With device and method.
Background technique
Amorphous alloy transformer is the power transformer of a kind of low-loss, high energy efficiency, using iron based amorphous metal as iron
The heart, since the material does not have long range ordered structure, magnetization and the more general magnetic material of degaussing ability are strong.Therefore, amorphous closes
The iron loss (i.e. no-load loss) of golden transformer uses silicon steel 70-80% low as the traditional transformer of iron core than generally.Due to damage
Consumption reduces, and power generation needs also decline therewith, and the discharge of carbon dioxide isothermal chamber gas is also corresponding to be reduced.Based on energy supply and environmental protection
Factor, amorphous alloy transformer is used widely.
Amorphous alloy transformer generally installs iron core using vertical installation method: iron core opens iron core under plumbness
Upper yoke, respectively penetrates the high-voltage coil and low-voltage coil of three-phase, then shuts the upper yoke of iron core.
But when opening and closing iron core, due to the inherent characteristic of amorphous alloy core, amorphous alloy
The heart easily fragmentation.Furthermore during implementation iron core vertical total coating process, operator is more, general assembly inefficiency.
Summary of the invention
The first purpose of the invention is to provide a kind of assembly devices of amorphous alloy transformer iron core, can effectively keep away
Exempt from amorphous alloy core and occurs the case where because of external force fragmentation when opening and closing, meanwhile, operator in assembling process
It reduces, general assembly efficiency improves.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of amorphous alloy transformer iron
The assembly device of the heart, including core-lamination stack supporting plate, the core-lamination stack supporting plate in trough type and its notch upward, the iron core is folded
