Abstract
The utility model relates to a current transformer. A secondary side link group of an existing current transformer is fixed at the lower part of a mutual transformer, so the operation is inconvenient. The utility model comprises a transformer main body (8), and a secondary side link group (4), wherein, the transformer main body (8) is composed of an inductive iron core, and a secondary side coil which is provided with an insulation protecting layer; the secondary side coil is wound on the inductive iron core. The utility model is characterized in that the secondary side link group (4) is fixed at the upper top end of the mutual transformer main body (8); a primary side thread does not need passing when the utility model cleared and wired; the installation, the maintenance and the operation are convenient.
Description
The utility model belongs to a kind of current transformer.
Current transformer is the big electric current that flows through according to primary side, induces the little electric current of certain ratio at secondary side, for measuring or a kind of electric device of used for relay protection.Its main body is the secondary coil of the certain number of turn of coiling on inductive iron core, and the coil outside is cast with insulating protective layer, and the two ends of coil is welded in the secondary side wiring group respectively and is positioned on the position of current transformer body insulating protective layer pour mass.The secondary side wiring group of original current transformer all is fixed on the current transformer body bottom, promptly in base end, tears open, must walk around the primary side threading during wiring, and the primary side threading adopts busbar usually, the cross section broad blocks secondary side wiring group position, so it is very inconvenient to carry out installation and maintenance when operation.
The utility model aim to provide a kind of maintenance is installed and tear open, current transformer that wiring is easy to operate.
The technical scheme that realizes above-mentioned purpose is (referring to implementing illustration): this current transformer comprises that it is characterized in that: described secondary side wiring group (4) is fixed on the last top of current transformer body (8) by inductive iron core and coiling current transformer body (8), the secondary side wiring group (4) formed of the second siding ring of tape insulation protective layer thereon.
Secondary side wiring group of the present utility model is fixed on the top of current transformer body, tears open, wiring needn't walk around the primary side threading, and operation was more convenient when maintenance was installed.

Embodiment 1 explanation:
This routine current transformer body 8 is made up of toroidal inductive iron core and coiling second siding ring thereon, and second siding ring is cast with insulating protective layer 5 outward, and annular current transformer body endoporus sidewall is provided with cover 7 in the plastics, to guarantee the cast location of second siding ring; Current transformer body 8 is fixed on the base 9; secondary side wiring group 4 is fixed on the insulating protective layer of instrument transformer upper top; this routine current transformer body center is a primary side through wires hole 6; fixedly the insulating protective layer pour mass position of secondary side wiring group also is provided with secondary side through wires hole 3, nameplate 1, lead sealing nut 2.
This example is the embodiment that is provided with primary side wiring group 10 in current transformer body 8 centres, and this routine secondary side wiring group 4 also is fixed on the insulating protective layer of current transformer body upper top.
