Description
Technical field
The present invention relates to a kind of hanging wire head for Insulation Test standard trolley, belongs to when power application equipment is tested
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 the running status that power equipment need to periodically carry out testing inspection to determine equipment is normal, if exist hiding
Defect exception, when being tested, as 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 is taken high-altitude operation vehicle and reaches experimental test click-through
Row test connection.
(2) test 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 burn 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 above yet suffering from some problems before the hanging wire head of critical component：
1) the standard trolley hanging head for using at present is smooth, cannot crush sometimes conductive surface oxide-film, causes contact not
It is good so that contact resistance is bigger than normal, larger can be caused to the test result of D.C. resistance, loop resistance and chopper time-parameters
Affect.During for carrying out the test of chopper time-parameters, this impact is especially apparent：If desired carry out the time of double-fracture simultaneously
Parameter is tested, then need 6 people while pulling standard trolley, to guarantee that contact is good, can reliably carry out prerun；Otherwise can only be by
One carries out single break prerun, substantially increases the activity duration of field test, affects the job schedule of 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 clipped in test wire (15) on hanging wire head with test wire (15) folder without test wire (15) jack,
Contact resistance is big and very not firm, and test hanging wire can occur often wire clamp and be touched down, and is forced to repeat to put away sports equipment and hanging wire again
Work, affects test efficiency；
4) non-guarantee test line (15) do not slip, and test wire (15) need to knot and tie up on hanging wire head, to test wire (15)
Injury is larger.
The content of the invention
For above-mentioned existing technical problem, the invention provides a kind of contact is good stable, consolidates in process of the test and hang
Line, has a consistent termination on hanging wire head, test wire (15) does not knot the Insulation Test standard trolley hanging wire of the safety and stability not glided
Head, what the present invention was realized in：A kind of Insulation Test standard trolley hanging wire head of safety and stability, including being installed on insulation standard trolley
The hanging head portion (1) of end and hanging head seat (2), hanging head portion (1) are connected and installed on hanging head seat (2) by ring flange, the extension
Test head (3) of the head (1) including an extension, the hook stretched after (4), the upper end of hanging head portion (1) have a plug wire
Hole (5), the front end for testing head (3) are provided with a plush copper (6).
Further, the position that hanging head portion (1) is connected with hanging head seat (2) is passed through by a butterfly bolt (7) and is made
Hanging head portion (1) is flexibly connected with hanging head seat (2), butterfly bolt (7) in the outside of hanging head portion (1) be cased with a roller (8) and
A piece of catch (9), roller (8) are placed in one disk wire casing (10) of formation between hanging head portion (1) and catch (9).
Further, the position that hanging head portion (1) is connected with hanging head seat (2) is the dentation flange (11) for cooperating,
Butterfly bolt (7) is through fixed hanging head portion (1) of dentation flange (11) and hanging head seat (2).
