First, power installation
1. Transformer installation (). The installer should combine the amount of transformer installation work, arrange the construction reasonably, and control the construction and installation points. For large transformers, the installer should make full use of the tools to install the transformer to the specified location. During the unpacking process of the transformer, do not damage the insulation of the transformer. After a thorough inspection of the transformer, confirm every step of the installation process.
2. Cable installation. During the cable installation process, the laying method should be reasonably designed according to the site conditions to ensure the cable installation quality. Common cable laying mainly includes wall installation and wall installation. In order not to affect the power output, it is necessary to avoid improper installation. At the same time, do a good job of moisture prevention, and fundamentally eliminate potential safety hazards.
3. Busbar installation. In the process of installing the busbars and circuit breakers, it is necessary to select the busbars with appropriate specifications in combination with the actual construction conditions. Common busbars include hard busbars, soft busbars, and closed busbars. After the busbar is installed, a strict inspection is required.
4. The isolation switch is installed. Install the isolating switch to control the strength. When the switch gear is in good condition, ensure that the gear is tight and the line can operate normally. During the installation process of the ground knife connecting rod, it is necessary to control the distance between each other and improve the installation quality.
Second, equipment debugging
After the installation of the power is completed, in order to verify the performance of the electrical equipment, it is necessary to ensure the normal operation of the equipment, so it is necessary to carry out the debugging work of the relevant equipment.
First, the insulation resistance and monitoring device should be debugged to ensure the normal operation of the relay protection device. The protection device is then comprehensively commissioned.
Secondly, the debugging of the trip protection device is done well, and the reclosing of the protection device is tested in cooperation with each other to meet the actual line maintenance needs.
