Abstract
The utility model, which belongs to the diesel generating set processing field, relates to an intelligent control apparatus of a starting signal for a diesel generating set. A voltage monitoring relay is installed at a 380-V alternating-current loop of the grid; and a passive normally-closed contact of the voltage relay is connected to a self-starting signal input port of a diesel generating set automatic intelligent controller. The apparatus has the following beneficial effects: the relay enables the contact to make motion according to set delayed time and a starting signal is sent to the generating set; because of the delayed time, the transient fault occurring at the grid or the influence on the monitoring relay by the flashover can be prevented; and after the monitoring relay is added to the generating set, the possibility of maloperation can be completely prevented and the damage on electrical equipment when overvoltage occurs at the grid can also be effectively avoided.
Description
technical fieldthe utility model relates to diesel engine generator block enable signal intelligent controlling device, belongs to diesel generating set manufacture field.
background technologyat present, the effect of Automatic Diesel Generator Set is that enabling signal of the timely supply generator group of net electric system automatic intelligent controller, can start rapidly unit, and do not affect the normal operation of electric equipment when net electricity or electric equipment break down.The self-starting signal of generating set now, by monitoring single-phase 220V or two-phase 380V voltage, as enabling signal, the problem that existing monitoring technology mode exists is, when phase shortage, overvoltage, under voltage, three-phase imbalance appear in electrical network, the relay installing additional cannot accurately be judged real fault, just to generating set, sends signal, cause unit erroneous judgement to start, so just directly cause the damage of frequent starting or the equipment of unit.
summary of the inventionin view of the defect of prior art existence, the purpose of this utility model is to provide a kind of diesel engine generator block enable signal intelligent controlling device, can rapidly, accurately obtain signal, to the automatic intelligent controller of diesel generating set, send enabling signal immediately, engine is worked immediately.
For achieving the above object, the technical solution that the utility model adopts is: diesel engine generator block enable signal intelligent controlling device, voltage monitoring relay is installed in the electric 380V ac circuit of net, and the passive normally-closed contact of voltage relay is connected to the self-starting signal input port of diesel generating set automatic intelligent controller.
Described voltage monitoring relay is for monitoring the power failure phenomenon that three-phase four-line system occurs: wherein, overvoltage protection value is chosen as 110% of rated voltage; Under voltage protection value is chosen as 80% of rated voltage; The protective rate of three-phase imbalance is 20% of rated voltage; Delay time is 0.1-10S.
The effect of the automatic intelligent controller of described diesel generating set is to show defencive function by the start and stop of remote opening signal controlling generating set and perfect fault; adopt 32 ARD single-chip microcomputers; liquid crystal display LCD is 132*64; be with backlight, Chinese, the English and optional interface operation of other multilinguals; the accurate engine that gathers; the various parameters of generator, all parameters can be used PC to adjust by USB interface, can use again PC to pass through RS485 interface and adjust.
Diesel engine generator block enable signal intelligent controlling device, its beneficial effect is: relay can move contact according to the delay time of setting, to generating set, send enabling signal, this delay time can prevent that net electricity from occurring that transient fault or sudden strain of a muscle iron the impact for control relay, generating set increases after this control relay, prevent the possibility of malfunction completely, also effectively taken precautions against, the infringement to electric equipment when overvoltage appears in net electricity.
