Description
Technical field
The utility model relates to a kind of transformer and installs additional device, especially insulating tape construction bolt.
Background technique
The places such as dry-type transformer is widely used in local lighting, tall building, airport, harbour CNC machinery, briefly dry-type transformer just refers to that iron core and winding are not immersed in the transformer in insulating oil.The type of cooling is divided into natural air cool (AN) and force Air flow (AF).During natural air cooling, transformer can run continuously for a long time under rated capacity.During forced air cooling, transformer output capacity can improve 50%.Be applicable to interrupted running overload, or emergent accident running overload; Because load loss during excess load and impedance voltage amplification are comparatively large, are in non-economy running state, therefore it should not made to be in long-time continuous running overload.Dry-type transformer is mainly divided into opening type, closed, cast-type three kinds of forms.
Dry-type transformer is in installation process, and iron core is installed fastening by angle steel as scaffold.Scaffold is in order to reach load-bearing electrical equipment mounted thereto, in order to reach insulation effect, general use insulation drawstring fixes or isolates some electrical equipments, insulation drawstring adopts U bolt to be fixed on scaffold always, owing to needing time U bolt is installed to open two corresponding mounting holes at scaffold, just can realize the object of fastening installation, so not only waste the time of fabrication and installation hole and installation, insulation drawstring also can be caused to have the phenomenon of transposition.
Model utility content
The technical problems to be solved in the utility model is: provide a kind of insulating tape construction bolt not easily causing the transposition of insulation drawstring easy for installation.
In order to solve the above problems, a kind of insulating tape construction bolt that the utility model provides, comprise insulating tape body, transverse bar and the vertical screw rod be connected in the middle of transverse bar of supports insulative band, through hole is provided with in the middle part of described transverse bar, insulating tape body residing for through hole is provided with curved mounting surface, described through hole upper end is provided with inner groovy, described vertical screw rod comprises the head that mates with inner groovy and arranges threaded bar portion, described vertical screw rod is through through hole, described transverse bar two ends are provided with radial domed nose, plush copper radius is greater than the radius of transverse bar.
Time process in, transverse bar is penetrated the end of insulating tape, makes the curved mounting surface place being in insulating tape in the middle part of transverse bar simultaneously, vertical screw rod is inserted in through-holes, the head of vertical screw rod and inner groovy coupling.Be connected with installation the electrical equipment tightened by needs by vertical screw rod to fix.
The advantage of the utility model insulating tape construction bolt is adopted to be: transverse bar and vertical screw combinations to be formed T-shaped bolt, when installing insulating mounting strap only needs to offer a mounting hole on scaffold, decreases production time and the installation time of mounting hole; Because vertical screw rod is welded on also through insulation drawstring in the middle of transverse bar, use symplex structure also passes insulating tape, makes insulating tape transposition can not occur; Described transverse bar two ends are provided with radial domed nose, the phenomenon of insulating tape scratch when preventing from operating.
Further, in order to prevent insulating tape from breakking away, the outer wall of described transverse bar is provided with grip rib, and when insulating tape is connected with transverse bar time, the adhesive ability increased between insulating tape and transverse bar by grip rib stops insulating tape to break away further.
Further, described plush copper outer wall wraps up one deck insulation plastic cement, influence electricity can be prevented to be incorporated in cross bolts and cause larger corrosive action to attachment portion.
Finally, described vertical screw rod is Stainless Steel Alloy screw rod, adopts the vertical bolt of Stainless Steel Alloy manufacture, can prevent from producing thread in cinching process damaging.
Accompanying drawing explanation
Fig. 1: the structural representation being the present embodiment insulating tape construction bolt;
Fig. 2 is transverse bar and vertical screw rod dismounting schematic diagram.
Reference character is enumerated: insulating tape body 1, transverse bar 2, vertical screw rod 3, plush copper 4, grip rib 5, through hole 6.
Embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Insulating tape construction bolt as described in Figure 1, comprise insulating tape body 1, the transverse bar 2 of supports insulative band and the vertical screw rod 3 that is connected in the middle of transverse bar 2, through hole 6 is provided with in the middle part of transverse bar 2, insulating tape body 1 residing for through hole 6 is provided with curved mounting surface, through hole 2 upper end is provided with inner groovy, vertical screw rod 3 comprises the head that mates with inner groovy and arranges threaded bar portion, vertical screw rod 3 is through through hole 6, transverse bar 2 two ends are provided with radial domed nose 4, and plush copper 4 radius is greater than the radius of transverse bar 2.Time process in, transverse bar 2 is penetrated the end of insulating tape, makes the curved mounting surface place being in insulating tape in the middle part of transverse bar 2 simultaneously, vertical screw rod 3 is inserted in through hole 6, the head of vertical screw rod 3 and inner groovy coupling.Be connected with installation the electrical equipment tightened by needs by vertical screw rod to fix.
Transverse bar and vertical screw combinations are formed T-shaped bolt, when installing insulating mounting strap only needs to offer a mounting hole on scaffold, decreases production time and the installation time of mounting hole; Because vertical screw rod is welded on also through insulation drawstring in the middle of transverse bar, use symplex structure also passes insulating tape, makes insulating tape transposition can not occur; Transverse bar two ends are provided with radial domed nose, the phenomenon of insulating tape scratch when preventing from operating.
In order to prevent insulating tape from breakking away, the outer wall of transverse bar 2 is provided with grip rib 5, when insulating tape is connected with transverse bar 2 time, stops insulating tape to break away further by grip rib 5 adhesive ability increased between insulating tape and transverse bar.Plush copper outer wall wraps up one deck insulation plastic cement, influence electricity can be prevented to be incorporated in cross bolts, cause larger corrosive action to attachment portion.Vertical screw rod is Stainless Steel Alloy screw rod, adopts the vertical bolt of Stainless Steel Alloy manufacture, can prevent from producing thread in cinching process damaging.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
