When the screw of the through core extruder holding the iron core of the transformer is loose, there are screw cap parts left on the iron core, or small metal materials fall into the transformer, the transformer will send out & ldquo; Ding Ding Dang & rdquo; Or & ldquo; Call & hellip; Call & hellip& rdquo; Blowing sound and its & ldquo; Squeak, squeak & rdquo; It's like a magnet sucking a small washer while the working voltage, current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer and can be solved until power failure.Noise solution of dry-type transformerZabrzeh,Hand touch method for transformer inspectionDry type transformer factoryOlsk,The voltage regulating tap changer is not in place or poorThere are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let's master and consult in detail with the small editor of the dry-type transformer manufacturer.In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.

From the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.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, which is conducive to adjusting the data and has a unique and neat style.Respect for customersDifference between dry-type transformer and oil immersed transformer:The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness, resistance to short-circuit faults, common faults and impact. The work is diligent.After hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.

The no-load impulse closing working voltage shall not exceed % of the working voltage marked on the gear of the transformer, the closing frequency shall be times, and the time interval of each closing shall not be less than min.market price,ZabrzehParameters of oil immersed power transformer, a static electrical equipment, is used to change the AC current (current) of a certain standard value into another or several types of working voltage (current) with the same frequency and different standard values. According to the supervision sampling inspection data of the third quarter of last year released by AQSIQ, among the kinds of dry-type transformer commodities manufactured by manufacturers in provinces and municipal districts across the country, kinds of commodities were found to be inconsistent with the provisions of relevant specifications, with a compliance rate of %& ldquo; This result mostly shows the quality level of China's dry-type transformer industry at the present stage.If you want to check the activated carbon fiber for the hanging cover, first take out the low-voltage waterproof sleeve and the on load transformer power switch, then lower the bell cover anchor bolt of the large cover, slowly hang the galvanized steel wire rope with sufficient lifting net weight on the commonly used earrings, and count the spacing and specifications for easy reinstallation. At the same time, the cable wind shall be added on all sides to ensure that the core international body will not be damaged during the whole lifting process. After lifting for mm, stop the lifting, stabilize the bell cover, and check the bearing capacity of the lifting core,ZabrzehParameters of scb11 dry type transformer, center of gravity and Jack. After everything is normal, lift it again until the bell cover exceeds the relative height of the body, and rotate the crane to place the bell cover on the clean skid.Zabrzeh,Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area,ZabrzehComputer temperature controller for dry-type transformer, but also reduce the voltage to each application voltage, so as to meet the needs of power consumption. In short, voltage transformation and blood pressure reduction must be carried out by the transformer.The method and whole process of taking oil sample of power transformer are as follows:The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.
