Description
Technical field
The utility model relates to transformer station's high-voltage earthing technology, particularly relates to transformer station's high-voltage earthing handcart and supervisory control system thereof.
Background technology
Along with the development of Chinese national economy and improving constantly of people's material and culture, electricity needs is increasing, has higher requirement to electrical power services quality.
For this reason, we are studied transformer station's high-voltage earthing handcart contact dirt-proof protector.
The function of transformer station's high-voltage earthing handcart is: 1, the contact of high-voltage earthing handcart and contact arm are arranged on short circuit handcart being connected copper bar by contact arm, make a major loop ground.2, effectively ensure that loop reliable ground, the overhaul of the equipments moment is in security context work.
But when high-voltage earthing handcart is at ordinary times without service work, usual fixation is placed in switch gear room, and contact is exposed, without any safeguard measure.Because high-voltage earthing handcart long-term storage is in open environment, high-pressure conductive contact can be subject to the impact of chemical analysis, humiture etc. in air, makes high-pressure conductive contact by wet, oxidation, long-pending dirty dirt.Once high-pressure conductive contact contaminated with insulation connecting portion after, the contact-making surface of high-pressure conductive contact reduces the rotten deterioration of insulating part, especially under the high temperature conditions, the more perishable deterioration of organic insulation part, insulation property reduction constitutes insulation weak-point, causes imperfect earth, causes personal injury accidents.At present; the conductive contact protection problem of most of electric power enterprise to high-voltage earthing handcart for subsequent use does not also draw attention; what have is only be used as some basic demands to making in system; specifically using and specification not enough in managing; also do not have a set of actual, effective method to accomplish effective management and supervision to the conductive contact of high-voltage earthing handcart entering depositing between standby period, lack effective technological means or measure is supported.
Utility model content
The technical problems to be solved in the utility model is: first, because high-voltage earthing handcart long-term storage is in open environment, high-pressure conductive contact can be subject to the impact of chemical analysis, humiture etc. in air, makes high-pressure conductive contact by wet, oxidation, long-pending dirty dirt.Once high-pressure conductive contact contaminated with insulation connecting portion after, the contact-making surface of high-pressure conductive contact reduces the rotten deterioration of insulating part, especially under the high temperature conditions, the more perishable deterioration of organic insulation part, insulation property reduction constitutes insulation weak-point, causes imperfect earth, causes personal injury accidents.Then, specifically using and specification not enough in managing, also do not have a set of actual, effective method to accomplish effective management and supervision to the high-pressure conductive contact of high-voltage earthing handcart entering depositing between standby period, lack effective technological means or measure is supported.
The technical scheme that the utility model provides is: a kind of transformer station high-voltage earthing handcart, comprise earth handcart body, with high-pressure conductive contact on described earth handcart body, described high-pressure conductive contact is provided with protective sleeve, described protective sleeve comprises left shell and right shell body, described left shell and right shell body inner surface are respectively equipped with laying, described left shell one side and right shell body one side are connected by hinge, described left shell opposite side and right shell body opposite side by magnetic key operated lock folding, auxiliary contact is established in magnetic key operated lock, at auxiliary contact, place is provided with contact switch.
Further, described contact switch is key switch.Conventional switch, convenient and practical.
Further, described laying takes sponge material, protection high-voltage handcart contact, antifouling, moistureproof, plays protection against oxidation.
A kind of transformer station high-voltage earthing handcart supervisory control system, for monitoring above-mentioned transformer station high-voltage earthing handcart, comprise switch signal acquisition module, remote control module and alarm module, described contact switch connects with switch signal acquisition module, described switch signal acquisition module connects with remote control module, and described alarm module is connected with described remote control module.Under normal circumstances, high-voltage earthing handcart is emitted in hyperbaric chamber at ordinary times or concentrates and is emitted in spare unit storehouse, and left shell on earth handcart and right shell body are closure states, when deployed, when left shell and right shell body are opened, contact switch button is upspring, switch signal acquisition module collects switching signal, and be transferred to remote control module, by switching signal, remote control module judges that the closed of left and right housing is still opened, when judging to open, producing alarm, and indicating which grounding car to be in abnormal condition.
Compared with prior art, the beneficial effects of the utility model are, on the one hand, after left shell and right shell body close, by laying, contact is wrapped up closely, thus play dust-proof, and may expose in atmosphere less, thus reach anti-oxidation, moistureproof, on the other hand, in magnetic key operated lock, auxiliary contact and contact switch are conveniently set, they may be used for a kind of transformer station high-voltage earthing handcart supervisory control system, thus solve effective management and the supervision problem of high-voltage earthing handcart, prevent security incident.
