Inconvenient; when replacing the drop-out fuse, there are mainly the following problems: the upper and lower lead wires are not fixed in a suitable position, which may easily cause phase-to-phase short circuit and ground fault; there are no special insulation shielding and isolation measures for the upper and lower lead wires; soft insulation is used for shielding The procedures are complex, and the cross-lapping parts are difficult to grasp and easy to fall off; the current insulating barriers are relatively bulky and lack effective fixing methods, which makes the insulating isolation area of the working area smaller, which affects safety; the labor intensity of the operation Great and long working hours.

Utility model content

The utility model overcomes the deficiencies in the prior art, and the technical problem to be solved is: to provide a simple structure, which can provide a relatively safe insulating working space for operators, and fix the upper and lower leads of the fuse to the Insulated fixtures in place for live replacement of dropout fuses.

In order to solve the above technical problems, the technical solution adopted by the utility model is: an insulating fixing device for live replacement of drop-out fuses, including a fixing pole and two insulating baffles, and the fixing pole is provided with a Fix the entire fixing rod on the mounting arm of the drop-out fuse to be replaced, and the two ends of the fixing rod are respectively provided with the first lead for fixing the upper side and the lower side of the drop-out fuse to be replaced. As for the supporting cross bar and the second supporting cross bar, the two insulating baffles are provided with fixing holes for fixing the insulating baffle on the installation cross arm of the dropout fuse to be replaced.

The insulating baffle includes a first flat plate and a second flat plate, the first flat plate and the second flat plate are arranged perpendicular to each other so that the insulating baffle is L-shaped, and the fixing holes are arranged on the first flat plate; Both sides of the fixing holes are respectively provided with reinforcements; the reinforcements are plate-shaped and made of insulating materials; the insulating baffles are made of epoxy resin; the fixing rods are made of epoxy Made of resin material.

Compared with the prior art, the utility model has the following beneficial effects:

The insulation fixing device in the utility model includes a fixed pole and two insulating baffles, the fixed pole is provided with a fixing piece for fixing the whole fixed pole on the installation cross arm of the drop-out fuse to be replaced, and The two ends of the fixed pole are respectively provided with a first support bar and a second support bar for fixing the upper lead wire and the lower lead wire of the drop-out fuse to be replaced. The plate is fixed to the fixing hole on the installation cross arm of the dropout fuse to be replaced; during operation, fix the fixing pole and two insulating baffles to the installation crossarm of the dropout fuse to be replaced through the fixing piece and the fixing hole respectively In this way, the drop-out fuse to be replaced is located between two insulating baffles, so that the two insulating baffles can effectively insulate and isolate the left and right adjacent charged bodies, so that operators can work safely in a relatively insulated space , to reduce the insulation and shielding of adjacent charged bodies, the use of fixed poles solves the problem of no special fixing devices for the upper and lower drain wires when replacing the fuse, and effectively prevents short circuits between phases, especially when replacing the fuse and post insulators as a whole and ground faults occur.
