Mining Oil-immersed Transformer Feature

-HENGFENGYOU KS series mining transformers are made of silicon steel sheets with high oriented magnetic conductivity. The iron core is a core type iron core and a fully inclined seam stacked iron core. The iron core column is a multi-level circular section to ensure low noise and low loss, and the oil tank structure is firm.

-The two sides of the box wall are welded with high and low voltage cable junction boxes, which are used as cable connection. The high voltage coil must have a rated voltage of 5%. The switching power supply must be cut off when the tap changer is used to convert the voltage to the voltage, and then the tap changer is adjusted to carry out the transformation voltage.

-The low-voltage side of the transformer allows "Y" type to be connected into 693v or "d" type to be connected into 400V power supply. The secondary end is directly installed in the cable junction box, and six porcelain sleeves are led out for the user to connect the transformer. The lifting lug welded on the box wall is used for the lifting of the transformer. The bottom of the transformer box is equipped with a drag sled. The drag sled is equipped with installation holes to supply ore and add ore car rollers when necessary.

Mining Oil-immersed Transformer FAQ

What is a mining oil-immersed transformer?
It is a type of transformer designed for mining operations, using oil as a cooling and insulating medium to withstand harsh environments.
What are the key features of mining oil-immersed transformers?
They are built with robust materials, high-temperature resistance, and enhanced safety features to operate in dusty, humid, and high-load mining conditions.
How does the oil in the transformer function?
The oil acts as both a coolant to dissipate heat and an insulator to prevent electrical discharges within the transformer.
What safety measures are in place for oil-immersed transformers in mines?
They include pressure relief devices, temperature monitoring, and flame-retardant materials to prevent fires and explosions.
How often should the oil be tested and replaced?
Regular oil testing should be done every 6-12 months, with replacement based on degradation levels and operational conditions.
Can mining oil-immersed transformers handle voltage fluctuations?
Yes, they are designed to manage varying load demands and voltage fluctuations common in mining operations.
What maintenance is required for these transformers?
Routine checks include oil level inspection, cleaning bushings, tightening connections, and monitoring cooling systems.
Are these transformers suitable for underground mining?
Yes, but they must meet additional safety standards for ventilation and fire resistance due to confined spaces.
What are the common causes of failure in mining oil-immersed transformers?
Overloading, oil contamination, insulation breakdown, and poor maintenance are typical causes of failure.
How do I choose the right oil-immersed transformer for a mining application?
Consider factors like load capacity, voltage requirements, environmental conditions, and compliance with mining safety regulations.
