Abstract
An arc extinguishing device of a single-break circuit breaker comprises an arc extinguishing cover, a grating, an arc extinguishing grate plate, a shell and a magnetizing plate. The arc-extinguishing grate plate is located in the arc extinguishing cover. The grating is located at an arc extinguishing opening of the arc extinguishing cover. The magnetizing plate is located at the lower end of the grating and fixed on the outer wall of the arc extinguishing cover via the shell. The arc extinguishing device is integrally module, can be assembled as an independent component, is convenient in storage, transport and installation and high in arc extinguishing ability, weakens leaked arc, and can reduce damage of arc to external parts.
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 single-break circuit 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 single-break circuit breaker.
For achieving the above object, the technical solution adopted in the utility model is: the single-break Arc Distinguishing Device for Circuit Breakers comprises arc-extinguish chamber, grid, arc extinguishing grid pieces, shell and magnetic conduction sheet.Arc extinguishing grid pieces is in the arc-extinguish chamber.Grid is in the arc extinguishing mouth place of arc-extinguish chamber.Magnetic conduction sheet is in the grid lower end, is fixed on by shell on the outer wall 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 a stereogram 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 single-break Arc Distinguishing Device for Circuit Breakers comprises arc-extinguish chamber 1, grid 2, arc extinguishing grid pieces 3, shell 4 and magnetic conduction sheet 5.Arc extinguishing grid pieces 3 is in the arc-extinguish chamber 1.Grid 2 is in the arc extinguishing mouth place of arc-extinguish chamber 1.Magnetic conduction sheet 5 is in grid 2 lower ends, is fixed on by shell 4 on the outer wall of arc-extinguish chamber 1.Grid 2, arc extinguishing grid pieces 3 and magnetic conduction sheet 5 are the metal material of magnetic conduction.
Operation principle:
As shown in Figure 3, as electric arc I1 during in arc extinguishing grid pieces 3 motion, steel magnetic conduction sheet 5 has the characteristic of absorption electric arc, makes the electric arc I1 of 3 of grid arc quenching plates be adsorbed onto the inwall of arc-extinguish chamber 1 fast, and electric arc I2 and electric arc I3 are cooled off and gas that arc-extinguish chamber 1 is given out helps arc extinction.When electric arc I4 when the arc extinguishing mouth sprays because the existence of steel magnetic conduction grid 2 is arranged, the metallic vapour in the absorption electric arc, electric arc I4 prolong arc spraying mouth go out after, metallic vapour will reduce to some extent.The existence of steel magnetic conduction grid 2 also helps passing through rapidly of electric arc I4.
