Can't soft starter and inverter be clearly separated? Let's learn together today.

The inverter changes the output frequency and voltage at the same time, that is, it changes the n0 on the motor running curve, so that the motor running curve moves down in parallel. Therefore, the frequency converter can make the motor with a smaller starting current, and at the same time make the motor starting torque reach its maximum torque, that is, the frequency converter can start the heavy load.

Detailed explanation of frequency converter maintenance method

1. check the lubricating oil. The lubricating oil of the frequency converter generally needs to be replaced every year or 6000 hours of use. During the replacement process, the oil of the frequency converter should be heated to about 50 ℃, and then the oil pan should be unscrewed to drain the oil. After the oil drain is completed, the oil pan should be unscrewed again, the filter screen should be cleaned and installed back, and finally the oil should be added.

10 items of soft starter need regular inspection and maintenance

Soft starter is a device used to control the start of the motor. It makes the motor start smoothly by gradually increasing the voltage or current, avoiding the impact and damage caused by the traditional direct start method. In order to ensure the normal operation of the soft starter and extend its service life, the following are 10 items of the soft starter that require regular inspection and maintenance.

What is the principle of motor soft starter?

The motor soft starter is a motor control device, its main function is to smoothly start the motor and reduce the impact of the starting current on the power grid and the motor itself. The working principle of the soft starter mainly involves the control of the thyristor. A thyristor is a semiconductor device that can adjust the voltage applied to the motor by controlling its conduction angle.

Main features of active filter

Active power filter is mainly composed of load current separation, command current regulation, output current control, drive circuit and main circuit. It uses a current-type converter and connects the reactor to the system. By adjusting the instantaneous amplitude and phase of the AC-side inverter output voltage, or directly controlling the AC-side output current, the device emits or absorbs broadband reactive power.
