Research on Reliability Enhancement Scheme Implementation for Modular Intelligent Prefabricated Substations
Research on Reliability Enhancement Scheme Implementation for Modular Intelligent Prefabricated Substations
1 Implementation Strategies for the Scheme1.1 Deepen Survey and ResearchBefore constructing prefabricated cabin - type substations, it is necessary to conduct detailed surveys of local working conditions, clarify the construction scale and objectives, evaluate existing power facilities, plan projects, make up for infrastructure shortcomings, and adjust the construction rhythm. Meanwhile, control costs to avoid project suspension.1.2 Strengthen Structural ConstructionDuring promotion, multi - dim

Comparative Analysis of 500 kV Prefabricated Substations vs. Conventional Substations
The secondary equipment area of conventional substations uses reinforced concrete or prefabricated steel structures, facing issues like long construction cycles, unreasonable functional zone design, strict environmental assessments, dust, noise, and disturbances. Primary and secondary equipment can only be installed after civil works and decoration, lowering construction efficiency.Prefabricated cabin substations integrate modularity, intelligence, and cost - effectiveness, boasting green, energ

Operational Analysis of Prefabricated Enclosure Substations in Extreme Cold Climate Applications
Under global climate diversity, alpine power construction faces technical and environmental challenges. Extreme climates, complex geology, and long - term low winter temperatures, along with ice, snow, and storms, strain electrical equipment stability and power facility construction (schedule, cost, maintenance). Traditional on - site substations, with long construction and poor adaptability, can’t meet alpine regions’ fast, stable power needs.Prefabricated cabin substations, as modu

Implementation of Precast Foundations for Ring-Main Unit Compact Substations in Grid Modernization Initiatives
Compact substation boxes, with advantages like safe operation, high reliability, and easy maintenance, are used in urban grid construction/renovation. Structurally divided into American - style (high - cost, noisy, low - efficiency, gradually phased out) and European - style (large - sized but more advantages, still popular).To address their pros/cons, ring - network prefabricated ones were developed.I.

Underground Power Cable Transmission LinesDirect - buried power cable lines have large ground - distributed capacitance, causing high single - phase - to - ground short - circuit capacitive current. For 10 kV lines, if this current exceeds 10 A, arcs hardly self - extinguish, risking arc overvoltage and endangering line equipment. Arc extinction is thus necessary. With a Dyn - connected main transformer, an arc - suppression coil on the secondary neutral point suffices. For Yd - connected ones,

Failure Analysis and Design Optimization of Conventional Grounding Transformers
I. Core Cause of Damage: Electrodynamic Impact (Complying with GB/T 1094.5 / IEC 60076-5)The direct cause of high-voltage winding end collapse is the instantaneous electrodynamic impact induced by short-circuit current. When a single-phase grounding fault occurs in the system (such as lightning overvoltage, insulation breakdown, etc.), the grounding transformer, as the fault current path, withstands high-amplitude and steep-rise-rate short-circuit currents. According to Ampère's force law
