Toshiba provides advanced, high-reliability substation equipment (switchgears, transformers, and gas-insulated switchgears - GIS) aimed at ensuring structural integrity and safety in high-voltage transmission, particularly in India's power grid. Their solutions focus on minimizing footprint, reducing maintenance, and adhering to strict international standards for safety and performance. 東芝 東芝 +4 Structural Integrity Features Gas Insulated Switchgears (GIS): Toshiba’s GIS are designed to withstand harsh environments (salty, sandy, humid) and are housed in earthed metal tanks, ensuring structural soundness and safety. Transformer Reliability: Toshiba has enhanced production for ultra-high voltage (UHV) transformers (up to 1200 kV) with a focus on, and rigorous design reviews to ensure, structural, electrical, and thermal reliability. Compact Design: The use of GIS allows for smaller, more rigid structures that are ideal for restricted spaces, reducing the overall structural footprint. Quality Control: TTDI (Toshiba Transmission & Distribution Systems India) implements strict ISO9001, Japanese Kaizen (continuous improvement), and in-house quality control methods for all structural and electrical components. 東芝 東芝 +4 Safety Precautions and Protocols Digital Substation Safety: Toshiba’s Process Bus technology reduces copper cabling, digitizing connections between primary and secondary equipment. This separation significantly improves safety for personnel in control rooms. Personnel Protection: Safety is maintained by using GIS to keep live parts inaccessible, reducing the risk to maintenance staff. Fire Safety: Introduction of natural ester oil-immersed transformers, which have fire points exceeding 300°C, reduces fire hazards compared to traditional mineral oil. Operational Safety Measures: Clearance and Height: Adherence to safety standards, including minimum heights (e.g., 4 meters) for live parts. Grounding: All metal structures and equipment tanks are connected to a grounding grid to prevent step and touch potentials. Access Control: Strict, unauthorized-access-restricted, and monitored access to high-voltage areas. PPE: Mandatory use of arc-rated clothing, insulating gloves, and safety gear. Fire Suppression: Automated fire protection systems in control rooms and for transformer equipment. Cybersecurity: Implementation of IEC 61850-8-1/9-2 and IEC 62351 standards to secure digital control systems against unauthorized access and cyber attacks. 東芝 東芝 +9 Design and Maintenance Standards ISO 45001: Toshiba adheres to strict ISO 45001 standards for Occupational Health and Safety Management (OHSMS), conducting risk assessments to prevent, eradicate, and mitigate accidents. Comprehensive Testing: Rigorous design reviews and testing, such as those by DNV-GL for communication components, are applied. Environmental Controls: Proper ventilation and air conditioning for equipment rooms to manage temperature and environmental factors, protecting the structural integrity of internal equipment. 東芝 東芝 +4 Key Safety Practices for Staff Lockout/Tagout (LOTO): Ensuring all equipment is de-energized before maintenance. Training: Regular training on high-voltage hazards and emergency evacuation procedures. Routine Inspection: Frequent inspections of structural integrity and safety equipment to ensure compliance with standards.
