Description

Jointing clamp for auxiliary maintenance of relay protection of transformer substation

Technical Field

The utility model relates to an overhaul the apparatus, specifically the supplementary binding clip that overhauls of transformer substation's relay protection.

Background

When the electric instrument is adopted for relay protection detection of a transformer substation, the common jointing clamp clamps the metal rod of the insulating binding post, so that the circuit of the common jointing clamp is conducted and then line detection is carried out through various instruments. As shown in the attached figure 5 of the specification, a common clamping mode of the jointing clamp is adopted, because the diameter of the insulated binding post is larger than that of the metal rod, the jointing clamp must be clamped from the side surface to effectively clamp the metal rod, and because the space between the adjacent insulated binding posts is small when the jointing clamp is clamped from the side surface, the jointing clamp is labor-consuming and time-consuming in the operation process, and the overhauling efficiency is reduced. Therefore, I design a simple auxiliary tool which can be mechanically applied to the jointing clamp to solve the defects.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a transformer substation relay protection is supplementary to be overhauld and is used binding clip, it need not be hard again consuming time use binding clip edgewise carry out the centre gripping, has avoided the less centre gripping operation degree of difficulty that brings in space between the adjacent insulating terminal.

The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:

the jointing clamp for the auxiliary overhaul of the relay protection of the transformer substation comprises a jointing clamp body, wherein a connecting plate is arranged on a top clamping jaw of the jointing clamp body, the distance between the tail end of the connecting plate and the tail end of the top clamping jaw is 5-10 mm, and a conductive part is arranged at the tail end of the connecting plate; after the jointing clamp body is clamped on the insulating binding post, the conductive part is contacted with the metal rod of the insulating binding post.

The conductive part is a plurality of bundles of metal copper wires.

The conductive component is an elastic metal copper sheet.

And the elastic metal copper sheet is provided with a semicircular groove matched with the metal rod of the insulating binding post.

Contrast prior art, the beneficial effects of the utility model reside in that:

set up the connecting plate on the top clamping jaw of binding clip body, the connecting plate end sets up electrically conductive parts, and the binding clip can openly clip insulating terminal from insulating terminal lateral translation back, and electrically conductive parts just can realize the circuit from the metal pole contact of lateral direction and insulating terminal at this moment. By the method, the wiring clamp does not need to be used for clamping from the side surface in a time-consuming manner, and the clamping operation difficulty caused by the small space between the adjacent insulating wiring terminals is avoided.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

Example 1:

the utility model relates to a wiring clamp for auxiliary overhaul of transformer substation relay protection, the main structure of which comprises a wiring clamp body 1, a connecting plate 3 is arranged on a top clamping jaw 2 of the wiring clamp body 1, the distance between the end of the connecting plate 3 and the end of the top clamping jaw 2 is 5 mm-10 mm, and a conductive part 4 is arranged at the end of the connecting plate 3; the distance of 5 mm-10 mm can ensure that when the jointing clamp laterally translates from the insulating binding post 8 and then clamps the insulating binding post 8 from the front, the conductive part 4 can ensure that the metal rod 9 of the insulating binding post 8 is contacted from the lateral direction to realize circuit conduction.

The conductive member 4 is a bundle of metallic copper wires 5. Multi-beam metal copper wire 5 has good bending deformation ability, can be to multi-beam metal copper wire 5 appropriate to being close to insulating terminal 8 one side crooked to when fine assurance binding clip openly cliied insulating terminal 8 after 8 lateral translation from insulating terminal, conductive parts 4 can guarantee to realize that the circuit switches on from the side direction with the contact of metal pole 9 of insulating terminal 8. And one metal copper wire in the multiple bundles of metal copper wires 5 contacts with the metal rod 9 of the insulating binding post 8 to realize circuit conduction, and the metal copper wire is cheap and easy to obtain and can be used as a daily waste metal copper wire.
