Product Description

HONLE SZ 11-M Series 400kVA Three Phase Oil Immersed Distribution Transformer


Overview
Iron core:
The iron core is made of high-permeability grain-oriented cold-rolled silicon steel sheet. Fully oblique seam stacked iron core, the iron core column has a multi-step circular cross section, and the iron yoke and the iron core have the same cross section.

Coil:
The firing group adopts corrugated oil passage, non-immersed paint process, and tightening banding; the firing group is all concentric coils; the high-voltage firing group has taps corresponding to the requirements of the tap voltage, which is led to the decomposition switch, and the switch is installed on the cover It is necessary to cut off the power before changing the tap voltage.

Oil tank:
The transformer oil tank is composed of corrugated walls, the surface is sprayed with dust, and the paint film is firm.
The corrugated fins not only have the cooling function, but also have the breathing function. The elasticity of the corrugated fins can compensate for the change in transformer oil volume caused by the temperature rise and fall. Therefore, the fully sealed transformer has no oil storage cabinet, which reduces the overall temperature of the transformer.

Transformer adopts vacuum oil injection process during packaging, which completely removes the moisture in the transformer, and the transformer oil is not in contact with air. Effectively prevent oxygen and moisture from intruding into the transformer, resulting in degradation of transformer insulation performance and aging of transformer oil, which improves the feasibility of transformer operation.

Insulation structure:
Oil-immersed distribution transformer adopts -level insulation structure; high voltage coil and low voltage coil are concentric; the space between coils is cardboard sleeve small oil clearance oil partition structure.
