15KV-10KV Bus Tie Switchgear

Product Overview:The Bus Tie Switchgear is a critical component in medium-voltage (MV) power distribution systems, designed to interconnect and isolate multiple busbar sections. Rated for 10KV (IEC) to 15KV (ANSI) applications, it ensures load balancing, enhanced power continuity, and rapid system reconfiguration during faults or maintenance. Compliant with IEC 62271-200, GB 3906, and ANSI C37.20.2 standards, it is widely used in industrial, commercial, and utility networks.

Product Introduction Technical Parameter Size

1. Product Description 
        The Bus Tie Switchgear features a modular design, comprising busbar compartments, circuit breaker cells, cable chambers, and low-voltage control sections. Key components include:
Vacuum Circuit Breaker (VCB)
        Three-Position Switch (Disconnector/Earthing Switch)
        Current Transformers (CTs)
        Multifunction Protection Relay
        The enclosure is constructed from galvanized steel or Aluzinc, tested for internal arc resistance (IAC AFLR 40kA per IEC 62271-200). It supports IEC 61850 communication for SCADA integration and is widely deployed in data centers (Tier III/IV), oil & gas plants, and other critical facilities to minimize MTTR (Mean Time To Repair).

2. Product Functions 
        Redundant Power Supply: Automatic Transfer Switching (ATS) ensures uninterrupted power between dual sources.
        Fault Isolation: Differential protection (87B) or overcurrent protection (51/51V) trips faulted sections within 20ms.
        Load Balancing: Maintains ±5% load deviation between busbars for optimal efficiency.
        Safety Interlocks: Mechanical “Five-Prevention” interlocking (per NFPA 70E) prevents misoperation.
        Energy Monitoring: Embedded Class 0.5S metering with Modbus RTU/DNP3.0 protocols.

3. Product Configuration 
Primary Circuit
        Main busbars: TMY-100×10 copper with heat-shrink insulation.
        Breaker options: Permanent magnet (VS1) or spring-operated (VD4) mechanism.

Secondary System
        Standard microprocessor-based relay,with fault recording and GOOSE messaging.
        Optional wireless temperature sensors (TE Connectivity) or UHF partial discharge monitoring.

Environmental Adaptability
        High-altitude design (up to 4,000m).
        Anti-condensation heaters (auto-controlled).

4. Product Features 
        Compact Layout: Vertical segregation (per IEC 62271-200) reduces footprint by 30%.
        High Reliability: Vacuum interruption (chopping current <5A), 100 full-capacity breaking cycles.
        Smart Maintenance: AR-assisted inspection via NFC-tagged parameters.
        Eco-Friendly: SF6-free design, compliant with GGGP (Global Greenhouse Gas Protocol).
        Customization: Left/right cable entry, dual bus-tie topologies available.
