Switch cabinet heat dissipation device for transformer substations in cold regions

Abstract

The invention relates to the field of substation switch cabinets, in particular to a switch cabinet heat dissipation device for transformer substations in cold regions. The device comprises a device body, and a heating plate is fixedly mounted at the lower end in the device body. A fitting block is movably mounted in the inner wall of the lower end of the device body. A moving plate is movably mounted outside the lower end of the device body, and an air inlet groove is formed in the moving plate. The lower end of the heating plate is inverted V-shaped, and when a fan is started and external air enters the device body through an air inlet channel, the external air can be in contact with the heating plate which is heated to above zero DEG C, therefore, the overall temperature of the airflowentering the device body is increased, and damage caused by too low temperature during contact with the internal electrical elements of the device body is avoided. Meanwhile, through an inclined surface at the lower end of the heating plate, water vapor generated during heating of cold air flow can be condensed at the lower end of the heating plate, so that water generated during heating of cold air cannot be in contact with the electrical elements in the device body.

Description

technical field [0001] The invention relates to the technical field of substation switch cabinets, in particular to a cooling device for switch cabinets used in substations in cold regions. Background technique [0002] A substation is a place in a power system that transforms voltage and current, receives electric energy and distributes electric energy. The substation in the power plant is a step-up substation, whose function is to boost the electric energy generated by the generator and feed it to the high-voltage power grid, while the outdoor substation mostly converts the high-voltage power in the power grid into low-voltage power for daily use in factories and communities. use. [0003] However, most of the switchgears in the existing outdoor substations are not equipped with cooling devices for the cold regions in the north, so that the electrical components in the switchgear will be in contact with the air below zero for a long time when cooling, which will easily ca...

Problems solved by technology

[0003] However, most of the switchgears in the existing outdoor substations are not equipped with cooling devices for the cold regions in the north, so that the electrical components in the switchgear will be in contact with the air below zero for a long time when cooling, which will easily cause damage to the electrical components, and At the same time, there is no cleaning structure for the air inlet filter, so the air inlet is easy to be blocked in the season when the wind and sand in the north are large, which greatly increases the maintenance cost
