Description
Technical field
The utility model is related to a kind of electric power cabinet dehumidification devices.
Background technology
Distribution box long-term work is in spacious environment, and air is relatively closed in cabinet, and moisture cannot be discharged in time after entering, pole
Easily in cabinet and electronic component surface generates dew condensation phenomenon, this phenomenon can lead to Railway Project：1）Cause short circuit and short-circuit thing
Therefore；2）Electronic component corrosion is bad so as to cause wiring circuit contact；3）Instrument malfunction, table is caused to show the problems such as inaccurate.The master of condensation
Reason is wanted there are three aspects：When raining, rainwater flows into cable duct, and the humid air in cable duct, which enters, forms dew condensation phenomenon in cabinet；
When raining and ambient humidity is high, the dew condensation phenomenon of wiring terminal box is even more serious, is formed in cabinet door and internal unit solidifying
Dew forms major safety risks to the safety of High-Voltage Electrical Appliances；When reflecting winter according to substation staff on duty, what condensation was formed
Water when weather temperature increases, and is evaporated to steam in inner icing, in suitable temperature, and starts condensation.
Currently, the anti-condensation means of cabinet producer are generally taken controls the method for heater to prevent from coagulating by condensation sensor
The generation of dew.A condensation-preventing controller is filled in control room, when the condensation signal that monitoring control devices to sensor are sent, immediately
Start heater heating.After condensation is eliminated, controller then closes heater.For from principle, this is that a kind of anti-condensation have
Effect measure.But first, existing condensation sensor is all passive-type action, humidity is very big in air sometimes, but since condensation passes
Sensor does not form condensation also, and therefore, heater will not start, and must have certain amount of lagging when condensation occurs.From anti-
Condensation as the anti-accident important measures of switchgear for, restart heating close to the edge of condensation eliminate condensation lack one it is pre-
Anti- process：Second, the characteristic defective that condensation sensor is intrinsic, insensitive to relative humidity variations,：Third, since condensation senses
Device can change sensitivity after the chemical attacks in by koniology or moisture content, and anti-condensation control point is caused deviation occur,
At this moment anti-condensation reliability can be reduced, the security reliability of switchgear is also reduced.It is thus impossible to directly use condensation sensor
To control the starting for driving damp controller.To ensure that the safe operation of network system, the long-life of electrical equipment safely and effectively make
With electric system proposes requirements at the higher level to moisture-proof, anti-condensation in cabinet.
