Intelligent load balancer

Abstract

The invention relates to power compensation equipment, in particular to an intelligent load balancer. The intelligent load balancer comprises a sampling module, a main power supply input end, a voltage regulator module, an isolation transformer, a power supply detection module, a datum grounding end, a main controller, a compensation switch, a compensation module, a driver and a main power supplyoutput end; the driver is arranged between the isolation transformer and the main power supply output end; the driver is positioned between the compensation switch and the main power supply output end; the driver is connected in parallel with a driver isolation switch; one end of the driver isolation switch is connected between the input end of the driver and the compensation switch; and the otherend of the driver isolation switch is connected to the output end of the driver. The intelligent load balancer has the beneficial effects that coordinated operation of variable frequency speed regulation and power compensation functions can be implemented; and the intelligent load balancer has a very good energy-saving effect.

Description

technical field [0001] The invention relates to a power compensation device, more specifically an intelligent load balancer. Background technique [0002] At present, my country's total energy consumption is increasing year by year, among which industrial energy consumption accounts for about 70% of the country's total energy consumption, and motors are the main power-consuming terminals in the industrial field, accounting for 75% of the total industrial power consumption. . [0003] There are two working conditions of speed regulation and non-speed regulation in the application of motors, which account for more than 60%. The energy consumption problem of motors that do not require speed regulation is almost ignored by people. Most non-speed regulation motors have simple protection and lack of fault analysis. And records, low-efficiency operation, serious problems of electric energy waste. [0004] At present, it is widely used to install shunt capacitors on the low-voltage...

AI Technical Summary

Problems solved by technology

This invention cannot accurately perform power compensation according to the actual needs of the circuit, and cannot be used normally when the voltage of the power supply line is unstable, and cannot control the motor speed and torque

Moreover, the power compensation equipment in the traditional way cannot be used in coordination with the frequency converter, resulting in a large power loss
