Abstract

The invention provides a fixed metal-enclosed switch cabinet, relating to the field of power distribution equipment. The fixed metal-enclosed switch cabinet comprises a casing, a switch device is fixedly mounted on the bottom of an inner wall of the casing, an insulating plate is fixedly mounted on two sides of the switch device, heat dissipation holes penetrating through the casing are formed ontwo sides of the casing and on the lower side of the casing, two moisture-proof pipes are fixedly mounted on a back side of the inner wall of the casing and on an upper side of the switch cabinet, anda clamp ring is annularly arranged at the interior of the moisture-proof pipe . According to the fixed metal-enclosed switch cabinet, the pressure of the cabinet is released to the interior of a topcover through the ventilation pipeline by the combination of a pressure relief hole and a straight groove, then the pressure inside the top cover is released to the outside of the cabinet by the combination of a slide bar and an iron piece, it can function in pressure relief to avoid exploding caused by over large pressure inside the cabinet and brings great convenience to people.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment, in particular to a fixed metal-enclosed switchgear. Background technique [0002] The fixed metal-enclosed switchgear is also called the ring network cabinet. The ring network cabinet is a set of high-voltage switchgear installed in the steel plate metal cabinet or made into an assembled interval ring network power supply unit. Its core part adopts load switches and fuses. device. [0003] For example, the Chinese patent discloses a "comprehensive ring network cabinet" (patent number: CN204927827U), which includes a cabinet body, a switch, an operating tool, a fixing buckle, a transparent plate and a test hole. The above-mentioned patents can confirm the live state of each equipment in the ring network cabinet in advance to avoid safety accidents when maintenance personnel overhaul, and are equipped with operating tools to bring convenience to maintenance personnel, but as t...
