Krasnoyarsk220Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.
Before no-load impulse closing, the transformer shall be placed for 24h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.
Las Matas de Farfan.During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.
After the oil is drained, all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack, and the lifting point shall be on the common earrings or bolts. If necessary the human resources traction belt shall be used as a guide.
.If you want to check the activated carbon fiber for the hanging cover, 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, stop the lifting, 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.
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, resistance to short-circuit faults,Las Matas de FarfanAdvantages and disadvantages of oil immersed transformer, common faults and impact. The work is diligent.
Sound in case of phase failure
Noise pollution control and prevention measures of dry-type transformer
Dry type transformer is a common electrical equipment, which can be used to convert the alternating voltage of one standard value into another standard value of the same frequency. The step-up dry-type transformer is used to convert the low-grade alternating voltage into another high-grade alternating voltage of the same frequency. It is widely used in high-frequency industries, such as variable frequency power supply.
Oil immersed transformer operation
Sales Department.Naturally, if the oil immersed transformer catches fire, please be rational to make the oil immersed transformer safer and more efficient.
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.
(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.
Power transformer
Free consultation.Protective measures for damping of dry-type transformer
Dry type transformer, a static electrical equipment, is used to change the AC current (current) of a certain standard value into another or several types of working voltage (current) with the same frequency and different standard values. According to the supervision sampling inspection data of the third quarter of last year released by AQSIQ, among the 29 kinds of dry-type transformer commodities manufactured by 29 manufacturers in 12 provinces and municipal districts across the country, with a compliance rate of 80%& ldquo; This result mostly shows the quality level of China's dry-type transformer industry at the present stage.
It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain,Las Matas de FarfanPower tube, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.
Las Matas de Farfan.When we apply oil immersed transformer,Las Matas de Farfan160KV 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?
The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of 2-5A / Min2.
& 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, 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).
