Abstract
The utility model provides a miniature GIS equipment which adapts to the main domestic connection practice and is at a voltage level of 252kV,aiming at the disadvantages of large size, more switching units and inconvenient on-spot examination and repair. The equipment comprises at least two phases of switch devices. And each phase switch device comprises two multi-phase shared switch devices, an inlet/outlet line unit, and a gas-insulated packaging unit comprising a circuit breaker unit, two CTs and three combined switches. The equipment is characterized in that: the circuit breaker unit is horizontally arranged and the two sides of the breaker are respectively connected with the bus-side CT and the line-side CT; two vertically-installed bus-side combined switch are symmetrically arranged to connect the main bus bar; a horizontally-installed line-side combined switch is arranged on the upper end of the line-side CT to connect with the inlet-outlet unit.
Description
Technical field
The utility model relates to a kind of Cubicle Gas-Insulated Switchgear (GIS) of 252kV electric pressure.
Background technology:
Miniaturization and high reliability are the technical advantages of GIS, also are the main developing direction of GIS always.
The GIS technical scheme of existing 252kV electric pressure is divided into two big classes generally.One class is to be the 252kVGIS of representative with domestic conventional solution, and volume is bigger, and interval width adopts the isolation and the earthed switch unit of two stations more than 2 meters, and amount of parts is many, and site examining and repairing is inconvenience comparatively.Also having a class is to be the 252kVGIS of representative with the external technical scheme that occurs recently, though interval width is little, element number is few, but because the difference of home and abroad station main electrical scheme pattern, external scheme is when adopting domestic common circuit breaker both sides to add CT (current transformer) scheme, interval height all surpasses 3.6 meters, can't realize the prepackage of integrated spaced factory, then by the mode of supplly of common this modern switchgear of goods stock whole Transporting.
Summary of the invention
The utility model provides a kind of miniaturization GIS equipment that adapts to the 252kV electric pressure of domestic main electrical scheme custom at the defective that existing 252kVGIS volume is big, switch element quantity is many, site examining and repairing is inconvenient.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of Cubicle Gas-Insulated Switchgear, constitute by two-phase switching device at least, each phase switching device comprises two heterogeneous shared main bus bar tubes, a turnover line unit, and the unit of following gas-insulated encapsulation a: breaker unit, two CT and three unit switches, it is characterized in that, described breaker unit horizontal arrangement, its both sides are connection bus side CT and line side CT respectively, and described bus bar side CT upper end is symmetrical arranged two bus bar side unit switches of vertically installing and connects the main bus bar tube; Described line side CT upper end is provided with the unit switch connection turnover line unit, line side that a level is installed.
In the such scheme, described bus bar side and line side unit switch are angle type three station isolation earthing switch; Described line side unit switch connects turnover line unit by an earthed switch; This earthed switch also can be contained in the unit switch of described line side.
The utility model adopts the horizontal layout of breaker unit, and circuit breaker bus side is provided with two unit switch unit of vertical installation, and an identical unit switch unit has been adopted in the line side, thereby has realized the switch element minimum number; The shared main bus bar tube of three-phase places bus bar side unit switch top, is convenient to the independent maintenance and the replacing of main bus bar tube.Outlet side unit switch unit is connected with turnover line unit by the earthed switch with making capability, and the circuit breaker both sides add CT and highly are no more than 3.3 meters, can realize whole transportation at interval.Compare with existing like product, it is little to the utlity model has volume, and compact conformation is convenient to transportation, safe and reliable characteristics.In power plant construction, can reduce floor space, reduce project cost, non-maintaining or few maintenance.The city transformer station, transformer station of enterprise, mountain area transformer station and the filthy serious area that are specially adapted to the land used anxiety are used.
