Abstract
The invention provides an environment-friendly medium-pressure gas insulation switch cabinet. A low-pressure compartment and an inflation compartment are installed in a cabinet body. The environment-friendly medium-pressure gas insulation switch cabinet is characterized in that the inflation compartment is a sealed box, a main bus and a grounding switch are installed in the inflation compartment, the main bus is connected with a three-station load and a fuse, one end of the fuse is connected with the grounding switch, the other end of the fuse is connected with a control mechanism through a cable, the grounding switch is also connected with a cable socket which is connected with a cable plug, and a pressure release plate is installed at the lower end of the inflation compartment. By means of an insulation shell, the inflation compartment is arranged as the sealed box, the main bus, the grounding switch and the three-station load inside the inflation compartment are installed in the insulation sealed box, insulating strength inside the inflation compartment is enhanced, the switch cabinet is compact in structure, and manufacturing and maintaining cost of the switch cabinet is effectively lowered. The environment-friendly medium-pressure gas insulation switch cabinet has the excellent advantages of being small in size, environment-friendly, safe, low in maintenance frequency, high in reliability and the like.
Description
Technical field
The invention belongs to high pressure equipment for power transmission and distribution technical field, relate in particular to a kind of gas insulation switch cabinet.
Background technology
Gas insulation switch cabinet is a kind of gas isolated switch cubicle that utilizes, and its substantive characteristics is primary element to be sealed in be filled with the low pressure gas dielectric and (adopt SF usually
6, N
2And SF
6Gaseous mixture, N
2Deng) casing in, be not subjected to the influence of external environment condition, its outstanding advantage is the operation of product miniaturization whole day, reliability height, safe, more and more admitted by the domestic user, but domestic design to gas insulation switch cabinet at present, manufacturing still are in the starting stage, although the gas insulation switch cabinet of existing many enterprises still has many product long-time running reliability problems that influence to need to be resolved hurrily, especially SF by type approval test
6Have greenhouse effect, if control is improper, cause this gas leak, will exert an influence to environment, be unfavorable for the feature of environmental protection of product.
Patent CN201113292 provides a kind of gas-insulated vacuum looped network switch cubicle, comprise the isolating switch that is arranged in the switch gear room, the switch gear room is a seal case, in seal case, be provided with an insulation shell, isolating switch and connected vacuum interrupter are arranged in the insulation shell, though this patent is simple in structure, only improve the dielectric strength of switch gear room by Merlon insulation shell parcel isolating switch and vacuum interrupter, with low content of technology, effect is unsatisfactory.Also there is the dry air of employing to replace SF in the prior art
6As dielectric, though air is harmless, the very easily conduction of making moist is unfavorable for the safe handling of equipment.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the invention provides the environment-friendly type medium pressure gas insulated switch cabinet that a kind of compact conformation, anti-leak performance are good, environment do not had harm.
The present invention is that the technical scheme of taking that achieves the above object is:
A kind of environment-friendly type medium pressure gas insulated switch cabinet, comprise cabinet, be provided with low-voltage compartment and charging compartment in the described cabinet, described charging compartment is positioned at the cabinet middle part, charging compartment separates by insulation shell and low-voltage compartment, it is characterized in that charging compartment is seal case, be provided with main bus bar and earthed switch in it, described main bus bar is connected with three-stations load switch, the main bus bar lower end is connected with fuse, described fuse one end is connected with earthed switch, the fuse other end is positioned at low-voltage compartment, and is connected with controlling organization by cable, and described earthed switch also is connected with cable socket, described cable socket is connected with the cable plug that is positioned at low-voltage compartment, and the charging compartment lower end is provided with pressure releasing plate.
Described cable socket is male-tapered.
Beneficial effect of the present invention is: charging compartment is arranged to seal case by insulation shell, and in the insulated enclosure case with the main bus bar in the plenum chamber, earthed switch and three-stations load switch setting, thereby improved the dielectric strength in the plenum chamber, make the switch cubicle compact conformation, reduced the floor space of switch cubicle, thereby effectively reduced manufacturing and the maintenance cost of switch cubicle; Three-stations load switch can be realized connection, isolation and grounding function simultaneously, and is easy to operate; Pressure releasing plate prevents in the switch cubicle that gas pressure is excessive and cabinet is damaged.Star's advantages such as the present invention has that size is little, environmental protection, safety, maintenance frequency are low, reliability height.
