690v660v480v440 to 380v to 220v200v isolated servo three-phase dry transformer

Effect

The main function of the isolation transformer is to completely insulate the electrical on the primary side and the secondary side, and also to isolate the circuit. In addition, the high-frequency loss of its iron core is used to prevent high-frequency clutter from entering the control loop. Using an isolation transformer to suspend the secondary to the ground can only be used in occasions with a small power supply range and short lines. At this time, the capacitance current of the system to ground is too small to cause personal injury. Another very important role is to protect personal safety! Isolate dangerous voltages.

With the continuous development of the power system, the transformer, as a key equipment in the power system, plays an increasingly important role. Its safe operation is directly related to the reliability of the entire power system. Transformer coil deformation refers to the occurrence of the coil after being stressed. Dimensional changes in the axial and width directions, body displacement, coil distortion, etc. There are two main reasons for the deformation of the transformer coil: one is that the transformer is unavoidably impacted by an external short-circuit fault during operation; the other is that the transformer is accidentally collided during transportation and hoisting.

The main technical parameters

Power

The magnetic flux of the transformer core is related to the applied voltage. The excitation current in the current does not increase with the increase of the load. Although the iron core will not saturate when the load is increased, the resistance loss of the coil will increase. If the rated capacity is exceeded, the heat generated by the coil cannot be dissipated in time, and the coil will be damaged. If the coil you use is made of superconducting material, the current will not increase. It causes heat, but there is impedance caused by magnetic leakage inside the transformer, but the current increases, the output voltage will drop, the greater the current, the lower the output voltage, so the output power of the transformer cannot be unlimited. If you say again that the transformer has no impedance, then when the current flows through the transformer, it will produce a particularly large electromotive force, which can easily damage the transformer coil. Although you have a transformer with unlimited power, it cannot be used. It can only be said that with the development of superconducting materials and core materials, the output power of transformers of the same volume or weight will increase, but not infinite!

Nature

Isolation transformers are safe power supplies and are generally used for machine maintenance and protection, lightning protection, and filtering. The primary and secondary voltages of the isolation transformer can be customized according to requirements. The output end of the isolation transformer is completely "open circuit" isolated from the input end. Whether it is required to have a casing, etc., it can be carefully designed and manufactured according to the requirements of users.

Note

There is no gas vapor, chemical deposits, dust, dirt and other explosive and corrosive media that seriously affect the insulation of the transformer at the installation site.
