Measures for the administration of power supply safety working tickets and operation tickets
The first chapter working ticket
The first section substation and line working ticket general part
One: When carrying out normal maintenance of power supply equipment, safety measures should be taken when necessary.
, a working ticket should be used.
Article 2 Ordinary working tickets are divided into one or two working tickets for substations and power lines.
First, a work ticket. According to the safety regulations, the use format is as follows:
Fill in the working ticket:
The work of the working ticket is:
() Working on high-voltage equipment requires total or partial power failure;
() The secondary wiring and lighting in the high-voltage room need to cut off the power supply of high-voltage equipment or take safety measures.
The work of filling out two working tickets is as follows:
() Live working and working on the shell of live equipment;
() Work on the control panel, low-voltage switchboard, distribution box and power supply trunk line;
() It is not necessary to cut off the high-voltage equipment when working on the secondary wiring circuit;
() Working on the excitation circuit of rotating generator, synchronous camera or rotor circuit of high-voltage motor.
() Non-on-duty personnel are on duty to phase with insulating rods and voltage transformers or to measure high-voltage circuit current with clamp ammeter.
A, the use of power line working ticket:
The job of filling in the working ticket is:
() working on power outage lines (or primary power outage lines in double-circuit lines);
() Work on the distribution transformer platform or in the distribution transformer room with total or partial power failure.
The so-called total power failure means that all power supply lines to the transformer station or distribution transformer room have been completely disconnected.
The work of filling out two working tickets is as follows:
() Live working;
() working on the electric wire tower;
Work on the distribution transformer workbench or in the distribution transformer room.
Article 3: The working ticket shall be filled out by the issuer. Sometimes, in order to reduce the workload of the work ticket issuer, the person in charge of the work can also fill in the work ticket of the class (group).
Article 4: The working ticket shall be filled in with pen or ballpoint pen in duplicate. It should be filled in correctly and cannot be modified at will. If individual words need to be revised, they should be written clearly. The working ticket can only be modified up to 20 words.
Article 5 The working ticket shall be filled in a language that can accurately express the meaning and meet the standard of Putonghua.
Article 6: The personnel listed on the working ticket shall check the working ticket according to their duties, with complete signatures and neat handwriting.
Article 7: The issuer of the working ticket shall be the person approved and announced by our company. The working ticket issuer shall not concurrently be the person in charge of the work.
Article 8: Issuance of working tickets.
The working ticket shall be issued by the issuer, and the working ticket filled out by the person in charge of the work must also be issued by the issuer.
In general, the working place on the working ticket is limited to an electrical connection part (bounded by the fracture of the circuit breaker). If the construction equipment belongs to the same voltage and is located on the same floor, and the power supply is stopped at the same time, and the live conductor will not be touched, a working ticket is allowed for several electrical connection parts.
Under the following circumstances, the person designated by the company who has the right to issue working tickets and the personnel on duty shall perform the work permit procedures. The working ticket issuer is only responsible for the necessity of the work, whether the work is safe and whether the safety measures listed on the working ticket are correct and complete. Before starting work, the guardian (the person in charge of the construction unit) shall conduct safety education for the staff and explain the matters needing attention.
() Foreign units with legal personality come to the substation to contract equipment maintenance, anticorrosion or installation.
() Infrastructure construction needs the running equipment to stop running.
() The installation unit will deal with the defects of the newly invested equipment.
One, a substation or a line all power outage maintenance, can issue a working ticket, but to specify the work content. When several teams are working at the same time, the working ticket can be sent to a general manager, and only the person in charge of each class can be filled in the column of working class members. ,
Measures for the administration of power supply safety working tickets and operation tickets
Article 9: One of the two working tickets must always be kept in the workplace, and the person in charge of the work shall be responsible for it, and the other one shall be handed over according to the value. The personnel on duty shall record the work ticket number, work task, allowable start time and completion time in the operation record book.
Article 10: person in charge of work (guardian)
, approved by the bureau leadership announcement personnel.
When an external unit with legal person qualification contracts civil construction, equipment maintenance, installation, anti-corrosion or debugging in a substation, the external unit shall designate a person in charge (guardian) and submit the list to the company's safety supervisor for safety qualification examination in advance, and the safety supervisor will forward it to the substation after passing the examination.
Change of the person in charge of the work:
During the work, the person in charge of the work temporarily leaves the site for several hours, the working ticket issuer should be replaced by a new person in charge of the work, and the two working heads should make necessary handover. The person in charge of the work can only be changed once. The change of the person in charge of the two working tickets is recorded in the "Remarks" column.

, the working ticket qualification rate (%) is calculated on a monthly basis, and the calculation formula is as follows:
Qualified ticket
Qualified rate = ———————————×%
Unqualified tickets+qualified tickets+other tickets,
