Our country generates electricity by more than 60% of the total is consumed by the motor, more than half of which are used in a variety of fan and water pump. Variable frequency speed regulation is the typical application of energy-saving for the purpose of regulating fan speed, pump. AC motor speed drive in China in recent years rapid development of new technology, variable frequency speed regulation has also been included in the national focus on organizing the implementation of energy-saving 10 resources comprehensive utilization demonstration projects of technological transformation of. Large power and large power high voltage inverter market prospect is valued by the industry. The high voltage variable frequency domain, using isolation transformer can effectively eliminate the harmonic pollution to power grid frequency, can make the design of high voltage inverter become more flexible. Multiple winding phase shifting rectifier transformer as a variable frequency device in the isolated power supply, is the core of the important element. Frequency conversion and speed regulation technology and the development of mature, be badly in need of phase shifting rectifier transformer is homebred change. I follow the market demand for the company, leading products in non-encapsulated dry-type transformer technology successfully developed based on a multiple winding phase shifting rectifier transformer. According to the transformer capacity size, with 9 side, 12 side, 15 side, 18 side and the 24 side edge unequal phase winding.
Multiple winding phase shifting rectifier transformer is designed according to the user, capacity of 250～ 6300kVA, 8%～ 14% in total impedance, efficiency of transformer in > 98.5%, with class H insulation system, diverse, beautiful and simple appearance structure, shape and size according to the user 's request, to meet user requirements for the installation of as much as possible do the small volume of the transformer, the compact structure.
1, " high " of direct power supply, output compare perfect without harmonic sinusoidal voltage, current.
In 2, H class insulation dry-type transformer, has good heat resistance and H dry-type transformer etc..
3, ultra small volume design, realizes the volume minimization.
In 4, the high efficiency of transformer, achieve more energy-saving effect.
In 5, high precision design, valve voltage precision is in 0.5% the following, transposed angular deviation in±0.50, improve the smooth operation of the degree of frequency conversion device.
6, simple unique lead connection, beautify the appearance of the transformer.
7, outstanding resistance to environmental performance, make operation and maintenance more convenient.
In 8, the maximum safety design, improves the security of the whole system.
9, targeted design, which belongs to the high voltage frequency transformer.
10, quick response, short production cycle, to meet the needs of the market.
