The sign of the power distribution room is a yellow triangular bottom plate with a lightning bolt on it. As shown in the following figure:
The power distribution room refers to the indoor power distribution place with low-voltage load, which mainly distributes electric energy for low-voltage users, and is equipped with medium-voltage incoming lines (with a small number of outgoing lines), distribution transformers and low-voltage power distribution devices.
the facilities of p>1kV and below voltage level equipment are divided into high-voltage distribution room and low-voltage distribution room. The high-voltage distribution room generally refers to the 6 kV-1 kV high-voltage switch room; Low-voltage transformer room generally refers to the 4V transformer room for 1kV or 35kV stations. The entry introduces the composition, design specification and safety system of the distribution room.
safety system:
1. The electrician on duty must have the necessary electrician knowledge, be familiar with the safety operation procedures, and be familiar with the performance and operation methods of various equipment in the power supply system and distribution room. And have the ability to take measures under abnormal circumstances.
2. The electrician on duty should have a high sense of responsibility, strictly implement the patrol system on duty, the working ticket system for switching operation, the management system for safety appliances and fire fighting equipment, and the access system.
3. Persons who are allowed to patrol high-voltage equipment and act as guardians alone shall be approved by the leaders of the power department.
4. No matter whether the high-voltage equipment is charged or not, the personnel on duty shall not move or go straight across the barrier. If there is a fence that must be moved, there must be a guardian present, and the safety distance should be met when the equipment is not powered off.
