Dustproof all-insulation load ring main unit

Abstract

The invention discloses a dustproof all-insulation load ring main unit. The dustproof all-insulation load ring main unit comprises a first cabinet body and a second cabinet body; the second cabinet body is fixed to the rear side of the first cabinet body; a first protective door is hinged to the upper portion of the front surface of the first cabinet body; a display meter and a second handle are installed on the front surface of the first protective door; and the second protective door is hinged to the side, located on the first protective door, of the front surface of the first cabinet body.According to the dustproof all-insulation load ring main unit of the invention, through a designed dustproof mechanism, a dustproof net is stably inserted, a dustproof effect is achieved, protection on components is improved, and the service lives of the components are prolonged; when dust adsorbed to the surface of the dustproof net blocks heat dissipation, the dustproof net can be conveniently pulled out to be cleaned; through a designed guide mechanism, a top frame is rapidly stabilized on the second cabinet body, and therefore, the connection guide of the top frame and the second cabinet body is improved, bolts can conveniently penetrate through bolt holes in the surfaces of the top frame and the second cabinet body, and the fixing efficiency of the top frame and the second cabinet body is improved.

Description

technical field [0001] The invention belongs to the technical field of ring network cabinets, and in particular relates to a dustproof fully insulating load ring network cabinet. Background technique [0002] The ring network cabinet is a group of transmission and distribution electrical equipment (high-voltage switchgear) installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. It has a structure Simple, small size, low price, can improve power supply parameters and performance, and power supply security and other advantages. It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises. [0003] The existing full insulation load ring main unit has the following deficiencies when used: [0004] 1. There are deficiencies in dust resistance, w...
