Abstract
The utility model discloses a voltage transformer with a fuse. The voltage transformer is characterized in that a fixed rubber bushing, which is shaped like a round tube, is arranged in an inner tube in a clearance fit manner, the fuse is arranged in the fixed rubber bushing, and is matched with the inner wall of the fixed rubber bushing, and the fuse is fixed in the inner tube by the fixed rubber bushing. Fuses of different specifications can be stably mounted in the voltage transformer, the application range of the voltage transformer is broadened, the applicability of the voltage transformer is enhanced, and the voltage transformer is convenient to mount.
Description
Technical field
The utility model relates to a kind of voltage transformer, and more particularly, it relates to a kind of voltage transformer with fuse.
Background technology
Voltage transformer is as the important devices of various measurements, metering, instrument and relaying protection, can make instrument, relaying protection system and operations staff and high-pressure system isolation, Electrical Safety and avoid bringing threat to operations staff.Fuse is to cut off the requisite protective device of device line fault, the connection of fuse and the reliability direct relation switchgear of work and the security of operation of circuit in voltage transformer.
At present, a kind of voltage transformer with fuse on market, comprises current transformer body, coil, iron core, main insulation material, insulating sleeve, and the top of current transformer body forms binding post, binding post inside in current transformer body offers inner tube, is placed with fuse and spring in inner tube the inside.Although this voltage transformer with fuse solves the external problem of fuse, but the fuse of inner tube the inside easily can rock, cause fuse and coil, spring contact bad, inner tube can only be placed a kind of fuse of specification simultaneously, and the voltage transformer being not easy to fuse is installed.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of voltage transformer with fuse, has the advantages that fuse stable connection is reliable, be convenient to installation.
For achieving the above object, the utility model provides following technical scheme: include current transformer body, the top of described current transformer body forms binding post, binding post inside in current transformer body offers inner tube, coil, be placed with fuse and spring in inner tube the inside, described inner tube the inside is provided with fixing rubber bushing, described fixing rubber bushing is tubular, and can multiple same outer diameter for subsequent use, the fixing rubber bushing of different inner diameters size, described fixing rubber bushing and inner tube are matched in clearance, described fuse is placed in fixing rubber bushing, suitable with fixing rubber bushing inwall, described fuse is fixed on inner tube the inside by fixing rubber bushing, described spring is turriform spring, the material of spring is 65Mn spring steel, described spring one end is connected with coil, the spring other end is connected with fuse bottom electrical.
By adopting technique scheme, the utility model makes fuse be fixed on inner tube the inside by fixing rubber bushing, make fuse and coil, spring stable connection reliable, simultaneously can multiple same outer diameter for subsequent use, the fixing rubber bushing of different inner diameters size, inner tube can be stablized different size fuse is installed, expand the voltage transformer scope of application, improve applicable performance, be convenient to install.
