Background technology
In summer especially in plum rain season, wet weather, high fever, the equipment such as inside switch cabinet breaker longtime running can produce
Heat amount, it is final so that the high-low pressure cabinet in electric substation generates condensation.Switchgear degree of protection is higher, heat dissipation ventilation condition compared with
Difference, it is very good and form condensation due to sealing, and be attached to insulating surface and make dielectric accelerated deterioration, cause circuit breaker trip or
Electrical equipment damages.The operation in several years of switchgear linked network, equipment is discharged, and heating problem is very prominent, and a big chunk reason is exactly
Switchgear dehumidifying and cooling effect is not all right.Switchgear is not reached requirement with cable duct closure precision or long-play, inevitable
Moisture is caused to enter from fine gap.If condensation is more serious, it may occur that ionization phenomena, while ozone is generated, to influence
The normal operation of switchgear, or even cause the generation of accident.Therefore carrying out timely cool-down dehumidification to switchgear seems very
It is necessary.
In addition, traditional electric cabinet dehumidification device mostly uses snead process and semiconductor refrigerating method, snead process cannot
Really removal moisture in air, though semiconductor refrigerating method can really remove moisture removal, the air themperature of discharge is relatively low, if condensate
It is not thorough, then condensation can still be occurred by encountering the collector surface in work, influence electric appliance normal work.
