Oil leakage of bolt or pipe external thread
Oil immersed transformer company
San Juan de los Morros In fact， apart from the application of the Finance Bureau， 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.
Deterioration damage of transformer core insulation
Santiago de CubaWhen we apply oil immersed transformer， 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?
A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?
Method and process of taking oil sample of power transformer
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.
How to select dry-type transformer
The power transformer belongs to relatively durable electrical equipment，San Juan de los Morros Automatic power transmission of transformer， 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:
whereFor 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， 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.
The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core， which is stacked at the degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating which is resistant to corrosion and rust， customers must master the method of wiring. If there are problems in wiring， what is the wiring mode of dry-type transformer?
The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation， maintenance and transportation， and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.
originalTurn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank， so as to reduce the working pressure and leakage. After the leakage location is determined， appropriate surface treatment shall be carried out， and then Fushi blue raw materials shall be selected for sealing treatment.
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 ℃， 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.
The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment， the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.
San Juan de los Morros The method and whole process of taking oil sample of power transformer are as follows:
Difference between dry-type transformer and oil immersed transformer:
The input and output three-phase power lines shall be connected to phase a， phase B and phase C respectively according to the color of yellow，San Juan de los Morros Overload capacity and time of oil immersed transformer， green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage， and the grounding wire， transformer casing and its transformer point shall be connected to each other. At ordinary times， the ground wire and zero wire are led out by the neutral wire of the transformer. (for example， the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.
