Baoding oil - immersed transformer USES full - oil seal type. The expansion of the corrugated oil tank shell is a permanently sealed oil tank. The oil-immersed transformer has been widely used in power distribution equipment.

Preparation for oil immersed transformer installation

1. Working hours :(according to the national standard) the comprehensive working day required for ontology installation is 21 working days. The work content includes: unpacking inspection, body position, body inspection, casing, oil pillow and radiator cleaning, oil column experiment, accessory installation, making and installation of cushion and wheel stopper, integral sealing test of supplementary column and after installation, grounding, painting, etc. Whether the transformer needs to be dried during the installation process, shall be determined after inspection and judgment, and shall be dried. The working day shall be 20 days after drying by iron loss drying method, and the working day for oil filtration shall be 3.38 working days/ton. The working day for debugging shall be calculated separately.

2. On-site arrangement of oil immersed transformer installation in baoding: overhaul and assembly of power transformer should be carried out in the maintenance room. If there is no maintenance room, it is necessary to choose the temporary installation place. It is better to place the transformer near the foundation platform of the transformer, so that the transformer is in place, or it can be installed on the foundation platform. There should be tent on the outdoor site. The temporary installation site must be easy to transport, the road is flat and wide enough, the ground should be solid, flat and dry, away from smoke Windows and water towers, and close to nearby buildings to meet fire safety requirements.

3. Designated safety measures: prevent the occurrence of accidents such as electric shock, falling and so on. Avoid insulation overheating. Protect against fire. Prevent STH from falling into the oil tank. Prevent attachment damage. Protect transformer from toppling.

4. Make technical measures: connecting to prevent transformer cores from getting damp. How to ensure that the connection parts are in good contact. Ensure all sections are well sealed and do not leak oil. How to ensure transformer insulation and oil insulation.

5, baoding oil-immersed transformer installation work of the basic procedures: (1) the preparation (tools, materials, equipment, drawings) (2) the inspection of the insulation and judgment (mainly coil and iron core) (3) the attachment check (should be complete, intact) (4) hanging core check (to prevent moisture absorption and tools, parts and other fell into the tank) (5) the attachment installation (appearance inspection, measuring and insulation tight line test) 6. 7) handover testing commissioning work at the end

6. Organization and division of staff: the installation chief and technical director shall be the safety officer and the oil filter team leader and the hoisting and transportation personnel and the test personnel shall be the installer.

7. Requirements for the transformer room: the faucet is fully ventilated with a safe distance of up to 100%; the base should be firm; the hoisting facilities should be in good condition.

8. Material preparation for oil immersed transformer installation in baoding:

First machine (such as vacuum pump, oil pump, oil tank, compressed air machine, oil filter, welding machine, line lamp transformer, valve, various spanner, etc.)

Test instruments (such as meter, dielectric loss Angle tester, booster transformer, voltage regulator, ammeter, voltmeter, power meter, thermometer, etc.)

Hoisting gear (such as crane, hanger, beam, hoist, wire rope, pulley, chain crane, etc.)

Insulation materials (such as insulating oil, cardboard, tape, electric wood insulation paint, etc.)

Sealable materials (such as right rubber gasket, asbestos rope, steel underlay, insect rubber paint, nylon rope, etc.)

Bonding materials (such as epoxy resin glue, glue, cement, sand paste, etc.)

Germ-free cleaning materials (e.g. white cloth, alcohol, gasoline, etc.)

Other materials (such as asbestos sheet, square wood, wire, steel pipe, oil filter paper, vaseline, enamel, etc.)

9. External inspection of baoding oil immersed transformer:

No mechanical damage

The bolts on the bellows cover are in good condition

The liner is well sealed

The casing surface is free of defects

No oil leakage and leakage phenomenon

D. stainless and complete paint

We have all accessories in good condition

The wheel distance of roller is consistent with the base track gauge.
