  • Gas Circuit Breakers(GCB) : Transmission and Distribution

    Circuit breakers are vital equipment for protecting transmission systems. They cut off current instantly in the event of a system failure due to lightning or other issues. Hitachi is developing Gas Circuit Breakers (GCB) that work with high currents, with voltages from 110 kV to 550 kV, and accurately support increases in breaking capacity.

    The IEC 60480 directive also stipulates the limit values for the re-use of SF6 gas. It is absolutely necessary to know the gas quality before carrying out maintenance works on a circuit breaker in order to be able to decide on preparation, re-use or disposal of the SF6 gas. The essential quality criteria for SF6 gas in circuit breakers are as

    Aug 08, 2020The circuit breaker is the most critical part of a gas insulated substation system. The circuit breaker in a gas insulated system is metal-clad and utilises SF6 gas, both for insulation and fault interruption. The SF6 gas pressure in a circuit breaker is around 0.65 MPa. The circuit breaker is directly connected to either current
