Abstract: A power transmission tower comprises a tower body (100) longitudinally arranged and cross arms (120) transversely arranged on the tower body. The tower body (100) is provided with a first transverse direction (Y) and a second transverse direction (X), which are perpendicular to each other, in the horizontal direction. A supporting piece (110), which extends outwards from the tower body (100) in the first transverse direction (Y), is arranged on the power transmission tower. One end of the supporting piece (110) is fixed to the tower body (100) and the other end of the supporting piece (110) is a free end (111, 112). The cross arms (120) extend in the second transverse direction (X). One end of each cross arm (120) is connected to the free end (111, 112) and the other end of each cross arm (120) is used for arranging overhead wires. The power transmission tower reduces corridor width and occupies less area.

Under the condition that a breaker and isolation switches meet needs of transformer substation devices, the isolation switches are properly arranged at two sides of an arc extinguish chamber of the breaker in the axial direction. When the breaker achieves it functions, the breaker moves in a reciprocating manner in the axial direction, while when the isolation switches achieve their functions, the isolation switches move in a rotating manner around the axis of the breaker. During the movement process of the isolation switches, the arc extinguish chamber unit of the breaker is in a static state, does not move in a reciprocating manner in the axial direction and does not move in a rotating manner around the axis. The movement system of the breaker and the movement system of the isolation switches are two independent movement systems without mutual interference. According to the combined electric appliance, the breaker and the isolation switches are arranged in the same axis by means of two independent driving systems, the isolation switches are arranged at two sides of the breaker in the axial direction, and the breaker and the isolation switches are highly integrated. The composite combined electric appliance has a simple structure and high applicability, occupies small space, is easy to implement and has reliable performance, and therefore the product structure is further optimized.
