Abstract
The invention discloses a monitoring system for a working state of a vacuum circuit breaker. The system comprises a controller. A vacuum circuit breaker and an insulating pull rod are arranged in an equipment box; and a moving contact of the vacuum circuit breaker is connected to the upper end of the insulating pull rod. Position sensors capable of monitoring the lower end position of the insulating pull rod are arranged on the inner wall of the equipment box; and signal output terminals of the position sensors are connected with the controller. The two position sensors are arranged at positions expressing the heights the lower end of the insulating pull rod during the opening and closing of the vacuum circuit breaker. Besides, a temperature sensor and a humidity sensor are arranged inside the equipment box; and the output terminals of the temperature sensor and the humidity sensor are connected with the controller. According to the invention, correlated data of working states from multiple aspects of the vacuum circuit breaker can be obtained to monitoring the working state of the vacuum circuit breaker; and thus a reference basis is provided for the staff to carry out maintenance on the vacuum circuit breaker.
Description
Technical field
The present invention relates to vacuum circuit breaker technical field, particularly a kind of vacuum circuit breaker operation condition monitoring system.
Background technology
Vacuum circuit breaker because of after its arc-extinguishing medium and arc extinguishing the dielectric of contact gap be all fine vacuum and gain the name, be widely used in electric power network.In the course of the work, the switching of separating brake combined floodgate can cause the heating of contact to vacuum circuit breaker frequently, the long-term damage that contact so even can occur, and affects completing of breaking-closing operating.
And outdoor high-voltage vacuum breaker is generally placed in equipment box, but equipment box is chronically exposed to outdoor, and temperature is affected relatively big by weather, and the heat in addition sent during chopper work itself makes temperature in equipment box raise, and can affect the life-span of contact.And in overcast and rainy season, the dampness in air easily enters in breaker apparatus case, and slowly piles up, and forms water droplet, affects normal operation of circuit breaker and service life.
Summary of the invention
The technical problem to be solved in the present invention is: provides a kind of vacuum circuit breaker operation condition monitoring system, is obtained by many-sided reference data, and the maintenance of vacuum circuit breaker is provided reference frame for staff by the duty of monitoring vacuum circuit breaker.
Technical scheme that the present invention takes is particularly as follows: a kind of vacuum circuit breaker operation condition monitoring system, including controller；Vacuum circuit breaker and insulated tension pole are arranged in equipment box, and the moving contact of vacuum circuit breaker connects the upper end of insulated tension pole；The inwall of equipment box is provided with the position sensor that can monitor insulated tension pole lower end position, and the signal output part of position sensor connects controller；Number of position sensors is two, and when being respectively arranged at vacuum circuit breaker separating brake and close a floodgate, insulated tension pole lower end institute is in height；
The outfan being additionally provided with temperature sensor and humidity sensor, temperature sensor and humidity sensor in equipment box connects controller respectively.
Further, in order to facilitate the heat radiation of vacuum circuit breaker, equipment box is provided with louvre；Being additionally provided with radiator fan in equipment box, the control end of radiator fan connects controller.
Further, the system of the present invention also includes humiture alarm unit, and the input of humiture alarm unit connects controller.The predeterminable Threshold of Temperature And Humidity of controller, and real time humiture data and threshold data are simply contrasted, and then control the work of humiture alarm unit, to facilitate staff know in time or safeguard.
In the present invention, described position sensor adopts photoswitch, and the lower end of insulated tension pole is provided with the reflecting plate that can reflect light beam.
Beneficial effect
In use, position sensor can know the divide-shut brake position of vacuum circuit breaker in time, to confirm whether vacuum circuit breaker completes divide-shut brake task；Temperature sensor and humidity sensor can obtain the temperature and humidity information in equipment box in real time, when humiture needs to be adjusted, staff can be known from the warning of humiture alarm unit from controller end or directly, lead to thus available radiator fan carries out the air fluidizer in equipment box, do not only reach heat radiation purpose, also can prevent the formation of steam, can effectively ensure that the normal operation of vacuum circuit breaker, extend the life-span of vacuum circuit breaker simultaneously.
