Embodiment Construction

[0020] The present invention is described in further detail by the following examples.

[0021] see figure 1 As shown, an intelligent power distribution safety control system consists of a group of temperature sensors 1, temperature acquisition unit 2, CANBUS bus 3, RS485 bus 4, input storage 5, comparator 6, data processor 7, LCD touch screen 8, and Text display processing unit 9, central processing unit 10, communication processor 11, Ethernet 12, short message unit 13, control output unit 14, tripping controller 15, and air circuit breaker 16. A group of temperature sensors 1 are arranged near the wiring metal contacts of each main circuit air circuit breaker 16 and its sub-circuit air circuit breakers 16 to obtain temperature signals, and the temperature acquisition unit 2 collects these temperature signals. Since this system can detect at most Monitor the air circuit breakers of five power distribution cabinets, so multiple temperature acquisition units 2 need to be conn...

Abstract

The invention discloses an intelligent power distribution safety control system, which can give an early warning to inform a switch where a hidden danger of overheating occurs, and completely eliminate fire accidents caused by human negligence, untimely inspection and the like. The system consists of temperature sensor, temperature acquisition unit, input memory, data processor, central processing unit, graphic display processing, touch screen, communication processor, Ethernet, SMS unit, control output unit, tripping controller and air breaker The signal output by the temperature sensor installed at each metal contact of the air circuit breaker in the power distribution cabinet is collected by the temperature acquisition unit and input to the storage, data processor and comparator. The display processing, touch screen, and communication processor are used to display and control various parameters, and send over-temperature alarm information through the Ethernet and SMS unit, and trip and power off the air circuit breaker with over-temperature contacts through the control output unit .

Description

technical field [0001] The invention relates to the technical field of power distribution control of low-voltage power distribution cabinets, in particular to an intelligent power distribution safety control system. Background technique [0002] With the improvement of people's living standards and the rapid development of industry, more and more electricity is consumed and the load is increasing. How to use electricity more safely has become a common concern. For the air circuit breaker switch in the power distribution cabinet, as the service time of the air circuit breaker continues to increase, aging will occur slowly, and overloading will also occur from time to time. These factors will cause the contact resistance of the switch contacts to increase greatly. There are many fire cases caused by poor contact and overheating. How to avoid fires caused by overheating of air circuit breaker switches has also become the focus of attention. In the past, the overheating detect...
