How much is the power transformerIt is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.Badwaslau,Many people probably don't know much about the power distribution transformer manufacturers. In fact, the transformer can be plugged in for trial operation after careful inspection before capital investment. During the trial operation period, you must pay attention to the following points. Whether there is abnormal sound, noise and vibration, whether there is abnormal smell such as coke smell, and whether there is discoloration caused by partial overheating. Ventilation is good. In addition, the resistance value exceeds m ohm bus.Santa-Clara,When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,The main reason is that the welding quality of electric welding is poor there are empty welding, 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,BadwaslauWhat qualifications are required to install power transformers, 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 fact, ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them, safety factor grounding device can be divided into grounding protection, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?Quality management,How to reduce the failure of dry-type transformer?The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.What is the wavelength of oil immersed transformer?
After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak,How much is the power transformerUnder normal conditions, different oil-based oils cannot be mixed. Under special circumstances if it is necessary to use new oil of different grades, and then the oil mixing test should be carried out.& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by V megger it should be determined whether the mixed oil with ice degree can be used according to the requirements of the region, the resistance value exceeds m ohm bus.Badwaslau,BadwaslauWhat is the price of 1600KVA transformer,Protective measures for damping of dry-type transformerAccording to the condition of cracks,BadwaslauDry type transformer 125kva, 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.The time difference between different steps of three-phase power switch of switching power supply shall be less than ms, the closing shall be maintained by high-voltage arrester, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).
