This gaseous looped netowrk cabinet that aerifys of fluorine-free environmental protection, including the casing, characterized by: CO is sealed in the shell 2 The upper part of the shell is fixed with a static contact seat, the lower part of the static contact seat is provided with an isolation contact knife, the lower part of the isolation contact knife is connected with a conductor, the lower part of the conductor is connected with an arc extinguish chamber, and the lower end of the arc extinguish chamber is connected with a wire outlet sleeve through a branch bus. The utility model has the advantages that: having the same SF 6 The gas cabinet has the same size and has real isolated ports, and part of components can be matched with SF 6 The gas cabinet is universal and has good matching performance. The whole structure has good reliability, flexible arrangement, small occupied area, high modularization and low production cost, and greatly reduces the emission of greenhouse gases.
Description
(I) technical field
The utility model belongs to the technical field of power switching equipment, in particular to gaseous looped netowrk cabinet that aerifys of fluorine-free environmental protection.
(II) background of the invention
The existing gas ring main unit is not universal, poor in matching performance, poor in reliability of the whole structure, complex in arrangement, large in occupied area, incapable of being produced and assembled in a modularized mode, and high in production cost.
Disclosure of the invention
The utility model discloses a remedy prior art not enough, provide a gaseous looped netowrk cabinet that aerifys of fluorine-free environmental protection that low in production cost, feature of environmental protection are good, the commonality is strong, the reliability is high, area is little.
The invention is realized by the following technical scheme:
the utility model provides a fluoride-free environmental protection gas inflation looped netowrk cabinet, includes the casing, characterized by: CO is sealed in the shell 2 The upper part of the shell is fixed with a static contact seat, the lower part of the static contact seat is provided with an isolation contact knife, the lower part of the isolation contact knife is connected with a conductor, the lower part of the conductor is connected with an arc extinguish chamber, and the lower end of the arc extinguish chamber is connected with a wire outlet sleeve through a branch bus.
The isolation contact knife is installed on the shell through the fixing plate.
And a pressure relief film is arranged at the bottom of the shell.
The lower part of the isolation contact knife is connected with the grounding contact seat.
The utility model has the advantages that: having the same SF 6 The gas cabinet has the same size and has real isolated ports, and part of components can be matched with SF 6 The gas cabinet is universal and has good matching performance. The whole structure has good reliability, flexible arrangement, small occupied area, high modularization and low production cost, and greatly reduces the emission of greenhouse gases.
(IV) description of the drawings
The present invention will be further described with reference to the accompanying drawings.
FIG. 1 is a schematic structural view of the present invention;
in the figure, 1 casing, 2CO 2 The device comprises a gas body, a 3 static contact seat, a 4 isolation contact knife, a 5 conductor, a 6 arc extinguish chamber, a 7 branch bus, an 8 wire outlet sleeve, a 9 fixing plate, a 10 pressure relief film and a 11 grounding contact seat.
(V) detailed description of the preferred embodiments
The attached drawing is a concrete embodiment of the utility model. This embodiment comprises a housing 1, with CO sealed within the housing 1 2 The gas 2, 1 top of casing is fixed with stationary contact 3, and the below of stationary contact 3 is equipped with keeps apart and touches sword 4, keeps apart and touches sword 4 below and connect conductor 5, and the explosion chamber 6 is connected to conductor 5 below, and 6 lower extremes of explosion chamber are connected with wire outgoing sleeve 8 through branch generating line 7. The isolating contact knife 4 is mounted on the housing 1 by a fixing plate 9. The bottom of the shell 1 is provided with a pressure relief film 10. The lower part of the isolation contact knife 4 is connected with the grounding contact seat 11.
Adopt the utility model discloses a gaseous looped netowrk cabinet that aerifys of fluoride-free environmental protection, 1 top of seal housing is fixed with the side extension that both sides pass through the generating line connection, the below is fixed with stationary contact seat 3 and grounding contact seat 11 respectively, it rotates to connect stationary contact seat 3 and conductor 5 to keep apart to touch sword 4, keep apart to touch sword 4 and realize keeping apart the combined floodgate through rotating and stationary contact seat 3 contact, it realizes the ground connection function with grounding contact seat 11 contact to keep apart to touch sword 4, 6 adoption of explosion chamber are vertical to be arranged, but supporting SF such as gas tank and mechanism 6 The gas cabinet structure, the components and parts commonality is higher. The conductor 5 is connected with the arc extinguish chamber 6 in vertical transmission through flexible connection, the outlet insulator is installed at the outlet of the outlet sleeve 8, and the outlet insulator is connected with an external cable, so that sufficient distance is reserved between the live conductors for insulation, and safety is guaranteed. When accidents occur or damage occurs in the ring main unit, a large amount of gas and heat are generated and released from the pressure release film 10, so that the ring main unit is protected, and equipment loss and casualties caused by field personnel are avoided. The rotary knife type isolation grounding switch is adopted, a large fracture can be realized, the air insulation distance is met, the T-shaped cable terminal is connected with a cable, the annular feed-through current transformer is matched, a voltage transformer and a lightning arrester can be additionally arranged, and the line protection and the metering are realized.
