Vertical external oil metal corrugate conservator for transformer is latest generation of the whole sealing type conservator by Shenyang Tiangong Power Technology Co., Ltd. (Shenyang Tiangong Power Equipment Co., Ltd.) , is the all-around products with the most ideal structure and the most excellent performance, has the characteristic of good sealing, long service life, maintenance free, convenient installation, is suitable for all kinds of the power equipments such as oil-immersed transformers, capacitors and reactors.
1. Installation and oil injection
①Release pressure: Open the breath vent, exhaust vent and oil injection vent, release the internal pressure of the conservator, and when opening the vent, it should be inhaled strongly.
②Installation: The conservator is installed in the position, connected with the transformer pipeline, and fix conservator. Connect the oil injection pipe and exhaust pipe to the lower part of the transformer and connect the valve with reliable seal. Connect the control circuit of oil level alarm device. After installation, prepare oil injection.
③Inject insulating oil: Open the valve of the breath vent and exhaust vent, and fill the conservator with oil from the transformer body or the oil injection vent;
④Exhaust: The oil level indicator is continuously raised after oil injection, and when the indicator is close to the value corresponding to the oil temperature (one calibration in advance), close the breath vent (with the plug). Continue to inject until the air in the conservator is discharged from the exhaust vent and the oil is stable outflow, then close the exhaust vent and stop the oil injection.
⑤Adjust the oil level: Open the breath vent to check whether the oil level is corresponding to the oil temperature curve. If the oil level is high, the oil should be properly discharged from the oil injection vent. If it is low, the oil can be replenished properly. The operation does not need to open the exhaust vent, but need to open the breath vent and keep opening.
※Note: The working state of the conservator is the breath vent is normally open, and the exhaust vent and oil injection vent are sealed reliably.
2. Vacuum oiling of conservator (the requirements should be mentioned when ordering)
If the conservator needs vacuum oiling together with transformer body, the exhaust vent must be connected to the vacuum system through "the transition jar", and the breath vent must keep opening when vacuuming, and meet the specification requirements of the pressure value (minimum 13 Pa). Open the oil valves, insulating oil under vacuum state will pass into the transformer tank and conservator. When insulating oil is discharged from exhaust vent into the transition jar, then quickly shut down and seal exhaust vent, and continue to inject oil through the oil injection vent to meet oil temperature corresponding to the oil level.
