Description

Technical Field

[0001] The utility model relates to the technical field of arrester performance detection, in particular to a performance detection device for high-voltage arresters. Background Technique

[0002] High-voltage arresters can actually be seen on buildings in our daily life. The main function of high-voltage lightning rods is to protect buildings, electrical equipment and the human body from lightning or electric shock. Under normal working voltage, a high-voltage arrester is equivalent to an insulator, and the current passing through its interior is only in the microampere level. Under overvoltage conditions during operation, the resistance value of the high-voltage arrester will decrease sharply, and the current passing through the interior will increase thousands of times instantaneously. That is to say, at this time, the high-voltage arrester is in a conducting state, and releasing a certain voltage can effectively control the infringement of the voltage on power transmission and transformation equipment. Before the high-voltage arrester leaves the factory, in order to ensure the quality of the high-voltage arrester, it is necessary to perform performance detection operations on the high-voltage arrester. When performing the detection, an arrester detector needs to be used and connected to the high-voltage arrester through a wire to detect the AC leakage current of the high-voltage arrester under operating voltage.

[0003] When detecting a high-voltage arrester, in order to ensure the normal progress of the detection process, it is necessary to fix the high-voltage arrester, and then test the high-voltage arrester. When the test work of the high-voltage arrester is completed, it is necessary to release the fixation of the high-voltage arrester and remove the arrester, and then re-fix the high-voltage arrester to be detected and connect the wire to the high-voltage arrester to be detected to continue the test operation. Time is wasted on fixing and removing the arrester, and this method makes the time required for the whole test longer and the efficiency lower.

The top end of the connecting rod 808 is fixedly connected with a pressing plate 809. The pressing plate 809 is made of insulating material. A second positioning jack 810 is provided on one side of the pressing plate 809.

[0032] 4) The starter 5 causes the turntable 6 to drive the arrester to rotate, rotating the untested arrester to the detection station for detection operation.

At this time, the connecting rod 808 will move upward and stretch the fixing spring 807, separating a terminal on the tested arrester from the second positioning jack 810, and separating a terminal on the tested arrester from the first positioning jack 7. At this time, the tested arrester can be removed;

[0033] 5) Repeat steps 1, 2, 3, and 4 to continue the installation, disassembly, and detection operations on the arrester.

When detecting a large number of arresters, the required time is less, improving the detection efficiency of the arrester, and being able to fix and detect arresters of more heights, expanding the applicable range of the device, and improving the practicality and structural flexibility of the device.
