Abstract
A mixed type power distribution equipment loop for 220kV GIS and opening-type equipment, comprises power distribution equipment loop bus, and described power distribution equipment loop bus adopts GIS device, and other equipment of power distribution equipment loop adopts opening-type equipment.Other equipment of described power distribution equipment loop comprise circuit breaker, outlet isolating switch, current transformer, voltage transformer and lightning arrester.Save floor occupying area than opening-type equipment, simplify the mixed type power distribution equipment loop of wiring, in conjunction with the advantage of GIS device and opening-type equipment, cost ratio GIS device is cheap simultaneously.
Description
Technical field
The utility model belongs to field, 220kV power distribution equipment loop in 220kV transformer station, is specifically related to the mixed type power distribution equipment loop of a kind of 220kV GIS and opening-type equipment.
Background technology
In 220kV transformer station, 220kV power distribution equipment circuit units all adopts GIS device or opening-type equipment design.
GIS device and totally-enclosed SF6 gas insulated combined electrical equipment, main elements such as bus, circuit breaker, isolating switch, current transformer, voltage transformer, lightning arresters, combined closing (only outlet casing tube or cable termination is naked is exposed on the external) in the metal shell of ground connection, fills the switchgear assembly formed as dielectric using the SF6 gas of certain pressure.The outstanding advantage of GIS be reliability high, arrange clear, save take up an area, maintenance workload is little, environmental suitability is strong, but expensive comparatively speaking.At present, GIS is widely used in power grid construction.
Opening-type equipment, refers to that in power distribution equipment loop, all devices is separately independently, adopts the conductive medium such as steel reinforced aluminium conductor to connect and compose the power distribution equipment pattern of complete loops between specific installation.Loop comprises the conventional equipments such as supported tube type bus, porcelain knob/potting breaker, isolating switch, current transformer, voltage transformer, lightning arrester, forms medium-sized power distribution equipment outside room.This design major advantage is that equipment manufacturing cost is low, and weak point is that number of devices is many, and wiring is complicated, and floor space is large, and operating maintenance workload is large.
Utility model content
In order to solve the problem, the utility model provides the mixed type power distribution equipment loop of a kind of 220kV GIS and opening-type equipment.Save floor occupying area than opening-type equipment, simplify the mixed type power distribution equipment loop of wiring, in conjunction with the advantage of GIS device and opening-type equipment, cost ratio GIS device is cheap simultaneously.
For achieving the above object, the utility model is by the following technical solutions:
The mixed type power distribution equipment loop of a kind of 220kV GIS and opening-type equipment, comprise power distribution equipment loop bus, described power distribution equipment loop bus adopts GIS device, and other equipment of power distribution equipment loop adopts opening-type equipment, and described GIS device only comprises bus and bus isolating switch.
Other equipment of described power distribution equipment loop comprise circuit breaker, outlet isolating switch, current transformer, voltage transformer and lightning arrester.
Complete loops is connected and composed by conductive medium between each equipment in described power distribution equipment loop.
Described conductive medium is steel reinforced aluminium conductor.
Adopt the utility model of technique scheme, there are following 2 advantages: 1) bus adopts GIS pattern, and floor space can reduce 81% compared with the supported tube type bus in opening-type equipment; 2) mixed type power distribution equipment loop capital equipment still adopts opening-type equipment, cheap, and only bus adopts GIS device pattern, and price is high compared with the supported tube type bus of open type.Overall power distribution equipment loop is cheap, between opening-type equipment and GIS device price.

Fig. 1 is opening-type equipment structure section schematic diagram.
Fig. 2 is structure section schematic diagram of the present utility model.
Fig. 3 is opening-type equipment structural plan schematic diagram.
Fig. 4 is structural plan of the present utility model schematic diagram.
Embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the mixed type power distribution equipment loop of a kind of 220kV GIS and opening-type equipment, comprise power distribution equipment loop bus, described power distribution equipment loop bus adopts GIS device, other equipment of power distribution equipment loop adopts opening-type equipment, and described GIS device only comprises bus 2 and bus isolating switch 3.Other equipment of described power distribution equipment loop comprise circuit breaker 1, outlet isolating switch, current transformer, voltage transformer and lightning arrester.Complete loops is connected and composed by conductive medium between each equipment in described loop.Described conductive medium is steel reinforced aluminium conductor.
The interval width of the supported tube type bus in traditional opening-type equipment is 13000mm, bus longitudinal size floor space is 18500mm, the interval width of the GIS bus that the utility model adopts is 13000mm, the same with traditional open equipment, but bus longitudinal size floor space is 3500mm, obviously little than the floor space of traditional opening-type equipment.
