Description
Technical field
This utility model relates to on-load switch technical field, is specifically related to the equal laminated structure of a kind of pressure-operated load switch.
Background technology
The existing pressure-operated load switch being applied to high-tension switch gear is usually free of the measure of special uniform electric field, and under elevated pressure conditions between electric conductor and the electric field strength distribution between casing is existed by electric conductor and uneven field intensity exists, thus broken change dielectric strength.And traditional approach mainly meets insulating properties by the way of increasing electric clearance and creep distance.But, there is hidden danger, and such structural volume be big, does not meets the design concept of closed gas switchgear miniaturization in the most fundamentally Insulation Problems.
Summary of the invention
The purpose of this utility model is to overcome drawbacks described above, a kind of novel structure, compact, electric fields uniform, the equal laminated structure of the reliable a kind of pressure-operated load switch of insulation are provided, this equal laminated structure can improve between on-load switch electric conductor and the electric conductor field strength distribution state to casing, reinforced insulation performance.
For achieving the above object, this utility model is by the following technical solutions:
A kind of equal laminated structure of pressure-operated load switch, including static contact, fixed contact pedestal, arc-extinguish chamber, load switch contact box and support, it is embedded with equal gland inside described static contact and forms the equal gland static contact of band, it is provided with striking pin in described band equal gland static contact, striking pin one end is connected with fixed contact pedestal, equal for band gland static contact upper end is fixed on fixed contact pedestal by striking pin, equal gland static contact lower end is carried to be fixed on arc-extinguish chamber upper end, it is provided with grading shield at the periphery correspondence band equal gland static contact of described arc-extinguish chamber upper end, periphery, arc-extinguish chamber lower end is provided with the first grading ring, described arc-extinguish chamber lower end is connected with load switch contact box, described load switch contact box is fixed on support.
Described equal laminated structure also includes that the second grading ring, described second grading ring are fixed on the outside opposite sides of load switch contact box by support.
Described second grading ring is more than 2.
Further, described striking pin one end is threaded connection with fixed contact pedestal.
Described grading shield and the first grading ring are and are sheathed on arc-extinguish chamber periphery.
This utility model uses above technical scheme, it is embedded with equal gland inside static contact and forms the equal gland static contact of band, it is provided with grading shield at periphery, arc-extinguish chamber upper end correspondence band equal gland static contact, periphery, arc-extinguish chamber lower end is provided with the first grading ring, second grading ring is fixed on the outside opposite sides of load switch contact box by support, use above structure, the leading body components all of pressure-operated load switch has special all pressures measure to reach the purpose of uniform electric field, thus reduces switch fault rate in During Process of Long-term Operation.Arc-chutes inside is all pressed in galvanization by described band equal gland static contact by internal equal gland, grading shield can improve between the electric conductor of arc-extinguish chamber upper end and the Electric Field Distribution of electric conductor and casing, first grading ring can improve on-load switch point, close between process electric conductor and the Electric Field Distribution of electric conductor and casing, the second grading ring can improve between load switch contact box lower conductive body and the Electric Field Distribution of electric conductor and casing.
This utility model compared with prior art has the advantage that existing on-load switch, typically no special uniform field intensity measure, structure is bigger than normal, space availability ratio is low, insulating reliability is low, and the equal laminated structure of pressure-operated load switch of the present utility model, novel structure, compact, electric fields uniform, insulation are reliable, this utility model is while reducing on-load switch volume, add insulating reliability, can effectively improve on-load switch running Electric Field Distribution under 40.5kV electric pressure, thus reinforced insulation effect.
