Protection systems for minimising the consequences of an electrical internal arc when, in spite of alarm systems, an electric fault takes place in the device it is very important to minimize the damage caused from the internal arc.




Pressure Arc Detectors
When arc fault is generated into a closed or semiclosed environment a pressure wave, moving at sound speed, spreads all around. Pressure sensors are able to signal (with a delay of 9-10 ms) the relevant pressure peak. This signal operates immediately on the breaker that causes failure without waiting the longer operating time of the selective protections. This system don't need any electronicprocessing device and operates in a steady way directly on the tripping coil of the breaker which cause failure by means of a simple wired logics.



Light arc detectors
When a fault arc is generated a flash light, with all IR and visible radiation spectra, is emitted. Of course light reaches each point around the fault instantaneously. Optical electronic receivers are very quick to response and according to their technology can react with fast timing (5-10ms) or ultrafast (1-5 us).
This protection is so quick that is commonly used when there's the necessity to cut the energy of fault in a very short time such as for HV plants.
Light detectors are the preferred ones not only when a very fast reaction is required but also when the compartment is quite open and it is not possible to create a sufficient peak pressure to
operate with pressure arc detectors.
Nevertheless attention must be taken using light arc detectors as they are not able to distinguish between the light coming from a fault arc to the light coming from an operation arc: in these situations the proceeding is to enable tripping coil only if both light and overcurrent are simultaneously present.
A hint to solve previous situation is obtained by using low sensitivity IR light arc detectors where the compartment is not dark and a high sensitivity when the compartment is sealed.
跪谢.

防护系统就是最小内部电弧产生所产生的效果,即便警报系统有故障也会通过内部通电故障预警,可见,最小化由内部电弧引起的故障时非常重要的.
高压电弧探测器
.我不翻译了.我得知道你这个arc是代表什么,很多的简写都是它,也可以是电弧,还可以是audio record channel,audio return channel,所以,我需要知道,这个是关于什么的使用说明书?
貌似楼下用google翻译的?连跪谢都给,翻译得好机械.
