Description

A kind of drawout cubicle vertical bus bar

Technical field

The utility model relates to drawout cubicle, especially a kind of drawout cubicle vertical bus bar.

Background technique

Conventional low-voltage drawer cabinet vertical bus bar has L shape busbar and C-shaped busbar, common L shape busbar and C shape busbar point It does not have the disadvantage that:

(1) L-type vertical bus bar current-carrying capacity is smaller in drawout cubicle, and usual maximum can only accomplish 1250A, and thermal stability and dynamic Stability is poorer than c-type vertical bus.

(2) L-type vertical bus bar punches after measurement and positioning on L-type copper bar again with needs when branch's busbar or cable connection, Heavy workload.

(3) for c-type vertical bus bar due to structure problem, usually only a kind of current class 1600A is next for small current system It says and wastes very much, and c-type vertical bus bar cannot be used cooperatively with Y shape drawer plug.

CN205141578U discloses a kind of novel busbar, and busbar cross section structure is two c-type structure bottoms to bottom integration Molding, can only be applicable in spring copper sheet plug-in module, it is impossible to be used in Y type Y type drawer plug cabinet type.

Small for L-type vertical bus bar current-carrying capacity, current class only has the problem of 1250A, and CN 201623375U is disclosed A kind of adjustable, combined type vertical bus is a kind of adjustable, combined type vertical bus, and bus bar is in L shape, and one end is mounted on insulation In supporting element, the other end is used as conductive static contact, has zero to arrange to multiple rectangular bus bars behind L shape bus bar, passes through increase The quantity of rectangle busbar, magnitude of current maximum also can only achieve 1900A, and L-type busbar and rectangle busbar are relatively independent, and part is more, A combination thereof is inconvenient for operation, and occupied space is big, and stability is poor.

Summary of the invention

The purpose of this utility model is that: solve that problem above provides a kind of dynamic stability and thermal stability is good, installation connects Connect the high a kind of novel busbar of convenience, current-carrying capacity.

Busbar has c-type emissions groove mouth, is the bottom edge of busbar with notch relative edge, a side of notch with bottom intersection Continue to extend outwardly along side directions, constitutes the long side of busbar.In the case where the width of vertical bus bar is constant, pass through adjusting Vertical bus bar notch two sides edge lengths and bottom edge thickness, to adjust vertical bus bar current flux, current flux is reached as high as 2000A。

Be arranged vertical bus bar notch length be 11mm, a length of 30mm in busbar bottom edge, the long side of vertical bus bar with it is another The length ratio of side be 10~13:5~8, copper bar with a thickness of 5~8.

Further, a length of 50~65mm of the long side of vertical bus bar, other side side length are 25~40mm.

As a length of 50mm of the long side of vertical bus bar, a length of 25mm of short side, copper bar cuts with a thickness of 5mm, vertical bus bar Area is 520mm², current-carrying capacity 1250A；

As a length of 65mm of the long side of vertical bus bar, short side edge lengths are 30mm, and when with a thickness of 5mm, vertical bus bar is cut Area 620mm², current-carrying capacity 1600A；

When the long side length of vertical bus bar is 65mm, long side opposite end length is the thickness of 40mm, busbar bottom edge and notch For 8mm, busbar two sides with a thickness of 6mm, the sectional area of vertical bus bar is 862mm², current-carrying capacity may be up to 2000A.

I.e. by adjusting vertical bus bar notch two sides edge lengths and bottom edge thickness, the electric current that can reach 1250~2000A is logical Amount.

Beneficial effect

Busbar has c-type emissions groove mouth, is the bottom edge of busbar with notch relative edge, a side of notch with bottom intersection Continue to extend outwardly along side directions, constitutes the long side of busbar.In the case that the width of vertical bus bar is constant, hung down by adjusting Straight two side length of busbar and bottom edge thickness, adjustable vertical bus bar current flux are up to 2000A.

