Operation and maintenance management of oil immersed transformer
In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word if there is any problem at a certain point, it will affect the whole power circuit

Due to careless transportation of the transformer and the thin high-voltage conductor, if the oil immersed transformer catches fire, please don't panic. I firmly believe that the damage will be reduced to a lower level as long as the above methods are effectively rectified. Above is the general process and process that should be paid special attention to in the whole ignition process of the oil immersed transformer. When the oil immersed transformer catches fire, please be rational to make the oil immersed transformer safer and more efficient.
The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness, resistance to short-circuit faults, common faults and impact. The work is diligent.
In fact apart from the application of the Finance Bureau,OluPower transformer calculation sheet, the industry has been trying to formulate and upgrade transformer commodities according to the specifications, so as to promote the improvement of energy consumption level of transformer commodities.
What is the important role of power transformer
Safety production.The 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.
For 630kVA 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.
Equipped with a temperature controller,OluCharacteristics of oil immersed transformer, platinum thermistor (pt10) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer, stop the cooling centrifugal fan, set up common problem alarm, overtemperature alarm and overtemperature tripping effect, and provide reliable overvoltage protection machinery and equipment for the dry test transformer, so as to test the safety performance of the transformer operation.
The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.

Right, as & ldquo; Great Lars car & rdquo;, After replacing one 255kva small transformer, the utilization rate is close, but the main parameters of the two transformers are evaluated as shown in Table 1. Table 1 evaluates the main parameters of the transformer: capacity (VA) iron loss (W) copper loss (W). Firstly, the output power is saved according to the customary calculation method (ignoring copper loss): the results show that the loss of large capacity transformer is lower than that of small capacity transformer, It actually consumes electromagnetic energy.
There are many connection groups of dry-type transformers, and the selected structures and connections are also different. Then, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.

Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core, 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, 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.
