The invention relates to the technical field of an outdoor AC high-voltage isolation switch, specifically a transmission system of the outdoor high-voltage isolation switch. The system comprises a frame beam, a switch mechanism, a main cutter, an insulation pillar, a connection base, a conductive pipe, a moving contact and a static contact, wherein a drive mechanism is connected with a vertical transmission link, which is connected with a transmission regulation crank of the main cutter arranged in the frame beam; the transmission regulation crank of the main cutter is connected with a first-stage transmission link, which is connected with the transmission regulation crank, which is connected with a main transmission shaft, which is respectively connected with six regulation cranks; two second-stage transmission rods of each phase are connected with the transmission regulation crank; and the two second-stage transmission rods of each phase are connected with the transmission regulation crank below the rotation shaft in a bearing pedestal. The rotation joint of the inventive transmission system is prevented from the direct corrosion of the rain and the snow, and the direct irradiation of the sunlight, thereby improving the anti-rust capacity of the transmission joint, and the six rotation shafts of three phases are applied with uniform force. The inter-phase transmission travel is not influenced by the temperature difference, and the operation is more flexible and reliable.
Description
Technical field:
The present invention relates to the high-voltage alternating current isolating switch technical field, it is a kind of drive system of outdoor AC high-voltage isolating switch in definite saying.
Background technology:
The outdoor high-voltage isolating switch that electric power system at present adopts, its drive system is the version of twentieth century, drive system is all exposed in the space.Because air quality descends, erosion is embroidered in the joint of drive system easily, exposes in the drive system in space and in a single day embroiders erosion, will have a strong impact on the carrying out of switch operation.The push-and-pull kind of drive of alternate transmission connecting leg, affected by environment bigger, area especially northeastward because summer in the winter temperature difference is big, summer its temperature can reach 40 degree, its surface temperature can reach-40 degree in the winter time.In the 220kV electrical voltage system, the phase spacing of isolating switch is 4 meters.It is more than 10 millimeters that the temperature difference of 80 degree can cause 4 meters long connecting leg length variations, has therefore destroyed the synchronism of isolating switch, makes water conservancy diversion loop cisco unity malfunction.More than 2 bring hidden danger all can for the safe operation of electric power system.In addition, run into bad weather, floating ice easily knot can't carry out grid switching operation on connecting rod and driving joint, brings hidden danger to system safety operation.
Summary of the invention:
The purpose of this invention is to provide the safe and reliable drive system of a kind of outdoor high-voltage isolating switch.It will expose in the joint of the drive system in space is installed in semiclosed or totally enclosed crossbeam.Make it not to be subjected to the direct erosion of rain, snow and the direct projection of sunlight, improve the driving joint reliability of action flexibly.In order to reach this purpose, the push-and-pull kind of drive of alternate transmission connecting leg changes the rotation kind of drive of transmission tube into.Avoided the not problem of the same period or dynamic and static contact loose contact of the three-phase that caused by temperature difference problem.Can resist the erosion of extreme natural environments such as rain, snow.1, outdoor high-voltage isolating switch, described isolating switch is a three-phase, it comprises housiung separator, switching mechanism, operator, insulation column, junction block, contact tube, moving contact and fixed contact, it is characterized in that: driving mechanism 1 is connected on the vertical drive link 2, and vertical drive link 2 is connected on the operator transmission crank arm 3 that is installed in the housiung separator 11; Operator transmission crank arm 3 connects one-level kinematic link 4, and one-level kinematic link 4 is connected on first transmission crank arm; First transmission crank arm connects transmission main shaft 6, and transmission main shaft 6 is connected with three pairs second transmission crank arm respectively, and every pair of described second transmission crank arm is respectively one by one corresponding to each phase in the described three-phase; Described each all have mutually two secondary drive links 8, one of them described secondary drive link 8 with described each in mutually, be connected with corresponding one second transmission crank arm of a described described secondary drive link 8; Another described secondary drive link 8 with described each in mutually, be connected with corresponding another second transmission crank arm of described another described secondary drive link 8; The secondary drive link 8 of every phase is connected on the folding transmission crank arm 9 under the rotating shaft 10 in the bearing pedestal; Alternate transmission is for rotating transmission.All the joint of drive system is installed in the semiclosed or totally enclosed housiung separator 11.The operator of middle and upper part of the present invention is divide-shut brake under folding transmission crank arm 9 drives, and its mode is identical with existing high voltage isolator with structure.Ground knife switch mechanism is also identical with existing high voltage isolator ground knife switch structure, the drive system design ground knife switch mechanism that also can adopt the present invention to operate.
Advantage of the present invention is: because the joint of drive system is installed in the semiclosed or totally enclosed crossbeam, the cradle head of drive system all can not be subjected to the direct erosion of rain, snow and the direct projection of sunlight, improve the rust-proofing ability of driving joint, prolonged the time between overhauls(TBO).Make and operate more flexibility and reliability.The particularly alternate kind of drive becomes rotating manner, and the total kilometres of transmission link are not acted upon by temperature changes, and has guaranteed that the total kilometres of isolating switch transmission are stablized constant.Increased substantially the reliability of isolating switch.
