Note: in the whole process of safety patrol inspection, 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, or there is local sound, the cause shall be found immediately and certain effective measures shall be taken. If necessary, the load can be reduced or the operation of the transformer can be stopped.For no-load impulse closing of transformer, pay attention to the following matters:Asenuogler,The rate of transformer is: n = P / pxo% that is, when the copper loss of transformer is equivalent to iron loss, the rate is very large. Therefore, the load of transformer is: = P / PK. Fully consider the active power loss caused by reactive power in the system software during transformer operation. The load adjustment is: it can be seen from the calculation of load formula that the large rate of transformer does not occur when the load is full Generally, it is about %, but when selecting the transformer capacity, we should select effective transformers according to the load condition and load, so as to make the transformer in the situation of economic development and achieve the goal of power saving.Protective measures for damping of dry-type transformerAlto Barinas,Avoid the load operation of power transformer: if the load operation is long-term, it will lead to the scalding of solenoid coil, slow aging of insulation, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.Brief introduction of zero line of power transformerFor example, in the s, the radio programs applied by every family in the countryside had a ground wire, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, and then lead a point of it out of the road with transmission line, which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances, the fixed finger is at o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.Transformer manufacturers generally adopt IP protective casing, which can avoid the entry of solid dirt with a diameter of more than mm, rats, snakes, cats, 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, IP protective casing can be adopted, which can avoid being equally divided with the above IP protective effects However, IP casing will reduce the refrigeration capacity of the transformer, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, commerce, airports, tunnel construction, chemical enterprises and factories.Quality recommendation, most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building, and then causes gas vibration noise, the dispersion spacing and adverse effects are very large.Dry type transformer manufacturerThe technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ Ω The resistor is generally more than & omega;, when the insulating layer is damaged According to Ohm's law, the current is only / of the total current flow, so as to play a guarantee effect. The higher the voltage, the smaller the resistance,AsenuoglerOil immersed transformer gear, in other words, in the case of high voltage. We can care about the power transformer plant and master a lot of professional knowledge.

In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?Market trend,High voltage fuse of transformer breaks one phase;The appropriate power saving calculation formula should be derived from the following process: active power loss of large capacity transformer: load of large capacity transformer; PDK - short-circuit fault loss of large capacity transformer, kW. Active power loss of small capacity transformer: when a pump room is in normal operation, two pumps are started separately, and each pump is driven by kW motor, so the usual load is KW, CST = . One kva transformer was originally configured, and the capacity utilization rate introduced by the transformer manufacturer is only %According to the condition of cracks, galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.Asenuogler,Therefore,AsenuoglerImpulse test of dry-type transformer, in the operation prevention and regulation of relay protection dry-type transformer, it is necessary to find the short-circuit fault point according to the fault situation, lock the fault point, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear, disconnect the switching power supply at the fault point,AsenuoglerLarge oil immersed transformer, the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.Brief introduction of zero line of power transformerAfter the oil is drained, all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack, and the lifting point shall be on the common earrings or bolts. If necessary, the human resources traction belt shall be used as a guide.
