[0002] The power meter box is a kind of metering equipment, which is used for electric energy metering in 3~35kv, including combined transformer (collecting three-phase current and voltage signals), box, electric meter, lightning arrester, vacuum circuit breaker (prepaid type), etc. The current accuracy is 0.2S, and the voltage accuracy level is 0.2. The model is generally JLSxx-xx (x replaces the actual letter) and is basically the same as the combined transformer.

[0003] Existing metering equipment is generally installed on the outside of a lightning rod, but the lightning rod may be damaged and rusted during long-term use, and cannot effectively play a lightning protection role. The replacement of the lightning rod also requires the unscrewing of a large number of bolts for disassembly, and the replacement and installation are very troublesome. Insulating paint is generally applied to the outside of the metering equipment. During long-term use, the insulating paint will gradually become thinner and cannot achieve the insulating effect. Manual application is very troublesome and is not conducive to people's work. The insulating pad installed inside will gradually age during long-term use, and replacement is also very troublesome and cannot achieve a good fixing effect. At the same time, the metering equipment itself is relatively fragile and cannot effectively improve the protection strength. Summary of the invention

By setting the positioning mechanism 7, the rotating hand wheel 71 The rotating shaft 72 can be driven to rotate, and the rotating shaft 72 drives the third threaded column 73 to rotate, so that the third threaded column 73 drives the third threaded nut to move, and the third threaded nut drives the clamping plate 78 to move through the support rod 77, so that the clamping plate 78 can squeeze the insulating pad 79 to achieve a tight fixation. At the same time, the clamping plates 78 on both sides respectively support the left and right sides of the inside of the metering cabinet 1, thereby achieving a good reinforcement effect and increasing the overall strength of the metering cabinet 1. By setting a circular plate 75 and a bolt 76, the circular plate 75 can be fixed to the inside of the metering cabinet 1 by tightening the bolt 76. Disassembly and installation are very convenient. When the aging insulating pad 79 needs to be replaced, the hand wheel 71 is rotated to control the clamping plates 78 on both sides to no longer clamp the insulating pad 79, and then the workers can quickly replace the insulating pad 79.
