Abstract
The utility model provides a connecting flange for gas insulated switchgears. The connecting flange is characterized in that: the connecting flange comprises a flange, three first sleeves which are used for matching with a conductive bus and a disconnector are arranged on one end of the flange, three second sleeves which are used for matching with the poles of a circuit breaker are arranged on the other end of the flange, and the upper first sleeves correspond to the lower second sleeves. The connecting flange for gas insulated switchgears, which is disclosed by the utility model, is mainly applied in the connection between the three-position switch bus and the circuit breaker, i.e. the connection between an upper gas chamber and a lower gas chamber. The connecting flange for gas insulated switchgears integrates the three-phase sleeves in the prior art together, so that the structure is simpler, and meanwhile, a bus compartment can be effectively sealed as well; the connecting flange disclosed by the utility model also increases the creepage distance, and ensures that solid insulation is parallel to a bus, so that the distribution of an electric field is more uniform.
Description
Technical field
The utility model belongs to the switch cubicle fitting field, is specifically related to a kind of adpting flange of gas-insulated switchgear.
Background technology
The three-station bus of gas-insulated switchgear and being connected of circuit breaker in the prior art, the single-phase sleeve pipe of most employings is connected with plug-in unit, perhaps adopts case mode altogether.Single-phase sleeve pipe and plug-in unit connected mode have increased leak source, and its structure is comparatively complicated; Need the bus power failure during the feasible maintenance complicacy of case mode, and maintenance altogether, use inconvenience.
The utility model content
The utility model provides a kind of adpting flange simple in structure to the deficiency of above-mentioned prior art.
The utility model is realized through following technical scheme:
A kind of adpting flange of gas-insulated switchgear; It is characterized in that; Comprise a ring flange; One end of said ring flange is provided with three and is used for first sleeve pipe that is complementary with busbar and isolating switch, and the other end of ring flange is provided with three and is used for second sleeve pipe that is complementary with circuit breaker polar, and first sleeve pipe is corresponding up and down with the position of second sleeve pipe.
The further setting of the utility model is that said ring flange along the circumferential direction is provided with the sealing rubber ring mounting groove.
The further setting of the utility model is that the outer periphery of said ring flange is equipped with the epoxy resins insulation layer.
The further setting of the utility model is that the edge of said ring flange is provided with the construction bolt hole.
The adpting flange of the described gas-insulated switchgear of the utility model is mainly used in being connected of three-station bus and circuit breaker, promptly goes up the connection of lower chamber.The adpting flange of this gas-insulated switchgear is integrated three-phase sleeve pipe of the prior art as a whole, and its structure is simpler, can realize good sealing to bus-bar room again simultaneously; The described adpting flange of the utility model has also strengthened along the face creep distance, and makes solid insulation parallel with bus, makes Electric Field Distribution more even.
Description of drawings
Fig. 1 is the front view of the said adpting flange of the utility model;
Fig. 2 is the vertical view of the said adpting flange of the utility model;
Fig. 3 is the partial sectional view of the said adpting flange of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Shown in Fig. 1-3; The utility model provides a kind of adpting flange of gas-insulated switchgear; Comprise ring flange 1; One end of said ring flange 1 is provided with three and is used for first sleeve pipe 2 that is complementary with busbar and isolating switch, and it is corresponding up and down with the position of second sleeve pipe 3 that the other end of ring flange 1 is provided with three second sleeve pipe, 3, the first sleeve pipes 2 that are used for being complementary with circuit breaker polar.In order to guarantee the airtight and insulation of air chamber, said ring flange 1 along the circumferential direction is provided with sealing rubber ring mounting groove 4, and the outer periphery of ring flange 1 is equipped with epoxy resins insulation layer 5.For the ease of installing, the edge of said ring flange 1 is provided with construction bolt hole 6.
The above is the preferred embodiment of the utility model, and all equivalent variations of being done according to the utility model claim all should belong to the protection range of the utility model.
