Middle frequency generator

 

Middle frequency generator is special power supply, is widely used in military and civil industry. Its main usage as following:

 

1、Using mediate frequency power supply can make rotary type electrical equipment obtain high speed. General Motors, in its input power frequency of 50Hz, its maximum speed of 3000r/min, but in some high-speed devices such as centrifugal machinery, textile machinery, high-speed grinder and radar and other equipment requires the motor speed up to more than 10 thousand even one hundred rpm, so the vast majority of intermediate frequency power supply are used.

2、Medium frequency power for electrical equipment can  reduce the size, weight, so in the aerospace, aviation and marine and other equipment are often used in medium frequency power  supply.

3、Be rectified with the intermediate frequency power supply will get better ripple factor, and therefore rectifier devices, especially for large power generation equipment commonly used intermediate frequency generator, as Vice exciter.

4、Induction heating, metal melting, intermediate frequency welding and metal heat treatment use medium frequency power supply, especially in the surface hardening of machine parts.

5、Transformer, transformer sensors are used intermediate frequency power supply voltage test.

6、As the intermediate frequency generator simple structure, reliable operation of the power supply does not produce high-frequency harmonic interference, so in the laboratory, power vehicles, radar, computers, sonar and communications and navigation equipment has also been widely applied.

 a) BP、BPZ series inverter unit

 

 

 

 

The unit is a frequency conversion device, which would be 50Hz power frequency power conversion into a single-phase or three-phase 400,500,1000 Hz intermediate frequency power supply to supply the equipment needed to use medium frequency power supply

 b) BL Series converter unit

 

The unit is a way to transform DC into AC frequency power devices, which will be 100V or 220V DC power conversion into a single-phase or three-phase AC 400 or 1000Hz frequency power supply to supply the equipment needed to use medium frequency power supply

c) BPZ、DT Series transformers with medium frequency induction generator for voltage withstand test

 

BPZ、DT series inter mediate frequency generator group is ideal power supply for this test. It can reduce exciting current and saturation level of core, shorten trial duration, and keep high reliability and safe, and low cost.

BPZ series consists of three-phase asynchronous motor, salient pole synchronous generator and the AC exciter. This unit is characterized by compact structure, small size, non-slip ring brush contact, small excitation power is, voltage regulator convenient, safe and reliable, the following capacity of 50kW.

 

DT series generator consist of pole synchronous generators  and three-phase asynchronous motor. This unit is split structure, therefore a larger capacity can be done, at present can do is to 200kW.

Capacity:15-200kW        Frequency:100Hz、150Hz, 200Hz

Output voltagae:800V,stepless adjusting 80-800V
