| description | The utility model relates to an electric energy meter time code traceability detection system which comprises a clock source machine room, a regional weak current room, a detection table and a detection bin which are sequentially linked and communicated. Standard clock signals output by a clock source machine room are secondarily shunted through regional clock signal shunt control equipment in a regional weak current room, corresponding optical fibers are distributed according to the number of electric energy meter detection tables on the same layer, the standard clock signals are transmitted to the detection tables through the optical fibers, input optical frequency signals are converted into electric frequency signals, and the electric frequency signals are transmitted to the electric energy meter detection tables. After being subjected to frequency phase locking and shunting, the clock signals are provided for each electric energy meter detection bin for use, and meanwhile, the clock signal state of a dete |
