Description

Novel current collection overhead line structures
Technical field
The utility model relates to a kind of current collection overhead line structures, especially a kind of novel current collection overhead line structures.
Background technique
The electric energy that wind power plant inner blower generates needs access set electric line after box type transformer boosts, and after through current collection Route is sent into substation, to realize the online transmission of electric energy.
Box type transformer is connected directly with collection electric line in previous wind power plant, and in operational process, separate unit box type transformer goes out When existing failure is overhauled, the whole current collection line outage for connecting the change of this case is handled, this is caused to collect in electric line The electric energy that the blower of other normal operations generates can not convey, and cause great energy waste.In addition, short circuit occurs for collection electric line Or when by being struck by lightning, the instantaneous extreme currents of generation can damage the electrical equipment in box type transformer.
Summary of the invention
Aiming at the shortcomings existing in the above problems, the utility model provides a kind of convenient for box type transformer and collection electric wire Road disconnects maintenance, and prevents transient high-current from damaging to box type transformer, protects the new of box transformer station high-voltage side bus safety Type current collection overhead line structures.
To achieve the above object, the utility model provides a kind of novel current collection overhead line structures, including shaft (6), described Multiple column support type insulators (1) and lightning rod (3), multiple column support type insulators (1), the lightning rod are equipped on shaft (6) (3) by insulated conductor (5) respectively with the collection electric line (7) being located above the shaft (6) and positioned at the shaft (6) The box type transformer (8) of side is electrically connected, and is also equipped in the side of the shaft (6) and is electrically connected with the insulated conductor (5) Drop out fuse (4).
Above-mentioned novel current collection overhead line structures, wherein the top of the insulated conductor (5) by T connect fitting (2) with it is described Collect electric line (7) electrical connection.
Above-mentioned novel current collection overhead line structures, wherein between the column support type insulator (1) and the insulated conductor (5) It is reserved with spacing, the electrical distance that the spacing is formed between the column support type insulator (1) and the insulated conductor (5).
Above-mentioned novel current collection overhead line structures, wherein the lightning rod (3) is located at the cross-arm of the shaft (6), and Fitting (2) is connect by conducting wire and T to be electrically connected with the insulated conductor (5).
Compared with prior art, the utility model has the advantage that
By installing fuse switch additional on current collection overhead line structures, disconnects and examining convenient for box type transformer and collection electric line It repairs, and prevents transient high-current from damaging to box type transformer, protect the operational safety of box type transformer.
Detailed description of the invention
Fig. 1 is the structural block diagram of the utility model.
Main appended drawing reference is described as follows:
1- pillar insulator;2-T connects fitting;3- arrester;4- drop out fuse;5- insulated conductor;6- shaft;7- current collection Route;8- box type transformer
Specific embodiment
As shown in Figure 1, the utility model provides a kind of novel current collection overhead line structures, including shaft 6, assemble on shaft 6 Have multiple column support type insulators 1 and a lightning rod 3, multiple column support type insulators 1, lightning rod 3 by insulated conductor 5 respectively be located at The collection electric line 7 of 6 top of shaft and the box type transformer 8 positioned at 6 side of shaft are electrically connected, and are also assembled in the side of shaft 6 There is the drop out fuse 4 being electrically connected with insulated conductor 5.
Wherein, the top of insulated conductor 5 connects fitting 2 by T and is electrically connected with collection electric line 7.
Wherein, spacing is reserved between column support type insulator 1 and insulated conductor 5, spacing is column support type insulator 1 and insulation The electrical distance formed between conducting wire 5.
Wherein, lightning rod 3 is located at the cross-arm of shaft 6, and connects fitting 2 by conducting wire and T and be electrically connected with insulated conductor 5 It connects.
The insulated conductor 5 attracted by box type transformer high-voltage side, the column support type insulator by being mounted on shaft lower part are fixed In shaft, drop out fuse 4 is connected up along shaft, is continued up after connection drop out fuse and leads to current collection line conductor, from And realize circuit communication.
By the arrester 3 being mounted at shaft cross-arm, lightning protection can be carried out to route.
After completing above-mentioned installation, when needing to overhaul box type transformer, fuse switch is pulled open manually The connection with collection electric line is disconnected, and will not influence the electric energy transmission of other blowers in this collection electric line.
Due to, equipped with the fuse for preventing overload current, short circuit occurring in electric line or by thunder when collecting in fuse switch When hitting, instantaneous super-high-current can disconnect automatically the fuse failure in fuse switch, drop out fuse, to realize to case The protection of electrical equipment in formula transformer.
The above is only the preferred embodiment of the present invention, is merely illustrative for invention, rather than limits Property.Those skilled in the art understand that in the spirit and scope defined by invention claim many changes can be carried out to it, It modifies or even equivalent, but all will fall within the protection scope of the utility model.
