Reactor Product's Name And Function
- Nov 20, 2017 -

The reactor used in the power network is essentially a hollow coil with no magnetically conductive material. It can be arranged according to the needs of vertical, horizontal and shape three kinds of assembly form. In the event of a short circuit in the power system, a large amount of short-circuit current results. Without limitation, it is very difficult to maintain the dynamic stability and thermal stability of electrical equipment. Therefore, in order to meet the capacity requirements of some circuit breakers, it is common to connect reactors at outlet circuit breakers to increase the short-circuit impedance and limit the short-circuit current.

As a result of the reactor, in the event of a short circuit, the reactor voltage drop is large, it also played a role in maintaining the bus voltage level, so that the voltage fluctuations on the bus less to ensure that non-fault line user electrical equipment Operational stability.

1, into the line reactor: also known as commutation reactor, used in the grid into the line, through the AC current, the role of line reactor is to limit the commutation converter phase voltage drop and thyristor current Rise rate di / dt and voltage rise rate du / dt, and the decoupling of the parallel converter group.

2, shunt reactor: the exchange through the inside, the role of shunt reactor is to compensate the system capacitance. It is usually connected in series with the thyristor to continuously adjust the reactance current.

3, the series reactor: which is through the exchange, the role of series reactors and compensation capacitors in series, the steady-state harmonics (5,7,11,13 times) constitute a series resonance. Usually 5 ~ 6% reactor, belonging to the high inductance reactor.

4, the tuning reactor: which is through the AC, the role of series reactor is connected in series with the capacitor, the provisions of the n-th harmonic component of the series resonance, so as to absorb the harmonic components, usually n = 5,7,11, 13,19
