Abstract
The utility model relates to the technical field of power distribution cabinets, specifically to a fixed AC metal closed switching device. The device comprises a bus-bar room, a pressure release channel, a meter cabinet, an interlocking mechanism, a master switch gear room, an electromagnetic spring mechanism, a ground bus and a cable chamber. The pressure release channel is arranged between the bus-bar room and the meter cabinet. The bottom of the meter cabinet is provided with the interlocking mechanism which is connected with the master switch gear room. The bottom of the master switch gear room is provided with the electromagnetic spring mechanism which is connected with the ground bus. The bottom of the master switch gear room is provided with the cable chamber. If inner arcing happens, a gas can pass through the pressure release channel to release the pressure. A support insulator in the cable chamber can be provided with a voltage monitoring device. In order to prevent disconnection and connection of a disconnecting switch with load, prevent disconnection and connection errors of an open circuit, prevent inadvertent entry of an electrified spacing, prevent live connection of an earthing switch and prevent live earthing knife-switch switch-on in the interlocking mechanism, a switch cabinet adopts a corresponding interlocking mechanism, leading to a very good effect.
Description
Technical field
The utility model relates to power distribution cabinet technical field, specifically a kind of fixed AC metal closed switching device.
Background technology
Fixed AC metal closed switching device is 3.6～12kV, three-phase alternating current 50Hz for rated voltage, the electric power of current ratings 630～3150A, in system, conduct is accepted and the use of distributing electric energy, be specially adapted to the occasion of frequent operation, its bus-bar system be single busbar connection, can the band bypass of derivation place single busbar connection and double-bus configuration system, existing switching device is without pressure relief channels, when if internal arc occurs, gas cannot discharge, easily cause security incident, existing switching device does not have monitoring arrangement, has potential safety hazard.
Therefore, if while designing internal arc generation for overcoming the deficiency of above-mentioned technology, gas can be by pressure relief channels by earth pressure release, in cable vault, supporting insulator can be provided with voltage monitoring device, interlocking device is in order to prevent on-load deciliter isolating switch, prevent mistake minute mistake make and break road, prevent mistakenly entering charged chamber; Prevent that band from closing earthed switch; Prevent from being with earthing to close a floodgate, switch cubicle adopts a kind of fixed AC metal closed switching device of corresponding interlocking device, just inventor's problem to be solved.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of fixed AC metal closed switching device, it is simple in structure, easy to use, if when internal arc occurs, gas can be by pressure relief channels by earth pressure release, in cable vault, supporting insulator can be provided with voltage monitoring device, interlocking device, in order to prevent on-load deciliter isolating switch, prevents mistake minute mistake make and break road, prevents mistakenly entering charged chamber; Prevent that band from closing earthed switch; Prevent from being with earthing to close a floodgate, switch cubicle adopts corresponding interlocking device, has extraordinary practical value.
The utility model solves the technical scheme that its technical problem adopts: a kind of fixed AC metal closed switching device, it is characterized in that: device comprises bus-bar room, pressure relief channels, control room, interlocking device, main switch chamber, electromagnetic spring mechanism, earth bus, cable vault, in the middle of bus-bar room and control room, be provided with pressure relief channels, bottom, control room is provided with interlocking device, interlocking device is connected with main switch chamber, bottom, main switch chamber is provided with electromagnetic spring mechanism, electromagnetic spring mechanism is connected with earth bus, bottom, main switch chamber is provided with cable vault.
The beneficial effects of the utility model are:
When 1, if the utility model internal arc occurs, gas can be by pressure relief channels by earth pressure release, and in cable vault, supporting insulator can be provided with voltage monitoring device, and interlocking gear is in order to prevent on-load deciliter isolating switch, prevent mistake minute mistake make and break road, prevent mistakenly entering charged chamber; Prevent that band from closing earthed switch; Prevent from being with earthing to close a floodgate, switch cubicle adopts corresponding interlocking device, has extraordinary effect.
