Description
Technical field
The utility model belongs to electric equipment field, relates in particular to the moistureproof regulator cubicle of a kind of air pressure balanced-type.
Background technology
Regulator cubicle is to be processed by steel matter etc., is used for protecting the cupboard of the normal work of electronic devices and components, is widely used in chemical industry, environmental protection industry (epi), nuclear power industry, transportation industry, hydropower industry.
In electric operation process in regulator cubicle, can produce amount of heat, the temperature in enclosed electrical cabinet is raise; In electric closing process in regulator cubicle, the temperature in regulator cubicle reduces.So just cause the temperature in regulator cubicle often to fluctuate.And regulator cubicle external temperature, with season, while changing round the clock, also can cause the fluctuation of temperature in regulator cubicle.Temperature in regulator cubicle raises and reduces, and can make accordingly air pressure wherein increase and reduce, so the frequent fluctuation of temperature can make wherein air pressure often fluctuate in regulator cubicle.Cable enters the sealing plug at regulator cubicle base plate place or other potted components understand because the frequent fluctuation of pressure in regulator cubicle, occur that sealing effectiveness is bad, even directly come off, thereby cause humid air to enter in regulator cubicle, finally make the life-span of electric equipment greatly shorten.
