Moisture-proof and anti-condensation switch cabinet and in-cabinet environment regulation and control method

Abstract

The invention discloses a moisture-proof and anti-condensation switch cabinet, which belongs to the technical field of switch cabinets and comprises a switch cabinet, a monitoring host, an in-cabinetmonitoring module and an air supply device are arranged in the switch cabinet, an out-cabinet monitoring module is arranged outside the switch cabinet, and a heating device is arranged at an air outlet of the air supply device. The in-cabinet monitoring module and the out-cabinet monitoring module respectively comprise a temperature sensor and a humidity sensor; and the in-cabinet monitoring module and the out-cabinet monitoring module are respectively in communication connection with the monitoring host, and the air supply device and the heating device are respectively in communication connection with the monitoring host. The invention further discloses a damp-proof and anti-condensation switch cabinet internal environment regulation and control method, the adopted technical scheme is combined with the regulation and control method, the proper temperature and the dry air environment in the switch cabinet can be guaranteed, and the situation that the performance of equipment in the cabinet is affected due to moisture and condensation aging is effectively relieved.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a moisture-proof and condensation-proof switch cabinet, and also relates to a method for regulating the environment inside the switch cabinet. Background technique [0002] As a power distribution device, the switchgear plays a very important role in the operation of the power grid, and the insulation capacity of the switchgear is an important factor for the safe and stable operation of the switchgear. In addition to being directly determined by the design, material and quality factors of the switchgear, factors such as the temperature, humidity and condensation of the operating environment inside the switchgear will cause the insulation performance of the switchgear to decrease, and eventually develop into breakdown, resulting in ACCIDENT. The decondensation method of the traditional switchgear uses the heater to continuously heat, so that the temperature inside the cab...

Problems solved by technology

This technical solution prevents the moisture in the cable trench from entering the ring network cabinet through the sealing gap by setting an intelligent isolation and moisture-proof treatment chamber, which can reduce the air humidity in the ring network cabinet. The air pressure in the chamber is less than or equal to the auxiliary air pressure of the intelligent isolation and moisture-proof treatment chamber as a condition for pressurization, so there is still a chance for water vapor to escape into the ring network cabinet
