One end of the steel-pin joint is connected with a test insulator and the other end is connected with a binding post. The binding post is connected with a high-voltage insulation wire. By adopting the above technology provided by the utility model, the steel-pin joint is connected with the test insulator and the binding post and a hole is built in the binding post. A copper core of the high voltage line penetrates in the hole and is fixed in the hole by utilizing a screw, so that corrosion resistance and stability of the copper core are guaranteed. One end of the steel-pin joint imitates a structure of an insulator steel cap and the steel pin of the test insulator can be completely wrapped, so that an area requirement of insulator contact is satisfied. In order to matching with different diameter of the steel pins of different insulators, different sizes of sleeve hoops are configured on the joint and can be replaced when different tests are carried out, so that operation is convenient and the connection device is suitable for large-scale production application.
Description
Technical field
The utility model belongs to Voltage for Insulators on HV Lines performance detection apparatus technical field, is specifically related to the coupling arrangement of a kind of effectively connecting insulator steel pin and hi-line.
Background technology
At present in about the test that detects Insulators Used, the steel pin connected mode of hi-line and insulator mainly contains two kinds: 1) copper cash wound form, the method is the copper core in the hi-line to be cut stay length, then the steel pin of insulator firmly twines the 3-5 circle, the method can guarantee that hi-line fully contacts with the steel pin of insulator, guarantee to gather the stability of electric current, but need repeat to bend the inner core of hi-line, cause easily metal fatigue to cause the copper cash fracture, and because test is to carry out in moist hyperbaric environment, accelerated the electrocorrosion of copper core, operation repeatedly can make afterwards to be exposed to and get the corrosion of hi-line copper core in the air, brings potential safety hazard; 2) clamping type, the inner core of hi-line is placed the sleeve of crocodile clip, the corrosion of copper core can be effectively prevented, simultaneously, the steel pin place of insulator can be directly dop directly be fixed on, simple to operate, but the steel pin diameter of different insulators is not identical, and too small crocodile clip can not be fixed with large insulator, when too large crocodile clip cooperates with pony insulator, can because surface of contact is narrower, cause current acquisition unstable.
The utility model content
For the above-mentioned technology that exists in the prior art, the purpose of this utility model is to provide the coupling arrangement of a kind of effectively connecting insulator steel pin and hi-line.
The coupling arrangement of described a kind of electric insulator steel foot and hi-line is characterized in that comprising steel pin connector, and described steel pin connects first end and is connected with insulator with test, and the other end is connected with binding post, and described binding post is connected with high voltage insulated cable.
The coupling arrangement of described a kind of electric insulator steel foot and hi-line is characterized in that described steel pin connector termination arranges chapeau de fer, and described test insulator bottom arranges and cooperates the steel pin that is connected with the chapeau de fer socket.
The coupling arrangement of described a kind of electric insulator steel foot and hi-line is characterized in that described binding post inside is equipped with built-in hole, and the copper core of high voltage insulated cable penetrates in the built-in hole and is connected with binding post, and is fixed by screw.
Above-mentioned a kind of electric insulator steel foot and the coupling arrangement of hi-line comprise steel pin connector, and described steel pin connects first end and is connected with insulator with test, and the other end is connected with binding post, and described binding post is connected with high voltage insulated cable.The utility model is by adopting above-mentioned technology, by steel pin connector joint test with exhausted son and binding post, built-in hole is set in binding post, allow the copper core of hi-line penetrate, utilize simultaneously screw that the copper core is fixed in the hole, guaranteed the anticorrosive and stable of copper core, and the steel pin is connected the structure of the imitated insulator steel cap of first end, can wrap the exposed copper core of hi-line fully, prevent the cargo sweat that is subjected to of copper core, can guarantee at least two hundred tests, copper core non-corrosive, the electric insulator steel foot of the cuff of the different size of steel pin connector lug configuration between can supporting diameter 20mm-35mm, can wrap simultaneously the surface of electric insulator steel foot 3/4, contact area satisfies the current acquisition requirement, can change when carrying out different tests, make things convenient for operation, be suitable for large-scale production and application.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: insulator is used in the 1-test, 2-steel pin connector, and the 3-binding post connects, the 4-high voltage insulated cable.
Embodiment
The utility model will be further described below in conjunction with Figure of description:
As shown in Figure 1, the coupling arrangement of a kind of electric insulator steel foot and hi-line carries out required steady current collection signal for test and creates conditions.It comprises steel pin connector 2, described steel pin connector 2 one ends are connected with insulator 1 with test, the other end is connected with binding post 3, described binding post 3 is connected with high voltage insulated cable 4, steel pin connector 2 terminations arrange chapeau de fer, and described test insulator 1 bottom arranges and cooperates the steel pin that is connected with the chapeau de fer socket; Binding post 3 inside are equipped with built-in hole, and the copper core of high voltage insulated cable 4 penetrates in the built-in hole and is tightly connected with binding post 3, and is fixed by screw, reach moistureproof antirust effect, make hi-line in the test of long duration process, keep clean state, the current spikes of experiment test is reduced, stable.
The utility model is by adopting above-mentioned technology, use absolutely and binding post by steel pin connector joint test, built-in hole is set in binding post, allow the copper core of hi-line penetrate, utilize simultaneously screw that the copper core is fixed in the hole, guaranteed the anticorrosive and stable of copper core, and the steel pin is connected the structure of the imitated insulator steel cap of first end, can wrap test fully with the steel pin of insulator, be satisfied with the area requirements that insulator contacts, in order to cooperate the difference of the sub-steel pin of different insulative diameter, connector position has disposed the cuff of different size, can when carrying out different tests, change, make things convenient for operation, be suitable for large-scale production and application.
