The wireless communication module comprises a power interface, a network cable interface, an SIM card slot, a power button and an external antenna interface; the feeder automation network test system can provide a wireless network for the feeder automation tester and support feeder automation networking test.
Referring to fig. 1, firstly, aiming at the problem that the tester and the power distribution terminal are difficult to connect and cannot be adapted to each other, the portable feeder automation test switching device externally presents two interfaces, one is in a banana plug form and used for connecting the switching device to the tester side, and the other is in an aerial plug form and used for connecting the switching device to the power distribution terminal side. The two interfaces realize the one-to-one correspondence of the interface pins in the portable switching device through the conversion board, and effectively solve the problem that the input and output modes of the tester are pin insertion modes, and the power distribution terminal is aerial insertion mode, so that the connection cannot be realized.
In addition, as can be seen from fig. 2, the number of the main panel open-in and open-out indication areas is 14, which is due to the consideration that the power distribution terminal open-in and open-out aviation plug has two types, namely 10 cores and 14 cores, and is compatible with two different aviation plug forms, and when the 10-core aviation plug is used, redundant four open-in and open-out jacks are automatically suspended, so that normal test cannot be influenced.

In the testing process, the red indicator light of the main panel is turned on to indicate that the channel is in the working state at present, and a user can be prompted according to the condition that the input and output circuit of the tester or the power distribution terminal is defective.
Finally, the portable switching device needs a built-in wireless communication module. In the feeder automation test, a plurality of testers are required to be matched to meet the test requirement, so that the data of the local tester is forwarded to a remote control center through a 4G network by a wireless communication module, the purpose of unified monitoring is achieved, the cooperative work of the plurality of testers is realized, and the complexity of the coordinated and matched work of field operators is reduced. The wireless communication module can be connected with the tester in a wifi form, and for the tester without a built-in wifi module, the tester and the portable switching device also need to be supported to be directly connected in a network cable mode. Therefore, the portable adapter device also needs a network cable interface and a power supply interface. In addition, it can be seen that the SIM card slot of the communication module needs to be arranged at the main panel, which is convenient for the user to replace the SIM card.
