Abstract
The invention discloses a convertor transformer for a polycrystalline silicon reduction furnace. The convertor transformer comprises a high-voltage side winding and a low-voltage side winding. The high-voltage side winding is axially divided into two windings with same phase structures. The divided high-voltage windings which are parallelly connected share an excitation-free voltage regulation switch, thereby being simultaneously subjected to voltage regulation. Phases of the high-voltage windings are parallelly connected in triangular manner in the transformer. The low-voltage side winding corresponds to the divided high-voltage side winding. Heads and tails of two low-voltage windings which are insulated with each other are led out, with phases being independent and no electric connection. The low-voltage windings are equal in structure. Each low-voltage winding comprises 5 tapping windings in series connection. The tapping windings are independent in single-phase running and output different single-phase voltage, current and impedance. According to the arrangement, two loads are supported by one transformer other than two transformers of the prior art, reliability and stability of running is improved, fewer transformers are used, space is saved, and cost is saved.
