It has the advantages of high measurement accuracy, light weight, easy installation, and anti-theft of electricity. This type of electric energy meter box is suitable for outdoor three-phase system lines with rated voltage of 6, 10, 35KV and rated frequency of 50HZ.

[0033] Working principle: In actual use, the base 1 is installed in a suitable position. When installing the box body 3, first rotate the two threaded rods 25. The rotation of the threaded rods 25 will drive the threaded plate 26 connected by the thread to move upward. The upward movement of the threaded plate 26 will drive the vertical rod 27 to move upward. The movement of the vertical rod 27 will pull the pull rod 28. At this time, the two pull rods 28 move and pull the pull plate 29. The pull plate 29 can be limited by the slide groove to make the pull plate 29 move laterally stably. At this time, the two pull plates 29 move to the side away from each other and compress the positioning spring 31. The movement of the pull plate 29 will drive the limit block 30 to move. At this time, the box body 3 can be placed on the top of the base 1, so that the limit plate 24 is inserted into the fixed box 2. At this time, the threaded rod 25 is rotated to reset. The rotation of the threaded rod 25 will drive the threaded plate 26 connected by the thread to move downward, and the downward movement of the threaded plate 26 will drive the vertical rod 27 to move downward. The resetting of the vertical rod 27 will drive the pull rod 28 to reset. At this time, the positioning spring 31 loses its restriction and pushes the pull plate 29 to move horizontally and reset. The resetting of the pull plate 29 drives the limit block 30 to reset and engage with the limit groove to fix the limit plate 24, so that the support plate 23 is fixed to the box body 3. At this time, the box body 3 can be fixed to achieve the effect of installing the box body 3. By opening the box body 3, the electrical equipment can be installed on the inner wall of the box body 3. When the electrical equipment needs to dissipate heat, the fan 6 is started. After the fan 6 is running, it drives the air to move upward. At this time, negative pressure will be generated at the bottom of the box body 3, so that the air near the box body 3 will be sucked into the fixed box 2 , the impurities in the incoming air are filtered through the filter plate 9, and the air is driven upward by the fan 6 to blow the power equipment, so as to take away the heat generated by the operation of the power equipment. The left and right sides of the box 3 are provided with heat dissipation holes, and the hot air will be discharged from the heat dissipation holes. The temperature in the box 3 is detected by the temperature monitor 5. When the temperature in the box 3 reaches the set threshold, the temperature monitor 5 will transmit a signal to the alarm 4, so that the alarm 4 will alarm for warning. When it is necessary to replace or clean the filter plate 9 for filtering the air, first push the push plate 11 to move horizontally. The horizontal movement of the push plate 11 will drive the slide plate 12 to move right. At this time, the movement of the slide plate 12 will drive the sliding sleeve to move horizontally on the outer wall of the slide rail stably, and at the same time, the movement of the slide plate 12 will drive the cross bar 13 to move horizontally. When the filter plate 9 is unlocked, the filter plate 9 can be removed and the filter plate 9 can be removed. When the filter plate 9 is removed, the filter plate 9 can be removed and the filter plate 9 can be removed. When the filter plate 9 is removed, the filter plate 9 can be removed and the filter plate 9 can be removed. When the filter plate 9 is removed, the filter plate 9 can be removed and the filter plate 9 can be removed.The positioning block 21 is aligned with the buckle 22, and the push plate 11 is released. The reset spring 19 and the push spring 20 lose their restrictions and push the connecting plate 18 to reset. The reset of the connecting plate 18 will drive the positioning block 21 and the buckle 22 to engage and fix the filter plate 9, thus achieving the effect of disassembling, cleaning and replacing the filter plate 9.
