Disclosure of Invention

The invention aims to provide a phase modifier brush holder assembly to solve the problems that the normal use is influenced due to untimely maintenance caused by the fact that a general generator cannot monitor a position and the brush is troublesome to replace in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a phase modifier brush yoke assembly, includes the brush yoke subassembly, fixed mounting has brush monitoring system on the brush yoke subassembly, and the brush yoke subassembly inserts in the brush yoke seat, and the brush yoke seat passes through the bolt fastening on the conducting ring, and the conducting ring passes through screw rod fixedly connected with support, and the conducting ring is inside the support, and the support is inside through bolt fixedly connected with windshield, hinge fixedly connected with observation window is passed through on support upper portion, and is fixed with the cylinder on the observation window, and the side lower part of support is fixed with the junction box.

Preferably, a buckle is arranged at the joint of the support and the observation window.

Preferably, the brush monitoring system comprises a power supply, a GPRS receiver, a GPRS remote control switch, a monitoring module and an alarm.

Preferably, the monitoring module comprises a temperature sensor, a wear value monitoring device and a current monitoring device.
