Partition plate device for separating ring network box body from inspection well and installation method of partition plate device

Abstract

The invention discloses a partition plate device for separating a ring network box body from an inspection well. The partition plate device comprises a moisture-proof partition plate main body, wherein clamping grooves are formed in the circumferential side wall of the moisture-proof partition plate main body, expansion bolts are arranged on the multiple clamping grooves, two sealing strips are arranged on the side walls of the multiple clamping grooves, flow guide grooves are formed in the multiple clamping grooves, water drainage holes are formed in the multiple flow guide grooves, two wire inlet holes are formed in the side wall of the moisture-proof partition plate body, and four wire outlet holes are formed in the side wall of the moisture-proof partition plate body. The invention further discloses an installation method of the partition plate device. The method comprises the following steps of firstly, taking down a shutter at the top of a ring network box foundation well, enabling the power cable to penetrate into the ring network box foundation well from the plurality of wire inlet holes and penetrate out of the ring network box foundation well from the plurality of wire outlet holes, and finally installing the shutter at the top of the ring network box foundation well. The partition plate device has double effects of preventing water vapor in the foundation well from entering the ring network box and preventing equipment faults from diffusing into the foundation well to influence other power supply lines, and can improve the power supply reliability.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a partition plate device for separating a ring net box and an inspection well and an installation method thereof. Background technique [0002] General ring cage equipment is more suitable for normal operation in an environment with a relative humidity of 40% to 60%. When the relative humidity exceeds 80%, moisture will have an adverse effect on the equipment. One is the hazard of electrochemical corrosion. Each metal has a critical relative humidity, and its value is between 50% and 80%. When the humidity reaches the critical relative humidity, an adsorbed electrolyte film will be formed on the surface of the metal. Metals switch from chemical corrosion to electrochemical corrosion. Corrosion capability is greatly enhanced due to the altered corrosive properties. When the air contains pollutants and the humidity exceeds 80%, the corrosion rate is greatly acce...

AI Technical Summary

Problems solved by technology

When the air contains pollutants and the humidity exceeds 80%, the corrosion rate is greatly accelerated, which will seriously damage the equipment components

Second, the hazards of ozone

[0003] The harsh humid and hot environment can easily lead to condensation or even water accumulation on the surface of electrical equipment, severe insulation performance degradation, corrosion damage and serious failures

Because the depth of the inspection well at the bottom of the ring network cabinet is about 2 meters, the equipment that has been in operation for one year will be full of water drops at the three-way point of the lower cable and the lower bottom plate, and the iron bottom plate is already rusty. Due to the poor seal of the cable outlet, the cable and SF6 The switch joint is very humid, and the cable fastening screws are rusted. In order to prolong the service life of the ring network cabinet, it is urgent to prevent moisture and dehumidify the bottom of the ring network cabinet
