The third switch interval, the fifth switch interval, the thirteenth switch interval and the fifteenth switch interval can be operated according to the requirements of a concrete grid structure, so that the first outdoor switch box assembly and the second outdoor switch box assembly are conveniently connected with one section of bus, two sections of bus, three sections of bus, four sections of bus, five sections of bus and six sections of bus.
2. When the first switch box to be tested or the second switch box to be tested needs to be accessed, the third fast access interval, the sixth fast access interval and the ninth fast access interval of the first fast access box and the first interval to be tested, the second interval to be tested and the third interval to be tested of the first switch box to be tested are connected through flexible cables respectively, or the second fast access box and the second switch box to be tested are connected through flexible cables, so that the labor cost and the time cost caused by wire disconnecting are greatly reduced.
3. The fault access is flexible, faults can be introduced at the front end, the middle end and the rear end of the first switch box to be tested or the second switch box to be tested, and the fault identification and isolation capability of the switch box to be tested is tested in an all-dimensional mode. When no switch box to be tested exists, faults can be introduced into the original net rack of the real-environment test field through each quick access box, and the comparison test with the first switch box to be tested or the second switch box to be tested is convenient.
The above detailed description is given to the components flexibly connected to the switch box to be tested in the power distribution network real-world test platform provided by the embodiment of the present invention, and the principle and the implementation manner of the present invention should be explained by using a specific embodiment herein, and the description of the above embodiment is only used to help understanding the method and the core idea of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
