Description
Technical field
The utility model belongs to arc fault detection technique field, is specifically related to a kind of arc fault detection device.
Background technology
Counted according to the Fire-Fighting Bureau under the Ministry of Public Security, electrical fire 254187 occurs altogether within 2007~2012 years and rise, electric reason causes
Fire account for fire sum 30% and it is throughout the year high, lose accounting about 50%, be the most important thing of fire disasters protection.
Electrical fire 11.3 ten thousand (to ascertain the reason) occurs within 2013,1 electrical fire occurs within average 6 minutes, causes 703 people dead altogether
Die 515 people injury, 48.5 hundred million yuan of direct property loss.
Short circuit, overload, overvoltage, electric leakage and electrical fire caused by thunderbolt, fuse, breaker and residue electricity can be passed through
Stream protector is prevented and protected.But still there are some easily to trigger the electric fault of fire to be not detected, such as connect
Loosening, electric wire aging, loose contact and electric wire breakage etc. is connect to produce fault electric arc and then trigger fire.Here it is why install
Complete protection equipment, also have the basic reason of electrical fire generation.
Because insulation ag(e)ing is damaged, electrical connection loosens, there was dampness in the air, voltage in electric wiring or equipment during fault electric arc
Electric current the reason such as drastically raises and causes the gas ionization caused by air breakdown to discharge scene.Fault electric arc is commonly called as ' electric spark ',
' sparking ' is called, its main harm is to trigger fire.When fault electric arc occurs, can continue to produce more than 3000 DEG C of high temperature,
And come out with metal melt splash, when surrounding has combustible, easily trigger fire.
In existing electic protection technology, main protection device include breaker, residual-current electrical fire detector,
Temp.-measuring type electrical fire-detector, wherein, breaker by the numerical value such as electric current, voltage or Leakage Current in collection circuit and
Given threshold is compared, so as to judge the action of breaker.But when producing serial arc, parallel arc in circuit, circuit
In operating current vary less, and No leakage electric current.Normal circuit breaker can not be protected to fault electric arc；Residual current is visited
Device is surveyed to construct by residual current Detection Techniques specification electric wiring in electric fire monitoring system, it is electric so as to lower the later stage
Circuit runs hidden danger, reduces electrical fire risk.But because of aging circuit, loose contact, damage in insulation etc. when it runs to circuit
Fault electric arc None- identified and protection caused by situation；Temp.-measuring type electrical fire-detector passes through in the pass of circuit or distribution system
Key section mounting temperature sensor monitor the spot temperature change, with given threshold relatively come realize monitoring and forewarning function, but
It can only be detected in mount point, full line can not be protected and monitored.
