Greatly (or ground connection thing) or other have the conductor insulation of potential difference.And the utility model is in SF6 gas-insulated transformers
Make interior insulation and support is connected, be subjected to very big mechanical stress and overvoltage, be the core component of SF6 transformers.
Utility model content
The utility model embodiment technical problem to be solved is, there is provided a kind of many passages of the stronger band of reliability
Transformer disc insulator.
The transformer disc insulator with many passages, including peviform insulation pouring body, the peviform it is exhausted
Edge pour mass middle part is in be provided with multigroup passage, the insulation pouring body top of the peviform and bottom at the curved flex point of " s " type
Surface is provided with the attachment means for being connected with external equipment, and the attachment means include that the insulation for being arranged on the peviform is poured
Injection body top and lower surface shrinkage pool and the inserts being arranged in the shrinkage pool, inserts top and middle part be provided with for
The fastener of the shrinkage pool inwall engaging, the inserts middle part is provided with cavity, and screw thread is provided with the cavity inner wall, described embedding
Glass grid cloth is provided between part and the shrinkage pool.
The insulation pouring body middle part of the peviform is separately positioned in four groups of passages are provided with the curved flex point of " s " type
At the curved flex point of " s " type at circular quadrant position.
The tangent line of the passage central axis flex point curved with " s " type is vertical, and the passage is to the insulation
Sub- big opening direction upwarps.
The logical section of ventilation is ellipse.
The insulation pouring body top of the peviform and bottom are circumferentially arranged at intervals with 8 attachment means.
Implement the utility model embodiment, have the advantages that:
A kind of transformer disc insulator with many passages of the utility model embodiment, lateral pull is 30000N/
5min, failure test pulling force is more than 90000N, and inserts periphery bag glass grid has enough adhesions, in SF6 gases, when
Air pressure be 0.35MPa when, after pre-add power frequency test voltage 460kV/60s, under test voltage 252kV partial discharge quantity≤
10pC, partial discharge quantity answers≤2pC under test voltage 174kV.After particularly adding 4 passages, by disc insulator
Gas passage area increased more than one times, and quickly transmission and gas are mutually dredged to be easy to pressure, on accident build-up of pressure is unexpected
When rising, reduce destructive power and make pressure releaser quick acting, improve the operational reliability of transformer.

Connection device.
A kind of transformer disc insulator with many passages of the utility model embodiment, lateral pull is 30000N/
5min, failure test pulling force is more than 90000N, and inserts periphery bag glass grid has enough adhesions, in SF6 gases, when
Air pressure be 0.35MPa when, after pre-add power frequency test voltage 460kV/60s, under test voltage 252kV partial discharge quantity≤
10pC, partial discharge quantity answers≤2pC under test voltage 174kV.After particularly adding 4 passages, by disc insulator
Gas passage area increased more than one times, and quickly transmission and gas are mutually dredged to be easy to pressure, on accident build-up of pressure is unexpected
When rising, reduce destructive power and make pressure releaser quick acting, improve the operational reliability of transformer.
Above disclosed is only a kind of preferred embodiment of the utility model, can not limit this practicality with this certainly
New interest field, therefore the equivalent variations made according to the utility model claim, still belong to what the utility model was covered
Scope.
