Charging station electricity safety monitoring device and early warning method

Abstract

The invention relates to a charging station electricity safety monitoring device and an early warning method. The device comprises three parts of an electric fire early warning device, a fire controldevice and a fire early warning management platform, wherein the electric fire early warning device is used for monitoring current, voltage, zero line current, residual current, reactive power, activepower and the like of an electric circuit of the charging station, the data are uploaded to the fire early warning management platform, the fire early warning management platform calculates and obtains warning signals through a warning algorithm according to historical data and real-time data, the warning signals are transmitted to the electric fire early warning device, the early warning devicegives warning signals, control signals are outputted, and the fire control device is driven to make corresponding actions.

Description

technical field [0001] The invention relates to a power consumption safety monitoring device and an early warning method for a charging station, which is suitable for monitoring whether the power consumption of the charging station is in a safe state, and for early warning of a dangerous power consumption state. It ensures the safe use of electricity at the charging station and reduces unnecessary personal and property losses. Background technique [0002] Economic development promotes the rapid development of urbanization, and the population is increasingly concentrated in cities. Cars, as people's main means of transportation, have become the main source of carbon emissions, and carbon dioxide and other gas emissions lead to climate warming. In order to reduce carbon emissions and get rid of oil dependence, the development trend of new energy vehicles is irreversible, and there is huge room for future growth. Therefore, people's demand for charging stations is becoming ...

Problems solved by technology

However, the current safety regulations do not allow the installation of an overcurrent protection device on the neutral line, resulting in an uncontrollable fire on the neutral line

[0004] Existing electrical fire safety products on the market mainly adopt the post-alarm method of detecting abnormal residual current and temperature after a fire occurs, focusing on leakage and fire monitoring, with little monitoring data and no further data analysis, and the multi-node detection effect is not good , slow

Some other important factors, such as neutral current, harmonics, reactive power, active power, and power factor, have not been considered comprehensively, and the functions of predicting, early warning, and prevention of danger cannot be achieved

Moreover, the traditional fire alarm system relies on on-site equipment, is not highly intelligent, and has poor real-time performance, making it difficult to prevent and timely rescue
