General Description:
Hai Bang JCZ3-24kV AC high-voltage vacuum contactors are newly developed by our company for 24KV system application, backed by our years of experience in design and technical power; either the appearance and the performance, reliability, applicability and easy-maintenance features are in line with requirements from customers.
Product Features
• Main Circuit
• International main-stream technology of epoxy integral molding for the insulation canister frame, which fully meets the insulation requirements stipulated in the State Standard.
• Use vacuum switch from domestic famous manufacturer, which features mature in technology, reliable in quality and with good market reputation.
• For grade 630A, use end-surface and conductive clamp dual-dynamic terminal connection, which features small in contact resistance, low in temperature rising and more reliable.
• Bus-bar either fine in appearance and durable, there are 2 choices for the static (upper) contact terminal: level and vertical connection ways, and at the same time, it is applicable to select the wire-exit whether of same or different directions for dynamic and static contact terminals, so as to be convenient for customers in use.
• Electromagnetic System
• Unique built-in large capacity sealed auxiliary switch compared with products alike greatly improves the reliability of the auxiliary switch in safety use.
• Optimizes action-structure, and that lowers activation and maintaining power of the coil, and hence with lower temperature rising, longer working life and better reliability.
• Limit buffer is set for moving armature breaker separating, which eliminates hidden trouble yielded from bounce of breaker separating. At the same time, the auxiliary switch punching also uses buffer and that lowers the impact force of action and promotes reliability of the auxiliary switch.
• Action Structure
• The flexible shaft bearing accepts force without catching, small in axial float and that promotes the performance and coherence of action.
• Reasonable action mechanism and moving end are of dual guiding mechanism, which can ensure the dynamic conductive rod in the vacuum tube.
