LeGros moonHow much is a 50 KVA box transformer,

The tap changer of power transformer shall also have strong insulation. kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.Brief introduction of zero line of power transformerLeGros moonAt rated power, the ratio of output power to input power of transformer is called the efficiency of transformer, i.e. & ETA; Is the efficiency of the transformer; P is the input power and P is the output power.The time difference between different steps of three-phase power switch of switching power supply shall be less than ms, the closing shall be maintained by high-voltage arrester, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).Liptovsky Mikulas,There are many connection groups of dry-type transformers, and the selected structures and connections are also different. Then, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?What is the reason for the shutdown of power transformer?

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,LeGros moonThe dry-type transformer is good, the human resources traction belt shall be used as a guide.The transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment, the temperature or temperature rise must be tested by hand. The secondary equipment can be inspected by hand touch method when it is hot and vibrated.In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point,LeGros moonPower transformer specification, it will affect the whole power circuittarget,After sampling, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.

Power transformerreform,Oil leakage of cast iron partsThe rate of transformer is: n = P / pxo%, that is, when the copper loss of transformer is equivalent to iron loss, the rate is very large. Therefore, the load of transformer is: = P / PK. Fully consider the active power loss caused by reactive power in the system software during transformer operation. The load adjustment is: it can be seen from the calculation of load formula that the large rate of transformer does not occur when the load is full, Generally, it is about %, but when selecting the transformer capacity, we should select effective transformers according to the load condition and load, so as to make the transformer in the situation of economic development and achieve the goal of power saving.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.LeGros moon, which is stacked at the degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, which is resistant to corrosion and rust, and has sound insulation and noise reduction.Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, commerce, airports, tunnel construction, chemical enterprises and factories.Operation of oil immersed transformer
