Embodiment 1

[0038] Example 1, as Figure 1-3 As shown, when the gas circulation efficiency in the cabinet 1 is relatively slow, the blower 804 can be activated through the control panel 3, and the guide gas is blown into the ventilation cavity 803 through the output of the blower 804, and the air is removed from the filter according to the output of the gas. The net 8 and the vent 801 seep out, blowing away the dust and particles that hinder the gas circulation in the filter 8 and the vent 801, and at the same time improve the guiding of the heat dissipation gas inside the cabinet 1, and speed up the gas circulation efficiency.

Embodiment 2

[0039] Example 2, as Figure 1-7 As shown in the figure, when there is a large amount of moisture in the cabinet 1, the electric heating wire 405 can be activated through the control panel 3, and the water in the U-shaped water tank 6 can be heated by the electric heating wire 405. Start to guide the heated water from the diversion pipe 404, and evenly discharge the diversion air from the exhaust holes 407 through the activation of the two sets of cooling fans 401, and then cooperate with the heat source generated by the heated water circulating in the diversion pipe 404, Promote the conversion of heat dissipation gas into drying gas, so that the humidity in the device can be dried and eliminated, and the functionality of the device can be increased.

[0040] Working principle: When the device is in use, the power monitor 12 is connected to the power distribution system in parallel for real-time monitoring, and the power is controlled by the parallel connection of two groups o...

Abstract

The invention discloses an adaptive modularized intelligent low-voltage reactive power compensation device, which comprises a cabinet body. Capacitor banks are arranged on the top of both sides of one end of the front of the board, a fuse is arranged at the middle of both sides of the front of the installation board, and a control panel and a power controller are respectively arranged at the bottom of both sides of the front of the installation board. The top inside the cabinet body is provided with a crossbeam; the present invention uses the power monitor and the installation board as the installation body, and two groups of reactive power compensation modules, capacitor banks and fuses are symmetrically assembled and connected in parallel on both sides, and the matching center is The bushings at the separation point correspond to each other, so that the two sets of compensation mechanisms can evenly obtain the heat dissipation and dehumidification effect, ensure the current flow and power components are more stable, reduce the output loss of the compensation mechanism, and increase the service life and compensation efficiency of each component.

Description

technical field [0001] The invention relates to the technical field of electric power supply, in particular to an adaptive modular intelligent low-voltage reactive power compensation device. Background technique [0002] The power output by the grid includes two parts: one is active power: directly consumes electrical energy, converts electrical energy into mechanical energy, thermal energy, chemical energy or sound energy, and uses these energy to do work; the other is reactive power: consumes electrical energy, but only converts electrical energy into electrical energy. Converted to another form of energy, this energy is a necessary condition for electrical equipment to perform work, and this energy is periodically converted with electrical energy in the power grid, this part of power is called reactive power, reactive power. Compensation, the full name of reactive power compensation, is a function of improving the power factor of the power grid in the power supply system,...
