Ydq Liquid Resistor Rotor Soft Starter - China

YDQ5 liquid resistor rotor starters (hereinafter

referred to as starters) are the new kind of starting devices developed

for improving the starting feature of large- and medium sized wire-wound

AC asynchronous motors.

Having solved the problems of frequency

sensitive resistor starters which are high in impact current, difficult

in starting and not easy to operate, the starters of this are suitable

for the heavy-load starting of the motors of ball grinding mills, air

compressors, crushers, large-sized blast fans and large-sized pumps

which are used in the industrial branches of building materials,

metallurgy, chemical industry, mining.

They are the ideal substitutes

for frequency sensitive starters and metal resistor starters.

Characteristics

1 Fundamental Principle

Allow the relative distance between the two parallel plates in the conductive liquid to decrease progressively up to zero through a mechanical driving device and make the resistance value run into the return circuit of motor rotor decrease continuously, so as to realize the heavy-load smooth starting of large- and medium-sized wire-wound motors.

2 Technical characteristics

2.1 The starting current is low but constant without impact on power network; the starting current is no more than 1.3 times the rated current.

Therefore the requirements of the heavy-load starting of motor for transformer capacity can be decreased, reducing lump sum investment.

2.2 It is smooth in starting, so as to lower its impact on the mechanical equipment, and the service life of the mechanical equipment and motor can be prolonged by about 30 percent.

2.3 It is high in its heat capacity, and it can start for 3~10 times continuously.

2.4 It can still start under low voltage state.

Smooth start can be ensured so long as the voltage of the power network can guarantee the motor to operate normally.

2.5 It is simple in structure, easy to maintain.

Its reliability is more superior than that of frequency sensitive, oil-soaked type resistors.
