The invention discloses a box-type control device of a 10kV loss-reduction streetlamp. The box-type control device comprises a
transformer shell, a circuit execution mechanism and a circuit control mechanism, wherein the circuit execution mechanism is arranged in the
transformer shell and is connected with the circuit control mechanism arranged on the outer side of the
transformer shell, the circuit execution mechanism is a circuit formed by sequentially connecting a high-
voltage fuse, a high-
voltage switch, a transformer and low-
voltage branch switches, the circuit control mechanism comprises an intelligent controller and a power supply circuit, a high-voltage switch controller, a low-voltage
branch switch controller and an alarm circuit, the power supply circuit, the high-voltage switch controller, the low-voltage
branch switch controller and the alarm circuit are connected with the intelligent controller, and the high-voltage switch controller and the low-voltage branch switch controller are both connected with the power supply circuit and then are sequentially connected with the high-voltage switch and the low-voltage branch switches. The switching of a streetlamp power supply is achieved by a set numerical value parameter according to
sunrise and
sunset time and natural brightness degree, and the
electric energy loss of a
power grid is reduced; and moreover, the box-type control device has functions of
wireless transmission and alarming, a person is enabled to know the working condition of the streetlamp in real time, and the normal working of the streetlamp is ensured.
