Description

Technical Field

[0001] The utility model relates to a side-expanding bus coupler, in particular to a side-expanding bus coupler that can be flexibly grounded. Background Technique

[0002] The side-expanding bus coupler, also known as the side-expanding busbar connector, is mainly used for the connection between ring main units. Its function is to provide multiple series connections for the expansion of ring main units and can improve the reliability of the power system. It is an optimal solution for combined ring main units.

[0003] The existing side-expanding bus coupler realizes grounding by contacting the cabinet body through the semiconductive layer. However, the margin of the semiconductive layer on the side-expanding bus coupler is limited, so there may be a situation of unreliable grounding, which affects the safe operation of the equipment. Secondly, to achieve reliable connection, the side-expanding bus coupler needs to fit well with the cabinet body structure, and the cabinet body may need to be adjusted. Some cabinet bodies even cannot adapt to the side-expanding bus coupler, resulting in a limited application range. Content of the Utility Model

[0004] In order to overcome the disadvantages that the margin of the semiconductive layer on the side-expanding bus coupler is limited, so there may be a situation of unreliable grounding, which affects the safe operation of the equipment, and some cabinet bodies even cannot adapt to the side-expanding bus coupler, resulting in a limited application range, the utility model provides a side-expanding bus coupler that can be flexibly grounded.

[0005] Technical Solution: A side-expanding bus coupler that can be flexibly grounded includes a semiconductive layer, a wire passing sleeve, a semiconductive tape, and a copper braid. The wire passing sleeves are connected to both the left and right sides of the semiconductive layer. The semiconductive tape is wound around the semiconductive layer, and the copper braid is connected to the semiconductive tape.

[0006] In a preferred embodiment of the utility model, an insulating sleeve is further included, and the insulating sleeves are connected to the outside of the wire passing sleeves.

[0007] In a preferred embodiment of the utility model, an annular airbag, an air duct, and an air inlet pipe are further included. The annular airbags are connected to the insulating sleeves. The two annular airbags are connected through the air duct. The air duct passes through the wire passing sleeve and the insulating sleeve, and the air inlet pipe is connected to the air duct.

[0008] In a preferred embodiment of the utility model, a limiting ring is further included. Two limiting rings for limiting the semiconductive tape are connected to the semiconductive layer, and the semiconductive tape is located between the two limiting rings.

[0009] In a preferred embodiment of the utility model, a connecting ring is further included, and the connecting ring is connected to the copper braid.

[0010] Compared with the prior art, the utility model has the following advantages: 1. By inserting the wire passing sleeve into the cabinet body, the cabinet bodies can be connected. Contacting the copper braid with the cabinet body can achieve flexible grounding without adjusting the cabinet body, which has a wider application range. Moreover, both ends of the copper braid are stably in contact with the semi-conductive layer and the cabinet body, ensuring the safe operation of the equipment.

[0011] 2. Air can be introduced into the annular airbag through the air duct, causing the annular airbag to collide. The annular airbag will be in close contact with the cabinet body, thereby improving the stability of the semi-conductive layer and the wire passing sleeve and preventing the semi-conductive layer and the wire passing sleeve from falling off the cabinet body.

[0017] Although the utility model may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the utility model. Those of ordinary skill in the art will recognize that terms such as "above", "below", "upward", "downward", etc. are used to describe the drawings and do not represent limitations on the scope of the utility model defined by the appended claims. Any numerical labels such as "first" or "second" are merely illustrative and are not intended to limit the scope of the utility model in any way.

[0018] As Figure 1 and Figure 2 shown, a side-expanded bus coupler with flexible grounding includes a semi-conductive layer 1, a wire passing sleeve 2, a semi-conductive tape 3 and a copper braid 4. The wire passing sleeves 2 are connected to both the left and right sides of the semi-conductive layer 1. The semi-conductive tape 3 is wound around the semi-conductive layer 1, and the copper braid 4 is connected to the semi-conductive tape 3.

[0019] As Figure 1As shown, it further includes an insulating sleeve 5, and insulating sleeves 5 are externally connected to the wire passing sleeves 2.

[0020] As Figure 1 , Figure 3 and Figure 4 As shown, it further includes an annular airbag 6, an air duct 7 and an air inlet pipe 8. Annular airbags 6 are connected to the mutually remote sides of the two insulating sleeves 5. An air duct 7 is connected between the two annular airbags 6. The air duct 7 passes through the wire passing sleeve 2 and the insulating sleeve 5. The middle of the bottom of the air duct 7 is connected to an air inlet pipe 8.

[0021] As Figure 2 As shown, it further includes a limiting ring 9. Two limiting rings 9 are externally connected to the semi-conductive layer 1, and the semi-conductive tape 3 is located between the two limiting rings 9.

[0022] As Figure 1 As shown, it further includes a connecting ring 10. The upper end of the copper braid 4 is connected to a connecting ring 10.

[0023] The staff inserts the wire passing sleeve 2 onto the cabinet body to connect between the cabinet bodies. The insulating sleeve 5 contacts the cabinet body. The insulating sleeve 5 can isolate the semi-conductive layer 1 from the external environment, avoiding current leakage or short circuit. The air inlet pipe 8 can be connected to a pump, and then the air inlet pipe 8 is opened. Air is injected into the air inlet pipe 8 through the pump. The air flows into the annular airbag 6 through the air duct 7, causing the annular airbag 6 to expand. The annular airbag 6 will be in close contact with the cabinet body, thereby improving the stability of the semi-conductive layer 1 and the wire passing sleeve 2 and preventing the semi-conductive layer 1 and the wire passing sleeve 2 from falling off the cabinet body. Then the air inlet pipe 8 is closed, and the pump is disconnected from the air inlet pipe 8. Then the staff makes the copper braid 4 contact the cabinet body to achieve flexible grounding. The cabinet body does not need to be adjusted, and the application range is wider. The two ends of the copper braid 4 are stably in contact with the semi-conductive layer 1 and the cabinet body, ensuring the safe operation of the equipment. The connecting ring 10 can be connected to the cabinet body to improve the stability of the contact between the copper braid 4 and the cabinet body. The limiting ring 9 can limit the copper braid 4 to prevent the copper braid 4 from losing contact with the semi-conductive layer 1.
