Description
Technical field
The utility model relates to electric fire monitoring devices, belong to technical field of fire control.
Background technique
Electrical fire generally refers to release due to electric wiring, electrical equipment, utensil and power supplying and distributing equipment failure
The thermal energy put: the energy discharged such as high temperature, electric arc, electric spark and non-faulting: such as the hot surface of electric heating appliance, having
Ignite ontology or other combustibles under standby burning condition and caused by fire, also include the fire as caused by thunder and lightning and electrostatic.
One, leakage fire
So-called electric leakage is exactly some place of route because of certain reason (natural cause or artificial origin, such as wind rain
Beat, humidity, high temperature, bruising, scratch, rub, corroding) make the insulation of electric wire or the insulating capacity decline of timbering material, cause
Between electric wire and electric wire between (passing through the insulation of damage, bracket etc.), conducting wire and the earth (electric wire by the reinforcing bar of cement wall,
Black sheet iron etc.) some electric current passes through, and this phenomenon is exactly to leak electricity.
When leak electricity occur when, the electric current sewed is flowing into the earth on the way, when position as biggish such as resistance, can generate part
High temperature causes neighbouring combustible to catch fire, so as to cause fire.In addition, equally can also draw in the electric leakage spark that leakage point of electricity generates
Play fire.
Two, short circuit and fire hazard
Bare conductor in electric wiring or after the insulation breakdown of insulated conductor, firewire and adjacent line or firewire and ground wire (packet
Include ground connection and be subordinated to the earth) short circuit is just cried the phenomenon that certain point is touched together, electric current is caused to increase significantly suddenly, it is commonly called as touching
Line, swinging cross or even electric.
Resistance is reduced suddenly when due to short circuit, and electric current increases suddenly, and the calorific value of moment is also very big, greatly exceeds line
Calorific value when road works normally, and strong spark and electric arc are also easy to produce in short dot, insulating layer can not only be made to burn rapidly,
And metal molten can be made, cause neighbouring inflammable combustible combustion, causes fire.
Three, overload fire
So-called overload refers to that when being more than safe carrying capacity by the magnitude of current in conducting wire, the temperature of conducting wire constantly rises
Height, this phenomenon are just named conducting wire overload.
When conducting wire overload, wire insulation aged deterioration is accelerated.When serious overload, the temperature of conducting wire can not
It is disconnected to increase, or even the insulation of conducting wire can be caused to burn, and the combustible near energy ignition leads, to cause fire.
Four, contact resistance crosses conflagration
It is known that: the place of all conducting wires and the connections such as conducting wire, conducting wire and switch, fuse, instrument, electrical equipment is all
There is connector, the resistance formed on the contact surface of connector is known as contact resistance.It can generate heat when there is electric current to pass through connector, this is just
Often occur as.If connector processing is good, contact resistance is little, then the fever of tap points can keep normal temperature with regard to seldom.Such as
There is impurity in fruit connector, be not connected firmly and lean on or other reasons keep junction contacts bad, cause the local electrical resistance of contact site excessive,
When electric current passes through connector, a large amount of heat will be generated here, form high temperature, this phenomenon is exactly that contact resistance is excessive.
On the electric wiring for thering is larger current to pass through, if somewhere there is contact resistance excessive this phenomenon, just
Great heat can be generated in the excessive subrange of contact resistance, melt metal discoloration even, cause the insulation of conducting wire
Layer burns, and dust, the fiber etc. that product is fallen on ignite combustible or conducting wire near burning, to cause fire.
It is electrically still the main original for causing fire according to the Fire Department of Ministry of Public Security's national fire condition analysis report in 2015
Cause.In terms of the fire to have ascertained the reason, 10.5 ten thousand fire are electrically to install and use regulation due to violation to cause, Zhan Quannian
The 30.2% of sum is especially since electrical cause causes compared with having 55.9% in conflagration, and 2 fire disasters and 1 are especially
Fire disaster is caused by electrical cause.The long-range monitoring to electrical fire is realized using technology of Internet of things, and it is anti-to reinforce electrical fire
Keyholed back plate reason and current check are prevention and the important means and method for reducing electrical fire.
