Technical Field

[0001] The invention relates to an online detection device and a detection method for safety management of a new energy power station, belonging to the technical field of management of new energy power stations. Background Art

[0002] At present, new energy power station systems such as photovoltaic power stations, wind power stations and energy storage power station systems built based on waste lithium battery packs often need to use a large number of battery packs to store electric energy during operation. These energy storage batteries are often distributed over a wide range and have a high distribution density during operation. As a result, on the one hand, it is necessary for staff to conduct equipment inspections and maintenance management in a larger area. In addition, due to the large distribution density of the equipment, a large number of parts cannot be directly detected, which increases the difficulty of detection and management. On the other hand, it is very easy to cause failures or even spontaneous combustion of energy storage batteries due to external high temperature environment and waste heat generated during power system operation. In addition, failures of power components and short circuits in the circuit system during operation can also cause fires in energy storage batteries. To address this problem, the current main method is to use traditional equipment structures that are often used for equipment equipped with energy storage batteries, such as the patent application number "202 410857306.2", "a stable new energy battery energy storage box", "a supporting energy storage system for new energy power stations" with patent application number "202322647448.X", and "a new energy high-voltage lithium battery energy storage system" with patent application number "201910697598.7", etc. However, these devices can only meet the needs of physical packaging and isolation of energy storage batteries, but have great defects in the monitoring of the operating status of energy storage batteries and spontaneous combustion emergency fire disposal. At the same time, they cannot meet the needs of remote online synchronous monitoring and management operations, which seriously affects the work efficiency and accuracy of supervision operations. It is often necessary to set up additional auxiliary monitoring systems, fire rescue systems and other equipment or systems for auxiliary operation, which makes the system structure of current new energy power station energy storage equipment complicated on the one hand; on the other hand, it causes the adjustment of the operating environment of energy storage batteries and the efficiency of fire rescue to be relatively low.

While the monitoring cameras comprehensively monitor the working status of the energy storage battery pack in the protection chamber, the temperature and humidity sensors detect the working temperature and humidity parameters of the energy storage battery pack. On the other hand, the air sensors and smoke sensors detect the smoke and odor generated by spontaneous combustion during the operation of the energy storage battery pack to meet the needs of safety monitoring. At the same time: When the operation of the energy storage battery pack and its own working state are detected to be abnormal, firstly, the electrical connection between the operation panel and the energy storage battery pack in the protection cavity is disconnected through the explosion-proof terminal; When the temperature and humidity of the working environment of the energy storage battery pack are detected to be abnormal, the heat dissipation mechanism is driven to operate and the temperature in the protective cavity is lowered; When a fire hazard or spontaneous combustion of the energy storage battery pack is detected, on the one hand, the fire-fighting agent buffer tank and the sprinkler pump are driven to operate and the energy storage battery pack in the protection cavity is sprayed with fire-fighting agent to extinguish the fire; on the other hand, the heat dissipation mechanism is driven to operate and the heat dissipation mechanism is used to assist in cooling and suppressing the combustion. At the same time, the air in the protection cavity is forcibly discharged through the return air port to reduce the oxygen content in the protection cavity, thereby suppressing the combustion and preventing the fire from spreading, and assisting the fire-fighting operation by spraying the fire-fighting agent.
