In order to further improve the mechanical and electrical management level of each mine and ensure the safe and stable operation of the power supply system, from November 23 to 24, m88 review Mining Company held the second special training class on relay protection setting for more than 30 mechanical and electrical professional technicians , on-site electricians and others participated in the training.
“When a fault occurs in the power supply system, the protection device closest to the fault point should act first to remove the fault, while other fault-free parts of the power supply system should continue to operate. Actions that meet this requirement are called selective... ”
In class, the teacher focused on the four key points of coal mine power grid protection difficulties, current protection, leakage protection, and power grid fluctuation protection. Combined with the actual power supply management of mines, the teacher systematically explained the three factors that affect the safety and reliability of the power grid, and the protection difficulties of eliminating safety hazards. Knowledge such as over-current protection setting value calculation and conventional leakage protection setting value setting is highly targeted and practical, and plays a role in answering questions.
“When I encountered relay protection setting calculations before, sometimes I still had some doubts. This training was very timely, comprehensive, and thorough. It allowed us to know both what it is and why it is, so that we can do a good job in electromechanical work in the next step. The work has laid a solid foundation," said Yuan Jihuan, technician of the transportation team of Hanjiawan Coal Company.
Carrying out this special training has enriched the professional knowledge reserves of the participants and improved everyone’s enthusiasm for learning and technical skills. Everyone expressed that they would apply the knowledge learned in the classroom to actual work, further improve the safety and stability of the power supply system, strive to play a greater role, and use practical actions to assist mine safety production.
At a time when the 100-day safety production standardization and labor competition activities are in full swing, carrying out this special training on mechanical and electrical management will effectively promote the skill improvement of personnel in each position, further ensure the continuous and stable improvement of mine safety production, and sprint for the company. In the fourth quarter, we will fight the "final battle" well to create good conditions.
