Voltage regulating transformer

The invention discloses a voltage regulating transformer, and the transformer comprises a base; a compensation transformer and a contact type voltage regulator which are installed on the base, whereinthe compensation transformer and the contact type voltage regulator are jointly installed and fixed on the base through an anti-seismic frame; and a shell which is independently arranged on the foundation and is set around the base, the compensation transformer, the contact type voltage regulator and the anti-seismic frame. Compared with the prior art, the base of the voltage regulating transformer is arranged to be the integral supporting piece formed by welding the angle steel and the steel plate, the compensation transformer, the contact type voltage regulator and the base with the high anti-seismic property are connected into a whole through the anti-seismic frame, and the integral anti-seismic property of the voltage regulating transformer is improved. In the earthquake process, thevoltage regulating transfo
