Review
The WVT-12(M) series of monolithic indoor high voltage vacuum circuit breakers with magnetic drive is a new generation of products developed by our company based on the concept of high reliability, long service life and ease of operation, by optimizing the design based on foreign technologies, and corresponds to the advanced domestic level. The magnetic drive used in them has such significant advantages as small dimensions, light weight, simplicity of design, reliable operation, no need for maintenance and long service life.
Mechanism
1. Optimized design layout ensures ergonomic operation and excellent performance.
2. Optimized design of each functional module makes daily monitoring and maintenance easier.
3. The use of surface treatment methods, including electrostatic powder coating of the case and galvanic nickel-phosphorus coating of up to 80% of the mechanism parts, guarantees both an attractive appearance and high internal quality.
4. The dynamic characteristics of the magnetic drive fully comply with the requirements of the dynamic characteristics of the vacuum arc chute, which ensures a mechanical life of up to 60,000 cycles.
5. Reliable manual tripping device ensures tripping operation at a speed similar to electrical tripping and is designed for use in emergency situations.
6. Perfect mechanical and electrical interlocks ensure a high level of product safety.
Main circuit
1. Adopts solid insulation design; Advanced monolithic epoxy casting technology seamlessly integrates the vacuum arc chute, current-carrying circuits and insulating supports into a single monolithic column (pole). This made it possible to fundamentally solve the problem of the resistance of the vacuum circuit breaker to the external environment, expand the scope of its application, and also provide the possibility of miniaturizing the product.
2. The use of unique R-shaped contacts ensures excellent switching performance when switching capacitive loads (capacitor banks).
3. The special soft shell technology of the vacuum arc chute further improves the insulating properties of the monolithic pole.
