Abstract
The utility model relates to a board -like magnetic screen ground structure, including fastening in together magnetic screen board and folder extension board and cardboard between the two, magnetic screen board one side be connected with the earth lug, the earth lug head end connect to the magnetic screen board, the through -hole has been seted up to the end and the earth lug end connects to the folder extension board. The utility model discloses a reliable contact of magnetic screen board and folder extension board is realized to the earth lug, avoids the transformer when vibration in service is great, and the not hard up suspension that causes the magnetic screen board of insulating fastener produces the suspension and discharges, influences the operation of transformer.
Description
Technical field
This utility model is related to transformator shielding techniques field, and in particular to a kind of board-like magnetic shield ground structure.
Background technology
Board-like magnetic shield is a kind of conventional shielding mode in transformator magnetic shield.High-power transformer inside device body end
Portion's leakage field is very big, is impact of the effective control brow leakage to folder and neighbouring hardware, frequently with board-like magnetic shield.
Board-like magnetic shield have simple structure, it is easy to process, be easy to assembling, the features such as leakage field control effect is obvious.Board-like magnetic in operation
Shielding should will suspend with folder reliable contacts, otherwise magnetic shield panel, and generation office puts, and affects the normal operation of transformator.
In the past the earthing mode of magnetic shield panel was not painted using folder with magnetic shield contact site, will by insulated fasteners
Magnetic shield panel is fixed on folder, and using contact of the magnetic shield panel with folder the ground connection of magnetic shield panel is realized.Because transformator exists
Vibrate larger in operation, insulated fasteners easily loosen, cause the suspension of magnetic shield panel, produce suspended discharge, affect transformator
Operation.
The content of the invention
For the problems referred to above, this utility model provides one kind in Transformer, it is ensured that board-like magnetic shield reliable ground,
Avoid the board-like magnetic shield ground structure of suspended discharge.
To solve the above problems, the technical scheme that the present invention takes is：A kind of board-like magnetic shield ground structure, including fastening
Cardboard in magnetic shield panel together and folder support plate and between the two, described magnetic shield panel side is connected with ground strip；
Described ground strip head end is connected to magnetic shield panel, and end offers through hole and ground strip end is connected to folder support plate.
Described ground strip is formed using the thick tin plating copper belts of 0.3mm are two-fold.
Described folder support plate is provided with a hole near the end of ground strip, and through hole and the silk hole of ground strip end are inserted into tightly
Ground strip is fixed on folder support plate by firmware.
Described ground strip head end is sandwiched between the first stalloy of magnetic shield panel bottom and the second stalloy, ground strip with
The first stalloy lap of splice is that 50mm ensures reliable conducting, and both weld together.Magnetic shield panel is compressed after welding.
Preferably, magnetic shield panel and folder support plate are fastened by insulation blanket stud.
Preferably, the calliper is 0.5mm.
This utility model realizes the reliable contacts of magnetic shield panel and folder support plate by ground strip, it is to avoid transformator is in operation
When middle vibration is larger, insulated fasteners loosen and cause the suspension of magnetic shield panel, produce suspended discharge, affect the operation of transformator.

Specific embodiment
A kind of board-like magnetic shield ground structure, including by insulation blanket stud 1 magnetic shield panel 2 together and folder are anchored on
Plate 3 and the cardboard 4 that thickness between the two is 0.5mm, the described side of magnetic shield panel 2 is connected with tin plating using 0.3mm thickness
The two-fold ground strip 5 of copper belt；The described head end of ground strip 5 is sandwiched in the first stalloy 6 and second of the bottom of magnetic shield panel 2
Between stalloy 7, the lap of splice of 5 and first stalloy of ground strip 6 is 50mm, and both weld together；End offers logical
Hole 8, described folder support plate 3 is provided with a hole near the end of ground strip, and through hole 8 and the silk hole of the end of ground strip 5 are inserted into tightly
Ground strip 5 is fixed on folder support plate 3 by firmware 9.
