Voltage-regulating and power-saving power distribution cabinet

Abstract

The invention provides a voltage-regulating and power-saving power distribution cabinet, which has the advantages that not only is a switch function of a control circuit of a traditional power distribution cabinet is reserved, but a function of regulating voltage fluctuation phenomena and electric energy waste phenomena in a power grid line is added. The voltage-regulating and power-saving power distribution cabinet is connected to a high voltage circuit and has the technical scheme of comprising an outer shell of the power distribution cabinet, a detection and control module, a voltage-regulating and power-saving module, a security protection module, an input end and an output end, wherein the three modules are mutually connected and are arranged in the outer shell of the power distribution cabinet. Through correspondingly operating a control button of a panel of the power distribution cabinet, the functions of voltage regulation and electricity conservation can be fulfilled.

Description

technical field [0001] The invention relates to a voltage-regulating and power-saving power distribution cabinet, in particular to a voltage-regulating and power-saving power distribution cabinet with detection control and safety protection functions. Background technique [0002] With the development of China's electric power industry and the improvement of the country's agricultural power grid renovation project, the phenomenon of low voltage at the end of the power grid has been generally improved. However, the resulting problem is that the voltage of the power grid is generally high, especially when the power load is low, it is also a common phenomenon that the voltage of 380V rises to 450V, resulting in increased loss in the power grid and a low pass rate of power supply quality. And the power consumption of all equipment increases, and often burns out the motor, reduces the service life of the equipment, and increases maintenance and repair costs. [0003] At present,...

However, the resulting problem is that the voltage of the power grid is generally high, especially when the power load is low, it is also a common phenomenon that the voltage of 380V rises to 450V, resulting in increased losses in the power grid and a low pass rate of power supply quality. And the power consumption of all equipment increases, and often burns out the motor, reduces the service life of the equipment, increases maintenance, repair costs

[0003] At present, the main function of the power distribution cabinet on the market is to disconnect or connect the power supply of the high and low voltage lines. It has a single function and does not have the function of on-load voltage regulation. Voltage pass rate
