Explosion-proof generator VSG-315S-4U3

Explosion-proof synchronous generators type VSG with a brushless excitation system designed for use as an independent source of three phase alternating current with frequency 50 Hz voltage 400 V. The level of protection of generators – explosion with type of protection "flameproof enclosure" and "intrinsic safety" and marking 1ExdibIIBT4. Type of climatic performance – U3. The nominal mode of operation – S1. The design of the generators – ІМ1001. Cooling method of generators – ІСА01А51, TSS – natural air. The degree of protection of generators – IP54, TSS – IP21. Initial excitation of the generators is provided by short-term supply of a DC voltage of 110 V. Power external power supply at least 150 watts. Generators have bearings with grease lubrication. Connection of generators with a drive mechanism by means of flexible or gear coupling. On the movement side of the shaft of the generator should not be submitted radial and axial loads. Insulation of the stator winding of thermosetting type "Monolit–2" of insulation class "F". Winding insulation rotor insulation class "H". The stator windings connected in a star with a conclusion the four corners in the terminal box. The generators have right direction of rotation. Explosion-proof generators VSG replace generators manufactured by leading Western companies. The generators can be equipped with bearings of SKF or FAG.
