Description
Technical field
The present invention relates to field of power electronics, in particular, relate to a kind of method that solves the switch cubicle condensation.
Background technology
For switch cubicle; The metalwork surface temperature drops to dew point temperature when following in the cabinet, and the metal surface can form the globule, and this phenomenon becomes condensation; Whether condensation depends on ambient temperature, and in-cabinet temperature and several variable quantity such as relative humidity, dew point temperature determine.Dew point temperature is meant in the air of uniform temperature; The maximum level of steam becomes " saturated vapor amount "; The air of this moment becomes " saturated air ", and when saturation air temperature descends, airborne steam will condense into the globule; Contain the saturation of the air temperature of steam, become dew point temperature.The factor that forms condensation in the switch cubicle easily mainly by: (1) area surroundings temperature is high, and temperature Change is big, is prone to the condensation in the metal surface during cold and hot air exchange; (2) switch cubicle bottom is moist, even the cable trough that has has ponding, during water evaporation, when being lower than in the cabinet air themperature like metallic surface temperature, forms condensation in the metal surface; (3) equipment that has is in shut down condition, and in-cabinet temperature is lower than ambient temperature through regular meeting, causes that the metal surface has the globule to condense.
To above-mentioned phenomenon; China adopts automatic heating and dehumidification controller to prevent that the existing more than ten years of condensation are historical in switch cubicle; This heating and dehumidification controller guarantees that at anti-moist, anti-condensation the high-tension apparatus reliability service has played positive role, but in use in some area, problem also occurred.Automatic heating device only adds having heaters in bottom, circuit storehouse at present; Control heating through a humidity controller, and bus storehouse and switch storehouse there is not heater, do not have humidity controller yet; And the totally-enclosed nontransparent no inspection hole of switch cubicle; The tour personnel can't observe directly inner case, and this just greatly reduces whole condensation control ability in the cabinet, causes electrical equipment fault; Inner because the condensation phenomenon of switch cubicle can not good treatment in high humidity area; Its built-in electrical insulation level is low, can't the assurance device reliably working, therefore; When firing equipment or temperature and humidity controller break down; Can only keep in repair by power operation, reduced the power equipment reliability of operation greatly, reduced the safe operation of whole electrical network.
Therefore; Improve the whole condensation control ability in the switch cabinet, but and when breaking down power-on serving, reduce the electrical equipment fault possibility; Strengthen the power equipment reliability of operation, the safe operation ability that improves whole electrical network is those skilled in the art's problem demanding prompt solutions.
Summary of the invention
