During the use, the link of copper bar and drawer are qualified for the next round of competitions a terminal and are connected, and big cable effort can be born enough to the stiff end fixed stay on the cabinet body structure, the cable of being qualified for the next round of competitions passes through overlap joint hole overlap joint on the copper bar, prevents that the drawer is qualified for the next round of competitions a terminal and receives cable tensile force and the easy impaired circumstances, has protected the drawer terminal of being qualified for the next round of competitions a time.
Description
Technical field
The utility model relates to a kind of structure of copper bar and use the low-tension switch cabinet of this structure of transferring.
Background technology
Copper bar, also known as copper bus-bar or copper bus-bar, is made by copper product, and cross section is the long conductor of rectangle or chamfering rectangle, plays conveying electric current in circuit and is connected electric equipment.Copper bar, at electric equipment, is particularly widely used in complete set of equipments.At present, the drawer outlet cable of low-tension switch cabinet is directly overlapped on drawer outlet terminal mostly.Because be subject to the active force of cable, drawer outlet terminal is easily damaged.In addition, when cable is too much, when especially using nonstandard cable, cable will overlap.
Utility model content
The purpose of this utility model is that providing a kind of can protect the switching structure of copper bar of a drawer outlet terminal and use the low-tension switch cabinet of this structure.
For achieving the above object, the technical scheme of the utility model switching structure of copper bar is: switching structure of copper bar comprises copper bar, copper bar has link for being connected with drawer outlet terminal and for the stiff end of insulating supporting on cabinet, copper bar is provided with the overlap joint hole for overlapping outlet cable.
Described copper bar is " L " type structure, and comprise crosspiece and perpendicular section, described stiff end is positioned at the one end away from perpendicular section on crosspiece, and described link is positioned at the one end away from crosspiece in perpendicular section, and described overlap joint hole is located on crosspiece.
Described overlap joint hole has several, and is arranged at intervals on copper bar.
Described structure of copper bar comprises A, B, C, N tetra-copper bar described in phase, four phase copper bars with interval, form arrangement successively, the link of four phase copper bars is mutually concordant.
Overlap joint hole on adjacent two-phase copper bar is in staggered distribution mutually.
The technical scheme of the utility model low-tension switch cabinet is: low-tension switch cabinet comprises cabinet, cabinet is provided with switching structure of copper bar, switching structure of copper bar comprises copper bar, copper bar has link for being connected with drawer outlet terminal and for the stiff end of insulating supporting on described cabinet, copper bar is provided with the overlap joint hole for overlapping outlet cable.
Described copper bar is " L " type structure, and comprise crosspiece and perpendicular section, described stiff end is positioned at the one end away from perpendicular section on crosspiece, and described link is positioned at the one end away from crosspiece in perpendicular section, and described overlap joint hole is located on crosspiece.
Described overlap joint hole has several, and is arranged at intervals on copper bar.
Switching structure of copper bar comprises A, B, C, N tetra-copper bar described in phase, four phase copper bars with interval, form arrangement successively, the link of four phase copper bars is mutually concordant.
Overlap joint hole on adjacent two-phase copper bar is in staggered distribution mutually.
The beneficial effects of the utility model are: during use, and link and drawer outlet terminal of copper bar is connected, and stiff end is fixedly supported on cabinet body structure, can bear enough large cable active force; Outlet cable is overlapped on copper bar by overlap joint hole, prevents drawer outlet terminal to be subject to cable tension effect and easy impaired situation, protects drawer outlet terminal.
Further, overlap joint hole has several, and is arranged at intervals on copper bar.Make copper bar effectively expand the faying surface of an outlet terminal, be applicable to the situation of multiple outlet cable, go for the cable bond of various special circumstances, the connectivity problem of nonstandard cable can be solved, highly versatile.
Accompanying drawing explanation
Fig. 1 is the structural representation of the switching structure of copper bar of the embodiment 1 of the utility model low-tension switch cabinet;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of the switching structure of copper bar of the embodiment 2 of the utility model low-tension switch cabinet.
Embodiment
Below in conjunction with accompanying drawing, execution mode of the present utility model is described further.
The embodiment 1 of low-tension switch cabinet of the present utility model, as shown in Figure 1 to Figure 2, low-tension switch cabinet comprises cabinet, cabinet is provided with switching structure of copper bar, switching structure of copper bar comprises A phase copper bar 11, B phase copper bar 12, C phase copper bar 13 and N phase copper bar 14, A, B, C, N tetra-phase copper bar be " L " type structure comprising crosspiece and perpendicular section, A, B, C, N tetra-phase copper bar with interval, the arrangement of form successively, with anti-interference.Copper bar has link and stiff end, stiff end is positioned at the one end away from perpendicular section on crosspiece, link is positioned at the one end away from crosspiece in perpendicular section, the link of copper bar is connected by bolt 4 and drawer outlet terminal 3, the stiff end of copper bar is fixed on cabinet by insulated support 2, the link of four phase copper bars is mutually concordant, on the crosspiece of copper bar, interval is provided with several overlap joint holes 10, overlap joint hole 10 is the gauge orifice for overlapping outlet cable, overlap joint hole 10 on adjacent two-phase copper bar is in staggered distribution mutually, is convenient to overlap joint.
During use, the link of copper bar is arranged on drawer outlet terminal, and stiff end is supported on cabinet body structure, can bear enough large cable active force.During outlet cable overlap joint, be directly overlapped on copper bar, thus protect drawer outlet terminal, prevent drawer outlet terminal to be subject to cable tension effect and easy impaired situation.Copper bar effectively expands outlet terminal faying surface, go for the cable bond of various special circumstances, the connectivity problem of nonstandard cable can be solved, switching structure of copper bar highly versatile, easy for installation, can use on the low pressure drawer-type switch cabinets such as MNS, GCS, GCK.
