Specific embodiment
Technical solution in order to enable those skilled in the art to better understand the present invention, below in conjunction with of the invention real The attached drawing in example is applied, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described implementation Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common Technical staff's every other embodiment obtained without making creative work, all should belong to protection of the present invention Range.
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawing with embodiment to this Invention is described in further detail.
It is a kind of flow diagram of arc light protecting device criteria check method provided in an embodiment of the present invention referring to Fig. 1, The described method includes:
Step S101: detect whether arc light protecting device to be measured is linked into arc probe interface.
Specifically, the arc probe 7 of arc light protecting device to be measured and check system are connected, generated using arc light light source 9 Arc light, arc light act on arc light protecting device to be measured, and the arc probe 7 of the arc light protecting device to be measured is for detecting arc light Whether protective device is influenced by arc light, and when there is arc fault, arc probe 7 detects arc light, at this point, arc probe 7 with Arc probe interface is connected, if correct connect, arc probe 7 should send data to check system, and check system is sentenced The data variation for breaking and showing arc probe 7 judges that arc probe 7 is by seeing whether the variation of 7 data of arc probe It is no to be connected with arc probe interface, if to be connected with check system.
Step S102: when detecting that the arc light protecting device to be measured is linked into arc probe interface, arc light light is controlled Source 9 sends arc light.
Specifically, when arc light protecting device to be measured is linked into the arc probe interface, it is meant that arc protection to be measured Device is connected with check system, can verify to arc light protecting device to be measured, controls arc light light source 9 at this time and sends arc Light, the arc light act on arc light protecting device to be measured, in order to prevent injury of the equipment by arc light, therefore arc protection to be measured fills Movement can be generated by setting, and protection equipment escapes injury, and the arc light protecting device movement speed to be measured is faster, i.e., reaction speed is got over Fastly, illustrate that the sensitivity of the arc light protecting device to be measured is higher.
