220kV double split transformer

In order to solve the problem of large-scale super capacity centralized power generation of new energy power stations, double split structure is adopted. Each phase of a double-split transformer consists of a high-voltage winding and two low-voltage winding with the same voltage and capacity. The double split transformer normally transmits electrical energy between the high and low voltage windings. Two low-voltage windings of the same voltage and capacity can be operated separately or in parallel to bear different loads. Mainly used in wind power, photovoltaic and other new energy power generation markets and large state-owned enterprises.

35kV rectifier transformer

Rectifier transformers that provide power for electrochemical industrial rectifier devices are widely used in various fields, in order to improve the DC voltage waveform after rectification and the influence of higher harmonics of the rectifier device on the power grid and communication equipment, the number of phase on the valve side of the rectifier transformer is increased to six phases and twelve equal. Because the rectifier winding current is non-sinusoidal and contains many high order harmonics, in order to reduce the harmonic pollution to the power grid and improve the power factor, the pulse number of the rectifier equipment must be increased. The product has the characteristics of small footprint, easy maintenance and low loss. Widely used in hydrogen production, chemical industry, steel industry and so on.

10kV distribution transformer

Distribution transformer is the latest generation of energy-saving transformer, which has been widely used in distribution network.
