Method and device for detecting and processing firing phenomenon of power line

Abstract

The invention relates to a method and a device for detecting and processing firing phenomenon of a power line. The method comprises the following steps of detection: measuring the variation of the current of the power line or the variation of the voltage on the rear end of the power line by utilizing a sensing device; judgment: inputting the measurement values into a processor, processing the variation quantity of the current or the voltage of the power line through a microprocessor and the logic algorithm, judging whether the variation of the current or the voltage is caused by the firing or not; execution: immediately transmitting a control signal through the microprocessor if the firing phenomenon exists, controlling an execution element through a wire or in a wireless way to cut off the power line, and/or transmitting a signal for alarming the firing of the circuit; and continuing to run the power line if no firing phenomenon exists. Due to the adoption of the method and the device, the firing phenomenon can be detected in time before or at the moment when the firing occurs on the power line, the power supply of the circuit can be effectively cut off, and the fire accident caused by the firing of the power line can be prevented.

Description

technical field [0001] The invention relates to a detection and processing method and device for sparking with electric lines. Background technique [0002] Fires caused by aging or overloading of lines and short-circuit phenomenon occur from time to time. According to the statistics of the fire department, fires caused by aging or overloading of lines account for 15-20% of the total fire volume, causing major personnel or property damage. loss. People have always wanted to find a solution to effectively detect or avoid the occurrence of a fire when the line is aging or overloaded and the current or voltage changes, but the fire has not yet formed. There is no effective solution. Contents of the invention [0003] In order to overcome the above problems, the present invention provides the society with a method for detecting and processing electric circuit ignition that can effectively and quickly identify the circuit ignition phenomenon and cut off the power supply in tim...
