This 126KV HV Outdoor high-voltage SF6 single-phase circuit breaker is suitable for use in 72.5KV and 126KV three-phase AC 50HZ transmission and transformation systems. Its primary purpose is to regulate and safeguard these systems, but it can also function as a contact breaker and opener group, offering versatility in its applications.

The 72.5KV Outdoor high-voltage SF6 ceramic column circuit breaker is designed for controlling and protecting 72.5KV transmission and transformation systems. It operates on a three-phase AC 50HZ outdoor high-voltage switchgear and can function and opener group. By utilizing the intelligent arc extinguishing principle of "thermal expansion+auxiliary blowing" and equipped with a CTB-1 operating mechanism, this circuit breaker meets the standards of GB1984-2003 and International Electrotechnical Commission standard IEC62271-100:2001 for High Voltage AC Circuit Breakers.

El tablero de distribución eléctrico de media tensión de alta corriente KYN28-12(Z) de CA de 7,2 KV 3150A está diseñado para su uso en sistemas de alimentación de CA trifásicos que funcionan a una tensión nominal de 12 kV y una frecuencia de 50 Hz. Este equipo se utiliza para recibir y distribuir energía eléctrica y al mismo tiempo administrar, proteger y supervisar los circuitos eléctricos.

The 12KV 1250AMP Vertical break two post isolating switch is specifically designed for use in 10(12,15,24)KV high voltage transmission and distribution lines. These switches serve the purpose of disconnecting and connecting single-phase or three-phase circuits without load and voltage. They are particularly engineered for single-phase application within a three-phase circuit system and are characterized by a simple and cost-effective design, ensuring ease of operation and maintenance. The switches are available in a range of rated current options, including 200400,600,630,800, and 1000,1250 amperes, providing the flexibility to select the most suitable option based on specific requirements. They are comprised of a base, pillar insulator, conductive part, and mechanism part.

The 40.5KV 1600A Outdoor high-voltage SF6 tank circuit breaker is a customized electrical switchgear designed to disconnect high-voltage electrical paths in emergency situations or for scheduled maintenance. It employs sulfur hexafluoride (SF6) gas as the medium to extinguish electrical arcs and provide insulation, which is safely confined within a sealed enclosure. This particular type of circuit breaker is purposely designed for exterior deployment in electrical substations and power transmission systems.

Gabinete de extinción de arco y eliminación de armónicos Durante el funcionamiento regular, el controlador del microordenador monitorea constantemente la señal de voltaje recibida del PT. Supongamos que el sistema experimenta una desconexión del PT, una conexión a tierra de metal monofásico o una conexión a tierra de arco monofásico. En ese caso, el voltaje del triángulo abierto secundario auxiliar cambiará rápidamente de un nivel bajo a un nivel alto. Entonces se activará el controlador del microordenador. Determinará el tipo y la discrepancia de fase en función de la alteración en el voltaje secundario del PT.
