Description
Technical field
This utility model relates to Low Voltage Electrical Apparatus, particularly to a kind of motor protection chopper.
Background technology
During the opening and closing of low-voltage electrical apparatus, particularly when the big electric current of disjunction, can produce in air dielectric
Switching arc, lights electric arc and is dependent on the metal vapors of contact during beginning, then ambient air medium is progressively entered
Entering arc gap makes metallic phase arc be changed into the gaseous phase arc supported by gas ionization, and electric arc is a High Temperature High Pressure
Ionized gas, arcing gas destroys the material of contactant consumingly, and therefore, people use grid in recent years
Arc extinguishing, the most as soon as possible by semi-enclosed for arc transfer to rear end independent arc-chutes, relies on grid to produce
The superposition of the proximal pole pressure drop of raw many short arcs improves arc voltage, to suppress increasing of short circuit current；Another
Aspect utilizes high arc temperature to cause pressure to rise in arc-chutes, is formed the air-blowing effect of air-flow by exhaust duct
With by the grid compartmentation to electric arc, it is achieved quickly extinguish electric arc.Traditional motor protection circuit breaker
Arc-chutes are assemblied with base by pedestal, need to reserve static contact due to pedestal and install window and dynamic tactile bridge driving
Window, therefore open wide on arc-chutes rear end and top, the arc stream that disjunction fault current produces, one is
Towards gas outlet, another stock gas outlet dorsad, two strands of air-flows are escaped by above-mentioned two class windows, so that electric
Arc air-flow air pressure reduces, and affects the gas driving velocity to electric arc.
