Abstract
The utility model provides a novel structure apparatus for overlapping horizontal buses and branch buses in a low pressure cabinet, comprising horizontal conflux buses and branch buses and characterized by comprising a pair of up and down arranged connectors; the bottom surface of an upper connector is provided with a plurality of upper bus grooves and the top surface of a lower connector is provided with lower bus grooves corresponding with the upper bus grooves; the upper portions of the horizontal conflux buses are embed in the upper bus grooves and the lower portions are embed in the lower bus grooves; the branch buses are in fixed connection with the upper connector or the lower connector through connection bolts. The advantages of the utility model lie in that the apparatus has a simple structure and is convenient to maintain; when a low pressure cabinet works, the temperature rise of the horizontal conflux buses is guaranteed to be in a normal section, which substantially raises a current carrying capability of the horizontal conflux buses in real use, thereby raising operation stability and reliability of electrical equipment.
Description
Technical field
The utility model relates to low tension gas holder main split bus bridging arrangement, the new structure device of horizontal bus rod and branch bar overlap joint in particularly a kind of low-tension switch cabinet.
Background technology
At present, master, branch bar in the low tension gas holder adopt traditional overlapping mode, like Fig. 1,2, shown in 3, are directly at horizontal bus rod and branch bar perforate overlap joint between the two.When the switch cubicle rated load, horizontal bus rod carries very big rated current, because perforate is too much on the horizontal bus rod; It is overheated that horizontal bus rod current is produced in lap-joint; Also, be easy to cause horizontal bus rod temperature rise too high, reduce its current capacity with certain eddy current harm; Thereby cause system normally not move, even the whole paralysis of electrical system.In view of the foregoing, demand a kind of novel horizontal bus and branch bar connected mode urgently.
The utility model content
The utility model purpose is to overcome to exist the bus temperature rise too high in the prior art, reduces the problem of its current capacity, has proposed the new structure device of interior horizontal bus of a kind of low-tension switch cabinet and branch bar overlap joint.
To achieve these goals; The technical scheme of the utility model is achieved in that the new structure device of interior horizontal bus of a kind of low-tension switch cabinet and branch bar overlap joint; Comprise: horizontal bus rod, branch bar; It is characterized in that: also comprise a pair of connector that is provided with up and down, bottom surface of connector is provided with a plurality of Up Highway UHW grooves on this, and the end face of this time connector is provided with and the corresponding Down Highway groove of said Up Highway UHW groove; Said horizontal bus rod top is embedded in the Up Highway UHW groove, and its underpart is embedded in the Down Highway groove; Be fixedly connected with last connector or following connector through connecting bolt on the said branch bar.
Preferably, said Up Highway UHW groove has 2,3,4 or 5.
Preferably, said branch bar is provided with the bus fixing hole that is connected usefulness with last connector or following connector, on upper and lower connector, is provided with the connector fixing hole corresponding with the bus fixing hole.
By means of said structure; The utlity model has following advantage: apparatus structure is simple; Easy to maintenance, during low-voltage cabinet work, horizontal bus rod temperature rise guarantees in normal interval; Current capacity during actual use of having improved horizontal bus rod greatly, thus stability, the reliability of electric equipment operation improved.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Referring to Fig. 4,5 and 6; The new structure device of horizontal bus and branch bar overlap joint in shown is a kind of low-tension switch cabinet comprises: horizontal bus rod 1, branch bar 2 is characterized in that: also comprise a pair of connector 3 of setting up and down; 4; The bottom surface that should go up connector 3 is provided with a plurality of Up Highway UHW grooves 5, and the end face of this time connector 4 is provided with that (Up Highway UHW groove 5 is identical with Down Highway groove 6 quantity, correspondence about the position with said Up Highway UHW groove 5 corresponding Down Highway grooves 6; Groove width and horizontal bus rod row are thick to coincide; To guarantee that horizontal bus rod can fix in the groove securely), said horizontal bus rod 1 top is embedded in the Up Highway UHW groove 5, and its underpart is embedded in the Down Highway groove 6; Be fixedly connected with last connector 3 or following connector 4 through connecting bolt 7 on the said branch bar 2.
According to the low-voltage cabinet designing requirement, said Up Highway UHW groove can be 2, can be 3, can be 4, can be 5, also can be more.Like Fig. 4, rated current 1250A or and below, the Up Highway UHW groove only needs 2; Like Fig. 5, rated current 3150A or and below, the Up Highway UHW groove also only needs 2; Like Fig. 6, at rated current 4000A or more than reaching, 3 of Up Highway UHW groove need.
Said branch bar be provided with last connector or down connector is connected the bus fixing hole of usefulness, supply above-mentioned connecting bolt to pass, on the bottom surface of the end face of last connector or time connector, be provided with the connector fixing hole corresponding with the bus fixing hole.
During processing and manufacturing,, at first on upper and lower connector, offer the bus groove according to the said structure requirement, then, only perforate on branch bar, and horizontal bus rod need not perforate.Then, be located in bus rod between Up Highway UHW groove and the Down Highway groove, realize the fixing of bus rod.At last, pass fixing hole, above and/or under being fixed on branch bar on the connector through connecting bolt.Be not difficult to find out, use this project organization, horizontal bus rod temperature rise guarantees in normal interval, has improved the actual use current capacity of horizontal bus rod greatly, thereby has improved operation stability of equipment, reliability.
Below only expressed the execution mode of the utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection range of the utility model.Therefore, the protection range of the utility model patent should be as the criterion with accompanying claims.
