过载电流

According to the selected electric actuator determine the electrical parameters Because of different electric actuator manufacturers have different electrical parameters, design selection Butterfly Valves generally takes time to determine their electrical parameters, mainly electric power, rated current, secondary voltage control loop, are often negligent in this regard, the results of control system and the electric actuator parameter does not match the space-time caused by the work of opening trip, fuses, fuse, thermal overload relay protection is like a take-off and other failures.

根据所选电动执行器确定电气参数因不同电动执行器厂家的电气参数有所差别，所以设计选型时一般都需确定其电气参数，主要有电机功率、额定电流、二次控制回路电压等，往往在这方面的疏忽，结果控制系统与电动执行器参数不匹配造成工作时空开跳闸、保险丝熔断、热过载继电器保护起跳等故障现像。

Safe protector-Chiller includes current overload relay , high/low pressure , oil pressure , frozen prevention , time delay , and phase voltage protector , etc .

安全装置－冷水机装有电流过载保护，高低压擎，油压擎，防冰擎，电子时间延迟，电压保护等安全装置，当发生故障时，随即发出警号及显示故障原因。

Equipped with phrase protection relay, power short-cut protection, current overload protection, hi-low voltage switch, freeze protection, water fiow control, electronic time holdup device,etc.

装有相序保护、电源短路保护、电流过载保护、高低压控制、结冰保护、水流制、电子时间延迟安全装置。

According to this invention, the provided AC two-wire switch may greatly reduce the additional on-state voltage-drop and the additional off-state current, and furnish the best short-circuit protection and quick-acting overload protection.

根据本发明，被提供的交流的双线的开关可以极大地降低另外的接通的电压降和另外的关态电流，并且提供最好的短路保护装置和速动的过载保护。

4 The overcurrent-protective device specified in 27.1 shall not be of the automatically-reset type but shall be trip-free when of the manually-reset type.

27.1(6)中所指的电流过载保护装置，不应是自动型的而应是自由移动的手动型装置。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
