When movable touch knife inserts pincerlike contact, electric current through pincerlike contact, movable touch knife and double loop be flexible coupling, terminal block forms path.The employing double loop is flexible coupling, and is the needs that satisfied heat radiation, electric life and the mechanical endurance of movable position conductor when movable touch knife rotates.This isolating switch body detects institute in July, 2011 in the Zunyi product quality inspection and has passed through type approval test as on the GGN-15/4000 track traffic isolating switch.

Compared with prior art, the utlity model has following characteristics:

1, the movable touch knife that is directed against existing isolating switch is in the little shortcoming of poor electric contact, the through-current capability of its hinged place; Be connected through bolt crimping mode by soft multilayer build-up copper sheet between the utility model movable touch knife and the terminal block; Thereby it is big to have contact area, and contact site pressure is big; Contact resistance is littler, the characteristics that through-current capability is bigger.Simultaneously, the double loop of multilayer build-up copper sheet is flexible coupling for existing articulated structure, has that heat-sinking capability is strong, the advantage of longer service life.

2, for convenience detach, assembling, adaptability is strong

When current capacity is big, can suitably increase the number of the pincerlike assembly in unit;

When current capacity hour, can suitably reduce the number of the pincerlike assembly in unit.

Contact pressure is big when 3, matching with external contact knife, contact resistance is little

When external contact knife moves upward the pincerlike contact of insertion, two row's fingertips will open to both sides along the curved arrow direction.The pressure of extension spring compresses the contact-making surface of external contact arm and external contact knife the two ends of fingertip simultaneously.During work, electric current passes through external contact knife, pincerlike contact, and external contact arm forms path.When external contact knife withdrawed from pincerlike contact, power supply was disconnected.

4, this device integrates manual, electronic, locking three kinds of patterns, every kind of pattern and carries out separately, do not disturb mutually, has perfect machinery and electrical interlock function

When operating grip is not pulled out, can not carry out electric operating.When operating grip was not pulled out, sliding shaft sleeve blocked the model selection locking bar, and push pedal, model selection locking bar and divide-shut brake position locking bar can only remain on rightmost, so the pattern knob can only remain on manual position, can not rotate.Simultaneously, the manual position switch breaks off control loop, and provides signal.

5, when the pattern knob places electronic position, can not carry out manual operation.When the pattern knob placed electronic position, the model selection locking bar pinned sliding shaft sleeve, and operating grip can not be pushed in the mechanism by force, so, can not carry out manual operation.Simultaneously, electronic position switch is connected control loop, and provides signal.

6, when the pattern knob places latched position, manual and electric operating all will be under an embargo.When the pattern knob placed latched position, the model selection locking bar pinned sliding shaft sleeve, and operating grip can not be pushed in the mechanism by force, so, can not carry out manual operation.Simultaneously, the latched position switch breaks off control loop, and provides signal, therefore, also can not carry out electric operating.And, have only when Switch main body is positioned at separating brake or closing position, divide, close the position locking bar and could insert in the interlock plate, push pedal, model selection locking bar and divide-shut brake position locking bar just can remain on Far Left, and the pattern knob just can rotate to latched position.

Steel ball in clutch side's cover can be pressed in the pit (two) of sliding shaft sleeve under the effect of spring, the state that makes bevel gear wheel and bevel pinion keep engagement and throw off.Bolt can be regulated the dynamics that the manual operation plate pushes or pulls out.
