[0002] High and low voltage switchgear is an important power distribution equipment in the power system, which is used to control and protect power lines. The existing high and low voltage switchgear has a simple structure, mainly composed of switches and cabinets. When the power consumption reaches a high load, the electrical appliances inside the switchgear generate a lot of heat due to their resistance. At this time, when the heat dissipation performance of the switchgear cannot keep up with the heat generated, it will cause the electrical appliances inside the switchgear to catch fire at high temperature, causing regional power outages and causing safety risks. In addition, when the switchgear is in a severe cold environment, the moisture in the air will condense on the surface and inner wall of the switchgear, causing short circuits and insulation failure of electrical components, resulting in the inability of the equipment to operate normally; in addition, since the existing high and low voltage switchgear is a device connected to high voltage or low voltage cables, there are many electrical equipment and cables in the high and low voltage switchgear.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention sets a liquid control mechanism, evaporative liquid and cooling liquid, so that when the working load of the electrical appliances such as the hot connection mechanism, the zero connection mechanism and the connecting block in the inner cavity of the isolation frame increases continuously and the temperature increases continuously, the evaporative liquid evaporates and expands, and the volume increases continuously, so that the liquid level of the cooling liquid flowing into the cavity formed by the front of the mounting plate, the inner curved surface of the isolation frame and the rear of the middle plate increases continuously, so that the multiple floating blocks float up in sequence from right to left, and then the hot connection mechanism and the zero connection mechanism are disconnected in sequence from right to left according to the circuit from the least critical to the most critical, so as to reduce the temperature of the inner cavity of the isolation frame. In addition, when the temperature of the inner cavity of the isolation frame When the temperature decreases from high, the coolant height in the cavity formed by the front of the installation plate, the inner curved surface of the isolation frame and the back of the middle plate continues to decrease, causing multiple floating blocks to drop in sequence from left to right, thereby causing multiple hot-connection mechanisms and zero-connection mechanisms to recover in sequence from high criticality to low criticality. When the temperature inside the switch cabinet exceeds its heat dissipation capacity, circuits with low criticality are automatically disconnected first to ensure stable operation of critical circuits. At the same time, when the temperature recovers, critical circuits are automatically restored first. During peak power usage, the temperature inside the switch cabinet does not exceed its heat dissipation capacity, avoiding fire in the switch cabinet and overall power outages.

[0015] 2. In the present invention, when the temperature of the external environment causes the temperature of the switch cabinet to be too low, the evaporating gas inside the sealed cavity between the bottom surface of the upper plate, the outer side surface of the isolation frame, the inner side surface of the side plate and the upper surface of the piston shrinks and the air pressure decreases. At this time, the first elastic member pulls the insulation plate to move in the direction of the telescopic sleeve through the telescopic rod, and the insulation plate pushes the multiple connecting lines to merge toward the side plate, thereby reducing the loss of temperature of the switch cabinet. When the evaporating gas inside the sealed cavity between the bottom surface of the upper plate, the outer side surface of the isolation frame, the inner side surface of the side plate and the upper surface of the piston shrinks, the air pressure is reduced to atmospheric pressure, pushing the piston to move upward to contact with the upper support shell, the piston drives the first electric ring to contact the second electric ring, so that the heating rod is energized, and the heating rod heats the coolant to increase the temperature of the inner cavity of the isolation frame, thereby preventing moisture in the air from condensing on the inner wall of the switch cabinet and causing a short circuit.

[0016] 3. The present invention sets a monitoring device, starts the first motor in a positive direction, and the output shaft of the first motor drives the first threaded rod to rotate forward, the first threaded rod drives the sliding block to move to the left, the sliding block drives the second motor to move to the left, and then starts the second motor in a positive direction, the output end of the second motor drives the second threaded rod to rotate forward, the second threaded rod drives the camera to move upward, so that the camera moves to any position behind the cabinet door, realizes overall monitoring of the electrical components inside the isolation frame, realizes a comprehensive view of the connection status of each electrical equipment and each cable connector, and achieves a better monitoring effect.

