Description
Technical field
The utility model relates to a kind of voltage transformer, is specifically related to a kind of voltage transformer with fuse.
Background technology
At present, voltage transformer is the device utilizing electromagnetic induction principle to change voltage value, and a kind of special transformer being defined structure and type of service, is widely used in the transmission of electricity such as power plant, electric substation and electric power system specifically; The quality of its service behaviour and reliability directly affect the fail safe of whole power supply grid, are related to industrial every field.Fuse is the simplest protective device, is used for protecting electric equipment from overload and the infringement of short circuit current.And the voltage transformer of existing band fuse exist unstable properties, security performance low, defect is easily installed not.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides that a kind of structure is simple, safe and reliable, the voltage transformer of the band fuse of installing convenient, stable performance.
For achieving the above object, the utility model adopts a kind of voltage transformer of fuse, comprise epoxy resin poured body, iron core, be wrapped in the secondary coil on iron core, secondary coil goes between, be sleeved on the primary winding on secondary coil, primary winding goes between, secondary wiring terminals, the exit of described secondary coil lead-in wire is provided with Metal Contact sheet, fuse is provided with between described Metal Contact sheet and secondary wiring terminals, described fuse comprises fusible core and places cavity, place cavity with fusible core to be threaded and the lid being arranged on epoxy resin poured body outside, be arranged on the fusible core in fusible core placement cavity and spring, one end of described spring is arranged on the upper surface of fusible core, this spring other end is conflicted on the inwall of lid.
The beneficial effects of the utility model are: be provided with fuse between the exit that this voltage transformer goes between at secondary coil and secondary wiring terminals, when voltage transformer runs into overvoltage, when overcurrent or internal fault, fuse fuses automatically, instrument transformer and extraneous circuit are isolated, protection instrument transformer is not burnt, and the fusible core of this fuse is arranged in fusible core placement cavity, and be provided with spring between fusible core and lid, thus ensure that fusible core and Metal Contact sheet, the connection of secondary wiring terminals is compacter, and fuse is provided with the lid be exposed at outside epoxy resin poured body, thus be convenient to the installation of fusible core, after fusible core damages or fuses, also the replacing of fusible core is convenient to.
Accompanying drawing explanation
Fig. 1 is that the utility model implements main TV structure schematic diagram.
Fig. 2 is that the utility model implements left TV structure schematic diagram.
Embodiment
As Fig. 1, shown in 2, the utility model embodiment is a kind of voltage transformer of fuse, comprise epoxy resin poured body 10, iron core, be wrapped in the secondary coil 11 on iron core, secondary coil lead-in wire 111, be sleeved on the primary winding 12 of on secondary coil 11, primary winding goes between, secondary wiring terminals 13, the exit of described secondary coil lead-in wire 111 is provided with Metal Contact sheet 112, fuse 20 is provided with between described Metal Contact sheet 112 and secondary wiring terminals 13, described fuse 20 comprises fusible core and places cavity 21, place cavity 21 with fusible core to be threaded and the lid 22 being arranged on epoxy resin poured body 10 outside, be arranged on the fusible core 23 in fusible core placement cavity 21 and spring 24, one end of described spring 24 is arranged on the upper surface of fusible core 23, this spring 24 other end is conflicted on the inwall of lid 22.Fuse is provided with between the exit that this voltage transformer goes between at secondary coil and secondary wiring terminals, when voltage transformer runs into overvoltage, when overcurrent or internal fault, fuse fuses automatically, instrument transformer and extraneous circuit are isolated, protection instrument transformer is not burnt, and the fusible core of this fuse is arranged in fusible core placement cavity, and be provided with spring between fusible core and lid, thus ensure that fusible core and Metal Contact sheet, the connection of secondary wiring terminals is compacter, and fuse is provided with the lid be exposed at outside epoxy resin poured body, thus be convenient to the installation of fusible core, after fusible core damages or fuses, also the replacing of fusible core is convenient to.
