Described isolation ground connection interlocking and isolation load interlocking unit comprise grounded barrier, partitions, isolation indicator wheel, ground connection indicator wheel, isolate interlocking catch, switch output board, output toggle arm, cam, camshaft.The driving shaft of isolating indicator wheel connection isolating switch is isolated indicator wheel and is connected with grounded barrier is sealed, and the ground connection indicator wheel connects the driving shaft of earthed switch, and the ground connection indicator wheel is connected with partitions is sealed.Said camshaft is connected with the driving shaft of on-load switch; Cam is contained on the camshaft, and the cam of commentaries on classics is connected with output toggle arm, and output toggle arm connects switch output board one end; The switch output board other end connects isolates the interlocking catch, isolates the interlocking catch and is connected with partitions is sealed.After isolating switch closes a floodgate, isolate indicator wheel twist-lock grounded barrier, grounded barrier keeps off in ground connection operating axis the place ahead, and this moment can't the operational grounding switch.After earthed switch closed a floodgate, ground connection indicator wheel twist-lock partitions, partitions keep offs in isolated operation axle the place ahead, at this moment can't disconnecting switch operation; After on-load switch (circuit breaker) closes a floodgate; Camshaft drives the cam rotation; The knock over cam output toggle arm, output toggle arm drives the switch output board and rotates, and isolates the interlocking catch and moves with the switch output board; Isolate chain catch move after with partitions locking, can't operate this moment by isolating switch in isolated operation axle the place ahead for the partitions retaining.
The characteristics of the utility model:
1, this interlocking gear volume is little, and is easy for installation.
2, transmission is apart from weak point, and deviation accumulation is little.
3, operational torque is little, and is easy and simple to handle.
4, interlocking intensity is good, safe and reliable.
Need to prove: under the prerequisite of principle that does not change the utility model and design, change of being made or distortion all belong to the protection range
of the utility model.
