[0034] Furthermore, two transversely arranged movable support rods 115 are provided between the two inner walls of the detection heat dissipation groove 117, and the movable support rods 115 on both sides are symmetrically positioned. Three groups of heat transfer plates 114 are installed on one side wall of the detection heat dissipation groove 117. Each group of heat transfer plates 114 is composed of three heat-conducting metals. The heat transfer plates 114 and the internal components of the three-phase electric meter 112 realize heat transfer.

[0035] Furthermore, a movable detection bar 116 is provided in the detection heat dissipation slot 117 , and the detection bar 116 is slidably connected to the movable support rods 115 on both sides.

[0036] It should be further explained that a temperature meter is provided on one side of the detection bar 116 close to the heat transfer plate 114 , and the surface temperature of the heat transfer plate 114 is detected by the detection bar 116 .

[0037] It is worth further explaining that a moving device is provided inside the moving support rod 115 on one side, which can drive the detection strip 116 to move.

[0038] Furthermore, an observation panel 104 is provided above the electric meter panel 102 , and a handle groove 113 is provided in the middle of an end surface of one side of the electric meter panel 102 .

[0039] It should be further explained that the observation plate 104 is an observation glass to facilitate observation by personnel.

[0040] Furthermore, a telescopic controller 124 is installed at the lower part of the working chamber 120 near the side of the electric meter board 102. A telescopic push rod 107 that can be telescopically moved is installed in the telescopic controller 124. A contact push plate 106 is installed at the front end of the telescopic push rod 107, and the contact push plate 106 is in contact with the bottom of the end surface of one side of the electric meter board 102.

[0041] It should be further explained that when the telescopic controller 124 is started, it can drive the telescopic push rod 107 to move telescopically, and push the meter board 102 to rotate outward and open by abutting the push plate 106. At the same time, the start signal of the telescopic controller 124 is connected to the detection of the detection strip 116.

[0042] Furthermore, the two side walls inside the working chamber 120 are connected to each other and are provided with heat dissipation grooves 125 opening outward, and the heat dissipation grooves 125 on both sides are symmetrically positioned. A control support plate 110 is fixedly provided on the end faces of both sides of the meter box 101 and located outside the heat dissipation grooves 125. A rotating fan blade 110 is rotatably provided inside the heat dissipation groove 125, and the rotating fan blade 110 is rotatably connected to the control support plate 110.

[0043] It should be further explained that a power motor is provided inside the control support plate 110 , which can drive the rotating fan blades 110 to rotate, thereby achieving the effect of air flow.

[0044] It is worth further explaining that the start signal in the control support plate 110 is connected to the detection of the detection strip 116 .

[0045] Furthermore, two stabilizing suction rods 126 are provided on one side of the working chamber 120 , and the positions of the stabilizing suction rods 126 on both sides are symmetrical up and down. A telescopically movable magnetic suction rod 119 is provided inside the stabilizing suction rod 126 , and the magnetic suction rod 119 has magnetism.

[0046] Furthermore, two magnetically stable iron blocks 103 are fixedly provided on one end surface of the electric meter board 102 . The magnetically stable iron blocks 103 on both sides are symmetrical in position up and down, and the magnetically stable iron blocks 103 are magnetic.

[0047] It should be further explained that, when the electric meter panel 102 is flipped and closed, the magnetic stabilizing iron block 103 and the magnetic attraction rod 119 are magnetically attracted to each other, so that the electric meter panel 102 can be stably flipped and closed.

[0048] When using this solution, first, the meter box 101 is moved as a whole to the working position, and the circuit is set up. When a three-phase self-balancing meter is used, various parameters of the meter are detected through the three-phase meter 112, and the circuit is connected to the circuit controller 109. At this time, during normal circuit use, heat transfer is achieved through the heat transfer plate 114 and the internal components of the three-phase meter 112, and the heat is directly transferred to the detection heat dissipation slot 117, thereby improving the effect of suppressing heat generation.

[0049] At the same time, the temperature of the surface of the heat transfer plate 114 is monitored through the detection strip 116. When the temperature of the surface of the heat transfer plate 114 reaches a critical value, the detection strip 116 signal is used to control the start of the power motor in the support plate 110. At this time, the power motor is started and drives the rotating fan blades 110 to rotate, and promotes the air flow in the heat dissipation groove 125 to enter the working chamber 120, and brings the air flow into the detection heat dissipation groove 117 through the connected heat energy diffusion groove 118, and the heat transfer plate 114 is suppressed from heating.

[0050] When the temperature on the surface of the heat transfer plate 114 gradually increases and reaches the next heating critical value, the start signal of the telescopic controller 124 is connected to the signal of the detection strip 116 to start, and when the telescopic controller 124 is started, it can drive the telescopic push rod 107 to move telescopically, and push the electric meter board 102 to rotate outward and open through the abutment push plate 106. At this time, the internal space of the working chamber 120 is connected to the outside air, further improving the effect of heat suppression. At this time, when the detection strip 116 detects that the temperature of the heat transfer plate 114 is lower than the critical value, the abutment push plate 106 is reset, and the electric meter board 102 rotates and resets under the action of the rebound force of the reset spring 105, and further drives the air flow between the working chamber 120 and the electric meter board 102, and then the electric meter board 102 is closed to continue to protect the internal components of the electric meter box 101.

[0051] When the detection strip 116 detects that the temperature has increased significantly, the telescopic push rod 107 is repeatedly controlled to move telescopically. At this time, by driving the meter board 102 to rotate and reset repeatedly, the meter board 102 swings as a fan blade, promoting the flow of hot air inside the meter board 102, and realizing the heat suppression effect of the internal circuit components, further preventing the influence of excessive temperature on the operation of the three-phase self-balancing meter.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
