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， 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， and short-circuit fault is more general.
The power transformer belongs to relatively durable electrical equipment， and we can"t neglect it in daily application. The common problems of power transformer conductor， power transformer winding and power transformer tapping power switch are analyzed below:
TaguergonIn order to better avoid overvoltage damage， a group of overvoltage maintenance high-voltage Arresters (such as ycs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.
It includes the performance and main uses of insulating layer materials， various insulating layer parts， component manufacturing processes and quality standards; Performance and main uses of various wires， coil inductance process of various ways of electromagnetic coil， solution process and quality standard， overall suit process and quality standard of electromagnetic coil; Main performance parameters of ferrite core，TaguergonHow much is a 50 KVA box transformer，TaguergonDry type transformer unit， cutting process of iron chip core stacking process and quality standard， production process and quality standard of electromagnetic shielding.
LeganesDeterioration damage of transformer core insulation
After the test， connect the data signal contact of the automobile relay with the alarm circuit， the pull-in contact with the opening circuit， and adjust the overcurrent protection value.
Oil leakage of porcelain pot and laminated glass oil level gauge
When oil samples are used， the safety and fire safety technical specifications on the spot shall be strictly implemented.
The selection shall be carried out according to the load characteristics of power. There are many types of power loads. Different dry-type transformers shall be used for different power loads. If the standard impulse level of power load is less than kV， class H dry-type transformers shall be used. If the standard impulse level of power load exceeds kV， high-frequency vibration damping mechanical equipment， such as low-frequency vibration damping platform， is installed at the bottom of the dry-type transformer， which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings， roads， etc. with flexible connection， or use elastic yellow shock absorption mechanical equipment to prevent the vibration from spreading according to the rigid connection. If possible， the dry-type transformer room can also be soundproofed and decorated， and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.

The main reason is that the welding quality of electric welding is poor， there are empty welding， open welding， needle holes， and the potential safety hazards are exposed after operation. In addition， the electromagnetic induction vibration will crack the electric welding and lead to leakage.

When the transformer is put into operation， a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective， it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound， once the load increases， power off immediately for maintenance.
TrustworthyIn terms of the place of use dry-type transformers are mostly used in & ldquo; Fireproof and explosion-proof type & rdquo; It is easy to use in large and medium-sized engineering buildings and multi-storey buildings; The oil immersed transformer because of & ldquo; Accident & rdquo; There is likely to be oil or leakage after fire， and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;
Automatic system of centrifugal fan: measure the temperature data signal according to the PT thermistor temperature measuring resistor of the embedded parts at the hot part of the bottom pressure winding. The transformer load expands and the operating temperature increases. When the winding temperature reaches ℃，TaguergonOil immersed transformer 50KVA， the system software automatically starts the centrifugal fan for refrigeration; When the winding temperature is as low as ℃， the system software will automatically terminate the centrifugal fan.
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.
TaguergonThe plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized， the electric flow will leak into the earth along the installed grounding wires， so as to achieve the purpose of safety， otherwise it will have an adverse impact on life safety.
When the transformer is put into operation， if the tap changer is not in time， a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective， it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound， once the load increases， it is likely to burn the circuit breaker of the tap changer. In case of such situation power off immediately for maintenance.
The flange surface is uneven， 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.
