The output of motor protectors in China keeps breaking records

Motor protector is an important component of power generation, power supply and power consumption system. It is a cross industry, large quantity and wide range of energy-saving mechanical and electrical products with significant energy-saving effect. It has penetrated into almost all fields of electricity consumption; it is an important guarantee for the construction of industry, agriculture and national defense as well as the normal production and safety work of the people, and plays an irreplaceable important role in the national economy and energy conservation. "2011-2015 China motor protector Market special research and investment direction Research Report" released by China industry information network pointed out that in 2008, China's motor protector output reached 65 million units, with a year-on-year growth of 15.2009-2010, driven by the strong drive of the motor industry, China's motor protector output repeatedly reached new highs, with a year-on-year increase of 19 and 20, and the output reached 7730 respectively Million and 92.7 million.
As an important part of the drive system, motor plays an important role in the national economy. Its use has almost penetrated into all walks of life. It is an important guarantee for the normal operation of industry, agriculture, national defense construction and people's life. Therefore, it is very important to ensure the normal operation of the motor, which causes the motor to burn down or even cause major safety accidents According to incomplete statistics, the amount of electricity consumed by motor burning alone is tens of millions of kWh every year. The number of motors burned is more than 200000 times, and the capacity is about 40 million kilowatts. The electromagnetic wire consumed for maintenance is about 50 million kg, and the repair cost is 2 billion yuan. The loss caused by shutdown and shutdown is an immeasurable huge amount. Therefore, the protection of motor is of great significance in energy saving, improving production efficiency and economic benefits and ensuring safety in production. China's motor protection device has experienced several stages, such as comprehensive imitation of the Soviet Union, self-design, upgrading and intelligent development. It is worth mentioning that the development of microprocessor technology in recent years provides a hardware platform for the intelligent and multifunctional development of motor protector, which makes motor protection enter a stage of rapid development.
