Description

Technical Field

[0001] The present invention relates to the field of power distribution devices, and in particular to a vehicle-mounted intelligent prefabricated power supply cabin monitoring system and a monitoring method. Background Art

[0002] The economic and social development is increasingly dependent on electricity, which is mainly reflected in: on the one hand, the user's electricity demand is growing rapidly.

[0003] On the other hand, users have increasingly higher requirements for power quality.

[0004] Power outages will inevitably have serious impacts on social production, national security and people's lives.

[0005] At present, most domestic mobile energy storage vehicles or emergency power supply vehicles are large megawatt-class container-type or small power bank-type. The container-type structure is not flexible enough, has poor maneuverability, and a simple control method, which makes it difficult to meet the needs of small and medium-sized urban power supply emergency scenarios; the charging and discharging functions are single, which makes it difficult to meet the multiple applications of power supply, rescue, emergency repair, and emergency power supply; there is no unified design standard for existing mobile energy storage vehicles, and there is a large gradient gap in functional performance, battery selection, and capacity sequence. Domestic mobile energy storage vehicles mostly use diesel generators as emergency power sources. Diesel generators have a long start-up time, large fluctuations in power supply voltage and frequency, and low efficiency. Diesel generators will inevitably cause environmental and noise pollution, and the size and weight of diesel generators limit the rapid maneuverability of mobile energy storage vehicles.

[0006] In recent years, various oilfield enterprises have comprehensively promoted green and low-carbon production methods while ensuring national energy security and continuously increasing their exploration and development efforts. They have vigorously implemented the electrification of terminal energy consumption, and a large number of new mining equipment such as grid-powered drilling rigs, electric-driven pressure drives, and grid-powered well repairing have been invested in the power grid.

[0007] The original temporary power supply power-on workflow requires enterprises to assemble and debug various electrical equipment (pole-mounted circuit breakers, disconnectors, high-voltage metering boxes, lightning arresters, cables, FTUs, poles, protective pipes, insulating shields, etc.) on site on the distribution lines.

[0008] The installation process is labor-intensive, time-consuming, and involves various safety risks. The degree of standardization is low at the later stage of load power consumption, and the power consumption process is unsupervised, resulting in high management and inspection costs. After the drilling work is completed, the workload of dismantling the power distribution facilities is heavy, resulting in a waste of manpower, material resources, and time. Therefore, prefabricated power supply warehouses installed on transport vehicles came into being.

[0009] The Chinese patent with the publication number CN218514125U discloses a vehicle-mounted light mobile power supply cabin, and also discloses the following technical features: A vehicle-mounted light mobile power supply cabin includes a cabin and a energy storage battery system adapted inside it. The cabin also includes a cabin base for detachably mounting on the vehicle and a cabin outer cover mounted on the cabin base. The cabin outer cover includes a cabin outer cover upper shell, a cabin outer cover left side shell, a cabin outer cover right side shell and a cabin outer cover rear side shell that are detachably and waterproofly connected to each other. The cabin base is L-shaped. The bottom side of the L-shape is detachably mounted on the vehicle, and the longitudinal side is opposite to the rear side shell of the outer cover. The human-machine interaction panel is provided on the outer surface of the longitudinal side.

[0010] The internal structure of the cabin provided by the above-mentioned utility model patent adopts a modular and drawer-type design to reduce the volume and weight of the cabin. The cabin adopts a design of seamlessly adding a cabin outer cover on the cabin base. After the cabin outer cover is opened, all sides of the cabin can be used to repair modular and drawer-type units such as the energy storage battery pack and the energy storage inverter module, which is convenient for installation and maintenance.

[0011] However, the above patent cannot achieve real-time monitoring of the power supply and distribution of the power supply cabin, and it is difficult to grasp the working status of the power supply cabin in real time.

[0012] The Chinese invention patent with the publication number CN110389301A discloses a vehicle-mounted power supply monitoring device, and also discloses the following technical features: A vehicle-mounted power supply monitoring device includes: an MCU module, a Bluetooth and a power supply voltage monitoring circuit. Among them, the first output end of the vehicle-mounted power supply is electrically connected to the input end of the power supply voltage monitoring circuit, and the output end of the power supply voltage monitoring circuit is electrically connected to the MCU module; the second output end of the vehicle-mounted power supply is respectively electrically connected to the MCU module and the Bluetooth to supply power to them. When the vehicle-mounted power supply monitoring device is working, it monitors the output voltage of the vehicle-mounted power supply through the power supply voltage monitoring circuit. When the MCU module detects that the output voltage of the vehicle-mounted power supply is abnormal, the MCU module transmits the abnormal information through the Bluetooth.

[0013] By connecting the vehicle-mounted power supply monitoring device to the vehicle-mounted power supply, the above patent can monitor the status of the vehicle-mounted power supply in real time without adding too much load. The vehicle-mounted power supply monitoring device of the present invention has a simple structure and works safely and reliably.

[0014] However, the above-mentioned patent cannot monitor parameters such as the temperature of the power supply compartment and toxic and harmful gases. Some power supply compartments are equipped with lithium batteries. When a lithium-ion battery undergoes thermal runaway, a series of chemical reactions will occur inside, releasing a large amount of heat and gas. For example, the decomposition reaction of the solid electrolyte interface (SEI) film (90~120°C), the reaction between the negative electrode and the electrolyte (100~350°C), the decomposition reaction of the electrolyte (110~300°C), the shrinkage and melting reaction of the separator (>130°C), the reaction between the positive electrode and the electrolyte (200~300°C), and the decomposition reaction of the binder (200~300°C), etc. The gas released by the thermal runaway of the battery not only has toxicity but also has the risk of combustion and explosion.

[0015] The Chinese patent with the publication number CN215284419U discloses an intelligent battery swapping system, disclosing the following technical features: an intelligent battery swapping system, including a battery swapping cabinet and a lithium battery; the battery swapping cabinet includes a battery swapping cabinet housing, a main control board of the battery swapping cabinet, a main control board of the charging and battery swapping program, a charging power supply, a thermoelectric refrigeration component, and a temperature monitoring device; wherein, the battery swapping cabinet housing includes a power supply compartment, a charging compartment, and a control compartment; the main control board of the battery swapping cabinet is respectively connected to the main control board of the charging and battery swapping program, the charging power supply, the thermoelectric refrigeration component, and the temperature monitoring device.

[0016] The above device can be compatible with lithium batteries of various specifications, can automatically regulate the temperature of the charging compartment, and can also heat up or cool down the lithium battery by monitoring the temperature of the battery cells in the lithium battery, and can spray water to extinguish the fire through a water spraying device when a fire breaks out on the surface of the charging compartment or the lithium battery, thereby avoiding a violent explosion of the lithium battery during the charging process and solving the technical problems existing in the charging and battery swapping of lithium batteries in the prior art.

[0017] However, the above-mentioned disclosed solution has the following deficiencies: it can only perform temperature monitoring to prevent dangers such as explosion caused by too high temperature, the monitoring function is single, and it cannot comprehensively monitor the power supply compartment. Summary of the Invention

At the same time, the circuit breaker is also used for power-off during maintenance.

[0022] Preferably, the parameter recording module is used to record the extreme values and times of power, current, phase voltage and phase current in a day, real-time record three-phase voltage, three-phase current, active electric energy and power data, real-time record the power consumption values of each circuit, and record telemetry events, over-line events and alarm information.
