技术领域technical field
本发明涉及高压断路器领域，具体而言，涉及一种高压断路器检测方法和装置。The invention relates to the field of high-voltage circuit breakers, in particular to a detection method and device for high-voltage circuit breakers.
背景技术Background technique
机械故障是高压断路器的主要故障类型。尽早发现断路器电气控制回路和操动机构中的缺陷和故障，不仅可以避免发生断路器操作故障以及避免发生事故，同时，也可以为断路器的故障维修提供必要的依据。Mechanical failure is the main failure type of high voltage circuit breakers. Early detection of defects and faults in the circuit breaker electrical control circuit and operating mechanism can not only avoid circuit breaker operation failures and avoid accidents, but also provide the necessary basis for circuit breaker fault maintenance.
高压断路器在开始工作时，分合闸电磁铁线圈首先上电，之后通过一系列的机械联动实现储能机构中能量的释放，进而通过力的传递和力的方向控制以带动动触头运动。电磁铁线圈电流可以反映电磁铁铁心运动与脱扣部件的碰撞情况。整个过程中，零部件之间的机械撞击、摩擦，以及机械力、电动力等的作用均可以激发断路器的机械振动。断路器的机械振动信号通过设备零部件之间的连接向外传播，该信号可以在传播路径和开关的机座、外壳上测得。When the high-voltage circuit breaker starts to work, the opening and closing electromagnet coils are first powered on, and then the energy in the energy storage mechanism is released through a series of mechanical linkages, and then the moving contact is driven by force transmission and force direction control . The electromagnet coil current can reflect the collision between the movement of the electromagnet core and the tripping part. During the whole process, the mechanical impact and friction between components, as well as the action of mechanical force and electric force can excite the mechanical vibration of the circuit breaker. The mechanical vibration signal of the circuit breaker propagates outward through the connection between the equipment components, and the signal can be measured on the propagation path and the switch frame and casing.
在现有技术中，高压断路器生产厂家大多采用开关特性测试仪，通过对断路器线圈电流、行程和断口信号的测试和分析，得到断路器的分合闸时间、分合闸速度、行程和超程特性、弹跳等机械特性参数。在电力系统中检修人员大多采用便携式的断路器机械特性测试仪对断路器线圈电流和端口信号进行测试和分析，得到断路器的分合闸时间，以便对断路器的操作特性有一个总体的判断。这些测试方法，可以得到断路器总体的操作特性，但是测量装置本身对于故障缺陷的发现是无能为力的。In the existing technology, most high-voltage circuit breaker manufacturers use switch characteristic testers to obtain the opening and closing time, opening and closing speed, stroke and Overtravel characteristics, bounce and other mechanical characteristic parameters. Most maintenance personnel in the power system use portable circuit breaker mechanical characteristic testers to test and analyze the circuit breaker coil current and port signals, and obtain the opening and closing time of the circuit breaker, so as to have an overall judgment on the operating characteristics of the circuit breaker . These test methods can obtain the overall operating characteristics of the circuit breaker, but the measurement device itself is powerless for the discovery of fault defects.
现有的其他类型的高压断路器机械状态检测系统，大多只具备信号的测试和分析功能，其中测量的信号可以包括：线圈电流、行程、机械振动等，但很少具备机械状态诊断功能，一般只能给出断路器操作特性的基本参数，因此难以对及时对高压断路器当前的机械状态的故障缺陷类型进行诊断。Most of the existing other types of mechanical state detection systems for high-voltage circuit breakers only have the function of testing and analyzing signals. The measured signals can include: coil current, stroke, mechanical vibration, etc., but rarely have the function of diagnosing the mechanical state. Only the basic parameters of the circuit breaker's operating characteristics can be given, so it is difficult to diagnose the fault defect type in time for the current mechanical state of the high voltage circuit breaker.
针对现有技术中难以及时对高压断路器的机械故障进行诊断的问题，目前尚未提出有效的解决方案。Aiming at the problem in the prior art that it is difficult to diagnose the mechanical failure of the high voltage circuit breaker in time, no effective solution has been proposed yet.
