Abstract

The invention discloses a kind of CT, PT secondary short circuit line, comprise first, second, and third clip linked together, described three clips include the first intermediate plate and the second intermediate plate that are connected by clip jack-post, form bite when the first intermediate plate and the second intermediate plate front end bite, in the middle of when bite closes, form a groove; First intermediate plate one end of described first clamp, with insulating case, the second intermediate plate is connected with the link of exterior insulation, inner conductive; First intermediate plate of described second clamp is connected with wire, and the other end of wire is provided with top with the conduction splicing ear of conducting terminal afterbody with conductive jack; Three clip second clamping piece structures are identical, and the 3rd clip is identical with second clamp structure; The conducting terminal of second clamp inserts the link of first clamp, and the conducting terminal of the 3rd clip inserts the conductive jack formation current path of second clamp.This CT, PT secondary short circuit line can form reliable short circuit, simplify the operation, and effectively ensures operating personnel's personal safety.

Description

CT, PT secondary short circuit line
Technical field
The present invention relates to a kind of electric power system common tool, be specifically related to a kind of CT, PT secondary short circuit line.
Background technology
Daily electric power system usually uses a plain conductor or screwdriver to add nuditing wire to current transformer (CT), voltage transformer (PT) and operates when carrying out secondary short circuit, namely can not form reliable short circuit, also there is potential safety hazard.When particularly verifying in controller switching equipment commissioning test work that protection coil carries out resistance measurement absolutely to metering coil and measuring coil, because CT, PT secondary coil distance is near, winding space is little, not only operates inconvenience, be also easy to injure the operating personnel personnel that cause.
Summary of the invention
Forming reliable short circuit when carrying out secondary short circuit to make CT, PT, simplifying the operation, and effectively ensure the personal safety of operating personnel, the invention provides a kind of CT, PT secondary short circuit line, can solve the problems of the technologies described above, its concrete technical scheme is as follows:
A kind of CT, PT secondary short circuit line, comprise the first ~ three clip linked together, described three clips include the first intermediate plate and the second intermediate plate that are connected by clip jack-post, the front portion of described first intermediate plate and the second intermediate plate is interlocked formation bite, a groove is formed in the middle of described bite, the shape of this groove and binding post mating shapes, be conducive to the bond strength of reinforcing shorting stub and binding post; First intermediate plate of described first clamp is away from bite one end with insulating case, and the second intermediate plate of described first clamp is connected with link away from bite one end, described link exterior insulation, inner conductive; First intermediate plate of described second clamp is connected with wire, and the other end of described wire is provided with conduction splicing ear, and described conduction splicing ear top is provided with conducting terminal, afterbody is provided with conductive jack; Second intermediate plate of described second clamp is identical with the second clamping piece structure of first clamp; Described 3rd clip is identical with second clamp structure; The conducting terminal of described second clamp inserts the link of first clamp, and the conducting terminal of described 3rd clip inserts the conductive jack formation current path of second clamp.
The contact-making surface of the bite of described three clips is zigzag.
This CT, PT secondary short circuit line is connected with binding post closely, can form reliable short circuit, easy and simple to handle, effectively ensure that the personal safety of operating personnel.
Accompanying drawing explanation
Fig. 1 is CT, PT secondary short circuit toe-in composition of the present invention;
Fig. 2 is the second clamp structure chart of CT, PT secondary short circuit line of the present invention.
Embodiment
Be described in detail below in conjunction with the structure of the drawings and specific embodiments to CT, PT secondary short circuit line of the present invention.
As shown in Figure 1, 2, a kind of CT, PT secondary short circuit line, comprise the first ~ three clip 1,5,6 linked together, described three clips 1,5,6 include the first intermediate plate and the second intermediate plate that are connected by clip jack-post, the front portion of described first intermediate plate and the second intermediate plate is interlocked formation bite, form a groove 2 in the middle of described bite, the shape of this groove 2 and binding post mating shapes, be conducive to the bond strength of reinforcing shorting stub and binding post; On first intermediate plate of described first clamp 1 away from bite one end with insulating case 3, the second intermediate plate of described first clamp 1 is connected with link 10 away from bite one end, described link 10 exterior insulation, inner conductive; First intermediate plate of described second clamp 5 is connected with wire 4, and the other end of described wire 4 is provided with conduction splicing ear 7, and described conduction splicing ear 7 top is provided with conducting terminal 9, afterbody is provided with conductive jack 8; Second intermediate plate of described second clamp 5 is identical with the second clamping piece structure of first clamp 1; Described 3rd clip 6 is identical with second clamp 5 structure; The conducting terminal 9 of described second clamp 5 inserts the link of first clamp 1, and the conductive jack 8 that the conducting terminal 9 of described 3rd clip 6 inserts second clamp 5 forms current path.
The contact-making surface of the bite of described three clips 1,5,6 is zigzag.
During use, second clamp 5, the 3rd clip 6 are connected with equipment binding post respectively, first clamp 1 is connected with earth connection, and this CT, PT secondary short circuit line is connected with binding post closely, and ground connection is reliable, effectively ensure that the personal safety of operating personnel.
