Condensation detection and monitoring device for switch cabinet

Abstract

The invention discloses a condensation detection and monitoring device for a switch cabinet. The device comprises a data acquisition terminal and a data monitoring terminal connected with the data acquisition terminal, wherein the data acquisition terminal comprises a data acquisition module, a multiplex switch, a rectification voltage stabilization module, an analog-to-digital conversion module,a controller module and a wireless sending module which are sequentially connected, and the rectification voltage stabilization module comprises an MPU processing unit, a silicon controlled rectifierrectification unit, a pulse triggering control unit, a pulse triggering unit, a temperature feedback unit and a voltage current variable feedback unit. The device is advantaged in that the circuit structure is simple, the device quantity is small, components satisfy high temperature operation environment requirements, the volume is compact, integral heat radiation amount is relatively small, and the device is suitable for being mounted in the narrow, long and enclosed internal space of underground equipment. Wide voltage and wide frequency signals can be adjusted, limited and protected in thehigh temperature environment.

Description

technical field [0001] The invention belongs to the field of intelligent detection, in particular to a condensation detection and monitoring device for a switch cabinet. Background technique [0002] For information about my country, please visit: Power Transmission and Distribution Equipment Network has used automatic heating and dehumidification controllers to prevent condensation in switch cabinets for more than ten years. Positive effect, but some problems also appeared in the application in some areas, for example: in the rainy season in the south, sometimes the air humidity inside the switch cabinet is high, and there is even condensation in the switch cabinet. The position of the internal condensation sensor has not reached the level of condensation, or the condensation sensor has been eroded by dust and gas in the air for a long time, which affects the sensitivity of the sensor, and the condensation controller cannot start the heater in time. As a result, the condensa...
