Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of bypass relay wiring box as shown in Figure 1, it is sent by Surveillance center 7 by receiving, the instruction transmitted through rf control unit 6 and realize the by-path turn-on of terminal box.Described terminal box has junction box body 1, and described junction box body 1 comprises terminal box body 1-1 and the monitoring box body 1-2 with terminal box body 1-1 clamping.In junction box body 1, spacing is provided with four junction blocks 2, described junction block 2 connects cell piece group 4 by busbar 3, surface-mounted integrated circuit and signal output port is provided with in monitoring box body 1-2, surface-mounted integrated circuit is fixed on the pedestal of monitoring box body 1-2, surface-mounted integrated circuit is provided with controller, energy storage, super low-power consumption processor and wireless launcher four functional modules, controller receives the signal of telecommunication gathered in terminal box body 1-1, temperature signal and flux signal, after voltage stabilizing and anti-recoil process, be transferred to super low-power consumption processor carry out integrated calculating, result of calculation is transferred to Surveillance center 7 by signal output port, the electric energy that controller receives is stored by energy storage.
The relay 5 of by-path turn-on one Battery pack sheet group 4 is provided with, relay 5 received RF controller 6 signal transmission and realize the opening and closing of its switch between adjacent two junction blocks 2.In present embodiment, the respective corresponding relay 5 in parallel of three Battery pack sheet groups 4, when the cell piece group 4 of photovoltaic system is in normal operating conditions, electric current directly passes through between cell piece group 4, and the switch of relay 5 is in off-state; If Surveillance center 7 receives the signal of telecommunication, temperature signal and flux signal that controller gathers in terminal box body 1-1, show that certain Battery pack sheet group 4 breaks down by analyzing, namely Surveillance center 7 sends action command, rf control unit 6 is transferred to by communication modes, rf control unit 6 transfers signals to relay 5, closed by relay 5 control switch, the electric current in cell piece group 4 intact so is just skipped the cell piece group 4 that breaks down and is flow through from terminal box.
The utility model is on conventional electrical connectors basis, install monitoring box body 1-2 additional, and sets up the modules such as the signal of telecommunication, temperature signal and flux signal in monitoring box body 1-2, defines so-called Intelligent Measurement terminal box.Because the distribution of photovoltaic module is more wide, first to set up the single-stage of photovoltaic module and relay station or multistage radio-frequency communication, the wire communication of relay station and Surveillance center 7 can be adopted afterwards, realize effective transfer of data.And Surveillance center 7 receives each bypass voltage that Intelligent Measurement terminal box transmits and the electric current passed through, carry out analyzing and diagnosing according to voltage and current (power) parameter, implement to realize bypass to the control of relay 5 in each bypass, namely realize the open/close work of relay 5.Employ the terminal box of bypass relay, its maximum advantage is that relay 5 can not produce very large heat when by-path turn-on, lossless, and can intelligently set by-path turn-on voltage, realizes maximum power output.
Above-mentioned execution mode is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection range of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection range of the present utility model.
