Problems solved by technology

There are some problems in this kind of intelligent ring network cabinet structure: during the process of forward and reverse rotation of the motor, sometimes there will be rotation failures, such as: the motor rotation is not in place, the motor is stuck during rotation, etc., resulting in the failure of the switch to open and close. In severe cases, the motor may be burned

Embodiment Construction

[0021] Now with reference to the accompanying drawings, the embodiments of the present invention will be described in detail.

[0022] The present invention proposes a motor fault monitoring device for an intelligent ring network cabinet, which can monitor the current of the motor of the ring network cabinet, analyze the change of the motor current, compare it with the fault judgment basis, and quickly and accurately judge whether the motor is in the failure state. Moreover, after the motor fault is found, the motor can be stopped in time through emergency stop processing to prevent the motor from continuing to rotate in the fault state and burn the motor; and control the reverse rotation of the motor according to the fault state to automatically repair the motor fault. In addition, it can also process, store and intelligently learn the motor current data of motor faults, and continuously enrich the basis for judging motor faults.

[0023] see figure 1 , figure 1 It is a sc...

Abstract

The invention relates to a motor fault monitoring device and method of an intelligent ring main unit. The device comprises a master control unit, a motor current collecting module, a motor rotation control module and a fault judging module, wherein the fault judging module judges whether a motor works normally or not according to the motor current signals provided by the motor current collecting module, and the master control unit transmits corresponding commands to the motor rotation control module so as to control the operation of the motor according to the judging results provided by the fault judging module. The motor fault monitoring device has the advantages that the on-off control motor of an intelligent ring main unit switch can be protected, and reliable motor switch on and off are guaranteed.

Description

technical field [0001] The invention relates to power grid equipment, in particular to the monitoring of intelligent distribution network equipment of the power grid. Background technique [0002] The smart distribution network is an important part of the smart grid construction. It integrates modern computer technology and communication network technology to monitor, coordinate and control the equipment on the distribution network in real time. This is the necessity of the modern development of the power system. trend. The current power distribution system is developing in the direction of open, integrated and integrated comprehensive automation, in order to improve the reliability and efficiency of distribution network operation, improve the quality of power supply, reduce labor intensity, and make full use of existing equipment capabilities As well as shortening the power outage time and reducing the power outage area, it brings considerable economic and social benefi...
