[0002] In the early operating products of 550kv extra-high voltage power transmission and transformation GIS circuit breakers, the breaking current capacity of the arc-extinguishing chamber is mostly 50k amperes. With the continuous increase of the grid capacity of the national extra-high voltage power transmission and transformation, it is necessary to synchronously increase the breaking capacity of the circuit breakers on the extra-high voltage power transmission and transformation lines by more than 15%.

[0003] When carrying out capacity increase transformation on the circuit breaker, it is necessary to replace the arc-extinguishing chamber of the circuit breaker as a whole. However, as the core key component of the circuit breaker, the large-capacity arc-extinguishing chamber is very expensive. From the start of production and manufacturing until it is transported to the construction site of the substation for replacement, the duration is relatively long. Ordinary wooden box packaging cannot meet the technical requirements for the transportation and storage of large-capacity arc-extinguishing chambers. During the entire equipment transformation period, if the packaging is damaged or cracked due to external force, the overall structure of the arc-extinguishing chamber will be invaded by water vapor in the air, resulting in a decline in the performance of the overall insulating parts; if the situation is serious, dust and rain will enter, resulting in the arc-extinguishing chamber being unusable or directly damaged, causing irreversible losses to the power transmission and transformation equipment and leaving serious quality hazards.
