This design prevents accidental or unintended closure of the circuit breaker. Additionally, it includes an anti-jump function, which ensures that the circuit breaker remains in a stable closed position, reducing the risk of sudden tripping due to external factors.
5.Fault Discrimination with Zero-Sequence Current: The ZW32-12 electrical sectionalizer is equipped with the ability to distinguish between in-zone and out-of-zone faults using zero-sequence current analysis. This allows for accurate fault discrimination, enabling faster and more precise fault isolation and minimizing the impact on the power system.
6.Remote Control Switch for Misoperation Prevention: The ZW32-12 electrical sectionalizer incorporates a remote control switch with a specific design to prevent misoperations. This feature ensures that remote operations are carried out safely and reduces the risk of accidental tripping or unintended actions.
Structure:
1.Vacuum Interrupter: The vacuum interrupter is the core component of the circuit breaker. It is a sealed chamber that contains contacts and utilizes a vacuum to extinguish the arc produced during circuit interruption. The vacuum interrupter provides reliable and efficient breaking and making of electrical circuits.
2.Operating Mechanism: The operating mechanism is responsible for opening and closing the contacts of the circuit breaker. It typically includes a spring mechanism, operating rods, and associated linkages. 3.The operating mechanism can be manual or motorized, depending on the specific model of the circuit breaker.
4.Control Panel: The control panel houses the control and monitoring devices for the circuit breaker. It includes control switches, indicators, and protection relays. The control panel allows for manual control of the circuit breaker, as well as monitoring its status and protection functions.
5.Insulation System: The insulation system of the ZW32-12 vacuum circuit breaker ensures the electrical insulation between the live parts and the grounded components. It includes insulation materials, such as insulating bushings, insulating barriers, and insulation supports, to prevent electrical arcing and ensure the safe operation of the circuit breaker.
6.Enclosure: The circuit breaker is housed in an enclosure, which provides mechanical protection and environmental isolation. The enclosure is typically made of high-quality materials, such as metal or composite materials, to ensure durability and protection against external influences.
7.Auxiliary Contacts: The ZW32-12 vacuum circuit breaker may include auxiliary contacts for auxiliary control and signaling purposes. These contacts can be used for remote indication, control circuits, or interlocking with other equipment.
