1. Overload protection function: The soft starter introduces a current control loop, so that the change of motor current can be tracked and detected at any time. By increasing the setting of overload current and the anti-time control mode, the overload protection function is realized, so that when the motor is overloaded, the thyristor is turned off and an alarm signal is issued. ...

The high-voltage inverter has been designed with the safety of the user in mind. However, due to the energy storage capacitor installed inside the power unit of the inverter, it may still carry a high voltage after disconnecting the power supply, and some parts generate a lot of heat, so contact is prohibited. When working on or near the inverter, please ...

Misunderstanding: connect electromagnetic switches and electromagnetic contactors in the output circuit of the inverter In actual use, some occasions require the use of contactors for frequency converter switching: such as when the frequency conversion is faulty, switch to the power frequency operation, or when the one-to-two method is adopted, a motor is faulty, and the variable frequency is used.

The use of Reynolds inverters in industrial production is very important, in addition to speed regulation, soft start effect, the important thing is to be able to save energy. There are many functional parameters of Reynolds inverter, and there are generally dozens or even hundreds of parameters for users to choose. In practice, it is not necessary to ...

1) Ramp boost soft start. This starting method is simple, does not have current closed-loop control, and only adjusts the conduction angle of the thyristor to make it add a certain function with time. The disadvantage is that because there is no current limit, in the process of motor starting, sometimes a large impulse current is generated.

Variable frequency speed regulation can be used in most motor drag occasions, because it can provide accurate speed control, so it can easily control the rise, descent and variable speed operation of mechanical transmission. The use of frequency conversion can greatly improve the efficiency of the process (the variable speed does not depend on the mechanical part) and at the same time ...

With the rapid development of China's national economy, the supply and demand situation of oil and gas resources is becoming increasingly severe, and the import of oil and gas is increasing year by year, so it is urgent to expand the field of domestic oil and gas exploration and development. Strengthening the exploration and development of shale gas resources can make up for the lack of conventional oil and gas resources and promote the sustainability of the oil and gas industry.

The acceleration time of the Reynolds inverter is the time required for the output frequency to rise from 0 to the high frequency, and the deceleration time is the time required to drop from the high frequency to 0. Usually, the inverter uses the frequency setting signal to rise and fall to confirm the acceleration and deceleration time. When the motor accelerates, the rise of the frequency setting must be constrained ...
