READ MOREAir-core reactors have been widely used in many industries, and their application range is wide and important. The following are several industry fields where air-core reactors are mainly used:
Power industry:
In power systems, air-core reactors play a key role, mainly used to ensure the stability of current, reduce fluctuations, and thus optimize power transmission.
It can reduce the loss of power during transmission and improve energy efficiency.
In the reactive power compensation device of high-voltage transmission systems, air-core reactors are often used in parallel with reactors to jointly adjust voltage and current to ensure the stability and safety of power systems.
Air-core reactors are also used to prevent voltage surges and harmonic distortions and protect the normal operation of power systems.
In mines and factories, air-core reactors can also be used in safe power supply systems with live tracking to prevent operators from being electrocuted and improve work safety.
Industrial manufacturing:
In the power supply and distribution systems of large industrial and mining enterprises, air-core reactors are often used to limit the short-circuit current of power lines and ensure the safe operation of power equipment.
In motor starting control, especially in the starting process of squirrel cage AC three-phase asynchronous motors, air-core reactors can be used to control the starting current to prevent excessive current from damaging the equipment.
Communication and electronic equipment:
Due to its high linearity, low hysteresis and low magnetostriction, air-core reactors are widely used in electronic circuits, communication equipment, RF power amplifiers, energy sensors and other fields.
In high-frequency circuits and precision circuits, air-core reactors are an indispensable device that can meet the requirements of high-precision and high-frequency circuits.
Other industries:
Air-core reactors are also widely used in metallurgy, chemical industry, machinery manufacturing, papermaking, coal, electroplating and other industries. The power systems and power equipment in these industries also need air-core reactors to ensure their stable and efficient operation.
The main parameters of air-core reactor performance include the following aspects:
1. Basic electrical parameters
Inductance value:
Inductance value is one of the most basic parameters of air-core reactor, which indicates the ability of reactor to block AC. The size of inductance value directly affects the effect of reactor in circuit.
Rated current:
Rated current refers to the maximum current value that reactor can withstand under normal working conditions. This parameter is crucial to ensure the safe operation of reactor.
System rated voltage:
The system rated voltage refers to the voltage level based on which reactor is designed. Reactor must be able to work stably at this voltage level without damage or performance degradation.
2. Thermal parameters
Temperature rise:
Temperature rise refers to the temperature rise caused by the heat generated by reactor during operation. Excessive temperature rise will affect the insulation performance and service life of reactor, so it is one of the important indicators for evaluating reactor performance.
Heat resistance grade:
The heat resistance grade indicates the highest temperature that the insulation material of reactor can withstand. Different heat resistance levels correspond to different insulation materials and structural designs to meet different use environments and requirements.
3. Structural parameters
Dimensions:
Dimensions include the length, width, height and other dimensions of the reactor. These dimensions are crucial for the installation and layout of the reactor and need to be selected according to the actual use scenario.
Weight:
The weight of the reactor is also one of the factors to be considered. Excessive weight will increase the difficulty and cost of installation and transportation, so it is necessary to select according to actual needs.
4. Other performance parameters
Noise:
Noise level is one of the important indicators to measure the operating quality of the reactor. Low-noise reactors can reduce the impact on the environment and improve the comfort of use.
Linearity:
Inductance linearity refers to the stability of the inductance value of the reactor as the current changes. A reactor with good linearity can maintain a stable inductance value in a wider current range, thereby improving the stability and performance of the circuit.
Mechanical strength:
Mechanical strength refers to the resistance of the reactor when it is subjected to external forces. Reactors with high mechanical strength can better resist the influence of adverse factors such as vibration and impact, and ensure the stable operation of the equipment.
Weather resistance:
For air-core reactors used outdoors, weather resistance is also an important evaluation indicator. Reactors with good weather resistance can maintain stable performance and service life under harsh climatic conditions.
