Description
Technical Field

Background
Communication power supplies are fundamental components of communication systems, which, in operation of a substation, mainly supply power to communication loads. The dry contact is an electrical switch having two states, an on and an off. The two dry contacts have no polarity and can be interchanged.
The existing station-side communication power supply dry contact access mode has the following problems: the construction of the cable connection mode is difficult: in some sites, the installation path from the communication machine room to the main control room is far, so that a cable connection mode has certain construction difficulty. This may lead to delays or increased maintenance costs that affect the proper operation of the communication power supply dry contact. Loop voltage mismatch results in grid operation risk: the loop voltage of the remote signaling opening terminal of the public screen at the station end is 110V/DC, and the working voltage of the communication monitoring module is 48V/DC. When the communication monitoring circuit has an insulation problem, the direct current grounding fault of the 110V/DC loop voltage at the terminal of the monitoring module can be caused, so that misoperation of the relay protection device of the transformer substation is caused, and risks are brought to the operation of a power grid.
