Shockproof off-ground high-voltage switch cabinet mechanism

Abstract

The invention discloses a shockproof off-ground type high-voltage switch cabinet mechanism. The mechanism comprises a bottom plate, the upper end of the bottom plate is fixedly connected with a shockproof layer; the top end of the shockproof layer is fixedly connected with a supporting plate; a first hydraulic cylinder is arranged on the supporting plate; a second hydraulic cylinder is arranged atthe corresponding position of the right side of the first hydraulic cylinder, a third hydraulic cylinder is arranged at the corresponding position of the rear side of the second hydraulic cylinder; afourth hydraulic cylinder is arranged at the corresponding position of the left side of the third hydraulic cylinder, a piston rod is arranged at the top end of the first hydraulic cylinder, a case is fixedly connected to the top end of the piston rod, the four corners of the case are fixedly connected to one ends of connecting rods, and the other ends of the connecting rods are fixedly connectedto telescopic rods. According to the cabinet mechanism, the shockproof effect of the whole mechanism is achieved by arranging the shockproof layer, a computer case can be lifted to a proper positionby arranging the hydraulic cylinder, ground moisture corrosion is prevented by arranging a ground-off mode, meanwhile, bottom surface heat dissipation is improved, and the computer case is worthy of vigorous popularization.

[0002] High-voltage switchgear refers to the role of on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption. High-voltage switchgear is used as Shanghai Eaton general equipment network cabinet (HXGN type), etc. Electrical products with voltage levels ranging from 3.6kV to 550kV, high-voltage isolating switches and grounding switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof power distribution devices and high-voltage switchgears, etc., are mainly applicable In various occasions such as power plants, substations, petrochemicals, metallurgical steel rolling, light industry textiles, factories and mines, residential quarters, high-rise buildings, etc., attention should be paid to the vacuum circuit breaker trolley in the high-voltage switchgear after closing the switch at the test position. , the trolley circuit breaker cannot enter the working position to prevent closing with load. When the grounding knife in the high-voltage switchgear is closed, the trolley circuit breaker cannot enter the closing position to prevent closing with the grounding wire. The vacuum circuit breaker in the high-voltage switchgear When closing the switch, the back door of the panel cabinet is locked with the machine on the grounding knife to prevent it from entering the charged interval by mistake. The vacuum circuit breaker in the high-voltage switch cabinet is closed when it is working, and the grounding knife cannot be put in to prevent the live connection from being connected to the ground. When the vacuum circuit breaker in the line and voltage switch cabinet is working and closing, it cannot exit the working position of the trolley circuit breaker, preventing the load from pulling the switch

[0003] Most of the existing high-voltage switchgears are floor-standing. The floor-standing type is easy to corrode the high-voltage switchgear due to the wet ground. It is not convenient for personnel to observe and the bottom cannot dissipate heat. Anti-shock effect, the vibration generated by the surrounding machines is easy to cause vibration to the structure in the cabinet, reducing the service life of the parts inside the cabinet
