In this structure, a counter is fixedly connected to the support, and the counter is connected with the lower static contact.

In this structure, the upper static contact and the lower static contact respectively include a fixed piece on which an upper contact finger and a lower contact finger are fixed. The upper contact finger and the lower contact finger are respectively two parallel plates with open outer ends. An upper limit arc and a lower limit arc are respectively designed on the finger and the lower contact finger, and the upper limit arc corresponds to the lower limit arc.

In this structure, the lower static contact bracket includes a fixing plate, and the lower end of the fixing plate is designed with two hooks, one end of the two hooks is fixedly connected, and the other end of the two hooks is separated.

The advantages and effects of the present invention are: due to the structure of the present invention, the lightning arrester and the isolating switch are installed in combination, so the space occupied by the separate installation of the lightning arrester, the connecting wires and the use structure are reduced, and the high-voltage equipment does not need to be powered off, and the staff do not need to climb high The arrester can be tested or replaced.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

As shown in Figures 1 and 2, the present invention is a lightning arrester installation bracket, which includes a disconnector 1, and a fixing seat 16 is designed under the disconnector 1, and is characterized in that a frame 15 is fixedly connected between the fixing seat 16 and the disconnector 1, The right side of the frame 15 is fixedly connected with a bracket 14, the right end of the bracket 14 is fixedly connected with an insulator 12, the right end of the insulator 12 is fixedly connected with a lower static contact bracket 11, and the upper end of the lower static contact bracket 11 is fixedly connected with a lower static contact Head 10, the lower moving contact is placed in the lower static contact bracket 11, the lower operating rod 8 is connected to the lower static contact bracket 11, the lightning arrester 7 is connected to the lower operating rod 8, and the upper operating rod 7 is connected to the upper end of the lightning arrester 7. Rod 6, the upper end of the upper operating rod 6 is designed with an upper movable contact 4, the upper end of the disconnector 1 is fixedly connected with an upper connecting plate 2, and the right end of the upper connecting plate 2 is designed with an upper static contact 3, and the upper static contact 3 is connected to the above-mentioned The upper moving contact 4 is in contact with each other, the lower operating ring 9 is fixedly connected to the left side of the lower operating rod 8 , and the upper operating ring 5 is fixedly connected to the right side of the upper operating rod 6 . In this embodiment, a counter 13 is fixedly connected to the bracket 14 , and the counter 13 is connected to the lower static contact 10 . In this embodiment, the upper static contact 3 and the lower static contact 10 respectively include a fixed piece 21, and an upper contact finger 18 and a lower contact finger 19 are fixed on the fixed piece 21, and the upper contact finger 18 and the lower contact finger 19 are respectively Two parallel plates with open outer ends, upper contact fingers 18 and lower contact fingers 19 are respectively designed with an upper limit arc 17 and a lower limit arc 20, the upper limit arc 17 and the lower limit arc 20 correspond. In this embodiment, the lower static contact bracket 11 includes a fixing plate, and the lower end of the fixing plate is designed with two hooks, one end of the two hooks is fixedly connected, and the other end of the two hooks is separated.
