Electric control cabinet with dehumidification function

Abstract

The invention relates to an electric control cabinet with a dehumidification function. The electric control cabinet comprises a cabinet body, and is characterized in that an inversed V-shaped top cover is arranged at the top of the cabinet body; thermal baffles are arranged on two side plates of the inversed V-shaped top cover; a water guiding groove is formed in the edge of the bottom end of the inversed V-shaped top cover; outriggers are arranged at the bottom of the control cabinet and fixed on a base plate of the floor; an air suction funnel is arranged in the cabinet body and connected with a pipeline; the pipeline is connected with a draught fan; a moisture absorption cavity and a drying cavity are arranged in the pipeline in sequence; a moisture absorption layer is arranged in the moisture absorption cavity; an electric heater strip is arranged in the drying cavity; the electric heater strip and the draught fan are connected to a power supply through an electromagnetic relay; the electromagnetic relay is connected with a controller; and the controller is connected with a humidity sensor which is arranged in the control cabinet.

Description

technical field [0001] The invention belongs to the technical field of power equipment, and relates to a power control cabinet, in particular to a power control cabinet with a dehumidification function. Background technique [0002] The power control cabinet is an important part of the power system and plays a very important role in the entire power grid transmission process. [0003] With the continuous development and progress of economic construction, more and more power control cabinets are built in the open air environment. The power control cabinets in the open air environment for a long time are easily affected by the outside world, resulting in moisture inside the power control cabinet. As a result, various power devices in the power control cabinet cannot work normally, affecting the normal power transmission of the entire power grid. [0004] In addition, although the neutral point of the distribution cabinet in the prior art adopts the operation mode of grounding...

[0003] With the continuous development and progress of economic construction, more and more power control cabinets are built in the open air environment. The power control cabinets in the open air environment for a long time are easily affected by the outside world, resulting in moisture inside the power control cabinet. As a result, various power devices in the power control cabinet cannot work normally, affecting the normal power transmission of the entire power grid

[0004] In addition, although the neutral point of the distribution cabinet in the prior art adopts the operation mode of grounding through resistance, it only plays the role of grounding and does not issue an alarm, so that the staff cannot obtain the alarm information in time; this is the prior art inadequacies of
