Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a safety isolation device for energy storage high-voltage batteries. Background Technology

[0002] With the increasing global demand for renewable energy and efficient energy storage technologies, energy storage systems are being used more and more widely in the fields of power, transportation, and industry. Among them, high-voltage batteries (such as lithium batteries, sodium-sulfur batteries, and flow batteries) have become the preferred choice for large-scale energy storage systems due to their high energy density, long lifespan, and fast charge and discharge capabilities. However, as battery voltage levels continue to increase, the safety issues of high-voltage batteries for energy storage have become particularly prominent.

[0003] In high-voltage battery systems for energy storage, safety isolation devices are key components for ensuring the safe operation of the system. Their main function is to establish a good protective effect between the high-voltage and low-voltage parts of the battery system. However, the existing safety isolation devices have relatively simple structures and functions, and can only perform simple electromagnetic interference protection and electrical isolation. They are clearly insufficient in terms of overall environmental adaptability, and their maintainability also needs to be improved. Therefore, those skilled in the art provide a safety isolation device for high-voltage batteries for energy storage to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a safety isolation device for high-voltage energy storage batteries. During use, multiple protective layers are incorporated to provide corrosion resistance, moisture resistance, high-temperature resistance, and insulation, ensuring that the internal structure is not affected by external environmental factors. An extended maintenance structure is provided, allowing for engagement between adjacent connecting base plates via slots and blocks. Furthermore, insulating isolation layers on both sides of the pressure plate ensure internal safety during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety isolation device for energy storage high-voltage batteries, including an extended maintenance structure, a protective structure at the upper end of the extended maintenance structure, a main body inside the protective structure at the upper end of the extended maintenance structure, and a high-voltage connector and a low-voltage connector respectively provided at the center of the upper end surface of the main body near the two side edges;

[0006] The protective structure includes a shell, a first protective layer is disposed inside the shell, a second protective layer is disposed inside the first protective layer, a third protective layer is disposed inside the second protective layer, and a fourth protective layer is disposed inside the third protective layer.

[0007] The extended maintenance structure includes a connecting base plate, with slots and blocks respectively provided at the center of the upper surface of the connecting base plate near the four edges; connecting grooves are provided at the center of the front and rear inner side walls of the housing; a pressure plate is provided at the upper end of the main body; the two ends of the pressure plate are respectively slidably connected to the inside of the two connecting grooves; and an insulating isolation layer is provided on both sides of the pressure plate.

[0008] Through the above technical solution, when in use, by setting up multiple protective layers, the whole body has corrosion resistance, moisture resistance, high temperature resistance and insulation, ensuring that the internal body will not be affected by external environmental factors during use. By setting up an expansion and maintenance structure, when in use, the slots and blocks between two adjacent connecting base plates are engaged and locked together. At the same time, by setting up insulating isolation layers on both sides of the pressure plate, the safety of the internal body during use can be guaranteed.

[0009] Furthermore, each of the two sides of the pressure plate is provided with a placement hole near its two ends, and a spring is fixedly connected inside each of the four placement holes. A top bead is fixedly connected to the other end of each of the four springs. Multiple limiting holes are provided at the center of the two inner side walls of the two connecting grooves, and the top bead and the limiting hole are mutually compatible.

[0010] With the above technical solution, during use, the top ball and spring work together to engage with the limiting hole for positioning, which facilitates the restriction and positioning of the main body, ensuring stability after placement and preventing internal shaking.

[0011] Furthermore, handles are fixedly connected to the center of the upper end face of the main body near the two side edges respectively;

[0012] The above technical solution facilitates the removal and insertion of the main body from and into the shell.

[0013] Furthermore, the upper end of the protective structure is provided with a top cover, and the top cover is detachably connected to the housing;

[0014] The above technical solutions facilitate internal inspection and maintenance.

[0015] Furthermore, the insulating layer is made of ceramic.

[0016] The above technical solution ensures sufficient insulation strength between the high-voltage end and the low-voltage end, preventing the generation of electric arcs during use.

[0017] Furthermore, the materials of the first protective layer, the second protective layer, the third protective layer, and the fourth protective layer are polycarbonate, epoxy resin, polyimide, and polytetrafluoroethylene, respectively.

[0018] The above technical solutions enable the whole system to have good corrosion resistance, moisture resistance, high temperature resistance and insulation.

[0019] Furthermore, the card slot and the card block have the same shape;

[0020] The above technical solution facilitates the connection and combined use of two adjacent extended maintenance structures.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up a protective structure and setting up multiple protective layers, the whole body has corrosion resistance, moisture resistance, high temperature resistance and insulation, ensuring that the internal body will not be affected by external environmental factors during use.
