BharatpurTest items of power transformerFacing increased trade friction

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,BharatpurDry type transformer production video,BharatpurHow much is a 400 KVA box transformer, 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.

Oil immersed transformer operation

Bharatpur.Several detection methods for installing transformer

When the full load test is carried out and everything is normal, the load can be connected.

.The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.

If you want to check the activated carbon fiber for the hanging cover, first take out the low-voltage waterproof sleeve and the on load transformer power switch, then lower the bell cover anchor bolt of the large cover, slowly hang the galvanized steel wire rope with sufficient lifting net weight on the commonly used earrings, wear 4 round steel from top to bottom in the surrounding screw holes, and count the spacing and specifications for easy reinstallation. At the same time, the cable wind shall be added on all sides to ensure that the core international body will not be damaged during the whole lifting process. After lifting for 100mm, stabilize the bell cover, and check the bearing capacity of the lifting core, center of gravity and Jack. After everything is normal, lift it again until the bell cover exceeds the relative height of the body, and rotate the crane to place the bell cover on the clean skid.

Power transformers are used in all walks of life

After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.

During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.

Protective measures for damping of dry-type transformer

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

Solenoid insulation deterioration

Sound in case of phase failure

The noise of dry-type transformer comes from

Service first.Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut), wipe the Fushi blue film remover on the surface, and then tighten it after wiping the raw materials on the surface. After drying, the treatment goal can be achieved.

For oil transformer oil replenishment, unused transformer oil conforming to the new standard should be selected first. In addition, the oil with the same basic, same brand and same additive type is expected to have a stronger effect. The characteristics of the oil should not be lower than that of the oil in mechanical equipment. When the new remaining oil is less than 5%, there is generally no problem. However if there is more new remaining oil, oil shall be added before oil type Chromatographic analysis and pressure test shall be carried out to establish that there is no oil stain, and the acid value and dielectric loss shall not exceed the oil in the machinery and equipment.

In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, what is the wiring mode of dry-type transformer?

Bharatpur.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.

What is the wavelength of oil immersed transformer?
