Renault is available in a variety of product ranges

There are many kinds of components of the inverter, different components have different functions, and different components have different specializations! In addition to the composition and application of Aideley inverter, there are also key components of inverter to provide for the operation of inverter.

According to the different degrees of short circuit, the inverter can display the short circuit of the SCF1 motor; SCF2 has an impedance short circuit; SCF3 is short-circuited to ground. Causes of the problem: insulation problems with the cable from the motor or inverter to the motor; current transformer fault; ...

More than 40 sets of RNSVG series low-voltage power generator sets and RNZB series high-voltage reactive power automatic compensation devices designed and produced by Reynolds have been successfully completed and will be delivered in the near future. This product is owned by Shanghai Reynolds ...

We need to ensure that the capacity of the inverter is matched. First of all, according to the nature of the load, the correct selection of the type of inverter. When selecting the inverter, the current value of the actual motor should be used as the basis for the selection of the inverter, and the rated power of the motor can only be used as a ...

1. What are the factory recovery parameters of Reynolds inverter? 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, is the [motor leakage inductance reactance] specified sub-leakage inductance or rotor leakage inductance react? Decide...

1. The cause of the leakage problem Some sites use frequency converters to control the motor, which will present the problem of leakage, and the leakage voltage ranges from tens of volts to 200 volts. In view of this problem, the reasons for this shortcoming are theoretically expounded and stated as follows. Depend on...

a。 When the third harmonic and disturbance signals are severe, a barrier transformer can be used to eliminate the third harmonic and disturbance signals. b。 The use of barrier transformers can generate new neutrals and avoid the abnormal operation of equipment due to defective neutrals in the grid. ...

1. The soft starter does not start and the fault-free code appears, perhaps because the control power supply is not connected, the solution is to check the power supply of the control power supply to see if the circuit connection is correct. 2. The motor starts when the motor announces a hum/no start signal, perhaps because of the thyristor/module ...

1. Clarification of the function of the control panel 1. FUN button; Press the FUN button to enter the settings menu F00; 2. Press and hold the up or down button to scroll to the code you need to set; 3. At this moment, press the FUN button to confirm, and adjust the entry parameters to the required value; 4. After the adjustment is completed, ...

The voltage waveform output by the inverter is only similar to a sine wave, but not a real sine wave, and its waveform contains a large number of harmonic components. As we all know, the higher harmonics will increase the output current of the inverter, causing the motor winding to heat up.

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 ...

Equipment selection 1. Inverter selection. When it comes to sizing, the first thing to consider is the operating conditions – whether one or more motors should be started or stopped at any time during the operation of the inverter. If the motor does not need to be started at any time during the operation of the inverter, it may only be stopped or ...

Capacitor series reactors generally adopt epoxy glass fiber multi-encapsulated parallel structure, according to the characteristics of the device site, three-phase vertical stacking, three-phase horizontal "△" and three-phase horizontal "-" type distribution. The substation in the southern area ...

The output of the inverter is controlled by PWM (pulse width modulation, similar to high-speed switching), so a high frequency leakage current will occur, if you want to install a general leakage disconnect switch on the primary side of the inverter, it is recommended to select a sensitivity current of more than 200mA for each inverter and the action time is 0.1 seconds ...

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.

First, select from the inverter "software". The reason why the factory chooses the inverter to work together with the fan is that it is hoped that the automation and intelligent design of the inverter technology can improve the speed regulation mode of the fan, and reduce the wasted energy consumption, which not only improves the wind efficiency.

The preparation of the braking resistor of the inverter is mainly to consume part of the energy on the DC bus capacitor through the braking resistor to avoid the capacitor voltage being too high. Theoretically, if the capacitor stores a large amount of energy, it can be used to release it to drive the motor and avoid energy waste. However, the capacitance of the capacitor is ...

Assuming Icu=60KA, then when a faulty current of 60KA is generated in the line, the circuit breaker can safely cut off the circuit without abnormal conditions such as contact welding and blasting. Pay attention to the extreme breaking ...

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 ...

1. EPS the first use of the emergency power supply, the battery pack should be charged continuously for 48 hours after discharging protection; 2. EPS emergency power supply to keep the whole machine dry, clean, free of dust and foreign objects, wipe with a soft cloth after shutting down, and strictly ...
