Abstract

Typically, input voltage selection on both ferroresonant transformers and straight transformers is accomplished by changing positions on a terminal block. As shown in Fig. 1, this method involves the use of considerable mechanical hardware including mounting brackets, screws, standoffs, safety shields, insulating strips, and the terminal block.

Construction for Selective Voltage Application to Power Transformer

Typically, input voltage selection on both ferroresonant transformers and straight transformers is accomplished by changing positions on a terminal block. As shown in Fig. 1, this method involves the use of considerable mechanical hardware including mounting brackets, screws, standoffs, safety shields, insulating strips, and the terminal block.

This mechanical hardware is eliminated by the use of a molded bobbin. As shown in Fig. 2, the primary leads of the transformer terminate on a bobbin lug located in a recessed area of the molded bobbin. Input voltage selection takes place by connecting the input primary leads to the bobbin lugs through the use of slip-on receptacles.
