Abstract

Provided is a motor dynamic capacitance compensation device. The compensation device comprises an isolation switch, a voltage regulator, a lightning arrester, a capacitor, a discharging coil, a fuse, an electric reactor, a fence and a ground. The isolation switch is arranged at the top of the left side of the integral body. The voltage regulator is installed at the right side of the isolation switch. The fence is installed at the periphery of the isolation switch and the electric reactor. The electric reactor is installed at the inner side of the fence and is fixed on the ground vertically. The electric reactor is connected with the interior of the capacitor through a wire. The discharging coil is arranged between the electric reactor and the voltage regulator. The fuse is installed at the lower side of the discharging coil and the lightning arrester. The lightning arrester is installed at the left and lower side of the discharging coil. The capacitor is installed at the lower side of the fuse. The device employs the voltage regulator to change the end voltage of the capacitor, therefore a reactive output capacity is changed, and thus a reactive power provided by the device to a system is adjusted automatically.

Description

A kind of motor dynamic capacitance compensating device
Technical field
