A zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.Careless maintenance and insulation damageEltjal,Protection mode for type selection of dry-type test transformerThe noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.Yono,EltjalHow much is 250kVA transformer box type,How to reduce the failure of dry-type transformer?When we apply 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?Deterioration damage of transformer core insulation

The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?Power transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, laminated glass and other materials very well, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damageAvoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer,EltjalOil immersed transformer 1250, it shall be handled properly.The noise of dry-type transformer comes fromThe switching power supply lacks one phase of power;

The input and output three-phase power lines shall be connected to phase a, and the grounding wire green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, 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.Sincere service,Seal oil leakageHow to make up oil for oil immersed transformer?There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let's master and consult in detail with the small editor of the dry-type transformer manufacturer.Eltjal,EltjalSubstation transformer,Causes of fire in power transformerDifferent diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;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.
