Description
Technical field
The utility model involves in a kind of transmission device that is used for sub-connecting switch of transformer.
Background technology
Sub-connecting switch of transformer is a tap of finishing different gears by the mobile transposition of the moving contact in the switch rotating shaft, existing sub-connecting switch of transformer since structural reason when moving contact moves to the gear of a certain needs, do not have sound, make the operator can't determine that moving contact moves and whether put in place.
Summary of the invention
In order to solve the above-mentioned existing defective that is used for the transmission device on the sub-connecting switch of transformer, goal of the invention of the present utility model provides the transmission device on the sub-connecting switch of transformer of being used for that can send the sound that puts in place when a kind of moving contact moves into place.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of transmission device that is used on the sub-connecting switch of transformer comprises that flange, bottom be equipped with the rotating shaft of switch movable contact, sheave, support, rotating shaft, gear, support and gear; Rotating shaft and support are installed on the flange, and sheave is socketed in the rotating shaft, and rotating shaft and support are installed on the support, and gear is installed in the lower end of rotating shaft, and the gear driven gear rotates, and support links to each other with gear, and dead man and fork are housed on the gear; Be provided with spring, striker, pin and spring pin in the support, spring connects striker, sells an end and is connected on the striker, and the other end is installed in the support by spring pin, and the position of pin is corresponding with fork, and the position of striker is corresponding with the sidewall of support; Dead man on the gear and sheave interlock.
As preferably, be provided with axle between dead man and the sheave, dead man and sheave are by the axle interlock.
As preferably, fork is installed in the top of gear.
The utility model is owing to adopted a kind of transmission device that is used on the sub-connecting switch of transformer of technique scheme, the gear driven gear rotates when rotating shaft, gear drives dead man on the one hand and rotates, dead man drives sheave and rotates, sheave drives the rotating shaft that switch movable contact is housed and rotates, and reaches the purpose of transposing tap.On the other hand the fork on the gear when forwarding a certain angle to and pin contacts and pushing pin move, pin drives striker and moves, make length of spring compressed, when gear forwards predetermined angular to, fork and pin break away from, at this moment the unexpected resilience drive of compressed spring striker makes the wall of striker bump support and sends sound, and this sound is simultaneously when contacting fully with moving contact.In sum, when moving contact turns to the gear that needs, can send clearly sound, prompting operation person's switch puts in place, and this is used for transmission device on the sub-connecting switch of transformer and has put in place the advantage of sound prompting of driving torque is little, moving contact puts in place correctly, can send switch.
