Abstract

Disclosed is a 220kV power distribution unit outgoing line structure. The 220kV power distribution unit outgoing line structure comprises an outgoing line side isolation switch connected with a power distribution unit, and a voltage transformer and a lightning arrester are both connected to an output line of the outgoing line side isolation switch; and the voltage transformer and the outgoing line side isolation switch are arranged on the same prop. The distance from the outgoing line side isolation switch to an enclosure wall is 7 meters. According to the 220kV power distribution unit outgoing line structure adopting the technical scheme, the voltage transformer is arranged on the prop of the outgoing line isolation switch to form combined equipment; and, in the arrangement manner, the distance from the outgoing line side isolation switch to the enclosure wall is shortened to be 7 meters, and the longitudinal dimension is effectively reduced. The technology has a wide application prospect and can be used in all open type transformer stations; and, if the technology is further popularized, land occupied areas of the transformer stations are further reduced, and the land resource is saved.

Description

220kV power distribution equipment outlet structure
Technical field
The utility model relates to a kind of outlet arrangement of 220kV power distribution equipment.
Background technology
As shown in Figure 1,220kV power distribution equipment adopts open type to arrange, when outlet isolating switch 1, voltage transformer 2 and lightning arrester 3 routines are arranged, equipment room is apart from being followed successively by 4 meters, 3 meters, outlet isolating switch is 9 meters apart from enclosure wall, and this arrangement fore-and-aft distance is larger, has increased floor space.
Summary of the invention
The purpose of this utility model is to provide the 220kV power distribution equipment outlet structure that a kind of floor space is little.
For achieving the above object, the utility model is by the following technical solutions:
A kind of 220kV power distribution equipment outlet structure, it comprises the outgoing line side isolating switch being connected with power distribution equipment, voltage transformer and lightning arrester are all connected on the output line of outgoing line side isolating switch; Described voltage transformer and outgoing line side isolating switch are arranged on same pillar.
Described outgoing line side isolating switch is 7 meters apart from the distance of enclosure wall.
The utility model that adopts technique scheme, is arranged in voltage transformer on the support of outlet isolating switch, composition combination plant, and under this arrangement, outlet isolating switch is 7 meters apart from the Range compress of enclosure wall, has effectively reduced longitudinal size.This technology has a extensive future, and all can adopt in open type transformer station, if further promoted, by further compressing the floor space of transformer station, economizes the land resource.
Brief description of the drawings
Fig. 1 is 220kV power distribution equipment outlet structure figure in prior art.
Fig. 2 is the utility model 220kV power distribution equipment outlet structure figure.
Embodiment
