技术领域Technical Field
本申请涉及储电设施技术领域，特别涉及一种增补电柜和储能电站。The present application relates to the technical field of power storage facilities, and in particular to an additional power cabinet and an energy storage power station.
背景技术Background technique
随着工商业储能市场的稳步发展，地面储能安装量持续提升。由于自身的衰减特性，储能电池的能量将会随着使用时间的增长而逐渐降低。为保证并网点的额定可放电池电量，同时减少储能电站的初始投资成本，业主通常选择在储能电站全生命周期内用小颗粒度的储能产品增补若干次的方式。With the steady development of the industrial and commercial energy storage market, the amount of ground energy storage installed continues to increase. Due to its own attenuation characteristics, the energy of the energy storage battery will gradually decrease as the use time increases. In order to ensure the rated dischargeable battery power of the grid connection point and reduce the initial investment cost of the energy storage power station, the owner usually chooses to use small-granularity energy storage products to supplement several times during the life cycle of the energy storage power station.
现有的工商业储能柜通常不具备直接与储能电站进行合并连接的功能，不能较为方便地实现对大型储能电站进行补充。且现有的工商业风冷储能***散热效率低、耗能大，温控范围限制大，对电芯寿命影响大。Existing industrial and commercial energy storage cabinets usually do not have the function of directly connecting to energy storage power stations, and cannot easily supplement large energy storage power stations. In addition, the existing industrial and commercial air-cooled energy storage system has low heat dissipation efficiency, high energy consumption, and a large temperature control range, which has a great impact on the life of the battery cell.

本实施例中，门板13的一端与柜体10铰接，当门板13闭合时，门板13的表面抵压密封圈119，从而实现对相应仓室的密封。In this embodiment, one end of the door panel 13 is hinged to the cabinet body 10. When the door panel 13 is closed, the surface of the door panel 13 presses against the sealing ring 119, thereby achieving sealing of the corresponding chamber.
增补仓111与储能仓113、液冷仓115与控制仓117，皆采用共门板13的设计方案，即通过一个门板13同时实现增补仓111与储能仓113，或液冷仓115与控制仓117的封堵。参照图6，由于每个仓室的开口处均设有一个密封圈119，因此上下的仓室之间通过两层密封圈119充分隔离，使上下的仓室不相干涉，不相连通。如此，通过一块门板13即可实现两种防护等级的需求，比如，位于柜体10上方的增补仓111和液冷仓115需满足IP20的防护需求，而下方的储能仓113和控制仓117满足IP54的防护需求。The supplementary compartment 111 and the energy storage compartment 113, the liquid cooling compartment 115 and the control compartment 117 all adopt the design scheme of a common door panel 13, that is, the supplementary compartment 111 and the energy storage compartment 113, or the liquid cooling compartment 115 and the control compartment 117 are blocked at the same time by one door panel 13. Referring to Figure 6, since a sealing ring 119 is provided at the opening of each compartment, the upper and lower compartments are fully isolated by two layers of sealing rings 119, so that the upper and lower compartments do not interfere with each other and are not connected. In this way, the requirements of two protection levels can be met by one door panel 13. For example, the supplementary compartment 111 and the liquid cooling compartment 115 located above the cabinet 10 need to meet the protection requirements of IP20, while the energy storage compartment 113 and the control compartment 117 below meet the protection requirements of IP54.
