Abstract
A casing inflation flange belongs to a connector in the gas insulation sealed composite apparatus (GIS) field, comprises a flange body and is characterized in that one side of the flange body is directly welded on a casing, and a connection surface is arranged on the other side of the flange body. An inflation through hole is arranged at the center of the connection surface, two connection blind holes with inner threads are symmetrically arranged outside the inflation through hole, and a gas density relay is directly connected onto the inflation flange body through the blind holes. By adopting the scheme, the inflation flange and the gas density relay are in direct butt joint, the gas tubing connection intermediate links are omitted, the number of possible leakage points is reduced, and gas leakage possibility is reduced; and the structure is simplified and cost is reduced.
Description
Technical field:
The utility model relates to a kind of adpting flange on gas insulation metal seal combined electrical apparatus (referred to as GIS) field, particularly combined electrical apparatus gas chamber shell.
Background technology:
Gas insulation metal seal combined electrical apparatus (referred to as GIS) is the good insulating properties of a kind of SF6 of utilization gas and the switching device of arc extinguishing, it mainly partly is made of circuit breaker, isolating switch, earthed switch, voltage transformer, current transformer, lightning arrester, bus, cable end or sleeve pipe etc., each several part uses SF6 gas as dielectric, isolate with air-tightness and the good disc insulator of pitch-durable performance simultaneously, form some air chambers, the rated pressure of SF6 gas is 0.6MPa in the air chamber.GIS monitors the air pressure of each air chamber by gas density relay.
As shown in Figure 3, Figure 4, nipple 2 on the gas chamber shell 1 can't directly be connected with gas density relay 6 at present, gas density relay is fixed on the housing by support, gas density relay 6 needs gas pipe arrangement 5 could monitor the air pressure of air chamber SF6 gas 3 in the housing, might become leakage point 7 in the junction between gas density relay 6 and the gas pipe arrangement 5, between gas pipe arrangement 5 and the nipple 2 like this, strengthen the possibility of Leakage Gas.If also have tie point in the middle of the gas pipe arrangement 5, more can make and to increase by leakage point.
The utility model content:
The problem that exists in order to overcome above-mentioned prior art, the purpose of this utility model have provided a kind of housing inflation flange, and with simplified structure as far as possible, reducing may leakage point.
The technical scheme in the invention for solving the technical problem is:
A kind of housing inflation flange, comprise flange body, it is characterized in that, described flange body one side directly is welded on the housing, opposite side is joint face, central authorities at joint face are provided with the inflation through hole, are provided with two tapped connection blind holes in the external symmetry of inflation through hole, and gas density relay directly is connected on the inflation flange body through described blind hole.
Described blind hole is the M10 screw.
The diameter of inflation through hole is φ 14.
The utility model adopts such scheme, and the inflation flange directly docks with gas density relay, has removed the intermediate link that the gas pipe arrangement connects, and reduces the possibility leakage point, reduces the possibility of Leakage Gas; Simplify the structure, reduced cost.
Description of drawings:
Fig. 1 is the structural representation of the utility model housing inflation flange;
Structural representation when Fig. 2 is the utility model use state;
Fig. 3 is the structural representation of existing housing screw thread gas-charging connection;
The structural representation that Fig. 4 is connected with gas density relay for existing housing screw thread gas-charging connection.
Among the figure, 1, housing; 2, nipple; 3, SF6 gas; 4, support; 5, gas pipe arrangement; 6, gas density relay; 7, leakage point; 8, flange body; 9, blind hole; 10, inflation through hole.
Embodiment:
1～Fig. 2 is further described the utility model below in conjunction with Figure of description:
A kind of housing inflation flange, comprise flange body 8, described flange body 8 one sides directly are welded on the housing 1, opposite side is joint face, central authorities at joint face are provided with axial inflation through hole 10, be provided with two tapped connection blind holes 9 in 10 external symmetrys of inflation through hole, gas density relay 6 directly is connected to by securing member on the inflation flange body 8 through described blind hole 9.Described blind hole is the M10 screw, and the diameter of inflation through hole is φ 14.Flange body 8 arranges two, about each one.
Because the inflation flange directly docks with gas density relay, removed the intermediate link that the gas pipe arrangement connects, reduce the possibility leakage point, reduce the possibility of Leakage Gas; Simplify the structure, reduced cost.
During operation, gas density relay 6 directly is connected with flange body 8 on the housing 1, possible leakage point 7 quantity that produce because of connection are 1, are at least 2 (shown in the figure being 3) and improve the front possible leakage point quantity that produces by the connected mode of gas pipe arrangement 5 and nipple 2.This shows, use inflation flange body 8 can greatly reduce the quantity of possibility leakage point 7, thereby reduce the possibility of Leakage Gas.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
