Shield installs loaded down with trivial details, high cost, bulky defect, thus providing a kind of current collection current transformer, earthed switch, contact box to be integrated
Contact box current transformer.
The technical solution adopted in the utility model is for achieving the above object：A kind of contact box current transformer, its bag
Include：Transformer body with inner chamber；Conductor, it is embedded in the inner chamber of described transformer body through iron core；Mutual inductor coil
It is embedded in the inner chamber of described transformer body through iron core opposite side；It is characterized in that：Also include
Contact box, described contact box is arranged on the side wall rear end of described transformer body；
Input terminal, it is arranged on described conductor and stretches out the described side wall of described transformer body and the described of rear end
Contact box connects；
And an outlet terminal, it is drawn from described conductor and locally exposes to the bottom of described transformer body, institute
State, on an outlet terminal, static contact of grounding switch is installed.
Further, a line of described conductor passes through described iron core.
Further, it is provided with the stationary contact arm being installed on described input terminal in described contact box.
Further, a described outlet terminal is the flat board with screw, a described outlet terminal adopt screw and with
The cable bond row that described static contact of grounding switch is wholely set fixes.
Further, described contact box adopts together with poured with epoxy resin with transformer body.
Technical solutions of the utility model, have the advantage that：Contact box and transformer are set to integral structure, effectively
Reduce the use space of switchgear, a leading-out terminal is directly connected with earthed switch simultaneously, decreases copper bar connection
Part and material cost, it is more convenient that integrated product setting ensures that installation is safeguarded.