[0026] Working principle: When the present invention is used, the electrical appliances such as the hot contact mechanism 9, the zero contact mechanism 10, and the connection block 1201, which are energized in the inner cavity of the isolation frame 7, increase in temperature under the influence of their resistance, and the isolation frame 7 transfers the generated heat to the outer side surface of the isolation frame 7, so that the evaporative liquid in the sealed cavity between the bottom surface of the upper upper plate 2, the outer side surface of the isolation frame 7, the inner side surface of the side plate 3, and the upper surface of the piston 804 evaporates and expands, and the volume increases greatly, pushing the piston 804 to move downward, and the piston 804 squeezes the second elastic member 803 to shrink downward, and the downwardly moving piston 804 pushes the upper surface of the bottom upper plate 2, the outer side surface of the isolation frame 7, the inner side surface of the side plate 3, and the piston 804 The coolant in the sealed cavity between the lower surfaces flows into the cavity formed by the front of the mounting plate 1, the inner curved surface of the isolation frame 7 and the back of the middle plate 16 through the bottom hole 701 opened at the bottom of the isolation frame 7, so that the coolant level in the cavity formed by the front of the mounting plate 1, the inner curved surface of the isolation frame 7 and the back of the middle plate 16 rises, and the coolant pushes the floating block 14 in contact with it to float up, and the floating block 14 pushes the connecting column 13 to move upward, and the connecting column 13 pushes the connecting block 1201 to move upward, and the connecting block 1201 is separated from the zero-connection mechanism 10 in sliding contact with it, so that the hot connection mechanism 9 and the zero-connection mechanism 10 connected up and down through the connecting block 1201 are de-energized; Since the heights of the plurality of floating blocks 14 are increased equidistantly from right to left and the hot connection mechanism 9 and the zero connection mechanism 10 are connected in sequence from right to left according to the circuit from the least critical to the most critical, when the working load of the electrical appliances such as the hot connection mechanism 9, the zero connection mechanism 10, the connection block 1201 in the inner cavity of the isolation frame 7 is continuously increased and the temperature is continuously increased, the evaporation expansion volume of the evaporating liquid in the sealed cavity between the bottom surface of the upper upper plate 2, the outer side surface of the isolation frame 7, the inner side surface of the side plate 3 and the upper surface of the piston 804 is continuously increased, and the liquid level of the cooling liquid in the cavity formed by the front of the mounting plate 1, the inner curved surface of the isolation frame 7 and the back of the middle plate 16 is continuously increased, so that the plurality of floating blocks 14 float up in sequence from right to left, so that the hot connection mechanism 9 and the zero connection mechanism 10 are disconnected in sequence from right to left according to the circuit from the least critical to the most critical, thereby reducing the temperature of the inner cavity of the isolation frame 7; In addition, when the temperature of the inner cavity of the isolation frame 7 decreases from high, the evaporation expansion volume of the evaporation liquid in the sealed cavity between the bottom surface of the upper plate 2, the outer side surface of the isolation frame 7, the inner side surface of the side plate 3 and the upper surface of the piston 804 continues to decrease, and the cooling liquid in the cavity formed by the front of the mounting plate 1, the inner curved surface of the isolation frame 7 and the back of the middle plate 16 flows back to the upper surface of the bottom upper plate 2, the outer side surface of the isolation frame 7, the inner side surface of the side plate 3 and the lower surface of the piston 804. The height of the cooling liquid in the cavity formed by the front of the mounting plate 1, the inner curved surface of the isolation frame 7 and the back of the middle plate 16 continues to decrease, so that the multiple floating blocks 14 descend from left to right in turn, so that the multiple fire connection mechanisms 9 and the zero connection mechanisms 10 are restored in turn from the high criticality to the low criticality, so that when the temperature inside the switch cabinet exceeds its heat dissipation capacity, the circuit with low