Hv Disconnect Switch

 

 

 

Hv disconnect switches are AC 50Hz outdoor high-voltage electrical equipment with rated voltages of 10kV and 15kV. Outdoor high-voltage disconnectors are used to open and close high-voltage lines under no-load conditions and to electrically isolate high-voltage lines from energized electrical equipment such as high-voltage busbars and circuit breakers under maintenance. They can also be used to switch small capacitive or inductive currents. This series of outdoor disconnectors complies with relevant standards such as GB1985 "AC High-Voltage Disconnectors and Earthing Switches," IEC60129 "AC Disconnectors and Earthing Switches," and GB/T11022 "Common Technical Requirements for High-Voltage Switchgear and Controlgear Standards."

1. Distribution Line Protection: Suitable for 12kV overhead line branch protection, short-circuit current ≤ 12.5kA. Requires vertical installation (tilt angle ≤ 15°), with phase spacing ≥ 0.7m to prevent arc interference.

2. Transformer-Side Isolation: Serves as an isolation device on the high-voltage side of distribution transformers, used in conjunction with circuit breakers. Operation under load is strictly prohibited.

3. Special Environment Adaptation: Silicone rubber fused tubing (weather resistance ≥ 15 years) is recommended for highly polluted areas. For frequent operation, select a model with an M2 mechanical life rating.
