Description
Technical field
The utility model relates to power domains, and in particular to the seal for keeping apart pressurization lead and testing crew.
Background technique
Electric system test insulated pull rod used at present, since the structure of drawhead is simple T shape, structure letter
List has a single function, and testing crew can only be allowed to lift contact test equipment with hand, since testing equipment output test voltage is up to three
Kilovolt is to 100,000 volts, so kept apart pressurization lead and testing crew with insulated pull rod, if insulated pull rod is fallen, pull rod
On band electrical lead will fall therewith, the life of testing crew may be jeopardized, in order to prevent because strong wind or other reasons cause
Insulated pull rod is fallen, so testing crew cannot leave insulated pull rod and do other thing, it is necessary in the case where personnel shortage
There is a testing crew to carry out special act pull rod, wastes human resources, affect test efficiency.
To solve the above-mentioned problems, prior art CN203191407U has devised a kind of dexterous insulated pull rod head, so that
Insulated pull rod head can not have to special testing crew to lift pull rod, and the shape that need to only convert drawhead as needed can expire
Test under the conditions of sufficient Different field.But the drawbar height of this insulation support device is non-adjustable, causes in actual use,
Since lead height mismatches therewith, needs to set plate in the bottom of its draw-bar seat pad or dig pit on the ground, cause to test
It is unable to complete successfully.
Meanwhile the shape for converting drawhead can meet the test under the conditions of Different field.But drawhead is converting
When, it needs to manually boot limiter to complete the adjustment of drawhead, makes to become U-shaped, to hang on the associated components, and due to pull rod
It is used to support lead, therefore its position is higher, and the position that drawhead collapses is also higher, therefore user is in operation limiter
When, needing to step down in stool or setting up double ladder could complete, and use and its inconvenient.
Utility model content
The utility model aim is to provide the seal for keeping apart pressurization lead and testing crew, solve existing
The drawbar height of insulation support device is non-adjustable, causes in actual use, since lead height mismatches therewith, to need at it
