The description of 150KVA isolation transformer

150KVA isolation transformer is a safe power supply, generally used for machine repair and maintenance which plays the role of protection, lightning protection and filtering.

The principle of 150KVA isolation transformer is the same as that of ordinary transformer. Both use the principle of electromagnetic induction. 150KVA isolation transformer generally (but not all) refer to 1: 1 transformers. Since the secondary is not connected to the ground, there is no potential difference between any secondary line and the ground, but it is safe to use. Often used as a maintenance power source.

The power supply for controlling 150KVA isolation transformer and electronic tube equipment is also an isolation transformer. Power sources such as tube amplifiers, tube radios and oscilloscopes and lathe control transformers are 150KVA isolation transformer. First of all, we usually use one line of AC power supply voltage connected to the ground and the other line has a potential difference of 220V between the ground and the ground. Contact with people can cause electric shock. The secondary of the 150KVA isolation transformer is not connected to the ground, and there is no potential difference between any two wires and the ground. There is no electric shock when people touch any line, so it is safer.

Secondly, the output end of the 150KVA isolation transformer is completely "open" isolated from the input end which effectively plays a good role in filtering the input end of the transformer (the power supply voltage supplied by the power grid). Thus providing a pure power supply voltage to the electrical equipment.

Another use is to prevent interference that can be widely used in the transmission and distribution of subways, high-rise buildings, airports, stations, docks, industrial and mining enterprises and tunnels.

150KVA isolation transformer refers to a transformer where the input winding and the output winding are electrically isolated from each other, to avoid the danger of accidentally touching live objects (or metal parts that may be charged due to insulation damage) and the earth at the same time. Dry-type transformers are the same, but also use the principle of electromagnetic induction that mainly to isolate the primary power circuit and the secondary circuit floats to the ground to ensure the safety of electricity.

The function of 150KVA isolation transformer

The main function of the 150KVA isolation transformer is to isolate dangerous voltages. The electrical insulation of the primary and secondary sides is completely insulated, and the circuit is also isolated. In addition, the high-frequency loss of its iron core is used to suppress high-frequency clutter from entering the control loop. The 150KVA isolation transformer is used to suspend the secondary ground and it can only be used in the occasions with small power supply range and short circuit. At this time, the capacitance current of the system to ground is too small to cause personal injury. Another important role is to protect personal safety. With the continuous development of the power system,150KVA isolation transformer plays an increasingly important role as a key device in the power system. Its safe operation is directly related to the reliability of the operation of the entire power system. Transformer coil deformation means that the coil occurs after the force is applied. Dimensional changes in the axial and amplitude directions, body displacement, coil distortion, etc. There are two main reasons for the deformation of the 150KVA isolation transformer coil: one is the inevitable impact of external short-circuit faults during the operation of the transformer. The second is the accidental collision of the transformer during transportation and lifting.
