Description

Technical Field

[0001] The present invention belongs to the technical field of battery charging equipment, and in particular relates to a high-voltage isolated centralized charging cabinet and a charging method thereof. Background Art

[0002] With the continuous development of science and technology, batteries are used more and more widely in various fields, and the demand for battery charging is also increasing. As an efficient and convenient battery charging device, high-voltage isolation centralized charging cabinets have been widely used in industrial production, logistics warehousing, electric vehicle charging stations, etc. However, the existing high-voltage isolation centralized charging cabinets still have some problems during use.

[0003] Problems with existing technologies: However, in actual use, the existing high-voltage isolated centralized charging cabinets have exposed a series of problems that need to be solved urgently. Battery charging is a complex process. Due to the combined influence of various factors such as the uneven quality of the battery itself, the temperature, humidity and ventilation conditions of the charging environment, serious safety accidents such as battery fires occur from time to time. Once a fire occurs in the charging chamber, the fire can spread rapidly due to the relatively closed internal space of the charging cabinet and the dense electrical equipment. It will not only cause serious damage to the charging cabinet, but also may cause chain failures of peripheral equipment, resulting in huge economic losses and safety hazards. To address this problem, some existing charging cabinets are equipped with fire extinguishing devices in the charging cavity. However, the fire extinguishing process is not completed instantly. From detecting the fire to activating the fire extinguishing equipment and then to successfully extinguishing the fire, the fire still has enough time to cause irreversible burning damage to the precision parts inside the charging cavity. In addition, the fire extinguishing agent sprayed by the fire extinguishing device is often corrosive or sticky, and the cleaning work is extremely cumbersome. It is not only time-consuming and labor-intensive, but may also cause secondary damage to the internal structure of the charging cabinet, affecting the subsequent normal operation of the equipment.

If a first circuit breaker 814 or a charging unit fails, the other charging units can continue to work, thereby improving the reliability and stability of the entire charging system; in addition, the output interface of the charging cabinet and the input interface of the first circuit breaker 814 are standardized, so that the first circuit breaker 814 is installed and fixed and electrically connected.

[0034] Working principle: When installing the first circuit breaker 814, the operation process is simple and efficient. First, the positioning hole 815 at the bottom of the first circuit breaker 814 is accurately aligned with the positioning tube 85 at the bottom of the second mounting plate 81 and plugged. During this process, the conductive contact 811 slidably plugged into the positioning tube 85 will smoothly enter the conductive plug-in slot 816 on the inner wall of the positioning hole 815, thereby achieving stable electrical contact and conduction between the conductive plug-in slot 816 and the conductive contact 811, which lays the foundation for subsequent power transmission; Subsequently, by pushing the second push rod 810, the movable plate 86 is driven to move to one side, and a toothed plate 87 is provided in the third mounting groove provided on the outer wall of the movable plate 86, which moves together with the movable plate 86, and the toothed plate 87 is meshed with the gear 88 located in the third mounting groove.
