Description

Technical Field

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

[0002] The transformer gas relay is a protective device used in transformers. It is installed in the pipeline between the oil storage cabinet and the oil tank of the transformer. When the internal fault of the transformer causes the oil to decompose and produce gas or causes oil flow surge, the contacts of the gas relay are activated, the designated control circuit is connected, and a signal alarm is promptly issued (light gas) or the protection element is activated to automatically cut off the transformer (heavy gas). The side wall of the gas relay is provided with a visual window glass to facilitate the observation of changes in the liquid level capacity in the cavity.

[0003] Gas relays are usually installed outdoors. When it rains or when snow melts, water drops can easily drip into the junction box through the oil pillow, which can cause a ground fault at best. In worst cases, the transformer protection may mistakenly send a light gas signal or even a heavy gas protection action, causing switches on both sides of the transformer to operate, resulting in a power outage. In order to prevent water from entering, a rain cover is usually installed on the gas relay. However, the rain covers currently available on the market have a simple structure and cannot effectively prevent rainwater from entering. They are also poor in dust prevention, which affects the service life of the gas relay. Utility Model Content

[0023] Example:

[0024] Reference Figure 1-Figure 4A protective device for a gas relay comprises a lower shell 1, and also comprises: an upper shell 2, which is plugged and connected with the lower shell 1, and an insertion end 104 is fixedly arranged on the lower shell 1, and the inner wall of the upper shell 2 is against the outer wall of the insertion end 104. When in use, on the one hand, it can ensure that the position of the upper shell 2 on the lower shell 1 is fixed and reliable, and prevent the upper shell 2 from being dislocated, which affects normal use. On the other hand, it can reduce the entry of rainwater from the joint between the upper shell 2 and the lower shell 1, and improve the rainproof effect. In addition, a rain shield 201 is fixedly arranged on the top of the upper shell 2, and a downwardly inclined rain shield eaves is fixedly arranged on the rain shield 201, which can further improve Rainproof effect: the connecting pipe is sleeved on the gas relay pipeline, and two groups of connecting pipes are symmetrically arranged. Rubber pads are arranged in the two groups of connecting pipes, and the inner wall of the rubber pad is pressed against the outer wall of the gas relay pipeline. When in use, the lower shell 1 is placed under the gas relay, and then the upper shell 2 is covered on the lower shell 1. At this time, the connecting pipe just covers the pipeline of the gas relay, and the outer wall and inner wall of the rubber pad are respectively pressed against the inner wall of the connecting pipe and the outer wall of the gas relay pipeline. On the one hand, it can improve the rainproof effect and reduce rainwater on the gas relay. On the other hand, it can avoid dust accumulation on the gas relay and increase the service life of the gas relay.

[0025] When in use, the gas relay is placed in the lower shell 1 and then the upper shell 2 is covered on the lower shell 1, so that the gas relay can be completely wrapped to improve the rain and dust proof effects. In addition, a first dustproof net 103 is fixedly provided on the lower shell 1, and a second dustproof net 202 is fixedly provided on the upper shell 2, so as to facilitate the heat dissipation of the gas relay and improve the use effect. By using the first pipe 3 and the second pipe 4 to wrap the pipe of the gas relay, and fixing the first pipe 3 and the second pipe 4 to the lower shell 1 and the upper shell 2 respectively, it can be prevented that rain or dust will prevent the bolts on the pipe flange of the gas relay from rusting, which will make it inconvenient to disassemble and affect the maintenance efficiency.

The assembly and disassembly is convenient, the fixing is reliable, and the maintenance efficiency can be improved.

[0028] Reference Figure 1-Figure 3 A avoidance pipe 301 is fixedly provided on the first pipe 3 and the second pipe 4. When in use, the flange of the gas relay pipe is located in the avoidance pipe 301, which can reduce rainwater or dust falling on the flange, causing the bolts on the flange to rust and increase the difficulty of subsequent disassembly.

[0029] Reference Figure 1-Figure 4 An observation window 101 is provided on the lower shell 1. The observation window 101 faces the inspection window of the gas relay. A transparent plate is fixedly arranged in the observation window 101. The transparent plate can be transparent glass or a transparent acrylic plate, preferably transparent glass. When in use, it is convenient to observe the inspection window of the gas relay through the glass. On the other hand, it can reduce the entry of dust and improve the use effect. A baffle 5 for blocking the observation window 101 is slidably arranged on the lower shell 1. A push plate 501 is fixedly arranged on the baffle 5. A slide groove 100 is provided on the lower shell 1. 2. The baffle 5 is slidably arranged in the slide groove 102, and a spring is fixedly arranged in the slide groove 102. One end of the spring away from the top of the slide groove 102 is fixedly connected to the top of the baffle 5. When in use, under the elastic force of the spring, the baffle 5 can always cover the observation window 101, which can prevent dust from falling on the glass in the rain, causing difficulty in cleaning and unclear observation. Pushing the push plate 501 upward can push the baffle 5 to slide into the slide groove 102, so as to open the observation window 101. The operation is convenient, the dustproof effect is reliable, and it is helpful to improve the use experience.
