| According to the structure and the cooling medium, by connection, by function, According to use classification. 1, according to the structure and cooling medium: into the hollow type, core type, dry, oil-immersed, such as: dry hollow reactor Dry Core Reactor, Oil core reactors, oil hollow reactor, clamp-dry hollow reactor, wrapping dry-type hollow reactor, reactors and other cement. 2, according to the connection: two shunt reactors and series reactor. 3. Press the function: divided into current limiting and compensation. 4, according to use: Press the specific use segments, such as: limiting reactors, filter reactors, smoothing reactors, power factor compensation reactor, series reactor, balance reactor, grounding reactor, arc suppression coil, into line reactor, reactor outlet, saturation reactor, since the saturable reactor, varactor (adjustable reactor, controllable reactor), yoke flow reactor, the series resonant reactor, parallel resonant reactor and so on. Reactor as a means of reactive power compensation in the power system is indispensable. Shunt Reactors: generator full load test reactor is a prototype shunt reactors. Reactor core segments due to the presence of an alternating magnetic field attraction between the core cake, so noise is generally higher than the transformer with the capacity of about 10dB. Limiting reactor: limiting reactors are generally used for distribution lines. From the same bus feeders often leads to branch string current limiting reactors to limit the short circuit current feeder and maintain bus voltage, not because of a short circuit caused the feeder too low. Damping reactor (also commonly known as series reactor) or intensive capacitors with the capacitor bank in series to limit the inrush current of the capacitor. This role and limiting reactor is similar to filter reactor and filter reactor in series resonant filter capacitor filters, generally used for 3 times to 17 times or more times the resonant filter high-pass filtering. HVDC converter station line, phase-controlled static var compensator, medium and large fairing, electrified railways, power electronic circuits that control all power thyristor are harmonic current sources that must be filtered to prevent their entry into system. Power sector for the power system harmonics have specific provisions. Petersen Coil: arc suppression coil is widely used lOkV-6kV-level resonance grounding system. Because of the tendency of non-oil substation, so 35kV following Petersen Coil is now is a lot of dry casting. Smoothing reactor: smoothing reactors for DC after the rectifier circuit. Pulse number rectifier circuit is always limited, the output voltage in straightening always have ripple. This ripple is often harmful and needs to be suppressed by the smoothing reactors. HVDC converter stations are equipped with flat wave reactor, so close to the ideal DC output current. DC-powered electric drive thyristors, smoothing reactor is essential. DC controlled saturable reactor: string in the circuit of the choke-type or self-saturation saturable reactor in the voltage sine wave cycle, the saturable reactor before saturation absorption of certain volt - seconds, reaching saturation, after it was full open state. Therefore, non-sinusoidal output voltage, this effect saturable reactor and thyristor similar. The main components of the electrical circuit of resistors, capacitors and inductors. Inductor current changes inhibit the role and enables alternating phase shift. The winding-type stationary induction apparatus having an inductance effect called reactor. |
