KonalfDry type transformer sampleInspection and replacement operation

What is the wiring mode of dry-type transformer?After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.Konalf,The insulation of the through core anchor bolt clamping the iron core is damaged, resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;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.Ouazzane,If the oil immersed transformer is burned by the cover of the transformer, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.With the rapid development of society and the continuous development trend of computers, the calculation of data in the whole process of oil immersed transformer wave has long had results. Only effective selection of calculation entity models and methods is needed, the accuracy of calculation conclusions can meet the needs of architectural design, and scientific and reasonable data method is selected, Not only can the current distribution of the oil immersed transformer be clearly defined in the development stage, which greatly facilitates the design scheme of the oil immersed transformer and ensures the stability of operation.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.

The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.If the input of dry-type transformer is an alternating switching power supply, its output voltage is directly proportional to the coil turn ratio of the output input solenoid coil. If a rechargeable battery is used, because it is DC, add a circuit in the input power supply circuit to change it into a continuously changing voltage. In that way, the alternating DC current can be obtained at the output end.Operation of oil immersed transformerQuality management,In specific daily life,KonalfRecycling power transformer, oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact, the wave height of oil immersed transformer also shows the size of kinetic energy. Generally, computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is, the greater the output power is. On the contrary, it is very small.When the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.

Oil leakage of bolt or pipe external threadWelcome calls ,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,KonalfSelection of dry type transformer, while the working voltage,Konalf4000 dry type transformer size, current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer, to occupy the main global technical position, commodity volume and voltage level. As early as & ldquo; Eleventh Five Year Plan; In the early stage, China has been a powerful country in the production, manufacturing and application of dry-type transformers all over the world, but it is not a big country.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.Konalf,The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of -A / Min.How much is the power transformerFor kVA power engineering transformer plastic parts are selected in the middle of iron core, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.
