The electric control box controls the electrical safety of the circuit, and the safety of electricity is also an important issue that everyone pays attention to. Today's Xiaobian and everyone's content is also closely related to this issue, the introduction is about the external line protection of the electric control box.
1. When the relevant regulations are not met, insulation isolation measures shall be taken, and eye-catching warning signs shall be hoisted; when the protective facilities are installed, they must be approved by the relevant departments, and temporary power outages or other reliable safety technical measures shall be adopted. There are electrical engineering technicians and full-time security personnel to supervise.
2. The small safe operating distance between the perimeter of the construction in progress and the sideline of the external electric overhead line shall comply with the provisions. The ramp of the upper and lower scaffolding shall not be located on the side with the external electric line.
3. When excavating trenches near the overhead line of external power, it is necessary to take reinforcement measures with the relevant departments to prevent the poles of the external electric overhead lines from tilting and overhanging.
4. The crane is strictly prohibited from working over the overhead line of unprotected external power. When hoisting near the external electric overhead line, the safety distance of any part of the crane or the edge of the suspended object at the time of the large deflection and the edge of the overhead line shall comply with the regulations.
5. The distance between the edge of the trench at the construction site and the edge of the trench of the external buried cable should exceed half a meter.
6. When the motorway at the construction site crosses the overhead line of the external power, the vertical distance between the low point of the overhead line and the road surface shall comply with the regulations.
7. If the protective measures cannot be realized, it is necessary to negotiate with the relevant departments to take measures such as power outage, migration of external power lines or change of project location. Construction without such measures is strictly prohibited.
8. Construction in progress shall not be constructed directly under the control box, erecting work sheds, building living facilities or stacking components, racks, materials and other sundries.
The above is the relevant regulations of the control box for external line protection. This system problem is very noteworthy in any aspect. Only on the basis of this system can the construction be carried out normally.
