Analysis of common faults of oil immersed transformer:
The project cost is different. Compared with the purchase price of capacity transformer，MedanpecModel of control transformer， the purchase price of dry-type transformer is much higher than that of oil immersed transformer.
MedanpecIn order to promote the use of energy-saving transformers the Ministry of finance， the Ministry of industry and information technology and the national development and Reform Commission jointly promulgated the detailed rules for the implementation of energy-saving distribution transformers of energy-saving products benefiting the people project as early as ， providing subsidies of - yuan / KVA for energy-saving transformers.
How to reduce the failure of dry-type transformer?
NasindiThe vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer， and the vibration reduction solution is made at the cable bridge.
For 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.
Power transformers are also used for testing， which are called test power transformers. They can be divided into inflatable， dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations， power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision， It is used to carry out insulation compressive strength test under required current for various electrical products， electrical components and insulating raw materials.
The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer， and the vibration reduction solution is made at the cable bridge.
The domestic transformer market is slow
Different diversion methods， dry-type transformers mostly use silica gel waterproof casing， while oil transformers mostly use porcelain waterproof casing;
Latest consultationThere are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let"s master and consult in detail with the small editor of the dry-type transformer manufacturer.
If the power transformer stops running for more than h (if the allowable time should be reduced when the ambient humidity is & amp; gt; %)， it should be insulated before putting into use， and accurately measured with a V grounding megger. The insulation resistance from the primary side to the secondary side and the ground should be ^ mfl， and the insulation resistance from the iron core to the ground should be & amp; gt; mfl (note that the grounding device piece should be removed).
What is the important role of power transformer
The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct， which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment， the output capacity can be increased by %.

The equipment can eliminate the shortcomings found in the patrol inspection， clean the porcelain waterproof casing casing，MedanpecScb10 dry type transformer，MedanpecDry type transformer design， 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.
Brief introduction of zero line of power transformer
MedanpecThe 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).
Causes of fire in power transformer
A 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.
