(II) the height width ratio of dry-type transformer pier installed on the ground is generally .m, and a guardrail of no less than m shall be installed around it, and a warning sign shall be hung at a prominent position.The zero line is mainly used in the working circuit. The voltage caused by the zero line is equivalent to the line resistance multiplied by the current of the working circuit. Because of the distance, the voltage caused by the zero line can not be ignored. As a countermeasure to maintain life safety, it is more and more unreliable. Ground wire (PE): it is not used as a working circuit, but only as a maintenance line. Use the affirmation of the earth & ldquo; ” Voltage. When the machine and equipment casing is electrified, the current will be quickly grounded. Even if there is a lead for the PE line, it will be grounded from the surrounding grounding body.Tara,The person in charge of a transformer manufacturer said that because of the hazards of raw materials and other factors, the cost of energy-saving transformers is significantly higher than that of traditional transformers, the market has not yet fully operated.After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.Ash Shamiyah,The hanging core of dry-type transformer is a vital partThe technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ Ω, The resistor is generally more than & omega;, According to Ohm's law when the insulating layer is damaged, the current is only / of the total current flow, so as to play a guarantee effect. The higher the voltage, the smaller the resistance, in other words, phase B and phase C respectively according to the color of yellow, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire, transformer casing and its transformer point shall be connected to each other. At ordinary times, the ground wire and zero wire are led out by the neutral wire of the transformer. (for example, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.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 kV and kV. 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, and the latter key is applied to the substation project route in big cities.Gradually,TaraPrice of scbh15 series dry type transformer, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer, which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings, roads, etc. with flexible connection or use elastic yellow shock absorption mechanical equipment to prevent the vibration from spreading according to the rigid connection. If possible, the dry-type transformer room can also be soundproofed and decorated, and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.Statistics, dry-type transformers are mostly used in & ldquo; Fireproof and explosion-proof type & rdquo; It is easy to use in large and medium-sized engineering buildings and multi-storey buildings; The oil immersed transformer because of & ldquo; Accident & rdquo; There is likely to be oil or leakage after fire and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;(I) the distance between the external contour of kV 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 m; At the angle with actual operation, a spacing of more than m shall be reserved; If metal fence is selected,TaraRecovery price of dry-type transformer, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?

Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.plan,The key reason for oil leakage is that there are defects in cast iron partsWhat is the cause of power transformer core failure?Under normal conditions, the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation, the operation and maintenance management staff shall improve the safety inspection range of the transformer, and immediately communicate and contact with the on-site project staff in case of any problems, so as to ensure the reliable and stable operation of machinery and equipment.Tara,TaraMaintenance system of oil immersed transformer,Solenoid insulation deteriorationWhen oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.After tightening the loose bolts, 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.