criticality is automatically disconnected first to ensure the stable operation of the critical circuit. At the same time, when the temperature is restored, the critical circuit is automatically restored first. During the peak period of power use, the temperature inside the switch cabinet does not exceed its heat dissipation capacity, thereby avoiding fire and overall power failure of the switch cabinet; In addition, when the present invention is used, when the temperature of the inner cavity of the isolation frame 7 increases, the gas evaporated and expanded by the evaporative liquid in the sealed cavity between the bottom surface of the upper plate 2, the outer side surface of the isolation frame 7, the inner side surface of the side plate 3 and the upper surface of the piston 804 flows into the inner cavity of the telescopic sleeve 601, and the expanded gas in the inner cavity of the telescopic sleeve 601 pushes the telescopic rod 603 to extend to the side away from the telescopic sleeve 601. At the same time, the telescopic rod 603 pulls the first elastic member 602 to extend, and the telescopic rod 603 drives the sleeve frame 607 to move to the side away from the telescopic sleeve 601. The insulation plate 604 drives the multiple connecting wires 608 to separate from each other through the connecting wire 608. At this time, the heat in the inner cavity of the isolation frame 7 is transferred to the surface of the connecting wire 608 through the isolation frame 7, the coolant, the side plate 3 and the heat-conducting column 605, and the connecting wire 608 transfers the heat to the air, thereby realizing the heat dissipation of the electrical appliances such as the hot connection mechanism 9, the zero connection mechanism 10, and the connecting block 1201 in the inner cavity of the isolation frame 7. When the temperature of the environment causes the temperature of the switch cabinet to be too low, the contraction pressure of the evaporating gas inside the sealed cavity between the bottom surface of the upper plate 2, the outer side surface of the isolation frame 7, the inner side surface of the side plate 3 and the upper surface of the piston 804 decreases. At this time, the first elastic member 602 pulls the insulation plate 604 to move in the direction of the telescopic sleeve 601 through the telescopic rod 603, and the insulation plate 604 pushes the multiple connecting wires 608 to merge in the direction of the side plate 3, thereby reducing the loss of the temperature of the switch cabinet. When the contraction pressure of the evaporating gas inside the sealed cavity between the bottom surface of the upper plate 2, the outer side surface of the isolation frame 7, the inner side surface of the side plate 3 and the upper surface of the piston 804 decreases to the atmospheric pressure, pushing the piston 804 to move upward to contact the upper support shell 801, the piston 804 drives the first electric ring 805 to contact the second electric ring 806, and the heating rod 802 is energized. The heating rod 802 heats the coolant to increase the temperature of the inner cavity of the isolation frame 7, thereby preventing water droplets from adhering to the switch cabinet and causing a short circuit. In addition, when the present invention is used, when the controller 1706 controls the electromagnetic switch 1705 on the far right to be disconnected, the electromagnetic ring 1702 on the far right is powered off, and the fourth elastic member 1704 pushes the joint mechanism 12 to move upward, so that the connection block 1201 is separated from the zero connection mechanism 10 with which it is slidably sleeved, thereby disconnecting the hot connection mechanism 9 and the zero connection mechanism 10 on the far right. Similarly, multiple groups of hot connection mechanisms 9 and zero connection mechanisms 10 are controlled, and the switch cabinet circuit is controlled remotely by humans. In addition, when the present invention is used, the first motor 1801 is started in the forward direction, and the output shaft of the first motor 1801 drives the first threaded rod 1802 to rotate forward, and the first threaded rod 1802 drives the sliding block 1803 to move to the left, and the sliding block 1803 drives the second motor 1804 to move to the left, and then the second motor 1804 is started in the forward direction, and the output end of the second motor 1804 drives the second threaded rod 1805 to rotate forward, and the second threaded rod 1805 drives the camera 1806 to move upward, so that the camera 1806 moves to any position behind the cabinet door 5, so as to realize the overall monitoring of the electrical components inside the isolation frame 7.
