1. Safety precautions 1. The primary requirement is to have certain electrical professional knowledge, and understand the job site, understand the equipment status, and have certain electrical operation technology. 2. Determine the electrical ...

1. Maintenance objectives of overcurrent In the frequency conversion speed regulation system, there are two devices: the frequency converter and the motor. The degree of tolerance to overcurrent is not the same. The planners of the production machinery decide on the capacity of the motor based on the principle of heat. That is, as long as the electricity ...

In power distribution equipment such as voltage distribution cabinets and switchgear at all levels of power plants and substations, the conductors connected between large electrical equipment such as generators and transformers and various electrical equipment are called busbars. Busbars, also known as busbars, are used to collect, distribute, and transmit electrical energy. The connection methods of the bus bar are ...

What are the causes of inverter damage? First, the heat dissipation of the inverter is not good In fact, we all know that too high a temperature can have a damaging effect on any device, just like the human brain, too high a temperature can also burn out the brain ...

1) Query and query fault phenomena. The fault phenomenon of the inverter is varied, for example, the same type of problem may have different problem phenomena, and different types of problems may have the same kind of problem, which brings difficulties to find the problem. However, the problem phenomenon is the fundamental basis for repairing the inverter ...

Soft starters and frequency converters are two completely different products. The inverter is used in the local area where speed regulation is required, and its output not only changes the voltage but also changes the frequency at the same time; A soft starter is actually a voltage regulator, which is used when starting a motor, and the output only changes the voltage and does not change the frequency. Change...

1) The air duct of the inverter cabinet should be planned reasonably, and the exhaust should be clear and smooth, so as to avoid the formation of vortex in the cabinet and the accumulation of dust in a fixed direction. 2) The top air outlet of the inverter cabinet should be equipped with a protective top cover to avoid debris from falling directly.

(1) Frequent starting, resulting in excessive temperature, causing overheating maintenance of soft starter. (The number of starts of the soft starter should be controlled to no more than 6 times per hour, especially for heavy loads) (2) During starting, ...

Motor soft starter is the primary selection of power electronics skills and microprocessing skills and modern control theory and design and production of advanced level of new engine equipment, motor soft starter mainly has anti-interference function, high reliability, multiple protection functions and other characteristics, according to these characteristics of electric ...

Compared with the motor driven by the inverter, the power factor and efficiency of the motor will deteriorate and the temperature rise will increase because the output waveform of the inverter contains the influence of higher harmonics. On the other hand, when the frequency conversion is driven, the same torque should be obtained as when the power frequency power supply is driven, ...

1. Classified according to the input voltage level According to the input voltage level, the inverter can be divided into low-voltage inverter and high-voltage inverter, and the low-voltage inverter is common in China with single-phase 220 V inverter, three-phase 220 V inverter, and i-phase 380 V inverter. High-voltage inverters are commonly used in 6 kV, 10 kV transformers.

There are many setting parameters of the inverter, and each parameter has a certain range of choice, and the inverter can not work normally due to the improper setting of a single parameter in use, therefore, the relevant parameters must be set correctly. ...

It is precisely because of the vigorous development of the collaborative robot industry that Synapticon Gmb ...

With the improvement of the degree of automation of packaging machinery, packaging machine inverter (hereinafter referred to as VFD) plays an increasingly important role in packaging machinery. Capsule filling machine, high-speed tablet press, bottling production line, aluminum-plastic packaging machine, cartoning machine, each equipment will use VFD, mainly ...

1. What are the factory parameters of inverter rehabilitation? N600 = 100 (often press the WR button for 3-5 seconds), it is necessary to be in the shutdown state to be effective. 2. In the parameters of the N308 motor of the inverter, [motor leakage inductance reactance] is the specified sub...

In the repair of the inverter, we often hear about overpressure problems, but underpressure problems are also common problems encountered in the use of inverters. The reason is that the main circuit voltage is lower than the lower limit caused by the maintenance action or the damage of a rectifier bridge or the instantaneous power failure of the power grid, and the input is flat. Inverter after-sales ...
