Problems solved by technology

[0003] Nowadays, the commonly used heat dissipation method is to install a high-power axial flow fan inside the cabinet, and open cooling holes, so that the wind blown by the axial flow fan can form an air cooling cycle, and quickly blow out the heat inside the high and low voltage power distribution cabinet. , to achieve the effect of heat dissipation, but the heat dissipation effect of this heat dissipation method is poor and the economy is not good
Especially in summer, due to the long-term operation of the power distribution cabinet equipment, the internal temperature of the cabinet is too high, and it is difficult to dissipate heat, which leads to internal safety hazards, and at the same time causes great damage to the internal parts and components. After a long time of operation, the electrical components inside the power distribution cabinet have a high temperature and the heat dissipation is not smooth, which will affect the operation of the electrical components inside the power distribution cabinet. Long-term high-temperature working environment will accelerate the electronic The aging of components will also reduce the service life of the power distribution cabinet

Abstract

The invention discloses a low-power high-voltage power distribution cabinet with the function of automatically adjusting the ventilation inside the cabinet. The right side of the main casing is fixed with a right ventilation half-shell with an opening facing left, and a fan partition is fixed at a position close to the bottom inside the main casing, and a fan partition is formed between the fan partition and the bottom wall of the main casing. A fan accommodation compartment, the fan accommodation compartment is fixed with a fan, and the rear side of the main housing near the bottom is fixed with an air inlet interface, and the air inlet interface is connected with the air inlet of the fan. According to the parameters of the temperature sensor, it can automatically select natural ventilation for heat dissipation, fan blowing for heat dissipation or use compressed air for heat dissipation, use the reversing plate to switch the air intake mode, and use the temperature sensor to automatically adjust the fan speed to achieve the best air intake and heat dissipation effect The best and more economical and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a low-power high-voltage power distribution cabinet with the function of automatically adjusting the ventilation inside the cabinet. Background technique [0002] High and low voltage power distribution cabinets, because there are many electronic devices installed in the power distribution cabinets, a lot of heat will be generated during operation, which will increase the temperature in the power distribution cabinets. [0003] Nowadays, the commonly used heat dissipation method is to install a high-power axial flow fan inside the cabinet, and open cooling holes, so that the wind blown by the axial flow fan can form an air cooling cycle, and quickly blow out the heat inside the high and low voltage power distribution cabinet. , to achieve the effect of heat dissipation, but the heat dissipation effect of this heat dissipation method is poor and the economy is not...
