CN203184877U - Interior supporting welding tool for connecting mouth of shielding case - Google Patents

Abstract

The utility model provides an interior supporting welding tool for a connecting mouth of a shielding case. The shielding case is barrel-shaped. The interior supporting welding tool comprises a wedging support and a pair of symmetric arch-shaped supports, the wedging support and the pair of arch-shaped supports are connected end to end to form a regular circular ring shape fitting the inner edge of a barrel opening of the shielding case, the wedging support is the 1/6-1/8 arc-shaped section of the regular circular ring shape, a first slope facing the interior of the regular circular ring shape is arranged at the two ends of the wedging support, and the arc-shaped supports are provided with second slopes which face the wedging support and fit the first slope. Because the interior supporting welding tool is sleeved in the shielding case and plays a role in supporting, the shielding case can be effectively prevented from deforming. Therefore, shielding precision of the shielding case is guaranteed.

Description

The interior support welding tooling of radome connection

Technical field

The utility model relates to the radome that a kind of high-tension testing apparatus is used, and relates in particular to a kind of device that can effectively control the shielding case structure precision.

Background technology

HT testing transformer is users' such as power plant, power supply administration and R﹠D institution the fundamental test equipment that is used for doing AC voltage withstand test, passed through the standard of State Quality Supervision Bureau, for the dielectric(al) test of various electric products, electric elements, insulating materials etc. being carried out under the assigned voltage, the dielectric level of examination product, find the insulation defect of test specimen, weigh superpotential ability.Its critical piece comprises for pressing testing transformer: ⑴ device body: comprise iron core, winding, insulating element and lead-in wire.⑵ regulator: i.e. shunting switch is divided into non-excitation pressure adjustment and on-load voltage regulation ⑶ fuel tank and cooling device.⑷ protective device: comprise oil conservater, pressure-relief vent, dehydrating breather, gas relay, oil purifier and temperature measuring equipment etc.⑸ insulating sleeve.Bushing shell for transformer is the outer main seal of transformer tank, and the lead-out wire of Transformer Winding must pass insulating sleeve, makes to reach between lead-out wire and the transformer case between the lead-out wire to insulate, and plays fixedly lead-out wire simultaneously.Because of the electric pressure difference, insulating sleeve has forms such as true procelain sleeve pipe, oil filled bushing and capacitance graded bushing.The true procelain sleeve pipe is used for 10kV and following transformer more, and it is to wear a conductive copper bar in porcelain bushing shell, is air insulation in the insulator.Oil filled bushing is used in 35kV level transformer more, and it is oil-filled at porcelain bushing shell, wears a conductive copper bar in porcelain bushing shell, copper bar outsourcing insulating paper.Condenser-type terminal is by major insulation---capacitor core, and external insulation---go up lower ceramic part, branch sleeve, conservator, the spring assembling, base, voltage equalizing ball, measurement terminal, binding post, rubber washer, the insulation wet goods is formed.It is used for the above high voltage transformer of 100kV.Wherein for the insulating properties of guarantee test equipment, need put porcelain bushing shell in the outside of iron core and winding, put radome again in the outside of porcelain bushing shell.To be shield be surrounded the interference source of device body and whole system in the effect of radome, prevents that interfere with electromagnetic field is to external diffusion; With shield entire equipment or system are surrounded simultaneously, prevent that they are subjected to the influence of external electromagnetic field.Small and exquisite for the structure that guarantees high-tension testing apparatus itself, we will control the radome size when design, for radome, design feature is as follows: as shown in Figure 1, its sleeve diameter is big, and wall is thin, simultaneously its design accuracy is required high, so just very high requirement has been proposed for processing technology and project organization, require it in process, keep the circular arc degree of radome not produce deformation, but because the wall of radome own is thin, be easy to generate deformation, cause radome deformation.

The utility model content

This case technical problem to be solved: a kind of interior support welding tooling of radome connection is provided, it be for prevent radome use and process in deformation takes place, thereby the problem of influence shielding precision appears.

Technical scheme:

The interior support welding tooling of radome connection, described radome are tubular, have a horn mouth, establish some connections in described horn mouth inboard, the described interior sole bar reinforcement that welding tooling comprises wedging support and a pair of symmetry that supports,

Constitute a positive annular adaptive with described radome nozzle inner edge behind the sole bar reinforcement headtotail of described wedging support and a pair of symmetry, described wedging support is the segmental arc of described positive annular 1/6-1/18;

The inclined-plane one in described positive annular ring is offered at the two ends of described wedging support, and described sole bar reinforcement is provided with the inclined-plane two suitable with described inclined-plane one towards the end face of described wedging support.

Technique effect:

Owing to support welding tooling in radome, being with, play a supporting role and support welding tooling in described, like this when radome will deformation take place, can prevent effectively that the distortion of radome from taking place.Thereby guaranteed the shielding precision of radome itself.Support in the oblique ring of wedging cant of welding tooling in described, during installation, can be pressed in the formed deep-slotted chip breaker of sole bar reinforcement of a pair of symmetry, install easier.Sole bar reinforcement is suitable towards inclined-plane two and the described inclined-plane one of the end face of described wedging support, can guarantee the precision of positive annular.
