Abstract
The utility model relates to a double-breakpoint circuit breaker arc extinguishing device, which comprises an arc extinguishing cover, a grid and an arc extinguishing grid plate. The arc extinguishing grid plate is arranged inside the arc extinguishing cover. The grid is arranged at an arc extinguishing port of the arc extinguishing cover. The integral double-breakpoint circuit breaker arc extinguishing device is modularized and is convenient to store, transport and install when being used as an independent part to assemble; and moreover, the arc extinguishing capacity is strong, the leaked arc is weakened, and the damage of the voltaic arc on the external components can be reduced.
Description
Technical field: the utility model relates to a kind of arc quenching system, especially a kind of arc quenching system that is applied on the dual-interruption point breaker.
Background technology: the present arc quenching system of using, have only with the grid sheet electric arc is introduced arc control device, the electric arc in the arc control device is not drawn arc control device, can produce the electric arc that leaks, bring unsafe factor, the exterior part of also may burning.
The utility model content: at above-mentioned the deficiencies in the prior art, the utility model provide a kind of arc extinguishing ability strong be applied in arc quenching system on the dual-interruption point breaker.
For achieving the above object, the technical solution adopted in the utility model is: the dual-interruption point breaker arc-control device comprises arc-extinguish chamber, grid and arc extinguishing grid pieces.Arc extinguishing grid pieces is in the arc-extinguish chamber.Grid is in the arc extinguishing mouth place of arc-extinguish chamber.
The utility model integral body is modularization, as independent parts assembling, and storage, transportation, easy for installation, and also the arc extinguishing ability is strong, and the electric arc that leaks weakens, and can reduce the damage of electric arc to exterior part.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an internal view of the present utility model
Fig. 3 is a fundamental diagram of the present utility model.
Embodiment:
As depicted in figs. 1 and 2: the dual-interruption point breaker arc-control device, arc extinguishing grid pieces 3 is inserted in the arc-extinguish chamber 2, be set in the arc spraying mouth place of arc-extinguish chamber 2 with grid 1.
Operation principle:
As Fig. 3, as electric arc I1 during in arc extinguishing grid pieces 3 motion, grid 1 has the characteristic of absorption electric arc, make the electric arc I1 of 3 of arc extinguishing grid pieces be adsorbed onto the arc spraying mouth place of arc-extinguish chamber 2 fast, obtain cooling as electric arc I2 and electric arc I4 and be beneficial to arc extinction, because the existence of steel magnetic conduction grid is arranged, make metallic vapour in electric arc I2 and the electric arc I4 absorption electric arc, after electric arc I3 goes out along arc spraying mouth, metallic vapour will reduce to some extent.The existence of grid 1 also helps passing through rapidly of electric arc I1.Grid 1 adopts the metal magnetic conducting material.
Claims (2)
1. the dual-interruption point breaker arc-control device comprises arc-extinguish chamber, and arc extinguishing grid pieces, and arc extinguishing grid pieces is in the arc-extinguish chamber, it is characterized in that: also comprise the grid that is in arc-extinguish chamber arc extinguishing mouth place.
2. dual-interruption point breaker arc-control device as claimed in claim 1 is characterized in that: grid adopts the metal magnetic conducting material.
