Basic Overvie
The inverter cabinet with reactor is mainly composed of inverter, AC input reactor, DC reactor (optional),
output reactor (optional) and peripheral control, protection, display and other electrical components and cabinets.
Among them, the inverter, as the core component, controls the power control equipment of the
AC motor by changing the frequency of the motor working power supply.
During installation, the short-circuit copper busbar between the main circuit terminals P(+) of the inverter needs to be removed,
and then the DC reactor is connected between P(+). In addition, according to the system working conditions, EMI filters,
brake units, brake resistors, contactors, intermediate relays, thermal relays, programmable controllers (PLCs), programmable
operation terminals (GOTs), electric meters, cooling fans and other components can also be installed in the frequency conversion cabinet.
Advantages And Characteristics
Under light or no-load conditions, the speed of the motor can be reduced, thereby significantly reducing energy consumption.
According to statistics, the energy-saving rate of using a variable frequency control cabinet is generally around 20% -45%.
The variable frequency control cabinet can maintain a constant speed under different load conditions,
thereby improving production efficiency.
The variable frequency control cabinet can reduce the wear and tear of motors and mechanical equipment,
lower maintenance frequency and costs by controlling the running time and current fluctuations.
The accuracy of variable frequency control motor speed is improved, so it can keep the system pressure change of
the pipeline network within the range of 3pisg, that is, within the range of 0.2bar, effectively improving the quality of the working conditions.
The addition of an incoming line reactor is used for anti-interference, to prevent the inverter inside the inverter cabinet
from interfering with other equipment, while the outgoing line reactor is used for filtering. The general frequency conversion carrier
frequency is 2~10 khz, which can make the output waveform smoother.
The incoming line reactor is used to prevent the inverter from generating harmonic interference to the power grid and surrounding equipment.
Since the inverter output is a high-frequency rectangular wave, the AC waveform output by the inverter should be optimized.
In addition, the grounding capacitance on the inverter outlet side can be prevented, and the cable length from the inverter to the motor side can be extended.
Electrical Systems And Control:
Electrical systems and control involve the design, operation and management of electrical circuits and devices.
It aims to regulate power flow, ensure stability and optimize performance. Applications span from home appliances to large - scale industrial setups.
Professionals in this area need to master electrical principles and control strategies.
