In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is according to the structural representation of the element protection tripping matrix inspection device of an embodiment of the utility model.
Embodiment
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is carried out to clear, complete description, obviously, described embodiment is the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
An embodiment of the present utility model has proposed a kind of element protection tripping matrix inspection device; referring to Fig. 1, this device comprises instrument box 1 and the switching value common electrical source 2 that arranges on instrument box, test start end 3, photoelectric isolation module 4, numerical coding display 5, involution button 6, the first tetrad are opened into module 7, the second tetrad and opened into module 8, the 3rd tetrad and open into module 9 and the 4th tetrad and open into module 10.
Described first to fourth tetrad is opened in module and is all provided with four passages, is provided with the switching value input end, light emitting diode and the timer that connect successively on every passage.
As shown in the figure, the first tetrad is opened into module 7 and is respectively arranged with switching value input end 11, light emitting diode 12, timer 13; Switching value input end 14, light emitting diode 15, timer 16; Switching value input end 17, light emitting diode 18, timer 19; Switching value input end 20, light emitting diode 21, timer 22.
The described second to the 4th tetrad is opened in module and is also respectively arranged with four articles of passages, is provided with the switching value input end, light emitting diode and the timer that connect successively on every passage, and its concrete setting is opened into module identical with the first tetrad.
