YB-12 series box-type substation refer to high-voltage electrical equipment and transformers. Low voltage electrical equipment is combined into a compact complete set of distribution equipment. Used for high-rise buildings in cities, urban and rural buildings, residential areas, high-tech development zones, small and medium-sized factories, and mines. Oil fields and temporary construction sites are used for receiving and distributing electrical energy in the distribution system.
box-type substation have the characteristics of strong completeness, small size, compact structure, safe and reliable operation, easy maintenance, and mobility. Compared to conventional indoor substations. A box type substation with the same capacity usually occupies only 1/10 "1/5 of a conventional substation, greatly reducing the design and construction workload, and reducing construction costs. It can also be used for dual power and radiation terminal distribution systems, and is a new type of complete equipment for the construction and renovation of urban and rural substations.
YB Box type Substation comply with the standards of SD320-92 "Technical Conditions for Box type Substations" and ZBK4001-89 "Modular Substations".
The YB-12 Series box-type substation: A Comprehensive Overview
Introduction
The YB-12 series box-type substation is a compact, integrated power distribution solution widely used in urban and rural power grids, industrial parks, and renewable energy systems. Combining High-voltage switchgear, transformers, and low-voltage distribution equipment into a single prefabricated enclosure, it offers efficiency, reliability, and space-saving advantages. This article explores the design, features, applications, and benefits of the YB-12 series box-type substation.
1. Design and Structure
The YB-12 series box-type substation is designed with modularity and durability in mind. Its structure typically consists of three main compartments:
1. High-Voltage Compartment
Equipped with vacuum circuit breakers or load switches for safe operation.
Features SF6 insulation or solid insulation for enhanced safety and reduced maintenance.
Supports ring main unit (RMU) configurations for grid flexibility.
2. Transformer Compartment
Houses oil-immersed or dry-type transformers with capacities ranging from 100 kVA to 1600 kVA.
Designed for efficient heat dissipation and noise reduction.
Complies with IEC and IEEE standards for performance and safety.
3. Low-Voltage Compartment
Includes circuit breakers, meters, and protection devices for power distribution.
Supports smart monitoring systems for remote control and data collection.
The enclosure is constructed from corrosion-resistant materials (e.g., stainless steel or galvanized steel) and features weatherproofing for outdoor use.
2. Key Features
The YB-12 series box-type substation stands out due to the following features:
Compact Design: Saves space compared to traditional substations, ideal for densely populated areas.
Plug-and-Play Installation: Pre-assembled components reduce on-site construction time.
Energy Efficiency: Low no-load losses and high transformer efficiency (up to 99%).
Safety: Flame-retardant materials, mechanical interlocks, and fault alarms ensure operator safety.
Smart Compatibility: Supports IoT integration for real-time monitoring and predictive maintenance.
3. Applications
The versatility of the YB-12 series makes it suitable for diverse scenarios:
Urban Power Networks: Deployed in residential complexes, hospitals, and commercial centers.
Industrial Facilities: Provides stable power for manufacturing plants and mining operations.
Renewable Energy: Integrates with solar/wind farms for grid connection.
Temporary Power: Used in construction sites or emergency power supply.
4. Advantages Over Conventional Substations
1. Cost-Effective: Lower installation and maintenance costs due to prefabrication.
2. Scalability: Modular design allows for easy capacity upgrades.
3. Environmental Resilience: Operates in temperatures from -40°C to 45°C and withstands harsh weather.
4. Reduced Footprint: Occupies 30–50% less space than traditional setups.
5. Technical Specifications
Rated Voltage: 10/0.4 kV or 35/0.4 kV.
Transformer Types: Oil-immersed (ONAN) or dry-type (SCB).
Protection Class: IP34 or higher for dust and water resistance.
Standards Compliance: IEC 61330, GB/T 17467, and ANSI C57.12.
6. Maintenance and Lifespan
Routine inspections include:
Checking oil levels (for oil-immersed transformers).
Testing insulation resistance.
Cleaning ventilation systems.
With proper maintenance, the YB-12 series can operate reliably for over 20 years.
7. Future Trends
As smart grids evolve, the YB-12 series is expected to incorporate:
AI-driven diagnostics.
Bidirectional power flow for renewable integration.
Enhanced cybersecurity for IoT connectivity.
The YB-12 series box-type substation represents a modern, efficient solution for power distribution challenges. Its compact design, robust performance, and adaptability make it a preferred choice across industries. As energy demands grow, innovations in this technology will further solidify its role in global electrification.
