Abstract
The utility model discloses a fixing device for a connecting component between a transformer and a power distribution line. the fixing device comprises a steel plate, wherein the steel plate is provided with through-wall bushing holes, installation holes used for fixing the steel plate are arranged around each through-wall bushing hole, the steel plate is provided with vertical gaps, each of the gaps is communicated to the corresponding through-wall bushing hole from the bottom edge of the steel plate, and the gaps are welded by brazing. According to the fixing device for a connecting component between a transformer and a power distribution line, as the gaps are opened in the vertical direction, the integrity of the steel plate can be guaranteed, the installation is made convenient, the steel plate can be directly fixed on a wall, the phenomenon of eddy-current loss and heat emission can be avoided, the mechanical strength of the device can be guaranteed, the complicated construction procedure is greatly simplified, and through-wall bushings can be installed more stably and more reliably.
Description
Technical field
The utility model relates to the fixture between a kind of transformer and distribution line, is specifically related to the fixture of link between a kind of transformer and distribution line.
Background technology
Wall bushing is the important link between transformer and distribution line, connects main transformer low-pressure side lead-out wire and 35kV, 10kV switch gear room.When electric current is flowed through main busbar, can excite a magnetic field on the wall bushing plate that wall bushing is fixed on body of wall, due to the electric current change at random, this magnetic field is the variation magnetic field.When conductor was in time dependent magnetic field, the energy loss that the electric current of inducting in conductor causes was called eddy current loss.Eddy current loss can increase and sharply increase along with the bus operating current, this problem more so during meeting the kurtosis summer, the ampacity of bus and the electric component particularly normal operation of wall bushing body and safety in operation and the power supply reliability of whole piece circuit have been had a strong impact on, even jeopardize personal safety, produce huge economic loss and negative effect.
Wall bushing plate fever phenomenon usually occurs in annual meeting period in kurtosis summer, and two salient features are arranged this period: the one, and ambient air temperature is high, and the 2nd, in the switch gear room, main busbar load is large, very easily causes the heating of wall bushing plate.In order to improve the loss of eddy current loss heating, can adopt an effective measure on original structure and disconnect the closed-loop path, then use plugging material (brass weld seam) that otch is sealed, to avoid near the steel member heavy current busbar to form the closed-loop path that surrounds, usually the method for taking is as shown in Figure 1: the wall bushing plate is spliced by upper and lower two block plates, middle reserving gaps 4 ' adopts brazing to weld, thereby improves the phenomenon of eddy current loss heating.But this mode has not only been destroyed the globality of wall bushing plate, makes its mechanical strength not to be guaranteed, and, can increase difficulty of construction during installation, extend construction period.In addition, this mode can not be guaranteed the relatively accurate position of wall bushing installing hole, and must reserve the joint-cutting of wall bushing installation perforate and brazing before steel plate is fixing, again makes otherwise can do over again.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides the fixture of link between a kind of transformer and distribution line, by vertical direction is adjusted in the gap, make the steel plate globality remain intact, improved the mechanical performance of steel plate.
Technical scheme: for achieving the above object, the fixture of link between a kind of transformer of the present utility model and distribution line, comprise steel plate, described steel plate is provided with the wall bushing hole, wall bushing hole periphery is provided with the installing hole for fixation steel plate, steel plate is provided with the gap from the connection wall bushing hole, bottom of steel plate, and described gap adopts brazing to weld.
The width in described gap is 3 ~ 5mm, for example can be 3mm, 4mm 5mm equidimension.
Described wall bushing hole has three, and the number that each wall bushing hole periphery is provided with installing hole is four, and each wall bushing hole has the gap to be communicated to the wall bushing hole from the steel plate bottom, and the gap connects with brazing.
Beneficial effect: the fixture of link between a kind of transformer of the present utility model and distribution line, by in the vertical direction is opened in the gap, can guarantee the integrality of steel plate, make easy for installation, steel plate directly is fixed on body of wall, can solves the phenomenon of eddy current loss heating, and its mechanical strength is guaranteed, also can greatly simplify numerous and diverse program of construction, make the installation of wall bushing more firm and firm.
Description of drawings
Fig. 1 is the structural representation figure of existing apparatus;
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the fixture of link between a kind of transformer of the present utility model and distribution line, comprise steel plate 1, steel plate 1 is provided with wall bushing hole 2, wall bushing hole 2 peripheries are provided with the installing hole 3 for fixation steel plate 1, steel plate 1 is provided with gap 4, and gap 4 is connected to wall bushing hole 2 from the bottom of steel plate 1, and gap 4 adopts brazings to weld.
In the utility model, the width in gap 4 is 3 ~ 5mm, for example can be 3mm, 4mm 5mm equidimension, when gap width is 5mm, the brazing welding of 5mm is adopted in gap 4, and wall bushing hole 2 has three, and the number that each wall bushing hole 2 peripheries are provided with installing hole 3 is four, each wall bushing hole 2 is provided with gap 4, and gap 4 all just connects with brazing.
In the utility model, directly by installing hole 3, steel plate 1 is fixed on body of wall, owing to being provided with installing hole 3 around each wall bushing hole 2, make steel plate 1 install firmly, because gap 4 arranges in the vertical direction, make steel plate 1 as a whole, the globality that can keep steel plate 1, mechanical strength increases greatly, and can avoid the phenomenon of eddy current loss heating, simplifies working procedure.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
