Abstract
The utility model relates to a vacuum circuit breaker, and belongs to the technical field of power supply equipment. The vacuum circuit breaker comprises an insulating pull rod arranged in a housing. A lower end of the insulating pull rod is in threaded connection with an upper end of an adjusting rod. A lower end of the adjusting rod is in threaded connection with an upper end of a joint bearing. When the adjusting rod is rotated towards a predetermined positive direction, the insulating pull rod and the joint bearing are away from each other. When the adjusting rod is rotated towards a predetermined opposite direction, the insulating pull rod and the joint bearing are close to each other. With the structure of the utility model, the distance between the insulating pull rod and the joint bearing can be adjusted through rotating the adjusting rod, and the over-travel adjusting is realized easily without disassembling, thereby reducing the workload and improving the work efficiency.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker, is particularly useful for 35kv, belongs to the power supply unit technical field.
Background technology
The 35kV vacuum circuit-breaker comprises circuit breaker operation mechanism, pole or insulating cylinder, insulated tension pole, contact arm, contact arm insulating case and plum blossom moving contact at present, and wherein insulated tension pole is the requisite important accessory of 35kV vacuum circuit-breaker.
Because vacuum circuit-breaker needs the excess of stroke to be adjusted in the corresponding claimed range; This just needs to regulate the relative distance between insulated tension pole and the oscillating bearing, is connected with oscillating bearing and the insulated tension pole of existing vacuum circuit-breaker is general direct, carries out the excess of stroke and regulates often between the regular meeting's generation insulated tension pole and oscillating bearing apart from inappropriate situation; Can only disassemble insulating cylinder or pole this moment; Regulate the distance between insulated tension pole and the oscillating bearing again, workload is big, and efficient is low.
The utility model content
The purpose of the utility model is: the problem to above-mentioned prior art exists, a kind of structure vacuum circuit-breaker is cleverly proposed, and need not dismounting and can implement the excess of stroke and regulate, thereby reduce workload and increase work efficiency.
In order to reach above purpose, the technical scheme of the utility model is following:
A kind of vacuum circuit-breaker comprises the insulated tension pole that is placed in the housing, it is characterized in that, said insulated tension pole lower end is threaded with the adjusting rod upper end, and said adjusting rod lower end is threaded with the oscillating bearing upper end; When the predetermined positive direction of present dynasty is screwed said adjusting rod, said insulated tension pole and oscillating bearing each other away from; Present dynasty is predetermined when screwing said adjusting rod in the other direction, said insulated tension pole and oscillating bearing each other near.
After adopting the utility model structure, only needing the rotation adjusting bar is the spacing of scalable insulated tension pole and oscillating bearing, easily realizes excess of stroke adjusting, need not dismounting, thereby reduces workload and improved operating efficiency.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the a-quadrant enlarged diagram of Fig. 1.
Embodiment
Embodiment
Present embodiment vacuum circuit-breaker basic structure such as Fig. 1 comprise the insulated tension pole 1 that is placed in the housing to shown in Figure 2, and insulated tension pole 1 lower end is threaded with adjusting rod 2 upper ends, and adjusting rod 2 lower ends are threaded with oscillating bearing 4 upper ends.Present dynasty is scheduled to positive direction (clockwise or counterclockwise) when screwing adjusting rod 2, insulated tension pole 1 and oscillating bearing 4 each other away from; Present dynasty's predetermined (opposite with predetermined positive direction) in the other direction is when screwing adjusting rod 2, insulated tension pole 1 and oscillating bearing 4 each other near.
Adjusting rod 2 upper ends have screw rod, the lower end is provided with screw, and insulated tension pole 1 lower end is provided with the screw that matches with adjusting rod 2 upper end screw rods, and oscillating bearing 4 upper ends have the screw rod that matches with adjusting rod 2 lower end screws; The screw thread rotation of adjusting rod 2 upper end screw flights and lower end screw is in the opposite direction.
The screw rod of adjusting rod 2 is circumferentially with locking nut 3-1, spring washer 3-2, reaches packing ring 3-3, and spring washer 3-2 and packing ring 3-3 are between locking nut 3-1 and insulated tension pole 1 lower end.
The screw rod of oscillating bearing 4 is circumferentially with locking nut 4-1, spring washer 4-2, reaches packing ring 4-3, and spring washer 4-2 and packing ring 4-3 are between locking nut 4-1 and adjusting rod 2 lower ends.
After present embodiment assembled, when the excess of stroke was regulated, only needing rotation adjusting bar 2 was the spacing of scalable insulated tension pole 1 and oscillating bearing 4; Need before regulating locking nut 3-1 and 4-1 are unscrewed, after the adjusting locking nut 3-1 and 4-1 tightened and get final product.After adopting present embodiment, can easily realize excess of stroke adjusting, need not dismounting, thereby reduce workload and improved operating efficiency.
Except that the foregoing description, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
