| 传统的中性点接地电阻柜只是一种纯硬件保护装置。随着科技的发展，现在的中性点接地电阻柜增加了智能控制部分。软件采用C语言和汇编语言，显示部分为大屏幕LCD汉字。智能控制单元可以在系统正常运行期间监控中性点的不平衡电流，电阻器，变压器和中性点接地电阻柜的温度;在单相接地故障期间，可记录接地电流，接地时间，电阻器温度，变压器和电阻柜。盖土网 防寒布 麻绳 油麻绳 麻刀 沥青麻绳 静压造型线 自动浇注机 铸铁拍门 钢制拍门 玻璃钢拍门保留更改和接地动作的数量以及通信接口，以及检测和记录的信息可以传输到主控室，以便操作员可以在第一时间获得信息。智能型发电机中性点接地电阻柜是一套完整的设备，设计用于发电厂发电机中性点的高阻接地。中性点接地电阻柜采用不锈钢或冷轧板，外形美观，耐腐蚀性强。发电机中性点接地电阻柜中的电阻器采用优质镍铬合金制造，安装在接地变压器的二次侧。它具备稳定的性能，耐高温和强大的流动能力。接地电阻器采用进口特种镍铬合金电阻，电阻器根据用户要求确定。机柜采用冷轧钢板制成，顶部通过壁衬套引出，或者从机柜底部取出电缆。中性点接地电阻柜配有干式单相接地变压器，电阻器，隔离开关，避雷器等电气设备，可方便地安装在发电机中性点附近。 The traditional neutral grounding resistance cabinet is only a pure hardware protection device. With the development of science and technology, the intelligent control part is added to the neutral grounding resistance cabinet. The software adopts C language and assembly language, and the display part is large screen LCD Chinese characters. The intelligent control unit can monitor the unbalanced current of neutral point, the temperature of resistor, transformer and neutral grounding resistance cabinet during the normal operation of the system; During single-phase grounding fault, the grounding current, grounding time, resistor temperature, transformer and resistance cabinet can be recorded. The number of reserved changes and grounding actions and communication interfaces, as well as the detected and recorded information can be transmitted to the main control room so that the operator can obtain the information at the first time. The intelligent generator neutral grounding resistance cabinet is a complete set of equipment, which is designed for high resistance grounding of generator neutral point in power plant. The neutral grounding resistance cabinet adopts stainless steel or cold rolled plate, which has beautiful appearance and strong corrosion resistance. The resistor in the generator neutral grounding resistor cabinet is made of high-quality nickel chromium alloy and installed on the secondary side of the grounding transformer. It has stable performance, high temperature resistance and strong flow ability. The grounding resistor adopts imported special nickel chromium alloy resistor, which is determined according to the user's requirements. The cabinet is made of cold-rolled steel plate, and the top is led out through the wall bushing, or the cable is taken out from the bottom of the cabinet. The neutral grounding resistance cabinet is equipped with dry-type single-phase grounding transformer, resistor, disconnector, lightning arrester and other electrical equipment, which can be conveniently installed near the neutral point of the generator. |
