Description

Technical Field

[0002] The low-voltage reactive power compensation controller is a device specially used to regulate reactive power in low-voltage power systems. It can monitor the load conditions in real time and automatically adjust the compensation capacity according to load changes, thereby improving the power factor of the system, reducing power loss, and improving power supply quality.

The utility model can monitor the temperature in real time through the temperature sensor, and automatically start the cooling fan for active cooling when the temperature is high. When the monitored temperature is very high, it means that the filter plate is blocked and affects the heat dissipation. At this time, the warning light is on to remind the staff in time that the filter plate needs to be cleaned and replaced, which greatly improves the heat dissipation efficiency of the equipment, can avoid damage to the equipment caused by excessive temperature, and is conducive to timely cleaning or replacement of the filter plate, extending the service life.
