Harmonics not only behave as current harmonics, but also because the harmonic currents on the grid cause the supply voltage to contain harmonics, which can make the voltage waveform become extremely serious, which may adversely affect other sensitive equipment on the grid, and even make it work abnormal harmonics. Excessively, the zero line current is too large, and the zero line current is too large. This is a serious fire hazard because there is no overcurrent protection device on the zero line. Unlike the phase line, there is insurance and other devices. When the current is too large, the current can be cut off. When the current on the zero line is too large, it can only be allowed to increase its temperature, accelerate the aging of the cable, and even cause a fire.
Harmonics not only behave as current harmonics, but also because the harmonic currents on the grid cause the supply voltage to contain harmonics, which can make the voltage waveform become extremely serious, which may adversely affect other sensitive devices on the power grid, and even make it work abnormally. The legal liability problem associated with the company, such as a network server in a building in the same building, caused a loss due to a sudden power outage.
The LC-RX type filter compensation device adopts the microcomputer dynamic compensation controller, and the main circuit adopts the control mode of the high-performance contactor switching filter branch, and automatically switches. The equipment has advanced technology, complete functions, high reliability, small maintenance and durability. In-situ filter compensation, improve the user's power factor and harmonic status, achieve energy saving and improve user economic benefits. The device can automatically exit the work in the event of an external fault or power failure, and automatically resumes operation after power transmission.
