　　Core Functions:

　　Used for connecting and disconnecting medium- and high-voltage circuits (such as motor starting, transformer switching, and capacitor bank control).

　　Vacuum arc extinguishing technology ensures high reliability and long life, suitable for frequent operation.

　　Structural Features

　　Vacuum Arc Extinguishing Technology

　　Arc Extinguishing Principle: Utilizing vacuum as the arc extinguishing medium, the arc rapidly dissipates and is absorbed by the vacuum environment when the contacts separate, achieving rapid arc extinguishing.

　　Advantages:

　　Short arc extinguishing time, reduced contact wear, and extended service life.

　　No arc spatter, high safety, suitable for flammable and explosive environments.

　　Low maintenance cost, no need for regular arc extinguishing medium replacement.

　　Insulation Design:

　　Epoxy resin cast insulation is moisture- and dust-resistant, suitable for harsh environments.

　　Complies with IEC 62271-100 standards, ensuring reliable insulation performance.

　　Operating Mechanism:

　　Electromagnetic operating mechanism with fast response (<50 ms closing time).

　　Supports remote control (via auxiliary contacts or communication interface).

　　3. Safety Performance

　　Built-in Protection:

　　Overvoltage protection (used with a lightning arrester).

　　Anti-malfunction design (mechanical interlock, electrical interlock).

　　Compliant Standards:

　　IEC 62271-102 (Special Standard for Vacuum Contactors).

　　GB/T 14808 (Chinese National Standard).

　　4. Energy Saving and Environmental Protection

　　Low Energy Consumption: The operating mechanism consumes low power, in line with green energy conservation trends.

　　Pollution-Free: Vacuum arc extinguishing emits no harmful gases, ensuring environmental compliance.

　　Typical Application Scenarios

　　Motor Control:

　　Frequent starting/stopping of medium- and high-voltage motors (such as compressors, fans, and pumps).

　　Transformer Switching:

　　No-load switching of transformers in distribution systems to reduce inrush current.

　　Capacitor Bank Control:

　　Switching reactive power compensation devices to improve power factor.

　　Renewable Energy:

　　Circuit control for photovoltaic inverters and wind turbine converters.

　　Installation and Maintenance

　　1. Installation Requirements

　　Environmental Conditions:

　　Temperature: -25°C to +40°C (outdoor models require protection against condensation).

　　Altitude: ≤ 2000 m (derating required for higher altitudes).

　　Mechanical Installation:

　　Vertical installation, tilt angle ≤ 5°.

　　Ensure adequate ventilation to avoid local overheating.

　　2. Maintenance Cycle

　　Daily Inspection:

　　External appearance free of damage, and connecting bolts free of looseness.

　　Operating mechanism smooth and free of sticking.

　　Regular Maintenance:

　　Check the vacuum level of the vacuum interrupter every 5 years.

　　Replace contacts every 10 years.
