Description

Technical Field

[0001] The utility model relates to the technical field of lightning arresters, in particular to an electrical performance test tool for lightning arresters. Background Art

[0002] The main function of the lightning arrester is to protect electrical equipment from the hazards of high transient overvoltage and limit the follow-on current time and follow-on current amplitude. It can also be used to protect against atmospheric overvoltage and operating overvoltage, ensure that the insulation of the equipment is not damaged, and clip the invading flow wave to reduce the overvoltage value of the protected equipment.

[0003] When testing some existing lightning arresters, the arrester is usually energized directly, and the quality of the lightning arrester is judged by the data displayed when the arrester is energized. However, not all lightning arresters work indoors, and some lightning arresters work in an outdoor environment. When working outdoors, the arrester will inevitably encounter rainy days, and some existing lightning arrester electrical performance test fixtures cannot simulate a rainy environment, and rainy days may make the lightning arrester damp. Therefore, the test results may deviate from the actual results in the rainy environment, which is inconvenient to use. In order to solve this technical problem, the utility model proposes an arrester electrical performance test fixture. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the utility model, through the cooperation between the cover plate and the water spray plate and other components, first the cover plate can be moved. After the lightning arrester body is placed in the device body, the cover plate can be moved to cover the upper end of the lightning arrester body, so that the power port can contact the upper end of the lightning arrester body at different heights, so that the device can perform power-on detection on lightning arresters at different heights. The water spray plate can spray water, and the liquid sprayed by the water spray can be used to spray the lightning arrester body, so as to simulate the spraying of the lightning arrester body, so that the lightning arrester body can be tested in a rainy day state, which is very convenient and solves the problem of deviation between rainy day and actual detection results.

[0015] In the utility model, through the cooperation between the inclined plate and the baffle shell and other components, first, the surface of the inclined plate has an inclined surface. When the water spray plate sprays liquid, the liquid will fall on the inclined surface of the inclined plate, and the water will be discharged into the device body through the inclined surface, so that the water can flow into the water outlet pipe, avoiding water accumulation at the threaded rod. The baffle shell can prevent water from spraying out of the device body, and the liquid sprayed from the water spray plate is blocked by the baffle shell, so that the sprayed liquid can be blocked by the baffle shell, thereby preventing the liquid from flowing out, thereby avoiding waste of water resources, and is very useful.

A groove is opened inside the device body 1, and the transmission plate 2 can move along the inner side wall of the groove of the device body 1, so as to limit the position to which the transmission plate 2 can move and prevent the transmission plate 2 from rotating. The transmission plate 2 will fix the position of the cover plate 3 and will move with the cover plate 3 when the transmission plate 2 moves.

[0024] The cover plate 3 is provided with a power port 4 installed inside, and the cover plate 3 is slidably connected to the arrester body 5 inside. The cover plate 3 will limit the position of the power port 4, and will move with the power port 4 when the cover plate 3 moves. The power line of the power port 4 will pass through the transmission plate 2, and will cover the arrester body 5 when the cover plate 3 moves up and down.

[0025] A power mechanism 6 is provided inside the device body 1, a limiting hole 7 is opened inside the device body 1, and a support seat 8 is installed inside the device body 1. The inner wall of the limiting hole 7 is relatively smooth. The power cord of the power port 4 can be connected to the outside through the limiting hole 7. The device body 1 will limit the position of the support seat 8, and the support seat 8 will be grounded.

[0026] The interior of the device body 1 is connected to a water outlet pipe 9, and the outer surface of the device body 1 is connected to a water tank 10. The water outlet pipe 9 is connected to the inner side wall of the bottom surface of the device body 1. The device body 1 will limit the position of the water outlet pipe 9 so that the internal liquid of the device body 1 can be discharged through the water outlet pipe 9. The device body 1 fixes the position of the water tank 10 so that the water tank 10 cannot move.

[0027] The interior of the water tank 10 is connected to a water suction pipe 11, the interior of the device body 1 is installed with a water spray plate 12, and the interior of the device body 1 is connected with an inclined plate 13. The water tank 10 will limit the position of the water suction pipe 11, and a water pump is installed at one end of the water suction pipe 11 in the water tank 10. The water in the water tank 10 is pumped out by the water pump. The device body 1 will limit the position of the water spray plate 12, and the device body 1 will fix the position of the inclined plate 13, and the water sprayed from the water spray plate 12 is sent into the device body 1 through the inclined surface of the inclined plate 13.

[0028] The power mechanism 6 includes a motor 601, which is installed inside the device body 1. The output end of the motor 601 is connected to a threaded rod 602. The device body 1 will fix the position of the motor 601 so that the motor 601 will not rotate when it starts. The motor 601 will fix the position of the threaded rod 602 and will rotate with the threaded rod 602 when the motor 601 starts.

[0029] The outer surface of the threaded rod 602 is connected to the internal rotation of the device body 1, the outer surface of the threaded rod 602 is connected to the internal rotation of the inclined plate 13, and the outer surface of the threaded rod 602 is connected to the internal thread of the transmission plate 2. The device body 1 and the inclined plate 13 will limit the position of the threaded rod 602 so that the threaded rod 602 will not generate large vibrations when rotating. The movement of the transmission plate 2 is controlled by the rotation of the threaded rod 602, so that the transmission plate 2 can be moved to a suitable position.

[0030] The upper surface of the transmission plate 2 is connected to a waterproof plate 14, and the outer surface of the waterproof plate 14 is slidably connected to the inside of the device body 1.

The device body 1 will fix the position of the baffle shell 15, so that the baffle shell 15 cannot be easily moved. The baffle shell 15 will block the limiting hole 7, so that the liquid will not splash out from the limiting hole 7. The power cord of the power port 4 can pass through the mounting hole 16. The power cord is almost the same size as the mounting hole 16, so that the power cord can move in the mounting hole 16, and the liquid is difficult to flow out.

[0032] The upper surface of the arrester body 5 is in contact with the power port 4, and the bottom surface of the arrester body 5 is in contact with the upper surface of the support seat 8. The arrester body 5 is energized through the contact between the power port 4 and the arrester body 5. When the arrester body 5 needs to be grounded, it contacts the support seat 8. If not, some objects can be placed between the arrester body 5 and the support seat 8. The arrester body 5 will block the support seat 8, making it difficult for rainwater to drip onto the support seat 8.

[0033] The water outlet pipe 9 is connected to the inside of the water tank 10, and the end of the water suction pipe 11 away from the water tank 10 is connected to the inside of the water spray plate 12. The outer surface of the water suction pipe 11 is connected to the inside of the device body 1.
