Description
Technical field
The present invention relates to a kind of electric power cabinet dehydrating units.
Background technology
Distribution box long-term work is in spacious environment, and air is relatively closed in cabinet, and moisture cannot discharge in time after entering, pole
Easily in cabinet and electronic component surface generates dew condensation phenomenon, this phenomenon can cause 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）Cause instrument malfunction, table shows 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 is evaporated to steam in inner icing, weather temperature rise, in suitable temperature, and starts condensation.
At present, the anti-condensation means of cabinet producer are generally taken by the method for condensation sensor control heater to prevent from coagulating
The generation of dew.Fill a condensation-preventing controller in control room, during the condensation signal that monitoring control devices to sensor are sent, immediately
Start heater heating.After condensation eliminates, 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 be when condensation occurs, that is, have certain amount of lagging.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, also reduces the security reliability of switchgear.It is thus impossible to directly use condensation sensor
To control the starting for driving damp controller.To ensure the safe operation of network system, the long-life of electrical equipment safely and effectively makes
With electric system proposes requirements at the higher level to moisture-proof, anti-condensation in cabinet.

Block.
As a further improvement on the present invention, the inner cabinet is insulating heat-conductive material.
As a further improvement on the present invention, the inner cabinet is ceramic material.
Compared with prior art, having the beneficial effect that acquired by the present invention：
The present invention possesses the characteristics of simple in structure, easy to operate and reliable, and the present invention is using two temperature sensors, one
Cabinet body temperature is surveyed, one is surveyed the outer temperature of cabinet, while heater is utilized to adjust in-cabinet temperature.The temperature inside cabinet is made to begin
Environment temperature certain outside switchgear is kept above eventually, is begun by the controller of CPU intelligent controls by the temperature of inside switch cabinet
It is 2 DEG C ~ 4 DEG C higher than switchgear external environment eventually, it is allowed to not generate the condition of condensation generation, plays pre- anti-condensation effect.Work as switch
Cabinet external environment is 2 DEG C high ~ 4 DEG C of temperature when just stop heating.Since ambient volume is small in switchgear, reach adding needed for this temperature difference
Thermal power is smaller, in addition, running switchgear has heat generation in itself, can also be used as a part for heating power.This
Sample can not only be effectively prevented inside switch cabinet and condensation occurs, and can be greatly energy saving.In order to improve it is moisture-proof,
Anti-condensation reliability, another measure are the relative humidity sensors added in each device in linear measurement switchgear, are controlled
Device processed also measures the relative humidity in display case, according to temperature, the temperature difference and relative humidity pa come differentiate inside cabinet by tidal excursion
Degree, starts heater, and adjusting switch in-cabinet temperature further improves and drives damp and anti-condensation ability.The program is also in controller
Communication module is equipped with, by the relative humidity teletransmission computer in cabinet internal and external temperature, the temperature difference and cabinet, carries out data record, with
It is convenient for the analysis of data and the adjustment of setting value.Dew condensation phenomenon can just prevent completely.
