No-power outdoor power facility anti-exposure device

Abstract

The invention discloses a no-power outdoor power facility anti-exposure device which comprises a facility body. The no-power outdoor power facility anti-exposure device further comprises an inclined roof and a lower convection hole; wherein the inclined roof is fixedly installed on the upper part of the facility body and completely covers the upper part of the facility body; a drainage gap is arranged between the inclined roof and the upper part of the facility body in the downwardly inclined direction of the inclined roof; the lower convection hole is arranged at the lower part of the surfaceof the facility body and is in communication with the interior of the facility body. The no-power outdoor power facility anti-exposure device solves the problem in the prior art that when in the caseof low outside temperature and high air humidity, the heated air inside a ring main unit rises to the cold top of the ring main unit, because of a large temperature difference between the top of thering main unit and the hot air and the high air humidity, the top of the ring main unit can still condense, the dew is gradually accumulated, mixes with the salt in the air and then flows to the equipment to cause short circuit and malfunction of the equipment in the ring main unit.

Description

technical field [0001] The invention relates to the field of electric facilities, in particular to an anti-dew device for open-air electric facilities without power consumption. Background technique [0002] Open-air power facilities such as ring network cabinets, because they are placed in the open air, the temperature and humidity of the open-air environment often change greatly. When the external temperature is cold, the internal equipment of the ring network cabinet heats the internal air due to the current passing through the heat. When the hot air meets the cold When the wall of the ring network cabinet is closed, because the temperature is lower than its dew point, the inside of the ring network cabinet will condense, and the dew will accumulate and mix with the salt of the air to flow to the equipment, causing the equipment in the ring network cabinet to short-circuit and fail. In order to solve this problem, the existing technology is to open an upper convection hol...

AI Technical Summary

Problems solved by technology

However, the problem with this kind of ring network cabinet is that when the outside temperature is cold and the air humidity is high, the heated air inside the ring network cabinet is heated and rises to meet the cold top of the ring network cabinet. The temperature difference between the hot air is relatively large, and the air humidity is relatively high. The top of the ring network cabinet will still condense. Since the top of the ring network cabinet is flat, the dew will gradually accumulate and mix with the salt of the air and flow to the equipment to make the ring network cabinet The equipment in the cabinet is short-circuited and fails
