Abstract
A sulfur hexafluoride generator breaker is provided with a set of transmission linkage mechanism on a frame. One end of the transmission linkage mechanism is connected with the breaker body with a piston of the operating cylinder of the hydraulic operating mechanism, and the other end is connected with a transmission rod or a rotating shaft of the breaker body to drive the insulation rods of three arc quenching monopoles respectively. The utility model adopts 'single-pressure variable distance axial bidirectional air blast' to quench arc with simple structure and strong breaking capacity for reliably breaking the rated short circuit current. The utility model has good and stable breaking capability especially in breaking of small current. The hydraulic operating mechanism drives three arc quenching monopoles of the breaker to realize mechanical linkage by the transmission linkage on the breaker frame, and the three poles have good synchronization and adjustability. The transmission linkage has simple structure, high mechanical reliability, long service life and suitability for frequent operation.
Description
Technical field
The utility model relates to the high-current switch equipment technical field, particularly a kind of sulphur hexafluoride generator circuit breaker.
Background technology
The sulphur hexafluoride generator circuit breaker is that maximum operating voltage is the indoor high-current switch equipment that the operation-current of 18kV and 24kV is respectively 63KA and the mechanical linkage of 80KA three-phase; the sulphur hexafluoride generator circuit breaker is divided into I according to the mounting means of three arc extinguishing one poles; two kinds of versions of II; three arc extinguishing one poles flatly are installed in and are the I type on the supporting insulator of support; form the circuit breaker of so-called " horizontal type structure "; three arc extinguishing one poles are vertically mounted on respectively and are the II type on the support supporting insulator; be referred to as the circuit breaker of " vertical structure "; the arc extinguishing one pole of I type respectively in addition outer cover can link with isolated-phase enclosed bus easily; be referred to as III type circuit breaker; the corresponding hydraulic actuating mechanism of this sulphur hexafluoride generator circuit breaker adapted; be applicable in the generator loop of cellular construction and expansion unit connection mode; control and protection generating set; also be applicable to other big current circuit; as the control and the protection of transferring the group machine, the sulphur hexafluoride generator circuit breaker that uses mainly exists the shortcoming of the poor stability of connecting-disconnecting function at present.
Summary of the invention
The purpose of this utility model provides a kind of demand that satisfies 300,000 kilowatts, 200,000 kilowatts and following generating set, and connecting-disconnecting function is stablized good sulphur hexafluoride generator circuit breaker.
The utility model is to realize like this, it comprises breaker body, hydraulic actuating mechanism and control cabinet, it is characterized in that breaker body, hydraulic actuating mechanism are fixed on the chassis and form an integral body, support is provided with a cover kinematic link mechanism, breaker body links by the piston on kinematic link mechanism one end and the hydraulic actuating mechanism working cylinder, the other end links to each other with the drive link or the rotating shaft of breaker body, drives the insulating bar of three arc extinguishing one poles respectively.
The utility model adopts " single press to become open apart from axial two-way air-blowing " arc extinguishing, and simple in structure, connecting-disconnecting function is strong, can cut-off rated short circuit drop-out current reliably, especially aspect the cut-offfing of little electric current, has more good and stable connecting-disconnecting function; Hydraulic actuating mechanism is realized mechanical linkage by three the arc extinguishing one poles of kinematic link actuating circuit breaker that are contained on the circuit breaker support, and the synchronism of three utmost points is good, also is easy to adjust; Because kinematic link simple in structure, and Mechanical Reliability height, life-span are long, are suitable for frequent operation.
