Abstract
The invention provides an 'H'-shaped section bus of a switchgear set. The 'H'-shaped section bus is characterized in that the section of the bus is 'H'-shaped, two U-shaped grooves are respectively arranged on two narrow faces of the bus, and a contact plane is a smooth broad face. The invention further provides a lapping device of the 'H'-shaped section bus of the switchgear set, and the lapping device is characterized in that the contact plane of the two 'H'-shaped section buses is appressed through fastening bolts. Compared with conventional rectangular section buses, the 'H'-shaped section bus of the switchgear set is higher in rigidity, larger in surface area, high in resistance to sudden accidents and good in radiating effect, the lapping device is large in effective contact area and small in contact resistance and heat productivity, and the overall technological performance of the switchgear set is improved.
Description
Technical field
The present invention relates to a kind of switchgear assembly " H " type cross section bus and lap device thereof; Be used for switchgear assembly production, manufacture process; Improve the rigidity of the bus in the primary circuit in the switchgear, reduce the caloric value at busbar joint place, belong to power transmission and distribution industry technology field.
Background technology
In power transmission and transformation system, switchgear assembly is extremely important part, is realizing the conveying and the distribution of electric energy.In the production of switchgear assembly, manufacture process, bus is the conductive carrier of primary circuit, is connected on request, assembles with other major component (like circuit breaker etc.), forms the primary circuit of switchgear.The effect of bus is to compile, distribute and transmit electric energy, generally selects for use by the temperature rise principle, and when in the bus during through rated current, its temperature rise should not be elevated to allowable value.Comparatively speaking, the temperature of its joint than the temperature of other part on the bus rise sooner, caloric value is bigger, the temperature rise that solves its joint is that the primary circuit median generatrix is normal, the key of safe operation.
The most frequently used bus is that the cross section is the rectangular bus bar of rectangle in the switchgear assembly at present, and overlapping mode commonly used is to open installing hole, its assembling is firm with securing member at joint area between the rectangular bus bar, and electric current passes through in the assurance primary circuit.There are following shortcoming in rectangular bus bar and lap device commonly used thereof:
1, rectangular bus bar is the section bar that forms through drawing, considers technical matters and processing cost, and its surface roughness, flatness generally are not very high, and the contact effect of contact-making surface is not very desirable during assembling;
2, the material of rectangular bus bar is generally copper or aluminium, and Material Strength is softer relatively, is receiving under the external force effect, is easy to generate bigger distortion, has influence on the overlap joint effect of contact-making surface;
3, when assembling with securing member, owing to receive bigger active force, its contact situation is better near the securing member place, because the distortion of bus, its effective contact area is not very big away from the contact-making surface at securing member place, and contact resistance is higher, is easy to heating;
4, the simple shape of rectangular bus bar, the external force resistance effect is little, bus under fault state owing to receive very big electrodynamic action, more yielding, the hidden danger that has the fault of making further to enlarge.
Summary of the invention
The technical problem that the present invention will solve is to the rectangular bus bar in the existing switchgear assembly and the deficiency of building device thereof, through changing the shape of busbar cross-section, a kind of " H " type cross section bus and lap device thereof that increases rigidity and radiating effect is provided.
In order to solve above-mentioned first technical problem; Technical scheme of the present invention provides a kind of switchgear assembly " H " type cross section bus; It is characterized in that: busbar cross-section is " H " type, and two U-lags are located at respectively on two leptoprosopy of bus, and contact plane is smooth wide.
In order to solve above-mentioned second technical problem, technical scheme of the present invention provides a kind of switchgear assembly " H " type cross section bus lap device, it is characterized in that: the contact plane of two " H " type cross section buses is close to through fastening bolt.
Preferably, said fastening bolt is 4.
A kind of switchgear assembly provided by the invention " H " font cross section bus is compared with traditional rectangular cross section bus, and under the constant situation of busbar cross-section area and bus thickness, " H " font cross section bus rigidity is higher, surface area is bigger.Rigidity increases, and can increase bus to the resistance of external force greatly that burst accident produces, and makes it not yielding, has improved fail safe, the reliability of system's operation; Surface area increases, and radiating effect is better, and the heat that the joint produces when two bus overlap joints also can be very soon to outdiffusion.When length, material, area of section and thickness homogeneous phase while, " H " font cross section bus is compared traditional rectangular cross section bus under same temperature rise situation, can allow the bigger electric current that passes through of bus.
A kind of switchgear assembly provided by the invention " H " font cross section bus lap device makes that the contact plane of two " H " type cross section buses is close to, U-lag is outside; Its contact-making surface is an even curface; Fastening bolt is positioned on the contact plane, makes the stressed more even of contact-making surface place, and effectively contact area is bigger; Contact resistance is reduced greatly, also reduced caloric value simultaneously.
A kind of switchgear assembly provided by the invention " H " type cross section bus compares that traditional rectangular cross section bus rigidity is higher, surface area is bigger; Strong and the good heat dissipation effect to the burst accident resistance; It builds that the effective contact area of device is big, contact resistance and caloric value are little, has improved the overall technology performance of switchgear.

Embodiment
For making the present invention more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
Fig. 1 is a kind of switchgear assembly provided by the invention " H " type cross section bus sketch map; Described a kind of switchgear assembly " H " type cross section busbar cross-section is " H " type; Two U-lags 3 lay respectively on two leptoprosopy of bus, and contact plane 5 is smooth wide.
In conjunction with Fig. 2-Fig. 5; During assembling, the correspondence position on the contact plane 5 of two " H " type cross section buses is all stamped installing hole 4 earlier, generally makes a call to the installing hole 4 that 4 quadrates are arranged; Two contact planes 5 on " H " type cross section bus 1 are close to; Alignment bus installing hole 4, with 4 fastening bolts 2 pass installing hole 4 assemble, fastening, accomplish whole assembling process.Fastening bolt 2 is a working standard spare, is furnished with nut, bullet pad and plain cushion.
