Abstract

The invention discloses an outdoor cabinet anti-condensation device. The outdoor cabinet anti-condensation device comprises a remote computer, a host and a plurality of subs. The remote computer is connected with the host through network; the host and the subs are connected and communicated through wireless RS485 (recommended standard 485); the host comprises a host power source module, a host wireless RS485 module, a display screen, an operating state indicating lamp array and an industrial control module for obtaining measurement data and operating state of the subs and controlling the operating state indicating lamp array, wherein the host power source module, the host wireless RS485 module, the display screen and the operating state indicating lamp array are all connected with the industrial control module; every sub is composed of a sub power source module, a sub wireless RS485 module, a humidity and temperature sensor, a heater and a single chip microcomputer. The outdoor cabinet anti-condensation device is convenient to mount and replace, low in power consumption and heat emission, dustproof, waterproof, stable and reliable.

Description

technical field [0001] The invention relates to the field of substation equipment maintenance, in particular to an outdoor cabinet anti-condensation device and a control method thereof. Background technique [0002] The terminal box is an important equipment in the substation, which plays the role of power, control, measurement and protection. The terminal box is of great significance to improve the insulation and electrical performance of the secondary circuit, prevent various defects and abnormalities caused by the insulation and aging of the secondary circuit, and ensure the safe operation of the main equipment and its system. However, people usually regard the terminal box as a simple container and seldom pay enough attention to it. In places where the temperature difference between day and night is large and the air is humid, the moisture in the air will usually condense into small water droplets when it is cold. After the outdoor terminal box is exposed to the sun du...
