China SF6 Gas HV CB Manufacturer, Supplier, Factory

In recent years, the engineering construction landscape has evolved in response to societal, economic, and technological advancements. There is an increasing demand for compact, intelligent, and low-maintenance switch equipment. Domestic and international manufacturers are actively developing 40.5KV 3150A Medium Voltage Gis Gas Insulated Switchgear (C-GIS), which enclose high-voltage components like busbars, circuit breakers, isolating switches, and power cables within a pressure-reduced shell.

The CFB3 series miniature circuit breaker is suitable for overload and short circuit protection in AC 50/60Hz, rated voltage up to 230V/400V, and rated current up to 125A lines. It can also be used for infrequent on/off operations of the line under normal conditions. The CFB3-63 series circuit breaker is equipped with accessories such as CFB3-F auxiliary contacts, CFB3-FB auxiliary alarm contacts, CFB3-FL shunt release, CFB3-QY undervoltage release, CFB3-GY overvoltage release, CFB3-GQY overvoltage release, etc., providing convenience for the intelligent control of smart buildings. Overvoltage, undervoltage, and overvoltage/undervoltage are electronic release devices that are assembled and combined with circuit breakers or residual current circuit breakers. They are suitable for AC 50Hz/60Hz circuits with a rated voltage of 230V, and are used to protect against overvoltage, undervoltage, and overvoltage caused by line faults, avoiding damage to electrical equipment or inability to function properly due to fluctuations in grid voltage. The circuit breaker has an isolation function. Compliant with standards: GB/T10963.1, IEC60898-1, GB/T20645.

Arc extinction and harmonic elimination cabinet During regular functioning, the microcomputer controller constantly monitors the voltage signal received from PT. Suppose the system experiences PT disconnection, single-phase metal grounding, or single-phase arc grounding. In that case, the auxiliary secondary open triangle voltage will promptly shift from a low to a high level. The microcomputer controller will then activate. It will determine the type and phase discrepancy based on the alteration in the PT secondary voltage
