Abstract
The present invention relates to an isolating switch, particularly to a double-fracture folding vertical switching-on and switching-off isolating switch used for extra-high voltage or ultra-high voltage lines. A folding connecting rod with a parallelogram structure is used for replacing a straight-bar type connecting rod of the common vertical switching-off isolating switch; gears are used for replacing crank arms to transfer motive power to improve the accuracy and the stability of action; because a double-fracture form is used, the space height is reduced, the switching-off speed can be increased under the same switching-off power, and the effective use frequency is obviously increased.
Description
Technical field
The present invention relates to a kind of isolating switch, in particular for the double-breaks folding vertical disintegration isolation switch of superhigh pressure or extra-high voltage grid.
Background technology
Vertical breakaway-element isolating switch is the common equipment that is applied in the superhigh pressure transformer station, its operation principle is to utilize of being arranged on each phase line can vertically revolve the connecting rod that turn 90 degrees to connect the termination, connecting rod is the straight-bar of fixing, the rotation connecting rod makes its contact insert contact terminal during combined floodgate, during separating brake connecting rod is revolved to turn 90 degrees to lift to get final product.But because connecting rod is a straight-bar, connecting rod one end is suspended in the high-altitude during separating brake, and the moving contact insulation column will bear bigger torsion, the stability that influence is used; Simultaneously, when being used for supertension line, the volume of isolating switch is very huge, and it is very big to take up room behind the separating brake, and wind loading rating weakens; Inertial impact force was big when huge volume and long connecting rod made score, feed motion, caused mechanical failure easily; Just-off speed is slow, does not meet the requirement of divide-shut brake characteristic.Simultaneously, traditional vertical breakaway-element isolating switch adopts many group connecting lever type of drive, and complex structure, poor stability, action error are big, causes action not in place or cross action easily.
Summary of the invention
The purpose of this invention is to provide that a kind of inertia impact is little, the double-breaks folding vertical disintegration isolation switch of good stability.
For achieving the above object, the present invention adopts following technical scheme:
Double-breaks folding vertical disintegration isolation switch of the present invention comprises
Every have two fixing static contact and insulation pillars and a moving contact insulation column that is arranged between the two static contact and insulation pillars mutually, the top of static contact and insulation pillar is equipped with contact terminal, the top of moving contact insulation column is equipped with gear box, be provided with the power output shaft of level in the gear box, connecting rod is installed on the power output shaft;
Above-mentioned connecting rod comprises auxiliary arm and the actuating arm that is hinged in a parallel manner on the gear box and is hinged on auxiliary arm and the folding arm on actuating arm top, and the end of actuating arm is fixedly connected on the power output shaft, and the end of auxiliary arm is hinged on the gear housing; The top of auxiliary arm and actuating arm is hinged on the two ends of linking arm respectively, simultaneously, the top of auxiliary arm is by auxiliary arm jointed shaft fixed installation driving gear, the top of actuating arm is equipped with driven gear by hinge, driving gear and driven gear are meshing with each other, one end of folding arm is fixedly connected on the driven gear by the actuating arm jointed shaft, and another top has contact.
Auxiliary arm and actuating arm respectively have two, are installed in the both sides of gear box respectively abreast, and driving gear and driven gear are installed between the two by hinge.
Power output shaft is installed on the power output gear, and power output gear is in transmission connection by idler gear in the gear box and insulation column spinner.
After adopting technique scheme, this double-breaks folding vertical disintegration isolation switch has following advantage:
1, highly reduce more than 40%, conserve space, wind loading rating is strong;
2, inertia torque reduces, and can reduce the impulsive force to contact, improves the number of times of action message.
3, because length of connecting rod reduces, overcome the power reduction of gravity, under the situation of same separating brake power, just-off speed improves.
4, driving mechanism and connecting rod adopt gear drive to replace the transmissions of many group connecting levers, and error reduces, stability improves, move the accuracy height.
