Abstract
The invention discloses a kind of fault electric arc detector, including signal gathering unit, microprocessor unit, alarm unit and power circuit unit；Signal gathering unit, for gathering the current and voltage signals in electric circuit；Microprocessor unit, is connected with signal gathering unit, for receiving the signal that signal gathering unit is collected, it is judged that whether there is fault electric arc in circuit, and controls alarm unit duty according to judged result；Described microprocessor unit has arc fault detection module.Arc fault electrical fire-detector of the present invention can be by the voltage of lasting supervisory circuit, current waveform, by using testing circuit to distinguish normal and abnormal arc state.Abnormal conditions at the arc once being detected, detector will send alarm signal, reduces the probability of breaking out of fire.
Description
Technical field
The present invention relates to arc detection technical field, particularly relate to a kind of fault electric arc detector.
Background technology
Electric wiring in family can because of short circuit, aging circuit, loose contact, electric equipment products failure and other reasons and
Circuit produces electric arc.Electric arc is a kind of air electric conduction phenomena, produces strong and lasting electric discharge, energy between two electrodes
Concentrating, temperature is high, easily causes the fire incident in family.But arc fault can not be produced by traditional household circuit breaker
Protection, a kind of in prevention family fire accident can be the most necessary for the chopper of arc fault.
Summary of the invention
It is an object of the invention to for defect present in prior art, and a kind of electric energy quality detection device is provided.
For realizing the purpose of the present invention, the invention provides a kind of fault electric arc detector, including signal gathering unit, micro-
Processor unit, alarm unit and power circuit unit；Signal gathering unit, for gathering the current/voltage in electric circuit
Signal；Microprocessor unit, is connected with signal gathering unit, for receiving the signal that signal gathering unit is collected, it is judged that
Whether circuit exists fault electric arc, and controls alarm unit duty according to judged result；Described microprocessor unit has
There is arc fault detection module；Described alarm unit, is connected with microprocessor, during for arc fault occurs in electric circuit
Realize buzzer warning, thus play the effect of early warning；Described power circuit unit, is used for as signal gathering unit, micro-process
Device unit and electrical apparatus release unit provide power supply.
Compared with prior art, beneficial effects of the present invention is, arc fault electrical fire-detector can be by persistently supervising
The control voltage of circuit, current waveform, by using testing circuit to distinguish normal and abnormal arc state.Exception once detected
Conditions at the arc, detector will send alarm signal, reduces the probability of breaking out of fire.
