Abstract

A novel inflation ring main unit disclosed by the present invention comprises an air box, the box body of the air box is formed by welding an inner-layer stainless steel plate and an outer-layer stainless steel plate, and the part between inner-layer stainless steel plate and the outer-layer stainless steel plate is hollow. The thicknesses of the inner-layer stainless steel plate and the outer-layer stainless steel plate are both not less than 3 mm, and the box body is divided by a side plate into a left box body and a right box body. An incoming line insulator is arranged at the upper end of the left side of the left box body, and the lower end of the incoming line insulator extends in the left box body and is connected with a three-position switch. The three-position switch is connected with a vacuum circuit breaker under the three-position switch, and the vacuum circuit breaker is arranged on an insulating support. A connecting busbar is arranged under the insulating support, and the right side of the connecting busbar is connected with an outgoing line insulator. The novel inflation ring main unit of the present invention is more scientific and reasonable, safer and more practical, is especially suitable for protecting a power distribution device of which the voltage is more than 10 KV, and is better in insulating property and protection property.

Description

A kind of aerated ring main unit
Technical field
The present invention relates to a kind of ring main unit, particularly relate to a kind of aerated ring main unit, belong to controller switching equipment skill Art field.
Background technology
No matter distribution technique field is civilian or commercial power is required for carrying out power distribution equipment perfect close Close and protect, to prevent the bionical of something event.The many employings of existing ring network cabinet body are wooden or other metals Material, wooden the firmest, protection against the tide and security performance are poor, and service life is short;Though metal material is firm anti- Tide is effective, but cost is high, and easily gets rusty;Security performance is the most poor.These existing two kinds of ring main units are simply Simply possess the function of protection, performance is single, protection effect is poor and be unsuitable for to voltage 10KV with On controller switching equipment carry out protecting (safety and insulating properties that the controller switching equipment of more than 10KV requires are higher).
Summary of the invention
In order to solve the weak point existing for above-mentioned technology, the invention provides a kind of aerated looped network Cabinet.
In order to solve above technical problem, the technical solution used in the present invention is: a kind of aerated looped network Cabinet, including gas tank, the casing of gas tank is welded by internal layer stainless-steel sheet and outer layer stainless-steel sheet, interior Hollow between layer stainless-steel sheet and outer layer stainless-steel sheet, internal layer stainless-steel sheet and outer layer stainless-steel sheet Thickness be all not less than 3mm;Casing is divided into left box body and right case two parts by side plate;The left side of left box body Upper end is provided with inlet wire insulator, and the lower end of inlet wire insulator is deep in left box body and and three-station phase Connect;Three-station is connected on the vacuum circuit breaker that is positioned under;Vacuum circuit breaker is arranged on insulation On support.
Insulating support is provided below connection busbar;The right side connecting busbar connects outlet insulator.
It is respectively arranged with a power distribution equipment with three-station, insulating support corresponding section in right case;Join Electric installation be provided above with an air gauge.The outside of right case be disposed with from the top down instrument door, Middle door and lower panel;A door lock it is provided with in the middle of the left side of instrument door.
Present invention design is more scientific and reasonable, is particularly suited for carrying out voltage at the controller switching equipment of more than 10KV Protection, insulating properties, protective are more preferable, more safe and practical.
Accompanying drawing explanation
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings.
Fig. 1 is the internal structure schematic diagram of the present invention.
Fig. 2 is the external structure schematic diagram of right part in Fig. 1.

Detailed description of the invention
As shown in Figure 1 and Figure 2, the present invention includes gas tank 6, and the casing of gas tank 6 is by internal layer stainless-steel sheet and outer Layer stainless-steel sheet is welded, and hollow between internal layer stainless-steel sheet and outer layer stainless-steel sheet, internal layer is not The thickness of rust steel steel plate and outer layer stainless-steel sheet is all not less than 3mm.Casing by side plate 15 be divided into left box body and Right case two parts.
The upper end, left side of left box body is provided with inlet wire insulator 5, and the lower end of inlet wire insulator 5 is deep into left box body In and be connected with three-station 7.Three-station 7 is connected to the vacuum circuit breaker 8 being positioned under On.Vacuum circuit breaker 8 is arranged on insulating support 9.Being provided below of insulating support 9 connects busbar 10. The right side connecting busbar 10 connects outlet insulator 4.With three-station 7, insulating support 9 phase in right case Corresponding position is respectively arranged with a power distribution equipment 2.Power distribution equipment 2 be provided above with an air gauge 1.
The outside of right case is disposed with instrument door 12, middle door 14 and lower panel 16 from the top down.Instrument door A door lock 13 it is provided with in the middle of the left side of 12.
Corrosion resistant plate, thickness must not be less than 3mm, and degree of protection should reach IP67, looped network cabinet degree of protection Reach IP4X.
The welding of casing can use Laser Welding or argon arc welding, the weld seam to welding shell, should enter by following provisions Row nondestructive flaw detection examination.The weld seam of key position weld seam and bi-material welding should all be detected a flaw, its It should visit fusion length no less than the 20% of its butt weld total length.Casing requires high-seal.SF6 gas Leakage rate per year is less than for 0.5%/year, and the expectsted of working life of sealing system must not be less than 30 years.Use three stations Switch, work and earthing position reciprocal interlocking, it is possible to sleeve belt electric locking earthing is set, it is ensured that maintenance mans Make safe and reliable;Reciprocal interlocking between vacuum circuit breaker and three-station, in breaker closing state, three Position switch cannot manual and electric deciliter operation.
Above-mentioned embodiment is not limitation of the present invention, and the present invention is also not limited to the example above, this Change that those skilled in the art are made in the range of technical scheme, retrofit, add or Replace, also belong to protection scope of the present invention.
