Power transformer plant

Takavano.Oil sample inspection & mdash; & mdash; the performance parameters such as compression resistance and residue shall be carried out every three years. The long-term overload or overload of the transformer can reduce the cycle time.

For the leakage that has already occurred, find the leakage point first, which can not be ignored. For the position with serious leakage, shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage, the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation, the goal of long-term treatment of leakage can be achieved.

.Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.

Oil leakage of heat pipe radiator

High voltage fuse of transformer breaks one phase;

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.

Transformer inspection nose sniffing method

(II) the height width ratio of dry-type transformer pier installed on the ground is generally 0.5m, and a guardrail of no less than 7m shall be installed around it, and a warning sign shall be hung at a prominent position.

Affordable price.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 D (or D) is triangular wiring.

The flange surface is uneven,TakavanoInsulation grade of power transformer, 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.

Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube,TakavanoModel and specification of power transformer, carry out it twice, samples shall be selected according to 5% of the number of gasoline barrels, but not less than 2 barrels. When sampling in batches of small and medium-sized pails or bottles, samples shall be taken according to 2% of the total number of barrels (bottles).

Pursuit of excellence.When checking the hook core, the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, if you work again, turn on the photo flash when it's light, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance, experts can inspect special tools parts, insulation,TakavanoPicture of dry-type transformer grounding wire, etc. and deliver them after they are determined to be complete and reliable.

The dry-type transformer used for power plant voltage transformation is different from the oil transformer. It is strictly prohibited to lead the way at the bottom voltage side to prevent the insulation layer of the dry-type transformer from penetrating due to overvoltage caused by overvoltage at the power grid side or lightning stroke on the line.

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.

Takavano.Oil leakage of cast iron parts

When the screw of the through core extruder holding the iron core of the transformer is loose, 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, oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.

and can be solved until power failure.

The heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding
