Reference numeral:
10, fixed wiring part; 11, the first movable part; 12, the second movable part; 13, holding tank; 20, wiring wire; 21, web joint; 40, web member.
Embodiment
Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
As shown in Figure 1, according to embodiments of the invention, this termination comprises fixed wiring part 10 and wiring wire 20.Fixed wiring part 10 comprises the first movable part 11 and forms the clamping space that wiring thing is treated in clamping between the second movable part 12, first movable part and the second movable part; The first end of wiring wire 20 is detachable, and is connected in fixed wiring part; Second end of wiring wire 20 is connected to the connection joint of testing equipment.
Apply this termination, testing crew, when carrying out error test to current transformer, both can once complete joint test circuit quickly and easily, can also realize circulation and connect; Solve not for the problem of the Special wiring device of contact type high-tension current inductor error test, and, this termination makes the process of wiring more simple and efficient, saves the setting up time of test, improves the order of accuarcy of current transformer error test.
Particularly, in embodiments of the invention, termination also comprises web member 40.Web member 40 is connected between the first movable part 11 and the second movable part 12, web member 40 make the first movable part 11 and the second movable part 12 hinged.First movable part 11 and the second movable part 12 can rotate around web member 40, when wiring thing is treated in fixed wiring part 10 clamping, operating personnel can operate the first movable part 11 and the second movable part 12 neatly, the clamping space of wiring thing expands first to make clamping treat, then fixed wiring part 10 being connected to treats on wiring thing, hand is decontroled by operating personnel, and clamping space folds, and makes to treat that wiring thing is clamped in and adds in space.Like this, operating personnel just can complete the wiring work before to current transformer error test smoothly.
Preferably, wiring wire 20 is brass wire.Conveniently brass wire is arranged on the first movable part 11 or the second movable part 12 by staff, the first end of brass wire is provided with web joint 21, web joint 21 offers through hole, web joint 21 is located in the threaded post of the first movable part 11 or the second movable part 12 by through hole by staff, then utilizes the set nut be set in threaded post to be locked by web joint 21.
Be provided with elastic component between first movable part 11 and the second movable part 12, elastic component makes the first movable part 11 and the second movable part 12 be in clamped condition all the time under not by the effect of external force.Preferably, elastic component is spring.
First movable part 11 and the second movable part 12 are combined to form clamp, fixed wiring part 10 is treated wiring thing in the mode of clamp and is carried out clamping connection, both connection when current transformer error test had been facilitated, this termination can also be recycled, decrease the use of disposable wiring connector, save the use amount of disposable test tool.In time treating that wiring thing is column binding post, in order to adapt to clamp this binding post better, the jaw place of clamp is provided with holding tank 13, make holding tank 13 better with the surface contact of binding post, contact is good, decrease termination and contact resistance when being connected between wiring thing, thus it is more accurate that current transformer error is tested.
Particularly, grip finger with treat the clamping surface that wiring thing contacts is provided with stripe shape groove, stripe shape groove is evenly and arrange abreast.The setting of stripe shape groove also makes the higher with the friction factor of the clamping surface of thing to be contacted of jaw, and at termination with when being connected until wiring thing, termination, not easily from treating that wiring thing departs from, ensures carrying out smoothly of current transformer error test.
Owing to needing to pass to electric current when carrying out the error testing of current transformer, like this when staff uses termination to connect current transformer, may electric shock accidents be there is, there is the threat of the life security to staff.In order to reduce the Danger Electric shock risk of staff when using termination connecting circuit, one end away from jaw (namely staff grasps the operating side that clamp expands to manipulate clamp or folds) of clamp is enclosed with insulated hull.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
1, can once complete joint test circuit quickly and easily, circulation can also be realized and connect; Solve not for the problem of the Special wiring device of contact type high-tension current inductor error test, and, this termination makes the process of wiring more simple and efficient, saves the setting up time of test, improves the order of accuarcy of current transformer error test.
2, current transformer error is made to test more accurate.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
