Background technology
In electric power system, intermediate switchgear cabinet is because the handcart volume is little, and interchangeability is good, and possesses perfect, reliable anti-misoperation function, thereby is widely used in power distribution network.But when the bus in switch cubicle needs interruption maintenance, according to the power safety regulation, must first to the bus in switch cubicle, carry out the electrical verification operation, identify without just allowing the installing earth connection after electricity, then bus be carried out to service work.But existing electrical verification mode normally, with the high voltage electroscope with certain-length, directly contacts or approaches charging equipment, to report to the police and determine that equipment has no-voltage by sound, light, this electrical verification mode is only applicable to the open type switch cubicle.Therefore if adopt conventional electrical verification mode not by equipment, with the hands push valve in intermediate switchgear cabinet open to the bus electrical verification, because of can not meet power safety to safe distance requirement be easy to slip up because of staff's electrical verification, cause great human casualty accident.At present also there is special-purpose grounding apparatus to be developed use, as " a kind of grounding car with adjustable height of center-set switching device " of application number 200920075234.7, though can complete the ground connection of bus, can not electrical verification.In addition, used earthing clamp is because of the pattern reason of bus static contact structure, can only utilize the space between fixed contact and contact box, plug is in centre, very easily little because of extruding force or vibrations loose or dislocation, cause to connect unreliablely, therefore need a kind of electrical verification, ground connection process to meet the power safety regulation, can to bus in intermediate switchgear cabinet carry out electrical verification ground connection the electrical verification grounding apparatus.
Summary of the invention
The purpose of this utility model is to carry arch intermediate switchgear cabinet bus electrical verification grounding car, solve the safety related technical problems that the sealing intermediate switchgear cabinet exists in bus electrical verification and ground connection operating process, can be convenient to use general high voltage electroscope, whether chargedly directly identify bus, and can utilize the convenient and reliable ground connection of earth rod, guarantee operation personnel's safety.
The utility model is achieved in that intermediate switchgear cabinet bus electrical verification grounding car comprises chassis vehicle, three poles and contact arm, and contact arm is arranged on the upper end of pole, and its front end is equipped with the bus contact, and the corresponding contact arm of each pole is installed grounding contact at opposite side.Pedestal, valve unlatching guide plate and insulating barrier also are housed on chassis vehicle, and insulating barrier is fixed on the lateral surface of pedestal, and valve unlatching guide plate is equipped with in the front end both sides of pedestal.
Compared with prior art the utility model has the advantage of: simple in structure, handling safety, convenience, can be to the direct electrical verification of general high voltage electroscope for bus, and realize reliable ground by earth rod and grounding contact, electrical verification and the ground connection of bus in the sealing intermediate switchgear cabinet have been realized, guarantee staff's handling safety, there is obvious economic benefit and social benefit.
