The phase advancer is an industrial production equipment used in manufacturing enterprises, which can reduce the power consumption loss caused by large, medium and small motors. It is divided into a stationary immovable phaser and a variable load phaser.

In China, the power consumption of electric motors can account for 60% to 68% of all industrial electricity. The loss of power consumption caused by inductive loads such as electric motors is the key source of power consumption without loss of power, and many large and medium-sized motors are also The key power consumption machinery and equipment of factories and mines, therefore, how to reduce the power consumption caused by large, medium and small motors has become an important factor for many manufacturing enterprises to save energy and reduce emissions. The phase advancer should be born from time to time. According to the load condition, the phase advancer can be divided into two types: static immovable phaser and variable load phaser.

The static phase advancer is a reactive power local compensation device dedicated to energy saving and emission reduction design schemes for large, medium and small entangled asynchronous motors. This is in the generator rotor control loop, according to the change of the motor rotor current amount and the position of the motor rotor operating voltage, thus changing the positional relationship between the motor stator current and the working voltage, exceeding the power factor and high efficiency of the lift motor itself. , to improve the motor load working capacity, reduce the stator current of the motor, reduce the loss of the motor itself.

The compensation of the reactive power of the static phase advancer is substantially different from the compensation of the parallel capacitor of the stator side of the motor. Capacitance compensation only compensates for the reactive power of the power network other than the motor. It only reduces the amount of reactive power transmission on the power network, and the main parameters of the motor's own operation, such as the current amount and power factor of the motor, are not changed.

The static phaser is not the same as the self-excited (rotary) camera. The LP series product phaser uses excellent AC-AC inverter principle and micro-machine and thyristor control system. It can fully track the change of motor operation and fully automate the relevant main parameters to improve the actual compensation effect. It is Self-excited camera can't be guaranteed. Moreover, the LP series products are static and non-movable phase-injectors. They are free from the self-excited camera "commutator" structure. They are very afraid of floating dust, short cycle, and frequent maintenance. The phase structure has no rotating components and is not afraid of dust. With high credibility, long service life and convenient maintenance, it is an ideal new and new technology product to replace the self-excited camera.

The stationary fixed phase advancer can be generally applied to the local compensation of large and medium-sized wire-wound asynchronous motors in the manufacturing industries such as concrete, chemical plants, wood processing plants, sugar industry, steel, metallurgical industry, mining and other manufacturing industries.
