Parallel circuits are characterized by the fact that there are multiple pathways by which charge can travel from the + terminal to the - terminal. During any single loop of charge around a parallel circuit, the charge will pass through each resistor in the circuit. The overall resistance of a...
晶闸管投切电容器( Thysistor Controlled Capacitor-TSC)都是重要的无功补偿装置。 近年来出现的静止无功发生器(Static VAR Generator-SVG)、有源电力滤波器(Active Power Filter-APF)等新型电力电子装置具有更为优越的无功功率和谐波补偿(VAR and Harmonic Compensate)的性能。 在配电网系统,电力电子装置还可用于防止电...

PLC的外部设备主要是指控制系统中的输入输出设备,其中输人设备是对系统发出各种控制信号的主令电器,在编写控制程序时必须注意外部输入设备使用的是常开还是常闭触点,并以此为基础进行程序编制。否则易出现控制错误。 在PLC内部存储器中有专用于输入状态存储的输入继电器区,各输入设备(开关、按钮、行程开关或传感器信号)的...
