Abstract
The utility model discloses a multi-purpose CT secondary short-circuited terminal, comprising at least one terminal body. The terminal body is provided with at least two test holes, and the head end of the terminal body is provided with a card head. The tail end of the terminal body is provided with a card slot, and the card head and the card slot connected between the terminal bodies can be combined end to end. The multi-purpose CT secondary short-circuited terminal is a single combined-type structure. Each terminal body is provided with a plurality of test holes, and standard test lines can be inserted into the test holes. The adjacent terminal bodies can be combined end to end to form a new CT short-circuited terminal according to the needs, and various specifications of short-circuited pieces are not carried. The multi-purpose CT secondary short-circuited terminal has the advantages of skillful structure, convenient carrying and wide range of application.
Description
Technical field:
The utility model relates to the current transformer in the electric power system, particularly short circuit Current Transformer Secondary terminal used tool.
Background technology:
Short circuit CT is the action that often runs in two tasks, existing C T short circuit has 2 kinds of forms in flakes: one is that four short circuit terminals connect together into as a whole, this structure short circuit speed is fast, carry easily, but can only short circuit adjacent CT terminal and have only four terminals, whether normal, and lose easily if being not easy to detect the CT loop during recovery; Two is four short circuit terminals connects together by the flexible cord welding, and this structure can the non-conterminous CT terminal of short circuit, but flexible cord fractures easily, and is difficult for finding that can cause the CT second open circuit, damage equipment also is not easy to carry.
The utility model content:
Technical problem to be solved in the utility model provides a kind of multipurpose CT secondary short circuit terminal at above deficiency exactly, the line that this short circuit terminal can arbitrarily increase between terminal number and the terminal can shorten or prolong the use of convenient on-the-spot various situations again as required in certain-length.
Technical solution adopted in the utility model is:
A kind of multipurpose CT secondary short circuit terminal includes at least one terminal body, and terminal body is provided with at least two instrument connections, and the head end of terminal body has dop, and the tail end of terminal body has draw-in groove.
Dop between the terminals of adjacent body and draw-in groove can be combined into the sub-body of multiterminal from beginning to end and carry out short circuit.
Have corresponding connecting hole on dop and the draw-in groove, can carry out cross-under by bolt.
Terminal body is an electric conductor.
The utility model is single combined structure, each terminal body is provided with some instrument connections, can insert the standard testing line, can constitute new CT short circuit terminal as required from beginning to end again between the terminals of adjacent body, and the short circuit that does not need to carry many specifications in flakes, structure is ingenious, and is easy to carry, applied widely.
Description of drawings:
Fig. 1 is the single terminal main body structure of a utility model profile.
Fig. 2 is the structural representation of embodiment.
Embodiment:
The utility model will be further described below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2, this multipurpose CT secondary short circuit terminal includes two terminal body 1, terminal body 1 adopts metallic copper to make, and conducts electricity very well, and each terminal body 1 is provided with four instrument connections 2, can insert the standard testing line in the instrument connection 2, the head end of terminal body 1 has dop 3, and tail end has draw-in groove 4, has corresponding connecting hole 5 on dop 3 and the draw-in groove 4, by bolt 6 the 1 head and the tail cross-under of two terminal body is constituted an integral body together, and then carry out short circuit according to need of work.
