DETAILED DESCRIPTION
[0018] The utility model is further described below in conjunction with the accompanying drawings.
[0019] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a power protection control cabinet for power system automation, including a control cabinet body 1, a cabinet door 2 is hinged on one side of the control cabinet body 1, a lock body 21 is arranged on the surface of the cabinet door 2, a controller 3 is arranged on the surface of the cabinet door 2, a control module 4 and a monitoring module 5 are arranged in the control cabinet body 1, the control module 4 adjusts the power supply parameters according to the change of the power load to ensure the stable operation of the power system, and the monitoring module 5 monitors the power operation status in real time by collecting the power operation data in real time.
[0020] The control module 4 can use a commercially available power factor compensation controller of model ARC-24 (F) / RL, which has the functions of measuring voltage, current, power factor, reactive power and active power, can display the content of each harmonic, display the operating status of the capacitor and the capacitor groups that can be put into operation, and display the on-off status of each capacitor group; it can perform equal-capacitance switching and proportional switching, can control only reactive power, and can perform comprehensive reactive power control according to the principle of voltage assistance. When the grid voltage is too high or too low, it automatically cuts off the capacitor and alarms and locks. It can automatically resume work after the fault disappears. It has multiple protection functions such as power-on protection, power-off protection, overvoltage protection, undervoltage protection, and undercurrent protection.
[0021] The monitoring module 5 can select the commercially available model AMC16 series data center monitoring instrument, which can monitor the electrical parameters of multiple distribution circuits, can centrally measure and display the bus voltage in the circuit, the current, power, and electric energy of multiple distribution circuits, and can monitor the switch status of each circuit.
[0022] The control module 4 and the monitoring module 5 improve the automation level of the power system, reduce the dependence on manual operation, and achieve comprehensive optimization and upgrading of the power system.
[0023] A temperature and humidity sensor 6 and an air dryer 10 are arranged on the inner wall of the control cabinet body 1. A ventilation duct 7 connected to the control cabinet body 1 is arranged on the top of the control cabinet body 1. A cooling fan 8 is fixedly connected to the ventilation duct 7 through a fixed bracket. Shutters 11 are arranged on both sides of the control cabinet body 1. The output end of the temperature and humidity sensor 6 is electrically connected to the input end of the controller 3, and the output end of the controller 3 is electrically connected to the air dryer 10 and the cooling fan 8.
[0024] The temperature and humidity sensor 6 detects the temperature and humidity values inside the control cabinet body 1, and transmits the data signal to the controller 3. The temperature and humidity ranges are preset on the controller 3. When the humidity parameter value inside the control cabinet body 1 is higher than the preset parameter value on the controller 3, the air dryer 10 is heated to make the humidity inside the control cabinet body 1 reach the set humidity range; after the air dryer 10 is heated, the internal temperature will rise. When the temperature parameter value is higher than the preset parameter value on the controller 3, the controller 3 starts the cooling fan 8 to dissipate the heat inside the control cabinet body 1, thereby realizing the heat dissipation and dehumidification inside the control cabinet body 1.
[0025] The top of the ventilation duct 7 is a sealed end, and an air outlet duct 9 is arranged on the side of the ventilation duct 7. The air outlet duct 9 is connected to the ventilation duct 7.

When the universal wheel 19 is in contact with the ground, it is convenient to move the entire cabinet. When the bottom of the universal wheel 19 is separated from the ground, the bottom of the support block 17 is in contact with the ground, and is used to fix the control cabinet body 1.
[0028] A rubber pad 18 is fixedly connected to the bottom of the support block 17 to achieve a certain degree of buffering and anti-slip. A socket 20 is also provided on the peripheral side of the support block 17. A tool is inserted into the socket 20 to facilitate the rotation of the support block 17.
