Description

Background technique

With the rapid development of high-voltage power equipment technology in my country, GIS equipment has been widely used in high-voltage power systems, but the GIS equipment has the following problems in actual use:

Since the sunken CT junction box of GIS equipment is generally equipped with an integrated welded metal cable inlet tube for wiring, the integrated welded metal cable inlet tube will pass the moisture in the cable trench through the "chimney effect". "A large number of them are brought into the GIS sunken CT junction box. After a long time, the moisture is very easy to condense or even accumulate water in the GIS sunken CT junction box, which will cause "insulation reduction" and "terminal short circuit" to the CT secondary circuit.

At present, in order to solve the problem of moisture in the GIS sunken CT junction box, the physical means of dehumidification agent is generally used to drive the moisture. Specifically, the bottom plate of the CT junction box is removed first, and then the moisture-repellent is placed on the bottom plate of the CT junction box. Finally, reset and install the bottom plate of the CT junction box with moisture repellant. Although this tide-repelling method can play a role in tide-repelling, because the service life of the tide-repelling agent is generally only about 3 days, it is difficult to meet the tide-repelling needs under the condition of large tidal volume on site.
