Intelligent power distribution cabinet and method for monitoring power distribution cabinet

Abstract

The invention belongs to the technical field of power distribution cabinets and relates to an intelligent power distribution cabinet and a method for monitoring the power distribution cabinet. After a fan preassembled on the power distribution cabinet runs for a long time, dust and impurities are doped into the fan through heat dissipation seams in the power distribution cabinet to cause blockage, and as a result, the heat dissipation performance is weakened, and the cleanliness in the power distribution cabinet is reduced. According to the intelligent power distribution cabinet and the method for monitoring the power distribution cabinet, through a diaphragm plate arranged in an insulating shell, the cavity space of a cooling water solution is changed under the driving of an oil cylinder, the cavity pressure of the cooling water is changed; when the cooling water absorbs the heat of a heat conduction plate, the cooling water solution is in a state similar to adiabatic expansion; after the cooling water solution flows back, the volume of the diaphragm plate is compressed and recovered in the insulating shell, so that a heat effect process similar to adiabatic expansion in the Carnot cycle is achieved; and therefore, the heat exchange ratio of the cooling water solution is increased, the temperature control effect in the cabinet body is ensured, and therefore, the operation effect of the intelligent power distribution cabinet is improved.

[0003] After the power distribution cabinet detects that the temperature of its internal components reaches the warning threshold condition, it will enter the power-off protection state, which will interfere with the operation of the electrical equipment on the power distribution cabinet line, and the pre-installed fan on the power distribution cabinet will , the heat dissipation seam on the power distribution cabinet will be doped with dust and impurities to cause blockage, which will weaken the heat dissipation performance and reduce the cleanliness inside the power distribution cabinet, and install the power distribution cabinet in the low-temperature indoor environment of the air conditioner, which increases the power distribution. The cost of cabinet construction, and the temperature difference stratification will be formed in the indoor environment. In order to control the temperature rise of components at higher positions inside the power distribution cabinet, the increased cooling capacity increases the operating cost of the power distribution cabinet.

[0004] There are also some technical solutions about intelligent power distribution cabinets and methods of monitoring power distribution cabinets in the prior art. For example, a Chinese patent with application number CN201910813060.8 discloses an intelligent monitoring type high and low voltage power distribution cabinet and its monitoring The method includes a cabinet body, a composite rotary power distribution equipment rack, a wind direction tracking air-cooled heat dissipation device, a fire extinguishing device, and a terminal in a general control room; the composite rotary power distribution equipment rack includes a rotating shaft frame, a first servo motor, and an electrical component mounting plate , the second servo motor; the side view monitoring probe is used to monitor the electrical components on the multiple electrical component mounting boards stacked from the side viewing direction; the second servo motor drives the corresponding electrical component mounting board to rotate to the top view monitoring The probe is directly below the probe, so that the monitoring probe can monitor the electrical components on the electrical component mounting board from the overlooking direction; the intelligent monitoring type high and low voltage power distribution cabinet and its monitoring method provided by this technical solution can monitor more comprehensively and effectively ensure the high and low voltage distribution cabinet. The working safety of the electrical components in the electric cabinet; however, the interior of the power distribution cabinet adopted by this technical solution will be mixed with dust and impurities in the external environment, which will affect the accuracy of monitoring the parameters of the power distribution cabinet
