Abstract
The invention discloses an efficient circuit breaker, which comprises a shell, contacts and metal sheets, wherein the metal sheets are fixedly arranged in the shell; the contacts are arranged on the metal sheet. According to the circuit breaker, the metal sheets are heated to be bent so that the contacts are opened, and a circuit is cut off; after the circuit is cut off, the metal sheets are gradually cooled and straightened due to no current conveyance, the contacts are closed again, and the circuit is closed. The circuit breaker is simple in structure, low in cost and stable and reliable in work.
Description
Technical field
The present invention relates to a kind of efficient circuit breaker.
Background technology
When circuit breaks down or is abnormal, being accompanied by electric current constantly raises, and the electric current raise likely can damage some important devices or the valuable device in circuit, also likely burns circuit and even causes fire, so can cause the massive losses of life and property.Breaker structure complexity on market, cost is high, when fault has occurred circuit, after circuit breaker cuts off circuit, in the maintenance process needed at circuit, if circuit breaker switches on power automatically, will have sizable potential safety hazard.
Summary of the invention
Goal of the invention: the objective of the invention is, in order to solve the deficiencies in the prior art, provides a kind of simple in structure, and cost is low, the reliable circuit breaker of working stability.
Technical scheme: in order to realize above purpose, a kind of efficient circuit breaker of the present invention, it comprises housing, contact and sheet metal, described sheet metal is fixedly arranged in housing, and sheet metal is provided with contact.
Described sheet metal is one group.
Beneficial effect: a kind of high-reliability adjustable current circuit breaker provided by the invention, make to get an electric shock by the sheet metal heated bending and open, circuit is cut off, after circuit disconnects, sheet metal by cooling stretching gradually, goes out a little closure again because of no current, connect again circuit, this breaker structure is simple, and cost is low, and working stability is reliable.
The accompanying drawing explanation
Structural representation when Fig. 1 is on-state of the present invention;
Structural representation when Fig. 2 is off-state of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
Be illustrated in figure 1 a kind of efficient circuit breaker of the present invention, it comprises housing 1, contact 2 and sheet metal 3, and described sheet metal 3 is fixedly arranged in housing 1, and sheet metal 3 is provided with contact 2.
When the electric current in protected circuit surpasses setting; one group of sheet metal 3 is heated and contact 2 is opened; circuit is cut off, after down circuitry, bimetal leaf because of no current by cooling stretching gradually; contact 2 is closed again; connect again circuit, if the excessive reason of line current also get rid of, when the self-recovering type circuit breaker will make circuit and connect; the time and cut off the power supply, played the effect of circuit overload protection with the electric current of restricted passage circuit.
Above-mentioned embodiment is only explanation technical conceive of the present invention and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present invention enforcement according to this, can not limit the scope of the invention with this.All equivalents that Spirit Essence has been done according to the present invention or modification, within all should being encompassed in protection scope of the present invention.
