Device used for terminal box dehumidifying and heating

Abstract

The invention discloses a device used for terminal box dehumidifying and heating. The device is characterized in that the device used for terminal box dehumidifying and heating comprises a terminal box, a temperature and humidity sensor, a temperature and humidity controller, a heating plate, insulating support pillars and a fan; the temperature and humidity sensor and the temperature and humiditycontroller are disposed inside the terminal box; the temperature and humidity sensor is connected with the temperature and humidity controller; the heating plate is mounted at a lower part of the terminal box through the insulating support pillars; and the fan is disposed under the heating plate. The device has the advantages that a silicone rubber heater of the device used for terminal box dehumidifying and heating has the advantages of light weight, small volume, fast temperature increasing, high efficiency and the like, and power loss is decreased; automatic control is carried out according to environmental requirements without the need for on-site manual switching of a staff, and work efficiency of the staff is greatly improved; and the fan and the heater are combined, dehumidifying and heating efficiency is improved, hot air in the box is enabled to form convection, and temperature is more uniform.

Description

technical field [0001] The invention relates to the field of tide-repelling heating devices, in particular to a tide-repelling heating device for terminal boxes. Background technique [0002] At present, when the air is humid, especially in the rainy season, moisture condensation and water accumulation are prone to occur inside transformers, transformer outdoor terminal boxes, and circuit breaker mechanism boxes, resulting in a decrease in the insulation resistance of the DC secondary circuit and rusting of the terminal strips. , It is easy to cause the protection to refuse to operate or malfunction, which seriously affects the safe operation of the power grid. The interior of most substation terminal boxes usually adopts the heater dehumidification method, and the effect is not obvious. Especially when the humidity is high in the rainy season, condensation still occurs frequently; in high temperature summer, the heater will burn the internal equipment of the terminal box; ...

Problems solved by technology

[0002] At present, when the air is humid, especially in the rainy season, moisture condensation and water accumulation are prone to occur inside transformers, transformer outdoor terminal boxes, and circuit breaker mechanism boxes, resulting in a decrease in the insulation resistance of the DC secondary circuit and rusting of the terminal strips. , it is easy to cause protection refusal or malfunction, which seriously affects the safe operation of the power grid

Most substation terminal boxes usually use heater dehumidification method, the effect is not obvious

Especially when the humidity is high in the rainy season, condensation still occurs frequently; in the high temperature time of summer, the heater will burn the internal equipment of the terminal box instead; in the low temperature environment, the heater continues to work, but the temperature inside the terminal box still cannot be raised
