24kV Fixed Type SF6 Gas Circuit Breaker 630A Ckt Breaker with Insulated Cylinder for High Voltage Power Distribution

Technical Parameters of SF6 Gas Circuit Breaker

The circuit breaker’s pole, specifically the arc-extinguishing chamber, is a sealed system that requires no maintenance throughout its service life. Its sealing lifespan meets the requirements of IEC 62271-100 and CEI 17-1 standards.
The switching process (closing and opening) of the LYHM4 circuit breaker is performed by the REH type spring operating mechanism. The operating mechanism and the pole are fixed to the same metal frame, which also serves as a truck that can be pushed in and out along the rails inside the switchgear. The truck can be operated even when the cabinet door is closed.
The lightweight and compact structure of the circuit breaker ensures its durability and reliability.
The RCW series automatic recloser integrates control, protection, measurement, communication, fault detection, and on-line monitoring of switching operations.

Application Scope

The LYHM4 circuit breaker is suitable for control and protection of distribution lines, substations, distribution stations, motors, transformers, and capacitor banks.

With the use of SF6 automatic arc-quenching technology, the LYHM4 circuit breaker does not generate operating overvoltage, making it ideal for applications where the dielectric strength of insulating materials is particularly sensitive. It is especially suitable for capacitive and inductive load applications, such as capacitor banks, compensation reactors, and motors.
