发电机是电力系统的原动力
发电机是电力系统的原动力,在运行中必须具备对突发性故障的应变能力,发电机中性点的接地方式与此有密切的关系。发电机中性点的接地方式有:中性点直接接地、中性点经低阻抗接地、中性点不接地、中性点经消弧线圈接地、中性点经高阻抗接地。在热力和电气性能上,能满足电力中性点对设备的要求,具有耐受温度高、电阻率高、电阻温度系数小 。
The generator is the original power of the power system, so it must have the ability to deal with sudden fault in operation. The grounding mode of the generator neutral point is closely related to this. The grounding methods of generator neutral point include: direct grounding of neutral point, low impedance grounding of neutral point, ungrounded neutral point, arc suppression coil grounding of neutral point and high impedance grounding of neutral point. In terms of thermal and electrical performance, it can meet the requirements of power neutral point for equipment, with high resistance temperature, high resistivity and small resistance temperature coefficient.
同时又具有抗拉强度高、韧性好等优良的机械性能,是0.4KV-35KV发电机组采用高阻接地的专用成套装置。中性点接地电阻柜已广泛应用于城市供电系统、电厂、地铁、冶金及石化等系统,积累了非常多的成功的运行经验,对于提高系统运行的可靠性、安全性具有良好的效果。特点:采用优质不锈钢材质不锈钢,电导率高,温度系数高,可耐1400℃的高温,耐腐蚀,稳定性好;柜内接地变压器采用干式变压器,容量大,耐冲击。
At the same time, it has high tensile strength, good toughness and other excellent mechanical properties. It is a special complete set of 0.4kv-35kv generator set with high resistance grounding. Neutral grounding resistance cabinet has been widely used in urban power supply system, power plant, subway, metallurgy and petrochemical systems, and has accumulated a lot of successful operation experience, which has a good effect on improving the reliability and safety of system operation. Features: high quality stainless steel, high conductivity, high temperature coefficient, high temperature resistance of 1400 ℃, corrosion resistance, good stability; grounding transformer in the cabinet adopts dry-type transformer, large capacity, impact resistanc
