Embodiment Construction

[0029] Such as figure 1 with figure 2 As shown, a shunt leakage detection system includes a controller and a terminal. The controller is located in the power box of the street lamp, and the terminal is located in the light pole. The controller is connected to the cloud server through the base station and transmits the data to the management platform. Big data analysis of massive street light data can be used as a reference for city management decisions.

[0030] The controller includes a plurality of sub-controllers, each sub-controller is connected to an isolated winding of the transformer.

[0031] The sub-controller is used to send a leakage detection voltage signal, and both the sub-controller and the terminal have a leakage current detection function.

[0032] The sub-controller and the terminal maintain communication through the power line carrier.

[0033] The sub-controller has the function of cutting off the lines under its jurisdiction, and the terminal has the f...

Abstract

The invention discloses a shunt electric leakage detection system, which comprises a controller and a terminal, wherein the controller is located in a street lamp power box, the terminal is located in a lamp post, the controller is connected with a cloud server through a base station, the cloud server is connected with a management platform, and the management platform makes a city management decision by performing big data analysis on massive street lamp data. The system has the advantages that a controller-multi-terminal detection scheme is adopted, shunt electric leakage detection is achieved, electric leakage of a line can be detected, a fault point can be positioned, the system can instruct the terminal to directly cut off power supply of a fault street lamp, and after the fault point is cut off from the line, due to the fact that a fault section is not electrified any more, safety problems do not exist any more, and other lines are still isolated from the ground and are still safe.

Description

technical field [0001] The invention relates to the field of smart street lamps, in particular to a leakage detection method for ensuring the safety of street lamps. Background technique [0002] Smart street lights are an integral part of smart cities and the foundation of smart city construction. Street lamp lighting lines usually not only supply power to street lamps, but also display signs, broadcasting, security, monitoring, festival lights, etc., are often connected to street lamp power supply lines, and the access parties of these devices are usually not owned by the street lamp management department. , and does not necessarily follow the street lamp construction specifications and safety requirements, which will bring problems to system safety. [0003] The current street lamp power supply system is generally grounded by the neutral wire. In such a power supply system, once the output line is grounded, the line will have at least two grounding points. If the groundi...
