Interval embedding type combined insulation device for 10 KV ring main unit

Abstract

The invention discloses an interval embedding type combined insulation device for a 10 KV ring main unit. The insulation device is embedded in the ring main unit and comprises a fixing frame horizontally arranged in the ring main unit, and a shielding hood embedded in the ring main unit and clamped on the fixing frame. The shielding hood comprises a shielding hood body, flangings are arranged on the periphery of the outer end face of the shielding hood body, clamping openings are formed in the inner end face of the shielding hood body, and the clamping openings are clamped on the fixing frame. Rib plates are symmetrically arranged at the inner bottom of the shielding hood body, and stabilizing plates are connected to the two side edges of the shielding hood body. The interval embedding type combined insulation device solves the problems that in non-power-off operation of cables, internal interval space of the ring main unit is narrow, and in electrified wiring operation, safety distance is not enough; boxes which are grounded at intervals and electrified terminals in the ring main unit are effectively insulated and isolated, and electrical accidents in non-power-off wiring operation are avoided.

Description

technical field [0001] The invention relates to an electrical insulation device, in particular to a 10KV ring network cabinet embedded composite insulation device at intervals. Background technique [0002] Carrying out cable non-stop operation is the need for the development of urban power grids, and it is the most effective and direct way to improve the reliability of power supply. As an extension of power distribution live work, the electrical wiring of the internal interval of the ring network cabinet is involved in the operation of the cable without power failure. The ring network cabinet is an extremely important device in the cable line. It is very easy to cause an electrical accident of single-phase grounding when wiring without power failure. Contents of the invention [0003] The purpose of the present invention is to provide a 10KV ring network cabinet interval embedded combined insulation device, which solves the problem that the internal interval space of the...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a 10KV ring network cabinet interval embedded combined insulation device, which solves the problem that the internal interval space of the "ring network cabinet" is small when the cable is not powered off, and the safety distance is insufficient when the electrical wiring is carried out with electricity. The internally spaced grounded box and the live terminals are effectively insulated and isolated, so as to avoid electrical accidents during non-stop wiring
