Abstract
The utility model relates to a loadless electric controlling voltage regulation switch. The utility model has the essential technical proposal that a rotary shaft of a groove shafting component is connected with a gear of a gear pair. A box body is connected with the other gear of the gear pair through a shaft which is fixedly connected with a cam. The utility model has the advantage that the groove shifting component of the shaft end of a deceleration torque motor positioned at a vertical shaft drives a grooved wheel to realize the position rotation of a central main shaft, shift tapping change and voltage regulation in one step. Shift position control is realized by the gear pair which drives the cam. The utility model has the advantages of simplified structure, high reliability and low cost.
Description
The utility model belongs to a kind of transformer switch, particularly a kind of automatically controlled voltage-regulation tap changer of no-load that is applicable to three-phase oil immersion.
Existing electronic control does not have on-load shunting switch mechanism more complicated, transmission link is many, by one group of a driven by motor (two) spur gear wheel as slowing down for the first time, carry out for the second time by one group of worm-and-wheel gear again and slow down, drive one group of Geneva mechanism then and realize that the tap conversion shelves of tap selector draw, because through repeatedly transmission, fluted roller shaft can not be in the center of entire mechanism, have to do idle wheel by one group of (two) straight spur gear again, the transmission of mechanism is indexed to central principal axis realizes tap displacement gear shift, gear shift control is to be controlled by a cam mechanism that is installed on the turbine, one week of turbine rotation is realized gear of tap conversion, the sensitive switch contact of certain position is fixed in cam lobe contact simultaneously and compressing, the normally opened contact dead electricity of the in running order closure of relay in the electrical control mechanism is opened circuit, the motor stall, switch is switched to gear, promptly realize the linear transformation gear, reach adjustment voltage, finish the one action circulation.
The purpose of this utility model provides the automatically controlled voltage-regulation tap changer of a kind of no-load, designs simplification, good reliability, and cost is lower.
The purpose of this utility model is achieved in that it comprises the electric control mechanism be made up of casing, case lid, sheave, slot poking ware, retarding moment motor, gear pair and sensitive switch etc. and by central principal axis, insulating bar, movable contact spring support, movable contact spring with decide the tap selector that contact etc. is formed, its technical scheme main points are: a gear that connects gear pair in the rotating shaft of slot poking ware, pass through another gear of axle attachment tooth wheel set on the casing, coaxial affixed cam.
The utility model has the advantages that: the slot poking ware by vertical axis position retarding moment motor shaft end drives the transposition of sheave one step realization central principal axis, and the tap shift is adjusted voltage, gear control realizes by gear pair drive cam, its designs simplification, reliability improves, and cost reduces.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
See Fig. 1, concrete structure is as follows: the retarding moment motor 7 of assembling vertical axis position on the case lid 5, and the retarding moment motor shaft end connects a travelling gear 9 of slot poking ware 8 and gear pair; The central authorities of casing 4 rotate by bearing and connect sheave 6, and slot poking ware 8 is stirred sheave 6 and rotated.Gear system is shown connection sensitive switch 12 on the contact fixing plate 13; Another travelling gear 10 of gear pair is contained on the casing 4 by the axle rotating group, the cam 11 that is fixedly connected on coaxial, and cam 11 can touch sensitive switch 12.The below of sheave 6 connects the central principal axis 3 of bakelite, and several bakelite insulating bars 14 are set around the central principal axis 3; The branch upper, middle and lower three layers of movable contact spring support 15 that are fixedly connected on the central principal axis 3 connect movable contact springs 1 by drift bolt 16 and little spring 17 on each movable contact spring support 15.The branch upper, middle and lower are fixedly connected three layers and decide contact 2 on the bakelite insulating bar 14.
Operation principle: press starting button and make the retarding moment motor rotation, drive its axle head slot poking ware 8 operations, stir sheave 6 and rotate, do to rotate with angular speed thereby drive central principal axis 3, movable contact spring 1 conversion displacement realizes contacting with the conversion of deciding contact 2 that is fixed on each diverse location of circumference; Motor shaft driven gear pair makes cam 11 do regular the rotation simultaneously, and cam 11 feelers are periodically oppressed sensitive switch 12, make motor 7 dead electricity, stop to finish a duty cycle, realize the changing-over shift of dynamic/static contact, thereby transformer is adjusted voltage.
Claims (1)
1, the automatically controlled voltage-regulation tap changer of a kind of no-load, comprise the electric control mechanism formed by casing, case lid, sheave, slot poking ware, retarding moment motor, gear pair and sensitive switch etc. and by central principal axis, insulating bar, movable contact spring support, movable contact spring with decide the tap selector that contact etc. is formed, it is characterized in that: a gear that connects gear pair in the rotating shaft of slot poking ware, pass through another gear of axle attachment tooth wheel set on the casing, coaxial affixed cam.
