Description
The invention relates to and be used for the adjustable transformer shunting switch, the on-load converting switch device of forming by speed changer and contact mechanism.
A kind of on-load diverter switch is disclosed in DE1207490, wherein, decide contact by device on a circular contact carrier, and movable normally closed interlock, main contact and auxiliary contact then are positioned on the garden arc shaped contact bearing of asymmetric setting, thus these movable contacts can be successively with decide contact and compress and contact.
This frame mode has many distortion, as shown in DE1221723 or DE1230903: the energy institute switch driven Control Shaft that is discharged by an energy storage device impels the contact brush that is placed on the power transmission shaft, contact lever, contact chip etc. to do the action of curved bar rod-type non-centrally, and this is the something in common of this type of switch.
Dynamic conversion is done in the simple rotation motion of these structures axle of generally all needing to rotate for this reason.
Therefore, do curved bar when operation, particularly when each contact action beginning, the speed that the contact disconnects, thereby that is the breaking capacity that reaches of maximum possible must be restricted.Situation just is, thereby the failure of current process (particularly when powerful electric current) at main contact place must be the whole contact disengaging movements that need finish as desire in whole switching manipulation process most critical parts in stage at first in the on-load diverter switch, and this moment, high responsiveness then directly was to guarantee the prerequisite of arc extinguishing reliably.
The switching device that is disclosed among the DE1228130 attempts to take following measures to avoid the shortcoming of this known on-load diverter switch, promptly not only be positioned at outer garden on week, and be positioned at garden week on main contact all can do mutually separately to move in opposite directions with mutually with auxiliary contact.By making every pair of two contacts that touch head mutually near improving switching speed; But the disc cams that is proposed realizes that the solution of operating of contacts is very expensive in mechanical aspects, and its exigent machining accuracy generally speaking is infeasible in practice.
DE1273677 discloses another kind of on-load diverter switch, has proposed second an instant shut-in mechanism of adding in order to improve switching speed, and it acts on the secondary contact of advocating peace of desiring to carry out switch.This device has a large amount of levers and is connected with hinge, and is equally also very expensive aspect processing, and when practice easy break-down.
Except restricted this shortcoming of the initial opening speed of the secondary contact of advocating peace, known on-load diverter switch also has a common shortcoming in addition, that be exactly these moving contacts in succession roll extrusion cross decide contact after, the switching manipulation of normally closed interlock is relevant with the burn situation of main contact, and this has brought difficulty to work.
Though see by DE1962958, adjacent position by normally closed moving contact rotatably being placed contact initiatively and independently control measure can avoid these shortcomings, but this structural measure is still very expensive in processing, and because additional rotary type setting and the more likelihood of failure that lies dormant.
Put it briefly, aforementioned this task that proposed of inventing that makes, promptly provided a kind of novel on-load diverter switch, it can directly utilize by energy storage device the rotatablely moving of switch driven axle that release energy and reach the initial opening speed of the resistance contact of advocating peace in the raising work, and the operation of the normally closed interlock of the no load switch of following will be irrelevant fully with the operation and the burn thereof of main contact.
