Abstract
The invention relates to the high-voltage electrical field, and particularly relates to a compact isolating switch. The compact isolating switch comprises a cylinder body, a moving end conductor, a moving contact, an opening and closing drive mechanism used for driving the moving contact to move, and a static contact. The moving contact is assembled in the moving end conductor in an axial movement mode, is in rotation stop fit with the moving end conductor, and is provided with a center hole which runs through in the axial direction. The opening and closing drive mechanism is a screw-nut mechanism, the screw of the screw-nut mechanism extends into the center hole of the moving contact, and the nut and the moving contact are assembled together. During use, rotation of the screw can be converted into axial linear movement of the nut and the moving contact through the screw-nut mechanism, and the screw does not do axial movement in the moving process of the moving contact. Therefore, the needed space of the isolating switch in the axial direction of the screw is saved, the size of the isolating switch is reduced, and the problem that an existing isolating switch is large in size and cannot be miniaturized is solved.
Description
Technical field
The present invention relates to field of high-voltage electrical equipment, particularly relate to a kind of compact isolating switch.
Background technology
Isolating switch is element important in high-voltage switch gear system, combined with other functional units in GIS product, realizes the effect of high-voltage switch gear in electric power system.
The evolution of isolation earthing switch, all the time along with the evolution of electric power system to the performance requirement of high-voltage switch gear product.Along with expanding economy, industrialized progress, the performance requirement of electric power system to high-voltage switch gear improves constantly.Network system requires to possess high reliability, just requires that product possesses higher Mechanical Reliability and stability.Modern society requires that industrial development and natural environment develop in harmony, also makes product to take into account environmental friendliness.
The requirement of electric power system, the development trend of industry, all impel a kind of structure technology of development advanced, the lightweight isolation earthing switch of performance parameters excellence is very necessary.
Development trend both domestic and external shows, GIS isolation earthing switch, just along the future development of lightweight, high parameter.Product size is progressively reducing, and arrangement form is also tending towards flexible.
The moving contact of existing isolating switch and fixed contact point, to close a floodgate be all controlled by an insulated tension pole, the reciprocating motion of insulated tension pole certainly will need to occupy certain space in the corresponding direction, this then limits reducing further of isolating switch overall dimension, and existing isolating switch still also exists the problem that overall dimension is large, cannot realize miniaturization.
Summary of the invention
The object of the present invention is to provide a kind of compact isolating switch, the problem large with the size solving existing isolating switch, miniaturization cannot be realized.
In order to solve the problem, compact isolating switch of the present invention is by the following technical solutions: compact isolating switch, comprise cylindrical shell, moved end conductor, moving contact, for ordering about divide-shut brake driving mechanism and the fixed contact of moving contact activity, what moving contact was axially movable is assemblied in the conductor of moved end, described moving contact coordinates with moved end conductor is spin-ended, moving contact is provided with axially through centre bore, described divide-shut brake driving mechanism is screw-nut body, the leading screw of screw-nut body stretches in the centre bore of moving contact, and nut and moving contact are fixedly assembled together.
The lead screw transmission of screw-nut body is connected with insulating driving rod.
Described moved end conductor is dihedral conductor, moved end conductor by be located at moving contact radial direction place, fixedly the insulation basin be assemblied on cylindrical shell be assemblied in cylindrical shell.
Described moved end conductor is square conductor.
The outside of described moved end conductor is provided with moved end radome, and one end be connected with leading screw of insulating driving rod is housed among the radome of moved end.
One end place away from leading screw in insulating driving rod on described cylindrical shell is provided with bar radome, and one end away from leading screw of insulating driving rod is housed in bar radome.
Because the moving contact of compact isolating switch of the present invention coordinates with moved end conductor is spin-ended, moving contact is provided with axially through centre bore, and divide-shut brake driving mechanism is screw-nut body, the leading screw of screw-nut body stretches in the centre bore of moving contact, and nut and moving contact are fixedly assembled together.Therefore, when in use, the rotation of leading screw can be converted into the axial linear movement of nut and moving contact by screw-nut body, and in the process of moving contact motion, leading screw is without axial motion, thus isolating switch can be saved in the upwards required space of lead screw shaft, reduce the size of isolating switch, the size solving existing isolating switch is large, miniaturized problem cannot be realized.
Further can be shortened the length of leading screw by the design of insulating driving rod, while the cost reducing isolating switch, its isolation performance can also be improved; Dihedral conductor further ensures the compactedness of isolating switch structure, can realize reducing further of isolating switch size.
