Fig. 1 to Fig. 3 is referred to, the embodiments of the invention provide a kind of SF6One of gas-insulated ring network cabinet collector
Embodiment, including:Elastic Bolts 1, interface agent 2, to connection module 3, connecting rod 4 and gas outlet tube 5;
Interface agent 2 is hollow structure, connection module 3 is arranged in the hollow space of interface agent 2, Elastic Bolts 1 with
The non-hollow partial threads connection of interface agent 2, one end of connecting rod 4 are connected with to the outlet side of connection module 3, connecting rod 4
The other end is connected with gas outlet tube 5, and when promoting Elastic Bolts 1, interface agent 2 is used to move and expose in connecting rod 4
To connection module 3, connection module 3 is used to dock with the air valve 6 of ring main unit when exposing, to offering extruding on connection module 3
Structure 9 and passage 11, extrusion structure 9 are used for the spring leaf for extruding the air valve 6 of ring main unit.
It should be noted that Elastic Bolts 1 are stainless steel, the spring of bolt is fabricated from iron, and mould is docked for controlling
The position of block 3, ensure the tight fit with the original air valve 6 of ring main unit.Interface agent 2 is square shape, and is stainless steel
Material, combined with Elastic Bolts 1, Elastic Bolts 1 are goed deep into inside interface agent 2 by circular hole.It is brass to connection module 3
Material, is used for and SF6The interface of air chamber closely connects, and discharges gas by the spring leaf for extruding ring main unit air outlet valve.Gas goes out
Mouth pipe 5 flows out for gas, typically needs connecting valve and connects collector such as gas production bag etc..
In the present embodiment, the hollow space of interface agent 2 is cylindrical shape.
In the present embodiment, the peaceful Elliptic Cylinder 32 of cylinder 31 is included to connection module 3;
The peaceful Elliptic Cylinder 32 of cylinder 31 is integrally formed, the bottom surface center of circle of cylinder 31 and the bottom surface of flat oval cylinder 32
It is centrally disposed on same straight line.
In the present embodiment, the bottom surface radius of cylinder 31 is less than the short radius in bottom surface of flat oval cylinder 32, flat oval post
The specification of body 32 and the match specifications of the hollow space of interface agent 2.
In the present embodiment, flat oval main body 32 and the hollow space of interface agent 2 form two arch dead slots.
In the present embodiment, the screw rod of Elastic Bolts 1 is provided with recess, and buckle 10, recess are connected with flat oval cylinder
For coordinating snap-lock to expose state to connection module.
In the present embodiment, it is characterised in that include two passages 8 to connection module, extruding is provided with cylinder 31
Structure 9, two passages 11 are symmetrical arranged with extrusion structure 9 for symmetrical centre.
Referring to Fig. 3, SF6The original gas outlet of gas-insulated ring network cabinet connects gas gauge 8 by an air valve 6, its
Middle connection guide 7 is connected on air valve 6, gas is passed through pressure gauge 8 by extruding the spring leaf in air valve 6, so as to show gas
Indoor gas pressure value.
It is set to be separated with air valve 6 rotation of connection guide 7 first, now the spring leaf in air valve restores to the original state, and ensures to set
Standby internal gas may not flow into air.In fig. 2, elastic screw rod 1 is promoted on earth so that interface agent 2 is overall can be with
Move in connecting rod 4, after being moved to low order end, connection module 3 is protruded, matrix buckle is connected with to the outer ledge of connection module 3
10 can fasten with the recess inside elastic screw rod 1, make the state that protrusion is locked in connection module 3.Then will be right to connection module 3
The spring leaf and push-in of quasi- air valve 6, wherein can extrude the spring leaf at the center of air valve 6 to connection module 3 so that the both sides of air valve 6
Gas port can be opened ventilates to two passages 11.Because the air pressure in air chamber is higher than 0.1Mpa, gas can be flowed out by interface.
The specific works step of the present invention is as follows:
(1) equipment that take gas is determined, before taking gas, facilities for observation barometric information, whether pointer is normal, and facilities for observation is transported
Market condition, skin temperature and smell etc., start to take gas in the case where ensuring security situation;
(2) by SF6The panel of gas-insulated ring network cabinet is removed, check air chamber whether gas leakage, and gas outlet valve whether
Normal operation.Ensuring to be dismantled under normal circumstances;
(3) through SF6The air gauge of gas-insulated ring network cabinet air chamber connection and the connection guide connected are removed together, and
Whether normal observe outlet valve;
(3) collector of the installation present invention, by the spring leaf of the docking module alignment air outlet valve in interface agent and leads to
Crossing rotation spring bolt makes spring keep compressive state by square interface agent and SF6The outlet valve of gas-insulated ring network cabinet
Connection, by the Valve controlling outlet speed and gas output that export connection.
(4) after taking depressed beam, spring bolt, which is extracted, makes spring maintain the original state, and square interface is extracted.By former SF6Gas
Body insulation ring main unit air gauge and connecting rod screw in outlet valve, check again for air chamber air-tightness and air gauge whether
Install successfully, ensure that equipment is air tight.
Referring to Fig. 1, in order that prominent state must be kept to connection module during gas is taken, it need to be locked,
Locking process is as follows:
(1) Elastic Bolts 1 are promoted make it that the edge of the screw rod and the hollow space of interface agent 2 of Elastic Bolts 1 is tangent, this
When can be by promoting Elastic Bolts 1 to protrude connection module 3;
(2) after correct position is protruding to connection module 3, rotate to connection module 3 cause its internal edge buckle 10 with
The recess of Elastic Bolts 1 is tangent;
(3) after unclamping Elastic Bolts 1, Elastic Bolts 1 move down under the action of the spring, the recess of Elastic Bolts 1
No longer tangent with the edge of the hollow space of interface agent 2, its edge contacts chimeric, completion with buckle 10 after declining certain distance
Locking.
Described above, the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations;Although with reference to before
Embodiment is stated the present invention is described in detail, it will be understood by those within the art that:It still can be to preceding
