Ac frequency conversion compressor motor is general three-phase ac asynchronous motor, dc brushless dc permanent magnet motor is of frequency conversion compressor rotor motor. Three phase motor Frequency conversion power module is also called intelligent power transistor, referred to as "IPM, a thick film integrated encapsulation. This article focuses on the output of the ac frequency conversion air conditioning circuit, there single phase induction motor are three kinds of common frequency conversion power circuit. One kind is to use a separate IPM, as shown in figure 1, IPM 11 terminals, direct welding outside control main edition; A circuit board is made of IPM and frequency conversion circuit integration, the whole circuit in the polyester encapsulation, and control ANP gost motor main board with a communication port control, is unable to repair; One is using IPM and drive circuit or the power supply circuit of frequency conversion power template, IPM has 21 terminal, control element can be seen, can repair, and control main board have signal connection.

Until 1938, invented the crossbar (cross bar) switches to solve the above problems, relative to the step by step system switches, important improvements it has two aspects: 1. The use of the contact pressure relay control connection array instead of the big action step by step, thus reducing the wear and noise, improve the reliability and the connection speed; 2. The transition from direct control to indirect control method, so that users dial pulse is not directly control switch action, and the first received by register, electric fan motor storage, and then through the marker drive connector, indirect continue to complete the users. This way of indirect control separate control part way with words, to increase the control efficiency, flexibility and picked up speed.

Because the crossbar switch has a series of advantages, so it occupies an important position in the development of the telephone exchange, has been widely used, until now, quite a number of magnet generator countries in the world and the public telephone network is still in the minority areas of China and use the switches With the birth of the semiconductor devices and computer technology and the rapid development of violently hitting the traditional electromechanical exchange structure, make it to the electronic. Bell companies in the United States after the hard work in 1965, produced the world's first commercial stored Three phase motor program control electronic switch (No. 1 ESS), which marks the telephone switches from the mechanical age into electronic age, making exchange technology in the era of change. Because the electronic switch has small volume, quick speed, easy to provide efficient and reliable service, etc, caused great interest from all over the world. In the process of development have developed various types of electronic switches.

1,the seal quality reasons:At the scene of the collapse of the transformer terminals can be found at a time,leakage of oil terminal blocks most of fastening nut loose,install this doesn't mean that it did not tighten,with plane flange rubber gasket,for the first time after fastening tend to loose because of plastic deformation of ac induction motor the rubber gasket,need a second fastening.Transformer and our factory has been running for many years,there is no rubber gasket deformation problem,may explain why only is rubber gasket ageing lose elasticity,reducing the pressure on the surface of the flange connection.According to my years of generator generator set experience in maintenance,air isolation rubber gasket to run more than ten years should not have what problem.

4. high starting torque

Such as the transformer operation of our factory in nanjing,cichang has more than 20 years,did not find for porcelain set gasket aging oil leakage.Presumably liling porcelain production of transformer set gasket exist quality problems.2,environmental temperature change electricalmotor1.blogspot.com reasons:Refer to instruction for use of current transformer,transformer running environment temperature 40 ℃,the highest temperature is + minimum temperature of 40 ℃.Our factory area this summer outdoor certainly higher than 40 motor vehicle ℃,the highest temperature field measurement of the surface temperature is close to 50 ℃.After each part of the summer heat equipment thermal expansion,due to environment temperature drop after high temperature season,but all kinds of material shrinkage is not consistent with the temperature,cause the leakage of oil from the surface.This point in our plant is particularly prominent.
