Introduction
Interpretation of Technical Specifications for Long-distance Power Supply System of Fully Mechanized Coal Mining and Top-coal Caving Working Face
1. Background of Standard Formulation
With the continuous advancement of coal mining technology, fully mechanized coal mining and top-coal caving working faces occupy an important position in coal mine production. However, in actual operation, due to factors such as complex equipment layout, frequent movement and long power supply distance, traditional power supply methods are difficult to meet the needs of efficiency and safety. In order to solve these problems, GB/T 37814-2019 "Technical Specifications for Long-distance Power Supply System of Fully Mechanized Coal Mining and Top-coal Caving Working Face" came into being, aiming to provide coal mining enterprises with a scientific design basis for long-distance power supply systems.
2. Comparison of standard frameworks
| Chapter | Content Overview | Keywords |
|---|---|---|
| 1 Scope | Specifies the design requirements and applicable scope of the long-distance power supply system. | Design requirements, fully mechanized mining and caving, long-distance power supply |
| 4 General requirements | Details the general principles and power supply requirements of system design. | System design, power supply requirements, equipment selection |
| 6 Technical requirements for equipment selection | Specifies the technical parameters of mobile substations, combination switches and other equipment. | Mobile substation, combination switch, frequency converter |
3. Implementation suggestions
Case analysis:When a coal mine applied this standard, it significantly reduced the power loss of the power supply system by optimizing the location of distribution points and equipment selection. For example, the mobile substation was arranged in the widened area, and special frequency conversion cables were used to effectively reduce voltage losses.
Suggestions:Enterprises should focus on the following points during implementation:
- Fully consider the working face environmental conditions and reasonably select equipment;
- Optimize the power supply line design to ensure that the voltage loss is within the allowable range;
- Regularly maintain electrical equipment to ensure safe operation of the system.
