Leling BP4-05003/05613 ball mill supporting frequency sensitive rheostat
(1) the installation should be firmly fixed on the base, when the base for ferromagnetic material should be placed above 10mm nonmagnetic spacers in the middle pad, to prevent the effects of the characteristics of frequency sensitive rheostat;
(2) the cable connecting line should choose the appropriate section according to the rated current of the motor rotor;
(3) test before, should first measure the insulation resistance to earth, its value is less than 1M, it must first be used for drying.
(two) use and adjustment
(1) just said motor starting current closing fail; too big, start too fast, too large to mechanical impact, can use more turns of the tap. Such as the winding has several groups (several units) in parallel, can tear down a group, or even to series.
(2) motor does not start after closing the starting current is too small, or even starting, but stable high speed, adjustable coil tap, a smaller number of turns of the tap; there are several groups such as winding in series, can be removed in a group, and even change for the series, or the connection to Y by winding Delta connection.
(3) Chengdu BP4-08005/10020 frequency sensitive rheostat taps for: zero, 20%, 90%, 100%, 90% connection factory
Chengdu BP4-08005/10020 frequency sensitive rheostat product type many users need to provide product order number is not required to indicate the type of equipment name of motor power and motor rotor current our company technical personnel according to the user to provide parameters for you to design the most perfect products supporting the use of
Heavy load starting type for ball mill, crusher, brick, brick, stone machine, belt machine etc.. The frequency sensitive rheostat is a great loss of the iron core reactor, using thick steel, iron knot with thick steel plate to form a skeleton as magnetic induction and eddy current mechanism, steel tube with a coil, i.e. light load starting frequency sensitive rheostat. Frequency sensitive rheostat (hereinafter referred to as the rheostat) applicable to capacity from 22Kw, 50Hz, three-phase AC winding asynchronous motor as the light load and heavy load starting occasionally (e.g., water pump, air compressor, rolling machine, air compressor, etc.) or repeated short-term work system use (such as: capacity from 2.2Kw to 125Kw the bridge crane, lifting platform, mine transfer zone etc.). Second numbers: 0: no protection, no special protection 1: drip, drip should not directly into the vertical motor 2:15o drip, drip into the 15O and the plumb line angle range, should not directly into the interior of the motor 3: anti water, and pouring water into the plumb line angle range 60O that should not be directly into the inside of the motor 4: splash, splash in any direction of the motor should be no harmful effects: 5 anti water spray in any direction of the motor should be no harmful effects of 6 anti waves or impose water spray, violent waves or the strength of the motor should be no harmful effect 7: water immersion under pressure and motor, time immersed in water, the water should be no harmful effects of 8: diving, motor at the prescribed pressure dipped in water for a long time, the water should be no harmful effect The most commonly used protection level

Working conditions: 1 altitude of not more than 1000 meters. 2 ambient temperature is not higher than +40 and not less than -30. 3 air relative temperature is not greater than 80% (20 DEG C + + C). 4 medium without explosion risk, and no enough to corrode and destroy the insulation of the gas and conductive dust. 5 rain and snow prevention equipment and is not a place full of steam. 6 no violent vibration and shock.
BP4 series of frequency sensitive rheostat for three-phase AC 50HZ, winding motor capacity of 14 to 1000kW, connected to the motor rotor circuit, as starting occasionally. This series of frequency sensitive rheostat light and heavy load starting starting two, light load start type for air compressor, chiller, machine, fan, heavy load starting type for ball mill, crusher, belt machine etc.. Frequency sensitive rheostat (hereinafter referred to as the rheostat) applicable to capacity from 22Kw, 50Hz, three-phase AC winding asynchronous motor as the light load and heavy load starting occasionally (e.g., water pump, air compressor, rolling machine, air compressor, etc.) or repeated short-term work system use (such as: capacity from 2.2Kw to 125Kw the bridge crane, lifting platform, mine transfer zone etc.). A) at no more than 4000m; b) ambient temperature is not higher than +40 and not less than -30 DEG C; c) the air relative humidity of not more than 85% (20 + - 5 DEG C); d) a rain and snow is not a place full of steam; E) to allow the general vibration and impact place) in F; tilt and vertical angle into any place; g) in no danger of explosion in the medium and medium without gas sufficient corrosion and damage to the insulation and conductive dust;
