Abstract
The invention relates to an outdoor high-voltage AC totally-enclosed composite apparatus which is capable of considerably reducing areas of occupied land and decreasing investments in infrastructure. The composite apparatus consists of a transformer, a connector and an HGIS, wherein, a circuit breaker is in horizontal butt joint with the transformer, or the circuit breaker is in vertical butt joint with the transformer; the mounting barrel of the transformer is in butt joint with the connector, the other end of the connector is in butt joint with the circuit breaker, and the connector forms an independent air chamber between the transformer and the HGIS. The composite apparatus is applicable to a power grid. The transformer is used as a unit for the high-voltage composite apparatus. The composite apparatus can be called as THGIS and can be marketed as a high-voltage composite apparatus with a new structure.
Description
Technical field:
The present invention relates to high voltage electrical apparatus technical field, exactly it is combination-outdoor high-voltage alternating current fully closed combined electric unit of a kind of outdoor high-voltage alternating current fully closed combined electric unit and transformer.
Background technology:
Outdoor high-voltage alternating current combined electrical apparatus is the conventional electric equipment of current electric power system.At present, the high-voltage combined electrical apparatus that electrical network is used both at home and abroad, is mainly comprised of bushing, three merit position isolating switches, earthed switch, current transformer, circuit breaker.Electric pressure be take the above equipment of 72.5kv as main.
The Cubicle Gas-Insulated Switchgear that electric power system is used is that Threephase common-box is GIS.(badly damaged other two-phase of a phase fault is unfavorable for the enlarging construction of electric substation.) later stage nineties 20th century, there is in the world a kind of compact combination formula high voltage switchgear.This equipment complex the advantage of open type and enclosed switchgear.It is integrated by high voltage device height, makes it high voltage switchgear compacter.It is HGIS that three-phase is combined respectively.(phase fault does not damage other two-phase, is convenient to the enlarging construction of electric substation.) be more suitable for the use of electrical network and the development of electrical network.The technological progress that HGIS promotes combined electrical apparatus reaches a new stage.Have at present the application example that transformer is docked with the pipe bus of GIS.But also nobody combines transformer and HGIS.
Summary of the invention:
The object of the invention is in 40.5kV above electrical network, by transformer together with circuit breaker, isolating switch, earthed switch, current transformer, sleeve combination.Be transformer and HGIS combination.But this combination is not a kind of simple connection, must repeatedly does multiple design and test just passable.Concrete technical scheme is as follows: it is by transformer, connector, HGIS forms, and it is characterized in that: circuit breaker level is docked with transformer or circuit breaker is vertical docks with transformer, utilize the rising seat of transformer to dock with connector, the connector other end docks with circuit breaker.Connector forms an independent air chamber between transformer and HGIS.
The invention has the beneficial effects as follows: be more suitable for the development need of the above electrical network of 40.5Kv, significantly reduce floor space, reduce the investment of capital construction.It is to take the high-voltage combined electrical apparatus that transformer is unit.Can be called THGIS, as a kind of high-voltage combined electrical apparatus of new construction, ask city.

Embodiment:
Structure of the present invention be take transformer as main body, according to the size of transformer, adopts two kinds of compound modes: a kind of circuit breaker is that horizontal mode docks with transformer.A kind of circuit breaker is that vertical mode is docked with transformer.
Transformer in the present invention relates to docking of lead-out wire and HGIS.Connector is the main devices of docking, the primary structure of connector is as shown in Figure 4: 7 oil-gas casings, 8 housings, 9 bellowss, 11 contacts, 12 fingertip of relying on oneself wherein, its outside is comprised of oil-gas casing 7, connector shell 8, bellows 9, disc insulator 10, and inside is that the gas end by contact 11, the fingertip 12 of relying on oneself, oil-gas casing 7 forms.Required oil-gas casing, it is by the main element of the reliable isolation of the insulating gas in the insulating oil in transformer and HGIS, oil-gas casing its objective is from housing and bellows docking the different stress that absorb two equipment rooms.In connector, fill insulating gas.To guarantee the dielectric strength of electrified body and shell.During installation, first connector is docked with HGIS, the contact of relying on oneself is fixed on oil-gas casing termination, together with oil-gas casing, inserts contact.The HGIS that slings inserts in the rising seat of transformer, and the footing of HGIS drops on the cross member of transformer and fixes with bolt simultaneously.Open the hand hole of the seat that raises, the once lead-in wire of transformer is fixed on the binding post of oil-gas casing.Seat Nei Chong Full insulating oil makes to raise after sealing hand hole.Oil-gas casing flange is connected with shell and bellows shell, and the fingertip of relying on oneself that oil-gas casing internal heads is fixing inserts contact, has disc insulator, disc insulator termination fixed contact between contact and circuit breaker.Disc insulator is that an independent air chamber fills insulating gas to guarantee interior insulation to oil-gas casing.The connection of the equipment such as circuit breaker and isolating switch is identical with conventional HGIS.
1, the HGIS High-Voltage Electrical Appliances that various countries produce at present, are independently converting equipment.Be combined in home and abroad also beyond example with transformer group.
2, the external and internal compositions of connector at home, beyond example also in outer practice.
3, rated voltage: 40.5kV above is as 72.5kV, 126kV, 252kV.
4, rated frequency: 50Hz
5, transformer capacity can need to determine according to user
6, adapted operating mechanism: circuit breaker is joined spring mechanism, tri-station isolating switch distribution actuation mechanism.
7, current transformer is according to user's requirement; Can join photo-electricity mutual-inductor or electromagnetic transformer.
