断路器

Circuit breakers are the important equipments in the electric power system, which get out of order due to the inactivation in the aspect of insulation characteristic, mechanical characteristic and electric characteristic,the losses that they cause are a few thousands times more than price of themselves.

断路器是电力系统中的重要设备，在运行过程中可能发生的故障主要是机械故障与绝缘故障，由于它的故障所导致的损失可能为其本身价格的数千倍甚至数万倍，因此对断路器进行状态监测，及时了解断路器的运行状况，成为电力系统十分关注并迫切希望解决的问题之一。

Use the data of circuit breaker on-line working conditon monitoring of ShaoXing Power Bureau, applicate wavelet analysis theory and all kinds of signal dispoing methods, focus on vibration signal and winding electric current wave, at last, provide the fault diagnose result of circuit breaker, and build circuit breakers standard finger library and fault finger library.

The low voltage breaker is composed of electric conducted system,extinguish-arc room, heat tripper and electric magnetism wink-moved mechanism.The functions of move mechanism directly impact the reliability of breaker's move. This topic is imported by using the exchange module of multibody dynamics simulation software automatic dynamic analysis of mechanical system,and then its movement was simulated by applying ADAMS,with the design and the optimization of DW16 Low-voltage breaker's ususal mechanical movement.

摘 要：低压断路器由导电系统、灭弧室、热脱扣器和电磁式瞬动机构组成，其中操动机构的性能直接关系断路器动作的可靠性，本课题利用Pro/E对操动机构进行三维实体造型，然后将利用多体动力学仿真软件ADAMS进行仿真，完成对DW16型低压断路器的常用操动机构的设计和优化。

Adopting double-break structure in low-voltage circuit breaker is going to be a development tendency, for this kind of structure can largely enhance current interrupting performance while it can also minify the volume of circuit breaker.

采用双断点结构的触头系统是低压断路器的发展趋势之一，该结构在大大提高低压断路器开断能力的同时，还可以使断路器体积小型化。

Adopting 2-break structure in low-voltage circuit breaker is going to be a development tendency, for this kind of structure can largely enhance current interrupting performance while it can also minify the size of circuit breaker.

Especially for the research and development of these products such as: mini circuit breaker, moulded-case circuit breaker, leakage circuit breaker, air circuit breaker, surge protective device, isolating switch, double-power automatic transfer switch, motor soft starter, VVVF and distribution box, there is one obvious point for its relatively ahead and professional features.

尤其在小型断路器、塑壳断路器、漏电断路器、万能式断路器、电涌保护器、隔离开关、双电源自动转换开关、电机软起动器、变频调速器、配电箱等领域的研究和开发存在着相对明显的超前性和专业性。

For transformers, circuit breakers to contact the two into line within the circuit breaker for the bridge connection, contact the circuit breakers in the two into line outside the circuit breaker for the bridge connection.

针对变压器，联络断路器在两个进线断路器之内为内桥接线，联络断路器在两个进线断路器之外为外桥接线。

The thesis mainly concerns the following aspects: the relay protection and its trip-close circuit of two circuits transmission-lines are stand alone. The device has the ability of phase-trip that is owns transmission line single phase , 2 or 3phases fault only fault phase tripped.so as to making the power system contact as close as possible. The function of reclosing distribute into relay protection of line and breaker, so it is easy to get no-serious fault information of line protection and realize self-adapted multi pole reclosing. The breaker reclosing depend on the state of owns breaker andthe adjacent breaker. The criterion of serious fault and the sequence reclosing is simple and useful.

本项目具有如下特点：两回线的保护装置及跳、合闸回路完全独立；装置具有分相跳闸功能，即本线单相、两相、三相故障时均只跳故障相，使得故障时系统联系尽可能紧密；重合闸功能合理分配在线路保护和断路器保护中，充分利用了线路保护的信息实现无严重故障判别和分相顺序重合策略的自适应重合功能，由断路器保护根据断路器本身的工作状态和相邻断路器的配合关系实现重合出口；判断严重故障的判据及分相顺序重合闸原理简单合理，具有实用意义，降低了重合于永久故障对系统的冲击。
