Split Reactor (Deep Current Limiting Reactor)
Split reactors (Deep Current Limiting Reactors) have no significant difference in structure from ordinary reactors. Just there is a tap in the middle of the reactance coil, used to connect the power supply, so a reactor forms two branches, each of which can be connected to one (such as the factory bus), with equal rated current.
Splitting reactor is a compensation device used in power systems, whose main function is to compensate for reactive power through the series combination of inductance and capacitance, in order to improve the stability and efficiency of the power system. Split reactors are widely used in medium voltage distribution systems, substations, and other occasions, and are an important type of power equipment.
What is a split reactor:
Splitting reactor is a special power electronic device, whose basic structure consists of two inductors and one capacitor connected in series, and the conduction state of the inductors is controlled by external switches to compensate for reactive power. The working principle of a split reactor is to use a series combination of inductance and capacitance to form a resonant circuit, which can effectively eliminate harmonic interference and voltage fluctuations in the power grid during reactive power compensation, and improve the stability and reliability of the power system.
Main features:
During normal operation, due to the opposite direction of current in the two branches, the reactance of the two branches decreases, resulting in reduced voltage loss. When a short circuit occurs in one branch of the outgoing line, the short-circuit current flows through that branch, and the load current of the other branch is relatively small compared to the short-circuit current, so its effect can be ignored. As a result, the reactance of the branch that flows through the short-circuit current increases, the voltage drop increases, and the residual voltage of the busbar is higher.
Product advantages:
1.During normal operation, the reactance of each segment of the split reactor is equivalent to 1/4 of the reactance of a regular reactor, resulting in less voltage loss caused by load current compared to a regular reactor.
2.When the branch end of the split reactor is short circuited, the reactance of each section of the split reactor increases by four times compared to the normal operating value, thus limiting the effect of the short circuit.
6.In short, when performing reactive power compensation in power systems, users need to choose the appropriate type of reactor based on specific circumstances to fully utilize its function. The split reactor has the advantages of simple structure and flexible function, and is a commonly used reactive power compensation device.
There are significant differences in structure and function between split reactors and ordinary reactors:
Different structures: Ordinary reactors consist of one inductor and one capacitor connected in series, while split reactors consist of two inductors and one capacitor connected in series and controlled by external switches;
Different functions: Ordinary reactors can only provide fixed compensation for reactive power, while split reactors can dynamically adjust the compensation amount, which has higher practicality and flexibility.
