Product advantage
Modularize
1.The gear-driven modular spring mechanism with consistent magnitude and current has more stable operation;
2.the modular mechanism is convenient to disassemble and assemble, the closing and opening coils and the energy storage motor are convenient to replace, and the operation and maintenance are convenient;
3.The energy storage handle integrated on the panel is convenient and simple to operate.
Coil burn prevention
With anti-burning protection function of closing and opening coil, the operation and maintenance cost is reduced;
High-performance solid sealing pole
1.the use of tailor-made special vacuum interrupter;
2.Channels are reserved on both sides of the pole to realize air circulation and heat dissipation.
High reliability
1.30 times of electrical life and 30,000 times of mechanical life, providing customers with additional value-added services;
2.the whole series of closing bounce is less than 2ms, which improves the stability of the power grid and reduces the contact burning loss;
3.The energy storage travel switch with independent 1K1B contact, and the control circuit runs normally.
It's really safe
1.The main circuit of the whole system adopts soft connection mode to reduce resistance and fever;
2.Electric cabinet entry scheme to realize remote operation or unattended operation;
3.Suit cabinets with widths of 1000 and 800, and bring more choices to customers.
Product application
1.Construction industry (public, commercial buildings, real estate, etc.);
2.Industrial fields (petroleum, chemical industry, steel, coal mine, metallurgy, etc.);
3.New energy power generation;
4.Power grid system.
