San joda MadeiraDry type transformer 10 / 0.4kVWhat are the basic knowledge of

Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).(III) dry type transformers of KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than m; The distance between the electrified part and the road surface shall not be less than m.San joda Madeira,At rated power, the ratio of output power to input power of transformer is called the efficiency of transformer,San joda MadeiraTransformer power supply application, i.e. & ETA; Is the efficiency of the transformer; P is the input power and P is the output power.Solenoid insulation deteriorationHoly Louis,Oil leakage of bolt or pipe external threadIn terms of the place of use, 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;Oil immersed transformer

Brief introduction of zero line of power transformerHow is the quality level of dry-type transformer compared with foreign countries?If the power transformer stops running for more than h (if the allowable time should be reduced when the ambient humidity is & amp; gt; %), it should be insulated before putting into use, and accurately measured with a V grounding megger. The insulation resistance from the primary side to the secondary side and the ground should be ^ mfl, the insulation resistance from the secondary side to the ground should be ^ mh,San joda MadeiraLoss standard of dry type transformer,kV and above & plusmn; No load of rated voltage; Part of the circuit breaker of the tap power switch is installed in the phenolic resin insulating paper cylinder, and the insulating paper cylinder is installed on the wooden frame. The actual operation rocker is connected with the dynamic circuit breaker of the tap power switch according to the wooden insulating rod. The on load tap off power switch is insulated from the ground by the insulating paper cylinder of the power switch itself and the insulating limit.(IV) the transformer on the column shall be stable and firm and the waist rail shall be & phi; mm galvanized wire shall be wound over turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than .m.The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment,San joda MadeiraCustom power transformer, the output capacity can be increased by %.

What is the reason for the shutdown of power transformer?Good quality,The method and whole process of taking oil sample of power transformer are as follows:This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.What is the reason for the shutdown of power transformer?San joda Madeira,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 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.When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe
