Specific embodiment：
In order that technological means, creation characteristic, reached purpose and effect that the present invention realizes are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
Insulated target Insulation Test complexes as shown in Figure 1, Figure 2, Figure 3 and Figure 4, mainly include bracing frame, insulating bar,
Conducting rod, conduction brush, around cloth disk etc. five part composition.Bracing frame acts primarily as the effect of supports insulative bar, and bracing frame is by supporting leg
1st, fixing support arm 2, active supporting arm 3, limiting plate 4, locking bar 5, spring 6, position blocking pin 7, rotating shaft 8 and supporting mouth 9 form.Insulation
Bar 10 penetrates in conducting rod 11, acts the effect supporting conducting rod 11, and conducting rod 11 can be freely rotatable on insulating bar 10.Lead
11 points of more pieces of electric pole are constituted, and conducting rod 11 first segment head end has a groove 12, and there is outer terraced interface 13 first segment end, and remaining is every
There are interior terraced interface 14 and outer terraced interface 13 in the head end of section and end, respectively can closely be connected between envoy and section, to connect
Touch reliable.Conduction is brushed with a retainer ring 15 and three brushing pieces 16, and retainer ring 15 is fixed on insulating bar, and brushing piece 16 is placed in conduction
In groove 12, three brushing pieces can ensure that the contact that conduction brush is with conducting rod is reliable, reduces contact resistance.Around cloth disk by support bar
17 are constituted with insulation circular discs 18, the flexible jaws 19 of circular discs 18, and support bar is used for fixing circular discs, and circular discs are used for being wound around
Insulated target, resilient clip opening is used for fixed insulation blanket side.Support arm is used for supports insulative bar, and the supporting mouth 9 on bracing frame is used for propping up
Around the support bar 17 of cloth disk, limiting plate 4 is used for limiting the activity point of view of active supporting arm 3, locking bar 5 and 7 fixations of position blocking pin for support
The effect of active supporting arm 3 maximum angle.Spring 6 makes active supporting arm under force, can be in the range of certain angle
Rotate.
In the case of normality, when not tested, position blocking pin 7 is in retracted mode, then locking bar 5 is not stuck, activity
It is close to fixing support arm 2 direction that support arm 3 follows rotating shaft 8 under the natural elasticity effect of spring 6.Meanwhile, insulating bar 10, lead
Electric pole 11 and all can taking off from bracing frame around cloth disk support bar 17.
When needing insulated target is tested, active supporting arm is first made to overcome elastic force to draw to deviating from fixing support arm direction
Open about 30 degree, the angle that gag lever post 4 can limit active supporting arm will not be pulled open too greatly, and now, extracting position blocking pin 7 makes it block work
Locking bar 5 on dynamic support arm, make active supporting arm keep certain angle and static.Conducting rod 11 is often saved docking firmly again, so
Afterwards insulating bar 10 is inserted in conducting rod 11, and the brushing piece 16 of conduction brush is snapped onto in conductive groove 12, keep contact good,
Two groups altogether.Finally this two groups are connected the bayonet socket that intact insulating bar is coupled with fixing support arm 2 and active supporting arm 3
Interior.Clamp one side of insulated target afterwards with the resilient clip opening 19 around cloth disk, and insulated target is wrapped in circular discs 18, then will
Its support bar 17 snaps onto in the supporting mouth 9 of bracing frame, then the another side of insulated target is put into active supporting arm and fixing
Between the conducting rod 11 of brace, and make each side of insulated target beyond the distance of conducting rod 11 about 150mm.Now, position blocking pin 7 is made to contract
Return, locking bar 5 is not stuck, active supporting arm 3 then follows rotating shaft 8 to fixing support arm 2 side under the effect of the natural elasticity of spring 6
To rotation, active supporting arm is made to clamp insulated target with the conducting rod on fixing support arm.Finally by the terminal of Insulation Test instrument
It is clipped in conduction brush.In process of the test, pull insulated target just can be rapidly performed by Insulation test by slow, and can accurate,
Timely find insulation defect position.Because conducting rod can rotate, therefore, any damage will not be produced to insulated target.
General principle, principal character and the advantages of the present invention of the present invention have been shown and described above.The technology of the industry
, it should be appreciated that the present invention is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification is originally for personnel
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes
Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and its
Equivalent thereof.
