Description

Technical Field

[0001] The utility model belongs to the technical field of protective nets, and in particular relates to a protective net for an energy storage battery box. Background Art

[0002] Electrochemical energy storage equipment is mainly composed of several battery boxes connected in series or in parallel, with connecting cables and communication control harnesses between the battery boxes. In order to facilitate wiring and debugging, cables and harnesses are laid on the outer surface of the battery box with open wires.

[0003] The voltage of the wires in the wiring harness is generally a safe voltage below 36V, while the voltage of the cable is generally between DC 1000V and 1500V. Reading through the relevant provisions of GB / T13870.1-2022 "The Effects of Electric Current on Humans and Livestock", it can be seen that no matter what the working conditions are, the perception threshold, reaction threshold and other indicators of direct current are much smaller than those of alternating current. In other words, under the same circumstances, the same voltage level of direct current and alternating current will cause more serious consequences for human body after electric shock. At present, the DC cables between battery boxes are mainly protected from direct contact electric shock by the insulation layer. However, as the years of operation increase, the insulation layer will age and break, and the cable still has exposed conductors at the terminal, both of which can lead to direct contact electric shock accidents.

[0004] In the actual operation and maintenance process, many links require checking the working status of the battery box when the equipment is powered. For example, checking the operating status of the battery box fan and checking the condensation of the battery box for outdoor equipment in seasons with high humidity.

[0005] In summary, the presence of DC cables between battery boxes increases the risk of electric shock for operation and maintenance personnel.

[0006] In addition to causing electric shock due to direct contact, the exposed cables outside the battery box also pose a risk of being damaged by rats and other rodents. In large-scale energy storage power stations, the battery boxes are arranged in prefabricated cabins. Because of the compact space, it is impossible to set up rat shields, so rodents can enter when the cabin door is opened. The line of sight is blocked by battery brackets, battery boxes, high-voltage boxes, etc., so it is difficult to find rodents once they enter the cabin. Rats have a hobby of chewing hard objects, so it is also necessary to prevent wires and cables from being bitten by rats.

[0007] Whether the battery boxes are arranged in indoor or outdoor prefabricated cabins, they are arranged in rows and columns through the rails on the battery bracket. If a battery box fails, it needs to be pulled out for inspection or replacement. When the upper battery box needs to be pulled out, it is easy to fall, and the falling process will cause physical damage to the cables and harnesses of the lower battery box. Utility Model Content
