Box-type control device of 10kV loss-reduction streetlamp

Abstract

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.

Description

Technical field: [0001] The invention relates to a street lamp control device, in particular to a 10kV loss reduction street lamp box type control device. Background technique: [0002] At present, the power supply of urban street lamps is usually powered by a 10kV box-type distribution transformer; when lighting is not needed during the day, the power is cut off from the low-voltage side of the transformer; , but the transformer dedicated to street lamps is still in a charged state, that is to say, the street lamp transformer is in a charged and no-load operating state for more than ten hours a day, so that there will be a lot of undue power loss in the power grid. Furthermore, when the street lamp control circuit has a problem and cannot operate normally, or when there is no light during a total solar eclipse and severe bad weather, the street lamp cannot be turned on for illumination when the street lamp is needed at this time.

Problems solved by technology

[0002] At present, the power supply of urban street lamps is usually powered by a 10kV box-type distribution transformer; when lighting is not needed during the day, the power is cut off from the low-voltage side of the transformer; , but the transformer dedicated to street lamps is still in a charged state, that is to say, the street lamp transformer is in a charged and no-load operation state for more than ten hours a day, so there are many undue power losses in the power grid

In addition, when there is a problem with the street lamp control circuit and cannot operate normally, or when a total solar eclipse or severe weather occurs and there is no light, the street lamp cannot be turned on for lighting when the street lamp is needed at this time.
