<p>PROBLEM TO BE SOLVED: To obtain a transformer for gas insulation meter which can prevent concentrated connection of a plurality of lead wires to a single through terminal of a sealed terminal block. SOLUTION: A relay terminal block 16 in which a plurality of relay terminal units 18 are provided in electrical insulation state is fitted to the iron core clamping metal fittings 3 of a transformer body 2. Respective lead wires 15u1, 15vh, 15vc, 15u2a, 15u2b, and 15u2c of a low-voltage coil of the transformer body 2 are connected respectively to the corresponding ends of a relay connection conductor in the relay terminal unit 18 of the relay terminal block 16 by using driver operated screws 21a. Respective lead wires 24u1, 24u2 and 24v are connected to the other ends of the relay connection conductor of the relay terminal unit 18, where the corresponding lead wires are connected to one end, and the other ends of the relay connection conductor are connected respectively to through terminals 9u1, 9u2 and 9v corresponding to a common sealed terminal block 10 through lead wires 24u1, 24u2 and 24v.</p> |
