Abstract
The utility model discloses a circuit breaker, which relates to the technical field of circuit breakers, and is characterized by comprising a cabinet body, an isolating-grounding switch, a vacuum arc extinguishing chamber, a circuit breaker operating mechanism and an isolating-grounding switch operating mechanism, wherein the isolating-grounding switch is arranged in the internal of the cabinet body, the vacuum arc extinguishing chamber is connected with the lower part of the isolating-grounding switch, the circuit breaker operating mechanism is connected with the lower side of the isolating-grounding switch, and the isolating-grounding switch operating mechanism is connected with the upper side of the isolating-grounding switch. The circuit breaker is simple and reasonable in structure, convenient to use and easy to operate, has the arc extinguishing and grounding functions, and is high in safety.
Description
Technical field:
The utility model relates to breaker technical field, specifically a kind of circuit breaker.
Background technology:
Circuit breaker (English name: circuit-breaker; circuit breaker) refer to the electric current that can close, carry and cut-off under normal loop condition, and can close, in official hour, carry and cut-off the switching device of the electric current under abnormal loop condition (comprising short circuit condition).Circuit breaker can be used to distribute electric energy; do not start continually asynchronous motor; power circuit and motor etc. are carried out to protection, can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for they, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And after disjunction fault current, generally do not need to change parts.The circuit breaker of prior art, have without vacuum interrupter, and the function of ground connection, so fail safe is lower, or vacuum interrupter and isolation earthing switch arrange unreasonablely, it is not very convenient causing operation.
Utility model content:
Technical problem to be solved in the utility model is to provide breaker cabinet a kind of easy for operation, safe.
The technical problem solving adopts following technical scheme:
A kind of circuit breaker, it is characterized in that: comprise cabinet, isolation earthing switch, vacuum interrupter, breaker operation mechanism and isolation earthing switch operating mechanism, described isolation earthing switch is arranged on the inside of cabinet, described vacuum interrupter is connected with the bottom of isolation earthing switch, described breaker operation mechanism is connected with the downside of isolation earthing switch, and described isolation earthing switch operating mechanism is connected with the upside of isolation earthing switch.
Described isolation earthing switch is air switch.
Described isolation earthing switch operating mechanism is motor mechanism.
The beneficial effects of the utility model are: the utility model is simple and reasonable, easy to use, are convenient to control, and have the function of arc extinguishing and ground connection, safe.
Accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model circuit diagram.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, 2, a kind of circuit breaker, comprise cabinet 1, isolation earthing switch 2, vacuum interrupter 3, breaker operation mechanism 4 and isolation earthing switch operating mechanism 5, isolation earthing switch 2 is arranged on the inside of cabinet 1, vacuum interrupter 3 is connected with the bottom of isolation earthing switch 2, breaker operation mechanism 4 is connected with the downside of isolation earthing switch 2, and isolation earthing switch operating mechanism 5 is connected with the upside of isolation earthing switch 2.Isolation earthing switch 2 is air switch.Isolation earthing switch operating mechanism 5 is motor operated driving mechanism.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
