The two votes refer to: the work ticket and the operation ticket.
Work tickets are used for the maintenance of electrical equipment. Before maintenance of electrical equipment, maintenance personnel should request work tickets in advance to ensure safety.
Operation tickets are used for the operation. The use of operation tickets is intended for operators to avoid operation errors and ensure safe operation.
How important is the use of work tickets in power plants?
The two-way system is a system for electrical work. Two votes: work ticket, operation ticket; three systems: shift transfer system, patrol inspection system and regular equipment testing rotation system. This system is generally used in the works of hydroelectric power stations, cethermal power stations and substations. This content is also stipulated in the thermal and mechanical parts of the “Regulations on safety of work in the electrical industry”.
Legal basis:
"Regulations on work safety in the electrical industry"
Article 3: This regulation applies to production, transformation, transport, distribution and production of electricity. agricultural equipment in use. All personnel working on consumer electrical and electrical equipment (including infrastructure installation personnel). Each unit can formulate additional provisions based on on-site conditions and implement them after approval of the head (chief engineer) in charge of production of the factory (office). The so-called used electrical equipment refers to electrical equipment that is fully or partially charged and is energized when used.se. Article 4 Electrical equipment is divided into two types: high voltage and low voltage: high voltage: equipment with ground voltage above 250 V; low voltage: equipment with a ground voltage of 250 V or less.
Article 4 Electricians must meet the following conditions: 1. Be evaluated by a doctor and not suffer from an illness preventing work (physical examination approximately once every two years). 2. Possess the necessary electrical knowledge and know the relevant parts of the “Safety Working Procedures in the Electrical Industry” (electrical part, power line part, thermal and mechanical part of power plants and substations) according to their tasks and nature of work, and pass the qualified examination. 3. Learn emergency first aid (Appendix G), especially first aid for electric shock.
Article 6 Electrician personnel mustit takes an exam for this procedure once a year. If electrical work is interrupted for more than three consecutive months for any reason, you must review this procedure and pass the exam before you can return to work. Personnel participating in actual operations must undergo special training, pass the exam and be approved by the chief before they can participate in the work.
The work ticket provides the written basis and security license for service personnel to perform inspection, maintenance, installation, modification, debugging, testing and other (collectively referred to as “maintenance work”) on electricity production. sites, equipment and systems. This is a written safety agreement held jointly and obligatorily respected by maintenance and operations personnel.
