The device comprises a processing control unit, a time setting unit, a relay driving unit and a power supply interruption time indicating unit, wherein the processing control unit is connected with the time setting unit and is used for setting instantaneous power supply interruption time, the processing control unit is connected with the relay driving unit and used for simulating connection and disconnection of the power grid, and the processing control unit is connected with the power supply interruption time indicating unit and used for displaying instantaneous power supply interruption time of each test. The device can simulate an external power grid instantaneous power supply interruption phenomenon, is convenient to test the external power grid instantaneous power supply interruption time, and has the advantages of being scientific in design, practical, simple to operate and high in testing accuracy.
Description
Technical field
The utility model relates to a kind of proving installation, specifically, has related to a kind of external power grid instant cut-off time test device.
Background technology
In power grid quality test, many times need test the instant cut-off time of external power grid, and then remove to understand grid cut-off and whether equipment is caused damage.Yet; What external power grid adopted is unified high-voltage transmission; Can not directly break off external power grid in the reality and carry out the instant cut-off time test, therefore, design a kind of external power grid instant cut-off time test device that can simulate external power grid instant cut-off phenomenon and just become a necessary thing.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of the utility model is the deficiency to prior art, thereby a kind of design science, practical, simple to operate and external power grid instant cut-off time simulation device that measuring accuracy is high are provided.
To achieve these goals; The technical scheme that the utility model adopted is: a kind of external power grid instant cut-off time test device; It comprises processing and control element (PCE), time setting unit, relay drive unit and power-off time indicating member; Wherein, Said processing and control element (PCE) connects the setting that said time setting unit is used for the instant cut-off time, and said processing and control element (PCE) connects the break-make that said relay drive unit is used to simulate electrical network, and said processing and control element (PCE) connects the instant cut-off time that said power-off time indicating member is used to show each time test.
The relative prior art of the utility model has substantive distinguishing features and progress; Specifically; The utility model can be simulated external power grid instant cut-off phenomenon, and for test provides convenience the external power grid instant cut-off time, it has design science, practical, simple to operate and advantage that measuring accuracy is high.
Description of drawings
Fig. 1 is the structured flowchart of the utility model.
Embodiment
Through embodiment, the technical scheme of the utility model is done further detailed description below.
As shown in Figure 1; A kind of external power grid instant cut-off time test device; It comprises processing and control element (PCE), time setting unit, relay drive unit and power-off time indicating member; Wherein, Said processing and control element (PCE) connects the setting that said time setting unit is used for the instant cut-off time, and said processing and control element (PCE) connects the break-make that said relay drive unit is used to simulate electrical network, and said processing and control element (PCE) connects the instant cut-off time that said power-off time indicating member is used to show each time test.
The utility model in use; At first the unit is set and sets a plurality of instant cut-off time through the said time; Said processing and control element (PCE) is controlled the instant cut-off phenomenon that said relay drive unit drives relay simulation electrical network, when each instant cut-off time that sets arrives according to the instant cut-off time that sets; The said power-off time indicating member indication instant cut-off time arrives; And show that when time instant cut-off time observation consumer is to the reaction of instant cut-off phenomenon each time, consumer minimum instant cut-off time that causes damage is instant cut-off time of required test.
This device adopts one chip microcomputer control, and the precision of power-off time can reach a millisecond rank, can realize the instant cut-off time test to single-phase electricity or three-phase electricity according to the difference that drives relay.
Should be noted that at last: above embodiment only in order to the explanation the utility model technical scheme but not to its restriction; Although with reference to preferred embodiment the utility model has been carried out detailed explanation, the those of ordinary skill in affiliated field is to be understood that: still can make amendment to the embodiment of the utility model perhaps is equal to replacement to the part technical characterictic; And not breaking away from the spirit of the utility model technical scheme, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
