Falling foreign matters and piercingIf 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,Dudelange800 dry type transformer quotation, which is not suitable for too large or too small.Dudelange, 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.How much is the power transformerAmadora,Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.Some are tied with plastic tape, and some immediately press the two edges together,DudelangeRequirements for oil immersed transformer room, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.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.

Common problems of tap changer of power transformerThe top and middle of the transformer oil tank, the flange plate, barrel skin and the middle of the waterproof sleeve at the upper end of the automobile oil tank. The internal iron core and winding clamp are hot due to partial magnetic leakage, resulting in insulation damage.On load commissioning:Installation requirements,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.The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, resulting in heat, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.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.

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?Application process,Noise pollution control and prevention measures of dry-type transformerTransformer manufacturers generally adopt IP protective casing, which can avoid the entry of solid dirt with a diameter of more than mm rats, snakes, cats, birds and other animals, resulting in vicious common faults such as short-circuit fault and power failure and provide a safe natural barrier for the energized part. If the transformer equipment must be outdoors, which can avoid being equally divided with the above IP protective effects However IP protective casing can be adopted, IP casing will reduce the refrigeration capacity of the transformer, so pay attention to the reduction of its operating volume.Before no-load impact closing, the pose period of overcurrent protection shall be set to zero, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.Dudelange, the transformer shall be placed for h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.
