Loadbreak switch is suitable for three-phase AC 50Hz, rated voltage 12kV ring network power supply or dual-radiation power supply system, used to switch and switch load current and overload current, and can also be used to switch and switch no-load long lines. No-load transformers and capacitor banks, etc. The series combination of load switch and current-limiting fuse can be used instead of circuit breaker. That is, the load switch is responsible for closing and breaking various load currents, and the current-limiting fuse is responsible for breaking larger overload current and short-circuit current.
1. Features: double fracture, three stations, rotary movable contact.
2. Good insulation performance. The load switch is sealed by the upper and lower shells made of epoxy resin, filled with 0.045mpa pressure SF6 gas, and the main circuit and grounding circuit system are all placed in the shell.
3. The safety performance is good. If there is an internal arc, there is a structural weak point at the rear of the shell, which will be flushed, and then the arc relief valve on the cabinet will be flushed and the overpressure airflow will be directed outside the cabinet.
4. Both manual and electric operation are possible, and the operation is convenient and reliable.
Three-phase integral installation, good periodicity, few parts, convenient adjustment and installation, simple and easy. Maintenance-free and long life.
