Abstract
The utility model relates to a novel isolating circuit breaker. The novel isolating circuit breaker is mainly characterized in that the novel isolating circuit breaker comprises an arc extinguish chamber, and two operating mechanisms, two insulated push-pull rods, two wiring boards, two moving contact contacting parts and two circuit breaker moving contacts symmetrically arranged, wherein the operating mechanisms, the insulated push-pull rods and the wiring boards are disposed outside the arc extinguish chamber, the moving contact contacting parts and the circuit breaker moving contacts are disposed inside the arc extinguish chamber, each operating mechanism, each insulated push-pull rod, each moving contact contacting part and each circuit breaker moving contact are connected in sequence, positions of the circuit breaker moving contacts are controlled by the operating mechanisms through the insulated push-pull rods, and the moving contact contacting parts are connected with the wiring boards. The novel isolating circuit breaker has the advantages that an isolation function is added to the arc extinguish chamber, and therefore the circuit breaker and an isolating switch are integrated to fulfill all original functions of the circuit breaker and meet the requirement of an isolation function, thereby simplifying substation design, largely reducing investment cost, saving equipment floor space, and improving performance reliability.
Description
Technical field
The utility model belongs to breaker technical field, especially a kind of novel isolation circuit breakers.
Background technology
It is to cut off and the connection load circuit that circuit breaker mainly acts on, and the disengagement failure circuit, and the accident that prevents enlarges, thus safety, the stable operation of the equipment of assurance.Isolating switch does not have special arc-control device, can not be used for connecting, cut off load current and short circuit current, can only under the situation that electric wiring cuts off, just can operate, it mainly acts on is insulating power supply, and making has a tangible cut-off point between power supply and the power failure electric equipment.At present in actual applications, circuit breaker and isolating switch design separately as two equipment, so the cost height, and it is big to take up room, complex structure, and equipment easily breaks down.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the novel isolation circuit breakers of a kind of compact conformation, with low cost and stable performance is provided.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of novel isolation circuit breakers, comprise two operating mechanisms that arc control device and symmetry are installed, two insulation pull bars, two terminal blocks, two moving contact contact components and two moving contact of breaker, operating mechanism, the insulation pull bar, terminal block is arranged on the outside of arc control device, the moving contact contact component, moving contact of breaker is arranged on the inside of arc control device, operating mechanism, the insulation pull bar, moving contact contact component and moving contact of breaker are connected successively, operating mechanism is by the position of insulation pull bar control moving contact of breaker, and this moving contact contact component is connected with terminal block.
And the position of described moving contact of breaker comprises separating brake position, closing position and isolated location.
And described arc control device are by vacuumizing or realizing insulation function by injecting SF6 gas.
Advantage of the present utility model and good effect are:
The utility model increases isolation features in the arc control device of circuit breaker, thereby circuit breaker and isolating switch are organically integrated, not only satisfied the original repertoire of circuit breaker, and can also satisfy requirement to isolation features, make the design of transformer station simplify more, investment cost significantly reduces, and instrument and equipment takes up an area of still less, more reliable performance.

Fig. 3 is isolation structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of novel isolation circuit breakers as shown in Figure 1, comprises two operating mechanisms 1, two insulation pull bars 2, two terminal blocks 3, two moving contact contact components 4 and two moving contact of breaker 5 that arc control device 6 and symmetry are installed.Arc control device inside is by vacuumizing or realizing insulation function by injecting SF6 gas; Operating mechanism, insulation pull bar, terminal block are arranged on the outside of arc control device, moving contact contact component, moving contact of breaker are arranged on the inside of arc control device, operating mechanism is installed together with insulation pull bar one end, the other end of this insulation pull bar enters in the arc control device and by the moving contact contact component and is connected with moving contact of breaker, the user can control the position of moving contact of breaker by operating mechanism, this moving contact contact component is connected with terminal block, can realize the closure function of electric loop when switch closes a floodgate.The moving contact position of this novel isolation circuit breakers comprises the separating brake position, closing position and isolated location, when circuit breaker is positioned at the separating brake position, leave certain distance between two moving contact of breaker, as shown in Figure 1, after being subjected to electricity, closing coil can realize closing operation, moving contact is in closing position, as shown in Figure 2, when using operating mechanism control insulation pull bar that two moving contacts of circuit breaker are drawn back certain distance round about from the separating brake position, the moving contact position is in the isolated location, as shown in Figure 3, this moment, circuit breaker can't carry out closing operation, if circuit breaker need carry out closing operation, moving contact of breaker must be pushed back to the separating brake position, just can realize normal closing operation function.
It is emphasized that; embodiment described in the utility model is illustrative; rather than it is determinate; therefore the utility model is not limited to the embodiment described in the embodiment; every by those skilled in the art according to other execution modes that the technical solution of the utility model draws, belong to the scope of the utility model protection equally.
