Description
Technical field
It is the present invention relates to air drying equipment design field, more particularly to a kind of to be air-dried dress for switch bin
It sets.
Background technology
Switch bin, bus bridge frame power equipment are the most basic power equipments of substation, but with the operation time limit
Increase and part group parts aging aggravation, operational defect or hidden danger are increasingly prominent, hyperbaric chamber generally more focus on ventilation so
Indoor temperature and humidity is affected by outdoor environment, and condensation is also also easy to produce in indoor high-voltage switch gear bin, and cabinet interior insulation material is big
It is more not consider water proofing property, its insulating properties can be reduced if having dew on it, in some instances it may even be possible to cause to climb electricity or flashover, seriously
Equipment normal operation is influenced, the equipment especially having is in stoppage in transit state, and internal temperature is lower, is more easy to be formed on its surface solidifying
Dew, easily occurs accident if power transmission at this time.
It is generally used for dehumidification by condensation in the mating heater of moisture probe or the small-sized cabinet of fan in the power system at present
Device.They are all to start hot dehumidification by condensation device in heater/small-sized cabinet when humidity is excessively high, will be in humid air heating/cabinet
Humid air is condensed into outside droplet discharge cabinet, but no matter which kind of mode will appear the situation of heating equipment ambient air,
Hot-air can be caused to rise.Condensation is will produce after encountering the cold damp air of top of the box after hot-air rising, condensation makes absolutely instead
Edge level reduces, and causes the safe operation for being unfavorable for equipment, because in switch bin being the space of relative closure.Cause there is still
Most residual moisture can not thoroughly be effectively reduced bin equipment interior humidity inside bin.In south, summer temperature
Degree is high, and humidity is big, in addition the heat that operating element generates in bin, the formation of condensation cause various cable skin agings serious,
Easily cause equipment fault or even equipment burnout phenomenon.The equipment such as above-mentioned heater damage has yields or service life eventually
Problem, must have a power failure after sale after failure just can carry out.But it is influenced than more serious because high-tension apparatus has a power failure, difficulty compares
Greatly, and moist dew condensation phenomenon after losing heating device is caused to aggravate.The temperature and humidity measurement point of the equipment such as above-mentioned heater is general
There are one only, but what high pressure complete switch bin inside generally can be general thinks to be divided into cable vault, breaker chamber, busbar
4 room, secondary chamber regions.And current heating equipment generally can only control heating equipment by measuring the humidity in a region
Whether work.The mode of heating of the equipment such as above-mentioned heater causes heated spatial concentration, and air themperature is uneven, actual drying
Effect is very limited, and the non-uniform temperature of space air exacerbates dew condensation phenomenon.It is above-mentioned by way of condensing unit, water
Pearl can be transported from cable duct below switch bin to outdoor, but the pipeline external surface for transporting cold water all can condensation.Higher
In the high-tension apparatus of voltage class, the pipeline of cold water is transported when failure because class of insulation problem there is a possibility that electrification, increase
New security risk.
