Description
Technical field
This utility model relates to a kind of insulation ring main unit, belongs to electric field.
Background technology
Looped network refers to ring distribution system, i.e. supply main forms the annular of a Guan Bi, power supply electricity
Source powers to this ring main, is outwards joined by high-voltage switch gear from main line another Lu Yilu
Electricity.Such benefit is, each distribution branch road both can with its main line power taking source, left side,
Again can be by main line power taking source on the right side of it.When left side, main line is out of order, and it is just from right side main line
Continue to be powered, and when right side main line is out of order, and it just continues to be supplied from left side main line
Electricity, so, although main power is single service, but for each distribution branch road
But obtain the material benefit being similar to supply power with double circuit, thus improve the reliability of power supply.
At present, electric arc is harm transmission line of electricity and the first big potential safety hazard of maintainer how
Arc extinguishing becomes a big problem of current electrically transportation art, has solid, vacuum and gas to go out at present
Arc, and especially with SF in gas6Being main, it has multiple advantage, and such as, sulfur hexafluoride has well
Electrical insulation properties and the arc extinction performance of excellence, its electric strength is nitrogen under same pressure
2.5 times, breakdown voltage is 2.5 times of air, and arc extinguishing ability is 100 times of air, is one
Plant the supertension insulating dielectric materials of new generation being better than between air and oil.
But, show according to up-to-date research, SF6Gas is greenhouse gases, simultaneously in discharge
After be decomposed into toxic gas, such as SO2, CF4, CO etc., therefore can be to environment and right
Human body will also result in injury.
Summary of the invention
This utility model provides a kind of insulation ring main unit, solves the problems referred to above, uses nontoxic nothing
The noble gas of evil prevents electric arc from endangering, and this ring main unit structure is ingenious, and small volume can be wide
General in community, school and integrated mill.
The technical solution of the utility model: a kind of insulation ring main unit, including cabinet, control unit,
Vacuum arc extinguishing unit, gas transmission room and isolated location；
Described isolated location includes the fixing seat being installed in cabinet, being installed on fixing seat can be certainly
By the rotary shaft rotated, it is connected to rotary shaft the rotating blade that can rotate around rotary shaft, connection
Contact in rotating blade front end, it is connected to the elastic guide rod of leading-out terminal, is located at elastic guide rod
Isolation static contact and the grounding static contact being installed on installing plate of front end；
Described contact can with rotating blade rotate and can rotation stroke in described company
It is connected to isolation static contact that the elastic guide rod front end of leading-out terminal is provided with and is installed on installing plate
Grounding static contact is electrically connected；
Described rotary shaft is connected with described control unit；
Described vacuum arc extinguishing unit includes dielectric moldings, static contact, moving contact, connecting lever and stretches
Guide rod, described static contact one end is electrically connected in described rotating blade, and described moving contact is installed on flexible
Guide rod front end is also electrically connected by soft arranging wire with bus end；
The main shaft of described connecting lever is installed on installing plate and is connected with described control unit, described connecting lever tail
End is connected with described flexible guide rod tail end transmission；
Preferentially, described vacuum arc extinguishing unit housing is to be formed by epoxy resin casting.
Preferentially, described gas transmission indoor gas includes nitrogen and argon.
Preferentially, in described isolated location, it is additionally provided with gas sensor, is used for collecting gas shape
State information.
Beneficial effect: this utility model makes rotating blade contact by control unit transfer motion power
With isolation static contact or grounding static contact be electrically connected be matched with manipulation connecting lever power end push vacuum go out
The moving contact of arc unit guide rod front end disconnects with static contact or Guan Bi realizes connecting, isolating and connect
Ground operation, ensures the security reliability of environment additionally by gas compartment conveying gas.
