Four measures to tighten the power line, what does it mean to tighten the line in power engineerin

It is safety, technical, organizational and environmental protection measures.

Safety precautions. Technical measures.

Organizational measures. The construction plan is referred to as the case of three measures.

The unfolding of wires and ground wires is to connect wires or ground wires from one tower to another. Tight wire refers to the design sag after the connected ground wire is lifted into the air.

1. There should be a special person to command and unify the signal for the work of pay-off, withdrawal and tight-line work, and ensure smooth communication and strengthen supervision. Before work, check whether the tools and equipment for pay-off, wire removal and wire tightening are in good condition.

2. When crossing various lines, railways, highways, rivers, etc., the consent of the competent department should be obtained first, and safety measures should be taken, such as setting up a reliable crossing frame, sealing navigation, road closure, and setting up a special person holding a signal flag to guard the intersection.

3. Before tightening the wire, check whether the wire is hung without obstacles, and check whether the wiring pipe or terminal head and the pulley, cross arm, tree branches, houses and other places are stuck when the wire is tightened. If there is a jam or hanging phenomenon on the guide and ground wire, the wire should be loosened and then treated. When processing, the operator should stand on the outside of the stuck line, and use tools, ropes, etc. to pry and pull the wire.

It is strictly forbidden to pull or deduce the wire directly by hand.

4. When pay-off, withdrawing and tightening the line, personnel shall not stand or straddle the inner corner side of the traction rope and the inner corner side of the conductor and the unfolded guide and ground coil and the vertical below the traction rope or overhead line to prevent accidental scratching during the line running.

5. Before tightening the line and withdrawing the line, the pull wire, pile anchor and tower should be checked. If necessary, the pile anchor should be reinforced or a temporary rope should be added.

6. It is strictly forbidden to loosen the wire by suddenly cutting the guide and ground wire.

Four measures for the power industry:

The first is to convene a mobilization meeting to organize all line protection units to conscientiously study and implement the laws, regulations and the spirit of superior documents for the protection of power facilities, strengthen the sense of responsibility of line protection workers, and formulate detailed line protection plans and division of responsibilities;

The second is to use television stations, radio and other national propaganda to publicize the knowledge of power facility protection, and organize employees to go deep into the fields, farmers' markets and other places to distribute a large number of power facilities protection regulations, rural electricity safety and other related publicity materials, so that farmers and users are aware of the importance of protecting power facilities;

The third is to divide the responsibility section for the protection of power facilities in accordance with the principle of "who is in charge and who is responsible", implement the responsibility to the people, strictly implement the inspection system of power facilities, improve the quality of inspection and clean-up work, and realize the controllability and control of risk factors that threaten the safety of power facilities;

Fourth, it is necessary to strengthen communication and contact with the public security departments, adopt a joint police-enterprise approach to protect power facilities, and actively assist the public security organs in severely cracking down on illegal and criminal acts of sabotage and theft of power facilities.

1. Organizational measures.

2. Security measures.

3. Technical measures.

4. Environmental protection measures.

1. Three checks:

1. Check the status, 2; Check the attire, 3; Check the device.

2. 3rd Communication; 1. Assign tasks, 2; Traffic security 3; Delivery technology. Clause.

1. After the station shift meeting, all construction workers must pass through the testing area before entering the construction site;

Clause. 2. When passing through the detection area, all personnel must first pass through the single-plank bridge, and then the high-altitude workers must climb the "climbing area", and the safety belt must be fastened to the side guardrail on the high-altitude platform, and it is strictly forbidden to jump down from the frame when falling into the "climbing area"; Non-high-altitude workers are prohibited from climbing the "climbing area".

Clause. 3. When passing through the testing area, you should not make noise or push, and your body should remain upright when walking on a single-plank bridge, and you should not look around or talk with others.

Clause. 4. Any person who does not pass the safety inspection area and enters the construction site without authorization shall be punished according to the violation and stop working on the same day.

Clause. 5. The safety officer of the project department is responsible for supervising the construction workers to pass through the safety inspection area, and if it is found that it does not meet the requirements, it will be reported in time and shall not enter the construction site.

"Three measures and one case": construction organization measures, technical measures, safety measures and construction operation plan.

1. Organizational measures.

It refers to the nature of the work, careful planning, timely organization, after receiving the work task, the relevant person in charge conscientiously performs the work duties, strict operation system, guardianship system, and the implementation of the operation step by step.

