2, the identification piece 5 is arranged on the identification mounting hole 13 and is fixed in a buckling mode, and then the two isolation cover caps 200 are hinged to two side walls of the side cover part 2 of the isolation cover body 100 to form a rotatable and movable structure to keep the opening state.

3, the self-locking element 300 is installed on the isolation cover body 100 and kept in a semi-contact semi-suspension state, and then the first operating rod 501 is operated to enable the first tool head 401 to buckle the top of the self-locking element 300 to a stable state, so that the whole isolation device is lifted to a metal part on the high-voltage side of the transformer and stably put down and buckled into an insulator.

And 4, operating the second operating rod 502, clamping the two isolating covers 200 by using the second tool head 402, closing the two isolating covers 200 towards each other, and operating the second operating rod 502 to withdraw the second tool head 402. Then, the first operating rod 501 is operated to enable the first tool head 401 to withdraw, and then the state is immediately turned into a state of pressing the top of the self-locking piece 300 downwards, so that the self-locking piece 300 moves downwards and forms clamping and locking on the two isolation cover caps 200, and then the whole isolation device is used for completely wrapping and installing the metal part on the high-voltage side of the transformer, and the whole installation process is convenient and rapid without power failure.

It should be noted that the isolating device of the present application does not necessarily need to use the proposed tool, and other alternative tools may be designed according to actual needs.

While the self-locking high-voltage side isolation device and the tool thereof provided by the present application have been described in detail, for those skilled in the art, there are variations in the specific implementation and application scope according to the concepts of the embodiments of the present application.
