S11-250KVAKW oil-immersed power box transformer User Notice:

1, unpacking inspection:

Whether the box is damaged during transportation; Whether the technical documents, certificates, warranty cards and accessories in the cabinet are complete; S11-250KVAKW oil-immersed power box transformer and other components are intact; Fasteners are loose and displaced, and terminals are in poor contact.

2. Instructions for positioning:

S11-250KVAKW oil-immersed power box transformer installation site must be dry and ventilated, no strong vibration, no ash sand rain leakage; Be careful to move in place, it is strictly prohibited to tilt too much, after the machine chassis force should be uniform, the box is placed smoothly; There should be enough space around the location to ensure ventilation and maintenance of the machine.

3, insulation requirements:

Short-connect the "input" and "output" terminals and lead out the test point, the test point to the ground (machine housing) with a 1000 megohm meter to test the insulation resistance, the value should be greater than 2 megohm.

4. Check the wiring:

The step work of the debugging personnel is also an important work is to carefully check the wiring, which is the key to ensure the reliable operation of the S11-250KVAKW oil-immersed power box transformer, and must be carefully done.
