BetareoaPrice of 1250kva dry type transformerWhat is the benefit if you complete the work in one go?

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.

Due to poor sealing, generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.

Betareoa.When the output power P2 of the transformer is equivalent to the input power P1, the transformer will not cause loss. But in fact,BetareoaTransformer distribution room, there is no such transformer. The electromagnetic energy of transformer always causes loss. The key of this kind of loss is copper loss and iron loss. Copper loss refers to the loss caused by the number of turns of transformer coil. When the current has a fever according to the number of turns of the coil, part of the electromagnetic energy changes into energy and is lost. Because the electromagnetic coil is generally wound by copper core wire with insulating layer, it is called copper loss.

Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below 0.2%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.

.Careless maintenance and insulation damage

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.

& ldquo; YN, D11 & rdquo;, in which 11 indicates that when the working voltage phasor of the primary side line, as the minute hand refers to the position at 12 o'clock,Betareoa800 dry type transformer quotation, the phase voltage phasor of the secondary side is at 11 o'clock. That is, the phase voltage UAB of the secondary side lags 30 degrees behind the working voltage uab330 of the primary side line (or 30 degrees ahead).

The flange surface is uneven, 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.

Wiring mode of dry-type transformer:

total cost.Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin, insulated by insulating oil in the circulating system inside the transformer, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.

(III) dry type transformers of 315KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than 5m; The distance between the electrified part and the road surface shall not be less than 5m.

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.

Energy costs.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, common faults and impact. The work is diligent.

Relevant responsible persons of the transformer Federation of China Household Appliance Industry Association show that the development prospect of transformers in China in the future is still the development trend of environmental protection, low noise, fire safety and explosion-proof and high reliability. There are two key development prospects: one is the development trend of high voltage and high voltage, especially 750kV and 1100kV. The second is the development trend towards environmental protection, energy conservation and miniaturization. The former key is applied to the long-distance substation project route,BetareoaOil immersed transformer foundation, and the latter key is applied to the substation project route in big cities.

The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of 0.5kg or 1kg. 2-3 bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, source, sampling date, sampling person, weather conditions and other materials of the oil sample.
