<p>PURPOSE:To improve workability such as installation, exchange and wire bonding of a road-installation type transformer tower by installing a prefabricated transformer containing tower on a transformer installing pit formed on a road and composing to remove the tower at the working time. CONSTITUTION:A transformer containing tower 3 is composed of a frame 1 for fixing a transformer containing pit provided on a road, a branch switch section containing tower 2 having a primary side branch switch section and an openable side plate 2b for operating disconnecting switches and the like contained simultaneously, side plates 3a, 3b, 3c prefabricated at three side surfaces, and an upper plate 3d. After a transformer is installed and a wiring work is completed, the plates 3a, 3b, 3c are associated with the frame 1 in this sequence, one end of the plate 3d is then engaged and enclosed with one upper end of the frame 1, thereby eliminating the removal of the side plates 3a, 3b, 3c, and locking them through a key hole 4. In this manner, the workability such as installation, exchange and wire bonding can be improved.</p> |
