Product Description
The motor soft starter is a new type of starting equipment which is designed and produced by using power electronics technology, microprocessing technology and modern control theory. The product can effectively limit the starting current of AC asynchronous motor when starting, can be widely used in fan, pump, conveying class and compressor and other loads, is the traditional star/triangle conversion, autobuck, magnetic control buck and other buck equipment ideal replacement products.
Main role
First: effectively reduce the starting current of the motor; It can reduce the distribution capacity and avoid the investment in power grid capacity.
Second: reduce the starting stress of the motor and load equipment; Prolong the service life of the motor and related equipment.
Third: the soft stop function effectively solves the problem of stopping surge of inertia system; Is the traditional starting equipment can not achieve.
Fourth: it has six unique starting modes; To adapt to the complex motor and load situation, to achieve a perfect starting effect.
Fifth: with perfect and reliable protection function; Effectively protect the use of motor and related production equipment safety.
Sixth: The application of intelligent and networked technology of motor soft starter makes the motor control technology adapt to the higher requirements of the rapid development of power automation technology.
Product characteristics
Starting mode: Select different starting modes and parameter Settings according to the load characteristics, which can maximize the motor to achieve the best starting effect; Three starting modes: voltage ramp starting -- can get the maximum output torque; Current limiting starting - can effectively limit the starting current; Point motion -- can realize the test debugging function.
High technical performance: Due to the use of high-performance microprocessor and powerful software support functions to simplify the control circuit. No need to adjust the circuit parameters. Consistent, accurate and fast execution speed can be obtained; High strength anti-jamming function.
High reliability: All electrical components of the motor soft starter are strictly screened, and the main control board must also go through 72 hours of high temperature cycle test and vibration test, so as to ensure the high reliability of the factory products;
Optimized structure: unique and compact modular structure and the connection mode of upper and lower line outlet, which is very convenient for users to integrate and complete sets;
Multiple protection function The motor soft starter has a variety of protection functions (such as overcurrent, overload, phase loss, overheating, etc.) for the start of the motor, which can reduce the cost of integration or complete sets and simplify the circuit.
Keyboard setting function: convenient and intuitive operation display keyboard, according to different loads, the start and stop, operation, protection and other parameters to set, modify.
Working principle
The motor Soft Starter (soft starter) is a novel motor control device that integrates the motor soft start, soft stop, light load energy saving and a variety of protection functions. It is called soft starter abroad. The soft starter uses three opposite parallel thyristors as a voltage regulator to connect it between the power supply and the motor stator. This circuit such as three-phase full control bridge rectifier circuit. When the soft starter is used to start the motor, the output voltage of the thyristor gradually increases, and the motor gradually accelerates until the thyristor is fully switched on, and the motor works on the mechanical characteristics of the rated voltage to achieve smooth starting, reduce the starting current, and avoid starting overcurrent trip. When the motor reaches the rated revolution, the start process is over, and the soft starter automatically replaces the thyristor that has completed the task with a bypass contactor to provide rated voltage for the normal operation of the motor, so as to reduce the thermal loss of the thyristor, extend the service life of the soft starter, improve its work efficiency, and avoid harmonic pollution in the power grid. The soft starter also provides the soft stop function at the same time, the soft stop is the opposite of the soft start process, the voltage is gradually reduced, the revolution is gradually reduced to zero, and the torque impact caused by the free stop is avoided.
Routine maintenance
Usually pay attention to check the environmental conditions of the soft starter to prevent operation in excess of its permitted environmental conditions. Pay attention to check whether there are objects around the soft starter that hinder its ventilation and heat dissipation, and ensure that there is enough space around the soft starter (greater than 150mm).
Regularly check whether the wiring terminals are loose, and whether the components in the cabinet are overheating, discoloration, scorch odor and other abnormal phenomena.
Clean the dust regularly, so as not to affect the heat dissipation, prevent the thyristor from being damaged due to high temperature rise, and also avoid the leakage and short circuit accidents caused by dust accumulation.
Dust cleaning can be carried out with a dry brush, and can also be used for leather tiger blowing and vacuum cleaning. For large pieces of dirt, an insulating rod can be used to remove. If conditions exist, use about 0.6MPa of compressed air to blow away.
Usually pay attention to observe the operation of the fan, once it is found that the fan speed is slow or abnormal, it should be repaired in time (such as removing oil dirt, dust, adding lubricating oil, replacing damaged or deteriorated capacitors). The damaged fan should be replaced in time. If you use a soft starter without a fan, you will damage the thyristor.
If the soft starter is used in a humid environment or easy to condensation, it should be often dried with an infrared bulb or a hair dryer to drive away moisture to avoid leakage or short circuit accidents.
