Himoinsa has developed two transformer substations, the HRS 6300 D5/6 and HRS 3150 D5/6 in 20ft and 10ft container versions, respectively, by using four generator sets connected in parallel to the same station. These substations make it possible to transform 6.3 MVA and 3.15 MVA depending on whether a 20 or a 10ft container is used. The transformer substations make it possible to increase the voltage from low to medium, or vice versa, depending on project requirements.Â
The HRS 6300 D5/6 model has each 20ft container fitted with two 3,150 kVA transformers for adjusting the necessary voltage in reduced spaces and avoiding the need to connect each generator set to individual electricity transformers. The 10ft container provides the same transformation and manageability functionalitiesas its 20ft counterpart, but it is able to connect two generator sets working in parallel with a maximum power of 3,150 kVA. It features a single transformer, one medium voltage and another low voltage cell, an auxiliary control panel and a quick-connection set for medium voltage.
The HRS 6300 D5/6 and the HRS 3150 D5/6 models incorporate a digitally-controlled transformer protection relay with measurements that is able to detect the oil pressure to guarantee the safety of the transformer and any equipment that is attached to it. The design of both substations allows medium/low voltage connections to be made with the help of a built-in connector set.