2. Technical measures.

It is required that the pole should be commanded by a special person, and a special person should be set up to guard the pole in residential areas and traffic roads. Before work, the verification report of the crane and the driver's special operation certificate should be checked to see if it is qualified, and it is strictly forbidden to use unqualified cranes.

When erecting the pole and trimming the pole pit, there should be measures to prevent the shaft from rolling and tilting, and the staff under the pole should wear safety helmets. In the pay-off, withdrawal and tightening work, there should be a special person to unify the command, unify the signal, and check whether the tightening tools and equipment are in good condition.

3. Security measures.

It is necessary to strictly implement the "State Grid Corporation Electric Power Safety Work Regulations", fill in the standardized operation instructions, the construction site safety measures card, implement standardized operations, and implement various organizational and technical measures to ensure safety on site.

4. Construction operation plan.

Including the operation organization, specific working group division of labor and work tasks, preparations, construction methods and operating procedures, process standards and precautions, etc.

The three measures of electric power construction refer to organizational measures, technical measures, and safety measures.

When an electric power enterprise carries out any engineering construction, equipment installation, commissioning, start-up, overhaul and other work, it shall formulate three major measures to ensure work safety, namely: organizational measures, technical measures and safety measures.

Organizational measures include the organizational structure and the rules and regulations that must be followed in the course of work.

Technical measures include the provisions of the relevant procedures and systems (including process requirements) that must be implemented and the specific technical measures that must be implemented. The system that must be implemented, such as the development of construction work instructions, maintenance management system, operating procedures, etc.

Security measures have different contents in different occasions, and they are mainly divided into three categories.

1) Among the three major measures of engineering and operation, safety measures mainly refer to the general aspects. For example, the relevant content of the "two votes and three systems" should be implemented, and the staff should use protective facilities correctly, wear safety protective equipment, fire work requirements, on-site fire prevention measures, construction operation scope, safety supervision, safety training before operation, and so on.

2) Specific safety measures that must be implemented before construction work. Such as:

The first type of safety measures that must be carried out by the power plant's work ticket: power outage, power inspection, installation of grounding wires, installation of signs and shielding.

The safety measures that must be implemented for the first type of work ticket of the power line: pull the switch and the knife switch, and install the grounding wire at both ends of the working range.

The safety measures that must be taken for the thermomechanical work ticket: according to the different maintenance equipment, the relevant provisions are clearly stipulated in the "Electrical Safety Work Regulations" (thermomechanical part).

3) Personnel should implement safety measures during construction operations. Such as: maintain a safe distance from live equipment, general monitoring and full-time monitoring requirements at work, etc.

(1) Before work, fill in, issue and handle work tickets correctly in accordance with relevant regulations. The person in charge of the work should carefully explain the work content, safety measures, dangerous points and safety precautions to the construction personnel, and require each construction personnel to be clear and sign for approval.

2) Prepare standardized work instructions before construction, and be approved by relevant leaders and departments, do a good job of danger analysis and pre-control measures, and each construction personnel should be familiar with the work instructions before operation.

3) Before construction, each operator shall be trained in on-site safety technical regulations, and only after passing the examination can they be listed for work.

4) Be familiar with the drawings, find out and solve the problems in the design of the drawings, and explain to the technical personnel involved in the construction.

5) The sequence of electrical installation and commissioning and the coordination with civil engineering, and the construction equipment and labor required are proposed.

6) The project manager, chief engineer, safety officer, technician, construction team leader and other relevant personnel shall go deep into the site before construction, verify and remove the live parts around the site, the walking route and working position of the crane, and the objects that pose obstacles to the construction, identify the unsafe factors in the construction, and formulate reliable safety precautions. The safe distance from live equipment is, 35kV: m, 110kV:

m, 220kV: m.

7) During the construction, the construction shall be carried out in strict accordance with the requirements of the construction organization design and relevant technical specifications and standards.

8) The construction site should be installed according to the actual situation to install and hang a variety of signs, the two ends of the barrier should be tied firmly with the fixed objects, the fixed distance between the middle binding is not more than 6 meters, and the lower end of the barrier can be tied with heavy objects to prevent strong winds from blowing. It is strictly forbidden for staff to move or remove fences and signage during work. Upstairs is right, I didn't know very well before, I have been working in Jiuzhou Qiangui Electric Power Design for a long time, and the old designer will also teach us a lot of things, I hope my supplement combined with the knowledge upstairs can help you,
