Abstract
The utility model discloses an arc-extinguisher of a double-line circuit breaker with an earth leakage protective function. The arc-extinguisher comprises a coil and a zero-sequence mutual inductor, wherein the zero-sequence mutual inductor is arranged on one end of the coil, a hollow cavity is formed between a static contact and an arc-striking plate under the coil, and an arc-extinguisher which is matched with the hollow cavity is arranged in the hollow cavity. The arc-extinguisher has the advantages that the surface area of the arc-extinguisher is several times better than that of a traditional arc-extinguisher, and meanwhile, arc extinction is conducted to the N pole. Therefore, the arc-extinguisher has extremely excellent arc-extinguishing effect.
Description
Technical field
The utility model relates to a kind of circuit breaker, particularly a kind of arc-extinguish chamber of circuit breaker.
Background technology
Because the volume of circuit breaker is little, particularly the volume of Subminature multifunctional residual current circuit breaker is littler, has only a modulus, be that width is 18mm, in so little volume, traditional arc-extinguish chamber all is to have only single layer structure, and is thinner, cause the arc-extinguish chamber volume all very little, because the arc quenching effect of arc-extinguish chamber is directly proportional with its volume.The effect of slow, the cold arc of the arc-extinguish chamber of smaller size smaller heat radiation, arc extinguishing is bad.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of arc-extinguish chamber with two-wire circuit breaker of creepage protection function, can reach cold preferably arc and arc quenching effect.
To achieve these goals, technical solution adopted in the utility model is:
A kind of arc-extinguish chamber with two-wire circuit breaker of creepage protection function, comprise coil, zero-sequence transformer, zero-sequence transformer is positioned at an end of coil, form a cavity between fixed contact below the coil and the run-on tab, be provided with the arc-extinguish chamber that cooperates with cavity in the cavity, arc-extinguish chamber is by some grid card plate and be installed on card plate side faces at both ends card plate and constitute, described grid card plate is according to the longitudinal subdivision setting, arc-extinguish chamber is the L shaped shape that L shaped shape of disjunctor or split rectangle are formed, L shaped arc-extinguish chamber is divided on the L pole-face, two parts under the N pole-face, L pole-face volume is greater than N pole-face volume;
The back side of arc-extinguish chamber also is provided with the little arc control device of a sealing, and the arc-extinguish chamber of promising N utmost point arc extinguishing is set in the arc control device.
The beneficial effects of the utility model: the arc-extinguish chamber volume is the several times of traditional arc-extinguish chamber volume, simultaneously, and also to the zero line arc extinguishing; Therefore, the effect arc extinguishing of arc extinguishing of the present utility model is very good.

Embodiment
See also its implementation process of description of drawings:
A kind of arc-extinguish chamber with two-wire circuit breaker of creepage protection function, comprise coil 8, zero-sequence transformer 28, spring 20, zero-sequence transformer 28 is positioned at an end of coil 8, and traditional zero-sequence transformer 28 is positioned at the below of coil 8, makes that the space of arc-extinguish chamber 5 is narrow especially; The utility model is exactly the end position almost parallel with coil 8 that the position of zero-sequence transformer 28 is moved to coil 8.Coil 8 is supported on the coil brace 34, forms a big cavity between the fixed contact 19 below the coil 8 and the run-on tab 22, is provided with the arc-extinguish chamber 5 that cooperates with cavity in the cavity greatly; Arc-extinguish chamber 5 outer volumes are very big, and arc-extinguish chamber 5 is that two arc control device disjunctors that vary in size constitute or separately constitute; The back side of arc control device 5 also is provided with the little arc control device of a sealing, and the arc-extinguish chamber of promising N utmost point arc extinguishing is set in the arc control device.Driving handle 13, under the effect of torsion spring 12, button 11 is used for the test effect.Drive tripping 16, snap close 17, spring 18, connecting rod 25 simultaneously, make fixed contact 19 and moving contact 27 contact, can produce electric arc, electric arc is introduced arc control device 5 by run-on tab 22 in the moment of contact.Also comprise strutting piece 29, axle 30 in addition.
More than be a kind of detailed embodiment of the present utility model, but mentality of designing of the present utility model is not limited thereto, all this thinkings of utilizing do not have substantial change to the utility model, all belong to the behavior of invading the utility model protection range.
