Abstract

The utility model discloses a solid-sealed type breaker pole insulation seat, and specifically relates to the improvement of a solid-sealed type breaker pole. The insulation seat composed of an insulation base, a sealing cover and screws is added to the lower end of the conventional solid-sealed type breaker pole. The upper end and the lower end of the insulation base are respectively provided with an upper concave bench and an annular concave bench, and the upper concave bench and the annular concave bench are communicated via a through hole. Screw holes are evenly arranged in the annular concave bench, and the upper concave bench is matched with the profile of the lower end of the solid-sealed pole. The insulation seat is added to the lower end of the conventional solid-sealed type breaker pole, so that the conventional solid-sealed type breaker pole can be used not only in low altitude regions but also in high altitude regions, a special mould does not need to be prepared for a high altitude type solid-sealed breaker pole, the conventional solid-sealed type breaker pole can be generally used, and therefore a problem that the solid-sealed type breaker pole is ground-insulated when used in the high altitude regions is solved.

Description

Fixed sealing type circuit breaker polar insulating base
Technical field
The utility model relates to a kind of fixed sealing type circuit breaker polar insulating base, is specially the improvement to fixed sealing type circuit breaker polar.
Background technology
In middle pressure vacuum circuit-breaker field, fixed sealing type circuit breaker is owing to having good insulating properties and reliability, be widely applied, the dielectric strength of fixed sealing type circuit breaker depends on pole, the pole of existing product is plain edition, its fracture insulation margin is larger, applicable to 3000 meters and regional above, but insulation against ground distance is generally only applicable to 2000 meters and regional below, if in the time of need to being used in 2000 meters and above high altitude localities, just need the high altitude type pole of special facture mould again, will make product cost increase.
Summary of the invention
The utility model provides a kind of fixed sealing type circuit breaker polar insulating base, is intended to solve the problem of above-mentioned existence.
The utility model is that the technical scheme by below addresses the above problem:
A circuit breaker polar insulating base, sets up an insulating base consisting of insulating base (1), sealing shroud (2) and screw (3) in plain edition fixed sealing type circuit breaker polar lower end.
Described insulating base (1) upper and lower end is respectively equipped with heavy stand (4) and annular heavy stand (6), upper heavy stand (4) is communicated with by through hole (5) with annular heavy stand (6), annular heavy stand (6) is provided with equally distributed screw (7), and upper heavy stand (4) matches with pole lower end profile.
Inward flange (9) and the outward flange (8) of described sealing shroud (2) are loop configuration, outward flange (8) is provided with the installing hole (11) corresponding with the set screw of annular heavy stand (6) (7), and the transition portion that connects outer edge adopts the annular corrugated shape (10) centered by inside and outside edge.
Adopt after above-mentioned fixed sealing type circuit breaker polar insulating base, do not need high altitude type fixed sealing type circuit breaker polar special facture mould again, just can increase plain edition fixed sealing type pole insulation against ground distance, thereby the dielectric strength that improves pole, makes plain edition pole and high altitude type pole form general.
Accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of insulating base.
Fig. 3 is the vertical view of Fig. 2.
Fig. 4 is the structural representation of sealing shroud.
Fig. 5 is the vertical view of Fig. 4.
Fig. 6 is the application example of the utility model insulating base.
Each sequence number explanation in figure: 1. insulating base; 2. sealing shroud; 3. screw; 4. go up heavy stand; 5. through hole; 6. annular heavy stand; 7. screw; 8. outward flange; 9. inward flange; 10. annular corrugated; 11. installing holes; 12. poles.
Embodiment:
Referring to Fig. 1 to Fig. 6, plain edition fixed sealing type circuit breaker polar lower end arranges an insulating base 1, is specifically configured to: insulating base, sealing shroud, screw form.
Insulating base upper and lower side is respectively equipped with heavy stand 4 and annular heavy stand 6, upper heavy stand and annular heavy stand are communicated with by through hole 5, annular heavy stand 6 is provided with equally distributed screw 7, upper heavy stand 4 matches with pole 12 lower end profiles, the inside and outside edge of sealing shroud 2 is loop configuration, and outward flange 8 is provided with the installing hole 11 corresponding with the set screw of annular heavy stand, the transition portion that connects inside and outside edge has annular corrugated 10 shapes centered by outer edge.
Adopt said structure, when fixed sealing type circuit breaker is used for high altitude localities, only need to set up this insulating base in plain edition fixed sealing type circuit breaker polar lower end, just can increase its insulation against ground distance, thereby improve the dielectric strength of fixed sealing type circuit breaker polar, make plain edition fixed sealing type circuit breaker polar both applicable to low altitude area, again applicable to high altitude localities, be that high altitude type fixed sealing type circuit breaker polar does not need special facture mould again, make plain edition fixed sealing type circuit breaker polar form general, solve fixed sealing type circuit breaker polar in high altitude localities insulation against ground problem.
