Description

Technical Field

[0001] The utility model relates to the technical field of reactive power compensation devices, in particular to a reactive power compensation device. Background Art

[0002] Reactive power compensation, also known as reactive power compensation, is a technology that improves the power factor of the power grid, reduces the loss of power transformers and transmission lines, improves power supply efficiency, and improves the power supply environment in the power supply system. Therefore, reactive power compensation devices play an indispensable and important role in the power supply system. Reasonable selection of compensation devices can minimize the loss of the power grid and improve the quality of the power grid.

[0003] Existing reactive power compensation devices generally use air cooling for heat dissipation and cooling. That is, a fan is used to blow air to the heat-generating components in the reactive power compensation device, and the air flow inside and outside the reactive power compensation device is used to circulate to remove the heat. However, dust will be brought in during the air circulation. Long-term use of this cooling method will cause dust to gradually accumulate on the surface of the components, reducing their working performance and service life. Therefore, we propose a reactive power compensation device. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. The existing reactive power compensation device generally adopts air cooling for cooling when performing heat dissipation and cooling. That is, a fan is used to blow air to the heat-generating components in the reactive power compensation device, and the air flow inside and outside the reactive power compensation device is used to circulate to take away the heat. However, dust will be brought in during the air circulation. Long-term use of this cooling method will cause dust to gradually accumulate on the surface of the components, reducing their working performance and service life.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0013] As a preferred solution of the present invention, the output end of the water pump is connected to the diverter pipe, the diverter pipe is connected to the atomizing nozzle, and the output end of the atomizing nozzle faces the heat exchange cover when installed.

[0014] The technical effect of adopting the above further scheme is: by connecting the output end of the water pump with the diverter pipe and the diverter pipe with the atomizing nozzle, the water pump can extract the water inside the water tank and send it to the atomizing nozzle through the diverter pipe, so that the atomizing nozzle can atomize the water and spray it out. By facing the output end of the atomizing nozzle towards the heat exchange cover during installation, the water mist sprayed by the atomizing nozzle can adhere to the outer wall of the heat exchange cover to perform heat exchange and cooling of the heat exchange cover.

[0015] As a preferred solution of the present invention, a water inlet is provided at the top of the water tank, and the water inlet is communicated with the interior of the water tank.

[0017] As a preferred solution of the present invention, an observation plate is installed on the outer side wall of the water tank, and a scale bar is fixed on the outer side wall of the water tank corresponding to the observation plate.

[0018] The technical effect of adopting the above further solution is: through the design of the observation plate and the scale bar, the staff can directly and clearly observe the remaining water volume inside the water tank, so as to add water in time.

[0019] As a preferred solution of the present invention, a dustproof net is fixed on the inner wall of the device box near the fan, and the dustproof net is made of stainless steel.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] In the present invention, through the design of the heat exchange cover, heat exchange tank, water tank, water pump, atomizing nozzle and fan, when it is necessary to dissipate heat and cool down the interior of a reactive compensation device, the water pump can be turned on. After being turned on, the water pump will extract water from the water tank and send it to the diversion pipe. After being diverted by the diversion pipe, the water will be evenly atomized and sprayed out through the atomizing nozzle. The sprayed water mist will adhere to the outer wall of the heat exchange cover and the inner wall of the heat exchange tank. The fan is turned on and the fan will drive air circulation to help the water mist evaporate faster. The water mist on the outer wall of the heat exchange cover and the water mist on the inner wall of the heat exchange tank will absorb the heat of the heat exchange cover when evaporating, so as to dissipate heat and cool down the heat exchange cover, thereby cooling the electronic components on the mounting rack.
