Lead-in wire switch sections integral body is fixed in oil tank transport base.
In described carrying case, be also provided with the support angle steel and the steel plate that increase transportation intensity.
The transportation resources of a kind of transformer lead switch sections that disintegrates of the present invention, is characterized in that comprising the following steps:
During design, disintegration transformer lead is adopted to live connect, be divided into switch sections lead-in wire and device body and partly go between;
Before transportation, device body is partly gone between to live in connecting to be disconnected, and neutral lead-in wire disconnects with switch place cable and copper rod, and the switch sections that makes to go between is independent of device body;
Upper switches support and switch and switch place lead-in wire are not removed, and integral body is fixed in oil tank transport base, jointly transports with upper oil tank.
The switch bracket of lead-in wire switch sections and switch and switch place lead-in wire integral body are fixed on the adapter plate of oil tank transport base, prevent that in transportation, lead-in wire rocks damage lead-in wire.
Extension supporting angle steel in upper oil tank transport base, to increase wire clamp support intensity.
The present invention has following beneficial effect and advantage:
1. the present invention is in to go between to be connected to design with switch place lead-in wire at device and survives connection, when convenient machine body disintegrates, disconnects and going between, and has shortened field installation time, has accelerated progress.
2. the present invention makes switch place lead-in wire together transport with upper oil tank, has saved traffic cost.

The specific embodiment
Below in conjunction with Figure of description, the present invention is further elaborated.
The present embodiment is with outdoor field assembled, three-phase self coupling, No-load changer, forced oil-circulation air-cooled (ODAF), copper coil transformer, model is that the voltage transformer of ODFPS-JT-1000000/500 is example, user is located in 1600m plateau, hill path is rugged, bridge bearing only has 60t, only has the disintegrating transportation could be by the so large transformer transporting of capacity to erecting stage.For accelerating on-the-spot installation work progress, lead-in wire switch sections integral transportation, to on-the-spot rear integral installation.
The transport structure of a kind of transformer lead switch sections that disintegrates of the present invention is that after voltage transformer is disintegrated, lead-in wire switch sections is fixed in oil tank transport base, together transports with upper oil tank.Lead-in wire adopts to live and connects, and is divided into switch sections lead-in wire and device body and partly goes between; Copper rod in the high-side lead that wherein device body partly goes between is lived in connecting and is disconnected (as shown in Figure 1), and low pressure side neutral cable, middle pressure copper rod disconnect (as shown in Figure 2), and tap changer side is independent of device body; Switch bracket and switch and switch sections lead-in wire integral body are fixed in oil tank transport base; In upper oil tank, be also provided with the support angle steel and the support bracket fastened adapter plate (as shown in Figure 5) that increase wire clamp support intensity.
During voltage transformer disintegrating transportation, the disconnection (as shown in Figure 3) that partly goes between of lead-in wire switch sections and device body, the same oil tank transports together, partly goes between and is connected again after transporting to scene with device body.
The invention process process is as follows:
1. high-side lead transportation is processed
A, B, the copper rod in C tri-phase terminals and the tap changer place copper rod of lead-in wire switch sections disconnect.In order conveniently to realize transport structure of the present invention, when design disintegration transformer lead, down-lead device body part is connected and adopts alive connection with lead-in wire switch sections, while facilitating voltage transformer to disintegrate, disconnects lead-in wire.
2. the transportation of low pressure side lead-in wire is processed
Middle pressure and neutral lead-in wire disconnect with switch place cable and copper rod.
3. switch bracket and switch and switch place lead-in wire are not removed, with upper oil tank integral transportation.
During the transportation of lead-in wire switch sections, the cable being connected with three single-phase switch contacts does not disconnect with contact, with switch place support integral transportation.Switch bracket transports jointly with lead-in wire switch sections and upper oil tank, and switch bracket bottom is fixing with upper oil tank bottom, during transportation, provides transportation with angle steel 1 and the steel plate 2(that increases transportation intensity as shown in Figure 4 A).As shown in Figure 5, after lead-in wire switch sections lifting, fall in the transport base of oil tank, fixing by adapter plate 3, while preventing from transporting, move and impaired.
During on-the-spot installation, lead-in wire switch sections utilizes switch bracket integral lifting (as shown in Figure 4 B), falls within on the switch bracket that is fixed on lower clamping piece, and partly go between pressure regulation copper rod and middle pressure, neutral copper rod cable of device body is connected.
