Inside-Mounted Vacuum Circuit Breaker,SF6 Circuit Breaker

1. Overview of Inside-Mounted Vacuum Circuit Breaker,SF6 Circuit Breaker

VS1 side-mounted series indoor high-voltage vacuum circuit breakers are suitable for three-phase AC 50Hz, rated voltage 7.2~12kV indoor high-voltage switchgear. Used in ring network cabinet equipment, it can replace the sulfur hexafluoride load switch as the incoming switch of the substation and provide backup protection for the outgoing cabinet; at the same time, it can be used as the outgoing switch protection and control the distribution transformer with a capacity greater than 1250kVA It can also be used as a tie breaker for dual power supply lines.

VS1 side-mounted series indoor high voltage vacuum circuit breaker circuit breaker meets the national standard GB1984 "AC high voltage circuit breaker", JB3855 "3.6～40.5kV indoor AC high voltage vacuum circuit breaker", DL403 "10～35kV indoor high voltage vacuum circuit breaker" Ordering technical conditions" and relevant IEC standards, and have reliable interlocking functions.
VS1 side-mounted series indoor high-voltage vacuum circuit breakers can be operated frequently and have the ability to repeatedly break and quickly reclose.
VS1 side-mounted series indoor high-voltage vacuum circuit breakers are designed with front and rear sub-assembly structure, which can be used as a side-mounted fixed installation unit.

2. Structural features of Inside-Mounted Vacuum Circuit Breaker,SF6 Circuit Breaker

The circuit breaker adopts a three-pole structure, the primary conductive circuit can be equipped with insulating cylinders or solid-sealed poles, the phases are solid insulation, the overall size is small, the distance between phases is 210mm (the same as the SF6 load switch), and it is easy to install in XGN15-12 type In the high-voltage switchgear, the main bus can be shared with the SF6 load switchgear;
The operating mechanism is integrated with the circuit breaker, and the three-phase arc extinguishing chamber is arranged at the rear, center and front. The operating mechanism can be disassembled and installed in the whole machine, which is convenient for the maintenance of the operating mechanism and its auxiliary switches. The structure of the transmission system is simple. , There are few adjustment links, and the mechanical characteristic parameters of the arc extinguishing chamber are fully guaranteed. The mechanical life is up to 20,000 times. The circuit breaker has high reliability and minimal maintenance.
Vacuum, no pollution.
The vacuum interrupter adopts copper-chromium contact materials and a longitudinal magnetic field contact structure. It has the advantages of strong breaking capacity, high insulation strength, small interception value, light burnout, long electrical life, and maintenance-free during the entire working period.
Vacuum interrupters such as Siemens can be configured to meet the needs of special users.
