6th kind of technical scheme of the utility model current transformer be：At the 5th kind of the utility model current transformer
On the basis of technical scheme, the closure cover plate circumference is provided with rounding.
To achieve the above object, the first technical scheme of the utility model closure cover plate is：One kind closure cover plate, it is described
Closure cover plate is provided with wears round and the attachment structure for being connected with bus casing for bus-bar plug.
The utility model closure cover plate second of technical scheme be：In the first technology of the utility model closure cover plate
On the basis of scheme, the attachment structure includes the mounting hole on closure cover plate and the spiral shell for being connected with mounting hole
Bolt.
The utility model closure cover plate the third technical scheme be：In second of technology of the utility model closure cover plate
On the basis of scheme, the mounting hole is slotted hole.
The utility model closure cover plate the 4th kind of technical scheme be：The utility model closure cover plate the first to the
On the basis of three kinds of any one technical schemes, the closure cover plate circumference is provided with rounding.
The beneficial effects of the utility model are：Round of wearing on closure cover plate is easy to the interspersed of bus-bar, closure cover plate with
Current transformer end coordinates, and dust and moisture is not easily passed through in end position access switch cabinet, meets the anti-of switch cubicle
Grade is protected, ensure that the safe operation of power network.
Further, mounting hole is slotted hole, avoids transformer end silk hole from mounting hole deviations being present and unfavorable
Occur in the situation that closure cover plate is fixed.
Further, the size for wearing round determines according to the size of bus-bar, it is ensured that bus-bar is just by wearing
Round without there is too wide arc gap in-between, to meet the degree of protection of switch cubicle.
Further, the end of current transformer is provided with silk hole, is easy to current transformer end to pass through spiral shell with closure cover plate
Tether and connect.
