132kv Power Transformer FAQ
Q1: What is a 132kV power main transformer?
The 132kV main transformer is a power equipment with a rated voltage of 132kV, used for voltage conversion (boost or buck) in high-voltage power grids. The common capacity range is 10-200MVA, and the core components include high-voltage windings, iron cores, cooling systems, and insulation oil. It is suitable for key nodes in regional transmission networks.
Q2:What are the main application scenarios of 132kV transformers?
*Main power grid: connected to a 232kV/132kV/33kV multi-level transmission network.
*Power plant export: Boost the generator output to 132kV to reduce long-distance transmission losses.
*Heavy industry zone: provides high-voltage direct power supply for steel plants, refineries, etc.
*Urban hub substation: Reduce 132kV to 33kV or 11kV for urban distribution.
Q3:What winding structures are commonly used in 132kV transformers?
*Double winding: direct conversion between high voltage side (132kV) and low voltage side (such as 33kV or 11kV).
*Three winding: supports multiple voltage outputs (such as 132kV/66kV/11kV), used for complex power grid interconnection.
*Autotransformer: Used for similar voltage levels (such as 132kV/110kV), with small size but high insulation requirements.
Q4:How to choose the cooling method for a 132kV transformer?
*ONAN (oil immersed self cooling): small capacity transformer (<50MVA), low cost.
*OFAF (forced oil circulation air cooling): Medium to large capacity (50-200MVA), high heat dissipation efficiency.
*OFWF (forced oil circulation water cooling): For large capacity or high-temperature environments, a water cooling system is required.
Q5:What is the delivery cycle for 132kV power transformers?
*Standard model: 3 months (including design, production, and testing);
*Customized model: 4-6 months (such as special cooling methods, high impedance requirements, etc.);
*Urgent orders: can be shortened to 2 months (subject to urgent fees and affected by raw material supply).
Q6:What is the design lifespan of a 132kV power transformer in years?
*Theoretical lifespan: over 30 years (based on IEC standards);
*Actual lifespan: typically 50 years, significantly affected by load rate, maintenance level, and environmental factors such as humidity and pollution.
*Key to extending lifespan: regular oil chromatography analysis, control winding temperature ≤ 65 ℃, and avoid long-term overload.
Q7:What are the warranty terms for 132kV power transformers?
*Warranty period: usually 12-36 months after leaving the factory (subject to the contract);
*Scope: Includes manufacturing defects (such as winding short circuits, iron core failures), except for human damage, natural disasters, etc;
*Special terms: Fragile parts such as tap changers and bushings may have a separate warranty period (such as 1 year) agreed upon.
Q8:What are the after-sales services for 132kV power transformers?
*Basic services: installation guidance, debugging support, operation training;
*Regular maintenance: oil testing, preventive testing, status assessment reports;
*Emergency response: on-site troubleshooting (promised to arrive within 72 hours);
*Upgrade and renovation: Capacity increase, noise reduction, and intelligent transformation (installation of online monitoring system).
