Description
The present invention relates to a kind of by first described job selector job selector dial that is used for the stepping adjustable transformer of claim preamble.
By the known this job selector job selector dial of DE3833126C2.
In transformer, job selector job selector dial is used for the adjusting tapping and thereby the variation of bucking voltage correctly of this transformer of changing-over under load.
Job selector job selector dial can be made and use more economically, because exempted otherwise separating selector and load transition switch traditionally.
Switching process produces electric arc on the different contact in job selector job selector dial.For fear of electric arc occurring, in above-mentioned DE3833136C2, advised a kind of job selector job selector dial, wherein, each to connect mutually in a public contact supporting, establish two can simultaneously common gyration the mechanical switch contact, and respectively establish one with each of two movable mechanical switch contacts with aligning and be contained in the vacuum interrupter chamber that this contact supports equally.
Job selector job selector dial can be arranged in by the fixedly otch of rotary machinery switch contacts on the concentric circles in the insulating material cylindrical wall.
Some vacuum interrupter chamber levels are arranged in flatwise on the contact supporting plate and can be by being arranged in controlling or manipulation at the circle of fixing otch and the cam working face between the additional slip ring vertically on another concentric circles.
This known job selector job selector dial has many shortcomings.
At first, owing to vacuum interrupter chamber is flatly arranged flatwise, cause insulating material cylinder and thereby the undesirable big diameter of job selector job selector dial in public contact supporting.
Vacuum interrupter chamber depends on that its switch power has the minimum dimension of regulation, especially also has big longitudinal size.In addition, also have joystick longitudinally to stretch out from vacuum interrupter chamber.Therefore it is evident that whole contact supporting must have a radial dimension by the size decision of vacuum interrupter chamber and operating mechanism, it finally determines the diameter of job selector job selector dial.
From this total dimensional problem, under the situation that vacuum interrupter chamber is installed by the prior art level, exist an outstanding shortcoming, promptly the upper corrugation place at the vacuum chamber bellows leaves air when job selector job selector dial refuels, and fully it is not supplanted by refueling.This can cause, and corresponding vacuum chamber bellows produces unequal loading when handling vacuum interrupter chamber, thereby has the danger that makes it to break.
This retention of residual air in the aneroid capsule district has only when arranging flatwise by job selector job selector dial and refuels under vacuum and could reliably avoid; Yet for example after implement checking, this vacuum filling can not or have only with thundering high cost and could realize at the scene.
Should be taken into account that in addition job selector job selector dial has a big vertically longitudinal length usually generally, that is to say huge structure height.The fixedly otch of each phase of connecting is arranged above and below circularly, be used to handle and be located at that the job selector job selector dial interior support the rotatable switch shaft of contact supporting of each phase and the device that is disposed in the mechanism of job selector job selector dial head and is used to support this switch shaft in the job selector job selector dial bottom needs the locus equally, thus stack up as already described like that this job selector job selector dial huge longitudinal size is arranged.Consequently, the switch shaft of mentioned portion within it is equally quite long.
This switch shaft is made with GFK or other insulating material usually, also once advises the switch shaft of metal certainly.
The contact supporting is fixed on the switch shaft with hold-down screw in known job selector job selector dial.
In DE4414941C1, introduced by means of clamping flange the contact supporting has been fixed on the switch shaft more firmly.
Because the thermal expansion that tolerance, oil conservator are different with switch column, bending etc., member in known job selector job selector dial on being contained in the supporting of each contact may produce difficulty when especially vacuum interrupter chamber is with the operating mechanism co-operating of arranging circularly, especially also because the joystick of vacuum interrupter chamber has only a smaller linear operating stroke usually.
The objective of the invention is to get rid of these shortcomings and a kind of job selector job selector dial by this type is provided, its allow to be saved ground, position and arranges vacuum interrupter chamber and can be safely under all service conditionss and handle them reliably.
The job selector job selector dial of the feature of this purpose by having first claim reaches.
Dependent claims relates to the particularly advantageous development of the present invention.
Vacuum interrupter chamber is erected to be installed in the contact supporting in job selector job selector dial of the present invention.Contact is supported with sliding contact, and they are by roller accurately guiding in drawing ring.Vacuum interrupter chamber is controlled by the cam in this draws ring.
The cutter formula sliding contact that is contained in the contact supporting is drawn electric current by drawing ring.
Other cutter formula sliding contacts in the contact supporting can input current.
By another feature of the present invention, the contact supporting is contained on the switch shaft respectively movingly.
By the outstanding advantage of job selector job selector dial of the present invention, except size was less, the whole power and the contact force that are used to handle vacuum interrupter chamber were all passed to firm oil conservator vertically by drawing ring and fixed contact.Avoid the radial load of switch column thus, especially avoided reducing of its bending and vacuum interrupter chamber control time change that causes thus and contact force.
Adopt rotatable and axially movably supporting and, even in that the thermal expansion different with switch column causes along still guaranteeing switching process under the situation of offsets in height with oil conservator owing to tolerance axially by drawing the contact supporting of ring guiding.
