They are used to control the phase shift between current andvoltage in three-phase or single-phase networks.
When a three-phase motor is connected to a single-phase network, the efficiency will decrease by 30-50%.
For example, for single-phase networks, only those devices that can work with networks from 220 V with a load up to 16 A are suitable.
Most three-phase electric motors are connected to a single-phase network of"triangle" circuits(rice 1).
The main winding is connected to a single-phase network, the starting one- through the provided working capacitor.
In order to make a DC welding machine yourself, a high-power power source is needed,which is capable of converting the nominal voltage of a conventional single-phase network and providing a constant value of the corresponding current.
If the device is powered from a single-phase network of 220 V, it differs in the characteristics of the additional winding.
If the three-phase motor has been connected according to the scheme"triangle",then to single-phase network connected on the same circuit with addition of capacitor.
Of course, it can be connected to a single-phase network, the acceptance and sealing of such a device will depend on the inspector.
If the welding machine is powered from a single-phase network of 220 V, the connection of the primary winding of the transformer should be made differently.
As for the devices that are designed to operate from a single-phase network, they, as a rule, calmly withstand voltage fluctuations in the range of 220 V± 15%.
For example, if the unit will be used to work with a single-phase network, it is unlikely that it will be possible to exceed the current value of 200 A, we must not forget about it.
On this basis, for a single-phase 220V network, we must use a three-core wire.
