摘　　要：深入剖析PASS开关接地刀闸合闸的闭锁功能,在此基础上设计出以MSP430F2012单片机和AD623仪表放大器为主体的智能高压带电传感器,同时配合能精确感应高压导体带电状态信息的高压传感探头,实现可控制闭锁功率继电器的触点状态及接地刀闸的带电闭锁功能。该传感器结构具有简单、体积小等特点,在不改变现有PASS主体结构的情况下,可有效解决原有技术存在的设备造价昂贵、功能过剩问题。The author analyzes the PASS switch grounding switch closing latching function, based on the design of the intelligent high voltage sensor based on MSP430F2012 microcontroller and AD623 instrumentation amplifier as the main body, at the same time with the high pressure sensor can accurately sense the high-voltage conductor charged state information, realize electrified locking function can control the power state of the contact locking relay and grounding switch. The sensor has the characteristics of simple structure, small volume, without changing the existing PASS body structure, can effectively solve the existing technology has high cost of equipment, the problem of excess function.
