The indoor vacuum circuit breaker ZN63 is also the VS1 vacuum circuit breaker that we often say. It is one of the important components commonly used in our high-voltage complete sets of equipment. So which cabinet types should it be used for? Which cabinet type is it suitable for?
Before answering this question, let us first understand what installation methods of ZN63 vacuum circuit breakers are available, and the size requirements of the complete set of equipment?
ZN63 vacuum circuit breaker has 4 installation methods:
1. ZN63 vacuum circuit breaker handcart type, which is composed of mechanism, arc extinguishing chamber, chassis car, contact, contact arm and other components.
2. ZN63 vacuum circuit breaker is fixed type, it is composed of mechanism, arc extinguishing chamber, and other components.
3. The side-mounted ZN63 vacuum circuit breaker is similar to the fixed type, except that the vacuum interrupter is installed vertically.
4. The ZN63 vacuum circuit breaker is hand-push type. It is similar to the handcart type, except that the chassis is different. This should be used in the market, and it is generally used in coal mines.
Then the complete set of equipment, for the size of the vacuum circuit breaker, the cabinet width is 450MM, 550MM, 650MM, 750MM, 800MM, 1000MM and so on.
Different sizes and widths are different. The general size of the central cabinet is 450MM, 550MM, 650MM, 800MM, 1000MM. These dimensions are generally mid-mounted switchgear. The model is KYN28A, and the ZN63 vacuum circuit breaker it is equipped with is a handcart type.
The fixed size is more, 450MM, 550MM, 650MM, 750MM (common size), 1000MM and so on. These dimensions are generally fixed switchgear models: HXNG15, HXGN17, GG1A, GGX, XGN2, etc. It can also be used in floor-standing metering switch cabinets.
Side-mounted vacuum circuit breakers are rarely used in switchgear cabinets with smaller cabinets. ZN63 hand-push vacuum circuit breaker is sometimes used in coal mine reconstruction.
