Application of YBBP frequency explosion - proof motor

This series of motors meet the explosion-proof performance in line with GB3836.1-2010 "Explosive environment Part 1: General requirements" and GB3836.2-2010 "Explosive environment Part 2: Flameproof enclosure" d "protected equipment" Into a flameproof motor, with an explosive gas environment for Zone 1, Zone 2 dangerous places. As a prime mover use, can be widely used in mining, machinery industry, petrochemical industry, power plants and other industrial and mining enterprises, driving a variety of general machinery: such as compressors, pumps, crushers, cutting machine tools, transport machinery and other machinery and equipment.

BS4683 and EN50018 regulations, made of flameproof. Explosion-proof mark for the ExdI, ExdIIAT4, ExdIIBT4, for explosive gas mixture exists in the place.

ExdI is suitable for the presence of methane or coal dust in an explosive mixture of coal mine underground non-mining face environment.

ExdIIAT4 is suitable for use in Class II Class A, where the temperature group is in the presence of explosive gas mixtures for T1, T2, T3 and T4 groups.

ExdIIBT4 is suitable for use in Class B Class B, where the temperature group is in the presence of explosive gas mixtures for T1, T2, T3 and T4 groups.

        ExdIICT4 is suitable for use in Class C Class C, temperature groups for T1, T2, T3 and T4 explosive atmospheres

Structural Design of YBBP Frequency Conversion Explosion Proof Motor

Structural design, mainly to consider the non-sinusoidal power supply characteristics of the inverter motor insulation structure, vibration, noise cooling and other aspects of the general attention to the following questions:

1) Insulation class, usually F-class or higher, to strengthen the insulation and line insulation strength, in particular, to consider the ability of insulation impact resistance.

2) on the motor vibration, noise problems, to take full account of the motor components and the overall rigidity, try to improve its natural frequency, in order to avoid resonance with the force wave phenomenon.

3) Cooling: the general use of forced ventilation cooling, the main motor cooling fan using a separate motor drive.

4) to prevent shaft current measures, the capacity of more than 160KW motor bearings should be used insulation measures. Mainly easy to produce magnetic circuit asymmetry, will also produce shaft current, when the other high-frequency components generated by the combination of current, the shaft current will be greatly increased, resulting in bearing damage, so generally take insulation measures.

5) For constant power inverter motors, when the speed exceeds 3000 / min, should use high temperature special grease to compensate for the bearing temperature rise
