Description
Technical field
The invention belongs to Ultra-high Voltage Substations design and construction technical field, particularly the arrangement of 500kV HGIS power distribution equipment in a kind of Ultra-high Voltage Substations.
Background technology
500kV transformer station is the load-center substation of electric power system, plays very important effect to regional economic life.Affect by the factor such as environment, economic index, in China 500kV transformer substation power distribution unit, more and more have employed composite and gas-insulated unit switch equipment (HGIS).
Composite and gas-insulated unit switch equipment (HGIS), that (hanging tubular bus is lifted by pipe bus insulator string by the bus employing open type hanging tubular bus in 500kV power distribution equipment, be suspended on bus gate framework, it is a kind of form of bus bars between the soft bus and support type busbar line of strain insulator, general use aluminium-alloy pipe bus, there is anti-seismic performance good, bus sag, windage yaw is waved and the advantage little to framework pulling force, be used for the 220KV power distribution equipment of superhigh voltage distribution equipment and earthquake prone areas), and by circuit breaker (GCB), isolating switch (DS), earthed switch (ES), the primary equipments such as high speed grounding switch (FES) and current transformer (CT) are closed in metal shell, and in fill SF6 gas-insulated composition.Bus grounding switch, lightning arrester and voltage transformer can be built in HGIS equipment, also can external employing opening-type equipment.It absorbs the too high negative issue that brings of GIS integrated level and the problem such as AIS monolithic element combination floor space is excessive, have simple and compact for structure, floor space is little, operational reliability is high, maintenance workload is little, easy for installation, and foundation of civil work amount is few, short construction period, without advantages such as oil ring guarantors.
500kV HGIS power distribution equipment adopts 3/2 mode of connection, i.e. 3 circuit breaker series connection between 2 buses, form a complete string.In a complete string, draw transmission line circuit between adjacent 2 circuit breakers, namely 3 circuit breakers are for two transmission line circuits, and middle circuit breaker, as sharing, is equivalent to each transmission line circuit 1.5 circuit breakers, therefore also referred to as bus scheme with one and half breaker.In a complete string of 3/2 wiring, 2 circuit breakers being connected to bus are referred to as limit circuit breaker, and middle circuit breaker is referred to as middle circuit breaker.
In 500kV HGIS power distribution equipment, along several intervals of bus horizontally set, arrange complete string (also namely complete be serially connected with between two groups of buses) in an interval, with the circuit breaker of three in complete string for arrangement unit, arrangement mainly contains three kinds:
A) " 1+1+1 " mode
In HGIS power distribution equipment, 3 circuit breakers are independent all separately, connect and compose a complete string to each other by flexible conductor.
B) " 2+1 " mode
In HGIS power distribution equipment, 2 circuit breakers are linked to be an entirety, and another 1 circuit breaker is independent, and centre connects and composes a complete string by flexible conductor.
C) " 3+0 " mode
In HGIS power distribution equipment, 3 circuit breakers are linked to be an entirety and form a complete string.
Above-mentioned 3 kinds of conventional 500kV HGIS arrangements are at interval of interior configuration complete string, and the quantity at interval is by main wiring mode and the very difficult minimizing of control of joining string mode, therefore above-mentioned 3 kinds of arrangement floor spaces are larger, and interval quantity causes framework consumption steel material large more, and then the cost of investment making transformer station total is higher, reorganization and expansion construction inconvenience, economic and social benefits are poor.
