Problems solved by technology

[0002] The existing low-voltage reactive power compensation device has a complex structure and disorderly wiring, which is not conducive to personnel maintenance and installation, and its work relies on the traditional contactor action to realize switching capacitors, and cannot adjust the reactive current of the capacitor with the change of load. Compensation and overcompensation exist at the same time, prone to overvoltage, reverse reactive power to the grid, and switching operations are prone to overvoltage and closing inrush current

Abstract

The invention discloses a low-voltage complete reactive power compensation device, which comprises a cabinet body and an insulating support, wherein the cabinet body is internally provided with a circuit breaker, a controller and one than one capacitance compensation circuit, wherein the circuit breaker is connected with a power grid through a copper bar, an output end of the circuit breaker is connected with the capacitance compensation circuits, an input end of the controller is connected with a power factor controller button, an output end is connected with a switching switch, the capacitance compensation circuit comprises a fuse, a switching switch and a reactive power automatic compensation capacitor which are sequentially connected, and the a disconnecting switch of a fuse set is connected with the fuse. The insulating support is in the shape of grids and used for placing components and circuits in the cabinet body. The low-voltage complete reactive power compensation device is simple in structure and orderly in wiring, and can adjust reactive current of the capacitor along with variations in load. The device disclosed by the invention is long in service life, and convenient in maintenance and installation.

Description

technical field [0001] The invention relates to a power grid equipment, in particular to a low-voltage complete set of reactive power compensation device. Background technique [0002] The existing low-voltage reactive power compensation device has a complex structure and disorderly wiring, which is not conducive to personnel maintenance and installation, and its work relies on the traditional contactor action to realize switching capacitors, and cannot adjust the reactive current of the capacitor with the change of load. Compensation and overcompensation exist at the same time, prone to overvoltage, reverse reactive power to the grid, and switching operations are prone to overvoltage and closing inrush current. Contents of the invention [0003] In order to overcome the complex structure of the existing low-voltage reactive power compensation device, the wiring is disorderly and disorderly, which is not conducive to personnel maintenance and installation, and cannot effec...
