Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing, to this reality
It is further elaborated with novel.It should be appreciated that specific embodiment described herein is only to explain the utility model,
It is not used to limit the utility model.
Referring to Fig. 1, a kind of GIS outlet casing tube end shield test measurement tool, including sheet metal 2, the one of the sheet metal 2
End is connected with insulating trip 1, and the other end of the sheet metal 2 is connected with measurement line 3；
Vertical section of the insulating trip 1 with 2 phase of sheet metal from one end is triangle,
Wherein, the vertical section of 1 one end of insulating trip is triangle, i.e. one end of insulating trip 1 is equipped with a tip, is conveniently made
Insulating trip 1 is inserted between bottom shielding of bushing 4 and grounding elastic slice 5.Insulating trip 1 can be such that grounding elastic slice 5 and bottom shielding of bushing 4 is isolated.
One end that the insulating trip 1 is in contact with the sheet metal 2 be equipped with the first groove 101, the sheet metal 2 with it is described
One end that insulating trip 1 is in contact is caught in first groove 101.
Wherein, sheet metal 2 is caught in the first groove 101 of insulating trip 1, then by insulation blanket stud by sheet metal 2 and absolutely
Embolium 1 is fixed, to keep sheet metal 2 and insulating trip 1 stronger.The size of sheet metal 2 can be according to the size of bottom shielding of bushing 4
Customization.
Referring to Fig. 2, the sheet metal 2 includes contact plate 201, the two sides of the contact plate 201 are equipped with baffle 202,
Bottom shielding of bushing 4 can be caught between the contact plate 201 and the baffle 202 of two sides.
The baffle 202 is arc, and the centering angle of two side baffles 202 is towards the contact plate 201.
The two sides of sheet metal 2 are curved baffle, and sheet metal 2 can block bottom shielding of bushing 4, to prevent sheet metal 2 from set
It is slid in pipe end shield 4, reduces the error of test.
Middle part of the sheet metal 2 with 1 phase of insulating trip from one end is equipped with the second groove 203, and the measurement line 3 is placed in
In second groove 203.
