Front of cka10-40l fault arc breaking detector: with the development of national economy, the power consumption of production and residents is increasing, and the occurrence of electrical fire accidents is also increasing
How to effectively detect the causes of electrical fire and reduce the incidence of electrical fire accidents and the loss of life and property has become the research focus of safe power consumption
In the low-voltage distribution system of buildings, the existing protection devices for preventing electrical fire mainly detect the overcurrent caused by overload and short circuit and the residual current caused by grounding fault
When the series fault arc that is easy to cause electrical fire occurs, because the fault current value is lower than the action threshold of traditional protection devices, it can not comprehensively and effectively prevent electrical fire
As a result, the fire caused by electrical fault in China ranks first among the fires caused by other reasons every year
The development status of fault arc detection technology is analyzed, and the key problems to be solved in fault arc detection are analyzed
Secondly, in order to analyze the characteristics of fault arc, an experimental platform for simulating fault arc in low-voltage distribution line is built
The current transformer is used to collect the fault arc current waveform during loop load transformation, and simulate the fault arc under resistive load, inductive load and resistive inductive load respectively
Through a large number of fault arc experiments, the typical characteristics of fault arc can be extracted
Then the wavelet analysis theory is applied to the diagnosis of fault arc
Thirdly, the system uses wavelet analysis as a tool to judge whether fault arc occurs by detecting whether there are periodic singularity points in the current signal
The system selects and constructs the orthogonal quadratic spline wavelet as the wavelet function and uses the wavelet approximation method to carry out the current signal
