Abstract
The invention relates to the technical field of alternative current high-voltage isolators, in particular to a high-voltage isolator which comprises a machine frame cross beam, a switch mechanism, a main cutter, an isolating pillar, a wiring base, a conducting tube, a movable contact and a fixed contact, wherein a driving mechanism is connected onto a vertical transmission connection rod which is connected onto a main cutter transmission connecting lever installed in the machine frame cross beam, the main cutter transmission connecting lever is connected with a primary transmission connection rod which is connected onto the transmission connecting lever, the transmission connecting lever is connected with a main transmission shaft which is respectively connected with six connecting levers, and the transmission connecting levers are connected with two primary transmission rods of each phase, two secondary transmission rods of each phase and a transmission connecting lever under a rotating shaft in a bearing base. A rotating joint of the transmission system of the high-voltage isolator cannot be directly eroded by rain and snow and can be kept out of the sun, the anti-rust capability of a transmission joint is improved, and six rotating shafts of three phases are even in stress. Routines are transmitted between the phases in rotating mode, so that temperature difference influence can be avoided, and operation is flexible and reliable.
Description
Technical field
The invention belongs to the high-voltage alternating current isolating switch technical field, it is a kind of drive system of alternating-current high-voltage isolation 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 easily embroidered in the joint of drive system, and in a single day exposed drive system in the space 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 larger, especially northeastward the area, because summer in the winter temperature difference is large, summer its temperature can reach 40 the degree, in the winter time its surface temperature can reach-40 the degree.In the 220kV electrical voltage system, the phase spacing of isolating switch is 4 meters.Can to cause the connecting leg length variations of 4 meters long be more than 10 millimeters to the temperature difference of 80 degree, therefore destroyed the synchronism of isolating switch, makes water conservancy diversion loop cisco unity malfunction.Bring hidden danger all can for the safe operation of electric power system at above 2.In addition, run into bad weather, floating ice easily knot on connecting rod and driving joint, can't carry out grid switching operation, brings hidden danger to system safety operation.
Summary of the invention
The purpose of this invention is to provide a kind of high voltage isolator.It is installed in the joint of exposed drive system in the space 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.
A kind of high voltage isolator that the present invention proposes, described isolating switch is three-phase, comprises housiung separator, switching mechanism, operator, insulation column, junction block, contact tube, moving contact and fixed contact; Driving mechanism is connected on the vertical-transmission link rod, and the vertical-transmission link rod is connected on the operator transmission crank arm that is installed in housiung separator; The drive link of every phase is connected on folding transmission crank arm under rotating shaft in bearing pedestal; Alternate transmission is for rotating transmission.
High voltage isolator of the present invention, all the joint of drive system is installed in semiclosed or totally enclosed housiung separator.
The invention has the beneficial effects as follows: because the joint of drive system is installed in 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, extended the time between overhauls(TBO).Make and operate more flexibility and reliability.Particularly the 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.
Description of drawings
Further set forth the present invention below in conjunction with accompanying drawing and case study on implementation.
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with embodiment, a kind of isolating switch of the present invention is described.
Embodiment 1.
As shown in Figure 1, high voltage isolator, described isolating switch is three-phase, comprises housiung separator, switching mechanism, operator, insulation column, junction block, contact tube, moving contact and fixed contact; Driving mechanism 1 is connected on vertical-transmission link rod 2, and vertical-transmission link rod 2 is connected on the operator transmission crank arm 3 that is installed in housiung separator 4; The drive link of every phase is connected on folding transmission crank arm under rotating shaft in bearing pedestal; Alternate transmission is for rotating transmission.All the joint of drive system is installed in semiclosed or totally enclosed housiung separator 4.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
