630AZW20 630A Outdoor Vacuum Circuit Breaker 11kV Auto Recloser
OCB2 series outdoor vacuum circuit breaker is used in three-phase power system of AC 50/60Hz, rated voltage 10-38kV, as breaking, closingload current. Also, the circuit breaker has the function of overload and short circuit protection, controlling, measuring, remote control and monitoring. It accords with the standards of IEC62271-100 & GB1984 AC high voltage circuit breaker, GB/T 11022 HV General technical requirement of switches and control apparatus.
OCB2 series outdoor high voltage vacuum circuit breaker is widely used. For the main section, close load current and short-circuit current, suitable for transformer substations and industrial and mining enterprises distribution systems to make protection, and control in more suitable to the frequent operation occasion of the power grid. This product and controller form a complete set, as a dividing line for power companies and users circuit breaker boundary first circuit breaker, have the full protection of the performance, excellent coincidence device function, meet the power distribution automation system requirements.
Features:
1. The OCB2 series outdoor pole-mounted HV vacuum Circuit Breaker applies three-phase pole-type structure. It has characteristics of stable closing/breaking property, no fire or explosion danger, maintenance-free, small dimension, small weight, long service life, etc.
2. The OCB2 series is hermetical sealed, and is moisture-resistant, anti-condensation. It is especially suitable for application at severe cold and damp areas. Three-phase pillar and current transformer apply imported outdoor epoxy resin solid insulation materials. It is high/low temperature resistant, UV-resistant and anti-ageing.
3. The operating mechanism is miniature spring operating mechanism with low breaking/closing energy consumption. The driving of it applies straight transmission with little components and high reliability. The operating mechanism is enclosed in a cabinet, and that makes it rust-resistant and more reliable.
4. The OCB2 series is are electrically and remote controlled, also can be manually controlled. They can be fitted with controllers to realize electric automation or to form auto-reclosing device with reclosing controller.
5. The OCB2 series is also fitted with disconnectors of clear isolation opening and have reliable mal-operation prevention mechanical interlocking device between CBS. And the disconnectors are easily detachable.
