[0038] The heat dissipation protection component 5 includes an internal slot 506 opened inside the workbench 1. A fan installation cover 507 is installed on the outer wall of the workbench 1. The fan installation cover 507 is communicated with the internal slot 506. A heat dissipation fan 508 is installed inside the fan installation cover 507. Two plate slots 505 are symmetrically opened at the bottom end of the installation slot 301. The plate slots 505 are located below the support plate 410 and penetrate into the interior of the internal slot 506. A vertical plate 501 is fixedly installed at the bottom end of the support plate 410. The vertical plate 501 is inserted into the plate slot 505, and the outer wall of the vertical plate 501 is in close contact with the inner wall of the plate slot 505.

Lower ventilation holes 503 are equidistantly opened at the bottom end of the side wall of the ventilation slot 502. Upper ventilation holes 504 are equidistantly opened at the side wall of the ventilation slot 502 located inside the support plate 410. A support plate 410 is arranged inside the installation slot 301. When the fixed platform 304 is installed, a gap is provided between the fixed platform 304 and the installation slot 301. At the same time, the support plate 410 moves downward, so that the lower ventilation holes 503 move into the internal slot 506. After the heat dissipation fan 508 is turned on, air can continuously flow past the outside of the fixed platform 304 to dissipate heat from the working fault monitor 305 and improve the equipment stability during the monitoring process.

[0039] Working principle: During operation, first select the required fault monitor 305 according to the faults to be monitored in the power equipment. Install the fixed platform 304 into the installation slot 301. During installation, the staff holds two handles 314. When the fixed platform 304 is lifted upward, under the action of gravity, the top plate 312 moves away from the fixed platform 304, so that the two connecting rods 313 pull the two clamping rods 309 to approach each other, and the clamping rods 309 enter the movable slot 307. After the fixed platform 304 is placed into the installation slot 301, the fixed platform 304 moves downward until it reaches the limit position. Then release the handle 314. Under the elastic force of the pressing spring 310, the two clamping rods 309 move away from each other, and the clamping rods 309 are clamped into the card slots 302 to fix the fixed platform 304. After the fixed platform 304 is fixed, the two second contacts 306 are respectively in contact with the first contacts 303 on both sides of the inner wall of the installation slot 301. During installation, install the required number of fault monitors 305 according to the number of monitored faults;

[0040] Since there are two supporting plates 410 provided on the inner side of the installation groove 301, and the supporting plates 410 are connected to the movable blocks 406 on both sides, when the fixing platform 304 is installed, the supporting plates 410 are pressed to move downward to push the movable blocks 406 to move downward. After the fixing platform 304 is fixed, the conductive rods 408 on the bottom blocks 407 at the bottom ends of the movable blocks 406 are respectively in contact with the third contact 402 and the fourth contact 403, thus facilitating power connection. At the same time, the first contact 303 on the side wall of the installation groove 301 where the fixing platform 304 is not installed cannot be powered on, avoiding accidental contact and improving the protection effect;

[0041] Subsequently, the two power connection clips 202 are connected to the power equipment, so that the fault monitor 305 is connected to the power equipment, and the power equipment is monitored through the fault monitor 305;

[0042] When the fixing platform 304 is installed inside the installation groove 301, the supporting plate 410 is pushed to move downward, so that the vertical plate 501 moves downward along the plate groove 505, and the lower ventilation holes 503 on the vertical plate 501 enter the inner groove 506. At this time, the cooling fan 508 is turned on to drive the outside air into the inner groove 506, and continuously flows through the inside of the installation groove 301 through the lower ventilation holes 503, the ventilation grooves 502 and the upper ventilation holes 504. Since the bottom of the fixing platform 304 is placed on the supporting plate 410, there is a gap between the fixing platform 304 and the inner wall of the installation groove 301, which is convenient for heat dissipation.
