After no-load test run is normal for h， it can be transferred to on-load operation， and the load shall be gradually increased from %， 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， while the working voltage， current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer， and can be solved until power failure.
It will also produce many faults， effectively deal with various faults of oil immersed transformer， make full use of the performance indicators and advantages of oil immersed transformer，CuritibaRecovery price of dry-type transformer， and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault，CuritibaPrice of 125kva dry type transformer， and short-circuit fault is more general.
Caused by sand holes and cracks. For crack leakage， drilling stop hole is a good way to remove in-situ stress and prevent widening.

Precautions for trial operation of power transformer manufacturers
After 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， the human resources traction belt shall be used as a guide.
knowledgeWith 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， but also the winding and other structures of the oil immersed transformer can be effectively arranged and distributed in a certain scope which greatly facilitates the design scheme of the oil immersed transformer and ensures the stability of operation.
Dry type transformer manufacturer
Difference between dry-type transformer and oil immersed transformer:
For 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，CuritibaPower system transformer， 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， office and other electrical equipment.
Respect for customersWhen the power transformer operates at full load， it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large， it will not only increase the initial project investment， but also make the transformer operate at full load or load for a long time， reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.
The equipment can eliminate the shortcomings found in the patrol inspection clean the porcelain waterproof casing casing， remove and replace the cracked or brittle leather pad， check and tighten the node， replenish the oil with less oil， check and replace the silica gel of the breathing mask， etc.
The oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.
CuritibaA zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable， the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let"s introduce it to us.
Causes of fire in power transformer
In the case of dry-type transformer operation， there is more noise， and some even cause noise， which seriously endangers everyone"s no problem rest time and work. At this time， the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer"s network editor to simply understand it.
