In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0014] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0015] The utility model will be further described below in conjunction with the accompanying drawings.
[0016] Please refer to Figure 1-Figure 2The utility model discloses a reliable power supply configuration structure for a water intake pump station, comprising: a power supply head structure 1, the power supply head structure 1 comprises a power supply bus 2, a high-voltage transformer 3, a diesel generator 4, and a reserve battery 6, the power supply bus 2 is connected to the high-voltage transformer 3, the diesel generator 4 and the reserve battery 6 through a wire, and the reserve battery 6 is connected to the diesel generator 4 through a wire.
[0017] Among them, a first switch 5 is connected between the diesel generator 4 and the power supply bus 2 through a wire, a second switch 7 is connected between the diesel generator 4 and the reserve battery 6 through a wire, a third switch 9 is connected between the reserve battery 6 and the power supply bus 2 through a wire, a fourth switch 10 is connected to the output end of the high-voltage transformer 3 through a wire, the fourth switch 10 is connected to the high-voltage bus 11 through a wire, the high-voltage bus 11 is 10kv, the high-voltage bus 11 is connected to the fifth switch 12 through a wire, and the fifth switch 12 is connected to the water pump station 13 through a wire.
[0018] Among them, the diesel generator 4 is equipped with a starting igniter 8, the starting igniter 8 is connected to the reserve battery 6 through a wire, the starting igniter 8 and the reserve battery 6 are connected to a sixth switch 15 through a wire, the power supply bus 2 is connected to a controller 14 through a wire, the controller 14 is electrically connected to the first switch 5, the second switch 7, the third switch 9, the fourth switch 10, the fifth switch 12, the sixth switch 15, and the diesel generator 4, and the power supply bus 2 is 380V.
[0019] Specifically, when the utility model is used, when the power supply bus 2 is supplying power normally, the electric energy is transmitted to the high-voltage transformer 3 and the reserve battery 6, and then the transmitted voltage is increased through the high-voltage transformer 3, and the increased voltage is transmitted to the high-voltage bus 11, and then transmitted to the water pump station 13 through the high-voltage bus 11.
