Abstract
The utility model relates to a fuse device for a contact breaker for a power distribution network, which comprises a base 1 which relates to an isolator whose both ends are fixedly connected with a fixed contact 3, both ends of a tool arm 5 which are made of isolation material are provided with a conductor 6, one end of the tool arm is hinged with the fixed contact 3, and the other end of the tool arm is embedded in the gap groove 4 of the fixed contact 3; a fuse 7 is connected between two conductors 6; the fuse 7 is connected with the fixed contact 3 which is adjacent to the hinged end of the tool arm 5 through a flexible conducting wire.
Description
The utility model is relevant with distribution transformer low-pressure side disconnecting link safeties in the distribution network.
The disconnecting link safeties are used for breaking in distribution network and close power supply and carry out overcurrent protection.Traditional disconnecting link safeties are installed porcelain insulator on the flute profile copper pedestal, install and fix contact on porcelain insulator, copper tool sheet and safety plate.Assembling is complicated, and bulky elements is many, and the low pressure porcelain insulator very easily damages, the cost height, and the life-span is short, safeguards inconvenience.
The purpose of this utility model provides a kind of simple in structure, light, and cost is low, installation, easy to maintenance, the disconnecting link safeties of safety durable.
The utility model is achieved in that
1 of base is as insulation board, and each is connected its two ends with a fixed contact 3.Insulation tool arm 5 two ends are that conductor 6, one ends and fixed contact 3 are hinged, and the other end can be entrenched in the clearance groove 4 of another fixed contact 3, has fuse 7 to connect between two conductors 6.The be hinged adjacent fixed contact of end 3 of fuse 7 and tool arm is connected by flexible conductor.
Base 1 of the present utility model can be connected with insulated leg 2, and insulated leg 2 is connected with fixed contact 3.Fixed contact 3 is made up of two copper sheets, and groove 4 is arranged therebetween.The conductor 6 at tool arm 5 two ends is for containing the copper coin of end, and tool arm 5 chimeric end conductors 6 are knife-edge.Have double threaded screw 8 to pass conductor 6 and tool arm 5, fuse 7 is fixed on the screw rod 8 by nut 9.
Base 1, bearing 2, tool arm 5 can be shaped by fiberglass and make.
The copper coin and the fuse of the utility model fixing conduction on the fiberglass tool arm have energising, break and close, insure triple functions.Simple in structure, in light weight, cost is low, and the life-span is long, and installation and operation is easy to maintenance, both safety, and economy is good again.
Following is accompanying drawing of the present utility model:
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the A-A partial sectional view of Fig. 1.
Following is embodiment of the present utility model:
Be connected by bolt 10 between fiberglass base 1 and the fiberglass bearing 2.Be connected by bolt 10 between fixed contact 3 that copper sheet is formed and the bearing 2.Fiberglass tool arm 5 is a chi shape, and the conductor 6 that its two ends are surrounded by conductor 6, one ends is knife-edge, and with groove 4 chimeric contacts of fixed contact 3, the other end and fixed contact 3 are hinged by hinge 11.Two ends conductor and tool arm 5 are by double threaded screw 8, and nut 9 connects.Fuse 7 is connected on the double threaded screw 8.Be hinged and be connected by annealed copper wire 12 between the copper coin of screw rod 8 and fixed contact 3 on the end conductor 6.
