变电站(所)在电源系统的工业企业是一个至关重要的因素。 他们接收,转换和发送电能。根据能源和需求,变电站分为中央配电变电站电压为110-500kV；主要降压变电所电压为110-220/6-10-35kV； 深入口变电站为110-330/6-10Kv；二次变电站的电压为6-10Kv；车间变电所电压为6-10/0.38-0.66kV。在主要的降压变电所,电源能量转化电压为110-220kV，通常使用6-10Kv(有时为35kV变电所)的电压分配给企业和被用来满足高压服务。
中央配电变电站从电力系统接收能量并分发它(不包括或者包括部分变换) 给企业不同区域，通过空中电缆和地下电缆线路电压为110-220kV。 中央分配变电站站不同于主配电变电它是一个更强大的电力设施,它的电压大部分在110-220kV的电压。它可以简化初级电压、中级电压或地区的开关电路。中低级别变电站改造能量来自6-10kv的电压,它的二次侧电压为380/220或660/380。
升压变压器变电站用于将电厂产生的能量转化使发电机产生的电压升高,从而有效地减少在远距离输电能量的损失转换器变电站的目的是为了将直流转换成交流(有时相反)和转换成能量时改变频率。转换器变电站的能量转换是用半导体整流器来变频的。带半导体整流器的转化器变电站是最经济的。6-10kV的配电变电站主要依据主配电变电站(有时依据中央配电变电站)。110-220kV变电站系统区域的划分时，根据变电站设备功能划分时是有学问的，6-10kV的变电站设备划分在变电站的入口。
Substations are a vital element in a power supply system of industrial enterprises．They serve to receive ，convert and distribute electric energy .Depending on power and purpose ,the substations are divided into central distribution substations for a voltage of 110-500kV;main step-down substations for110-220/6-10-35kV;deep entrance substations for 110-330/6-10Kv;distribution substations for 6-10Kv;shop transformer substations for 6-10/0.38-0.66kV.At the main step-down substations, the energy received from the power source is transformed from 110-220kV usually to 6-10kV(sometimes 35kV) which is distributed among substations of the enterprise and is fed to high-voltage services.
Central distribution substations receive energy from power systems and distribute it (without or with partial transformation) via aerial and cable lines of deep entrances at a voltage of 110-220kV over the enterprise territory .Central distribution substation differs from the main distribution substation in a higher power and in that bulk of its power is at a voltage of 110-220kV;it features simplified switching circuits at primary voltage; it is fed from the power to an individual object or region .Low-and medium-power shop substations transform energy from 6-10kV to a secondary voltage of 380/220 or 660/380.
