Description

Technical Field

[0001] The utility model relates to a sealing structure, in particular to a sealing structure used for a high-voltage busbar to penetrate, and belongs to the technical field of high-voltage busbar sealing structures. Background Art

[0002] The high-voltage bus is a conductive device used to transmit high-voltage electric energy in the power system. It mainly carries high voltage and large current. It is usually used to transmit higher voltage levels, such as 110kV, 220kV or even higher voltages to meet the power transmission needs of large power systems. In order to ensure the stability of the bus during operation and reduce the impact of external factors on the bus, it is usually necessary to set a sealing structure on the outside of the bus.

[0003] The sealing structure of the busbar mainly realizes locking and sealing by using rubber strips made of fire-resistant rubber in conjunction with an external metal frame, thereby realizing the fireproof sealing function of the large-diameter penetration of the high-voltage busbar. However, in real life, we can understand that the rubber strips will age during long-term use, thereby reducing the sealing effect of the busbar. Therefore, people need to replace the rubber strips after using them for a period of time. However, in the existing sealing structure technology, screws are usually used to fix the two sealing rings. This fixing method cannot meet people's needs for quick replacement of rubber strips. At the same time, the screws are exposed to the outside air for a long time and are prone to rust, which makes it difficult for people to remove the screws.

[0004] Therefore, a sealing structure for high-voltage busbar penetration is proposed herein. Utility Model Content

[0005] The utility model provides a sealing structure for high-voltage busbar penetration, so as to solve the problem that people cannot quickly replace the rubber strip.

[0006] The utility model is implemented by the following technical scheme: a sealing structure for high-voltage busbar penetration, comprising a first sealing ring and a second sealing ring, wherein the outer surface of the first sealing ring is provided with a symmetrical connecting mechanism, wherein the connecting mechanism comprises a fixed pad 1 and a fixed pad 2, wherein the inner wall of the fixed pad 1 is sleeved with a connecting rod, and the top end of the connecting rod is fixedly connected with a handle pad;

[0007] The bottom surface of the handle pad is fixedly connected with a spring, the bottom surface of the fixed pad 2 is fixedly connected with a limiting gasket, the bottom end of the connecting rod is fixedly connected with a limiting plate, the limiting plate is adapted to the limiting gasket, and the limiting plate can pass through the through hole opened on the limiting gasket.

[0008] Furthermore, the first fixing pad is fixedly connected to the outer surface of the first sealing ring, and the second fixing pad is fixedly connected to the outer surface of the second sealing ring. The first sealing ring can support the first fixing pad, and the second sealing ring is used to support the second fixing pad.

[0009] Specifically, the spring is sleeved on the outer surface of the connecting rod, and the spring is fixedly connected to the upper surface of the first fixing pad. The spring plays a role in resetting the handle pad.

[0010] Preferably, a set of threaded holes are provided on the outer surfaces of the first sealing ring and the second sealing ring. The threaded holes are arranged in a circumferential array. Workers can use screws to install and fix the device through the first sealing ring.

[0011] Furthermore, fire-resistant rubber rings are fixedly connected to the inner walls of the first sealing ring and the second sealing ring, and a set of reinforcing plates are fixedly connected to the outer surfaces of the first sealing ring and the second sealing ring. The fire-resistant rubber ring is made of rubber with good fire resistance.

[0012] The present utility model provides a sealing structure for high-voltage busbar penetration, and its beneficial effects are as follows:

[0013] 1. Through the cooperative setting among the first sealing ring, the second sealing ring and the connecting mechanism, the sealing structure for high-voltage busbar penetration can fix the first sealing ring and the second sealing ring without relying on screws, thus meeting the rapid replacement requirement of the fire-resistant rubber ring, and at the same time avoiding the situation that it is difficult for people to disassemble the screws due to rust.

[0014] 2. Through the cooperative setting among the handle pad, the connecting rod, the limiting plate, the limiting gasket and the second fixing pad, by pressing the handle pad, at this time the limiting plate can move downward synchronously with the connecting rod, and then rotate the handle pad to drive the connecting rod and the limiting plate to rotate synchronously until the limiting plate corresponds to the limiting gasket. At this time, release the handle pad, and under the elastic force of the spring, the limiting plate can slide out of the second fixing pad to release the limitation on the first fixing pad and the second fixing pad, so as to open the first sealing ring and the second sealing ring relatively quickly to meet the rapid replacement of the fire-resistant rubber ring.
