Realizing a kind of technical scheme of above-mentioned purpose is：A kind of insulating boot for being used to change the one two bar knives, including arrester
Cage, cross-arm cage and arrester isolation plate washer case；
The arrester cage includes cage neck and cage casing, and the cage neck is arranged on the cage
On the left side of casing, the cage neck is trench structure, and the right side and bottom surface of the cage casing are opened wide；
The cross-arm cage is trench structure, is socketed on the inside of the cage neck；
The arrester isolation plate washer housing-case is connected on the outside of the cage casing.
Further, dome-shaped opening is offered on the top surface of the cage casing.
Further, arrester isolation shelves are provided with positioned at the side of dome-shaped opening on the top surface of the cage casing
Plate case slot.
Further, on the surface with the top surface joint of the cage casing of the arrester isolation plate washer case
Offer dome-shaped opening.
Further, the side of the arrester isolation plate washer case is provided with an insulation handle.
Further, one piece of limiting plate is set on the top surface of the cross-arm cage.
A kind of insulating boot for being used to change the one two bar knives of the present utility model, cross-arm cage can be socketed on outside the one two cross-arms
Side, and being adjusted according to the telescopic formula of the one two cross-arms, the whole cross-arm of youngest two is isolated, at the same arrester cage be used for every
From bar knife pile crown, prevent bar knife mutually and terra short from discharging, operating personnel can not be touched different potentials object simultaneously in operation,
The contact between operating personnel and grounding body is avoided, reduces the generation of electric shock accidents rate.

Embodiment
In order to preferably understand the technical solution of the utility model, below by specifically embodiment and combine
Accompanying drawing is described in detail：
Refer to Fig. 1 to Fig. 4, a kind of insulating boot for being used to change the one two bar knives of the present utility model, including arrester every
From cover 1, cross-arm cage 2 and arrester isolation plate washer case 3.
Arrester cage 1 is socketed in outside the one two bar knife lighting arrestor piles.Arrester cage 1 includes cage neck 11
With cage casing 12.Cage neck 11 is arranged on the left side of cage casing 12, and cage neck 11 is trench structure, its
It act as being socketed in the connecting portion of the one two bar knife lighting arrestor piles and the one two cross-arms.The right side and bottom surface of cage casing 12 open
Open, such structure design gives operating personnel's adjustment space, is easy to arrester cage 1 being socketed on the one two bar knives and takes shelter from the thunder
On the outside of device pile crown.Dome-shaped opening is offered on the top surface of cage casing 12, is provided with positioned at the side of dome-shaped opening lightning-arrest
Device isolation plate washer case slot 13.Arrester isolation plate washer case 3 is socketed in the outside of cage casing 12.Arrester isolates plate washer case
Dome-shaped opening is offered on 3 surface with the top surface joint of cage casing 12, a side of dome-shaped opening is inserted
It is connected in arrester isolation plate washer case slot 13, guarantee arrester isolation plate washer case 3 is completely embedded with cage casing 12, no
