Liquid Resistor Soft Starting & Speed Regulation Control Device

Liquid Resistor Soft Starting & Speed Regulation Control Device


Worldwide Associates is an agent for Shanghai Surpass Sun Electric Co, for electrical equipment, soft starters, harmonic filters, PF compensators, etc. The company offers ZYQT Series of automatic liquid resistor soft starting and speed regulation control device. It has applications as soft start, speed regulation and energy-saving operation of such loads as pumps and air blower fans driven by large and medium wound-rotor asynchronous motors with rated voltage of 380 V~12 kV. It is also used for protection of motors against the impulse or the surge current, which usually occurs in the variable and impulse-ridden load as found in rolling machines in metallurgy industry. Since the voltage of the device has no direct relevance to the stator voltage of the wound-rotor motor, the device is applicable to motors with various voltage and capacity. Main technical parameters: initial start current ? Iq?1.3Ie (A); speed regulation rates ? 2:1 for air blower fan and pump; recommendable range ? 60%~90% ne; characteristics of impulse suppressing ? S?0.12 for rolling machine, based on its working conditions; energy saving rates ? ? 30% (average value) for air blower fan and pump; normal working temperature of variable liquid resistor ? 0~70?C; and protection level ? IP20, IP30. Standards adopted: low voltage switch set and control device GB/T14048.1-1993 IEC947-1: 1988GB7251.1-1997 IEC439-1: 1992; and automatic liquid resistor starting device, speed regulation and compensation control device Q/FZR1-2003.
