Abstract
A fuse with a grounding device comprises an insulating pillar and a fuse tube. The upper part of the insulating pillar is equipped with an upper mounting bracket, and the upper mounting bracket is equipped with an upper wiring terminal. The lower part of the insulating pillar is equipped with a lower mounting bracket, and the lower mounting bracket is equipped with a lower wiring terminal. Upper and lower static contacts are correspondingly attached to the upper and lower wiring terminals. The two ends of the fuse tube are correspondingly provided with upper and lower moving contacts. The fuse tube is mounted between the upper wiring terminal and the lower wiring terminal of the insulating pillar through the upper and lower moving contacts. The lower wiring terminal is electrically connected with the upper end of an insulated extension conductor, and the lower end of the insulated extension conductor is equipped with an equipment clamp. A grounding hanging ring is arranged on the insulated extension conductor. A pull ring is arranged on the fuse tube. The invention aims to provide a fuse with a grounding device. The problem that a fuse without a grounding hanging ring needs to be temporarily equipped with a grounding hanging ring is solved, the personal safety can be effectively guaranteed, and the work efficiency can be improved.
Description
Technical field
The present invention relates to a kind of fuse, be specifically related to a kind of fuse carrying earthing device.
Background technology
Fuse switch is rapid breaking current, has obvious cut-off point, cut-offs proterctive equipment with what protect fuse lower end power consumption equipment and human life's safety.When there are the needs of fault, test, installation and adjustment fuse switch lower end, pull open fuse, can allow after electrical verification ground connection to enter working site.Earthing device is an important technique measure ensureing the person and device security, at ground connection link place installing earth connection, guarantees that equipment is not with voltage, to ensure that maintainer carries out work under no-voltage environment.
Existing ground connection link needs some positions on in-site installation to transformer downlead, and particular location is not temporarily sought unity of standard.Because transformer downlead mostly is insulated conductor, also will peel off insulating barrier, ground connection link is stuck on transformer downlead, installs after fixing and also will carry out wire insulation recovery, not only insecure, but also time-consuming.Power department as service industry earnestly implements electric service ten promise, accomplishes that supply line's equipment carefully stops, to stop less, and one stops multiplex, reduces the impact of user power utilization as far as possible or the loss caused that has a power failure is dropped to minimum." time, efficiency " is in face of the benefit pursued of the mankind, just requires that we design " high voltage drop-out type fuse cutout is from link with ground ", stops potential safety hazard, reduces interruption duration, increase work efficiency.
Summary of the invention
The object of this invention is to provide a kind of fuse carrying earthing device, solve the fuse not having ground connection link, need to install ground connection link phenomenon additional temporarily, can effective guarantee personal safety, increase work efficiency.
The present invention is by the following technical solutions in order to achieve the above object:
Carry a fuse for earthing device, comprise insulation column and cartridge fuse, the top of described insulation column is provided with mounting bracket, and upper mounting bracket is provided with terminals; The middle part of insulation column is provided with middle 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 and lower terminals; The two ends 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, described lower link is electrically connected with the upper end of insulation extension wire, the lower end of insulation extension wire is provided with device clamp, insulation extension wire is provided with ground connection link, and described cartridge fuse is also provided with draw ring.
Pass through technique scheme, under fuse of the present invention, link is provided with one section of insulation extension wire, ground connection link is directly arranged on insulation extension wire, solve the fuse not having ground connection link, need to install ground loop phenomenon additional temporarily, the present invention is fixedly connected with reliably, and standard is unified, installs and does not need to increase workload.
Further, ground connection link of the present invention is located at distance insulation 40cm place, extension wire upper end.
Further, upper mounting bracket of the present invention is provided with the drag hook for load.
Further, upper terminals of the present invention are provided with copper-aluminium transition equipment cable clamp.
Further, device clamp of the present invention is copper-aluminium transition equipment cable clamp.
Beneficial effect of the present invention is: with ground connection link on fuse of the present invention, ground connection link and miscellaneous part compact overall structure, compact, easy for installation; When using the present invention to complete ground connection operation, fixing after the insulation of transformer downlead need not be cut open, but directly ground wire hitching on ground loop, can either ensure that safety measure puts in place and make, and with simply, conveniently, substantially reduce the operating time.
