On the power transmission line construction project management

Paper Keywords: transmission line construction management
Abstract: Combining practical, focusing on the transmission line construction problems. And further elaborated on transmission line construction management measures and technical measures.


Power Engineering construction management with capital-intensive, technology-intensive, resource-intensive, professional large cross construction and other characteristics, but also by the Engineering design, equipment manufacture, transport equipment and materials procurement, there are many other external factors Engineering order reasonable to plan, organize, coordinate, control and manage all aspects of project construction work, you need to clear the power of modern project management processes that exist in some of the problems and find workable solutions.



A transmission line problems in construction management

1.1 Power management processes in construction problems
First, most Engineering managers and technical personnel, the concept of weak investment returns, lack of awareness of the construction contract, lack of control cost of basic knowledge, resulting in the illusion of control equipment, the price when ordering in the budget estimates, and many ancillary equipment supplied with the host did not be made clear in the contract, the final will have to re-order purchases, the results are often greatly exceeded the control value, but in actual construction management process often there are problems with illegal operations.


1.2 Transmission lines that affect the safe operation of human factors and countermeasures
1.2.1 Transmission Line Project construction area of ​​the problem in the transmission line construction process, the occupation of land compensation and the subsequent maintenance of temporary land issues, has been plagued by power, but by the family business in the land contract system reform, sub-fields to households, the circuit area and the interests of farmers has undergone an obvious conflict, especially for old technology lines for maintenance, renovation, change tower, shift and other projects, the villagers must often take the opportunity to be compensated for the reason, obstruct, delay construction, causing obstruction to the power companies.

1.2.2 Transmission lines are theft, vandalism and other problems in recent years, due to damage to power facilities caused by theft cases increased year by year, of which rural power theft outstanding facilities, and electricity facilities, thefts from the person committing the crime to gang crime, and even the formation of the theft, concealment, transportation, and disposal of stolen goods train in recent years, various large-scale development and construction of industrial parks, urban roads and related infrastructure reconstruction projects have been groundbreaking, so the construction process due to various omissions, external damage caused by power outage accidents have occurred.

1.2.3 planting trees under power lines. Conflict trees line the electricity sector has also been troubled by a headache in recent years, the township government to encourage farmers to grow the development of forestry revenue, without considering the line safe passage, a large line illegal plant trees yearly, due to ground trip power outages caused by trees, affecting the normal order of the power supply when the power distance between power lines and trees more than the required safety distance, high-voltage discharge of trees would be if the rain or the air humidity is too large, under high pressure, the trees will become conductor of the trees surrounding the building, equipment, and underground pipelines are hazardous and may cause significant equipment, personal injury.


2 measures to strengthen the management of transmission line

2.1 improve the technical staff, management staff levels and quality of personnel services is to improve the level of construction management basis to make extensive use of domestic and international construction practice and training opportunities, please come in and go out to take a combination of training, in order to facilitate the class talent.


2.2 strengthen the close cooperation of law enforcement agencies, increase the punishment, the crackdown and punish criminals sabotage, to protect the safety of power facilities.

Protection of power facilities work, especially the government can not do without the great support of government departments, therefore, must establish a sound administrative enforcement mechanism, according to the law against damage, theft, illegal power facilities, according to law for the power industry and the protection of the normal power supply order to play a huge role and performance.

Professional modern project management software, project management to meet the many demands, mainly progress control, but can also be cost control and resource management. Thus, according to the specific circumstances of the project, according to project requirements and objectives of management people, financial, and material inputs, etc., to develop practical and feasible, the application of scientific and rational planning and management methods for the effective use of good project management software, make the construction project management, is also very important.


2.4 Technical measures transmission line insulator correct selection and use, ensure security and stability of insulator, thereby reducing the power and line operation and maintenance. Long rod insulator material can be divided by a long rod composite insulators and porcelain insulators.

Selection of the transmission line insulator suggestions:
(1) hanging string insulator disc should use pollution prevention or long-rod insulators porcelain insulators. Insulators Porcelain China disc manufacturer and more yield, but the quality of products from different manufacturers vary widely. In addition Tension strings can be use an ordinary type, the umbrella should be a choice of two or three umbrellas umbrella, while the bell-type insulators should not use the deep edge.

(2) the mechanical strength of porcelain rod insulators and porcelain pieces directly related, since the transport, damage during installation, or operation outside chance of impact, or the manufacturing process in the formation of internal defects (the strict requirements of product quality inspection, good manufacturing process), may unexpectedly break in operation, so the porcelain rod insulators should choose good quality products, and to strengthen inspection and carefully transport and installation.

(3) blew glass insulator with zero benefits, can save a lot of operation and maintenance costs common type of glass insulator strings can be used in Tension.

(4) composite insulator with less maintenance, quality, small, tolerance and good performance, which is porcelain, glass insulators can not be compared to actively study assessing its performance and life of the technical specifications and test methods for line operation should strengthen the monitoring of composite insulators.


3 Conclusion

Power Engineering construction management is a science, management, continually explore new ideas, explore more advanced and scientific management practices and technology, power engineering enterprises of every common goal. Let us perseverance to learn, explore, learn advanced management techniques, improve business management and technical standards to ensure quality construction, built in a highly competitive electricity market, the company is well positioned to survive and develop.
