Series reactor is mainly used to limit the short-circuit current, but also in series or parallel with capacitor in the filter to limit the high-order harmonics in the power grid. The reactors in 220kV, 110KV, 35kV and 10kV power grids are used to absorb the charging capacitive reactive power of cable lines. The operating voltage can be adjusted by adjusting the number of shunt reactors. UHV shunt reactor has many functions to improve the reactive power related operation of power system, mainly including: 1. Capacitance effect on light no-load or light load lines to reduce power frequency transient overvoltage; 2. Improve the voltage distribution of long transmission lines; 3. In order to prevent the unreasonable flow of reactive power and reduce the power loss on the line, the reactive power in the light load line should be balanced locally as much as possible; 4. Reduce the power frequency steady-state voltage on the high-voltage bus when the large unit is paralleled with the system, so as to facilitate the synchronous paralleling of the generator; 5. Prevent possible self excitation resonance of generator with long line; Reactor (Figure 5) Reactor (Figure 5) 6. When the neutral point of the reactor is connected to the small reactance grounding device, the small reactor can also be used to compensate the phase to phase and phase to ground capacitance of the line, so as to accelerate the automatic extinction of the potential supply current and facilitate the use. The connection of reactor is divided into series connection and parallel connection. The series reactor is usually used for current limiting and the shunt reactor is often used for reactive power compensation. 公司简介: 上海蜀乾自动化设备有限公司是西门子一级代理商,是西门子自动化与驱动集团认证的西门子数控系统、伺服驱动的第三方合作伙伴。 公司代理全系列西门子数控系统,伺服驱动电机,变频器,直流调速装置,软启动器、触摸屏,可编程控制器等产品的销售,同时提供零部件维修、电柜设计、PLC编程调试及普通机床和加工中心的数控改造等增值服务。产品广泛适用于车、铣、磨、刨、钻等金属切削机床和各类**机床设备及钢铁、重工、机械、**、造船、电子、电机、制药、医疗、纺织、印刷、轻工、包装、广告媒体等领域,同时配备完善的售后服务及过程监控.为各行业用户提供*的高效服务,为用户带来更多效益是我们的目标!我们期待着与您合作。
