断路器

Molded Case Circuit Breaker Shunt Trip coil and often took part in undervoltage trip coil, Shunt trip coil is the voltage at 70%~ 110% off ...70%~ 110% reliable means of shunt voltage range of movement, 70% minimum, and more than 110% of the shunt itself may be burned ...

塑壳断路器往往有分励脱扣线圈和欠压脱扣线圈，分励脱扣线圈是电压在70%~110%时脱。。。 70%~110%指的分励可靠动作的电压范围，70%为最小值，而超过110%分励本身可能会烧坏。。。。

A line contactor or shunt trip circuit breaker must be installed for safety reasons.

出于安全原因，必须安装线路接触器或并联跳闸线路断路器。

He therefore proposed the use of high-voltage shunt reactors, shunt resistors in the circuit breaker to install, using metal oxide surge arresters and other measures to limit over-voltage and, through the electromagnetic transient simulation verification, can operate in a safe range of over-voltage limit inside, so that the transmission system to maintain safe and stable operation.

因此，提出了使用高压并联电抗器、在断路器上加装并联电阻、采用金属氧化物避雷器等限制操作过电压的措施，并通过电磁暂态仿真计算验证，能将操作过电压限制在安全范围内，使输电系统保持安全、稳定运行。

The mechanism was optimized by taking the position of the key shaft as the design var...

以操作机构的关键轴的位置为设计变量，进行了机构的优化设计，为国内开发新一代低压塑壳断路器提供参考。

I tried my small table saw, the breaker kicked off.

我想我的小桌子上看到的，断路器拉开帷幕。

According to the fault data information and expert"s field knowledge, the system can distinguish the lines and buses which fault occurs in, also judge the line"s fault type and the circuit breakers and relayss action performance and give the maintenance suggestion.

系统能在电网发生故障时，根据故障数据信息和专家领域知识，判别发生故障的线路、母线，线路的故障类型以及断路器、保护的动作性能，并给出维修建议。

After observing the physical course of the single-phase grounding of transmission line, analyzing by the wavelet transformation the transient signals sampled during the fault period from the moment that single-phased grounding occurs to the moment that line breakers work, we can distinguish temporary fault from permanent one through the wave form.

本文提出了一种不同于现有故障类型判别的思路，通过考察线路单相接地故障的物理过程，利用小波变换理论分析处理线路单相瞬时性故障和永久性故障在故障发生后断路器开断前时间段的暂态信号，通过波形识别区分两种故障。

In low voltage threephase AC circuits, the breakers, starters and knifeblade fuses with different number of poles were used for electrical isolation, shortcircuit, overload and groundfault protection.

在低压交流三相线路中，往往需要根据负荷情况或线路的保护要求设置不同极数的断路器、起动器或刀熔开关，以用作线路的电气隔离、短路保护、过负荷保护、接地故障保护、防电击。

Then compare the5 drafts from these aspects such as reliability, flexibility andeconomy, and keep two more reasonable plans than others. The shortcircuit current calculation is carried on.. And main electricequipments including circuit breakers、disconnectors、bus、insulatoretc are choosed according to the result of short circuit currentcalculation. Finally the economy of these two plans are comparedand main electrical connection plan is determined.

然后对这五种方案进行可靠性、灵活性和经济性比较后，保留两种较合理的方案，对这两种方案进行短路电流计算；接着是根据短路电流计算结果进行主要电气设备的选型以及校验，包括断路器、隔离开关、母线、绝缘子等；最后再由经济性比较确定最终的电气主接线方案。

Moreover, they have been applied to two typical electrical main systems reliability assessment, 3/2 breakers scheme and double bus bar scheme. The simulation results have shown the advantages of this method.

基于最小状态割集建立了多状态电气主接线元件的贝叶斯网络模型，对常用的一个半断路器接线方案和双母线接线方案的电气主接线进行了可靠性评估，体现了应用贝叶斯网络进行电气主接线可靠性评估的优势。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
