摘　　要：某些场合,电泵要在特殊的环境和条件下长期连续的工作,因此配置特殊的起停控制电路和保护电路是完全必要的,所以设计了本文介绍的电泵起停控制与多功能保护电路。电路主要由集成件构成。文中扼要介绍的是电泵欠载延时断电保护,过载分级延时断电保护电路,以及欠载停机后延时自动再起动电路。In some cases, electric pumps are requested to operate under the special circumstance and conditions continuously for a long time. So it is necessary to use special starting or stopping control circuits. Then It is desined that starting or stopping control circuits and multifunctional protecting circuits which is consist of integrated circuits is introduced in this paper. Also the paper briefly presents the protection circuits of delay to stop motors in the conditon of light-load the protection circuits of classified delay to stop motors in the condition of over-load, and the circuits which can automaticallyre-generate the motors after stopping in the condition of light-load.

关 键 词：自动再起动 多功能保护 电机 电泵
