Abstract
The utility model discloses an oil gas bushing connection gas pipe apparatus for a 220 combination electric appliance, including an oil gas bushing cross (1); the horizontal direction of the oil gas bushing cross (1) is in connection with an interval equipment branch bus (2) through a gas cutting insulator (7); the lower part of the oil gas bushing cross (1) is in connection with an oil gas bushing branch bus (3); the casing side part of the oil gas bushing cross (1) is in connection with a stop valve I (4) through a bolt; the stop valve I (4) is in connection with a stop valve II (6) through an oil gas bushing connection pipe (5); the stop valve II (6) is in connection with the interval equipment branch bus (2) through a bolt. The oil gas bushing connection gas pipe apparatus reduce the use of SF6 gas and a density relay and reduces cost; on-site operation is convenient, the time of on-site gas recovery and inflation is saved and on-site workload is minimized.
Description
Technical field
The utility model relates to a kind of 220kV combined electrical apparatus oil-gas casing and connects tracheae device.
Background technology
When 220kV combined electrical apparatus main transformer interval is connected by oil-gas casing with main transformer of transformer substation, oil-gas casing need to be set up independent air chamber.Onsite acceptance is withstand voltage to four-way place to combined electrical apparatus: (1) is if horizontal direction branch bar is same air chamber in four-way below branch bar and interval, because oil-gas casing does not need withstand voltage, need extract isolation fracture conductor and make oil-gas casing and interval equipment form isolation fracture, can slattern all SF in oil-gas casing and in the equipment level direction branch bar of interval
6gas; (2) save if gas oil-gas casing four-way below branch bar and interval equipment level direction branch bar are divided into two independent air chambers by gas cutting insulator, need two density monitors, increased the extra cost of 1 density monitor.
Summary of the invention
The utility model, for above weak point, provides a kind of 220kV combined electrical apparatus oil-gas casing to connect tracheae device, has saved SF
6the use of gas and density monitor, has saved cost, and execute-in-place is convenient, has saved the time that gas on-site reclaims and inflates, and has reduced work on the spot amount.
The utility model solves the technical scheme that its technical problem adopts: a kind of 220kV combined electrical apparatus oil-gas casing connects tracheae device, include oil-gas casing four-way, described oil-gas casing four-way horizontal direction connects interval equipment branch bar by gas cutting insulator, described oil-gas casing four-way bottom connects oil-gas casing branch bar, described oil-gas casing four-way housing sidepiece is bolted break valve I, described break valve I connects break valve II by oil-gas casing tube connector, and described break valve II is bolted interval equipment branch bar.
On described oil-gas casing tube connector, be provided with elastic bend part.
The beneficial effects of the utility model are:
Between oil-gas casing four-way and interval equipment branch bar, be provided with oil-gas casing tube connector, and be provided with break valve thereon, realize connected sum between oil-gas casing four-way and two air chambers of interval equipment branch bar and independently freely switched, when withstand voltage, saved SF
6gas, has reduced the use of density monitor, thereby has saved cost; Execute-in-place is convenient, has saved the time that gas on-site reclaims and inflates, and has reduced work on the spot amount.
Brief description of the drawings
It shown in Fig. 1, is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown be a specific embodiment of the present utility model, a kind of 220kV combined electrical apparatus connects tracheae device with oil-gas casing, include oil-gas casing four-way 1, described oil-gas casing four-way 1 horizontal direction connects interval equipment branch bar 2 by gas cutting insulator 7, described oil-gas casing four-way 1 bottom connects oil-gas casing branch bar 3, described oil-gas casing four-way 1 housing sidepiece is bolted break valve I4, described break valve I4 connects break valve II6 by oil-gas casing tube connector 5, and described break valve II6 is bolted interval equipment branch bar 2.
On described oil-gas casing tube connector 5, be provided with elastic bend part.
When scene is withstand voltage, extract the isolation fracture conductor of oil-gas casing four-way 1 inside, close two break valves, oil-gas casing four-way 1 air chamber and interval no longer UNICOM of equipment branch bar 2 air chambers, be divided into two air chambers, horizontal direction interval equipment branch bar 2 gas indoor gas, without bleeding off, only need discharge the SF in oil-gas casing four-way 1 air chamber
6gas.
After withstand voltage completing, in oil-gas casing four-way 1 air chamber, be inflated to equipment rated pressure, turn on both sides break valve, oil-gas casing four-way 1 and interval equipment branch bar 22 air chambers UNICOMs merge into same air chamber, share 1 density monitor.
Than two kinds of traditional processing modes, the application of this tracheae device has larger economic implications for combined electrical apparatus manufacturer, has saved SF
6the cost of gas and density monitor, and execute-in-place is convenient, has saved the time that gas on-site reclaims and inflates, and has reduced work on the spot amount.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art make in essential scope of the present utility model, also should belong to protection range of the present utility model.
Claims (2)
1. a 220kV combined electrical apparatus connects tracheae device with oil-gas casing, include oil-gas casing four-way (1), described oil-gas casing four-way (1) horizontal direction connects interval equipment branch bar (2) by gas cutting insulator (7), described oil-gas casing four-way (1) bottom connects oil-gas casing branch bar (3), it is characterized in that, described oil-gas casing four-way (1) housing sidepiece is bolted break valve I(4), described break valve I(4) connect break valve II(6 by oil-gas casing tube connector (5)), described break valve II(6) be bolted interval equipment branch bar (2).
