Abstract

The utility model discloses a novel alternating current bus of a rectifying unit, which comprises a hard bus (1), wherein two front flexible buses (2) which are arranged to be parallel to each other are connected at the front end of the hard bus (1), rectifier cabinet end connecting plates (4) with bolt holes are respectively connected on the front flexible buses (2), the rear end of the hard bus (1) is connected with a rear flexible bus (3), and a transformer end connecting plate (5) with the bolt hole is connected on the rear flexible bus (3). The flexible buses which are in the structure of flexible copper strips are connected at the front end and the rear end of the existing hard bus, and the connecting plates are further connected on the flexible buses, thereby greatly facilitating the field installation; furthermore, the novel alternating current bus can conveniently increase the outlet interval between the buses during the installation, effectively avoid the short circuit and the heating between the buses due to the connection problem and ensure the normal work of a rectifier transformer device. The novel alternating current bus has the advantages of simple structure, easy manufacture, convenient installation, safe and reliable use and the like.

Description

The novel ac bus of Rectification Power Factor

Technical field

The utility model relates to the novel ac bus of Rectification Power Factor of the usefulness of transmitting electricity between a kind of rectifier transformer and the rectifier cabinet, belongs to transmission of electricity bus technical field.

Background technology

Need the factory of direct current supply at electrolysis plant or other, usually adopt copper busbar to connect between from the rectifier transformer to the rectifier cabinet.When the transformer adopting cophase counter parallel connection, it goes out distance between centers of tracks and is generally 150～200mm, but because general ac bus is that the hard bus of multistage connects by bolt, this installs very inconvenient at the scene, but also be easy to cause point discharge owing to the reason of bolt, thereby make the phenomenon that is short-circuited between bus, influence the normal operation of equipment, even cause accidents such as device damage.Therefore, the structure of existing Rectification Power Factor ac bus still is not ideal enough.

The utility model content

The purpose of this utility model is: provide a kind of simple in structure, easy for installation, safe and reliable Rectification Power Factor novel ac bus, to overcome the deficiencies in the prior art.

The utility model is to constitute like this: the novel ac bus of a kind of Rectification Power Factor of the present utility model, be on existing hard bus basis, to improve to form, front end at hard bus is connected with two preceding soft buses that are arranged parallel to each other, before every, be connected with the rectifier cabinet end connecting plate that has bolt hole on the soft bus respectively, be connected with the soft bus in back in the rear end of hard bus, on the soft bus in back, be connected with the transformer terminal connecting plate that has bolt hole.

All be provided with between the rectifier cabinet end connecting plate between two preceding soft buses that are arranged parallel to each other and before being connected on the soft bus at interval.

On the transformer terminal connecting plate, be provided with the opening groove.

Above-mentioned hard bus, rectifier cabinet end connecting plate and transformer terminal connecting plate all are the hard copper plate structure; The soft bus of soft bus and back is the soft copper band structure before above-mentioned.

Be connected by the fusion casting type joint between above-mentioned preceding soft bus and hard bus and the rectifier cabinet end connecting plate; The soft bus in back with firmly also be connected between bus and the transformer terminal connecting plate by the fusion casting type joint.

Owing to adopted technique scheme, the utility model has all connected the soft bus of soft copper band structure in the front-end and back-end of existing hard bus, and on soft bus, reconnect connecting plate, so just be convenient to on-the-spot the installation greatly, and can increase the distance between centers of tracks that goes out between bus and the bus when mounted easily, can avoid the short circuit and the heating that cause because of connectivity problem between the bus effectively, and guarantee the operate as normal of rectifier transformer equipment.Therefore, the utility model compared with prior art the utlity model has advantages such as simple in structure, that making is easy, easy for installation, safe and reliable.

Embodiment

Embodiment of the present utility model: structure of the present utility model as depicted in figs. 1 and 2, during making, hard bus 1, rectifier cabinet end connecting plate 4 and transformer terminal connecting plate 5 all adopt the hard copper plate that uses as bus in the prior art, and the soft bus 3 in preceding soft bus 2 and back adopts existing soft copper band structure; During making, connect two preceding soft buses 2 that are arranged parallel to each other at the front end of hard bus 1, and have the rectifier cabinet end connecting plate 4 of bolt hole on before every, connecting respectively on the soft bus 2, between two preceding soft buses 2 that are arranged parallel to each other and before being connected, between the rectifier cabinet end connecting plate 4 on the soft bus 2 certain interval 6 is set all, the distance at interval 6 is controlled at 5～25 millimeters scope; Connect the soft bus 3 in back in the rear end of hard bus 1 then, on the soft bus 3 in back, connect the transformer terminal connecting plate 5 that has bolt hole, and on transformer terminal connecting plate 5, produce 2～4 opening grooves 7; When being connected with rectifier cabinet end connecting plate 4 with hard bus 1, preceding soft bus 2 preferably adopt fusion casting type joint of the prior art to connect; Equally, when will the soft bus 3 in back being connected with transformer terminal connecting plate 5, also adopt fusion casting type joint connection of the prior art with hard bus 1.
