10.2 Baada ya bidhaa kuondoka kwenye kiwanda, nafasi za bomba za upande wa shinikizo la juu huunganishwa kulingana na nafasi ya thamani iliyokadiriwa. Marekebisho ya voltage inahitajika wakati wa operesheni. Kwa mujibu wa voltage ya bomba iliyoonyeshwa kwenye nameplate ya bidhaa, awamu tatu zinarekebishwa wakati huo huo kwenye uunganisho wa bomba unaofanana (wakati hakuna msisimko na udhibiti wa voltage), na ugavi wa umeme wa transformer hukatwa.

10.3 The transformer adopts the BWDK series thermostat, and the temperature measuring element is embedded in the upper end of the low-voltage coil, which can automatically detect and display the respective working temperatures of the three-phase coils. When the coil temperature reaches the set temperature, the thermometer can automatically start the fan, stop the fan, alarm, trip, and the set temperature can be adjusted by the user.

 

11. Matengenezo

Baada ya kibadilishaji cha aina kavu kwa muda mrefu, nguvu inapaswa kukatwa na ukaguzi na matengenezo muhimu yafuatayo yanapaswa kufanywa.

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 Baada ya ukaguzi na matengenezo kukamilika, kabla ya transfoma kuanza kufanya kazi tena, inapaswa kuangaliwa kwa uangalifu ikiwa kuna chuma chochote cha kigeni cha chuma au kisicho na metali kimeshuka, kilichoachwa kwenye msingi wa coil na chuma na kwenye sehemu za kuhami joto.

 

12. Mambo ya usalama
