Description

Technical Field

[0001] The utility model relates to the technical field of gas relays, in particular to a rainproof device for a gas relay. Background Art

[0002] The gas relay is the main protection element for internal faults in the transformer. It is installed on the connecting pipe connecting the oil storage cabinet and the transformer oil tank. If a minor fault occurs inside the transformer, the gas generated by the decomposition of the oil will gather in the gas chamber on the upper part of the gas relay. When the amount of accumulated gas reaches the set value, the alarm contact of the gas relay will energize and send out an alarm signal. If the oil level drops due to oil leakage in the transformer, an alarm signal will also be sent out (for imported gas relays, a trip signal will be sent out). If a serious fault occurs inside the transformer and the pressure in the oil tank rises instantaneously, an oil surge will be generated in the connecting pipeline where the gas relay is located, impacting the baffle of the gas relay. When the baffle rotates to a certain limited position, the gas relay will send out a trip signal to cut off all power supplies connected to the transformer, thereby protecting the transformer.

[0003] In the prior art, the Chinese utility model with publication number: CN219759457U discloses a gas relay rain cover, including a rainproof top plate and a support frame. The top surface of the rainproof top plate is in an arc-shaped block shape, and the top ends of the support frames are rotatably connected on both sides of the bottom surface. A storage groove is vertically opened inside the support frame, and a limiting block is slidably arranged in the storage groove. The limiting block is restricted and matched with the storage groove. When the device is not needed, the support frame and the telescopic rod can be retracted and folded on the bottom surface of the rainproof top plate, so that it is convenient to transport when carrying and save space when storing. The height of the defense top plate can be adjusted by the telescopic rod, so as to better cooperate with the gas relay and protect it from rain. The transparent rainproof film can be quickly tied to the support frame and the telescopic rod when in use to reduce rainwater intruding from the side. It can be rolled up and stored when not needed. Because the operation is simple and convenient, the installation is fast and timely, reducing the probability of water intrusion into the gas relay.

[0004] Although the rain shield in the above technical solution is quick to install, when the gas relay is in operation and rain is tilted and poured down by wind, the rain shield is not effective in blocking the rain, which may cause the main body or the outlet to be wet or damp. The insulation performance of the internal terminal blocks may be reduced due to moisture, which may cause the gas relay to malfunction or fail. Therefore, we need to propose a rainproof device for the gas relay. Utility Model Content
