The comprehensive maintenance aims to improve the health level of the line and the equipment, prolong the service life of the line and the equipment, eliminate factors which are not beneficial to the safe operation of the line and regularly carry out comprehensive inspection and renovation work on the line.
Attention points in the maintenance process: all the overhaul works must carefully fill in work tickets and operation tickets according to the regulations and firmly execute a work ticket system. Before work, a working responsible person must read work tickets to all constructors (including civil workers) to carry out two-way intersection, the principle of 'one person for maintenance and one person for monitoring' is adhered to in the maintenance process, and after all the maintainers leave a work site and remove a grounding wire, the person can be switched on to supply power.
Maintenance and repair items and periods (I) of power lines and equipment, and pretesting periods and items of 35kv transformers: 1. Measuring the direct current resistance of a winding: the treatment is carried out once in 1-3 years; after the tap of the non-excitation voltage regulating transformer is changed; after the tapping switch of the on-load tap changing transformer is overhauled; after major repair or when necessary. 2. Winding insulation resistance, absorption ratio, or polarization index: the treatment is carried out once in 1-3 years; after major repair or when necessary. 3. Dielectric loss tangent: the treatment is carried out once in 1-3 years; after major repair or when necessary. 4. Winding leakage current: the treatment is carried out once in 1-3 years; after major repair or when necessary. 3. And (3) oil quality test: the treatment is carried out once in 1-3 years; after major repair or when necessary. (seventhly), 35kv main network line maintenance project: 1. cleaning an insulator: the cleaning is carried out for 1 year at regular intervals, and the cleaning is carried out for 1 year twice in a filthy area. 2. Galvanized iron tower fastening bolt: once in 5 years. 3. Fastening bolts of each part of the concrete pole: once in 5 years. 4. Iron tower painting: the treatment is carried out once in 3-5 years, and can be determined according to the situation. 5. And (3) metal base anticorrosion treatment: according to the checking condition.
The grounding wire is a necessary device for grounding power failure equipment in maintenance work and has the function of preventing the working personnel from electric shock and casualty caused by voltage and electric arc generated during sudden power on. In order to ensure the safety of equipment and personnel, the electric power safety work regulation stipulates that a grounding wire needs to be hung when power failure works. However, in practical work, the problems that a key component of the conventional grounding wire is inconvenient to hang and install, easy to fall off, poor in hanging effect and the like are found.
The existing wire clamp clamps the wire only by two clamping leaves, has no locking function and has certain defects in structure. The potential safety hazard of falling off easily occurs under the action of collision, pulling or strong wind. The ground wire loses the protection function, and people are very easy to get an electric shock.
