Description

Technical Field

[0001] The utility model relates to the technical field of chassis, in particular to a large-capacity chassis structure. Background Art

[0002] Explosion-proof chassis have excellent performance and are widely used in instruments, meters, electronics, communications, automation, sensors, smart cards, industrial control, precision machinery and other industries. They mainly play the role of protecting instrument components inside the box.

[0003] The density of components installed inside the chassis is getting higher and higher, and the heat generation is getting higher and higher. The high heat generation can easily cause the leakage of flammable gases inside the internal capacitor components. The leaked flammable gases fill the entire chassis. In the event of electric sparks, the internal gas can easily deflagrate and cause an explosion. A violent explosion can cause the chassis door (cover) to fly off, and even injure people. In order to improve the safety of the chassis, we propose a large-capacity chassis. Utility Model Content
