Abstract
The utility model relates to a primary wiring terminal of a current transformer. The shaped of the primary wiring terminal is U-shaped or L-shaped, a hole is formed in the primary wiring terminal, one end of the primary wiring terminal is connected with a transformer, and the other end of the primary wiring terminal is connected with a busbar in a lap joint mode. The hole, the size and the shape of the primary wiring terminal can be designed according to actual needs, installation is convenient, and the condition that due to the fact that a wiring manner or the hole distance of the terminal is different, the transformer or an primary busbar must changing is avoided.
Description
Technical field
The utility model belongs to the current transformer technical field, particularly relates to a kind of primary connection terminal of current transformer.
Background technology
The primary connection terminal of support type current transformer becomes 2 holes or 4 holes according to the size design of rated primary current, is suitable for during with the instrument transformer overlap joint for busbar.Generally, during rated primary current≤1250A, a terminal of current transformer is 2 holes; During rated primary current>1250A, a terminal of current transformer is 4 holes.In addition, a terminal of pouring current transformer is cast on instrument transformer, can't carry out the secondary change.
Present primary connection terminal inevitably will be adjusted product terminal sizes or connected mode if occur because link up deficiency or user early stage when changing the busbar shiplap joint mode temporarily in actual use.And this is impossible change for a finished product instrument transformer, causes thus can not using or customized new product again of product, very large waste beyond doubt.
Need owing to changing instrument transformer or wiring, the hole count of a busbar design be not inconsistent with a terminal hole count of instrument transformer or the faying surface of plane, terminal place and busbar not at same plane, this installation to instrument transformer also brings a lot of inconvenience.
Summary of the invention
The utility model provides a kind of and avoids because of the mode of connection or terminal hole apart from the different primary connection terminals that must change the current transformer of instrument transformers or a busbar for solving the technical problem that exists in known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of primary connection terminal of current transformer, " U " type that is shaped as of this primary connection terminal or " L " type, arrange porosely on it, the one end is connected with instrument transformer, the other end and busbar overlap joint.
Advantage and the good effect that the utlity model has are:
In the utility model, hole, size, shape can be according to the designs of actual installation needs, and convenient the installation avoided because of the mode of connection or terminal hole apart from the different situations that must change instrument transformers or a busbar.

Fig. 2 is Fig. 1 end view;
Fig. 3 is Fig. 1 vertical view;
Fig. 4 is L-type primary connection terminal structure front view;
Fig. 5 is Fig. 4 end view;

Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See also Fig. 1~Fig. 6, a kind of primary connection terminal of current transformer, " U " type that is shaped as of this primary connection terminal or " L " type arrange porosely on it, and the one end is connected with instrument transformer, the other end and busbar overlap joint.When terminal hole count of instrument transformer and busbar hole count are not inconsistent, can use Fig. 1~" U " type terminal shown in Figure 3; Terminal of instrument transformer and busbar hole count are not inconsistent, and not when same plane, can use Fig. 4~" L " type terminal shown in Figure 6.
During actual installation, hole count is not inconsistent sometimes, and sometimes not at same plane, size is different sometimes, is multiple in above situation sometimes, so can design the binding post of different size, different hole counts according to installation requirements, needn't change instrument transformer or a busbar.
Claims (1)
1. the primary connection terminal of a current transformer, is characterized in that, " U " type that is shaped as of this primary connection terminal or " L " type arrange porosely on it, and the one end is connected with instrument transformer, the other end and busbar overlap joint.
