Description

Technical Field

[0001] The invention relates to the technical field of solid-sealed poles, and in particular to an intelligent solid-sealed pole for a coal mine safety system. Background Art

[0002] During the underground coal mining process, the air contains explosive gases such as gas, and the electrical equipment is dangerously high temperature or has sufficient spark energy. Therefore, the flameproof electrical equipment casing and components used in explosive and dangerous places such as coal mines are undoubtedly one of the most important factors related to underground safety. Therefore, mining electrical equipment is required to achieve both flameproof performance and electrical performance. With the development of science and technology, flameproof electrical control cabinets are used in the market for safe underground coal mining operations.

[0003] However, the explosion-proof electrical control cabinets for coal mines currently on the market generally control each connecting line separately, which makes the operation complicated and the circuit-breaking operation cannot be well controlled. The circuit-breaking operation needs to be performed separately to continue to stop operation or maintenance. If one of the operation steps is wrong, it will cause a major safety accident.
