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 the 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:
The outdoor high-voltage alternating current combined electrical apparatus is a present electric power system electric equipment commonly used.At present, the employed high pressure combined electrical apparatus of electrical network mainly is made up of bushing, three merit position isolating switches, earthed switch, current transformer, circuit breaker both at home and abroad.Electric pressure is based on the above equipment of 72.5kv.
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, a kind of compact combined high-voltage switchgear has appearred in the world.This equipment complex the advantage of open type and enclosed switch equipment.It is integrated with the high voltage device height, and it is compact more to make it high voltage switchgear.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.The existing at present application example that transformer is docked with the pipe bus of GIS.But also have no talent transformer and HGIS are combined.
Summary of the invention:
The objective of the invention is in the above electric pressure electrical network of 40.5kV, together transformer and circuit breaker, isolating switch, earthed switch, current transformer, sleeve combination.It is transformer and HGIS combination.But this combination is not a kind of simple connection, must thresh 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: the 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 be the high pressure combined electrical apparatus of unit with the transformer.Can be called THGIS, ask the city as a kind of high pressure combined electrical apparatus of new construction.

Embodiment:
Structure of the present invention is based on transformer, and according to the size of transformer, adopt 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 among the present invention relates to docking of lead-out wire and HGIS.Connector is the main devices of butt joint, the primary structure of connector is as shown in Figure 4: 7 oil gas sleeve pipes, 8 housings, 9 bellowss, 11 contacts, 12 fingertip of relying on oneself wherein, its outside is made up of oil gas sleeve pipe 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 sleeve pipe 7 constitutes.Required oil gas sleeve pipe, it is with insulating oil in the transformer and the reliable main element of isolating of the insulating gas among the HGIS, the oil gas sleeve pipe its objective is the different stress that absorb two equipment rooms with housing and bellows butt joint.Fill insulating gas in the connector.To guarantee the dielectric strength of electrified body and shell.Earlier connector is docked with HGIS during installation, the contact of will relying on oneself is fixed on oil gas sleeve pipe termination, inserts contact together with the oil gas sleeve pipe.The HGIS that slings inserts in the rising seat of transformer, and the footing of HGIS drops on the cross member of transformer and be good with bolt simultaneously.Open the hand hole of the seat that raises, once going between of transformer is fixed on the binding post of oil gas sleeve pipe.Make the seat Nei Chong Full insulating oil that raises behind the sealing hand hole.The oil gas casing flange is connected with shell and bellows shell, and the fingertip of relying on oneself that oil gas inside pipe casing termination is fixing inserts contact, between contact and circuit breaker disc insulator is arranged, disc insulator termination fixed contact.Disc insulator is that an independent air chamber fills insulating gas to guarantee interior insulation to the oil gas sleeve pipe.The connection of equipment such as circuit breaker and isolating switch is identical with conventional HGIS.
1, the HGIS High-Voltage Electrical Appliances of various countries' production at present are independently converting equipment.Be combined in the home and abroad also beyond example with transformer group.
2, the external and internal compositions of connector is gone back beyond example in putting into practice at home, outward.
3, rated voltage: 40.5kV above electric pressure is as 72.5kV, 126kV, 252kV.
4, rated frequency: 50Hz
5, transformer capacity can be decided according to user's needs
6, adapted operating mechanism: circuit breaker is joined spring mechanism, tri-station isolating switch distribution actuation mechanism.
7, current transformer is according to customer requirements; But luminous intensity distribution electricity instrument transformer or electromagnetic transformer.
