Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a surge arrester that can be replaced while energized. Background Technology

[0002] A surge arrester is connected between the cable and the ground, usually in parallel with the protected equipment. Surge arresters effectively protect communication equipment; they activate in the event of abnormal voltage to provide protection. When the communication cable or equipment is operating under normal operating voltage, the surge arrester does not function and is considered an open circuit to the ground. However, if a high voltage occurs that threatens the insulation of the protected equipment, the surge arrester immediately activates, diverting the high-voltage surge current to the ground, thereby limiting the voltage amplitude and protecting the insulation of the communication cable and equipment. Once the overvoltage dissipates, the surge arrester quickly returns to its original state, allowing the communication line to operate normally.

[0003] However, the maintenance and replacement of existing surge arresters usually require power outages, which seriously affects normal power supply, is time-consuming, and has low work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a surge arrester that can be replaced while energized, in order to solve the technical problem of how to replace surge arresters while energized.

[0005] This utility model is achieved by the following technical solution: a surge arrester that can be replaced while energized, comprising a surge arrester body and a connector. The surge arrester body is provided with a protrusion on its top, and the connector is provided with a double helical snap-fit ​​structure. The surge arrester body is connected to the double helical snap-fit ​​structure on the connector through the protrusion to achieve fastening. The connector is connected to an insulator.

[0006] Furthermore, it also includes a detachable mounter, which is disposed at the lower end of the surge arrester body.

[0007] Furthermore, the lower end of the surge arrester body is provided with an opening, and a ball groove is provided inside the opening. A ball is provided on the detachable installer, and the ball is connected to the ball groove.

[0008] Furthermore, the detachable mount is also provided with a ball control button for adjusting the insertion or removal of the ball from the ball groove. The ball control button is connected to the ball. When the ball is inserted into the ball groove, the surge arrester body is fastened to the detachable mount; when the ball is removed from the ball groove, the surge arrester body is separated from the detachable mount.

[0009] Furthermore, the connector is also provided with a guide port, through which the surge arrester body is inserted into the connector.

[0010] Furthermore, the connector is also provided with a guide post, and a reinforcing rib is provided inside the guide post. The reinforcing rib is connected to a spring inside the surge arrester body.

[0011] Furthermore, the surge arrester body is also equipped with a spring positioning pin.

[0012] Furthermore, the connector is also provided with a sensing conductor, which is connected to the indicator light.

[0013] The beneficial effects of this utility model are as follows: This utility model can realize the function of long-distance replacement of the surge arrester body by means of the cooperation between the protrusion on the top of the surge arrester body, the double helix buckle structure of the connector, and the detachable installer.

[0019] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0020] See Figure 1 A surge arrester that can be replaced while energized is characterized in that it includes a surge arrester body 1 and a connector 2. The surge arrester body 1 is provided with a protrusion 8 on its top. The connector 2 is provided with a double helical snap-fit ​​structure 6. The surge arrester body 1 is connected to the double helical snap-fit ​​structure 6 on the connector 2 through the protrusion 8 to achieve fastening. The connector 2 is connected to an insulator (not shown in the figure). It also includes a detachable installer 14, which is provided at the lower end of the surge arrester body 1.

[0021] In this embodiment, the lower end of the surge arrester body 1 is provided with an opening 11, and a ball bearing groove 12 is provided inside the opening 11. A ball bearing 13 is provided on the detachable mount 14, and the ball bearing 13 is connected to the ball bearing groove 12. Furthermore, the detachable mount 14 is also provided with a ball bearing control button 15 for adjusting the insertion or removal of the ball bearing 13 from the ball bearing groove 12, and the ball bearing control button 15 is connected to the ball bearing 13. When the ball bearing 13 is inserted into the ball bearing groove 12, the surge arrester body 1 is secured to the detachable mount 14. At this time, the surge arrester body 1 can be installed by rotating the detachable mount 14. When the ball bearing 13 is removed from the ball bearing groove 12 by using the ball bearing control button 15, the surge arrester body 1 can be separated from the detachable mount 14.
