2KV 24KV outdoor high voltage vacuum circuit breaker with disconnector

The ZW32-12 outdoor high voltage vacuum circuit breaker with disconnector is a reliable and efficient outdoor high voltage distribution equipment. It is designed for the interruption and closing of load current, overload current, and short circuit current in power systems. It is suitable for use in substations and industrial and mining enterprises' distribution systems for protection and control. Moreover, it is particularly suitable for urban and rural power grid construction and renovation, as well as places that require frequent operations.

Equipped with a spring-stored energy operating mechanism, the ZW32 vacuum circuit breaker can be operated manually, electrically, or remotely for opening and closing operations. It can also be combined with an isolating switch on the side of the circuit breaker to form an outdoor high voltage combination of a vacuum circuit breaker and an outdoor high voltage isolating switch, providing a visible isolation gap and reliable interlocking operation. Based on user requirements, it can be paired with a corresponding controller to form an AC high voltage vacuum automatic recloser or automatic sectionalizer with its own operating power, establishing an ideal device for achieving distribution grid automation. The high voltage voltage transformer can be installed externally, allowing for either integrated or separate installation.

The ZW32-12G/1250-20 and ZW32-12 series column-type outdoor high voltage vacuum circuit breakers are suitable for 12kV rated voltage and three-phase 50Hz outdoor high voltage switchgear. They are capable of interrupting and closing load current, overload current, and short circuit current in urban or rural distribution systems. The circuit breaker features a new and compact design with a fully enclosed structure and unique arc extinguishing chamber encapsulation technology, ensuring excellent sealing performance, moisture resistance, and anti-condensation properties. Consequently, it is suitable for use in high-temperature and humid regions.

The ZW32-12G circuit breaker with disconnector is composed of two major parts: the ZW32 circuit breaker and the isolating switch. It is designed to be used in various environmental conditions. Its specifications include an altitude of no more than 2000m, ambient air temperature ranging from -40℃ to +30℃, wind pressure not exceeding 700Pa (equivalent to a wind speed of 34m/s), no significant recurring vibrations, and a level of protection against pollution class III.

Key features of the ZW32-12 outdoor high voltage vacuum circuit breaker with disconnector include a three-phase column-type structure that ensures stable and reliable interruption performance, as well as no combustion or explosion risks, low maintenance requirements, small size, light weight, and long lifespan. The fully enclosed structure enhances sealing performance and helps improve moisture resistance and anti-condensation properties, making it particularly suitable for use in extremely cold or humid regions. The three-phase column and current transformers are made of imported outdoor epoxy resin solid insulation or user-requested insulation materials, such as epoxy resin and silicone rubber, providing high temperature resistance, UV resistance, and aging resistance capabilities.

The operating mechanism adopts a compact spring-operated mechanism with a low power consumption motor for opening and closing operations. The mechanical transmission follows a true dynamic transmission method, resulting in fewer components and high reliability. The operating mechanism is located inside a sealed mechanism box, which solves the problem of rust corrosion and improves reliability.

The circuit breaker can be operated manually, electrically, or remotely for opening and closing operations. It can be paired with an intelligent controller to achieve distribution automation or combined with a reclosure or sectionalizer controller to form an automatic recloser or sectionalizer. Additionally, it can accommodate two or three-phase current transformers for overcurrent or short circuit protection purposes and also provide current acquisition signals for intelligent controllers. Depending on user requirements, metering current transformers can be added.

The circuit breaker can be equipped with a three-phase interlocking isolating switch that features a visible gap when in the open position. It is equipped with a reliable anti-misoperation interlocking device between the isolating switch and the circuit breaker, ensuring that the circuit breaker can only be operated when the isolating switch is fully open or fully closed. Furthermore, it can be combined with surge arrester pillar insulators for convenient maintenance.

In summary, the ZW32-12 outdoor high voltage vacuum circuit breaker with disconnector is a technologically advanced and versatile device that meets the needs of modern power distribution systems. Its compact design, excellent sealing performance, resilient insulation materials, efficient operating mechanism, and compatibility with a range of controllers make it an ideal choice for achieving automation in distribution grids. With its ability to withstand harsh environmental conditions, it is well-suited for both urban and rural settings.
