Magnetic Contactor
The development of low-voltage electrical appliances and new technology - low-voltage electrical appliances, new technologies - electric industry
Since 1995, China's power industry maintained a rapid growth rate. The end of 2004, China's installed capacity reached 440 million kW, 2004 annual generation capacity of 2.1 trillion kW? H. It is estimated that by 2010 China's installed capacity will reach 700 million kW, 2020 will reach 10kW.
New year Generator Calculated for the 20 million kW installed capacity (conservative), supporting high-voltage circuit breakers per year 200,000 units, high pressure Isolating switch About 40 million, low-voltage electrical components requirements more (about 200 million), of which circuit breaker (ACB), takes up about 46 million units, molded case circuit breakers (MCCB) about 440 million units, AC contactor ( ACC) of about 32 million units. Shows that economic development led to the demand for electricity and growing dependence, as borne power transmission and distribution, power equipment, low voltage electrical protection and control is especially important role. At present, every year around the world invested heavily in research on low-voltage electrical appliances, development.
A low voltage electrical equipment industry development and prospects
(A) low-voltage electrical products in China History
Recent years, low-voltage electrical industry, a dramatic change in the development of low-voltage electrical products to a new stage.
The development of China's low-voltage electrical products can be divided into the following stages: 20 full imitation '50s the Soviet Union, in the 20th century in imitation of 60 to 70 years based on first-generation unified design products, 70 to 80 years in the update updating and introduction of foreign advanced technology manufacturing second-generation products, 90 new foreign technology to track their own third-generation smart appliances, and recently developed the fourth generation of intelligent communications appliances available. The fourth generation of product has excellent performance, reliable, small size, composition, modular, modular features, the overall technical performance at or near abroad in the 20th century the late 80s, early 90s level.
China at the end of 2003, low-voltage electrical components certified by 3C over 13,000 units, low voltage device certified by 3C over 6000 units, production of low-voltage electrical products in recent 1000 series, the output value of about 200 billion RMB.
(B) low-voltage electrical design features As low-voltage electrical power in the running there, magnetic, optical, thermal, mechanical and other energy conversion, the conversion process of the law are mostly non-linear, many phenomena but also a transient process, it enables low-voltage Theoretical analysis of electrical appliances have become extremely complex.
Low-voltage electrical traditional theory of the "electrical contact, arc, electromagnetic, thermal effects and electric force effect" necessary in addition to relying on theoretical derivation and analysis of operations, but also must rely on the experience of mature and reliable data.
Even so, the design and calculation of actual performance data and products will still have a big gap between the sometimes must be verified by tests. Therefore, the low-voltage electrical product development cycle is longer, investment is relatively large.
Order to meet the growing power grid capacity, low-voltage power distribution and control systems become more complex, on the low-voltage electrical products, performance and structure of a higher demand.
The same time, with the scientific and technological progress, new technologies, new processes, new materials appear for the low-voltage electrical product development provides a good condition.
(C) low-voltage electrical Prospect Low-voltage electrical power system development depends primarily on the development needs and new technology, new materials, new technology research and application. Of the 20th century developed a new type of 70,80 main limiting electrical appliances, vacuum appliances, leakage of electrical and electronic appliances.
From the late '80s, the traditional low-voltage electrical products in general made a new generation of high-performance, high reliability, small size, multi-functional, combination, modular, electronic, intelligence requirements.

(EE problem solving) Relay vs. Magnetic contactor?
what are the differences between a relay and a magnetic contactor? how can one explain the principles of relay and that of a magnetic contactor on a lay-man's term?
All magnetic contactors are a type of relay, but relays can be significantly more complicated than contactors.
The contactors is primarily used for switching larger power circuits (such as motors, for example), since the control logic components cannot meet the current & voltage duty of the power circuit.
Relays can be as simple as 12 V dc solenoids with 12 V, 0.5 A rated contacts. Or they can be as complicated as microprocessor-based devices used to detect disturbances (faults) on the power system and signal a local or remote switching device (breaker) to trip the circuit.
