Description

Technical Field

[0001] The present application relates to the technical field of rainproof equipment, and in particular to a rainproof cover for a pressure relief valve. Background Art

[0002] As we all know, the pressure relief valve is connected to the transformer. Its main function is: when the internal pressure of the transformer increases, the pressure relief valve sprays oil to relieve the pressure of the transformer and prevent the transformer box from being damaged due to excessive internal pressure.

[0003] At present, since the pressure relief valve is a location that operating personnel frequently inspect, they need to understand the internal changes of the transformer by observing the working status of the pressure relief valve. Therefore, the pressure relief valve is exposed to the outside, so that the connection between the pressure relief valve and the cable is exposed. It is easy to get damp in rainy weather, and the cable is very likely to be grounded, affecting equipment operation and increasing maintenance costs.

[0004] Therefore, in view of the above-mentioned related technologies, it is necessary to install a protective cover on the outside of the pressure relief valve installed outdoors to prevent rain and sun exposure, so as to ensure the normal use of the pressure relief valve. Utility Model Content
