Background
The distribution cabinet (case) is a final-stage device of a distribution system and is divided into a power distribution cabinet (case), a lighting distribution cabinet (case) and a metering cabinet (case). The power distribution cabinet is a general name of a motor control center. The power distribution cabinet is used in the occasions with dispersed loads and less loops; the motor control center is used for occasions with concentrated loads and more loops. They distribute the power of a certain circuit of the upper-level distribution equipment to the nearby loads. This level of equipment should provide protection, monitoring and control of the load.
Complicated changeable because of external environment, when the switch board is inside to receive the tide, and the switch board is inside to cause the temperature higher because electrical equipment's use, and the switch board is inside will form and gather steam and form the condensation, and the condensation will make insulating medium in case adhere to on insulating surface and deteriorate with higher speed, causes circuit breaker tripping operation or electrical equipment to damage, and more serious condition still can cause great electric power accident.
The existing common solutions are as follows:
firstly, an electric heater is used for heating the interior of the equipment to solve the condensation phenomenon, but the method cannot fundamentally eliminate the condensation, and the reason is that the method only increases the unsaturated degree of water vapor in the air, does not discharge the water vapor in the cabinet and also greatly improves the internal temperature of the power distribution cabinet;
secondly, a moisture repellent is used, a silica gel bag or other water absorbing materials are hung in the cabinet body, however, the effect is not obvious and the maintenance workload is increased because the water absorbing effect is limited and the absorbed water is difficult to discharge;
and thirdly, the fan is used for exchanging the convection of air and the external dry air to reduce the humidity in the electrical cabinet, but dust and dirt are easily caused to enter the interior of the electrical cabinet.
Therefore, the moisture protection and the heat dissipation performance in the existing power distribution cabinet are very important, and the normal use of the power distribution cabinet is seriously influenced.
