Control transformers work with electromagnetic induction principles.There are two sets of coils in the transformer.Primary coils and secondary coils.The secondary coil is outside the primary coil.When the primary coil is connected, the transformer core generates an interchange magnetic field, and the secondary coil will produce inductive electrical momentum.The turn ratio of the coil of the Satons transformer is equal to the voltage ratio.Control transformers are mainly suitable for AC 50Hz (or 60Hz), and in circuits of 1000V and below, can work continuously for a long time under the rated load.It is usually used in the control lighting and indicator lights as an electrical appliance in machine tools and machinery.
Control transformer brand
JBK-Machine Tool control transformers This series of transformers is made of silicon steel sheets and coil combinations.Type, the way the method is exposed to some parts.The dry transformer temperature controller. This series of transformers use three PT100 platinum heat resistors that are embedded in the three -phase wiring package of the dry power transformer to detect the temperature rise of the dry power transformer line package and automatically control the cooling fan according to the temperature riseThe start -stop and ultra -temperature alarm until the ultra -high temperature stick to the ultra -high temperature to ensure the safe operation of the dry power transformer.Because the current advanced RISC single -chip computer is used and combined with advanced I2C storage and adjustment technology, it is designed according to the JB/T7631 standard, which makes the temperature controller has the characteristics of simple structure, reliable operation, and strong anti -interference ability.At the same time, the temperature controller also has a black box function, which can record the temperature of the first three winding packs and the working status of the machine.
Control transformer selection
The BK series machine tool control transformers are suitable for the use of 50-60Hz and voltage to 500V.

After years of further absorbing the advantages of similar products at home and abroad, it is made of advanced craftsmanship and rigorous design.It has the characteristics of excellent performance, reliable work, low energy consumption, small volume, safe wiring, wide practicality and other characteristics. It is an ideal transformer power.Three -related isolation transformers. The products refer to the latest foreign products to develop and develop and develop imported equipment. The products are in line with VDE0550, IEC439, JB5555, GB5226 International, and national standards.The SG series triple -proof transformers are widely used in various power supply occasions with 50/60Hz, and input and output voltage do not exceed 500V.Various inputs, outputs, voltage levels of the product, connecting groups, regulating the position of the tap, allocation of winding capacity, secondary winding equipment, whether to bring shells, etc., are carefully designed and manufactured according to the users requirements.
The role of control transformer
The control transformer is a settings used to change the AC voltage, which is formed by the iron core and the coil.It can not only change the voltage of AC power, but also change impedance. When designing power, it can also change the current. In different environments, the use of the transformer is also different.For example: 1. In order to reduce the line loss from a long distance. In order to reduce the line loss, the electricity from the power plant should be increased to tens of thousands of volts (such as 11kV), and when the destination is reached, the voltage is lowered (such as 220V).2. In the electronic amplifier line, in order to achieve the least energy consumption of transition between the two line amplification, the impedance matching should be performed, and the transformer is connected to change the impedance.3. During the welding, the current required between the beakers and the welding parts is very large (tens to hundreds of people), and the voltage is small (a few volts).The welding machine is a transformer that turns high voltage (such as 220V) into a low voltage.Under the condition of not changing power, a large current generates a large current at the output end.4. Sometimes, different voltages are needed in an environment, and the transformer can be made into multiple winding or middle taps.Instead, multiple voltages are generated.5. In AC regulator, the number of circles of output coils in real time is used to achieve the purpose of the speed regulating output voltage.
