technical field

The utility model relates to the technical field of substations, in particular to a frame for incoming and outgoing lines of a 330kV power distribution device.

Background technique

With the improvement of my country's overall economic strength and the voltage level of substations, more and more steel structures are used in the selection of materials for the structure of substation power distribution devices. Especially in the AC and DC projects of 220kV and above, steel frames are all used.

At present, the 330kV power distribution device structure of the substation using HGIS equipment adopts the intermediate structure. The conventional HGIS equipment is to arrange the busbar bushing on both sides of the equipment according to the position of the tubular busbar, and arrange the outlet bushing in the middle position. Lift the outgoing line to the upper transition to realize the lead-out of the outgoing line. As shown in Figure 1, the electrical safety clearance between the two side phases near the middle of the conventional layout needs to meet

Considering the impact of the string length of 330kV tension insulators installed on the intermediate frame on the position of the down-conductor, the electrical safety net distance between the side phases near the middle of the two busbars is set to 17m.

In order to solve these problems, it is necessary to adopt certain technical means to cancel the intermediate frame, which can effectively save the area occupied by the 330kV power distribution device and reduce the amount of steel used for the frame of the 330kV power distribution device. Under the premise of increasingly tightening land policies and the promotion of energy conservation and environmental protection, it is the future development trend of electric power construction to cancel the intermediate structure, save land occupation and save steel consumption.
