Participation reward: 2 Wealth. Reward for correct answer: 9 Wealth. Quiz: What types of work require the use of the first type of work order?
1. Work on high-voltage equipment that requires a complete or partial power outage； 2. Work on secondary wiring and lighting circuits in the high-voltage room requires shutting down the high-voltage equipment or taking safety measures
① Work on high-voltage equipment that requires a complete or partial power outage； ② Tasks such as secondary wiring and lighting in high-voltage areas, as well as work on the return path, require the high-voltage equipment to be powered down or safety measures to be taken.
Ahah, check the safety regulations first! According to the latest interpretation of the national standard GB 26860-2011 \"Safety Regulations for Electrical Work in Power Plants and Substations – Electrical Part\", work that requires the complete shutdown or partial shutdown of high-voltage equipment, or the implementation of safety measures, necessitates the use of the first type of work order.
Work on high-voltage equipment that requires a complete or partial power outage. Work on secondary systems and circuits such as lighting requires shutting down high-voltage equipment or taking safety measures. Work on high-voltage power cables that requires a power outage. Other tasks that require shutting down high-voltage equipment or taking safety measures.
1) Those who need to work on high-voltage equipment requires a complete or partial power outage. 2) Work on secondary systems and circuits such as lighting requires shutting down high-voltage equipment or taking safety measures. 3) Work on high-voltage power cables that requires power outage. 4) Other tasks that require shutting down high-voltage equipment or taking safety measures.

Welding and cutting operations in no-fire zones, as well as temporary operations that may generate flames, sparks, and hot surfaces using blowtorches, electric drills, grinding wheels, etc., in flammable and explosive areas.
1. Work on high-voltage equipment that requires a complete or partial power outage； 2. Work on secondary wiring and lighting circuits in the high-voltage room requires shutting down the high-voltage equipment or taking safety measures.
① Those who need to shut down the entire power supply or part of it in order to work on high-voltage equipment; ② Work on secondary wiring and lighting systems within high-voltage areas requires that the high-voltage equipment be shut down or safety measures taken.
Work on high-voltage equipment that requires a complete or partial power outage. Work on circuits such as secondary systems that require the deactivation of high-voltage equipment or the implementation of safety measures, as well as lighting circuits. Work that requires shutting down high-voltage power cables. It is necessary to shut down the high-voltage equipment or carry out other tasks to implement safety measures.
