Abstract
The invention discloses a part of a breaker, and particularly relates to a breaker manipulator. The breaker manipulator comprises a manipulator and a push rod connected with a vacuum arcing chamber moving contact part, wherein the manipulator swings around an installation supporting point; the upper end of the manipulator is provided with a semispherical indentation, the rear end of the push rod passes through a cross-under hole arranged at the center of the semispherical indentation and is a spacing nut, and a compression spring is pressed between the manipulator and a step at the middle part of the push rod; and a wear-resistant block is arranged on the semispherical indentation and matched with the semispherical indentation, the center of the wear-resistant block is provided with a center hole through which the push rod can pass, and rear end of the compression spring is pressed on the front end face of the wear-resistant block. By utilizing the structure, the compression spring iscontacted with the manipulator through the wear-resistant block in a breaker manipulator swinging process so as not to generate friction on the manipulator, the abrasion is effectively reduced, the transferring accuracy is ensured, and the working parameter stabilization of the breaker is improved.
Description
Technical field
The present invention relates to a kind of parts of vacuum circuit-breaker, specifically a kind of breaker manipulator.
Background technology
Vacuum circuit-breaker generally drives the push rod that is connected with moving contact by the motion arm that swings and realizes feed motion, usually is pressed with Compress Spring between motion arm and the push rod, is used for the contact is produced precompression.The contact portion of Compress Spring and motion arm arranges a hemispheric depression usually, and in the motion arm swing process, the root of Compress Spring slides at hemispheric inner surface, to reduce resistance.Although this structure can realize spring held stationary transition in the motion arm swing process, but between spring and the hemisphere inner surface contact and rough, still has larger frictional force, athletic meeting causes the contact portion wearing and tearing of motion arm, the size of bringing and the variation of spring force to vacuum circuit-breaker minute, Circuit Closing Parameters produces a very large impact, and reduced the job stability of circuit breaker.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of can effectively reducing wear, and guarantees the breaker manipulator of transmitting accuracy.
In order to solve the problems of the technologies described above, breaker manipulator of the present invention, include motion arm and be connected push rod with the vacuum interrupter moving contact part, motion arm is installed a spot wobble around it, the motion arm upper end is provided with the depression of hemisphere face shape, putting back-end passes the jack hole that hemisphere face shape Depression Centers arranges, and at putting back-end stop nut is installed, and is pressed with Compress Spring between the step at motion arm and push rod middle part; Be provided with the wear-resistant block that cooperates with it in the depression of described hemisphere face shape, described wear-resistant block center is provided with the centre bore that passes for push rod, and described Compress Spring rear end is pressed on the wear-resistant block front end face.
The rear end of described wear-resistant block is the sphere that matches with the depression of hemisphere face shape.
Be provided with draw-in groove on the front end face of described wear-resistant block, the rear end of described Compress Spring is stuck in the draw-in groove.
Described wear-resistant block is made by high-abrasive material.
After adopting such structure, in the breaker manipulator swing process, Compress Spring contacts with motion arm by wear-resistant block, and not direct and motion arm rubs, and has effectively reduced wearing and tearing; In addition, adopt sphere to cooperate between wear-resistant block and the motion arm, further reduced wearing and tearing, guaranteed transmitting accuracy, improved stablizing of circuit breaker running parameter.
Description of drawings
Fig. 1 is the structural representation of breaker manipulator of the present invention;
Fig. 2 is the wear block structure enlarged drawing of breaker manipulator of the present invention.
Embodiment
As shown in Figure 1, this breaker manipulator includes motion arm 1 and is connected push rod 2 with the vacuum interrupter moving contact part, motion arm is installed a spot wobble around it, motion arm 1 upper end is provided with the depression 3 of hemisphere face shape, putting back-end passes the hemisphere face jack hole 4 that 3 centers arrange that caves in, and in push rod 2 rear ends stop nut is installed, be pressed with Compress Spring 8 between the step at motion arm 1 and push rod 2 middle parts; Be provided with the wear-resistant block 5 that cooperates with it in the depression 3 of hemisphere face shape, the wear-resistant block center is provided with the centre bore that passes for push rod, and Compress Spring 8 rear ends are pressed on the wear-resistant block front end face.As shown in Figure 2, the rear end of wear-resistant block 5 is the hemisphere faces 6 that match with the depression 3 of hemisphere face shape.Be provided with draw-in groove 7 on wear-resisting 5 front end face, the rear end of Compress Spring 8 is stuck in the draw-in groove.Wear-resistant block is made by high-abrasive material.
In the circuit breaker course of work, when motion arm swung, the Compress Spring rear end was by wear-resistant block and motion arm contact and relative friction, and frictional resistance is little, wearing and tearing are little.
