▁ 产品概述 /Product overview

三相油浸式励磁变压器是一种专门为发电机励磁系统提供三相交流励磁源的装置，励磁系统通过可控硅将三相电源转化为发电机转子直流
电源，形成发电机励磁磁场，通过励磁系统调节可控硅触发角，达到调节发电机端电压和无功的目的。
发电机用励磁变压器的安全、稳定运行、是自并励机组安全、稳定运行的前台，是发电机组稳定发电、满负荷发电的先决条件，是励磁系
统可靠运行的关键。
该型变压器具有过载能力强、局放低、抗短路能力强、阻燃、低噪音可有效抑制高次谐波对变压器的影响等特点。

优点：采用波纹油箱，密封式结构，不漏油，免维护，比环氧变压器省 35% 成本。
用途：适用于水力发电厂和火力发电厂的静态励磁系统 。
Three-phase oil-immersed transformer excitation is a specifically for generator excitation system for three-phase ac excitation source device,
through the thyristor excitation system generator rotor dc power supply, three-phase power supply can be converted to form the generator
excitation magnetic field, through adjust the thyristor trigger Angle of excitation system, to achieve the purpose of adjusting the generator
terminal voltage and reactive power.
The safe and stable operation of excitation transformer for generator is the foreground of safe and stable operation of self-excitation unit, the
prerequisite of stable and full-load generation of generator set, and the key to reliable operation of excitation system.
The transformer has the characteristics of strong overload capacity, low local discharge, strong short-circuit resistance, flame retardant and low
noise, which can effectively restrain the influence of higher harmonics on the transformer.
Advantages: corrugated oil tank, sealed structure, no oil leakage, maintenance-free, 35% less cost than epoxy transformer.
Purpose: suitable for static excitation system of hydraulic power plant and thermal power plant.
