The invention provides a power distribution cabinet, and power distribution equipment using the same, and belongs to the technical field of electrical cabinets. The power distribution cabinet comprises a cabinet body, wherein a top cover is arranged at the upper end of the cabinet body; a ventilation water-locking film used for allowing air in the cabinet body to pass through and blocking water from entering the cabinet body is arranged in the cabinet body; the ventilation water-locking film is located below the top cover and arranged at an interval with the top cover; and the cabinet body isfurther provided with a water outlet used for enabling water blocked by the ventilation water-locking film to flow out of the cabinet body, so that water vapor in the cabinet body cannot enter the cabinet body through the ventilation water-locking film. According to the power distribution cabinet, the structure is relatively simple, and the problem that an anti-condensation device in the prior artis relatively complex is solved.
Description
technical field [0001] The invention relates to a power distribution cabinet and power distribution equipment using the power distribution cabinet. Background technique [0002] The condensation problem of outdoor power distribution equipment is very common. The moisture condensation of the equipment will cause corrosion to the cable terminal head in the cable room and the operating mechanism in the switch room, and the insulation capacity will decrease. If such problems exist for a long time, it may cause partial discharge and flashover. The situation seriously affects the safe operation of the equipment. In recent years, the faults caused by the moisture and condensation of power distribution equipment have become one of the main reasons for the tripping of distribution network lines. The existing methods to deal with the condensation problem include heating method, condensation method, and ventilation method. Generally, control devices and sensing measures need to be ins...
