Abstract
The utility model discloses a vacuum on-load tap-changer gear converter, pertaining to the field if electromechanical technology, to solve the problem in the existing technology that the gear converter of the vacuum on-load tap-changer has more complicated structure and high requirement to the parts. The vacuum on-load tap-changer gear converter includes a sliding device, a stand in fixed connection to the sliding device, a movable contact in fixed connection to the stand, and a stationary contact, wherein the sliding device drives the stand and the movable contact to do a rectilinear movement at the pulling force action of the switching device of the vacuum on-load tap-changer, when the movable contact moves to an enactment position, the movable contact reliably contacts with the corresponding stationary contact to achieve the gear switch. The object of the utility model is that the movable contact of the switch converter adopts rectilinear movement modus, the movable contact moves left and right driven by the sliding device to contact with the stationary contact at corresponding position, to realize switch converting, the apparatus abolishes the intermediate conversion link, has simple structure and the parts are easy to process.
Description
Technical field
The utility model relates to the mechanical ﹠ electrical technology field, particularly relates to a kind of vacuum on-load operation switch gear transducer.
Background technology
The vacuum on-load operation switch of manufacturer's production at present, its gear conversion is a slider-crank mechanism normally, and moving contact is done circular motion around a fixed pivot and is realized the gear conversion.Its concrete structure is to adorn a fixed pivot on the switch mounting panel, there is the shift fork of chute to be contained on the fulcrum, slide block on the arm-tie is contained in the chute, when trying hard to recommend of switch quick mechanism output moved the arm-tie side-to-side movement, slide block drives shift fork around support motion, and moving contact is contained in the other end of shift fork, realizes the conversion of switch gear thereby slides in fork slot by slide block, this class gear conversion device structure is comparatively complicated, part is required high.
The utility model content
The utility model provides a kind of vacuum on-load operation switch gear transducer, and is comparatively complicated in order to the gear conversion device structure that solves vacuum on-load operation switch in the prior art, to the demanding problem of part.
A kind of vacuum on-load operation switch gear transducer of the present utility model comprises: carriage, the support of fixedlying connected with carriage, the moving contact of fixedlying connected with support, and fixed contact; Under the switching device shifter tension of vacuum on-load operation switch, described carriage drives support and moving contact rectilinear motion, when moving contact moves to desired location, reliably contacts with corresponding fixed contact, finishes the gear conversion.
Further, described carriage comprises: arm-tie, roller and linear pattern chute, and wherein arm-tie is fixedlyed connected with roller, and roller and linear pattern chute are slidingly connected, and arm-tie is fixedlyed connected with described support.
The utility model beneficial effect is as follows:
The purpose of this utility model is the moving contact of switch transition device is adopted rectilinear motion mode, moving contact contacts with the fixed contact of relevant position after side-to-side movement under the drive of carriage, thereby realize the conversion of switch, this device cancellation intermediate conversion links, it is simple in structure, and part is easy to processing.

Embodiment
The utility model is an important conversion equipment of vacuum on-load operation switch, and vacuum on-load operation switch basic functional principle such as Fig. 1: when switch is received the entry into service of switching signal rear motor, gearcase 1 passes to corresponding moment respectively the switching of switch and selects part by three gear stages; Thereby the power transmission shaft of switching part 2 obtains being with draw-gears 4 side-to-side movements to realize the switching of switch by quick mechanism 3 after the corresponding moment; Select the drive link 9 of part to obtain passing through the correct selection that bevel gear 8, screw mandrel 6 and nut 7 are realized the switch gears after the corresponding moment.
Below in conjunction with above-mentioned accompanying drawing example, the utility model Fig. 1 dashed rectangle partly is described in further detail.Referring to Fig. 2 and shown in Figure 3, the utility model vacuum on-load operation switch gear transducer is made of arm-tie 10, roller 11, chute 12, support 17, moving contact 13, first fixed contact 14, second fixed contact 15, the 3rd fixed contact 16, mounting panel 18.
The utility model vacuum on-load operation switch gear transducer operation principle is as follows: when quick mechanism 3 drives draw-gear 4 side-to-side movements, roller 11 horizontally slips in linear pattern chute 12, moving contact 13 and support 17 side-to-side movement under the drive of arm-tie 10, and first fixed contact 14 selects part odd number group contact to be connected with switch, second fixed contact 15 selects part even numbers group contact to be connected with switch, and the 3rd fixed contact 16 is connected with switch master break-make vacuum interrupter; When moving contact 13 is positioned at right side (i.e. first desired location), even numbers group contact and main break-make vacuum interrupter are connected, when moving contact 13 was positioned at left side (i.e. second desired location), odd number group contact and main break-make vacuum interrupter were connected, thereby realized the alternately conversion of single, double group of contact of switch.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
