Outdoor lighting power distribution cabinet protection controller

Abstract

The invention discloses an outdoor lighting power distribution cabinet protection controller which belongs to the field of a lighting system. According to the controller, a power supply input end is connected with an MCU control unit on a power supply circuit; a power supply output end of the power supply circuit is connected with an immersion detection circuit and a GPRS remote communication circuit. The signal input end of the MCU control unit is respectively connected with the immersion detection circuit and a voltage sampling circuit. The MCU control unit carries out remote communication with a control center through the GPRS remote communication circuit. The signal output end of the MCU control unit is connected with a relay module which controls on and off of a street light and the power supply of a power distribution cabinet. The signal input end of the MCU control unit is connected with a leakage detection circuit. The leakage detection circuit is provided with a transformer which is used for detecting the current of an input cable of the power distribution cabinet. The power supply circuit is connected with the commercial power. According to the invention, the problem of low power distribution cabinet security is solved; leakage of the power distribution cabinet is avoided; the field security of the power distribution cabinet is improved; and the controller can be used for street light management.

Description

technical field [0001] The invention relates to a lighting system, in particular to a lighting distribution cabinet. Background technique [0002] With the advancement of my country's urbanization process, the corresponding basic supporting facilities have also been developed, and road lighting and landscape lighting embellish the bustling night scene of the city. However, these lighting systems are not safe, and there are often cases of personal injury and death caused by street lamp leakage after heavy rain. These accidents are usually caused by electric leakage caused by flooding of power distribution cabinets after heavy rains or other reasons. The deep-seated reasons can be attributed to construction problems, line aging problems, natural disasters and other problems. These problems are usually not easy to find or predict, and once they happen, they may have caused accidents. Fortunately, some urban street lighting authorities have paid attention and taken some measur...
