As one of the important components in the power grid, the installation quality of power transformers directly affects their safe and good operation. The installation process of transformers is quite complex and important. Therefore, problems and defects encountered during installation should be promptly addressed to avoid potential hazards.
① Installation methods for power transformers. Installation requires specialized processes and transportation equipment, as well as devices and instruments, and is completed by professional construction personnel following certain procedures. The workload and procedures of transformer installation should be determined based on the structural characteristics of the transformer. Modern transformers are generally designed to be non-disassemblable, then placed in the oil tank and transported to the construction site. However, for large transformers, rigging must be used at the construction site;超低频高压发生器是combined with modern digital frequency conversion advanced technology, using microcomputer control, voltage boosting, voltage reduction, measurement, and protection are fully automated, and manual intervention can be performed during the automatic voltage boosting process. In addition, the workload and procedures of power transformer installation also depend on the structural characteristics of some main equipment of the transformer, such as on-load tap changers, high-voltage bushings, cooling systems, and transformer oil protection devices. Furthermore, before construction, attention should be paid to: determining the placement method and location of the power transformer; ensuring the integrity of insulation when unpacking the transformer; preparing all necessary equipment, tools, and materials required for construction and installation; selecting the technical methods for unloading and moving to the installation construction site; determining the installation procedures and commissioning content of the transformer; planning the construction period and workload, the number of installation personnel, etc.
② Specific installation steps. Install the oil conservator, cooler, and other necessary accessories; when vacuum oil filling, ensure that residual oil is completely drained and vacuum oil filling is guaranteed; when humidity is too low, only one hole cover can be opened to prevent inward air circulation; sometimes it is necessary to seal the tank and apply vacuum, and open the hole cover when appropriate to continue working.
