Background

Among the 10kV distribution network equipment, outdoor distribution equipment all need to have a power failure when the maintenance, can be furnished with the isolation switch of integral type on the general switch of fracture for there is visual isolation. The locking logic between the isolation knife switch and the switch body is as follows: when the switch is in an opening state, the locking rod is unlocked, and the isolating knife can be freely opened and closed; when the switch is in a closing state, the locking rod is in a locking state, and the isolating knife cannot be freely opened and closed.

In the scheme adopted at present, too many isolation and locking conduction links exist, the conduction distance is too long, if one conduction link goes wrong, the locking of the switch is possibly not in place, the possibility of locking failure exists, and the isolation knife can be subjected to on-off operation even if the switch is in a closed state. Particularly, the isolation knife is in an open state during maintenance, and the isolation knife can not be switched on absolutely before maintenance is finished, so that an isolation locking device is added.

Furthermore, keep apart limit baffle and seted up and keep apart limit baffle hole, the shutting spacer pin is connected with keeping apart limit baffle hole joint.

Furthermore, the switch body is arranged on the side plate of the isolation frame close to one side of the spacing hole of the side plate of the isolation frame.

Further, the outer diameter of the locking return spring baffle is larger than the inner diameter of the locking guide hole of the side plate of the isolation frame.

Compared with the prior art, the utility model, the beneficial effects include:

1. the utility model has the advantages that the switch body is arranged at the side plate position of the isolation frame, the original locking structure is not changed, the original space is not occupied, and the use of the original locking structure is not influenced;

2. the utility model discloses a shutting direction and shutting spacer pin, after the shutting, can effectively forbid the isolation sword combined floodgate, guarantee the safety in the circuit maintenance.

Detailed Description

It is easily understood that, according to the technical solution of the present invention, a plurality of alternative structural modes and implementation modes can be proposed by those skilled in the art without changing the spirit of the present invention. Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical solutions of the present invention, and should not be considered as limiting or restricting the technical solutions of the present invention in their entirety or in any other way.

An embodiment according to the present invention is shown in conjunction with fig. 1-3. The utility model provides an keep apart blocking device, including switch body 12, install on switch body 12 and close and divide locking lever 1, inside has been seted up spacing hole 3 of isolation frame curb plate and isolation frame curb plate shutting guiding hole 4, 4 internally mounted of isolation frame curb plate shutting guiding hole have rather than swing joint's shutting guiding rod 6, 6 one ends of shutting guiding rod are installed and are connected the shutting spacer pin 7 with the spacing hole 3 cooperation of isolation frame curb plate, shutting reset spring baffle 5 is installed to the other end, shutting guiding rod 6 is close to shutting reset spring baffle 5 one side cover and is equipped with and keeps apart shutting reset spring 11, switch body 12 is close to 7 side-mounting of shutting spacer pin and is kept apart stop collar 10, be fixed with on the isolation stop collar 10 and keep apart limit baffle 9.
