Description

Technical Field

[0001] This utility model relates to the field of disconnecting switch technology, and in particular to a disconnecting switch installation structure. Background Technology

[0002] Disconnect switches, also known as knife switches, usually refer to high-voltage disconnect switches. They are switching devices that can carry current under normal circuit conditions and current under abnormal conditions (such as short circuits) within a specified time. They are very common in outdoor high-voltage line installations, and their working principle and structure are relatively simple.

[0003] Currently, because the ceramic resistors used in disconnect switches are hollow inside and are installed outdoors on high-voltage line racks, water easily accumulates inside during rainy weather, which reduces their service life and causes corrosion at the connection points, making subsequent maintenance inconvenient. Utility Model Content

[0004] To address the problems in the prior art, this utility model provides an installation structure for a disconnecting switch. The basic concept of the technical solution adopted by this utility model to solve the aforementioned technical problems is as follows:

[0005] A disconnector mounting structure includes an aluminum alloy plate. Ceramic resistors are disposed on the top of the aluminum alloy plate near both side edges. A bridging ring is fixed to the top of each ceramic resistor. The interior of each ceramic resistor is hollow. An insulating screw is disposed inside each ceramic resistor. The top of each insulating screw slides through to the top of the ceramic resistor. A cover plate is fixed to the top of each insulating screw.

[0006] Optionally, a sealing ring is provided at the bottom of both cover plates near the outer edge, and a sealing groove is provided at the bottom of both sealing rings near the inner edge.

[0007] Optionally, a sealing ring is fixed to the top of each of the two ceramic resistors near the inner edge, and the two sealing rings are respectively engaged inside the sealing groove.

[0008] Optionally, the bottoms of both sealing rings are in contact with the top of the ceramic resistor, and the outer surfaces of both insulating screws are fixed with limiting rings, which are slidably connected between the inner walls of the ceramic resistor.

[0009] Optionally, the bottoms of both insulating screws slide through to the bottom of the aluminum alloy plate, and locking nuts are threaded onto the outer surfaces of both insulating screws near the bottom edge, with the tops of both locking nuts corresponding to and abutting the bottom of the aluminum alloy plate.

[0010] Optionally, an insulating buffer pad is provided between the bottom of the two ceramic resistors and the top of the aluminum alloy plate, and multiple side openings are provided on the outer surface of the two bridging rings near the bottom edge.

[0011] Optionally, a copper sleeve is fixed on one side of each of the two bridging rings, a knife plate is provided between the two copper sleeves, and a copper rod is fixed on the other side of each of the two copper sleeves.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0013] 1. In this utility model, the ceramic resistor is installed on the aluminum alloy plate using an insulating screw and a locking nut. During installation, the bottom of the insulating screw is first inserted through the bottom of the aluminum alloy plate, and then the insulating screw is pulled down by the locking nut to lock it. When the insulating screw slides down, it will drive the top cover plate to slide towards the top of the ceramic resistor, so that the sealing ring and the top of the ceramic resistor are in contact with each other, thereby making the sealing ring engage inside the sealing groove, so that the joint between the top of the ceramic resistor and the sealing ring forms a seal, preventing water from accumulating inside the top bridging ring and entering the interior of the ceramic resistor.

[0014] 2. In this utility model, during rainy weather, rainwater will hit the top of the cover plate and then enter the connection between the bridging ring and the top of the ceramic resistor. Under the sealing effect of the sealing ring and the sealing groove, the rainwater cannot enter the interior of the ceramic resistor and will flow out from the side opening at the bottom of the bridging ring to the outside, thus avoiding accumulation inside.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Example 1, as Figure 1-4 As shown, this utility model provides a technical solution for the installation structure of a disconnecting switch: it includes an aluminum alloy plate 1, ceramic resistors 2 are provided on the top of the aluminum alloy plate 1 near the two side edges, bridging rings 5 ​​are fixed on the top of the two ceramic resistors 2, the interior of the two ceramic resistors 2 is hollow, and insulating screws 7 are provided inside the two ceramic resistors 2. The top of the insulating screws 7 slides through to the top of the ceramic resistors 2, and a cover plate 12 is fixed on the top of the two insulating screws 7. A sealing ring 13 is provided on the bottom of the two cover plates 12 near the outer surface edge, and a sealing groove 14 is opened on the bottom of the two sealing rings 13 near the inner edge. A sealing ring 15 is fixed on the top of the two ceramic resistors 2 near the inner edge, and the two sealing rings 15 are correspondingly engaged inside the sealing groove 14.

