Description
Technical field
The utility model is related to a kind of hanging wire head for Insulation Test standard trolley, belongs to power application equipment and is tested
When work high above the ground testing equipment field, the Insulation Test standard trolley hanging wire head of specially a kind of safety and stability.
Background technology
Whether power equipment need to periodically carry out testing inspection normal to determine the running status of equipment, if exist hiding
Defect exception, when being tested, because the experimental test point of high-grade voltage electricity equipment is generally up to nearly 10 meters apart from ground,
Very big difficulty is caused to test connection.Conventional two methods carry out such wiring at present：
(1) high-altitude wiring is carried out using high-altitude operation vehicle, testing crew takes high-altitude operation vehicle and reaches experimental test click-through
Row test connection.
(2) experiment hanging wire is carried out with telescopic insulation standard trolley.
High-altitude wiring is carried out using high-altitude operation vehicle with high costs, and work high above the ground risk is larger, generally, in height
If place, personnel are nearer apart from charging equipment, it is easier to which sensing electric injury or direct electric shock occur.High-altitude operation vehicle will complete to set
The wiring of standby three-phase needs continuous shift position, causes wiring inefficiency.
It is advantageous from from the point of view of safety, efficiency, cost using scalable insulation standard trolley, but as insulation standard trolley
Using some problems are above still present before the hanging wire head of critical component：
1) the standard trolley hanging head for using at present is smooth, and conductive surface oxide-film cannot be crushed sometimes, causes contact not
Good so that contact resistance is bigger than normal, the test result to D.C. resistance, loop resistance and breaker time-parameters can cause larger
Influence.When being tested for carrying out breaker time-parameters, this influence is especially apparent：If desired the time of double-fracture is carried out simultaneously
Parameter is tested, then need 6 people while pulling standard trolley, to ensure that contact is good, can reliably carry out prerun；Otherwise can only be by
One carries out single break prerun, substantially increases the job schedule of the activity duration of field test, influence maintenance and prerun；
2) carrying out CVT, test of lightning arrester need to be when equipment respectively saves hanging wire on flange, and hanging wire head cannot firmly catch on flange
, easily there is bar in bolt, and the operation to scene adds many security risk hidden danger；
3) hanging wire head can only be pressed from both sides with test wire (15) and test wire (15) is clipped on hanging wire head without test wire (15) jack,
Contact resistance is big and very not firm, and experiment hanging wire can occur wire clamp and be touched down often, is forced to repeat to put away sports equipment and hanging wire again
Work, influences test efficiency；
4) non-guarantee test line (15) does not slip, and test wire (15) need to knot and tie up on hanging wire head, to test wire (15)
Injury is larger.
