Description
Technical field
The utility model relates to circuit protection device, and being specifically related to one can charged for replacement overhead transmission line overvoltage protection device.
Background technology
A common overhead transmission line overvoltage protection device, its lower moving contact is directly fixed on the bottom of cartridge fuse, and its lower moving contact and lower fixed contact are block, and non-resilient connection, easily causes loose contact therebetween; In addition, this overvoltage protector does not arrange fault disconnector, is unfavorable for circuit maintainer Timeliness coverage and pumping-out line fault.
Utility model content
The utility model discloses a kind of overvoltage protection device of novel overhead transmission line, be intended to the defect improved existing for the said goods.
The technical solution of the utility model is as follows:
One can charged for replacement overhead transmission line overvoltage protection device, comprises insulator, high-voltage discharging rod and fuse; Described high-voltage discharging rod earth connection; Described fuse is located in a cartridge fuse, its top is touched with the upper static contact be located on described insulator mutually by the upper moving contact be located on described cartridge fuse, its bottom is touched with the lower fixed contact be located on described insulator mutually by the lower moving contact be located on described cartridge fuse, thus turning circuit; Described lower moving contact is an independent conducting block, is bolted on the hoop head place of a shroud ring, and the cranse of described shroud ring wraps up and is fixed on its bottom of described cartridge fuse; Described cartridge fuse pipe shaft on the downside of described shroud ring is also provided with a fault disconnector, and the bottom of described fuse is fixed on described lower moving contact through after this fault disconnector; Described lower fixed contact is an independent electroconductive elastic sheet, is arranged at and drags, and drags the one end being fixed on a plate under described, and the other end of described connecting plate is bolted on the bottom of described insulator; Drag under described and be provided with storage tank, described lower moving contact is arranged in this storage tank; Described lower moving contact is provided with rotating shaft, its rotating shaft both sides be located at described under drag set by both sides axial trough in.
Compared to overvoltage protector before, can Elastic Contact between lower moving contact of the present utility model and lower fixed contact, improve stability during conduction, by arranging fault disconnector, being conducive to maintainer's Timeliness coverage and pumping-out line fault.
Accompanying drawing explanation
Fig. 1 is the general structure schematic diagram of the utility model embodiment.
Be labeled as in figure: 1, insulator, 2, fuse, 3, cartridge fuse, 4, upper moving contact, 5, upper static contact, 6, lower moving contact, 7, lower fixed contact, 8, shroud ring, 9, heat explosion type fault disconnector, 10, under drag, 11, connecting plate, 12, high-voltage discharging rod.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described.
With reference to Fig. 1:
One can charged for replacement overhead transmission line overvoltage protection device, comprises insulator 1, high-voltage discharging rod 12 and fuse 2;
High-voltage discharging rod 12 earth connection;
Fuse 2 is located in a cartridge fuse 3, its top is touched with upper static contact 5 phase be located on insulator 1 by the upper moving contact 4 be located on cartridge fuse 3, its bottom is touched with lower fixed contact 7 phase be located on insulator 1 by the lower moving contact 6 be located on cartridge fuse 3, thus turning circuit;
Lower moving contact 6 is an independent conducting block, is bolted on the hoop head place of a shroud ring 8, and the cranse of shroud ring 9 wraps up and is fixed on its bottom of cartridge fuse 3; Cartridge fuse 3 pipe shaft on the downside of shroud ring 8 is also provided with a heat explosion type fault disconnector 9, the bottom of fuse 2 is fixed on lower moving contact 6 through after this heat explosion type fault disconnector 9;
Lower fixed contact 7 is an independent electroconductive elastic sheet, is arranged at and drags on 10, under drag 10 to be fixed on a plate 11 one end, the other end of connecting plate 11 is bolted on the bottom of insulator 1; Under drag 10 to be provided with storage tank, lower moving contact 6 is arranged in this storage tank; Lower moving contact 6 is provided with rotating shaft 6a, and its rotating shaft 6a is located at down both sides in the axial trough 10a that drags set by 10 both sides.
By swaying, lower moving contact 6 can Elastic Contact or be separated completely with lower fixed contact 7, thus reaches the effect of conducting or buffer circuit.
Heat explosion type fault disconnector 9 utilizes short circuit current to produce arcing, ignites the thermal explosion element of its inside to reach the object of disengaging, thus plays failure identification effect, reminds maintainer to repair in time.
