Description
Technical field
The present invention relates to a kind of fuse, particularly a kind of high voltage drop-out type fuse cutout with copper-aluminium transition equipment cable clamp.
Background technology
Fuse is after exceeding setting a period of time according to electric current, makes Melt molten, thus circuit is disconnected with the heat that himself produces; Use a kind of current protector that this principle is made.Fuse is widely used in high and low voltage electric distribution system and control system and power consumption equipment, as the protector of short circuit and overcurrent, is apply one of the most general protection device.Common fuse has plug-in fuse, screw type fuse, protected cut-out, fuse switch and self-healing fuse etc.
Wherein fuse switch refers to due to fuse failure, and the upper lower moving contact of cartridge fuse loses the fastening force of fuse, cartridge fuse is fallen rapidly under the effect of self gravitation, thus circuit is disconnected, a kind of fuse of excision faulty section circuit or faulty equipment.Fuse switch can breaking current rapidly, has obvious cut-off point, can protect the life security of fuse lower end power consumption equipment and personnel.But, the terminals of the high voltage drop-out type fuse cutout upper end in existing electric power system directly and connection, because many equipment outlet terminals are copper coin, aluminum equipment wire clamp is connected with copper tip, there is the electric transition of metal that two kinds of potential differences are different, the generation that is in operation can produce device clamp corruption, needs independent installation fee expenses of labour when high voltage drop-out type fuse cutout upper end installs wire clamp of copper-aluminum apparatus.
Summary of the invention
The object of this invention is to provide a kind of high voltage drop-out type fuse cutout with copper-aluminium transition equipment cable clamp, on fuse, terminals copper-aluminium transition equipment cable clamp is carried by fuse, ensure that contact, is fixed well, avoids device clamp corruption, the flow process that simplifies the operation, saved manpower.
To achieve these goals, the present invention is by the following technical solutions:
A kind of high voltage drop-out type fuse cutout with copper-aluminium transition equipment cable clamp, comprise insulation column and cartridge fuse, the top of described insulation column is provided with mounting bracket, upper mounting bracket is provided with terminals, upper terminals are connected with copper-aluminium transition equipment cable clamp, and described copper-aluminium transition equipment cable clamp is provided with binding post; The middle part of insulation column is provided with installing ring; The bottom of insulation column is provided with lower mounting bracket, and lower mounting bracket is provided with lower terminals, corresponding to upper and lower fixed contact on described upper terminals and lower terminals; The upper/lower terminal correspondence of described cartridge fuse is provided with upper and lower moving contact, be connected through fuse between upper and lower moving contact, cartridge fuse is arranged between the upper terminals of insulation column and lower terminals by upper and lower moving contact, and the upper and lower fixed contact of upper terminals and lower terminals contacts with the upper and lower moving contact of cartridge fuse respectively, and described cartridge fuse is also provided with draw ring.
Pass through technique scheme, the utility model installs copper-aluminium transition equipment cable clamp on the upper terminals of fuse, device clamp is merged or is engaged in upper terminals, both the electric transition of metal that two kinds of potential differences are different had been avoided, be in operation the device clamp corruption produced, in turn ensure that contact, be fixed well, eliminate the hardship coming and going processing, also save processing charges.
Further, upper mounting bracket described in the utility model is provided with the drag hook for load.
Further, copper-aluminium transition equipment cable clamp described in the utility model and upper terminals are connected through bolt.
Further, weld between copper-aluminium transition equipment cable clamp described in the utility model with upper terminals.
The beneficial effects of the utility model are: 1. the utility model arranges copper-aluminium transition equipment cable clamp by coordinating the method installing or merge welding on the upper terminals of fuse, high-voltage line is directly connected by copper-aluminium transition equipment cable clamp, it is simple, convenient to use, compact need not carry out processing in advance, reliability is strong, substantially reduce the operating time, improves operating efficiency.2. upper installation end cooperation of the present utility model is installed or merges soldering copper aluminium transition equipment cable clamp, and roll off the production line wire diameter change not quite because 10kV circuit becomes platform, device therefor wire clamp can meet the wire diameter of different model, and fixation is reliable, installs simple.
