Description

Technical Field

[0001] The present application relates to the technical field of explosion-proof electrical equipment for coal mines, and in particular to a fault judgment device for explosion-proof electrical equipment for mines. Background Art

[0002] With the rapid development of intelligent coal mines, electrical equipment in coal mines is developing towards integration, modularization and miniaturization. Most electrical equipment uses PLC control systems. The existing fault handling of electrical equipment in coal mines is mainly divided into the following two technologies: 1. When handling programmable controller faults in non-hazardous areas, judge and handle them by observing PLC indicator lights, HMI touch screen, host computer configuration or by computer monitoring programs when the program is open; 2. When handling electrical equipment with programmable controllers in coal mines, the fault can only be judged and handled by replacing modules or components.

[0003] When handling electrical equipment with programmable controllers in coal mines, since coal mines are dangerous areas, the Coal Mine Safety Regulations and the Electricity Operation Regulations stipulate that "live work is strictly prohibited in coal mines". Therefore, when handling electrical equipment with programmable controllers in coal mines, it is illegal to open the cover while it is live, and live operation may cause gas explosion, which brings certain difficulties to the troubleshooting of electrical equipment with programmable controllers.

[0004] When electrical equipment in coal mines is energized, the overall operation, stop status, overcurrent and leakage faults of the electrical equipment in coal mines will be displayed on the HMI touch screen installed at the observation window on the door of the explosion-proof electrical equipment. However, the operation status and fault status of programmable controllers, expansion modules, power modules and other integrated electrical components cannot be displayed, making it difficult to determine the fault point.

[0005] When electrical equipment in coal mines is not powered on, the programmable controller has no power supply and cannot observe the working indicator light status and fault status of the PLC through the observation window of the electrical equipment, as well as the working indicator light status of each modular and integrated electrical component to judge whether it is good or bad. Isolation components or anti-interference circuits are added to the programmable controller, expansion module, and integrated electrical components, and a multimeter cannot be used for measurement, detection, and judgment. The fault of the electrical equipment can only be judged by replacing components, which increases the fault handling time and seriously affects coal production.

[0006] With respect to the above-mentioned related technologies, at present, there is a problem of low efficiency in the operation status and fault detection of mining explosion-proof electrical equipment. Summary of the invention

[0007] In order to improve the working efficiency when performing operating status and fault detection on electrical components of mining explosion-proof electrical equipment, the present application provides a fault judgment device for mining explosion-proof electrical equipment.

Then, the other end of the optical fiber is installed in the same way at the free space (gap) between the explosion-proof door observation window of the explosion-proof electrical equipment for mining and the HMI touch screen. The indicator light source of the electrical component of the explosion-proof electrical equipment for mining is transmitted by the optical fiber, and the user can directly observe the state of the indicator light of the electrical component of the explosion-proof electrical equipment for mining through the observation window. When using the detection component, the length of the bellows is adjusted so that the fixed sleeve cover is set on the indicator light of the electrical component of the explosion-proof electrical equipment for mining, the optical fiber abuts against the indicator light of the electrical component of the explosion-proof electrical equipment for mining, and the optical fiber transmits the indicator light source of the electrical component of the explosion-proof electrical equipment for mining to the other end of the optical fiber, so that the user can monitor the indicator light state of the electrical component of the explosion-proof electrical equipment for mining, and improve the working efficiency of the operation state and fault detection of the electrical component of the explosion-proof electrical equipment for mining. The shielding plate is concave, which gathers the light source of the indicator lights of the electrical components of the mining explosion-proof electrical equipment and improves the intensity of the light source transmitted by the optical fiber.
