[0002] The existing gas relays on outdoor transformers have the following disadvantages: Firstly, the gas relay body is exposed to the outdoor environment and subjected to prolonged exposure to sunlight and rain. This exposure can cause the paint on the body to oxidize and fade, leading to paint peeling and affecting its rust-proof performance. Secondly, the gas relay is connected to the transformer body and the transformer oil tank on both sides via plate valves. The gas relay and the plate valves are sealed with rubber gaskets; prolonged exposure to sunlight and rain will cause the seals to age, resulting in leakage at the plate valve seals.

[0024] like Figure 1-5 As shown, this utility model provides a protective structure for an outdoor transformer gas relay, including a support frame and a rainproof plate 5 connected to the top of the support frame. The rainproof plate 5 is arc-shaped. The support frame includes a screw 2 and a U-shaped support frame 1 slidably connected to both ends of the screw 2. An axial sliding limit structure is provided on the support frame 1, and a clamping structure is provided on the opposite sides of the two support frames 1.

[0025] When connecting the protective device to the gas relay, the protective device is placed on top of the gas relay. By adjusting the distance between the two support frames 1, the bottom of the U-shaped support frame 1 is used to clamp the top of the gas relay, so that the two support frames 1 can clamp the top of the gas relay. The movement of the support frame 1 is limited by the axial sliding limit structure, so as to achieve stable clamping of the gas relay by the support frame 1. The rainproof plate 5 connected to the top of the support frame 1 is used to shield the gas relay and prevent rainwater from directly hitting the gas relay. The arc-shaped rainproof plate 5 can prevent rain from accumulating on the top.

[0026] like Figure 1 and Figure 2 As shown. The support frame 1 and the rainproof plate 5 are connected by an arch 4, which fits snugly against the rainproof plate 5. A U-shaped support rail 12 is provided at the bottom of the arch 4, and the support frame 1 is horizontally slidably connected to the support rail 12. The top of the support frame 1 is in contact with the bottom surface of the arch 4. When adjusting the position of the support frame 1 for clamping, it is necessary to ensure that the support frame 1 effectively supports the rainproof plate 5. By setting the arch 4, and considering that the rainproof plate 5 is a transparent plate with limited strength, the arch 4 ensures the stability of the rainproof plate 5, and the support frame 1 effectively supports the arch 4, thereby achieving effective support of the rainproof plate 5 during the movement of the support frame 1.

[0027] like Figure 1 and Figure 2 As shown, to achieve stable support for the rainproof plate 5, the two ends of the support frame 1 are respectively distributed at the two ends of the arch 4. The U-shaped support frame 1 is used to support the two ends of the arch 4 at its top end, and to clamp the gas relay in the middle.

[0028] like Figure 2 , Figure 3 and Figure 5 As shown. The axial sliding limiting structure is a connecting cylinder 3 threadedly connected to the screw 2. The connecting cylinder 3 is embedded in the support frame 1 and is rotatably connected to the support frame 1. When adjusting the position of the support frame 1, by rotating the connecting cylinder 3, the connecting cylinder 3 drives the support frame 1 to move along the axial direction of the screw 2. After moving into position, the support frame 1 can clamp the gas relay.

[0029] like Figure 5 As shown. The support cylinder 3 includes an outer sleeve 31 and a threaded sleeve 32 coaxially fixed inside the outer sleeve 31. The end of the outer sleeve 31 is provided with a radial protrusion. The support frame 1 is connected to the middle of the outer sleeve 31. The radial protrusions at both ends of the outer sleeve 31 are respectively connected to the opposite outer walls of the support frame 1. The support cylinder 3 has a split structure. The inner threaded sleeve 32 is used to threadedly connect to the screw 2, and the outer sleeve 31 is used to connect to the support frame 1. The rotation of the outer sleeve 31 drives the threaded sleeve 32 to rotate. During the rotation of the threaded sleeve 32, the support cylinder 3 moves axially along the screw 2 as a whole, thereby driving the support frame 1 to move along the screw 2.

[0030] In a preferred embodiment of this utility model, to facilitate rotation of the outer sleeve 31, the radial protrusion at the end of the outer sleeve 31 is formed into a hexagonal prism structure. By clamping the radial protrusion with a wrench, the outer sleeve 31 can be smoothly turned to adjust the position of the support frame 1.

[0031] like Figure 3 and Figure 4 As shown. The clamping structure consists of clamping plates 7 connected to opposite sides of the two support frames 1. The clamping plates 7 are horizontally slidably connected to the support frames 1, and an elastic structure is provided between the clamping plates 7 and the support frames 1. The support frames 1 clamp the gas relay through the clamping plates 7. During the clamping process, the support frames 1 compress the elastic structure, thereby achieving clamping through the elastic force of the elastic structure. This elastic clamping method avoids rigid compression damage to the gas relay housing during the clamping process.

[0032] like Figure 4 As shown. A guide rod 6, horizontally penetrating the support frame 1, is connected to the clamping plate 7. The elastic structure is a spring 11 fitted onto the guide rod 6, located between the support frame 1 and the clamping plate 7. During clamping, pushing the clamping plate 7 compresses the spring 11, thereby clamping the gas relay.

[0033] like Figure 4As shown. A support cylinder 9 connects the guide rod 6 and the clamping plate 7. A limiting plate 10 connects the support cylinder 9 and the guide rod 6. The limiting plate 10 is located inside the support frame 1, and the support cylinder 9 is slidably connected inside the support frame 1. The spring 11 is located inside the support frame 1, and the outer diameter of the limiting plate 10 is larger than the outer diameter of the support cylinder 9. The limiting plate 10 is used to prevent the guide rod 6 from detaching from the support frame 1 and falling. At the same time, the guiding performance of the guide rod 6 and the support cylinder 9 can guide the movement of the clamping plate 7, ensuring the stability of the clamping.

[0034] like Figure 4 As shown. The clamping plate 7 is an arc-shaped plate, and the guide rods 6 are distributed at both ends and the middle of the clamping plate 7. Friction layers 8 are provided on the opposite sidewalls of both clamping plates 7, and friction patterns are provided on the friction layers 8. The friction layers 8 and friction patterns are used to increase the coefficient of friction and improve clamping stability. The arc-shaped structure of the clamping plate 7 causes deformation at both ends during clamping, providing greater clamping force to the corners of the gas relay. Utilizing the high strength at the corners of the gas relay, clamping stability is improved without causing structural damage to the gas relay.