Novel busbar has C-shaped channel mouth, and non-porous connection can be realized by bolt, structurally internal stress is not destroyed, does not influence slot Mouth dimensional tolerance；Busbar material material thickness reduces, but surface area increases, and improves heat dissipation performance and increases the current-carrying capacity of busbar； It is abnormally-structured, improve mechanical strength.

Novel busbar reduces the dosage of copper and the weight of cabinet body compared with the vertical bus bar of same current class, and increases The strong thermostabilization and dynamic stability of busbar.

New vertical busbar as L-type busbar, has L-type busbar electric current flexible and changeable with drawer plug kit form Performance, and Y type drawer plug cabinet type is suitble to use, it is suitable for current most domestic low voltage cabinet drawer cabinet type.

Specific embodiment

With reference to the accompanying drawings and detailed description, the drawout cubicle new vertical busbar of the utility model is done furtherly It is bright.

1, the contour structures and current flux of drawout cubicle new vertical busbar

As shown in Figure 1, the vertical bus bar of the utility model has c-type emissions groove mouth, it is the bottom edge of busbar with notch relative edge, A side of notch is continuing to extend outwardly with bottom intersection along side directions, constitutes the long side of busbar.It is vertically female like L-type The combination of row and c-type vertical bus bar.By changing the length of the utility model vertical bus bar side A, B and the thickness of bottom edge E, adjust The current flux for saving vertical bus bar under conventional working condition, surveys maximum current flux up to 2000A.

(1) two sides A, B length of new vertical busbar is respectively that 50mm, 25mm, copper bar are a length of with a thickness of 5mm, bottom surface The length of the open C of 30mm, notch is 11mm, then the sectional area size of new vertical busbar is (50+25+20+20-11) × 5 =520mm², current-carrying capacity 1250A.

(2) two sides A, B length of new vertical busbar is respectively that 65mm, 30mm, copper bar are a length of with a thickness of 5mm, bottom surface 30mm, notch C length are 11mm, then the sectional area size of new vertical busbar is (65+30+20+20-11) × 5= 620mm², current-carrying capacity 1600A.

(3) two sides A, B length of new vertical busbar is respectively that 60mm, 30mm, copper bar are long with a thickness of 5.5mm, bottom surface It is 11mm for 30mm, notch C length, then the sectional area size of new vertical busbar is (60+30+20+20-11) × 5.5= 654.5mm², current-carrying capacity 1636A.

(4) two sides A, B length of new vertical busbar is respectively 65mm, 40mm, copper bar with a thickness of 5mm, bottom surface D long Be 11 for 30mm, notch C length, bottom edge E and notch with a thickness of 8mm, then the sectional area size of new vertical busbar is (65+ 40) × 6+ (20+20-11) × 8=862mm², current-carrying capacity is up to 2000A or more.

Wherein (5 × 2) i.e. 20=30- contain the thickness number of two sides in the bottom edge length value 30mm of vertical bus bar Value, because side is with a thickness of 5mm, then two sides with a thickness of 10mm, therefore need to reduce, in order to avoid calculate repetition.

2, drawout cubicle new vertical busbar is connect with drawer plug

For such vertical bus bar with drawer plug kit form as L-type bus, L-type busbar is not only used as current-carrying, but also conduct The primary conductive static contact of functional unit, such as Fig. 2, vertical bus bar H is fixed on bus clip F by bolt I, compact-sized, Conducive to device miniaturization, and the one end vertical bus bar H extends part out outward, can be suitable for current state with drawer Y type Plug contact Interior major part low voltage cabinet drawer cabinet type.

3, the non-porous installation of drawout cubicle new vertical busbar and connection

Such as Fig. 3, the utility model vertical bus bar H is connect by bolt I with vertical bus bar bus clip F, can also directly with Connection row J is connected by bolt I.Three matched with vertical bus bar or four mounting grooves are provided on bus clip F, it is vertical female Notch on row blocks nut, and wherein bolt is T-bolt, and nut is rectangular, and nut width is not more than busbar width of rebate, long Degree is greater than width of rebate, and to facilitate insertion T-bolt, non-porous installation and connection may be implemented, install very convenient.
