LeightonDry type transformer procurementWhat checks should be done before use

If the volume of power transformer is too small the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.There are many connection groups of dry-type transformers, and the selected structures and connections are also different. Then, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.Leighton,First of all, although dry-type transformer has strong moisture resistance, it is generally open structure or very susceptible to moisture, especially the insulation level of dry-type transformer manufactured in China is low (lower flame retardant grade) Therefore, the dry-type transformer can obtain high stability only when the air humidity is below %. The dry-type transformer shall also be prevented from stopping operation for a long time to prevent serious damp. When the grounding resistance value is less than / V (operating voltage), it indicates that the transformer is seriously damp, and the trial operation shall be terminated.For the leakage that has already occurred,LeightonDry type transformer 1250kva, find the leakage point first, which can not be ignored. For the position with serious leakage shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage,LeightonDry type transformer Report, the goal of long-term treatment of leakage can be achieved.Victorias City the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation,When the full load test is carried out and everything is normal, the load can be connected.How much is the power transformerAfter 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.

The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.It should be said that after the development trend of these years, the overall level of China's transformer industry at this stage is basically international, and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?Potential development,The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?The conductor insulation of power transformer is the main part of internal insulation. Some conductors should pass through the middle of electromagnetic coil, or between electromagnetic coil, iron yoke clamp and automobile oil tank wall. Therefore, it is necessary to ensure that this kind of conductor has sufficient insulation compressive strength, i.e. insulation spacing.Noise solution of dry-type transformer

From the appearance, and only the shell can be seen for oil immersed transformer;Pursuit of excellence,(IV) the transformer on the column shall be stable and firm,LeightonInsulation grade of oil immersed transformer, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.Leighton, and some immediately press the two edges together, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.Oil leakage of cast iron partsThe iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core, which is stacked at the degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, which is resistant to corrosion and rust, and has sound insulation and noise reduction.
