Anti-condensation ring main unit

Abstract

The invention discloses an anti-condensation ring main unit, which comprises a box body with an air inlet and an air outlet formed in the side wall; an air inlet assembly; an air blowing assembly which is arranged in the box body and has a hot air mode and a natural air mode, wherein the air blowing assembly abuts against one end of a piston and can drive the piston to do reciprocating motion along the air inlet in the moving process, and the piston can seal the box body when stopping working, so that the box body becomes a closed space; an exhaust assembly communicating with the exhaust port;a driving assembly used for driving the blowing assembly to move; a control assembly used for driving the air blowing assembly to move and a control assembly. The air blowing assembly is linked withthe air inlet assembly. When; the box body is de-humidified, the air inlet is automatically opened. After dehumidification is completed, the air inlet is automatically closed, external humid air is prevented from entering the box body through the air inlet, the rotary vane vacuum pump is arranged, air in the box body can be exhausted, the humid air outside the box body cannot enter the box body from the exhaust port, it is guaranteed that the air humidity in the box body is kept at a low level, and therefore the condensation phenomenon is avoided.

Description

technical field [0001] The invention relates to the field of ring network cabinets, in particular to an anti-condensation ring network cabinet. Background technique [0002] The ring network cabinet is a kind of electrical equipment, which is divided into indoor type and outdoor type. The outdoor type ring network cabinet works outdoors for a long time. In rainy and snowy weather and when the air humidity is high, the ventilation effect is poor or the sealing degree is not good. Condensation usually occurs inside the cabinet, which is likely to cause short-circuit accidents and increase the risk of electrical equipment. The existing ring main unit uses heating and ventilation to prevent condensation; the inventor found that the existing The technology has the following defects: the airtightness of the ring network cabinet's vents is not good enough, so that rainwater or humid air can enter through the vents, which in turn leads to condensation in the box.
