[0018] Please refer to Figures 1-4 , an embodiment provided by the present utility model: A low-voltage capacitor compensation cabinet with an abnormal monitoring mechanism, including a compensation cabinet body 1 and an upper cabinet cover 2 installed at the opening position at the top of the compensation cabinet body 1, and a cabinet door monomer 5 is installed on one side of the surface of the compensation cabinet body 1 through a hinge;

[0019] L-shaped footrests 4 are integrally formed at the bottom corner positions of the upper cabinet cover 2, and the upper cabinet cover 2 is slidably sleeved with the top of the compensation cabinet body 1 through the L-shaped footrests 4. A monitoring unit 3 is installed on the top wall of the upper cabinet cover 2, and longitudinal docking beams 9 are fixed at the corner positions at the top of the upper cabinet cover 2. Support plates 6 for supporting the longitudinal docking beams 9 and bolted to the longitudinal docking beams 9 are fixed on the left and right inner walls of the compensation cabinet body 1;

[0020] Operation and maintenance personnel can directly open the upper cabinet cover 2 for necessary adjustment or maintenance without long downtime or cumbersome operation steps;

[0021] The compensation cabinet body 1 includes four concave columns 101 and a chassis 102 installed at the bottom ends of the four concave columns 101. Side baffles 103 are installed between two concave columns 101 in the same Y-axis direction, and a back plate 104 is installed between two concave columns 101 in the same X-axis direction. The longitudinal docking beam 9 is slidably engaged with the concave column 101;

[0022] The monitoring unit 3 is a smoke alarm 301 and a temperature and humidity sensor 302 installed on the top wall of the upper cabinet cover 2. The smoke alarm 301 can detect potential fire risks and issue alarms in a timely manner to prevent fire accidents, while the temperature and humidity sensor 302 monitors the temperature and humidity changes inside the cabinet in real time, so as to monitor the abnormal fluctuations of environmental parameters in real time and prevent equipment failures caused by excessive temperature or humidity inside the compensation cabinet body 1;

[0023] A through hole 901 is provided inside the longitudinal docking beam 9, and an external threaded rod 7 is installed inside the through hole 901. The bottom end of the external threaded rod 7 penetrates to the outside of the support plate 6 and a nut 8 is installed. A counterbore 201 that is concentric with the through hole 901 and extends downward is provided at the top end of the upper cabinet cover 2. The diameter of the counterbore 201 is larger than the diameter of the through hole 901. When the compensation cabinet body 1 and the upper cabinet cover 2 are connected, the longitudinal docking beam 9 on the inner wall of the upper cabinet cover 2 is slidably inserted into the corresponding concave column 101 until the bottom end of the longitudinal docking beam 9 contacts the top end of the support plate 6. At this time, the staff can take out the external threaded rod 7 so that the external threaded rod 7 passes through the counterbore 201 and the through hole 901 until the end of the longitudinal docking beam 9 penetrates through the support plate 6;

[0024] The staff takes out the nut 8 and assembles it on the threaded section of the longitudinal docking beam 9 to tighten the longitudinal docking beam 9 and the support plate 6 by using the nut 8, so that the installation between the upper cabinet cover 2, the longitudinal docking beam 9 and the support plate 6 is stable. Through a tight bolted connection, it can effectively prevent moisture, dust or other pollutants in the external environment from entering the inside of the capacitor compensation cabinet;

[0025] Columnar cavities for the external threaded rod 7 to pass through are provided on both sides inside the support plate 6. The length of the external threaded rod 7 is 50 cm to 100 cm, and the operation and maintenance personnel can easily untie or fix the external threaded rod 7 to complete the installation or disassembly operation of the upper cabinet cover 2 without using complex tools or spending too much time.

[0026] When the embodiment of the present application is in use, first, the staff pre-installs and commissions the monitoring unit 3 on the top of the upper cabinet cover 2, and then suspends or lifts the upper cabinet cover 2 to the top opening of the compensation cabinet body 1, and calibrates the upper cabinet cover 2 and the compensation cabinet body 1 through the L-shaped footrest 4. At this time, the upper cabinet cover 2 and the compensation cabinet body 1 are sleeved and docked through the L-shaped footrest 4 until the top of the compensation cabinet body 1 contacts the top wall of the upper cabinet cover 2. Subsequently, the staff uses the bolt connection structure to connect the longitudinal docking beam 9 and the support plate 6, so that the installation between the upper cabinet cover 2 and the compensation cabinet body 1 is stable, thus completing the installation of the monitoring unit 3 and the compensation cabinet body 1. In the later stage, when checking, debugging and replacing the monitoring unit 3 and other operations, the staff can release the connection between the compensation cabinet body 1 and the upper cabinet cover 2, and remove the upper cabinet cover 2 and the monitoring unit 3 as a whole from the compensation cabinet body 1 for maintenance and repair operations, so that the operation and maintenance personnel do not need to go deep into the low-voltage capacitor compensation cabinet for operation. When it is necessary to frequently read data, debug or replace the monitoring unit 3, this design significantly improves the convenience and efficiency of the staff's operation, that is, the operation and maintenance personnel can directly open the upper cabinet cover 2 for necessary operations, simplifies the maintenance process, and this structural design reduces the risks of electric shock and arc flash during the operation, improving the safety of the work.
