Rotary dehumidifier-type condensation dehumidification device for metal-clad equipment and control method of rotary dehumidifier-type condensation dehumidification device

Abstract

The invention discloses a rotary dehumidifier type condensation dehumidification device for metal armored equipment and a control method thereof. The device includes a rotary dehumidifier, a ventilation unit and an automatic condensation dehumidification controller; On the installed equipment, it is connected with the rotary dehumidifier through the air inlet pipe and the return air pipe; the device has a simple structure and a high degree of automation, which realizes the automatic remote control of the condensation of the metal armored equipment and greatly reduces the opening time of the dehumidification equipment. Avoid the fire risk caused by overheating of the dehumidification equipment inside the metal armored equipment; the internal humidity control of a single metal armored equipment is relatively uniform, and the humidity target value can be set arbitrarily, avoiding the phenomenon of uneven dehumidification inside the large-volume metal armored equipment , the dehumidification effect is good; the dehumidification process will not cause the internal temperature of the metal armored equipment to rise, avoiding the risk of excessive aging of the insulating material.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and relates to a rotary dehumidifier type condensation dehumidification device for metal armored equipment and a control method thereof. Background technique [0002] When the temperature of metal armored equipment (high-voltage switchgear, HSBC, ring network cabinet, etc.) drops suddenly, condensation will often appear on its internal equipment, the insulation strength of electrical components will be greatly reduced, and a short circuit fault will occur. The phenomenon is more common in the humid climate areas in southern my country, and has become one of the serious threats to the safe and stable operation of the power system. [0003] The current condensation dehumidification method for metal armored equipment is generally to install an electric heater inside to increase the internal temperature and avoid condensation of water vapor. There are problems: 1) The electric heating d...

Problems solved by technology

[0003] The current condensation dehumidification method for metal armored equipment is generally to install an electric heater inside to increase the internal temperature and avoid condensation of water vapor. There are problems: 1) The electric heating device has been put into operation for many years and consumes a lot of electric energy. Poor economy; 2) When the temperature is high, the internal temperature of the metal armored equipment will be too high, shortening the service life of the insulating material; 3) The electric heating dehumidification device can only be arranged in a part of the metal armored equipment, and the internal temperature distribution Uneven, the larger the internal space, the worse the heating effect and the worse the dehumidification effect; 4) The aging speed of the electric heating device is faster, and there is a greater risk of fire
