The shield cover is for having the not closed annular structure of hoop open -ended, the shield cover includes the bottom ring board and locates the flank bent plate of the outside extension of bottom ring board both sides immediately that both sides wing bent plate is buckled in opposite directions, forms the circumference groove that is used for supplying the strap to pass through between both sides wing bent plate and the bottom ring board. The utility model discloses shield cover structure after the improvement only needs spinning technology adding man -hour, and simple process has reduced the degree of difficulty of shield cover processing.
Description
Technical field
The utility model relates to High-Voltage Electrical Appliances field, is specifically related to a kind of radome and uses the voltage transformer of this radome.
Background technology
In gas-insulated voltage transformer, usually outside a winding, be provided with radome, the overall Electric Field Distribution of device body can be made even, protective winding when industrial frequency withstand voltage and lightning impulse time be not damaged.
Notification number is CN201601013U, the day for announcing is that the Chinese patent document on October 6th, 2010 discloses a kind of voltage transformer, the radome that this voltage transformer comprises a winding and is set on the outer circumference surface of a winding, this radome is the hollow tubular body structure of annular, radome is made up of two circular arc assemblies, upper at two circular arc assemblies, bottom is welded with plug respectively, wherein be positioned on the plug below a winding and offer through hole, insulation board is equipped with between two through hole, be positioned on the plug above a winding and be welded with connecting plate, two connecting plates are connected by bolt.One end of two circular arc assemblies is connected by insulation board, and by be convexly equipped in respectively, connecting plate on the outer circumference surface of end is removable to be connected the other end, thus radome is held tightly be fixed on the outer peripheral face of a winding.Plug, connecting plate are weldingly fixed on circular arc assembly end adding man-hour requirement by the radome of this structure, need welding, the process such as level and smooth of polishing, complex process, and radome amount of parts used is many, waste raw material.
Utility model content
The purpose of this utility model is to provide a kind of processing technology simple radome, and uses the voltage transformer of this radome.
For achieving the above object, the technical scheme of the utility model radome is: radome is the not closed circulus with hoop opening, described radome comprises bottom circumferential lamella and is erected on the outward extending flank bent plate of bottom circumferential lamella both sides, two flank bent plates bend in opposite directions, form the circumferential slot being used for passing through for band between two flank bent plates and bottom circumferential lamella.
Described radome is structure as a whole.
Described flank bent plate is connected with bottom circumferential lamella rounding off.
Described band is shrink belt.
The technical scheme of the voltage transformer of the utility model use radome is: the radome that voltage transformer comprises a winding and is set on the outer circumference surface of a winding, described radome is the not closed circulus with hoop opening, described radome comprises bottom circumferential lamella and is erected on the outward extending flank bent plate of bottom circumferential lamella both sides, two flank bent plates bend in opposite directions, circumferential slot is formed between two flank bent plates and bottom circumferential lamella, described voltage transformer comprises shrink belt, and shrink belt is wrapped on bottom circumferential lamella by described circumferential slot.
Described radome is structure as a whole.
Described flank bent plate is connected with bottom circumferential lamella rounding off.

The beneficial effects of the utility model are: the shielding case structure after the utility model improves only needs spinning process adding man-hour, and technique is simple, reduces the difficulty of radome processing.
Further, radome is structure as a whole, and flank bent plate is connected with bottom circumferential lamella rounding off, and electric field can be avoided to concentrate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of voltage transformer of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the sectional view of radome in Fig. 1;
Fig. 4 is the A-A cutaway view in Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, execution mode of the present utility model is described further.
The specific embodiment of voltage transformer of the present utility model, as shown in Figures 1 to 4, voltage transformer comprises the winding 2, radome 1 and the shrink belt 3 that arrange from inside to outside, and radome 1 is set in the outside of a winding 2.The not closed circulus that radome 1 is integrated, the not closed part of this circulus is hoop opening 13, radome 1 comprises bottom circumferential lamella 12 and is erected on the outward extending flank bent plate 11 of bottom circumferential lamella 12 both sides, two flank bent plates 11 bend in opposite directions, all be connected with bottom circumferential lamella 12 rounding off, radome 1 also comprises the circumferential slot 14 formed between the bending part of two flank bent plates 11 and bottom circumferential lamella 12.During use, by the circumferential slot 14 of shrink belt 3 by outer portion, be wrapped on bottom circumferential lamella 12.By tightening up shrink belt 3, bottom circumferential lamella 12 is pressed on the outer peripheral face of a winding 2.When processing radome 1, only needing rotary pressing processing technique, reducing the difficulty of processing of radome, connect parts without the need to other simultaneously, save raw material, reduce cost.
In other embodiments, in order to easy for installation, radome can also be set to the segmental structure be connected by connector.
In other embodiments, shrink belt can also replace with the band that other can play banding effect.
The structure of radome of the present utility model is identical with the structure of the radome in above-described embodiment, repeats no more.
