500 kV Dry-Type Shunt Reactor na gane mafi yawan takalmi da suka zama muhimmanci baki daya

Bayanan:

Shunt reactors naa konektado sa parallel configuration ha power system aron makompensahan an capacitive reactive power han transmission ug distribution systems. Ini nagpapahimo nga ang mga operating voltages mahimong mapabilin ha acceptable operating levels.

An shunt reactors ginbuhat bilang "Oil-Immersed" o "Dry-Type".

An Dry-Type reactors nakaconsist tikang han encapsulated windings, suportado ha appropriate insulators.

Katangian:

• Especial “Modular” Design na mas compact.

•  Maayo nga voltage equalizing performance, excellent tolerance ha transient overvoltage.

•  Wala iron core, low vibration, low noise.

•  Tungod ra nga 20% han weight han oil reactor, mas kaunti nga occupation ha lupa, completely replace an oil reactor, maintenance-free.

•  Low heat generation, rain proof, bird proof, maayo nga weather resistance ug mas reliable.

•  Easy assembly ug disassembly, fast ug convenient transportation, great anti-seismic structure.

•  Nagpapalit ha Oil-Immersed shunt reactors ug traditional Dry-Type Shunt Reactors.

Limiting Overvoltage:

• Ha weak electrical systems, kon an short-circuit power is relatively low, an voltage increases tungod ha capacitive generation. Kon an network's short-circuit power increases, an magnitude han voltage increase decreases, thereby reducing an need for compensation to limit overvoltage.

Limiting Reactive Power Transfer:

• An reactors makakamit hin reactive power balance across different parts han network. Ini is especially important ha heavily loaded networks kung di maaari magconstruct hin new lines tungod ha environmental reasons. An reactors used for this purpose are mostly thyristor-controlled to rapidly adapt to an required reactive power. For instance, ha industrial areas ha arc furnaces, an reactive power demand fluctuates between each half-cycle. Typically, a combination of Thyristor-Controlled Reactors (TCR) ug Thyristor-Switched Capacitor banks (TSC) is used to absorb ug generate reactive power based on instantaneous demand.

Extinguishing Secondary Arcs:

• Ha single-phase reclosing ha long transmission lines, an interphase capacitive coupling makapagprovido hin current nga sustains an arc, known as an secondary arc. By adding a single-phase reactor at an neutral point, an secondary arc can be extinguished, improving an success rate han single-phase automatic reclosing.
