The present invention relates to a molded transformer provided with a fire extinguishing device. According to the present invention, a lower frame (14) is positioned on a base (10), and an upper frame (20) is supported by the lower frame (14) and provided at the upper part of the lower frame (14). The lower frame (14) and the upper frame (20) are connected by a tie rod (28), and a steel core (30) is supported by the lower frame (14), the upper frame (20) and the tie rod (28). Secondary coils (38) are provided to surround the steel core (30), and primary coils (34) are provided to allow the secondary coils (38) to penetrate the inside thereof. A case (50) is provided at one end part of the lower frame (14), and fluid containers (52) are provided in an area partitioned by the case (50). A section of a pipe (54) connected with the fluid containers (52) extends along the upper frame (20). A nozzle (56) is provided at the pipe (54) for spraying fluid between the primary coil (34) and the secondary coil (38) or between the outer surfaces of the primary coils (34). According to the present invention, since a fire-extinguishing fluid is directly sprayed at the primary coils (34) and the secondary coils (38) at which a fire can occur, a fire-extinguishing operation can be performed more rapidly. |
