描述:
Explosion-proof motors are manufactured with protection type "e", with explosion protection marking 1Ex e IIC T3 Gb X or 1Ex e IIB T3 Gb X according to GOST 31610.0-2014 (IEC 60079-0:2011), and are intended for operation in hazardous areas of class 1 according to GOST 31610.10-2012 (IEC 60079-10:2002) of premises and outdoor installations in which formation of explosive mixtures of groups T1-T3 and explosion category IIB or IIC is possible. There is a certificate of conformity with the Technical Regulations of the Customs Union "On the safety of equipment for work in explosive environments" (TR CU 012/2011). When operating in the intermittent-short-term mode (S5) at a rotation speed below the nominal, the engine allows for a torque overload of 1.5 Mn for 60 s with a cycle duration of 100-110 s. The electric motor is powered by a frequency converter using the PWM-AIN system. The converter supply voltage is 660 V. The frequency of the supply network voltage is 50 Hz. Supply voltage deviation (long-term) ±10%.
