Description

Technical Field

[0001] The utility model relates to the technical field of arrester counters, in particular to an MOA DC arrester counter. Background Technique

[0002] The counter on the arrester is a high-voltage electrical appliance used to monitor the discharge action of the arrester. Its structure consists of a non-linear resistor, an electromagnetic counter, and some electronic components. Under normal operating voltage, the leakage current flowing through the counter is very small, and the counter does not operate. When the arrester passes through lightning waves and switching waves, a strong working current flows through the non-linear resistor of the counter, and after DC conversion, it discharges the electromagnetic coil to make the counter move once, so as to realize the device for measuring the action times of the arrester. The counter on the arrester is easily damaged. If it is not replaced in time after damage, it will affect the condition monitoring of the arrester, and there are relatively large potential safety hazards.

[0003] At present, the MOA DC arrester counter generally uses angle iron as a bracket for fixed installation, and the installation method is to install it through bolts. Although the bolt installation has good stability, it is more troublesome to disassemble in the later stage, which is not convenient for maintaining the arrester counter in the later stage, and the structure after installation is difficult to move, and the position cannot be adjusted according to the installation environment, reducing the practicability of the device. Therefore, there is an urgent need for an MOA DC arrester counter to solve the above problems. Content of the Utility Model

A docking groove 9 is provided inside the mounting frame 2, and the docking block 8 is inserted into the inside of the docking groove 9.

[0028] In this embodiment, in actual use, the number of docking grooves 9 is not less than ten, the number of mounting brackets 2 is two, and the number of docking blocks 8 on the side wall of the support plate 7 is two. When the docking block 8 cancels the clamping state with the docking groove 9, the MOA DC lightning arrester counter body 1 can be removed, improving the convenience of later maintenance. By setting a plurality of docking grooves 9 and using the docking block 8 to be clamped into the docking grooves 9 at different positions, the purpose of adjusting the installation position is achieved, improving the applicability of the device.

[0029] Specifically, referring to Figure 3 , a first gear 10 is fixedly connected to the top of the threaded rotating shaft 4, a rotating rod 11 is rotatably connected to the top of the MOA DC lightning arrester counter body 1, a second gear 12 meshing with the first gear 10 is fixedly connected to the outside of the rotating rod 11, and a rotating handle 13 is fixedly connected to the top of the rotating rod 11.
