Abstract
The present excitation-free electric cage-shape tap switch. The operation control mechanism of mechanical transmission device adopts cooperation of rotary insulation partition and double spring contact switch. The double spring contact switch is composed of mutually corresponding upper and lower contact fixed in insulator. It is not easy to be failure due to wetting and rust which can ensure the normal start or stop of electric machine.
Description
Technical field
The utility model relates to the transformer switch device, is that a kind of transformer of finishing the tap conversion does not have the electronic cage type tapping switch of excitation.
Background technology
Operation controlling organization in existing its mechanical transmission mechanism of the electronic cage type tapping switch of no excitation is to adopt rotating shaft and press-type travel switch cooperating, its useful life is short, not only the contact is easy to wear in the work, and travel switch is influenced greatly by environmental interference, travel switch moisture-sensitive corrosion, aging malfunctioning, influence the operate as normal of travel switch, cause normally start and stop work of driving motor, directly the electronic cage type tapping switch operate as normal of the no excitation of influence.
The utility model content
The purpose of this utility model is to improve at the above-mentioned deficiency of prior art, provides a kind of service-strong not have the electronic cage type tapping switch of excitation.
The technical solution of the utility model is that the operation controlling organization in the mechanical transmission mechanism of the electronic cage type tapping switch of no excitation is adopted rotating insulated partition 9 and two-man act contact switches device cooperating, and two-man act contact switches device is made of the contact up and down 1,2 that is fixed on the mutual correspondence in the insulator.
The rotating insulated partition 9 of the utility model cooperates with contact 1,2 up and down, the gram shortcoming of prior art, and the moisture-sensitive corrosion is not malfunctioning, long service life, reliable working operation can guarantee normally start and stop work of driving motor, guarantees the electronic cage type tapping switch operate as normal of no excitation.
Description of drawings
Fig. 1, the 2nd, the utility model do not have the electronic cage type tapping switch structural representation of excitation, and wherein Fig. 2 is that the K of Fig. 1 is to view.
Fig. 3 is the A-A cutaway view of Fig. 2.
Fig. 4 is the B-B cutaway view of Fig. 3.
Embodiment
The utility model does not have the mechanical transmission mechanism that the electronic cage type tapping switch of excitation includes tap mechanism 3, adpting flange 4, is made up of support 50, motor 51, Worm and worm-wheel gearing 52, rotating shaft 53, shift fork 54, dial 55, axis 56, it is characterized in that being provided with insulating spacer 9 and cooperate with two-man act contact switches device on rotating shaft 53, two-man act contact switches device is made of the contact up and down 1,2 that is fixed on the mutual correspondence in the insulator.Shown in Fig. 3,4, two-man act contact switches device is by contact 1,2, upper, middle and lower insulating frame 21,22,23 are formed up and down, insulating frame 21,23 is fixing respectively with up and down by screw or rivet 24,25 for contact 1,2 up and down, on insulating frame 21,23 up and down, be respectively equipped with spring 26,27 and act on the leading section of contact 1,2 up and down, make up and down that contact 1,2 front ends keep stationary contact to close shape, upper, middle and lower insulating frame 21,22,23 is mutually permanently connected by screw 28.Two-man act contact switches device is fixed on the support 50 of motor 51, Worm and worm-wheel gearing 52 transmission devices.
During the utility model work, when shunting switch is not changed, insulating spacer 9 on the rotating shaft 53 is in contact 1 up and down, 2, to contact 1 up and down, 2 separately, when shunting switch is changed, motor 51 rotates insulating spacer 9 rotations that drive on the rotating shaft 53 and breaks away from the two-man act contact switches, contact 1 up and down, 2 touch and close, signal output, electric control gear control motor remains in operation, and incites somebody to action contact 1 up and down in the two-man act contact switches when the insulating spacer on the rotating shaft 53 9 returns back to, 2 separately the time, signal output, the motor stall, tap mechanism finishes once conversion under the transmission of transmission mechanism.
