PM645BPM645B工控产品芯片封装的内部连接
工控产品封装引脚与PCB的连接。典型连接器IC插座。
印制电路与导线或印制板的连接。典型连接器为印制电路连接器。
底板与底板的连接。典型连接器为机柜式连接器。
设备与设备之间的连接。典型产品为圆形连接器。
接触电阻高质量的电连接器应当具有低而稳定的接触电阻。连接器的接触电阻从几毫欧到数十毫欧不等。
绝缘电阻衡量电连接器接触件之间和接触件与外壳之间绝缘性能的指标，其数量级为数百兆欧至数千兆欧不等。
抗电强度或称耐电压、介质耐压，是表征连接器接触件之间或接触件与外壳之间耐受额定试验电压的能力。

组合式电流电压互感器。组合式互感器由电流互感器和电压互感器组合而成，多安装于高压计量箱、柜，用作计量电能或用作用电设备继电保护装置的电源。组合式电流电压互感器是将两台或三台电流互感器的一次、二次绕组及铁心和电压互感器的一、二次绕组及铁心，固定在钢体构架上，浸入装有变压器油的箱体内，其一、二次绕组出线均引出，接在箱体外的高、低压瓷瓶上，形成绝缘、封闭的整体。一次侧与供电线路连接，二次侧与计量装置或继电保护装置连接。根据不同的需要，组合式电流电压互感器分为V/V接线和Y/Y接线两种，以计量三相负荷平衡或不平衡时的电能。
电力系统为了传输电能，往往采用交流电压、大电流回路把电力送往用户，无法用仪表进行直接测量。互感器的作用，就是将交流电压和大电流按比例降到可以用仪表直接测量的数值，便于仪表直接测量，同时为继电保护和自动装置提供电源。电力系统用互感器是将电网高电压、大电流的信息传递到低电压、小电流二次侧的计量、测量仪表及继电保护、自动装置的一种特殊变压器，是一次系统和二次系统的联络元件，其一次绕组接入电网，二次绕组分别与测量仪表、保护装置等互相连接。互感器与测量仪表和计量装置配合，可以测量一次系统的电压、电流和电能；与继电保护和自动装置配合，可以构成对电网各种故障的电气保护和自动控制。互感器性能的好坏，直接
影响到电力系统测量、计量的准确性和继电器保护装置动作的可靠性。
