Abstract
The utility model discloses a kind of multi-functional load prior-warning device, comprise control panel, this control panel is provided with power interface, CT interface and PT interface, described control panel is also provided with alarm interface, phase shortage interface and mistake stream interface, described alarm interface, phase shortage interface and mistake stream interface are placed on described control panel side successively side by side.By adding alarm, phase shortage on the control panel and crossing stream interface, alarm is carried out to the phase shortage occurred in three-phase current and overload phenomenon, contributes to the maintenance at plant area scene, reduce the generation of electric power accident.
Description
Technical field
The utility model relates to electric instrument technical field, is specifically related to a kind of multi-functional load prior-warning device be applied in instrument.
Background technology
When electrical control cubicles connects three-phase current, electric instrument can only play the effect connecting power supply, the electric current that three-phase current is transmitted can only be passive reception, cannot early warning be carried out in phase shortage and overload to three-phase current, easily cause device damage, cause in production and occur unexpected power cut problem, affect produced on-site.
Utility model content
For solving the problems of the technologies described above, we have proposed a kind of multi-functional load prior-warning device, cannot early warning three-phase current whether phase shortage and overladen problem in order to solve in electric instrument.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of multi-functional load prior-warning device, comprise control panel, this control panel is provided with power interface, CT interface and PT interface, described control panel is also provided with alarm interface, phase shortage interface and mistake stream interface, described alarm interface, phase shortage interface and mistake stream interface are placed on described control panel side successively side by side.
Preferably, described CT interface and power lead adopt three-phase CT to access.
Preferably, described PT interface and power lead adopt three-phase PT to access.
Pass through technique scheme, the beneficial effect that the utility model obtains is: by adding alarm, phase shortage on the control panel and crossing stream interface, alarm is carried out to the phase shortage occurred in three-phase current and overload phenomenon, contributes to the maintenance at plant area scene, reduce the generation of electric power accident.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the circuit theory schematic diagram of a kind of multi-functional load prior-warning device disclosed in the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and embodiment, the utility model is described in further detail.
Embodiment.
As shown in Figure 1, a kind of multi-functional load prior-warning device, comprises control panel, this control panel is provided with power interface L (01) and N (02), can connects the combined-voltage of 25V-265V; Ua (11), Ub (12), Uc (13) and Un (14) are the CT interface on control panel, adopt the method for three-phase CT access to be connected with three-phase current; Ia+ (15), Ia-(16), Ib+ (17), Ib-(18), Ic+ (19) and Ic-(20) are the PT interface on control panel, adopt the method for three-phase PT access to be connected with three-phase current; The communication interface that 485A (09) and 485B (10) is this control panel, is connected for carrying out signal with the external world; Described control panel is also provided with alarm interface, phase shortage interface and mistake stream interface, described alarm interface, phase shortage interface and mistake stream interface are placed on described control panel side successively side by side.Wherein alarm interface connects hummer, and phase shortage interface is connected display lamp with mistake stream interface.When three-phase current occurs phase shortage or crosses stream load, the display lamp that corresponding interface can connect can glimmer and hummer pipes.Technical solutions of the utility model, by adding alarm, phase shortage on the control panel and crossing stream interface, are carried out alarm to the phase shortage occurred in three-phase current and overload phenomenon, are contributed to the maintenance at plant area scene, reduce the generation of electric power accident.
Above-described is only the preferred implementation of a kind of multi-functional load prior-warning device of the utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
