Description
Technical field
The utility model relates to a kind of box-shaped fixed type alternating current metal closed switch, belongs to high-tension switch cabinet equipment technical field.
Background technology
The box-shaped fixed type alternating current metal closed switch used at present is the most frequently used indoor complete power distribution equipment; the electric energy of extensive use three-phase alternating current electric power system can introduce and distribute and export and simultaneously can play the effects such as protection, monitoring to circuit; carry out for guaranteeing that power supply safety is stable, its inside often needs to install multiple stage electric components equipment.In order to ensure each electric components stable equipment operation and air insulation performance, electric components in casing between minimum range be not less than 300 millimeters, thus it is excessive to cause body structure, current box house does not possess necessary measure such as dust-proof grade simultaneously, easily cause electric components to cause the phenomenons such as electric leakage because of dust etc., thus cause serious equipment fault.Therefore need to carry out scientific and reasonable again designing to overcome in current use the numerous deficiencies existed to the box-shaped fixed type alternating current metal closed switch structure of current use.
Utility model content
For the deficiency that prior art exists, the utility model provides a kind of box-shaped fixed type alternating current metal closed switch.This utility model comparatively conventional switching devices, simple and compact for structure, dust-proof and good insulation preformance, volume and conduct oneself with dignity little, improve on the one hand greatly installation and the turn-over capacity of switchgear, also contribute on the other hand improving stable equipment operation and reliability, extension device useful life.
To achieve these goals, the utility model realizes by the following technical solutions:
A kind of box-shaped fixed type alternating current metal closed switch, comprises casing.Establish dividing plate in casing and by dividing plate, box house be divided into hyperbaric chamber and relay monitoring and protection room.Dividing plate separately establishes open-work.Separately between hyperbaric chamber and relay monitoring and protection room be communicated with by line emissions groove and establish bus bar in line emissions groove.Separately between bus bar to be isolated by rigid insulation block and distance between bus bar is not less than 5 millimeters.Establish circuit breaker, upper isolating switch, lower isolating switch, earthed switch, current transformer, main bus bar and branch bar in hyperbaric chamber and separately establish elastic insulated separator between circuit breaker, upper isolating switch, lower isolating switch, earthed switch, current transformer, main bus bar and branch bar.Relay, monitoring device and indicator light are separately established in relay monitoring and protection indoor.Monitoring device and indicator light are separately embedded in box outer surface.Bottom half separately establishes at least 3 cable-through holes.Hyperbaric chamber and relay monitoring and protection indoor box body inner surface separately to be set up defences dust hood and lighting lamp group.Box outer surface separately establishes operating mechanism.Operating mechanism is separately connected with upper isolating switch, lower isolating switch and earthed switch respectively by connecting rod.
Further, described lighting lamp group is light-emitting diode.
Further, described cable-through hole separately establishes spring protective cover.
The utility model is conventional switching devices comparatively, simple and compact for structure, dust-proof and good insulation preformance, volume and conduct oneself with dignity little, improve on the one hand greatly installation and the turn-over capacity of switchgear, also contribute on the other hand improving stable equipment operation and reliability, extension device useful life.
