Installation, use, maintenance and storage of HVT60-220/220 35KV PT single-phase transformer
1. Pre installation inspection
The inspection items generally include: whether the product model and specifications are consistent with the purchase contract; 1.2 Whether the random files are complete;
Whether the appearance of the product is damaged during transportation; Electrical performance test
a. Measurement of inter group and ground insulation resistance; b. Short time power frequency withstand voltage test of winding;
c. Short time power frequency withstand voltage test of winding to ground; e. Discharge measurement; f. Error testing;
Installation and use: The installation base should be kept flat, and electrical spacing should be ensured between phases. The base should be fastened to the product installation base plate with fasteners and should not be loose; The wiring between the primary and secondary output terminals must be firm and reliable, and the secondary output terminal must not be short circuited and reliably grounded; To ensure reliable operation, the installation base plate must be reliably grounded; The product can be put into normal operation after being inspected, accepted and installed by the user, and meeting the conditions for power supply or distribution handover.
3. Maintenance: Due to the simple structure of the product, regular maintenance is required during use. Dust on the surface of the equipment should only be removed during regular maintenance; And conduct preventive trials; Such as insulation resistance measurement, partial discharge measurement, and error performance testing.
4. Storage: The storage conditions of the product should meet the requirements of Article 2.
Under the condition that the user complies with the storage, installation, and use rules, within 12 days from the date of installation and use, but only within 18 months from the date of shipment from the manufacturer, if the product is damaged or cannot function properly due to poor manufacturing quality, the manufacturer shall replace or repair the product or parts for the user free of charge.
