Box-type alternating-current metal-enclosed switchgear

Abstract

The invention discloses a box-type AC metal-enclosed switchgear, which comprises a device main body, and the device main body comprises a box body, a box door, a heat dissipation device, a wall bushing, a heat dissipation port, an operation block, a grounding switch, a wire breaker and a bus chamber. One side of the box body is connected with a box door, an observation window is arranged above the box door, a heat dissipation device is arranged below the observation window, a wall bushing is arranged behind the box body, a heat dissipation opening is formed below the wall bushing, and the heat dissipation opening is connected with the back face of the box body. The device body has the advantages of being high in grade, small in size, low in price, little in maintenance, convenient to operate and the like, meanwhile, the device body can conveniently observe the situation in the box through the observation window, operation is convenient, and the complexity degree of the early stage of overhauling when faults occur is reduced.

Description

technical field [0001] The invention relates to the technical field of electric power machinery, in particular to a box-type AC metal-enclosed switchgear. Background technique [0002] The AC metal-enclosed switchgear is a new generation of medium-voltage electrical products that has been successfully designed and successfully developed by introducing advanced technology and in accordance with the domestic rural power and area network transformation requirements. After strict type test and long-term operation assessment, all technical performance indicators have reached IEC298 and GB3906 standards. It has the remarkable characteristics of small size, light weight, beautiful appearance, easy operation, long life, high parameters, no pollution, and less maintenance. [0003] With the development of the industrial field, the existing AC metal-enclosed switchgear is not very convenient to use due to the lack of necessary preventive structures, and the internal environmental con...
