Device machine body structure.
Background technology
Society is higher and higher to power supply quality and reliability requirement, and power supply can be ensured by lifting the anti-short circuit capability of transformer
Safety and equipment safety.Amorphous alloy distribution transformer is due to structure, its winding is rectangle, amorphous core brittleness
With objective problem the makes amorphous alloy distribution transformer such as thickness is small always there is anti-short circuit capability it is insufficient the shortcomings that.
The key of lifting amorphous alloy distribution transformer anti-short circuit capability is to strengthen its own mechanical of rectangle high-low pressure winding
Intensity, and be reliably fixedly clamped to high-low pressure winding by folder, and amorphous core is from external force pressure.When transformer is prominent
Send out under short-circuit conditions, short-circuit electromotive force is pinned without excessive the destructive power of winding by folder that to be transmitted to iron core etc. other easily
Damage component and transformer is withstood the impact of sudden short circuit.
Current amorphous alloy distribution transformer is relatively low by the ratio that sudden short circuit is tested, and take mostly high-low pressure around
The mechanical strength of the mode lifter body of group dipping lacquer, considers that this method is all uneconomical from technological operation and environmental protection etc.
's.
Non-crystaline amorphous metal often only has 3 kinds with band, be respectively 142mm, 170mm, 213mm, capacity for 200KVA and its more than
Transformer nearly all using double-deck 8 groups of structure composition iron core, it is in prolate shape that winding is basic after being coiled into, to resistance to shorting extremely not
Profit, even if there is hard insulating cylinder to support inside low pressure winding, in the case of sudden short circuit hard insulating cylinder also can because be subjected to impact and
Middle part weak spot damage.And the outer core of A phases and C phases can be because of change of rising outside the high-voltage winding of A phases and C phases in the case of unprotect
Shape and damage.
