Intelligent temperature controller and intelligent temperature controller system applied to power distribution cabinet temperature monitoring

Abstract

The invention relates to an intelligent temperature controller applied to power distribution cabinet temperature monitoring. The intelligent temperature controller comprises a first master control chip which performs bidirectional communication with a first carrier wave communication module and a metering module used for metering consumption of a heater and an exhaust fan. An output end of the first master control chip is connected with an input end of a relay, and an output end of the relay is connected with control ends of first and second alternating current contactors. One end of the first alternating current contactor is connected with the metering module, and the other end of the first alternating current contactor is connected with the heater. One end of the second alternating current contactor is connected with the metering module, and the other end of the second alternating current contactor is connected with the exhaust fan. The invention can overcome defects that the temperature control range of a temperature controller is required to be manually set and cannot be remotely controlled and adjusted; the metering function is achieved, that whether the threshold of temperature control is reasonable or not can be determined, and remote control is achieved; in addition, the intelligent temperature controller and an intelligent temperature controller system adopt power line carrier communication based on a high speed narrowband protocol, thereby being stable and fast in communication and convenient in networking.

Description

technical field [0001] The invention relates to the technical field of intelligent temperature controller devices, in particular to an intelligent temperature controller and a system thereof for temperature monitoring of a power distribution cabinet. Background technique [0002] As we all know, the higher the humidity of the air, the more water vapor can be contained in the air, and the greater the saturated humidity. If the air humidity is kept constant and the air temperature is lowered, when the temperature is lowered to a certain value, the water vapor in the air will reach saturation. If the air temperature is lowered further, water vapor will condense out of the air, forming dew droplets. In the power distribution cabinet, as the ambient temperature rises, due to the existence of thermal inertia, the surface temperature of the electrical equipment will be lower than the ambient temperature. When the hot and humid ambient air meets the equipment surface below the de...

Problems solved by technology

It can be seen that the traditional thermostat has a single function, requires manual setting of the temperature control range and cannot be adjusted remotely
