150 kVA Isolation Transformer, 3 phase, 240 Volt to 400 Volt

Three phase 150 kVA isolation transformers is 50/60Hz rated, dry type air self cooling of cooling method, convert 240 Volt voltage to 120 Volt voltage. The lower operating costs, lower heat emissions make this transformer ideal for a wide range of applications.

Generally, isolation transformers with power above 150KVA will be equipped with an alarm, which is used to detect the temperature of the transformer. When the temperature of the transformer rises to 150 degrees, the alarm will be triggered. At this time, the transformer needs to be manually suspended or stopped. Wait until the transformer temperature returns to normal, then continue to use.

Tips: Difference between isolation transformer and voltage regulator

As we known, electricity is capable of generating a magnetic field that is also converted into electricity. The principle of single phase or three phase isolation transformer refers that a coil charged with alternating current generates an alternating magnetic field and this alternating magnetic field passes through another coil where voltage will be induced. The transformer ratio is related to the number of these two windings. In brief, under the principle of magnetic coupling, transformer is made of original edging windings and the voltage of both coil ends is directly proportional to the number of windings. Therefore, the transformer ratio is determined by the number of original edging windings.

It is obvious that transformer is not a voltage regulator, because the auxiliary edging voltage changes with the original edging voltage.

Voltage regulator follows the principle of negative feedback. For example, turn on the tap to half and install a sensor at the exit of tap to detect the amount of water. If the amount of water is too large, the tap will be triggered to turn down automatically. On the contrary, if the amount of water is too small, the amount of water will be triggered to turn up automatically till a constant water flow. The principle of voltage regulator is as follows: There is an error amplifier inverting input divider resistance sampling circuit that can detect the changes of output voltage can be compressed into an integrated chip in the regulator. When the output voltage changes, the feedback on the circuit detected with voltage changes will be provided to the private service motor by the chip and the automatic adjustment of electric brush position will be activated by the pivoted arm triggered by a private service motor in order to stabilize the output voltage, which is the simplest voltage regulator.
