Description
Technical field
The utility model relates to the shielding cylinder that a kind of high-tension testing apparatus is used, and relates in particular to a kind of equipment that can guarantee shielding cylinder connection installation accuracy in being welded to connect the mouth process.
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 shielding cylinder 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 shielding cylinder, 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 shielding cylinder size when design, for shielding cylinder, his 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 shielding cylinder, but because the wall of shielding cylinder own is thin, cause the shielding cylinder distortion easily, thereby influence its circular arc degree.
The utility model content
This case technical problem to be solved: a kind of outer support welding tooling for the shielding cylinder connection is provided, can effectively prevents in being welded to connect the process of mouth owing to influenced by external force, and the deformation that produces, thereby improve welding precision.
The technical solution of the utility model is: an end of described shielding cylinder has horn mouth, and described connection is positioned at described horn mouth inboard, and the described outer welding tooling that supports comprises ring flange and folding and unfolding screw,
The periphery of described ring flange is evenly equipped with at least four tapped through holes, and described folding and unfolding screw is arranged in the described tapped through hole; The bell-mouthed maximum gauge of the internal diameter 〉=shielding cylinder of described ring flange; The height of described connection≤described shielding cylinder cylindrical shell external diameter and described ring flange internal diameter poor; Described connection is provided with for the screwed hole that connects described folding and unfolding screw.
Also comprise positioning table, the table top of described positioning table is provided with for the fixed support that supports described shielding cylinder with for the adjusting support that supports described ring flange; Described adjusting support is movably connected on the table top of described workbench by guide rail mechanism;
Described adjusting support comprises that the circular arc of level supports locating surface and the vertical orientation face vertical with the horizontal circle cambered surface, described circular arc supports the sidewall that locating surface is used for supporting described ring flange, and described vertical orientation face is used for from the side by pasting described ring flange towards described bell-mouthed end face.
The utility model because: 1) be with ring flange in the outer ring of shielding cylinder, shielding cylinder can be entangled firmly like this, can prevent from the time being subjected in welding the effect of external force like this, cause shielding cylinder to deform; In addition, in when welding because the existence of welding stress, can cause the shielding cylinder local deformation, and the outer support welding tooling of employing shielding cylinder connection, described connection is close to shielding cylinder, described welding stress is evenly distributed, thereby plays the existence of the problem that effectively prevents local deformation, effectively prevents the deformation of shielding cylinder.Thereby guaranteed the shielding precision of shielding cylinder itself.In addition, because the existence of ring flange is arranged, can guarantee the frock precision of connection, thereby guarantee the frock precision of shielding cylinder itself.2) owing to adopt positioning table, shielding cylinder and ring flange can accurately be located, thereby guarantee the frock precision of connection.
