Abstract
Connecting device of tubular busbar branch relates to electrical equipment annex technical field, especially belongs to a connecting device of tubular busbar branch. Have connector (2), the connector is the three way type structure, every link of connector disposes C type staple bolt (3), and the internal diameter of connector is greater than tubular busbar's external diameter and cup joints to be installed on tubular busbar, and is fixed through C type staple bolt. Simple structure, compactness, the utility model discloses adopt the same material with tubular busbar, and the internal diameter is greater than tubular busbar's external diameter, makes it can closely firmly cup joint and the face bonding is even, face contact nature is good with tubular busbar under the exogenic action, have the reliable positive effect of practicality.
Description
Technical field
The utility model is related to electrical equipment attachment technique field, especially belongs to a kind of tube type bus branch connection dress
Put.
Background technology
Tube type bus are mainly used in China's power construction engineering between grid power transmission wire and substation transformer
Make excessively stream in wire jumper in conductor connection, transmission line of electricity, the connection conductor in power equipment and heavy DC deicing device
Conductor, is the brand-new conductor of the traditional rectangle of substitution, flute profile, rod bus and flexible circuit conductor, is key in electric power power transmission and transformation system
Equipment（Material）One of, the safe and reliable operation to power transmission and transformation system and power equipment plays vital effect.
The key factor for determining the quality good or not of tube type bus is conductor, insulating materials and bus interconnection technique.Cast is female
The technical matters level of line connection, has strong influence for the service life and regular maintenance of bus.At this stage, with
The quick steady-state growth of national economy, society's electricity consumption amount linearly rises so that the capacity of transforming plant main transformer is constantly increased, main
The rated current for becoming low-pressure line-outgoing side also increases therewith.But because switch cubicle is different to the current requirements of tube type bus, this is just
Branch design is carried out to tube type bus, i.e., main transformer output current be shunted.How tube type bus branch components are carried out
The reliable fastening tube type bus structure design that is connected to become is had to the problem for facing.Current tube type bus branch connected mode,
Including following several：
1st, T-shaped connection：Simple mechanical structure, is sheerly manual system not including electronic control system；
2nd, interpolation type threeway：Threeway it is each to.
But there is installation difficulty in existing tube type bus branch connecting structure, and be difficult to ensure that face combine it is uniform,
The refined grade of the good profile of face contact requires.
The content of the invention
It is to provide a kind of tube type bus branch attachment means that the purpose of this utility model is, to reach simple structure, set
Meter is reasonable, easy for installation, firm, and face combination is uniform, face contact is good and electric conductivity is good, tensile strength is high, profile is refined
Purpose.
Tube type bus branch provided by the utility model attachment means, it is characterised in that with connector, connector is
Three way type structure, each connection end of the connector is configured with c-type anchor ear, connector use with tube type bus identical material,
Wherein, the internal diameter of connector is more than the external diameter of tube type bus and socket is installed on tube type bus, is fixed by c-type anchor ear.
Further, the c-type anchor ear realizes that the closure of breach is welded by stainless steel electrode.
Further, the notch diameter of the c-type anchor ear is set in the range of 10mm-15mm.
Further, each connection end of the connector is provided with 2 c-type anchor ears.
Tube type bus branch provided by the utility model attachment means, simple structure, compact, the utility model and cast
Bus uses identical material, and internal diameter makes it under external force can be tight with tube type bus more than the external diameter of tube type bus
It is good that close firm socket and face combine uniform, face contact, with practical reliable good effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Tube type bus branch provided by the utility model attachment means, including three way type connector 2, the connector
Each connection end be provided with 2 c-type anchor ears 3, connector use with the identical material of tube type bus 1, the internal diameter of connector is slightly
More than tube type bus external diameter and socket be installed on tube type bus, fixed by c-type anchor ear.Wherein, the socket of tube type bus
Contact jaw and the connector insertion connection end of hem type threeway, set is pressed using hydraulic machinery under 120~250 tons of pressure
Connect so that tube type bus connect together with connector close and firm and face combined uniformly, face contact it is good, while having conduction
Excellent performance, tensile strength are high, profile is refined and low cost advantage, and the utility model is also widely applied to power transmission process
Connection between tube type bus and between tube type bus and miscellaneous equipment.
Additionally, being the close and firm for strengthening being connected, the notch diameter of the c-type anchor ear is set to 10mm-15mm
In the range of, meanwhile, by stainless steel electrode, realize the closure welding of c-type anchor ear breach.
Claims (4)
1. in a kind of tube type bus branch attachment means, it is characterised in that with connector（2）, connector is three way type structure,
Each connection end of the connector is configured with c-type anchor ear（3）, the internal diameter of connector more than tube type bus external diameter and be socketed installation
In on tube type bus, fixed by c-type anchor ear.
2. tube type bus branch according to claim 1 attachment means, are further characterized in that, the c-type anchor ear is not by
Rust steel electrode realizes the closure welding of breach.
3. tube type bus branch according to claim 2 attachment means, are further characterized in that, the breach of the c-type anchor ear
Diameter is set in the range of 10mm-15mm.
4. tube type bus branch according to claim 3 attachment means, are further characterized in that, each company of the connector
Connect end and be provided with 2 c-type anchor ears.
