Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing: as shown, a kind of pole leakage circuit breakers N arc extinguishing knot
Structure, including shell 1, moving contact 2 and static contact panel 3 are correspondingly provided in the shell, and the shell is equipped with through-hole 11, the stationary contact
Plate is equipped with and first leads arc plate 41, further includes that lead that arc plate is correspondingly arranged with described first second leads arc plate 42, described second leads
Arc plate one end is correspondingly arranged with the through-hole, and the other end is correspondingly arranged at below the moving contact.It is produced on moving contact and static contact panel
When raw electric arc, arc plate and second can be led by first and lead arc plate elongating arc for extinguishing, and be discharged from through-hole, as preferred side
Case, this first is led arc plate and connect with static contact panel, this second is led arc plate and connect with junction block 91.
In the present embodiment, as shown, the static contact panel is equipped with static contact 31, the static contact panel includes the first plate
301 and first the second plate 302 that is formed of plate bending, the static contact back connect with first plate, the static contact bottom
With second plate rear end face contact.Make static contact bottom there is no empty slot, static contact in the prior art is to protrude from stationary contact
Plate, static contact lower end are empty slot, are easy to accumulate at this in this way when leading arc and cause phenomena such as burning, therefore, this Shen
Please in static contact bottom be in contact with the second plate rear end face, there is no accumulation the phenomenon that, it is not easy to burn.
In the present embodiment, as shown, second plate be higher than the static contact or second plate with it is described quiet
Contact is concordant.
In the present embodiment, as shown, described first leads arc plate and second plate welding.
