Product details
Three phase to single-phase transformer

I. Overview
This product, also known as a Scott transformer, is a transformer that converts a three-phase input into two single-phase outputs. Require two single negative teaching positions to be the same. Otherwise, the three-phase current will be unbalanced. It is widely used in specific load scenarios of industrial and mining enterprises to solve the problem of three-phase current imbalance Suitable for communication at a working frequency of 50/60Hz. The insulation and heat resistance level of this series of transformers is F. The iron core of a three-phase to single-phase transformer is made by stacking high-quality cold-rolled oriented silicon steel sheets, and the coil structure adopts circular, elliptical, and rectangular forms. Small size, excellent performance, safe and reliable.
A three-phase to single-phase transformer is a special type of transformer, also known as a T-junction transformer. It can be used to convert three-phase AC power into single-phase AC power, serving as a power source for large capacity single-phase loads to improve the imbalance of the three-phase power grid. Especially as an ideal power source for power frequency melting, it can eliminate the need for balancing capacitors and reactors.
A three-phase to single-phase transformer is a transformer that converts three-phase inputs into a single-phase output. The input phase current of the transformer is close to equilibrium in all three phases. The frequency remains undistorted. Other technical parameters and usage conditions are the same as those of ordinary dry-type transformers. It is more expensive than isolation transformers. It is widely used in specific load scenarios of industrial and mining enterprises to solve the problem of severe three-phase current imbalance. This series of products is suitable for AC 50/60HZ and working voltage below 1140V. The insulation and heat resistance levels of this series of transformers are F, B, and H. The product is produced according to the standard JB/T8750-1998 of the Ministry of Machinery.

2、 Product Features
Energy saving benefit analysis:
1. High quality cold-rolled silicon steel sheets are stacked together; Using a special dipping process and oven drying! Effectively reduced vibration and noise during operation; The introduction of new processes and technologies, such as the use of high-temperature resistant insulation materials, has made transformers more energy-efficient and quieter. Energy saving and low-energy cables are equipped with ventilation systems, ensuring smooth air flow and effectively reducing coil temperature.
2. Products with external box: all equipped with casters (below 100KVA), voltmeter, ammeter, cooling fan, temperature controller, fan for starting when the transformer temperature exceeds 80 ° C, and over temperature alarm (alarm protection for equipment safety above 100KVA when the transformer temperature exceeds 150 ° C).
