PURPOSE:To improve the workability of assembly and the operating efficiency of wiring by mounting and unifying an instrument transformer, an insulator and a conductor to a fitting, installing a relay terminal block to the fitting and facilitating connection of the transformer circuit. CONSTITUTION:An instrument transformer (CT) 4, insulators 6 and conductors 7 are integrated on the fitting 5, and a relay terminal block 5a is fitted, thus facitating connection of the CT 4. Consequently, when a cable processing chamber 9 is assembled, members in the vicinity of the CT 4 section can be constructed outside a metal enslosed switchgear 1 while wiring operation in the metal enclosed switchgear 1 can be performed before the CT 4 and the conductors 7 are incorporated, the CT fitting 5 is incorporated, and the operation of the circuit wiring of the CT 4 can be carried out to the relay terminal block 5a. Accordingly, the workability of assembly and the operating efficiency of wiring are improved. |
