Abstract
The utility model relates to a three-phase linkage mechanism of a tank circuit breaker, characterized by comprising a three-phase linkage, an insulating pull rod, a linkage left side bearing, a linkage right side bearing and a manipulator linkage. The three-phase linkage is integrated and is fixed in a shell via the linkage left side bearing and the linkage right side bearing, the manipulator linkage is connected with three-phase linkage via a pin and drives the three-phase linkage to rotate, and the three-phase linkage is connected with an insulating linkage via a pin and drives the insulating pull rod to do reciprocating motion when rotates. The advantages of the utility model are that the larger phase difference problem caused by meshing department precision and wear is solved, and at the same time, the manufacture cost is reduced, the structure is simple and the use is convenient.
Description
Technical field
The utility model relates to a kind of connecting rod, relates in particular to a kind of potting breaker three-phase linkage.
Background technology
Along with development of social industrialization; Electricity needs is also in continuous growth; Sulfur hexafluoride breaker is also used in high pressure and ehv power transmission system widely; Three-phase connecting rod engagement problem is perplexing each manufacturer always in the three-phase linked circuit breaker, and the three-phase connecting rod in the general three-phase linked circuit breaker is a segmented, meshes with tooth between connecting rod; But the precision problem of making because of flute profile and the wearing and tearing of long period of operation, the differing of three-phase action come bigger seriously the time even tooth can occur and collapse and cause the phenomenon that can't operate approximately.
The utility model content
The purpose of the utility model provides a kind of potting breaker three-phase linkage.
The technical scheme that the utility model adopts is:
Potting breaker three-phase linkage; Said three-phase linkage comprises three-phase connecting rod, insulated tension pole, connecting rod left side bearing, connecting rod right side bearing and operator link-age; Said three-phase connecting rod is an integral type, is fixed in the housing through connecting rod left side bearing and connecting rod right side bearing; Said operator link-age is connected with pin with the three-phase connecting rod, and operator link-age drives the three-phase connecting rod and rotates; Said three-phase connecting rod is connected with pin with insulated connecting rod, drives insulated tension pole when the three-phase connecting rod rotates and moves reciprocatingly.
The utility model has the advantages that: solve engaging piece precision and wearing and tearing and caused the problem that differs bigger, reduced manufacturing cost simultaneously, simple in structure, easy to use.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Fig. 1 is the structural representation of whole set equipment.
Fig. 2 is the structural representation of three-phase connecting rod among Fig. 1.
Fig. 3 is the enlarged drawing of A-A among Fig. 2.
Wherein: 1, three-phase connecting rod, 2, insulated tension pole, 3, housing, 4, connecting rod left side bearing, 5, connecting rod right side bearing, 6, operator link-age, 7, pin.
Embodiment
Shown in Fig. 1-3; The potting breaker three-phase linkage of the utility model; The three-phase linkage comprises three-phase connecting rod 1, insulated tension pole 2, connecting rod left side bearing 4, connecting rod right side bearing 5 and operator link-age 6; Three-phase connecting rod 1 is an integral type, is fixed in the housing 3 with connecting rod right side bearing 5 through connecting rod left side bearing 4; Operator link-age 6 is connected with pin 7 with three-phase connecting rod 1, and operator link-age 6 drives three-phase connecting rod 1 and rotates; Three-phase connecting rod 1 is connected with pin 7 with insulated connecting rod 2, drives insulated tension pole 2 when three-phase connecting rod 1 rotates and moves reciprocatingly, and has solved engaging piece precision and wearing and tearing and has caused the problem that differs bigger, has reduced manufacturing cost simultaneously, and is simple in structure, easy to use.
The operation of the utility model: three-phase connecting rod 1 is fixed in the housing 3 by connecting rod left side bearing 4 and connecting rod right side bearing 5; When operator link-age 6 upwards operates, drive three-phase connecting rod 1 and rotate counterclockwise, the insulated tension pole 2 that three-phase connecting rod 1 promotes three-phase moves together; When operator link-age 6 running downwards, drive three-phase connecting rod 1 and clockwise rotate, the insulated tension pole of three-phase connecting rod 1 pulling three-phase moves together.
