In order to realize the purpose, the utility model discloses a technical scheme is:

the utility model provides a high tension fuse convenient to change fuse-link, includes fuse porcelain sleeve and support knob insulator, the quantity that supports the knob insulator is two, supports the knob insulator symmetry and sets up at fuse porcelain sleeve's both ends, and fuse porcelain sleeve's both ends can be dismantled and be connected with the wiring end cap, and fuse porcelain sleeve's inside is provided with the fuse-link, and the outside of fuse-link is provided with rain-proof cover, and the both ends of fuse-link are provided with the connecting wire, and the connecting wire passes through wiring end cap connecting circuit.

And the wiring end cap is fixedly connected with a spring.

The top of supporting the knob insulator is provided with the link, and the wire outgoing slot has been seted up to one side of link, supports the knob insulator and passes through the link and connect fuse porcelain bushing.

And a sealing gasket is arranged on the fuse porcelain sleeve.

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

the utility model discloses a change the outward appearance form of device, the staff can use and change the pole, take the device ground and change the fuse-link, convert high altitude construction to the ground operation, the change of form makes the work step reduce, the work that makes two at least people cooperate to accomplish becomes alone can independently accomplish the operation, the human cost has been reduced, the activity duration has been reduced simultaneously, become live working with the outage operation simultaneously, the process of having saved the power failure and reporting to the police is facilitated, for the operation personnel, the security of operation is improved.
