Description

Technical Field

[0001] The utility model belongs to the field of intrinsically safe substations, in particular to a split intrinsically safe substation. Background Art

[0002] The formation of coal requires millions of years of accumulation, accompanied by continuous crustal movement, which brings the surface material into the ground, and after years of chemical changes, gradually forms coal. Therefore, most coal is buried hundreds of meters underground.

[0003] The mining environment of coal mining is relatively complex, the lighting conditions are poor, and the working environment is relatively poor. Workers need to carry sufficient protective equipment. Therefore, on-site maintenance operations are more difficult. In the mining process, gas is the most common gas. Once gas appears, it seriously affects the personal safety of workers and equipment safety. Therefore, the safety monitoring system plays a significant role in coal mining. The mine intrinsically safe substation, as a key link in data collection and system interaction, plays an important role in the safety monitoring system.

[0004] During the long-term use of equipment, some failures will inevitably occur in components. How to restore operation faster and improve the maintenance efficiency of equipment after a failure is an important task that must be considered. Most of the existing intrinsically safe substations are integrated structures. Once a failure occurs, maintenance personnel need to inspect more components to find out the problem, which greatly increases the difficulty of maintenance. Therefore, we hope to design an intrinsically safe substation with a new structure to solve this problem. Utility Model Content
