Description
The utility model relates to a kind of isolating switch, particularly relates to a kind of superhigh pressure isolating switch.
In the high voltage power transmission and transforming road; often can use a kind of three pillar type high voltage isolator; fixed contact on transmission of electricity bus and the three pillar type high voltage isolator two ends support insulator links, and middlely moves with swinging strut porcelain vase drive conducting rod, realize circuit branch, close.In the ehv power transmission road, because voltage is more than 220KV, this just requires two distances between the fixed contact very big, support insulator also requires very high, like this, conducting rod on the middle rotation porcelain vase just needs very long, minute, conducting rod is very big to the impulsive force of two ends porcelain vase in the making process, simultaneously in the middle of the rotation porcelain vase also to bear very big moment of torsion.Therefore, when making this high voltage isolator with prior art, just used two support insulators in the centre, a support insulator plays a supportive role, and another post is used for rotation, has just increased cost so undoubtedly.
The purpose of this utility model provides a kind of superhigh pressure isolating switch, make its minute, in the making process, reduce the impulsive force of conducting rod, the moment of torsion of rotation porcelain vase in the middle of also reducing simultaneously to the two ends porcelain vase.
The purpose of this utility model, reach by the following technical programs: this superhigh pressure isolating switch, comprise base, an anchor post porcelain vase respectively is equipped with at the base two ends, shading ring and fixed contact are equipped with in its top, the swinging strut porcelain vase is housed in the middle of the base, shading ring and conducting rod are equipped with in its top, the conducting rod two ends are provided with moving contact, the drive unit that drives the rotation of swinging strut porcelain vase is housed on base, swinging strut porcelain vase top interconnects by universal head and conducting rod, and conducting rod middle part is sleeved in the sleeve versatilely, and a positioner that is used for controlling conducting rod axial rotation angle in sleeve is housed between this sleeve and the conducting rod.
Above-mentioned sleeve comprises train wheel bridge and lower plate, and last lower plate is bolted to connection.
Above-mentioned universal head comprises a connecting lever and a universal ball joint that is packed in swinging strut porcelain vase top, and universal ball joint one end is fixedlyed connected with connecting lever, and the other end is fixedlyed connected with the adapter sleeve on being fixed tightly in conducting rod.
Above-mentioned positioner is made up of spring strut, retainer spring, removable pin, spring capping, locking nut, retainer spring is contained in the spring strut, removable pin is contained in spring strut top and spacing by spring capping, spring capping and locking nut are screwed on the spring strut, removable pin flexibly connects by pivot pin and the adapter sleeve that is fixed tightly on the conducting rod, spring strut flexibly connects by a pivot pin and L shaped bearing one end, and the L shaped bearing other end is fixedly connected on the described sleeve.
One guide plate is housed on the fixed contact end face, and 45 ° of inclined-planes of inclination in the contact on one day are arranged at this guide plate bottom, and the fixed contact end face also is equipped with a block.
The utility model is with the driving force of middle swinging strut porcelain vase, be delivered on the conducting rod by a universal head, because conducting rod is installed in the sleeve, conducting rod not only can be horizontally rotated, and can in sleeve, rotate, and be provided with a positioner, be used to limit the angle that conducting rod rotates in upper and lower clamping plate.After adopting such scheme, conducting rod is horizontally rotated, make moving contact touch fixed contact, thereby conducting rod is turned an angle in sleeve moving contact is closely contacted with fingertip, process is then opposite during separating brake.So just make conducting rod less greatly to the impulsive force of two ends support insulator, the operating physical force of middle swinging strut porcelain vase also alleviates greatly, and moving contact and fixed contact contact stabilization, reliable, has improved through-current capability and useful life.Because the suffered power of middle swinging strut porcelain vase reduces greatly, therefore only need to use a swinging strut porcelain vase simultaneously, saved the support insulator that supports usefulness in the prior art, also reduced the cost of isolating switch.
