On load commissioning:During no-load test run the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.Saint Kitts and Nevis,Transformer inspection earPlug in the power with full load first, ignition check whether the equipment has abnormal sound, odor and other abnormal conditions. If there is any abnormality,Saint Kitts and NevisPrimary energy efficiency model of dry-type transformer, please cut off the input switching power supply.Cabral,After the test, connect the data signal contact of the automobile relay with the alarm circuit, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core, and long-term scalding of iron core will lead to insulation aging.The noise of dry-type transformer belongs to low-frequency noise. In a small area, most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building, and then causes gas vibration noise, which is then scattered to the ears of consumers. Although the amount of noise is not very large, the dispersion spacing and adverse effects are very large.

(IV) the transformer on the column shall be stable and firm, and the waist rail shall be & phi; mm galvanized wire shall be wound over turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than .m.Transformer inspection nose sniffing methodMethod and process of taking oil sample of power transformerWorkshop cost,When sampling in bulk gasoline barrels, samples shall be selected according to % of the number of gasoline barrels, but not less than barrels. When sampling in batches of small and medium-sized pails or bottles, samples shall be taken according to % of the total number of barrels (bottles).(III) dry type transformers of KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than m; The distance between the electrified part and the road surface shall not be less than m.Manufacturing process and steps of dry-type transformer

(I) the distance between the external contour of kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than m; At the angle with actual operation, a spacing of more than m shall be reserved; If metal fence is selected,Saint Kitts and NevisPrice of 3150kva transformer, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.Quality management,The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?Transformer inspection earTherefore,Saint Kitts and NevisAmorphous alloy distribution transformer, in the installation process of substation equipment, the lightning rod should be set according to the specific situation to prevent damage to the relay protection dry-type transformer caused by lightning. In addition, in the installation and use process of lightning rod, select reasonable types of lightning rod according to the operation situation to determine that they are in the same situation. In addition, during the installation of lightning rod please connect all routes as far as possible to prevent other faults.Saint Kitts and Nevis,The flange surface is uneven, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.The key reason for oil leakage is that there are defects in cast iron partsWhen the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large, but also make the transformer operate at full load or load for a long time, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.
