What is an operation ticket in the power system, the process of the operation ticket and the precaut

The operation ticket is the safety guarantee for the operation of the power operation workers, and is an important part of the "two votes and three systems" for the safe production of electric power.

According to the regulations, every operation task of the power plant substation (except for the single operation of pulling and closing the switch and removing the only set of grounding wires in the whole plant) must first fill in the "Operation Ticket". The "Operation Ticket" must list the contents of each operation in order. The "Operation Ticket" shall be filled in and signed by the operator with the qualification of duty, reviewed and signed by the guardian, reviewed and signed by the squad leader, and signed by the duty leader for approval.

Operation Ticket" is not allowed to be altered. Before performing the operation, the operator and the guardian must also carry out the "simulation operation" on the simulation board to ensure that the operation ticket is correct. When operating, the "Operation Ticket" is held by the guardian, the guardian "sings the ticket", the operator "recites", and the guardian issues "right!

Execute! ", the operator can carry out the operation. After each operation, the guardian must "tick" in time.

Skipping and missing items are not allowed in the operation. If there is a doubt, stop the operation and eliminate the doubt before continuing. After the implementation of the "Operation Ticket" is completed, it should be reported to the superior in a timely manner.

Operation Ticket" stamped with the "executed" seal and kept for three months.

That's pretty much it. There are too many details, and there is a very thick book.

Including the work ticket number, the person in charge of the work, the members of the work class, the place and content of the work, the planned working time, the end time of the work, the scope of the power outage, the safety measures, the work permit holder, the work ticket issuer, the work ticket approver, the comments after the power transmission, etc.

The work ticket is filled out in duplicate by the person who issued the work order. Generally, it will be handed over to the operation duty office on the day before the start of construction, and the person in charge of the construction will be notified.

A work class can only assign one missing work task at the same time, and one work ticket will be issued. The operating range is limited to one electrical connection section. The electrical connection part refers to the general term of the equipment connected to the busbar and installed in a distribution device room, switch site and transformer room, and connected in the same electrical circuit.

Including circuit breakers, disconnectors, voltage transformers and current transformers, etc.

If several tasks need to be assigned to the same work shift, in order to prevent accidents caused by making mistakes in the time, place and safety measures of work, only one of the tasks can be assigned first, and a work ticket will be issued to the person in charge of the work.

After the task is completed and the work ticket is recovered, the second task will be assigned and the second work ticket will be issued to the macro file. After receiving the work ticket, the duty officer should check whether the safety measures proposed on the work ticket are complete.

The work ticket is the written basis and safety license for maintenance operations on the power production site, equipment and system, and is a written safety agreement jointly held and complied with by both maintenance and operation personnel. The operation ticket is the written basis and safety license for the operation of the production equipment and system.

In the power production site, equipment, systems engaged in overhaul, maintenance, installation, transformation, commissioning, testing and other work, must implement the hazard point analysis pre-control system, work ticket system, work lead sales permit system, work guardianship system, work interruption, transfer and termination system.

To operate on power production equipment and systems, it is necessary to implement the pre-control system of hazard point analysis, the operation ticket system and the operation monitoring system.

The operation ticket refers to the written basis for electrical operation in the power system, including the dispatching instruction ticket and the substation operation ticket. The operation ticket is the main measure to prevent misoperation (mis-pulling, mis-closing, pulling with load, closing the isolation switch, closing with ground wire, etc.).

The following work can be done without an operation ticket: (1) Accident handling. (2) Single operation of pulling and closing the circuit breaker. (3) Pull the grounding switch or remove the only set of grounding wires in the whole plant (institute).

The work of filling out the first type of work ticket is: the work on high-voltage equipment requires a total or partial power outage; The work on the secondary wiring and lighting circuits in the high-voltage room requires the high-voltage equipment to be powered off or safety measures to be taken.

The work of filling out the second type of work ticket is: live work and work on live equipment housing; The low-voltage distribution panel, distribution box, and power supply trunk of the control panel work; Working on the secondary circuit, the high-voltage equipment is not powered off; Rotating generators, simultaneous work on the excitation circuit of the condenser or the rotor resistance circuit of the high-voltage motor; The off-duty personnel use insulating rods and voltage transformers to phase or use clamp ammeters to measure the current of the high-voltage circuit.

The operation ticket refers to the written procedure for the operation of the equipment in a certain order according to the specific content of the operation instructions issued and the technical principles of the equipment in accordance with the "Safety Regulations" and the technical principles of the equipment in order to ensure the correctness of the operation of the electrical equipment.

The operation ticket shall be filled in by the operator according to the requirements and format. Each operation ticket can be filled in one operation ticket, and each operation ticket can only be filled in one operation task. The operation task should be filled in concisely and clearly, and the corresponding explanation should be filled in the remarks column.

The operation ticket must write the dual name of the equipment, that is, the Chinese name of the equipment and the number recognized by the dispatch, and the operation ticket must be filled in according to the terminology specified in the scheduling.

The operation ticket used in the operation of the power plant is generally not divided into ticket types, except for a single operation generally with the operation ticket, which is a system formulated to ensure the correct operation to avoid misoperation accidents, if you must divide the ticket type, I think it should be divided into fixed mode operation and non-fixed mode operation, the so-called fixed mode, that is, every time the operation task, the operation project content, procedures and requirements are exactly the same, and the equipment state before and after each operation is basically the same. This kind of ticket can be automatically generated mode (from a safety point of view, do not want to be automatically generated, because filling in the operation ticket before operation is a simulation of the operation of the exercise operation of the thinking process, to avoid misoperation is beneficial, but the automatic generation of operation ticket, can reduce the workload of the operator), power plant operation, the equipment state before the operation is not the same, and the state after the operation is not necessarily exactly the same, in this case, the content of the operation ticket program requirements will be different, you can not use the fixed operation ticket, It needs to be filled in by the operator before operation.

Fill in the "Power Line Operating Regulations" of the power supply company.

The general requirements for filling in the operation ticket are as follows:

1. The operation task must be correct and clear.

2. The filled in device must use a double number.

3. Must use fountain pen blue and black ink (may no longer be required).

4. The operation steps must be filled in order and must not be reversed.

5. Only one operation step is allowed to be filled in per row.

6. The equipment name number and operation verb are not allowed to be modified, and the original handwriting must be kept clear and legible when modifying.

7. The operation ticket should be filled in by the operator, reviewed by the guardian, reviewed by the squad leader, and approved by the chief (director). Signatures are not allowed.

8. There will be some details in each unit.

The work ticket is overhauled and used. The self-ticketing is used when the equipment is started and stopped, and the system is switched. Operate.

The ticket is filled in by the operator, reviewed by the guardian, and approved by the dispatcher. The work ticket shall be filled in by the person in charge of the maintenance work or the person issuing the work ticket, and shall be approved by the operation attendant. How the dispatcher will arrange for the ticket pick-up.

In principle, both votes can be regarded as life votes. It plays a very important role in safety management and can effectively avoid the occurrence of three violations.

The electrical operation ticket is one of the important contents of the "two votes and three systems". The general requirements in the implementation of the electrical operation ticket system are: (1) Do not operate the operation scope of the ticket shall not be arbitrarily expanded.

In accordance with the provisions of the "Electrical Safety Work Regulations", the following electrical operations are allowed without operating tickets. 
