Spring and summer, rain weather more, the air is more humid, many areas are more humid, humid environment on the safe and stable operation of the indoor enclosed high-voltage switchgear has a great threat, then how to dehumidify the enclosed switchgear?
Conventional methods include: 1) using electric heater, 2) using moisture repellent, 3) using glue to block these methods can solve the problems of moisture and condensation in the cabinet in a short time, but they cannot cure the moisture problem in the cabinet. Because:
1) The electric heater is used to heat the inside of the equipment to solve the condensation phenomenon, but this method cannot fundamentally eliminate the condensation, because this method only increases the degree of unsaturation of the water vapor in the air, and does not discharge the water vapor in the cabinet.
2) with moisture repellent, hanging silicone bags in the cabinet, or other water absorbing materials, but actually because of its limited water absorption effect, and the absorption of water is difficult to discharge, so the effect is often not obvious, the maintenance workload increases.
3) Plugging with glue can only reduce the entry of water vapor and cannot prevent the entry of humid air.
These methods can solve the problems of moisture and condensation in the cabinet in a short time, but they cannot cure the problem of moisture and condensation in the cabinet.
In order to carry out a long-term effective method for the moisture in the cabinet, a SPR-CN-S1 intelligent dehumidifier can be installed in the closed switch cabinet, which is very small in size and can discharge the moisture in the cabinet out of the cabinet through the hose. It can also be dehumidified at low temperatures. To achieve automation, when the humidity in the cabinet exceeds the standard, it will work automatically.
