KaifengTransformer power capacitanceWhat matters should be paid attention to during installation and maintenance

Noise solution of dry-type transformer

The method and whole process of taking oil sample of power transformer are as follows:

Kaifeng.The transformer manufacturer will introduce the efficiency of the transformer to you

The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.

.What about oil immersed transformer fire?

Oil leakage at electric welding position

Noise solution of dry-type transformer

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.

The top and middle of the transformer oil tank, the flange plate, resulting in insulation damage.

After no-load test run is normal for 24h, it can be transferred to on-load operation, and the load shall be gradually increased from 25% 50% and 75% by grade.

middleman.(I) the distance between the external contour of 10kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than 1m; At the angle with actual operation, a spacing of more than 2m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.

How to reduce the failure of dry-type transformer?

In specific daily life,KaifengPrice of dry-type transformer 2500, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?

The oil in the machinery and equipment of the oil storage tank shall generally stand for more than 8h before sampling; it is not necessary to stand when sampling on the running power transformer.

The cheapest.Generally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer,KaifengState Grid transformer won the bid, disconnect the switching power supply on each side, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited, the generator set must be disassembled first.

In order to better avoid overvoltage damage, a group of overvoltage maintenance high-voltage Arresters (such as y4cs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.

Overload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation, which dissolve and ignite, resulting in a lot of steam bodies, greatly increasing the internal working pressure of the power transformer, causing the ignition of the casing, causing large-scale power failure, endangering all normal production,KaifengTransformer power transmission and ignition, if the second phase is blocked there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:
