6.1   The products are divided into two types: open type (without protective cover) and protective type (with protective cover), which are usually transported by railway, waterway and highway. Switches, thermostats, air- cooling devices, external protective devices, etc. need to be packaged separately) or packaged as a whole for transportation. Cranes, winches or other corresponding transportation machinery can be used to lift and unload the products.

6.2   During the transportation of the product, there must be rainproof measures to prevent rainwater from drenching.

6.4   During transportation, there should be no up and down slopes greater than 15° on the transportation line. In order to ensure that the vehicle can bear the load evenly, the center of gravity of the product should be located on the vertical centerline of the vehicle during loading. In order to prevent

displacement and overturning of the product during transportation, the direction of the long axis of the product should be consistent with the transportation direction, and the product should be firmly bound on the transport vehicle.

6.5   When loading and unloading without a crane, the safety technical requirements should be met, and the lifting capacity should be checked to see if it matches the transport weight of the product.

7. Inspection and acceptance

7.1   After receiving the product, the user should open the box for inspection and acceptance in time, check whether the items listed in the packing list are complete, check whether the transformer is damaged during transportation, whether the product parts are damaged and displaced, and whether the fasteners are loose, whether the insulation is damaged and whether there are traces of contamination, etc.

7.2   Check whether the data on the product nameplate is consistent with the product specification, capacity, voltage level, connection group label, short- circuit impedance, etc. specified by the user.

7.3   After the product is unpacked and checked, if it is not put into operation immediately, it should be repackaged and placed in a safe indoor place (anti- theft, moisture-proof, dust-proof, anti-fouling, anti-collision) to warn the storage of the product.

8. Visual inspection before installation

8.1   After opening the box, remove the guards (if any) to check the external condition, paying particular attention to the mechanical integrity of the coil and the core, the degree of compression of the wire circle and the core, and the tightening of the bolts outside the connection.

 

 

 

 

 

8.2 Bayan dubawa, duk fasteners da ɓangarorin matsawa na coils da baƙin ƙarfe dole ne a sake ƙarfafa su a jere, kuma ba a yarda da sassautawa ba.

8.3   Reset the dismantled parts in accordance with the provisions of the factory technical conditions and the relevant instructions of the complete set of componentsInstalled on the transformer body.

8.4   For dust and dirt on the product, try to use dry compressed air. In special cases, such as cleaning with a rag, the cloth must be dry, clean and lint-free.

8.5   When the storage time is long, there are water droplets or serious condensation on the surface of the transformer, you should take dry treatment, and the coil can be used after the insulation performance of the coil is qualified.

 

9. Gwajin dubawa kafin a fara aiki

9.1   Measure the DC resistance of the high and low voltage windings (whether the data is consistent with the data given in the factory test certificate).

9.2   Check the grounding of the iron core (the grounding piece is generally located at the end of the lower iron yoke or the upper iron yoke), check whether the grounding is reliable, whether there is foreign matter overlap, and whether there is a multi-point grounding phenomenon.

9.3 Auna juriya na Insulation

Low voltage coil (0.4V) to ground	50MΩ	50MΩ	50MΩ
Core to ground	5MΩ	5MΩ	5MΩ

 

9.4   When doing the power frequency withstand voltage test, the temperature control probe wire should be taken out from the wire enclosure to prevent the breakdown of the internal components of the thermostat, and even the breakdown of the transformer coil.

9.5 Bincika ko tsarin kariya yana cikin yanayi mai kyau.

9.6   The installation position of the transformer should be at least 800mm away from the wall and other objects that affect the heat dissipation conditions. After the transformer is in place, the grounding bolts should be connected to the general grounding circuit for reliable grounding.

10.2 After the product leaves the factory, the tap positions of the high pressure side are connected according to the rated value position. Voltage adjustment is required during operation. According to the tap voltage indicated on the product nameplate, three phases are simultaneously adjusted on the corresponding tap connection (when there is no excitation and voltage regulation), and the power supply of the transformer is cut off.

11. Kulawa

After the dry-type transformer has been running for a period of time, the power should be cut off and the following necessary inspections and maintenance should be carried out.

11.1 Check coils, sealing wires, tap terminals and fasteners in various parts for damage, deformation, loosening, discoloration, discharge traces and corrosion. measure.

11.2 Remove dust from the transformer. All parts that can be touched by hands should be wiped with a clean, lint-free dry cloth, etc., but no volatile cleaners should be used. For the hard-to-wipe parts inside the iron core coil, dry compressed air should be used to blow off the dust.

11.3 The transformer equipped with the fan should also remove the dust and soil in the fan (be careful not to deform the blades of the fan due to damage) and check the grease of the fan bearing, and supplement or replace it if necessary.

11.4 After the inspection and maintenance are completed, before the transformer is put into operation again, it should be carefully checked whether there is any metal or non-metallic foreign matter dropped, left in the coil and iron core and on the insulating parts.
