Abstract
The utility model discloses a wiring terminal of a current transformer, including a wiring terminal seat connected to a leading-out wire of a secondary winding of the current transformer, wherein the wiring terminal seat includes a terminal seat base, one wiring terminal and a nut, the terminal seat base is provided with a terminal hole, the nut is embedded in the terminal hole, the terminal seat base is provided with the wiring terminal corresponding to the terminal hole, the wiring terminal is used for placing a conductor terminal, the nut is used for pressing the conductor terminal. The wiring terminal of the current transformer also includes a primary wiring terminal of which one end is connected to a primary winding and the other end is provided with a wiring hole. When the current transformer is fixed, the plane, where the wiring hole of the primary wiring terminal is in, is parallel to a horizontal plane, and the terminal hole is a copper terminal hole having a cylindrical shape. The wiring terminal of the current transformer presses the wiring by using the nut in the wiring terminal seat, and the operation is simple and standard. The installation process of the secondary wiring is effectively standardized, and the installation space is increased by changing the position of the primary wiring terminal, thus the primary wiring process is safer.
Description
Technical field
The utility model relates to a kind of current transformer termination, particularly a kind of current transformer once with the secondary connection end device.
Background technology
Existing secondary wiring of current mutual inductor terminal leans on on-the-spot installation personnel scene to do "
" shape installation connection when secondary line is installed; Because personnel's level is inconsistent; Cause installing lack of standardization etc.; And set bolt is shorter and smaller; Not doing circle because of this shape causes wiring lack of standardization; The Bolt-withdrawing device terminal that the lead of being pushed down during wiring is rotated easily produces loosening phenomenon, thereby makes the current transformer outlet be connected with the formation of binding post is insecure; In addition, the binding post of current transformer all exposes in equipment outside, binding post easily and other conductors be connected to form path; Also electric shock accidents can take place easily; The primary connection terminal is dangerous in instrument transformer one side, and the primary connection terminal receives the erecting bed condition restriction when mounted, needs the space bigger; Alleviate labour intensity greatly and improved verification efficient, and can avoid contingency to take place.
Therefore need a kind of wiring that when the current transformer wiring, can be fixed and clamped, safety and termination easily.
The utility model content
In view of this, the utility model technical problem to be solved provides a kind of wiring that when the current transformer wiring, can be fixed and clamped, safety and termination easily.
The utility model is realized through following technical scheme:
The current transformer binding post that the utility model provides comprises terminal block, and said terminal block is connected with the secondary winding lead-out wire of current transformer; Said terminal block comprises terminal base matrix, binding post and nut; Said terminal base matrix offers terminal hole, and embedded nut in the said terminal hole, said terminal base matrix offer and the corresponding binding post of terminal hole; Said binding post is used to place conductor terminal, and said nut is used to compress conductor terminal.
Further, also comprise the primary connection terminal, said primary connection terminal one end is connected with a winding, and the other end is provided with wiring hole, and the plane, wiring hole place of said current transformer primary connection terminal fixedly the time is equal with horizontal plane;
Further, said terminal hole is said copper tip hole;
Further, said copper tip hole is a cylindrical hole;
Further, said terminal hole one side is arranged to the cone inclined-plane;
Further, said primary connection terminal is arranged at current transformer housing centre position.
The beneficial effect of the utility model is: the utility model adopts the nut in the terminal block to compress wiring; Standard simple to operate, effectively standard the installation process of secondary connection, through having changed the position of primary connection terminal; Increase installing space, make that the primary connection process is safer.
