320KW low-pressure electromotor that the whole nation runs is 60 million, occupy electrified wire netting to use the 70% above of n, it is the power plant with the most wide application in industry and agriculture and commercial system. The whole nation is annual amount of burn down electromotor makes an appointment with 3 million, the capacity is 1 billion kilowatt, annual only electromotor is in burn down process with respect to number of bad news phone millions upon millions degrees, repair cost to be as high as 10 billion yuan several or so, cause loss of shutdown stop production to amount to 10 billion yuan several unexpectedly. Only afore-mentioned charge do not calculate, still can cause the power after electric machinery is repaired to drop, power consumption is big, function becomes poor to affect an enterprise to be produced normally directly. Press afore-mentioned circumstance illustrate: (one) the whole nation wastes electromagnetism line every year to make an appointment with 10 thousand kilograms 100 million because of maintaining electromotor, be like little production line of 10 thousand kilograms of 100 million electromagnetism (need every kilograms to use phone 33.

4 degrees) annual but managing with report 33.

400 million degrees. (2) electromotor protector (electric machinery protector) with business economic benefits relation computation formula is as follows: Qs= electromotor repairs the protector that expend × electric machinery of reliable coefficient ＋ tears open loss of shutdown of the ＋ that hold cost - protector purchases cost - electromotor of =(of protective installation cost repairs the protector that expend × reliable coefficient - protector purchases cost) ＋ (electric machinery tears open loss of shutdown of the ＋ that hold cost - protective installation expends) =(is direct: Have electromotor of a 55KW, be like cost is repaired to be 2500 yuan after burning out, configuration uses reliable coefficient for 98% , price is protector of 490 yuan of electromotor, it makes electric machinery spares burn down and the QZ of direct economic benefits of generation is: QZ= electromotor repairs the protector that expend × reliable coefficient - protector buys cost =2500 × 98% - 490=1960 (yuan) direct and economic scale: 100%=78 of ρ =1960/2500 × .

4% computation result: The user buys the result of electromotor protector, can save 1960 yuan, economic scale is 78.

4% . Note: Protector of here hypothesis electromotor (electric machinery protector) reliable coefficient is 100% (3) fetters with electromotor in production of industry and agriculture in equipment, often existence electromotor is long-term " car of big Ma La " and change the long-term sky with carry medium travel carries, the have rendered great service that created electric energy and without the severe loss of result. The UL-E2 that my company produces and muti_function energy-saving electromotor protector (electric machinery protector) be in according to electromotor light (empty) when carrying, reduce its carry voltage, can raise the principle of its power factor and work efficiency. Detect through dogging automatically what electric machinery runs voltage and electricity is phasic, according to condition of load of phasic analysis electric machinery, self-correcting electric machinery runs voltage, make electric machinery flux cooperates torsion of electric machinery load effectively, reduce electric machinery effectively not to have work loss, loss of have rendered great service, excitation loss, improve electric machinery work efficiency, achieve energy-saving fall bad news purpose. Use Y, △ is changed electric machinery light (empty) Zai Shiduan voltage drop is small for original 3/3 times, caustic of electric machinery iron also falls the 1/3 that is a principle (because the iron caustic of electric machinery and the square that carry voltage become direct ratio) at the same time the electric current of electric machinery also drops subsequently, because the square of cupreous caustic and electric current becomes direct ratio, so cupreous caustic also drops subsequently, achieved energy-saving goal. Illustrate: JO2, 52, electromotor of 4 three-phase asynchronous is as follows about the number: Pe=10KWVe=380Vne=1452 turns / cent Mfz=0.

If,1Me is in in movement stator winding by " △ " form instead " Y " after connection, COS ψ by 0.

2996 rise 0.

634, efficiency μ by 66.

7% rise 79.

7% . Stator power input will arrive by 1514W 1255W. If carry 20 hours gently everyday, press 300 weekday every year, annual and managing electric energy: A= (1.

514-1.

255) 300=1554 spends 20 × of × effect of report of this unit division is distinct, when carrying for nothing, but will carry starting electric current to drop for nothing 70% above, make power input is reduced 70% the left and right sides, empty running power is reduced 47.

6% , empty report carrying a red-letter day 50% above are highest can amount to 68% , often be in the electromotor with low load and laden frequent change to those especially, rate of average length report is in (16 ～ 40) % , raised power factor, reduced the cupreous damage of caustic of line of electrified wire netting and transformer, report of a kind of better electric machinery section starts can yet be regarded as integrated device. Accordingly, electromotor protector (electric machinery protector) can make sure industry and agriculture is produced normally not only, raise manufacturing efficiency and economic benefits, and there also is important sense in energy-saving career. 5, next great strength foster those who have integrated capacity to promote personnel (one) be in charge of a leader what to must know as the proprietor of an enterprise above all is buyer's market is promoted with how, must say than promoting personnel to meet able, can chair make sale strategy and countermeasure carry out a sale to engineer plan, the moment of truth can go out to hold the post of immediately. Let sale employee lead ability and product satisfaction to yours. (2) promote personnel to should have faithful enterprise, sincerity to entertain a guest, assiduous study, diligent at creation, wait for the necessary quality such as the person with the ceremony, of the member that return the member that must have technician, after service, plugger, information (5) integrated ability, otherwise, not be a competent bagman. (3) fall in the condition of buyer's market, in the orgnaization of the enterprise, marketting a tissue is bibcock it is Chongzhongzhi is weighed. The product is sold do not go out, other everything does not talk to go up. The enterprise must have a high quality and have (5) the sale team of integrated ability, these salespersons can be in the market know sth like the palm of one's hand of ten thousand changes in the twinkling of an eye. If the enterprise does not increase sale ability to measure, ignored promotes the work, return the model that is now, the product that will create you is many keep long in stock, economy is impossible to revitalize, the enterprise cannot fly. (4) increase promotion to publicize strength. Why to heat up relay the country already fell into disuse at 96 years of later development, still have on the base that sells 5 million every year however add without decrease? The reason has 3: 1.

It has applied history of more than 40 years, confirmed in the thought of people; 2.

The price is low; 3.

Have sale network, the user can be bought where. Electron electromotor protector, want occupational market, must use the news media such as the press TV to increase conduct propaganda, long-term conduct propaganda, sell a site with respect to what must have his, have consistency and versatility in that way like hot relay even, installation is convenient wait. (5) fall low consumption price. Current, the price on the high side of the electromotor protector that appears on the market, profit is in 100 percent above, it is even hundred, make big much user cannot be accepted, profit control is in 50% to 100 percent already pretty good. Such, your market share will increase quickly, achieve bigger economic benefits and social beneficial result, also meet faster extraction replaces hot relay the market. CNC Milling CNC Machining
