Abstract
The utility model relates to a switching and selecting synchronous device for a loaded tapping switch, composed of an energy storage fast releasing mechanism, a timing mechanism and a power transmission speed reducing mechanism. A driving plate 17 and an energy storage plate 18 form a pair of indivisible coupling components, wherein, a common shaft 12 between which can correspondingly rotate in 180 DEG. A rotating plate 30, a big gear wheel 28 and a gear wheel 7 form an indivisible group. A common shaft 32 of the rotating plate 30 and the big gear wheel 28 can rotate correspondingly in 180 DEG. Two power transmission mechanisms respectively poke grooved wheels 22, 2 through poking pins 16, 4. Thus, power is transmitted to a switching switch and a selecting mechanism for achieving synchronization. When a spring 21 is out of action, switching and tipping selections still can realize synchronization in low speed motion under the drive of the power of a motor.
Description
The utility model be mainly used in the supporting on load tap changer of power transformer in control switch and select synchronous device.
Existing on load tap changer with a motor as power source, the spring in the stored energy mechanism of its drive diverter switch is in a single day inoperative, and diverter switch and tap selection mechanism just can not realize synchronization action; And stored energy mechanism when switching formed impact noise big, locating part is easy to wear, complex structure, cost height.Adopt the be used as power on load tap changer in source of two motors, though it is without spring energy-storage, generally speaking also can be synchronous, its control circuit complexity, the chance that breaks down is still more.
The purpose of this utility model is still to use a motor as power source, adopting the control of sheave stored energy mechanism to switch with selection makes it synchronous, this mechanism still can make switching and tap select to realize synchronization action with low-speed motion under the drive of motor power under the ineffective situation of spring.And it is simple again not have impact noise, structure.
The utility model is released mechanism, timing mechanism, power transmission reducing gear soon by energy storage and is formed.Energy storage is released mechanism soon and is made up of axle 12, gear 13, connecting rod 14, eccentric wheel 15, finger 16, dial 17, energy storage dish 18, rotating disk 19, axle 20, spring 21, sheave 22, gear 23, fixed axis 24, seat board 25, axle 26,27.Timing mechanism is made up of sheave 2, rotation axis 3, finger 4, bearing pedestal 5, axle 6, gear 7, dial 8, gear wheel 28, seat board 29, rotating disk 30, sliding sleeve 31, axle 32.The power transmission reducing gear is made up of reduction box 9, motor 11, and reduction box 9 is made up of other parts such as axle 10, bevel gear 36,37, worm screw 35, worm gears.Wherein dial 17 is a pair of indivisible even parts with energy storage dish 18, and coaxial 12 can relatively rotate 180 ° between two.Rotating disk 30, gear wheel 28, gear 7, dial 8 are one group of indivisible combination, and rotating disk 30 can relatively rotate 180 ° with gear wheel 28 coaxial 32.Being fixed on finger 16 on the dial 17 can stir sheave 22 power is passed to diverter switch; Being fixed on finger 4 on the dial 8 can stir sheave 2 power is passed to tap selection mechanism.When spring 21 lost efficacy, cannelure 39 ends of the circle of 3/4 on the energy storage dish 18 drove the arc boss 47 of 1/4 circle on the dial 17 and rotate at a slow speed, reach power is passed to diverter switch, make it to select synchronously with tap.
The utility model is with a motor as power source, that can realize well switching under the situation that energy storage spring did not lose efficacy and select be synchronous, even under the ineffective situation of energy storage spring, it still can make switching and tap select to realize synchronization action with low-speed motion under the drive of motor power.Guarantee without the Electrical and Electronic control appliance, so it has no impact noise, simple in structure, cost is low, Installation and Debugging are easy, safe and reliable advantage.
