" Without going into technical details, we form the two rules. Consumption power single-phase load should not exceed 1 / 3 of the nominal three-phase output power aggregate. In other words, a 9-kilowatt three-phase generator set can be powered by no more than W-kilowatt single-phase heater! If there are multiple single-phase loads of the difference in their power consumption should not exceed 1 / 3 'phase imbalance' ('phase imbalance' – that same 1 / 3 of the rule 1). Incidentally, this is the ideal value realized for high-power stations. In simpler units, this option is less. Synchronous and asynchronous generators Speaking popularity, synchronous alternator structurally more complex: for example, it has on the rotor are inductors.
Induction generator is arranged much simpler: it resembles an ordinary flywheel rotor. As a consequence, such a generator is better protected from moisture and dirt (say he has 'closed' structure), and It's time to remember about the class of protection. Protection class It is denoted by two letters (IP) and two numerals. The first digit indicates: 0 No protection 1 Protection against objects> 50 mm 2-Protection of objects> 12 mm 3-protection against objects> 2.5 mm 4-Protection of objects> 1 mm 5-dust protection second digit indicates: 0-1-no security protection from vertically falling water drops 2-Protection against drops of water falling at an angle of 15 degrees to the vertical 3 Protection against splashing water, falling at an angle 60 degrees to the vertical 4-protection spray, spray on all sides 5-protection against water jets from all sides Synchronous generators are usually correspond to the class IP 23, whereas asynchronous – IP 54.
