Design concept of the present invention is: utilize a conversion operation mechanism to make the isolating switch of high-tension switch cabinet and circuit breaker chain each other, avoid the not enough problem of air clearance, when making isolating switch be in closing position, circuit breaker tripping, can not close a floodgate, and stop manual, electronic closing operation; When isolating switch was in the separating brake position, circuit breaker can close a floodgate.
For realizing above goal of the invention, conversion operation mechanism for high-voltage switch cabinet isolation switch of the present invention contains power transmission shaft, actuating arm, pull bar, extension pin, torque arm, rotating shaft, push arm, extension pin, push rod, extension pin, isolating switch connecting lever and support; It is characterized in that, the lower end lock ring of actuating arm is on power transmission shaft, one end pin joint of the other end of actuating arm and pull bar, pull bar is vertical and away from a busbar, and the other end of pull bar is connected with an end of torque arm with hanging pin, and the other end of torque arm is connected with an end of rotating shaft, shaft set is on support, the other end of rotating shaft is being close to push arm, and the other end of push arm is connected with an end of push rod by hanging pin, and the other end of push rod is connected with an end of isolating switch connecting lever by hanging pin; The other end of isolating switch connecting lever connects isolating switch.
Described pull bar is made of the body of rod of centre and two saddle structures at two ends, and the bottom of saddle structure is connected with the female scalable of carrying out of Luo with body of rod two ends (screw shaped).
Described push rod is made of the body of rod of centre and two saddle structures at two ends, and the bottom of saddle structure is connected with the female scalable of carrying out of Luo with body of rod two ends (screw shaped).
The two ends of described pull bar are connected with abutment with hanging pin.
The two ends of described push rod are connected with abutment by hanging pin.
Described torque arm, push arm are the cam-like standard component, and torque arm, push arm are linked to be integral body with different radiuses and angle and rotating shaft.
When the isolating switch sub-switching operation, change on the actuating arm, drive on the pull bar and carry, change in the torque arm, drive push arm through rotating shaft, push rod, isolating switch connecting lever are moved to the separating brake direction of isolating switch, make the isolating switch separating brake.
When the isolating switch closing operation, actuating arm is commentaries on classics down, and the drive pull bar is drop-down, torque arm is changeed down, drives push arm through rotating shaft, and push rod, isolating switch connecting lever are moved (opposite with the separating brake direction) to the combined floodgate direction of isolating switch, makes the isolating switch combined floodgate.
The good effect of conversion operation mechanism for high-voltage switch cabinet isolation switch of the present invention is:
(1) the vertical operation bar is away from a busbar, and making to prop up between busbar and the isolator operation parts in the high-tension switch cabinet has enough safety air spacings;
(2) simple for structure, rotate flexibly, on/off switch puts in place, reliable in function;
(3) good looking appearance, install easy to adjust, have certain versatility.
