which also ensures the rated voltage of kV; Oil immersed transformers are generally suitable for distribution equipment.The tap changer of power transformer shall also have strong insulation. kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.Valkyakowski

The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below kVA and the working voltage is below KV,During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.Loose core screwKelebang Besar,& ldquo; YN, D & rdquo;, in which indicates that when the working voltage phasor of the primary side line, as the minute hand, refers to the position at o'clock, the phase voltage phasor of the secondary side is at o'clock. That is, the phase voltage UAB of the secondary side lags degrees behind the working voltage uab of the primary side line (or degrees ahead).Operation and maintenance management of oil immersed transformerOil leakage of porcelain pot and laminated glass oil level gauge

Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.The equipment can eliminate the shortcomings found in the patrol inspection, clean the porcelain waterproof casing casing, remove and replace the cracked or brittle leather pad, check and tighten the node, replenish the oil with less oil, check and replace the silica gel of the breathing mask, etc.& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by V megger, the resistance value exceeds m ohm bus.Analysis project,Dry type transformer manufacturerAvoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of .kg or kg. - bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name,ValkyakowskiDifference between box transformer and transformer, source, sampling date, sampling person,Valkyakowski1000 dry type transformer size, weather conditions and other materials of the oil sample.

In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, it will affect the whole power circuitMarketing Department,The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness,ValkyakowskiCapacity specification of 10kV power transformer, which is conducive to adjusting the data and has a unique and neat style.Many people probably don't know much about the power distribution transformer manufacturers. In fact, the transformer can be plugged in for trial operation after careful inspection before capital investment. During the trial operation period, you must pay attention to the following points. Whether there is abnormal sound, noise and vibration whether there is abnormal smell such as coke smell, we should also pay attention to the following aspects.Note: in the whole process of safety patrol inspection and whether there is discoloration caused by partial overheating. Ventilation is good. In addition, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded, the cause shall be found immediately and certain effective measures shall be taken. If necessary,The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of -A / Min.The key reason for oil leakage is that there are defects in cast iron parts