[0025] The effect achieved by the entire embodiment 1 is that the ceramic resistor 2 is installed on the aluminum alloy plate 1 by means of the insulating screw 7 and the locking nut 8. During installation, the bottom of the insulating screw 7 is first inserted through to the bottom of the aluminum alloy plate 1, and then the insulating screw 7 is pulled down by the locking nut 8 to lock it. When the insulating screw 7 slides down, it will drive the top cover plate 12 to slide towards the top of the ceramic resistor 2, so that the sealing ring 13 and the top of the ceramic resistor 2 are in contact with each other, and the sealing ring 15 is locked inside the sealing groove 14, so that the joint between the top of the ceramic resistor 2 and the sealing ring 13 forms a seal, preventing water from accumulating inside the top bridging ring 5 and entering the interior of the ceramic resistor 2.

[0026] Example 2, as Figure 1-4As shown, the bottoms of the two sealing rings 13 are in contact with the tops of the ceramic resistor 2. The outer surfaces of the two insulating screws 7 are fixed with limit rings 9. The two limit rings 9 are slidably connected between the inner walls of the ceramic resistor 2. The bottoms of the two insulating screws 7 slide through to the bottom of the aluminum alloy plate 1. The outer surfaces of the two insulating screws 7 are threaded with locking nuts 8 near the bottom edge. The tops of the two locking nuts 8 are in contact with the bottom of the aluminum alloy plate 1. An insulating buffer pad 10 is provided between the bottoms of the two ceramic resistors 2 and the tops of the aluminum alloy plate 1. The outer surfaces of the two bridging rings 5 ​​are provided with multiple side openings 11 near the bottom edge. A copper sleeve 3 is fixed on one side of the two bridging rings 5. A knife plate 6 is provided between the two copper sleeves 3. A copper rod 4 is fixed on the other side of the two copper sleeves 3.

[0027] The effect achieved by the entire embodiment 2 is that, in rainy weather, rainwater will hit the top of the cover plate 12 and then enter the connection between the bridging ring 5 and the top of the ceramic resistor 2. Under the sealing effect of the sealing ring 15 and the sealing groove 14, the rainwater cannot enter the interior of the ceramic resistor 2 and will flow out from the side opening 11 at the bottom of the bridging ring 5 to the outside, thus avoiding accumulation inside.

[0028] Working principle: The ceramic resistor 2 is installed on the aluminum alloy plate 1 using the insulating screw 7 and the locking nut 8. During installation, the bottom of the insulating screw 7 is first inserted through the bottom of the aluminum alloy plate 1, and then the insulating screw 7 is pulled down by the locking nut 8 to lock it. When the insulating screw 7 slides down, it will drive the top cover plate 12 to slide towards the top of the ceramic resistor 2, so that the sealing ring 13 and the top of the ceramic resistor 2 are in contact with each other, and the sealing ring 15 is locked inside the sealing groove 14, so that the joint between the top of the ceramic resistor 2 and the sealing ring 13 forms a seal, preventing water from accumulating inside the top bridging ring 5 and entering the interior of the ceramic resistor 2. In rainy weather, rainwater will hit the top of the cover plate 12 and then enter the connection between the bridging ring 5 and the top of the ceramic resistor 2. Under the sealing effect of the sealing ring 15 and the sealing groove 14, the rainwater cannot enter the interior of the ceramic resistor 2 and will flow out from the side opening 11 at the bottom of the bridging ring 5 to the outside, avoiding accumulation inside.
