Abstract

The invention discloses an arc fault breaker detection device which comprises a supply voltage detection module, an SCM control module and an arc fault breaker detection module which are connected in sequence, the supply voltage detection module comprises a power supply polarity detection and voltage synchronous detection circuit which is used for transmitting a square signal to the SCM control module, and the arc fault breaker detection module comprises a trigger pulse control circuit which is controlled by the SCM control module and detects the arc fault breaker. The invention also discloses a method for detecting the arc fault breaker detection device, the method avoids catastrophic fire accident caused by function failure caused by arc fault breaker aging, damage or poor technology, and the method also can effectively reduce the probability of the accident and improve the safety.

Description

technical field [0001] The invention relates to the technical field of arc fault interrupter testing, in particular to an arc fault interrupter detection device and a detection method thereof. Background technique [0002] According to fire data statistics, fires caused by electrical causes are the most frequent among various types of fires, and their severity is also in the forefront, while electrical fires are mainly caused by arc faults. Therefore, how to prevent fires caused by arc faults is very important Extra important. [0003] Therefore arc fault interrupters are being added to more and more circuits. The arc fault interrupter is a protective device that disconnects the power circuit before the arc fault develops into a fire or a short circuit occurs by identifying the characteristic signal of the arc fault in the circuit. Sometimes due to the aging of the arc fault interrupter, man-made damage or poor workmanship and other reasons, the function of the arc fault i...
