Big Rated Current

Shinenergy’s big current AC reactor with a rated current of 1400A. The current represents the size of the load. if the current is higher than the rated current, it is often because the load is too large. Of course, the machine will be damaged after a long time. If the rated current is large, it can load more powerful electrical appliances.

Big Common Inductance

Shinenergy’s big current AC reactor has a common inductance of 20uH, The value of the common inductance will directly affect the EMC performance. Its main function is to isolate the common-mode signal and attenuate external common-mode interference, thereby reducing the impact on the power supply. It can also attenuate the internal common mode signal and reduce the impact on the power grid. Large common inductance has a good suppression effect on low-frequency disturbance.

Q1: Why need to use the AC reactor?

A1: When a short circuit occurs in the power system, a large short-circuit current will be generated. It is very difficult to maintain the dynamic stability and thermal stability of electrical equipment if it is not restricted. Therefore, in order to meet the requirements of the breaking capacity of some circuit breakers, a reactor is often connected in series with the outgoing circuit breaker to increase the short-circuit impedance and limit the short-circuit current.

Q2: What’s the big current AC reactor?

A2: Shinenergy’s AC reactor, also called the AC reactor for power coordination. Its main function is to prevent harmonic interference in the power grid. It is required that its own distributed capacitance should be small, and its own resonance point should avoid the suppression frequency range, so as to reduce the interference voltage, but also ensure that the power frequency voltage drops below 2%, and the power consumption should be small.
