Embodiment 1
[0036] like Figure 1~5 As shown, a ship shore power system includes an AC power distribution module 1, a charging and discharging module 2 installed in a container, an energy storage module 3 and a main control module 5, an AC power distribution module 1, a charging and discharging module 2 and an energy storage module 3 are all connected to the main control module 5; the AC power distribution module 1 is connected to the charging and discharging module 2 through an identifiable plug 6, and is used to convert the voltage of the grid into an input voltage; the charging and discharging module 2 includes an inverter 21, The transformer 22 and the energy storage converter 23, the input end of the inverter 21 is connected to the AC power distribution module 1, the output end of the energy storage converter 23 is connected to the energy storage module 3, and the main control module 5 is used to control the charging and discharging module 2; receive the input voltage, and output the...
Embodiment 2
[0046] Different from Embodiment 1: the detector 42 of this embodiment includes a temperature sensor, a smoke detector, a gas flow detector and an oxygen concentration detector, and a temperature sensor, a smoke detector, a gas flow detector and an oxygen concentration detector connected to the control unit. The temperature sensor is used to monitor the environmental changes of the shore power module in real time and convert them into corresponding temperature values. The smoke detector is used to monitor the environmental changes of the shore power modules in real time and convert them into corresponding smoke concentrations. Oxygen is needed in the initial stage of a fire. Combustion, oxygen starts to flow, and the gas flow meter on the top can quickly detect the flow of gas, which is helpful for early detection of fire, fire extinguishing, and reduction of large losses. At the same time, the reduction of oxygen will be detected by the oxygen concentration meter in time. Dis...
Embodiment 3
[0049] The difference from Embodiment 1 is that the identifiable plug 6 of this embodiment includes a male plug and a female plug, an identification chip is provided on the male plug, and an identifier matching the identification chip is provided on the female plug, so that the identification chip of each line and the The identifiers are paired one by one, but the male or female plugs with different identification chips cannot be paired, which helps to reduce the probability of mis-insertion. In addition, the female plug is equipped with a magnetic ring and a movable permanent magnet corresponding to the magnetic ring. When the identification chip and the identifier cooperate, the identification is successful, and the magnetic ring generates magnetism. The magnetism of the magnetic ring is the same as that of the permanent magnet. The space for insertion; the outer side of the male plug and the outer side of the female plug are both covered with a buffer layer to limit shaking;...
