Abstract

The invention belongs to the field of power distribution equipment, and particularly discloses an anti-condensation power distribution cabinet, which comprises a closed cabinet body, a condensation removal chamber, a circulating pump and a condensation removal device, wherein a bus compartment, a cable compartment, a circuit breaker compartment and a control compartment are arranged in the cabinetbody, the circuit breaker compartment, the bus compartment, the cable compartment and the condensation removal chamber are communicated in sequence, the input port of the circulating pump is communicated with the output port of the condensation removal chamber, the output port of the circulating pump is communicated with the input port of the circuit breaker compartment, the condensation removaldevice is composed of a compressor, a condenser, a storage tank, a throttle valve and an evaporator which are sequentially communicated, the evaporator is assembled in the condensation removal chamber, a refrigerant medium is arranged in the storage tank, the evaporator and the throttle valve are communicated through a first pipeline, the evaporator and the compressor are communicated through a second pipeline, and the first pipeline and the second pipeline penetrate through the side wall of the condensation removal chamber respectively and are matched in a sealed mode. According to the invention, a dry environment is kept in a power distribution cabinet, no condensation is formed, the insulation creepage distance is increased, short-circuit tripping is avoided, and the power distributioncabinet operates stably and safely.

Description

technical field [0001] The invention relates to a power distribution cabinet, in particular to a power distribution cabinet suitable for anti-condensation, which belongs to the field of power distribution equipment. Background technique [0002] The internal space of medium and high voltage power distribution cabinets is compact and narrow, and the distance between electrical components is small. In humid seasons, such as summer, the air contains more water vapor, which will diffuse into the power distribution cabinet. The air humidity in the power distribution cabinet Increase, the insulating parts, charged body, and the inner surface of the distribution cabinet are easy to form water film in the distribution cabinet. The generation of water film will accelerate the corrosion of the metal body, lead to oxidation of the contact surface, increase the contact resistance, increase the heat generation of the power distribution cabinet, affect the service life of the power distri...
