According to the regulations, preventive electrical tests need to be carried out regularly. When conducting the preventive test of the 10kV lightning arrester, limited by the on-site layout space and safety distance, the 10kV lightning arrester often needs to be removed from the fixed position and then installed on the experimental platform for testing.

[0003] Such as the 10kV lightning arrester test fixed platform with the publication number CN208043870U. After removing the 10kV lightning arrester, by adjusting the distance between the two support plates, the middle and lower umbrella skirts of the 10kV lightning arrester are inserted into the notches of the support plates, and the lower part of the 10kV lightning arrester is placed in the accommodating cavity. Sliding the two support plates closer to each other can fix the 10kV lightning arrester. The upper conductive rod of the 10kV lightning arrester is connected to the high-voltage test wire, and then by reaching into the operation hole, the lower conductive rod of the 10kV lightning arrester can be wired through the wiring hole, thus completing the fixation and test of the 10kV lightning arrester. When removing, only need to slide the support plate along the side wall to make the two support plates move away from each other, then the 10kV lightning arrester can be removed.

[0004] When testing the 10kV lightning arrester with the above scheme, it is necessary to first expand the two groups of support plates respectively, then place the 10kV lightning arrester into the accommodating cavity inside the test bench, and then move the two groups of support plates to limit the position of the 10kV lightning arrester. This way of fixing the 10kV lightning arrester is relatively cumbersome, and the position of the support plate cannot be limited, which will affect the fixing effect of the 10kV lightning arrester.

[0013] Compared with the prior art, the beneficial effects of the platform for 10kV lightning arrester test are as follows:

[0014] 1. For the platform for 10kV lightning arrester test, when fixing the lightning arrester, first rotate the threaded rod to perform threaded transmission with the threaded sleeve. The threaded sleeve will drive the two groups of connecting rods and the rotating rod to rotate and unfold, pushing the two groups of limiting plates to rotate and separate. At this time, the lightning arrester can be placed inside the fixed platform. Then, reverse-rotate the threaded rod to drive the two groups of limiting plates to approach. The lightning arrester can be fixed through the groove on one side of the limiting plate. When the test is completed, the lightning arrester can be taken out, and the two groups of limiting plates can be combined.

At this time, the baffle can be rotated and unfolded, and both sides of the fixed platform will be opened, enabling wiring of the lower conductive rod of the lightning arrester. When the experiment is completed, the two groups of limiting plates will be combined, and at this time, the blocking block will return to its initial position. To prevent foreign objects from entering the inside of the fixed platform, the two sides of the fixed platform can be blocked by rotating the baffle. When the inclined surface of the clamping block on the top of the baffle contacts the blocking block, it will move and compress the spring b. When the clamping block passes over the blocking block, the spring b will reset and push the clamping block to engage with the blocking block, completing the limit of the baffle. In this way, through the above operations, it is convenient to open and close both sides of the lightning arrester test platform. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] During specific implementation, for the platform for 10kV lightning arrester testing, when fixing the lightning arrester, first rotate the threaded rod 4 to engage in threaded transmission with the threaded sleeve 5. The threaded sleeve 5 will drive the two groups of connecting rods 6 and the rotating rod 7 to rotate and expand, pushing the two groups of limit plates 2 to rotate and separate. At this time, the lightning arrester can be placed inside the fixed platform 1. Then, reverse-rotate the threaded rod 4 to drive the two groups of limit plates 2 to approach. The lightning arrester can be fixed through the groove on one side of the limit plate 2. When the test is completed, the lightning arrester can be taken out, and the two groups of limit plates 2 can be combined. At this time, the rotation axes of the rotating block 3 and the connecting rod 6 will coincide. In order to reduce the volume of the experimental platform, by pulling the limit block 9 to squeeze the spring a 10 on one side, when the limit block 9 moves out of engagement with the fixed platform 1, the threaded rod 4 and the threaded sleeve 5 can be rotated.
