Abstract
The utility model relates to a low-voltage wire of a transformer. The low-voltage wire comprises copper bars (3) and wiring sheets (1), and is characterized by also comprising conductive bodies (2), wherein one end of each conductive body (2) is detachably connected with the corresponding copper bar (3), and the other end of each conductive body (2) is detachably connected with the corresponding wiring sheet (1). The low-voltage wire is convenient to operate, and cannot influence the transformer body and the environment.
Description
Technical field
The utility model relates to the transformer technology field, specifically is a kind of transformer low voltage lead-in wire.
Background technology
The transformer low voltage lead-in wire is connected the two ends of low pressure winding, uses copper bar as lead-in wire usually, draws the welding of back and lug plate, and this welded lead-in wire has following shortcoming:
Will use protection thing (such as the asbestos of immersion) when 1, welding and protect transformer body, because the space is little, not only operation is inconvenient, and the spark that welding produces also can be splashed to transformer and cause winding to burn out on one's body;
2, welding produces a large amount of harmful substances, and transformer body and environment are had very big influence.
Summary of the invention
The utility model technical problem to be solved is: a kind of transformer low voltage lead-in wire easy to operate, that can not impact transformer body and environment is provided.
The technical scheme that the utility model is taked is: a kind of transformer low voltage lead-in wire is provided, comprises copper bar and lug plate, it also comprises electric conductor, and an end of electric conductor is connected with copper bar is removable; The other end of electric conductor is connected with lug plate is removable.
Described electric conductor is a cable.
Described removable connection is meant that bolt connects.
Described bolt connection is meant; The end that copper bar is connected with cable is provided with the through hole that is used to wear bolt; The end that lug plate is connected with cable is provided with the through hole that is used to wear bolt, and the two ends of cable are provided with the metalwork that is electrically connected with cable, also are provided with the through hole that is used to wear bolt on the metalwork.
Described metalwork is meant copper, and a part of copper is a tubulose, a part of flat, and copper of tubular portion is socketed on the lead of cable and through punching press and is connected with lead; Through hole is located on copper of flat part.
After adopting above structure, the utility model transformer low voltage lead-in wire is compared with prior art, and following advantage is arranged: owing to be provided with the electric conductor cable; And bolted removable the connection all adopted with copper bar and lug plate in the two ends of cable, when copper bar and lug plate electrical connection, need not take welding manner; Also just avoided since the spark that welding causes to the influence of transformer body and surrounding environment; Owing to adopted the cable connection, cable takes up room less, and uses bolt to come removable the connection carried out with copper bar and lug plate in the two ends of cable; Fitting operation is very convenient, and is also comparatively quick.
Description of drawings
Accompanying drawing 1 connects sketch map for the utility model transformer low voltage lead-in wire.
Among the figure, 1, lug plate, 2, electric conductor, 2.1, metalwork, 3, copper bar, 4, coil windings.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
As shown in the figure, the utility model transformer low voltage lead-in wire comprises copper bar 3 and lug plate 1; Copper bar 3 all refers to connect the inner copper line and the outer copper line of low pressure winding two ends, and the utility model also comprises the electric conductor 2 that is electrically connected copper bar 3 and lug plate 1, and this electric conductor 2 adopts cable; And the cable cross-section area is identical; The identical electric current that can make of cable cross-section area is through out-of-date even, and the employing cable can be along with the difference of installing space, bending cable.The two ends of cable all are socketed with copper; Copper the bisector with its length is benchmark, and a part is a tubulose, a part of flat; Copper of tubular portion is socketed on the lead of cable and the lead fixed through punching press and cable is connected, and copper of the flat part is provided with through hole.
The end that copper bar 3 is connected with cable is provided with the through hole that is used to wear bolt, and the end that lug plate 1 is connected with cable also is provided with the through hole that is used to wear bolt.
During installation; Copper tubular portion is socketed in the two ends of cable; Make copper to be connected through punching press with the lead fixed of cable, with the through hole on copper of flat part respectively with copper bar 3 and lug plate 1 on through-hole alignment, bolt is passed the through hole of aligning; The nut of bolting on can be connected fastening to cable, copper bar 3 and lug plate 1.
