Description

Technical Field

[0001] The invention relates to the technical field of drop fuse wire clamps, in particular to a live quick-repair high-voltage drop fuse wire clamp. Background Art

[0002] The function of the high-voltage fuse is to cut off the fault current of the 10kV pole-mounted transformer and protect the transformer. In the years of rural power grid operation experience, the upper retaining spring of the fuse will be loose, the fuse tube will burst, making it impossible to install the upper and lower ends, and the arcing phase short circuit will cause the fuse tube to burn out at the fixing point. There are two main ways to solve this defect: power outage replacement and live work. Power outage replacement usually shuts down the main line where it is located, and replaces the high-voltage fuse after taking safety measures. This method will further expand the scope of the power outage and increase the duration of the power outage; the conditions for live work are not easy to meet: replacing the fuse by live work cannot meet the conditions for live work for the rural power distribution station area due to the small area, weak foundation and inaccessible vehicles.

[0046] An operating rod 2, a connector 3 matched with a connecting block 105 is fixed on the top of the operating rod 2, and a special-shaped groove 4 matched with a limiting rod 106 is formed on the connector 3;

[0047] The insurance component 5 has two ends connected to the corresponding working line clamps 1 through the fixing components 6 respectively.

[0048] A limit slide block 107 is fixed to the side wall of the clamping head 104 , a limit slide groove 108 is provided on the inner wall of the clamping hook 101 , and the limit slide block 107 is slidably installed in the limit slide groove 108 .

[0049] In this embodiment, the operating wire clamp 1 is respectively installed on the power supply side and the load side of the drop-out type fuse, and can connect the power supply side and the load side of the drop-out type fuse after the fuse tube of the drop-out type fuse burns out and falls. The provided clamp hook 101 can be more conveniently hung on the load side of the drop-out type fuse than the original live operating monkey head wire clamp. The operating wire clamp 1 cooperates with the insurance component 5 to ensure the normal operation of the corresponding branch during the replacement of the fuse tube, effectively reducing the power outage time. At the same time, the insurance component 5 is installed between the two operating wire clamps 1 to play the role of insurance of the fuse tube. At the same time, the insurance component 5 can replace different types of high-voltage fuses according to different voltage requirements, and has a wide range of applications. The provided operating rod 2 can facilitate the installation of the operating wire clamp 1 on the power supply side and the load side of the drop-out type fuse, and it can adjust its own length, which is convenient for the staff to adjust according to actual needs.

[0050] Embodiment 2:
