Description
Technical field
The utility model belongs to field of electricity construction, particularly relates to distribution transformer structure for installing lightning arrester.
Background technology
In distribution transforming lightning arrester installation and operation management, Problems existing is more, burns transformer, bursts the accidents such as lightning arrester and happen occasionally.Traditional structure for installing lightning arrester, by copper core and copper crimp head connected mode between three-phase lightning protector, needs two copper cores and 4 copper crimp head, complex structure, installs inconvenience, and not easily installs owing to damaging, puncturing, under the environment such as corrosion.
Therefore, need to change mounting structure and method, make the mounting means of lightning arrester more simple and easy to do.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of distribution transformer structure for installing lightning arrester, and convenient installation, reliability is higher.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of distribution transformer structure for installing lightning arrester, comprise the mounting bracket of a L-type, described mounting bracket is made up of the level board of a rectangle and the vertical plate of the rectangle vertical with this level board, bottom described level board, the left and right sides is provided with the fixed head of the strip structure extended to distribution transformer, described fixed head one end is fixed by bolt and level board, the described fixed head other end is fixed by bolt and distribution transformer top, the stacked grounding copper bar being fixed with rectangle in plane on described level board, the level board of described grounding copper bar and mounting bracket, fixed head is fixing by bolt one, described level board is provided with lightning arrester along its length, the grounding leg of described lightning arrester is arranged in grounding copper bar formed with grounding copper bar and is electrically connected, described grounding copper bar one end is vertically provided with a grounding head, described grounding head is connected with earth connection.
Preferably, institute described level board and grounding copper bar on diagonal angle correspondence be provided with location hole, be plugged with alignment pin in location hole.
Preferably, described distribution transformer adjoins grounding head and is provided with an insulating clamp given prominence to laterally, and described earth connection passes insulating clamp after grounding head is drawn.
Preferably, described grounding head is earth stud.
Preferably, described lightning arrester is column support type zinc oxide arrester.
The utility model improves structure for installing lightning arrester, copper core between original three-phase lightning protector and copper crimp head syndeton is replaced by grounding copper bar, the grounding leg of three-phase lightning protector is arranged in grounding copper bar formed with grounding copper bar and is electrically connected, grounding copper bar one end is vertically provided with a grounding head, grounding head connects earth connection again, simple and reasonable, only need a grounding copper bar, just can replace original two copper cores and 4 copper crimp head, field fabrication and set-up time are greatly saved, particularly during power failure repairing, race against time, use grounding copper bar to install and significantly can reduce interruption duration, Be very effective, and owing to eliminating copper crimp head, the combination of lightning arrester and grounding copper bar is tightr, contact resistance is less, reliability is higher.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is Facad structure schematic diagram of the present utility model;
Fig. 2 is side structure schematic diagram of the present utility model.
Embodiment
A kind of distribution transformer structure for installing lightning arrester of the utility model is illustrated below in conjunction with Fig. 1 and Fig. 2, it comprises the mounting bracket 1 of a L-type, described mounting bracket 1 is made up of the level board of a rectangle and the vertical plate of the rectangle vertical with this level board, bottom described level board, the left and right sides is provided with the fixed head 11 of the strip structure extended to distribution transformer, described fixed head 11 one end is fixed by bolt and level board, described fixed head 11 other end is fixed by bolt and distribution transformer top, the stacked grounding copper bar 2 being fixed with rectangle in plane on described level board, the level board of described grounding copper bar 2 and mounting bracket, fixed head 11 is fixing by bolt one, described level board is provided with lightning arrester 3 along its length, the grounding leg of described lightning arrester 3 is arranged in grounding copper bar 2 formed with grounding copper bar 2 and is electrically connected, described grounding copper bar 2 one end is vertically provided with a grounding head 21, described grounding head 21 is connected with earth connection.
Owing to being replaced copper core between original three-phase lightning protector and copper crimp head syndeton by copper bar, the grounding leg of three-phase lightning protector is arranged in grounding copper bar formed with grounding copper bar and is electrically connected, grounding copper bar one end is vertically provided with a grounding head, grounding head connects earth connection again, simple and reasonable, only need a grounding copper bar, just can replace original two copper cores and 4 copper crimp head, field fabrication and set-up time are greatly saved, particularly during power failure repairing, race against time, use grounding copper bar to install and significantly can reduce interruption duration, Be very effective, and owing to eliminating copper crimp head, the combination of lightning arrester and grounding copper bar is tightr, contact resistance is less, reliability is higher.
On described level board and grounding copper bar, on diagonal angle, correspondence is provided with location hole, is plugged with alignment pin in location hole.Fix again after first grounding copper bar being located, improve installation effectiveness, also facilitate the installation of lightning arrester.Described distribution transformer adjoins grounding head and is provided with an insulating clamp given prominence to laterally, and described earth connection passes insulating clamp after grounding head is drawn, and can locate dead earth line.Described grounding head is earth stud, conveniently installs earth connection.Described lightning arrester is column support type zinc oxide arrester.
