[0002] The power grid needs to provide corresponding reactive power to these devices during the operation of inductive loads. After installing reactive compensation equipment in the power grid, it can provide reactive power consumed by inductive reactance, reducing the reactive power provided by the power grid to the inductive load and transmitted by the line. Since the flow of reactive power in the power grid is reduced, the energy loss caused by the transmission of reactive power in the line and transformer can be reduced. This is reactive compensation.

[0003] During the actual operation of the reactive power compensation cabinet, the heat dissipation method in the prior art cannot dissipate the heat of the electronic equipment in the reactive power compensation cabinet in a timely and effective manner, resulting in the equipment continuously running at high temperatures, being prone to aging, and being prone to failure.

[0009] Furthermore, a temperature sensor and a humidity sensor are respectively installed at the bottom of the heat dissipation cavity, and the temperature sensor and the humidity sensor are respectively electrically connected to a controller, and the controller is arranged on the inner wall of the cabinet.

[0023] like Figure 1-5 As shown, a reactive power compensation cabinet cooling system comprises a heat dissipation cavity 1, a water cooling module, an air cooling module and an exhaust fan 2; in this embodiment, a refrigeration cavity is arranged at the top of the cabinet 13 of the reactive power compensation cabinet involved in the present application, a dehumidification layer 3 is formed in the upper part of the refrigeration cavity, and a cold air outlet connected with the heat dissipation cavity 1 is arranged at the lower part; the bottom of the refrigeration cavity is connected with the heat dissipation cavity 1, the heat dissipation cavity 1 is arranged in the upper part of the cabinet 13, and a mounting plate 5 is arranged at the front side of the heat dissipation cavity 1; and preferably, protective doors are arranged at the front and rear sides of the cabinet 13, and the cabinet 1 A bracket 14 is provided on the inner bottom wall near the rear protective door for mounting the capacitor; slide rails 4 are provided at intervals on the mounting working surface of the mounting plate 5 for mounting corresponding electronic components, and the front and rear protective doors are opened to facilitate the inspection of the internal components of the cabinet 13; it should be noted that a connecting port 15 is provided between adjacent slide rails 4, and the connecting port 15 is connected to the heat dissipation cavity 1, and the cold air is discharged through the connecting port 15 to the electrical components of the guide rails to quickly dissipate the heat of the electrical components.

[0024] Specifically, in this embodiment, the heat dissipation chamber 1 is arranged on the rear side of the mounting plate 5, and the top end is connected to the refrigeration chamber; the water cooling module is connected to the heat dissipation chamber 1, and the corresponding water cooling and heat dissipation operation is performed inside the heat dissipation chamber 1; wherein the water cooling module includes a confluence chamber 6, which is respectively arranged between the upper and lower walls in the heat dissipation chamber 1; a plurality of refrigeration pipes 7 are arranged, which are respectively connected between the upper and lower confluence chambers 6; a water tank 8 is fixed on the rear side wall of the heat dissipation chamber 1, and water is circulated between the upper and lower confluence chambers through a water pump 9 and a connecting pipeline, a return pipe 10 is arranged between the upper confluence chamber 6 and the water tank 8, and the water pump 9 is respectively connected to the lower confluence chamber 6 and the water tank 8 through a pipeline, and after starting the water pump 9, the water in the water tank 8 can be pumped into the lower confluence chamber 6 and enter the refrigeration pipe, the water in the water tank 8 is a water body such as a coolant or water, and the refrigeration pipe is inside the heat dissipation chamber 1, and the internal water absorbs heat to perform corresponding water cooling and heat dissipation. wherein, preferably, the water pump 9 is fixed between the two sides of the cabinet 13 by fixing rods on both sides.

[0025] In some preferred embodiments, the air cooling module includes a refrigeration unit and an air supply unit, both of which are arranged at the top of the cabinet 13. The refrigeration unit is connected to the air supply unit, and is used to deliver airflow from the air supply unit for cooling and cooling; the exhaust fan 2 is arranged at the lower part of the side walls of the reactive compensation cabinet 13, and is used to extract the airflow in the cabinet 13 from the lower sides of the lower cabinet 13. Among them, the refrigeration module can be a refrigeration device such as a refrigeration plate (it should be noted that the heat dissipation end of the refrigeration plate needs to be provided with a corresponding heat dissipation unit for heat dissipation of the heat dissipation end of the refrigeration plate). The refrigeration unit is used to cool the airflow in the refrigeration cavity, and the air supply unit is used to output the airflow in the refrigeration cavity; after starting the air cooling module, if the refrigeration unit and the air supply unit are started at the same time, cold air can be sent into the heat dissipation cavity 1. If only the air supply unit is started, it can cooperate with the exhaust fan 2 to form a ventilation path between the upper and lower parts of the cabinet 13 to ventilate and dissipate heat inside the cabinet 13.

When the temperature is not too high (taking the starting temperature of temperature range 2 as an example, which is lower than the starting temperature of temperature range 1, the temperature is not too high when the detected temperature is within temperature range 2 and does not reach temperature range 1), the controller receives the data transmitted by the temperature sensor 11, starts the air supply unit, the water cooling module and the exhaust fan 2, and performs water cooling and ventilation heat dissipation inside the cabinet 13; when the detected temperature is high, the controller starts the refrigeration unit, the air supply unit, the water cooling module and the exhaust fan 2, and performs water cooling and air cooling heat dissipation inside the cabinet 13. The refrigeration pipe is located on the path of cold air discharge to improve the heat dissipation efficiency.
