Abstract
The utility model relates to a welding fixture of an axial sectional superhigh voltage shielding case of electric test equipment, which can guarantee the combination precision. The shielding case comprises a semi-circular left body and a semi-circular right body which have a C-shaped cross section respectively. A screw hole for connecting with the superhigh voltage test equipment is arranged in the middle of the inner surface of the shielding case. The welding fixture comprises a base arranged horizontally, a central upright pole perpendicular to the base and at least one pair of adjustable screws arranged horizontally. The adjustable screws comprises a rod one which is fixedly connected to the central upright pole, a rod two which is detachably connected with the screw hole at the inner surface of the shielding case and a screw barrel with rightwise and leftwise threads, wherein the rod one is coaxially connected with the rod two through the screw barrel with the rightwise and leftwise threads. When welding process is needed, the two semi-circular bodies of the superhigh voltage shielding case are combined on the base, thereby obtaining the superhigh voltage shielding case corresponding to designing requirements for dimensional precision.
Description
Technical field
The utility model relates to the weld jig that axially cuts fraction super-pressure radome in the power test equipment.
Background technology
When the power equipment charging test,, need radome be set in correlation test instrument, device external for preventing the influence of high voltage electric field to test apparatus, equipment.The power test equipment of different structure shape needs the adaptive radome of profile with it, such as, be applied in the transformer of the annular in the super-pressure test, its outside radome one is the requirement that needs to adapt to the super-pressure occasion, the 2nd, and its structure can be suitable with transformer.The super-pressure radome is the vitals of voltage transformer in the high-voltage fence, and the super-pressure radome is different from general radome, and the industrial frequency withstand voltage that it bears requires than higher, and manufacturing process is relatively stricter, and particularly the radome curved surface requires to be lower than the 5pc discharge capacity.
At present, the ring shielding cover that is applied in the transformer outside all is global formation usually, and the radome body is circular, the c-shaped shape in cross section, and opening is in the inner ring inboard.But the Mold Making more complicated of global formation, demoulding inconvenience, production efficiency is low, the production cost height.For this reason, the applicant provides the super-pressure radome of a kind of fraction on the basis of satisfying the prior art products performance, and it has the pair of semicircular shaped semi-ring, and involutory formation is aforementioned circular.But during welding processing, can not guarantee that it is consistent to the distance at center, cause installing hole and shielding periphery disalignment, off-centre when causing the client to install impacts shield effectiveness.During therefore involutory welding, need guarantee welding precision.
The utility model content
The utility model provides a kind of when an axial section fraction super-pressure radome is carried out welding processing at above problem, can guarantee the weld jig that axially cuts fraction super-pressure radome of involutory precision.
The technical solution of the utility model is: described radome comprise a pair ofly be semi-annular shape, the cross section is a left side half body and right half body of C shape, described radome inner surface middle part is provided with the screw that is used to connect the super-pressure testing equipment; Described weld jig comprises horizontally disposed base, perpendicular to central upright stanchion and horizontally disposed at least one pair of adjusting screw of base; Described adjusting screw comprises the bar two and the positive and negative tooth swivel nut of screw on the bar one that is fixedly connected on the central upright stanchion, the described radome inner surface that removably connects, and described positive and negative tooth swivel nut is with described bar one and two coaxial linking to each other of bar.
Described adjusting screw is provided with two pairs.
Have location reference block or the type groove consistent on the described base with described radome Lower Half outer profile size.
When needing welding processing, be placed on the base of the present utility model a pair of super-pressure radome hemizonid is involutory, base has location reference block or the type groove consistent with radome finished product Lower Half outer profile size, a pair of hemizonid is inserted between the reference block of location or after within the type groove, the gap can be occurred between the two; By the adjusting screw in the utility model a pair of hemizonid is strutted, then uniform slit can occur between a pair of hemizonid, a pair of hemizonid is fixed on the base by adjusting screw simultaneously; This moment, welding can make the super-pressure radome that dimensional accuracy adheres to specification.

The specific embodiment
The utility model as shown in Figure 1, 2, described radome comprise a pair ofly be semi-annular shape, the cross section is a left side half body 21 and right half body 22 of C shape, described radome inner surface middle part is provided with the screw 23 that is used to connect the super-pressure testing equipment; Described weld jig comprises horizontally disposed base 1, perpendicular to central upright stanchion 12 and horizontally disposed at least one pair of adjusting screw 13 of base 1; Described adjusting screw 13 comprises the bar two and the positive and negative tooth swivel nut 14 of screw 23 on the bar one that is fixedly connected on the central upright stanchion 12, the described radome inner surface that removably connects, and described positive and negative tooth swivel nut 14 is with described bar one and two coaxial linking to each other of bar.
Described adjusting screw 13 is provided with two pairs.
Have location reference block or the type groove consistent on the described base 1 with described radome Lower Half outer profile size.For individual hemizonid (left half body 21 or right half body 22) two location reference blocks (location reference block 1, location reference block 2 112) should be set at least; Or the type groove of the exterior contour consistent size that requires with finished product.Hemizonid must be slightly less than semi-circular when making, to guarantee between the reference block of location, to leave weld seam 3 in the type groove.
