Description
Technical field
The utility model belongs to electronics, electric equipment electricity consumption fire security protection technology field, is specifically related to one and has
Automatically the switching mechanism of tripping function.
Background technology:
Electric arc is insulator by after voltage breakdown, non-conductive become conduction the natural phenomena emitted light and heat, be commonly called as " beating
Arc ".Arc fault has sudden, disguised and randomness.Fault electric arc is potential safety hazard common in electric wiring, fault
Electric arc occurs at circuit defective insulation or loose contact, it is also possible to occur at loosening electric wire connection point and aging or broken
In the circuit damaged and the junction of electric appliance circuits, the generation of fault electric arc easily causes the potential safety hazards such as fire, the life to people
Produce the impact of damaging property of living.
Fault electric arc is generally divided into three kinds, is serial arc, parallel arc and electric arc over the ground respectively.At electric short circuit fire
In, ground-fault arc short circuit causes the dangerous maximum of fire, because electric arc has the biggest impedance and voltage drop, it limits
Fault current, makes over-current protection electrical equipment akinesia or can not action in time cut off the electricity supply, the office of several amperes of electric arcs
Portion's high temperature may be up to 3000 ~ 4000 DEG C, it is sufficient to the neighbouring combustible that ignites is on fire.Common circuit protection device such as leaks electricity guarantor
Protection unit, overload protection arrangement, breaker etc., all cannot be effectively protected fault electric arc.
Fault electric arc breaker (Arc Fault Circuit Interrupters, be called for short AFCI) technology be one up-to-date
Circuit protection technology, Main Function is the fire preventing from being caused by fault electric arc.When there is arc fault, due to current strength
Less, less than the setting value of the power system particularly overcurrent protection that low-voltage distribution field is extensively installed, at distribution line eventually
It is to find electric arc cut off circuit in time that end installs fault electric arc breaker (AFCI), effectively reduces that electric arc is damnous arranges
Execute.But fault electric arc breaker in the market still cannot meet the safeguard protection of available circuit.
And, common rocker switch is only applicable to control small-power, low current electrical equipment, and the protection switch on socket
Can only hand switch Guan Bi.And most switch is all single open circuit, dangerous, in the market the various intelligent remote of demand
Controlling automatic power-off switch, original common combined socket and switch (seesaw socket) is not easy to access relevant control system.
Therefore, in view of problem above, it is necessary to propose a kind of novel switching mechanism with automatic tripping function, work as dress
When electric leakage, short circuit, overload, arcing (beyond range of set value) occurs in the combined socket and switch having this switching mechanism, dropout module can be driven
Dynamic switch mechanism movement so that moving contact departs from static contact, plays the protective effect preventing fault from occurring, it is ensured that energising safety connects
Touch, it is to avoid potential safety hazard occurs.And after socket accesses related Control System, safety the most elegant in appearance.
