Basics Guide To Prefabricated Substation

Prefabricated substations, resembling small houses, are integral to urban infrastructure, strategically placed along roadsides, in communities, and parks. They house essential power equipment tailored to meet diverse operational needs.

Types of Prefabricated Substations

Prefabricated substations typically consist of three main components: high-voltage switchgear, transformers, and low-voltage power distribution equipment. They are broadly categorized into two types: pad mounted transformer and compact transformer.

Pad Mounted Transformer

Pad mounted transformer integrates the transformer body, high-voltage load switch,current limiting fuse, tap changer, and other components within a single enclosure. This compact design ensures enhanced safety, reliability, and ease of installation. Key components include:

• High Voltage Bushing: Ensures safe connection for cables and insulated arresters.
• Fuse : Incorporates Bay-O-Net and current limiting fuse to protect against faults.
• Load Break Switch: Allows for load breaking and closing operations, crucial for operational flexibility.
• Transformer Tank: Houses the transformer core , featuring a fully sealed structure.

Compact Transformer

A compact transformer features a modular design where high-voltage switchgear, transformers, and low-voltage power distribution equipment are housed in separate rooms. This arrangement allows for flexible configuration and customization based on specific application requirements. Key features include:

• Flexible Layout: Can be configured as "mu" or "pin" types, optimizing space and operational efficiency.
• Application Versatility: Suitable for diverse environments including oil fields, high-rise buildings, and residential areas.
• Enclosure Options: Available in materials such as metal and non-metal, offering varying levels of protection and aesthetic integration.

Key Differences Between Pad Mounted Transformer and Compact Transformer

• High-Voltage Configuration: Pad mounted transformers integrate high-voltage components within the transformer tank, whereas compact transformers require a separate high-voltage cabinet.

• Customization Flexibility: Compact transformers offer more customization options for high-voltage, transformer, and low-voltage configurations compared to pad mounted transformers.

• Transformer Types: Pad mounted transformers typically use oil-filled transformers, while compact transformers can accommodate both oil filled and dry type transformers.

• Size and Cost: Pad mounted transformers are more compact and cost-effective than compact transformers, making them suitable for diverse urban applications.
