Abstract
The invention discloses a safety maintenance system for high-voltage switches and relates to the technical field of maintenance of high-voltage switches in power systems. The safety maintenance system for high-voltage switches comprises a cabinet body and a cabinet door arranged on the same. A high-voltage switch fixed contact is arranged in a cavity of the cabinet body. The inner cavity wall of the cabinet body is fixedly provided with an infrared sensor close to the high-voltage switch fixed contact. An acoustic alarm electrically connected with the infrared sensor is further disposed on the inner cavity wall of the cabinet body. The infrared sensor is detachably installed nearby the high-voltage switch fixed contact to form an infrared detection and alert area. The infrared sensor is capable of timely sensing and detecting a maintainer mistakenly entering the alert area and controlling the acoustic alarm to give out warning sound, and an alarm LED lamp flashes nonstop to remind the maintainer of safety. The safety maintenance system for high-voltage switches is safe and reliable, enables maintenance accidents to be reduced and enables the maintainers to be more aware of safety.
Description
Technical field
The present invention relates to the high-voltage switch gear service technique field in the electric power system, relate in particular to a kind of safety maintenance system for high-pressure switch.
Background technology
High-voltage switch gear plays the important function such as break-make, control or protection in electric power system generating, transmission of electricity, distribution, electric energy conversion with in consuming, and is the indispensable vitals of electric power system.Because high-voltage switch gear is being controlled the above high pressure of 10KV, the break-make of high electric current, so the general insulation-encapsulated of high-voltage switch gear is in high-tension switch cabinet, the fixed contact of high-voltage switch gear directly is connected with power supply buses, if power supply buses does not have a power failure, static contact of high-voltage switch is charged just always so.In actual motion, the cabinet door of maintainer's opening high pressure switch cubicle is inevitable to high-voltage switch gear or replacing and the maintenance of carrying out parts of other electric elements that is installed in wherein, at this moment, even behind the disconnected lock of high-voltage switch gear, charged fixed contact still might the tested personnel of repairing touches and causes human casualty accident.And device or the system that warns people's safety inspection is not set in the existing high-tension switch cabinet, so maintainer's electric shock accidents often occurs in upkeep operation.
Summary of the invention
Weak point for above-mentioned prior art existence, the object of the present invention is to provide a kind of safety maintenance system for high-pressure switch, can improve maintainer's awareness of safety, the electric shock accidents that occurs in the time of reducing again maintenance, can eliminate safe hidden trouble, guarantee the safe operation of electrical network.
Purpose of the present invention is achieved through the following technical solutions:
A kind of safety maintenance system for high-pressure switch, comprise cabinet and the cabinet door that is arranged on the cabinet, be provided with static contact of high-voltage switch in the cavity of cabinet, cabinet is fixed with infrared inductor at the internal chamber wall near static contact of high-voltage switch, also is provided with the voice alarm device that is electrically connected with infrared inductor on the cabinet internal chamber wall.
In order to realize better the present invention, the outside of described static contact of high-voltage switch is provided with the insulation blocking box, and the internal chamber wall of insulation blocking box and cabinet is screwed.
Further, the quantity of described infrared inductor is two, and is symmetrically set in the both sides of insulation blocking box.
As preferably, the internal chamber wall of described cabinet is provided with the warning LED lamp that is electrically connected with infrared inductor.
The present invention compares than prior art, has the following advantages and beneficial effect:
The present invention detachably is equipped with infrared inductor near static contact of high-voltage switch, infrared inductor forms an infra-red detection warning region, when maintainer's maintenance is strayed into this warning region, infrared inductor is responded to detection in time, and the control voice alarm device sound that gives the alarm, ceaselessly glimmer with alarm LED lamp, remind the maintainer to take care.And the static contact of high-voltage switch outside is provided with the insulation blocking box, and this insulation blocking box can effectively be stopped the maintainer and touch fixed contact and cause serious electric shock accidents.This examination and repair system safety, reliable can not only reduce the maintenance accident, can also improve maintainer's awareness of safety.
