Description

Technical Field

[0001] This utility model relates to the field of side expansion bus coupler technology, and in particular to a side expansion bus coupler with an embedded temperature sensor. Background Technology

[0002] In power systems, side-expanded gas-insulated switchgear requires bus couplers to transmit electrical energy. However, under high current and high load operation, the bus coupler and its surrounding components may experience excessively high local temperatures due to overload, poor contact, or other reasons, leading to malfunctions or even serious consequences such as fires or explosions.

[0003] Currently, traditional bus couplers typically lack temperature acquisition and monitoring capabilities, or rely on external temperature monitoring on the insulating outer surface of the coupler's casing. This not only increases installation complexity but also fails to provide a direct and accurate reflection of the actual temperature at the busbar contact points. Therefore, this invention proposes a side-expansion bus coupler with an embedded temperature sensor to address the shortcomings of existing technologies. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a side-expansion bus coupler with an embedded temperature sensor. By directly embedding the temperature sensor into a metal conductive component inside the insulating shell, the temperature sensor is located inside the bus coupler, reducing interference from external environmental factors, improving the accuracy of temperature monitoring, and enabling the monitoring and early warning of potential thermal faults using the temperature sensor, thereby reducing the risk of safety accidents caused by overheating.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A side-expansion bus coupler with an embedded temperature sensor includes an insulating shell, a metal conductive component, and a temperature sensor. The insulating shell is inserted into two symmetrically arranged sets of side-expansion sleeves at both ends. The insulating shell contains a metal conductive component, which includes an aluminum support block, a first elastic clamp, a second elastic clamp, and conductive sheets. At least three sets of conductive sheets are arranged in a ring array outside the aluminum support block. A first elastic clamp is located on the outer side of one end of each set of conductive sheets, and a second elastic clamp is located on the outer side of the other end of each set of conductive sheets. One end of the first elastic clamp is flush with one end of each set of conductive sheets, and one end of the second elastic clamp is flush with the other end of each set of conductive sheets. The aluminum support block has a mounting groove, and the temperature sensor is disposed within the mounting groove.

[0007] A further improvement is that the insulating outer shell includes an intermediate shell and end shells, with end shells at both ends of the intermediate shell. The intermediate shell is a hollow cylindrical structure, and the end shells are hollow frustum structures.

[0008] A further improvement is that: the outer wall of the intermediate shell is provided with reinforcing ribs, and two sets of reinforcing ribs are symmetrically arranged.

[0009] A further improvement is that the first elastic clamp has a first notch, and the second elastic clamp has a second notch.

[0010] A further improvement is that the conductive sheet includes a middle arc segment and two end arc segments, and the middle arc segment and the two end arc segments are integrally formed.

[0011] A further improvement is that the arc length of the end arc segment is less than the arc length of the middle arc segment, and the heights of the first elastic clamp and the second elastic clamp are adapted to the length of the end arc segment.

[0012] The beneficial effects of this utility model are as follows: By directly embedding the temperature sensor into the metal conductive component inside the insulating shell, the temperature sensor is located inside the bus coupler, which reduces the interference of external environmental factors, improves the accuracy of temperature monitoring, and enables the use of the temperature sensor to monitor and warn of potential thermal faults, thereby reducing the risk of safety accidents caused by overheating.

[0013] The side expansion bus coupler structure of this utility model with embedded temperature sensor has a high degree of integration, which can simplify the on-site installation steps and improve the service life of power equipment. Attached Figure Description

[0021] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0022] according to Figure 1-6 As shown, this embodiment proposes a side-expansion bus coupler with an embedded temperature sensor, including an insulating shell 1, a metal conductive component 2, and a temperature sensor 3. The insulating shell 1 is inserted into two sets of symmetrically arranged side-expansion sleeves 4 at both ends. The insulating shell 1 contains the metal conductive component 2, which includes an aluminum support block 201, a first elastic clamp 202, a second elastic clamp 203, and a conductive sheet 204. The conductive sheet 204 is a copper plate, and at least three sets of conductive sheets 204 are provided. Multiple sets of conductive sheets 204 are arranged in a ring array on the outside of the aluminum support block 201. A first elastic clamp 202 is provided on the outer side of one end of each set of conductive sheets 204, and a second elastic clamp 203 is provided on the outer side of the other end. One end of the first elastic clamp 202 is flush with one end of each set of conductive sheets 204, and one end of the second elastic clamp 203 is flush with the other end of each set of conductive sheets 204. The aluminum support block 201 has a mounting groove 5, and a temperature sensor 3 is installed within the mounting groove 5. The temperature sensor 3 of this invention is connected to the monitoring system wirelessly for data exchange. The temperature sensor 3 transmits the collected temperature data to the monitoring center in real time for data analysis and early warning.

[0023] The insulating outer shell 1 includes an intermediate shell 101 and end shells 102. The intermediate shell 101 has end shells 102 at both ends. The intermediate shell 101 is a hollow cylindrical structure, and the end shells 102 are hollow frustum structures. Reinforcing ribs 103 are provided on the outer wall of the intermediate shell 101, with two sets of reinforcing ribs 103 symmetrically arranged. This arrangement improves the ease of installation of the metal conductive component 2 inside the insulating outer shell 1. The reinforcing ribs 103 also enhance the overall structural strength of the insulating outer shell 1.

[0024] The first elastic clamp 202 is provided with a first notch 6, and the second elastic clamp 203 is provided with a second notch 7. By providing the first notch 6 and the second notch 7, the convenience of fixing multiple sets of conductive sheets 204 by the first elastic clamp 202 and the second elastic clamp 203 can be improved, and the first elastic clamp 202 and the second elastic clamp 203 can have good deformation capacity.

[0025] The conductive sheet 204 includes a middle arc segment 8 and two end arc segments 9. Both ends of the middle arc segment 8 are provided with end arc segments 9, and the middle arc segment 8 and the two end arc segments 9 are integrally formed. The arc length of the end arc segment 9 is less than the arc length of the middle arc segment 8, and the heights of the first elastic clamp 202 and the second elastic clamp 203 are adapted to the length of the end arc segment 9.

[0026] This invention embeds the temperature sensor 3 directly into the metal conductive component 2 inside the insulating shell 1, placing the temperature sensor 3 inside the bus coupler. This reduces interference from external environmental factors, improves the accuracy of temperature monitoring, and enables the monitoring and early warning of potential thermal faults using the temperature sensor 3, reducing the risk of safety accidents caused by overheating. The side-expanded bus coupler structure with embedded temperature sensor of this invention has a high degree of integration, which simplifies on-site installation steps and extends the service life of power equipment.
