[0025] A card holder 2 is engaged with the outside of the relay body 1, and the card holder 2 includes a card plate 201 and an insulating layer 202. The insulating layer 202 is wrapped around the outside of the card plate 201. A thermometer 4 is installed on one side of the card holder 2 through a mounting seat. Heat dissipation components 5 are provided on both sides of the card holder 2. The heat dissipation components 5 include a ventilation box 501 fixed on both sides of the card holder 2 by bolts. An exhaust fan 502 is installed inside the ventilation box 501 through a mounting frame. A hanging plate 7 is provided on the top of the card holder 2, and a digital current and voltage meter 3 is installed on the top of the hanging plate 7 through a mounting frame. Reinforcement components 6 are provided at both ends of the top of the card holder 2. The reinforcement component 6 includes a structural seat 601 fixed at both ends of the top of the card holder 2. A connecting rod 602 is sleeved through the inside of the structural seat 601, and a clamping block 603 is provided at one end of the connecting rod 602.

[0026] Among them, a thermal pad 503 is glued to one side of the ventilation box 501, and a dustproof net 505 is fixed to the other side of the ventilation box 501 through a slot. The thermal pad 503 can play a role in heat conduction and anti-slip, and the dustproof net 505 can prevent external dust from entering the ventilation box 501.

[0027] The thermal pad 503 is made of thermally conductive silicone rubber material, and through holes 504 are evenly spaced inside the thermal pad 503 . The through holes 504 pass through the ventilation box 501 , and the exhaust fan 502 extracts heat from the thermal pad 503 through the through holes 504 .
