Abstract
The utility model discloses a bus mounting structure of a high voltage switch cabinet, which is characterized in that lapping surfaces of two main buses (1 and 4) are respectively arranged on two sides of branch buses (3); the lapping surface of each main bus serves as a contact surface of each branch bus (3); a gasket (7) is arranged between the two branch buses (3); and shielding cylinders (8) are arranged at the peripheries of the lapping parts. The bus mounting structure increases the lapping area of the buses, improves the through-current capability of the main buses, can efficiently reduce the temperature rise of the main buses so as to meet the requirement of heavy current, is high in mechanical strength so as to meet the requirement of dynamic and thermal stability of the switch cabinet, and has the advantages of large insulation margin, good security, simple structure and simple and convenient installation.
Description
Technical field
The utility model relates to a kind of bus mounting structure of electrical power distribution system high-tension switch cabinet.
Background technology
At present, domestic 40.5kV switch cubicle main bus bar is divided by its cross sectional shape and is mainly contained: rectangular bus bar, circular bus and D shape bus etc.Wherein, circular bus Electric Field Distribution is even, kelvin effect is little, the same cross-sectional ampacity is big, uses more extensive.Existing high-tension switch cabinet main bus bar is that some single hops connect into an integral body, and the main bus bar of adjacent two cabinets is also neat, and there is a faying surface that processes in advance the centre, and branch bar fuses two sections main bus bars by bolt.As shown in Figure 1.This bus mounting structure, electric current reaches another root main bus bar from a main bus bar by branch bar, two bolts that the connection of two main bus bars only depends on branch bar to connect.Its defective is:
1, the main bus bar faying surface is in the homonymy of branch bar, and two main bus bar faying surfaces only are the contact-making surface of a branch bar, can not satisfy the requirement of big electric current;
2, only there are two bolt in lap-joint, is difficult to satisfy moving, the heat-staple requirement of switch cubicle main bus bar;
3, there is big potential safety hazard in the Electric Field Distribution generation abrupt change of lap-joint.
The utility model content
The utility model is to provide a kind of simple in structure, mechanical strength is high, insulation is reliable, margin of safety is big high-tension switch cabinet bus mounting structure.
The utility model high-tension switch cabinet bus mounting structure comprises main bus bar, branch bar, connection spiral shell piece and bolt, it is characterized in that the faying surface of two main bus bars is in the both sides of branch bar, every main bus bar faying surface is the contact-making surface of a branch bar, be provided with pad between two branch bars, shielding cylinder is set around the lap-joint.
Shielding cylinder is made up of two semicircular cylinders, and respectively there is the shielding flange of a band O RunddichtringO at two ends, and each shielding flange is made up of two semicircular ring, will shield flange and shielding cylinder fuses by screw.Select the length of shielding cylinder according to the length of faying surface, shielding cylinder two end distance faying surfaces distance is identical.
The high-tension switch cabinet bus mounting structure that the utility model provides has increased the overlap joint area of bus, has improved the through-current capability of main bus bar, can effectively reduce the temperature rise of main bus bar, satisfies the requirement of big electric current; The mechanical strength height has satisfied moving, the heat-staple requirement of switch cubicle; Insulation margin is big, and fail safe is good.Simple in structure, simple installation is easily gone.
Description of drawings
Fig. 1 is the structural representation of existing high-tension switch cabinet bus mounting structure;
Fig. 2 is the structural representation of an embodiment of the utility model high-tension switch cabinet bus mounting structure;
Fig. 3 is the A-A cutaway view of Fig. 2.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, main bus bar A 2, spiral shell piece 3, branch bar 4, main bus bar B 5, bullet pad 6, bolt 7, pad 8, shielding cylinder 9, screw 10, shielding flange 11, O RunddichtringO
As Fig. 2, shown in Figure 3, the utility model high-tension switch cabinet bus mounting structure improves for two sections the main bus bar of original high-tension switch cabinet, main bus bar 1,4 faying surfaces are in the both sides of branch bar, every main bus bar faying surface is the contact-making surface of a branch bar, be provided with pad 7 between two branch bars 3, set bolt quantity increases, with two bolts 6, two bullet pads 5 and spiral shell piece 2 main bus bar A, main bus bar B, two branch bars 3 and pad 7 are fixed into one, shielding cylinder 8 is set around lap-joint.Select the length of shielding cylinder 8 according to the length of faying surface, 8 liang of end distance faying surfaces distances of shielding cylinder are identical.Shielding cylinder 8 is made up of two semicircular cylinders, and respectively there is the shielding flange 10 of a band O RunddichtringO 11 at two ends, and each shielding flange 10 is made up of two semicircular ring, leans on screw 9 will shield flange 10 and shielding cylinder 8 fuses.
This high-tension switch cabinet bus mounting structure has increased the overlap joint area of bus, has improved the through-current capability of main bus bar, can effectively reduce the temperature rise of main bus bar, satisfies the requirement of big electric current; The mechanical strength height has satisfied moving, the heat-staple requirement of switch cubicle; Insulation margin is big, and fail safe is good.Simple in structure, simple installation is easily gone.
