If the high-power soft starter is used to debug the cabinet, it is best to have a light bulb. . For example, 200KW with a small motor can be started very quickly, because the rated current of the small motor is small, and the high-power soft starter cannot detect the running current, it will report a phase loss fault. . If debugging, bring a light bulb and look at the three-phase trigger to measure the quality of the soft start or control loop. . . When the high-power soft starter runs with a small motor on site, pay attention to the setting of the protection parameters of the soft starter, otherwise various protection functions may fail. For example, if it is a water pump with low power, a 90KW soft start with a 90KW motor can be used. . For heavy loads, such as fans, belt conveyors, etc., it is recommended that you choose a soft start of 115KW. The 90KW soft starter is equipped with a 75KW motor. After all, the big horse-drawn trolley is relatively stable and reliable. However, high-...

The working principle of the AC contactor is to use the electromagnetic force to cooperate with the spring force to realize the connection and disconnection of the contacts. The AC contactor has two working states: de-energized state (release state) and electrified state (action state). When the attraction coil is energized, the static iron core generates electromagnetic attraction, the armature is pulled in, and the connecting rod connected to the armature drives the contact to move, so that the normally closed contact breaker is in an electrified state; when the attraction coil is de-energized, the The electromagnetic attraction disappears, the armature is re-opened, the normally open contacts are closed and released under the action of the position spring, all the contacts are reset accordingly, and the contactor is in a power-off state. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #VFD #contactor #ACcont...

If the soft start of the motor cannot protect, it means that your parameter setting is unreasonable, or even the function setting is wrong. 1. Soft start is used to start the motor to prevent too much starting current from impacting the power grid when starting. The soft-start device is only active during the start-up process. 2. Motor burning prevention is the responsibility of the motor's overload protection device. The simplest fuse is generally a thermal resistance. But the general soft starter can be achieved. 3. The motor still burns, indicating that your circuit design is unreasonable. The configuration of the device is not reasonable. Or not consider overload protection at all. I thought that as long as it was installed, it would provide overload protection. In fact, it needs to be debugged first. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #softstartechnology #softstartermarket #softstarterprice #...

Soft starter is actually a motor control device with motor #softstart , soft stop, light load energy saving and various protection functions. It is mainly a three-phase parallel thyristor and its electronic control circuit connected in series between the power supply and the controlled motor. By controlling the conduction angle of the three-phase parallel thyristor, the input voltage of the controlled motor can be changed according to different requirements, and various functions can be realized. The #inverter is mainly used where speed regulation is required. Its output not only changes the voltage but also changes the frequency at the same time; the soft starter is actually a voltage regulator. When the motor is started, the output only changes the voltage and does not change the frequency. The frequency converter manufacturer emphasizes that the frequency converter has all the functions of the soft starter, but its price is more expensive than that of the soft starter, and the stru...

Whether the intermediate relay is DC or AC, the working principle is the same, the only difference is the voltage level. The working principle of the intermediate relay is the same as that of the relay and the AC contactor. When the contactor coil is energized, the coil current will generate a magnetic field, and the generated magnetic field will cause the static iron core to generate electromagnetic attraction to attract the moving iron core and drive the AC contactor point action, normally closed contact is disconnected, normally open contact is closed, the two are linked. When the coil is powered off, the electromagnetic attraction disappears, and the armature is released under the action of the release spring, so that the contacts are restored, the normally open contacts are disconnected, and the normally closed contacts are closed.

Soft starter is a novel motor control device that integrates motor soft start, soft stop, light load energy saving and various protection functions. The main composition is a three-phase parallel thyristor and its electronic control circuit connected in series between the power supply and the controlled motor. Different methods can be used to control the conduction angle of the three-phase parallel thyristor, so that the input voltage of the controlled motor changes according to different requirements, and different functions can be realized. The soft starter changes the starting characteristics of the motor by changing the output voltage and boost time. The soft starter uses a three-phase parallel thyristor as a voltage regulator, which is connected between the power supply and the motor stator. Such a circuit is like a three-phase fully-controlled bridge rectifier circuit. When the soft starter is used to start the motor, the output voltage of the thyristor gradually increases, and...

The contactor connected in parallel with the soft starter is called a bypass contactor, because the long-term use of the soft starter to start will cause a lot of pressure on the thyristor. Excessive current of the thyristor for a long time is not good for it. At the same time, it is also easy to cause problems by relying on the circuit board to trigger the thyristor. It is better to use a traditional contactor to maintain it, because the soft start is only useful during the motor starting process and runs at the power frequency. It is the same as the usage of ordinary motors, so it is still reliable to use traditional contactors. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #softstartechnology #softstartermarket #softstarterprice #BypassContactor #BypassContactorSoftStart #ZJSHUYI #chinashuyi #shuyitop

There are two types of soft starters, one does not need an external contactor and runs directly after starting, and the other is a built-in bypass contactor. The contactor connected in parallel on the soft starter is called a bypass contactor, because the long-term use of the soft starter to start will cause a lot of pressure on the thyristor. If the thyristor is in an excessive current for a long time, and the thyristor is triggered by the circuit board at the same time, it will be prone to failure problems. It can be maintained with a traditional contactor, because the soft start is only useful in the process of starting the motor, and it is the same as that of a common motor during power frequency operation, so it is more reliable to use a traditional contactor. The soft starter is a device that can reduce the starting current of the AC motor when starting. When the motor completes the starting process, the device can start the bypass contactor according to the set time, thereby ...

First of all, when selecting an inverter, the power of the motor should be the basic principle. The rated capacity of the inverter is generally marked with KW and current. Under normal circumstances, when selecting an inverter, the corresponding three-phase general-purpose inverter is selected based on the rated KW of the motor. For example: fans, pumps and other equipment. Generally, when selecting a motor of grade 6 or above, it needs to be properly enlarged. The load needs to be controlled by a motor with a reducer, and the power of the inverter needs to be appropriately amplified. For example: cranes, coal mine winches and other equipment. The selection of the inverter should also be based on the load characteristics. If it is applied to frequent startup, the instantaneous current fluctuates greatly, or the load is heavy, the inverter with one or two gears larger can be selected. For example: sand making machine, ball mill and other equipment. When the occasion used for control is ...
