Abstract
The utility model relates to a sulfur hexafluoride circuit breaker, which comprises an A-phase porcelain knob, a B-phase porcelain knob, a C-phase porcelain knob, a frame, a supporting frame and an operating mechanism arranged at the lower end in the middle of the frame. The sulfur hexafluoride circuit breaker is characterized in that an arc extinguishing chamber is arranged inside each porcelain knob, a pull rod is arranged at the lower portion of the arc extinguishing chamber, an axial gas sealing device arranged at the connecting position of the arc extinguishing chamber with the frame includes scratch-resistant parts, shaft seals, a sealing part, a fixed part I and a fixed part II, the fixed part I is arranged on the periphery of the pull rod, a plurality of the scratch-resistant parts and a plurality of the shaft seals are arranged between the fixed part I and the pull rod, the fixed part II is fixed onto the periphery of the fixed part I, and a plurality of the sealing parts are arranged between the fixed part II and the fixed part I. The sulfur hexafluoride circuit breaker has the advantages of fine sealing effect, high reliability and simple and convenient assembly.
Description
Technical field
The utility model relates to high pressure and ehv power transmission switchgear, relates in particular to a kind of sulfur hexafluoride breaker.
Background technology
Sulfur hexafluoride breaker is used widely at high pressure and ehv power transmission system break road device, but the leakage that how to prevent gas particularly the gas anti-leak work of axial motion place fail effectively to be solved always.
The utility model content
The purpose of this utility model provides a kind of sulfur hexafluoride breaker, can effectively solve the technical problem that existing circuit breaker axial seal effect does not add.
The technical solution adopted in the utility model is:
Sulfur hexafluoride breaker, comprise A, B, the porcelain knob of C three-phase, framework, bracing frame and the operating mechanism of being located at the frame mid portion lower end, be provided with arc control device in the described porcelain knob, described arc control device bottom is provided with pull bar, described arc control device and framework junction are provided with the axial gas sealing device, described axial gas sealing device comprises anti-scratch parts, the axle envelope, seal, fixing device I and fixing device I I, be provided with fixing device I around the described pull bar, be provided with a plurality of anti-scratch parts and a plurality of envelopes between described fixing device I and pull bar, be fixed with fixing device I I around the described fixing device I, be provided with a plurality of seals between described fixing device I I and the fixing device I.
Described anti-scratch parts are wear ring, and described seal is the O RunddichtringO.
The utility model is positioned by the direction of motion of wear ring to pull bar, because the arc control device internal gas pressure is greater than atmospheric pressure, force axle envelope compressive deformation to form the axially airtight of pull bar like this, utilize the effect of fixing device I and fixing device I I mutual extrusion and seal to form airtight between fixture, thereby realize the airtight of total system.
The advantage of utility model is: good sealing effect, reliability height, simple and convenient assembly.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the end view of Fig. 1.
Fig. 3 is the cutaway view of axial gas-tight sealing among Fig. 2.
Wherein: 1, wear ring, 2, axle envelope, 3, pull bar, 4, seal, 5, fixing device I, 6, fixing device I I, 7, framework, 8, bracing frame, 9, operating mechanism, 10, porcelain knob, 11, arc control device, 12, the axial gas sealing device.
Embodiment
As Figure 1-3, sulfur hexafluoride breaker of the present utility model, comprise A, B, the porcelain knob 10 of C three-phase, framework 7, bracing frame 8 and the operating mechanism 9 of being located at lower end, framework 7 middle part, be provided with arc control device 11 in the porcelain knob 10, arc control device 11 bottoms are provided with pull bar 3, arc control device 11 are provided with axial gas sealing device 12 with framework 7 junctions, axial gas sealing device 12 comprises anti-scratch parts, axle envelope 2, seal 4, fixing device I 5 and fixing device I I6, these anti-scratch parts are wear ring 1, be provided with fixing device I 5 around the pull bar 3,3 on fixing device I 5 and pull bar are provided with a plurality of wear rings 1 and a plurality of envelopes 2, be fixed with fixing device I I6 around the fixing device I 5, be provided with a plurality of seals 4 between fixing device I I6 and the fixing device I 5, these seals 4 are the O RunddichtringO.
The utility model is positioned by the direction of motion of 1 pair of pull bar 3 of wear ring, because arc control device 11 internal gas pressures are greater than atmospheric pressure, force axle envelope 2 compressive deformations to form the axially airtight of pull bar 3 like this, utilize the effect of fixing device I 5 and fixing device I I6 mutual extrusion and seal 4 to form airtight between fixture, thereby realize the airtight of total system.
The advantage of utility model is: good sealing effect, reliability height, simple and convenient assembly.
