[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1-5 As shown, the present invention provides an installation assembly for a Rogowski coil used for lightning strike detection, comprising a Rogowski coil 1 and a coil base 2 connected to the Rogowski coil 1. A connector 11 is provided at one end of the Rogowski coil 1 away from the coil base 2. A sleeve 21 for the connector 11 to be inserted is provided on the coil base 2. Installation positioning mechanisms 22 are provided on both sides of the sleeve 21.

[0024] In use, the connector 11, the socket 21 and the mounting and positioning mechanism 22 provide a quick and easy assembly for the use of Rogowski coil 1 and coil base 2 in lightning strike detection in power systems, improving the convenience of lightning strike detection in power systems.

[0025] The present invention also includes that the installation and positioning mechanism 22 includes a connecting rod 221, a positioning ball head 222 and a pressure plate 223, and the side of the connecting rod 221 near the insert 21 is rotatably connected to the insert 21 by a spring hinge 23.

[0026] The present invention further includes that the positioning ball head 222 is fixed to the end of the connecting rod 221 near the insert 21, and the pressure plate 223 is fixed to the end of the connecting rod 221 away from the positioning ball head 222.

[0027] The present invention also includes that the middle of both sides of the connector 11 is provided with positioning holes 112 corresponding to the positioning ball head 222, and the positioning ball head 222 is inserted into the corresponding positioning hole 112 through the insert sleeve 21.

[0028] In use, the installation positioning mechanism 22 enables the Rogowski coil 1 to be quickly plugged into the coil base 2, which improves the efficiency of the Rogowski coil 1 in forming a loop with the coil base 2, and makes the installation of the Rogowski coil 1 on electrical components or circuits more efficient and convenient.

[0029] The present invention also includes that guide grooves 111 are provided at both ends of the connector 11, and the ends of the guide grooves 111 are connected to the positioning holes 112.

[0030] During use, the guide groove 111 facilitates the insertion of the Rogowski coil 1 connector 11 into the sleeve 21, allowing the positioning ball head 222 to be better guided into the positioning hole 112.

[0031] In use, the Rogowski coil 1 is fitted onto the electrical equipment or line to be tested for lightning strikes. Then, the connector 11 of the Rogowski coil 1 is inserted into the sleeve 21 of the coil base 2. During the insertion, the guide groove 111 allows the positioning ball 222 to be better guided into the positioning hole 112. The spring hinge 23 provides a certain elastic extension allowance for the positioning ball 222 within the sleeve 21. After the positioning ball 222 is fully inserted into the positioning hole 112, the Rogowski coil 1 is inserted into the coil base 2, thus completing the fitting of the Rogowski coil 1 onto the electrical equipment. Then, the wires of the coil base 2 are connected to the terminal of the electrical equipment to be tested for lightning strikes, thereby providing lightning strike power data to the terminal of the electrical equipment.

[0032] When it is necessary to retract and remove the Rogowski coil 1, the pressure plates 223 on both sides of the insert 21 are pinched together. Based on the rotation of the spring hinge 23, the positioning ball head 222 at the end of the connecting rod 221 is pushed out and removed from the limit of the positioning hole 112, thereby unlocking the connector 11 of the Rogowski coil 1 and completing the removal. The operation is simple and convenient.
