IcelandAutomatic power transmission of transformerWhat is the common delivery status

Power transformers are used in all walks of lifeThe zero line is mainly used in the working circuit. The voltage caused by the zero line is equivalent to the line resistance multiplied by the current of the working circuit. Because of the distance, the voltage caused by the zero line can not be ignored. As a countermeasure to maintain life safety, it is more and more unreliable. Ground wire (PE): it is not used as a working circuit, but only as a maintenance line. Use the affirmation of the earth & ldquo; ” Voltage. When the machine and equipment casing is electrified the current will be quickly grounded. Even if there is a lead for the PE line, it will be grounded from the surrounding grounding body.Iceland,The 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.The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.General,Iceland500 KVA dry type transformer,Careless maintenance and insulation damageThe main reason is that the welding quality of electric welding is poor, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.Power transformers are used in all walks of life

In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, 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.Dry type transformer companyClick to view,Before application, the sampling container shall be cleaned with vehicle gasoline, soapy water or other organic solvents (such as trisodium phosphate) except oil stains,IcelandPower electronic control, and then washed with tap water until it is not alkaline, and the water can be evenly distributed from the bottle, and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a ℃ drying oven. After refrigeration, the bottle cap shall be tightly closed and cannot be opened before application.When using the oil sample of the power transformer in operation, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about kg of waste liquid stored at the bottom to clean the oil inlet, and then take the oil sample.Dry type transformer manufacturer

The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?Good quality,For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, it is very easy to cause fire accidents, power failure, damage to machinery and equipment, etc.Oil sample inspection & mdash; & mdash; the performance parameters such as compression resistance and residue shall be carried out every three years. The long-term overload or overload of the transformer can reduce the cycle time.Wiring mode of dry-type transformer:Iceland,IcelandDry type transformer 2500kVA,For no-load impulse closing of transformer pay attention to the following matters:Loose core screwThe long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils, two-color short circuit or short circuit on the ground, the insulation compressive strength of power transformer shall be tested before installation and operation, and overload is not allowed in the whole process of operation.
