Description
Patented July 7, 1931 UNITED STATES PATENT GFFICE REINHOLD RUDENBERG, OF BERLIN-GRUNEWALD, GERMANY, ASSIGNOR TO WESTING- HOUSE ELECTRIC & MANUFACTUIi-ITG COMPANY, 03? NEW' YORK, N. Y., A CORPORA- TION OF AMERICA CIRCUIT BREAKER No Drawing. Application filed. September 8, 19537, Serial No. 218,372, and in Germany September 10, 1926.
My invention relates to circuit breakers.
For breaking electric circuits, more particularly alternating current circuits, the con tact members of the circuit breakers are submerged under oil or any other suitable liquid, because a large volume of heat is then withdrawn from the final arc, whereby the arc is extinguished more easily. In the case where circuits of high power are to be disconnected, the arcs may become very extensive and develop in all directions through the conducting gases formed by the decomposition of the oil.
My invention relates to a circuit breaker in which the arc is confined to a very small. space and the breaking of the circuit involves no danger even when circuits carrying large amounts of power are disconnected.
My invention consists substantially in adding deionizing substances to the medium surrounding the breaker contacts. These quickly bind the current-conducting ions and electrons, which are developed in the arc and at the electrodes and thus extinguish the arc.
According to my invention the elements of the halogen series, such as chlorine, bromine and iodine, are preferably employed. In the case of oil circuit breakers iodine is preferably added as deionizing substance. It is, however, also possible to use, for instance, phosphorous or analogous substances for deionizing the arc.
The substances specified above may be employed in the pure state or in combination with other substances.
In the case of breakers in which the arc is extinguished in a liquid such deionizing substances are preferably chosen which dissolve in the liquid or become finely distributed in it. In air or gas circuit breakers substances are employed which likewise become finely distributed. By a suitable choice of the quantity of the substance, the arcs may either be extinguished immediately on being developed or gradually afterwards.
It is a particularly desirable feature that with the increase of the length of the arc and the decomposition of the breaker medium, for instance the oil, a larger quantity of the dissolved deionizing substances is set free and brings about the blowing out of the arc. Due to the aid of the ion-binding substances in the gaseous state. it is also possible to interrupt circuits having considerable capacity in air. substances are present in sufficient quantity at the point where the arc develops. The air circuit breaker is preferably housed within a closed casing or chamber.
lVhen the word deionizin is emvlo ed in t! l the specification and claims it is to be understood that I have reference to any gas that, when intermingled with the gas in an arc path, will cause the ions thereof to recombine to thereby render the arc path impervious to current flow.
Various changes in the substances employed and in the way of applying them may be made without departing from the spirit of my invention, and I desire therefore, that only such limitations shall be placed thereon as are imposed by the prior art.
I claim as my invention:
1. In combination, a circuit breaker and iodine mixed with the medium surrounding the contact members of said breaker.
2. In combination, a circuit breaker oil surrounding the contact members, and iodine mixed with said oil.
3. In combination, a circuit breaker and. an element of the halogen series in the free state mixed with the medium surrounding the contacts of said breaker.
l. In combination, a circuit breaker and a substance which evolves an element of the halogen series in the gaseous state under the influence of an are mixed with the medium surrounding the contacts of said breaker.
5. In combination, a circuit breaker, oil surrounding the contact members of said breaker. and an element of the halogen series in the free state mixed with said oil.
6. In combination, a circuit breaker, oil surrounding the contact members of said breaker, a substance which evolves an element of the halogen series in the gaseous state under the influence of an are mixed with said oil.
In testimony whereof I aflix my signature.
REINHQLD RUDENBERG.
