Utility model content
The utility model provides the knife switch structure that can realize Long-distance Control, solve the neutral point contact isolating switch structure of transformer in the past and cannot realize Long-distance Control, or poor effect, give and patrol and examine increase workload, also bring the problem of certain potential safety hazard simultaneously.
The purpose of this utility model is achieved through the following technical solutions: the knife switch structure that can realize Long-distance Control, comprise supporting seat and be arranged on the first insulator on supporting seat, the second insulator, the first insulator, the top of the second insulator is connected with respectively first and leads rod, second leads rod, the first insulator and first is led excellent junction and is provided with the first insulating case, the second insulator and second is led excellent junction and is provided with the second insulating case, described first leads rod is flexibly connected with the first insulator, first leads rod can lead centered by rod and the tie point of the first insulator and realize and rotating by first, first leads excellent front end is provided with buckle, first leads excellent rear end is connected with stay cord, the far-end of stay cord is provided with motor, stay cord is wrapped on the rotor of motor, described second leads excellent front end is provided with contact, buckle can be buckled on contact completely.First leads rod leads rod and is in fact just similar to plug-in strip with second, realizes the break-make of circuit by switching; The upper end of the first insulator is first to lead the excellent strong point, is also first to lead the axle point that rod rotates, and when motor forward, tightens up stay cord, now first leads one end that rod is provided with buckle and moves upward, and second leads excellent upper contact head and departs from, and circuit disconnects; When motor reversal, stay cord loosens, first leads rod rotates under the effect of self gravitation, first leads one end that rod is provided with buckle moves downward, and with the second contact of leading on rod, realize circuit and connect, thus, by motor is controlled, realize the Long-distance Control to whole knife switch structure.
Further, the center line of the first insulator is positioned on vertical direction, and the center line of the center line of the second insulator and the first insulator intersects.
Further, the angle that the center line of described the first insulator becomes with the center line of the second insulator is 30 ~ 45 degree.
Further, described buckle is shaped as a box body structure that lacks upper surface, a side.Even if the place at contact produces electric arc, this box body structure also can prevent that the fireball that electric arc produces from splashing, and plays certain insulating effect to a certain extent.
Further, described contact is shaped as triangular prism.Triangular prism shaped contact one can contact with buckle better, two be also convenient to buckle and contact contact with separated between switch.
Further, described motor is stepping motor.Stepping motor is easy to control, and can realize the rotation in certain angle, realizes switching over.
The utlity model has following beneficial effect:
(1) the utility model is led rod and second using first and is led rod as knife switch structure, by it, open and close to realize the break-make of circuit, simultaneously, by motor, control first and lead excellent position, with this realize first lead rod lead excellent contact with separated with second, reach the object of Long-distance Control, for patrolling and examining, bring convenience.
(2) the utility model is by design buckle and contact, not only realized good electrically contacting, avoided as much as possible the generation of electric arc, even if buckle can also be in the situation that having produced electric arc simultaneously, electric arc is played to certain insulating effect, the generation avoiding a nasty accident.
