Description

Compact Prefabricated Substation detailed Introduction

he combined box-type substation, also known as a combined transformer or American-style box-type substation, is a high-performance Compact Prefabricated Substation and a core Combined Compact Prefabricated Substation serving as a critical power supply unit in cable-distributed power grids. This Combined Compact Prefabricated Substation features a highly integrated design that embeds high-voltage load switches and high-voltage fuses directly inside the transformer tank, realizing the organic combination of voltage conversion and high-voltage protection functions.

Its oil tank adopts a fully sealed structural design, and the built-in transformer oil provides excellent insulation and efficient heat dissipation performance for the whole equipment. As a professional Compact Prefabricated Substation, it boasts outstanding advantages such as compact size, light weight, convenient installation and maintenance, high safety and reliability, and an aesthetically pleasing appearance. It is widely applied in various outdoor power supply scenarios including urban central areas, residential communities, hotels and hospitals, industrial and mining enterprises, oil depots, airports, railways, and docks, perfectly meeting the medium and low-voltage power distribution needs of diverse urban and industrial scenarios.

Product Features of Compact Prefabricated Substation

Ultra-Compact Size, Space-Saving Layout:This Combined Compact Prefabricated Substation features an optimized integrated structure with an ultra-small footprint, occupying only about 1/3 to 1/5 of the area of domestic European-style box-type substations with the same capacity. The Compact Prefabricated Substation’s streamlined design maximizes space utilization, enabling flexible installation in narrow outdoor spaces such as community green belts, street side strips and industrial park auxiliary areas without occupying valuable land resources.
Fully Sealed & Insulated Structure, High Operational Safety:Adopting a fully sealed and fully insulated overall design, the Compact Prefabricated Substation requires no additional insulation distance between internal components, fundamentally eliminating electrical safety hazards such as electric leakage and short circuit. The Combined Compact Prefabricated Substation’s hermetic structure also effectively prevents dust, moisture and foreign matter intrusion, ensuring safe and reliable long-term operation in outdoor environments.
High-Performance Transformer, Excellent Electrical Performance:Equipped with an S11-type energy-saving transformer, the Combined Compact Prefabricated Substation features low power loss, low operating noise and strong overload capacity, effectively reducing energy consumption and environmental noise pollution. The Compact Prefabricated Substation is divided into three independent functional components: high-voltage compartment, low-voltage compartment and transformer, usually arranged in a scientific "pin" shape, which rationalizes the internal layout and improves the equipment's operational stability.
Flexible & Reliable Power Supply, Diverse Scenario Adaptation:The high-voltage side of the Compact Prefabricated Substation is configured with a V-type or T-type load switch plus two-stage fuse protection, forming a multi-level protection system. The Combined Compact Prefabricated Substation is compatible with both ring network and terminal power supply scenarios, and can be flexibly matched with different power grid wiring schemes, meeting the diverse power supply needs of urban power grids, industrial power systems and commercial power distribution networks.
Comprehensive Monitoring Components, Real-Time Operation Supervision:The high-voltage compartment of the Combined Compact Prefabricated Substation is fully equipped with professional monitoring components including oil level gauge, oil temperature gauge, pressure gauge, pressure relief valve and oil drain valve. These components realize real-time monitoring of the transformer's oil level, operating temperature and internal pressure, and the Compact Prefabricated Substation can timely release pressure and discharge oil in case of abnormal conditions, ensuring the safe and stable operation of the equipment.
Adaptable Inlet & Outlet Configuration, Customizable Functions:The high-voltage incoming line of the Compact Prefabricated Substation uses a high-reliability cable joint, and can be optionally configured with a zinc oxide arrester to enhance lightning protection performance. It fully meets various low-voltage feeder configuration requirements, and the Combined Compact Prefabricated Substation can add low-voltage metering devices and branch outgoing lines according to user actual needs, realizing personalized customization of power distribution functions.
