Abstract
The utility model relates to a tension and drop resistant fuse, which is the improvement to the prior drop-out type fuse structure. The utility model provides a drop-out type fuse which has the advantages of material saving, increased movable space on a pole-tower, less construction difficulty and convenient operation. The tension and drop resistant fuse comprises an insulator and a fuse tube; and the essential of the structure is that the insulator and the fuse tube are in parallel with a lead.
Description
Technical field:
The utility model relates to the improvement of fuse switch structure.
Background technology:
Along with fast development of national economy, the continuous growth to electricity needs causes the minimizing in electric line corridor.Form present joint use twoly return, the increase, the particularly T on many telegrams in reply line of force road on many telegrams in reply line of force road connect the shaft tower that branched line is installed fuse switch, installs because fuse switch is perpendicular, it is big to take vertical space.The minimizing in space on the shaft tower.The activity space of maintenance workmen on shaft tower is little, difficulty of construction big, inconvenient operation.
The utility model content:
The utility model just provides and a kind ofly saves material, increases activity space on the shaft tower, reduces difficulty of construction, easy to operate fuse switch.
The utility model adopts following technical scheme: the utility model comprises insulator, cartridge fuse, and its structural feature is that insulator and cartridge fuse and lead be arranged in parallel.
The utility model beneficial effect:
1, convenient construction maintains easily:
Because the utility model insulator and cartridge fuse and lead be arranged in parallel; So under the situation of safety that does not influence equipment and mechanical performance, the perpendicular installation of minimizing fuse switch takies the space on the shaft tower, increases activity space on the shaft tower, convenient construction, operation maintenance is also very convenient;
2, opening velocity is faster, and the electric arc ability of going out is stronger:
Because the utility model insulator and cartridge fuse and lead be arranged in parallel, during operation, the anglec of rotation was about 90 degree when cartridge fuse of the present utility model fell, the anglec of rotation the when anglec of rotation is far smaller than perpendicular installation the (the cartridge fuse anglec of rotation of fuse switch is about 180 degree during perpendicular the installation); Perpendicular when the fuse switch fuse being installed just having fused, be by the elastic force of spring separately after, finish separating brake by the action of gravity free fall again; And the utility model fuse has been when just having fused, and the elastic force of spring and gravity act on simultaneously finishes separating brake.Fuse switch opening velocity when therefore the utility model is than perpendicular the installation is faster, and the electric arc ability of going out is stronger;
3, economical with materials, be beneficial to and popularize:
The utility model is easy for installation when power line construction, and when wire erection was finished, the utility model is installation also, does not need to install in addition the fuse switch and the fixing cross-arm of fuse switch; Save the cross-arm material, saved the man-hour that cross-arm, fuse switch are installed.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
The utility model comprises that insulator 4, cartridge fuse 1, insulator 4 and cartridge fuse 1 be arranged in parallel with lead 2.Can be provided with binding post 7 on the described insulator 4, can upper and lower setting be at least two, four binding posts 7 are preferably arranged,, make construction and installation more convenient to satisfy different wiring.
The utility model contact 3 is fixed on the bulb side 5 of insulator 4, and contact 6 is fixed on the middle part of insulator 4.
In practical operation, being installed on the 35kV insulator of 10kV fuse switch, insulator as the power circuit insulation against ground time again as the fracture of fuse switch and insulator over the ground; Save material, economize on resources.
Insulator described in the utility model can be strain insulator.
Claims (4)
1, a kind of strain insulator fuse switch comprises insulator (4), cartridge fuse (1), it is characterized in that insulator (4) and cartridge fuse (1) be arranged in parallel with lead (2).
2, a kind of strain insulator fuse switch according to claim 1 is characterized in that described insulator (4) is provided with binding post (7).
3, a kind of strain insulator fuse switch according to claim 2 is characterized in that the upper and lower setting of binding post (7) is at least two.
