summary
S11-M-302500/20-10 fully sealed oil immersed transformer is suitable for power systems with AC 50Hz, rated working voltage of 10KV, 20KV and below. It is used as a distribution transformer for enterprises such as petroleum, metallurgy, chemical, textile, light industry, and places with high dust content.
structure characteristics
Iron core
The iron core is made of high permeability grain oriented cold rolled silicon steel sheets. The iron core is a core type iron core, with a fully inclined seam stacked iron core. The iron core column has a multi-stage stepped circular cross-section, and the iron core and iron core have equal cross-sections.
winding
The winding adopts a tile oil channel, without painting process, and is bound with tightening tape; The windings are all concentric coils, and the high-voltage winding has taps corresponding to the tapping voltage requirements, which are led to the tapping switch. The switch is installed on the box cover and can achieve voltage transfer of 10kV and 20KV after cutting off the power supply, as well as changing the tapping voltage.
Safety protection device
30-2000kVA transformers are equipped with pressure relief valves gas relays with alarm and trip terminals can be installed according to user requirements:
Oil temperature measurement device
Transformers are equipped with tube holders for glass thermometers, which are located at the top of the oil tank and extend 120 ± 10mm into the oil; 1000-2000KVA transformers are equipped with outdoor signal thermometers;
Transformer oil tank
The transformer oil tank is composed of corrugated walls, and the surface is sprayed with dust and the paint film is firm. The corrugated heat sink not only has cooling function, but also has "breathing" function. The elasticity of the corrugated heat sink can compensate for the changes in transformer oil volume caused by temperature rise and fall. Therefore, the fully sealed transformer does not have an oil storage tank, which reduces the overall height of the transformer;
The transformer is packaged using a vacuum oil injection process, which completely removes moisture from the transformer and prevents the transformer oil from coming into contact with air. Effectively preventing the invasion of oxygen and moisture into transformers, which may lead to a decrease in transformer insulation performance and aging of transformer oil, therefore conducting oil sample tests irregularly;
