Abstract
The invention relates to a power system fault indicator. According to the structure of the indicator, A phase, B phase and C phase short circuit fault sensors and a grounding fault sensor are connected with a readout instrument through a cable and/or an optical cable and provided with coils for detecting the short circuit and earth fault and causing impulse current. The indicator can perform real-time monitoring and provide fault messages; maintenance personnel can find a fault zone quickly according to the warning signals of the indicator and break the fault zone, therefore power supply in a non-fault zone can be recovered timely, large amount of working time can be saved, and the power cut time and range can be reduced.
Description
Technical field
The present invention relates to a kind of equipment that detects short circuit and earth fault, relate in particular to a kind of electric power system fault indicator.
Background technology
Short circuit and earth-fault indicator are the equipment that detects short circuit and earth fault.In the looped network distribution system, particularly use in a large number in the system of ring net load switch, if short trouble or earth fault have occured in the next stage distribution network system, the electric power system of upper level must be carried out disjunction in setting time, to prevent major accident.Fault detect of the prior art sometimes can't find rapidly the section that breaks down, thereby cause power off time long, and power failure range is large.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of electric power system fault indicator is provided, solved the problem that can't find rapidly the section that breaks down in the prior art.
To achieve these goals, the technical solution used in the present invention is:
A phase short trouble sensor, B phase short trouble sensor, C phase short trouble sensor and ground fault sensor are connected with readout instrument by cable and/or optical cable; A phase short trouble sensor, B phase short trouble sensor, C phase short trouble sensor and ground fault sensor are equipped with and detect the coil that short circuit and earth fault cause pulse current.
Described readout instrument is provided with time reset circuit and assignment circuit; The housing outer surface of readout instrument is furnished with test/reset button.
Described A phase short trouble sensor, B phase short trouble sensor, C phase short trouble sensor and ground fault sensor are provided with audible-visual annunciator.
Advantageous effect of the present invention is as follows:
The present invention can carry out Real-Time Monitoring and point out failure message, the maintenance personal can find rapidly the section that breaks down according to the alerting signal of this indicator, divide and disconnect fault section, thereby in time recover the power supply of non-fault section, a large amount of working times be can save, power off time and power failure range reduced.
