WKGY2 High-Voltage Liquid Resistance Soft Starting Cabinet |
 |
|
General of WKGY2 |
|
WKGY2 series liquid resistor soft starting cabinet is connected to the rotor
circuit of three-phase 380V - 10KV winding type motor and to be used to start
the motor.This starter changes the starting resistor according to the
characteristics of mechanical load, and adjusts the starting torque, so that the
motor is in the best starting state.The starter adopts non-step regulating, and
starts the motor by connecting the motor rotor circuit to the additional
resistors in series, which has many advantages such as small starting current
(usually no large than 1.3 times of the rated current), large starting torque
(close to the biggest torque of motor),high power factor, long operation
life,easy maintenance and so on.In addition, when the motor is started,
procedures such as preparation, acceleration and operation should be completed
which totally eliminates the mechanical impact and realize smooth starting.This
soft starter is applied to many industries such as mine, metallurgy,
construction material and chemistry.lt is to be used in motor transmission
devices such as ball mills, rolling mills, crushers, fans and belt conveyers to
start the slip ring motors which is the idealist new generation of frequency
sensitive rheostat cabinets and reastor starting cabinets. |

Operation:
First, connect the connecting wires between the starting cabinet and the motor stator
cabinet in accordance with the connection diagram, then, connect the power
supply switch QF and the pilot lamp of the power supply switch cabinet to supply
electricity to the motor. Controlled by liquid starting cabinet, the motor will
then complete the starting process automatically according to the preset
starting current and rach the rated rotary speed.
Maintenance:
In order to ensure the long term reliability of the product, the following items
should be amintained regularly:
● Whether the liquid level of the resistor liquid reaches the label height, if
not, then water should be added to dilute it, while it should not exceed the
highest liquuid level Iduring dilution.
● Whether the temperature of the resistor liquid exceeds the allowed maximum
value.
● Whether the electric instruments and pilot lamp indicate the right value, and
whether the displayer works normally.
● Whether the electric instruments and pilot lamp indicate the right value,and
whether the displayer works normally.
● Whether there is any unusual condition in mechanical parts, drive motor and
movable electrode board.
Items for regular test:
An annual voltage reistance test should be carried out to the liquid resistor,
and test to see whether the movable board and static board is rusty. |
