断路器

Wavelet packet decompresses vibration signals, and wavelet packet nodes which are sensitive to the change of state, as eigen-nodes, form a decomposition tree; the signal restructured at all eigen-nodes can be used as the fingerprint in many breaker diagnostic systems. Support vector machine with the "most important" factors at eigen-nodes as input vector classifies the states at "one to others" strategy.

首先利用小波包分解振动数据，提取状态变化敏感节点作为特征节点形成分解树，利用敏感节点重构完好状态振动信号，并以此作为当前大多断路器诊断系统中使用的指纹信号；同时提取特征节点最大系数形成特征向量，作为支持向量机的输入向量，使用&一对其余&策略进行特征分类。

Based on it, the selection of design scheme of fuses and circuit breakers were given out.

在此基础上，给出了设计中有关熔断器和断路器的选型方案。

If the use of fuses and circuit breakers Ways portfolio will play better with the effects of protection.

如果熔断器及断路器的使用方法组合将发挥更好的保护效果。

In general, the greater the distance between your room and the circuit breaker, and the greater the number of appliances in your home, the noisier your power will be.

一般情况下，更多地之间的距离你的房间和断路器，以及更大数量的设备，在您的家，你的力量的噪音会。
