VS1-12 vacuum circuit breaker’s overall structure is three-phase common tank type, with three-phase vacuum interrupter placed inside a metal tank. According to different insulation and protection methods, it is mainly divided into two structural types: ordinary type and pole type (solid-sealed type). The main conductive circuit of the ordinary type circuit breaker is set inside a cylindrical insulating tube made of insulating material, and the vacuum interrupter is placed in the insulating tube, which can effectively resist environmental influences and mechanical damage. The pole type adopts epoxy resin solid-sealing technology, integrating the vacuum interrupter, main conductive circuit and insulating support into a solid-sealed pole, which improves the environmental tolerance.
VS1-12 vacuum circuit breaker is designed with a front-back split structure, supporting multiple installation forms. It can be installed as a fixed unit in fixed switchgears (such as XGN type, GG-1A type), and can also be used as a withdrawable (cartridge type) unit in cooperation with a special chassis car, suitable for cartridge type switchgears such as KYN28 (GZS1) type. This product has certain interchangeability and universality. The main technical parameters of the VS1-12 vacuum circuit breaker include: rated voltage 12kV, rated frequency 50Hz. Rated current includes 630A, 1250A, 1600A, 2000A, 2500A, 3150A, 4000A, etc. Rated short-circuit breaking current includes 20kA, 25kA, 31.5kA, 40kA, etc. Rated short-circuit making current (peak value) includes 50kA, 63kA, 80kA, 100kA, etc. Rated peak withstand current (dynamic stability current) includes 50kA, 63kA, 80kA, 100kA, etc. Rated short-time withstand current (4s thermal stability current) includes 20kA, 25kA, 31.5kA, 40kA, etc. Rated insulation level includes power frequency withstand voltage for 1 minute: 42kV to ground, 48kV for the fracture; lightning impulse withstand voltage: 75kV to ground, 85kV for the fracture. Mechanical life is usually 20,000 or 30,000 times [3-4] [8] [11]. The breaking times of rated short-circuit breaking current are 30 or 50 times. The rated operation sequence is open-0.3s-close-open-180s-close-open.
The normal use environment conditions of the VS1-12 vacuum circuit breaker need to meet the following requirements: the upper limit of ambient air temperature is generally +40℃, the lower limit is -10℃ or -15℃, and it is allowed to be as low as -30℃ or -40℃ during storage and transportation. The altitude is not more than 1000m or 2000m; if a higher altitude is required, the rated insulation level needs to be increased accordingly. The daily average relative humidity is not more than 95%, and the monthly average is not more than 90%. The installation site should have no fire or explosion hazard, no severe pollution, chemical corrosion or violent vibration. The seismic intensity is not more than 8 degrees.、
