Abstract
The invention discloses a kind of arc-extinguishing chamber of circuit breaker sealing installation structure, it includes breaker body, several spark chambers are arranged at intervals with the breaker body, arc-chutes are installed in the spark chamber, arc extinguishing grid pieces are installed in the arc-chutes, wherein, the periphery of the spark chamber is provided with plane indent on the breaker body, elastic caoutchouc packing ring is provided between the arc-chutes and the plane indent, the arc-chutes are sealedly attached on the breaker body by elastic caoutchouc packing ring.The arc-chutes of above-mentioned arc-extinguishing chamber of circuit breaker sealing installation structure are seal-installed on breaker body, breaker is in disjunction high current, when being separated due to contact, arcing contact pulls open elongated electric arc, because the air-tightness of arc-chutes is very high, and only one outlet leads to circuit breaker external, what electric arc can then be concentrated is promptly transferred into arc extinguishing grid pieces segmentation, cooling until extinguishing, raising breaker disjunction index.
Description
Technical field
The present invention relates to a kind of breaker, more particularly, to a kind of arc-extinguishing chamber of circuit breaker sealing installation structure.
Background technology
Breaker is the electric current for referring to close, carry and cut-off under normal loop condition and can closed, when defined
Interior carrying and the switching device for cut-offfing the electric current under abnormal loop condition.It can be used to distribute electric energy, infrequently start different
Motor is walked, power circuit and motor etc. are carried out and protected, when they occur serious overloads or short-circuit and under-voltage wait event
Energy automatic shutdown circuit during barrier, its function is equivalent to Fuse switch and the combination for crossing underheat relay etc..And in disjunction
Parts need not be changed as fault current is latter.At present, obtained a wide range of applications.
Arc-chutes are one of important composition parts of breaker, determine the height of breaker breaking capacity.It is existing disconnected
The arc-chutes of road device are directly assembled in the spark chamber on breaker body, and there is installation arc-chutes both sides with breaker body both sides
Gap so that spark chamber internal pressure leakage, influences breaker breaking speed.
The content of the invention
It is an object of the invention to provide a kind of arc-extinguishing chamber of circuit breaker sealing installation structure, it has good airproof performance and raising
The characteristics of breaker breaking speed, to solve the above mentioned problem that arc-extinguishing chamber of circuit breaker mounting structure is present in the prior art.
For up to this purpose, the present invention uses following technical scheme：
A kind of arc-extinguishing chamber of circuit breaker sealing installation structure, it, which includes being spaced on breaker body, the breaker body, sets
It is equipped with several spark chambers, the spark chamber and arc-chutes is installed, arc extinguishing grid pieces is installed in the arc-chutes, wherein, institute
State on breaker body and the periphery of the spark chamber is provided with plane indent, set between the arc-chutes and the plane indent
Elastic caoutchouc packing ring is equipped with, the arc-chutes are sealedly attached on the breaker body by elastic caoutchouc packing ring.
Especially, the arc-chutes are close with coordinating the elastic caoutchouc packing ring to offer on the fitting surface of the plane indent
Seal groove.
Especially, the section of the elastic caoutchouc packing ring is circular or square any.
Especially, the section of the sealed groove is semicircle or square any.
Beneficial effects of the present invention are, compared with prior art the arc-chutes of the arc-extinguishing chamber of circuit breaker sealing installation structure
It is seal-installed on breaker body, breaker is in disjunction high current, when being separated due to contact, and arcing contact pulls open elongated electricity
Arc, produces the ionized gas of HTHP, promotes breaker arc extinguishing chamber internal pressure to rise.Under HTHP effect, if going out
The air-tightness of arc chamber is very high, and only one outlet leads to circuit breaker external, and what electric arc can then be concentrated is promptly transferred into
Arc extinguishing grid pieces segmentation, cooling are until extinguish, raising breaker disjunction index.

Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1 to Fig. 3, in the present embodiment, a kind of arc-extinguishing chamber of circuit breaker sealing installation structure includes breaker
It is arranged at intervals with body 1, the breaker body 1 in several spark chambers 2, the spark chamber 2 and arc-chutes 3, institute is installed
State and arc extinguishing grid pieces 4 are installed in arc-chutes 3, the periphery of the spark chamber 2 is provided with plane indent on the breaker body 1
5, the arc-chutes 3 have been provided with being offered on the fitting surface of the plane indent 5 in sealed groove 6, the sealed groove 6
The elastic caoutchouc packing ring 7 of sealing function.
The section of the elastic caoutchouc packing ring 7 to be circular or square, the section of the correspondence sealed groove 6 to be semicircle or
It is square.
During assembling, arc-chutes 3 are fitted into breaker body 1, elastic caoutchouc packing ring 7 by the sealed groove 6 of arc-chutes 3 tightly
Push down, tightly pushed down with 5 two faces of plane indent of breaker body 1, be closed body spark chamber, electric arc is direct rapidly
Gone out by the arc extinguishing grid pieces 4 of arc-chutes.
Above example is the general principle and characteristic for elaborating the present invention, and the present invention is not limited by above-mentioned example,
Without departing from the spirit and scope, the present invention also has various change and change, and these changes and modifications are both fallen within
In scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
