(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, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management a spacing of more than m shall be reserved; If metal fence is selected, which can control the oscillation below .%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.Shangri la town,Several detection methods for installing transformerBefore no-load impact closing, the pose period of overcurrent protection shall be set to zero, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.Boras,Oil leakage of cast iron partsBefore no-load impact closing, the pose period of overcurrent protection shall be set to zero, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.In the case of dry-type transformer operation, there is more noise and some even cause noise, which seriously endangers everyone's no problem rest time and work. At this time, the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer's network editor to simply understand it.

Overload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation which dissolve and ignite, resulting in a lot of steam bodies, greatly increasing the internal working pressure of the power transformer, causing the ignition of the casing, causing large-scale power failure, endangering all normal production, manufacturing and activities. There are three reasons for fire accidents in the operation of power transformers.Visual inspection method for transformer inspectionBefore no-load impact closing, the pose period of overcurrent protection shall be set to zero,Power transformers are also used for testing, which are called test power transformers. They can be divided into inflatable, oil transformer, dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision, It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.After the test, connect the data signal contact of the automobile relay with the alarm circuit, and adjust the overcurrent protection value.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?

Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.query,Power transformer plantThe equipment can eliminate the shortcomings found in the patrol inspection, clean the porcelain waterproof casing casing, remove and replace the cracked or brittle leather pad, check and tighten the node,Shangri la town10kV oil immersed distribution transformer, replenish the oil with less oil, check and replace the silica gel of the breathing mask, etc.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,Shangri la townHow much is a 500 KVA box transformer,Shangri la townBasic knowledge of power transformer, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).Shangri la town,The vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, it must also be changed to produce flexible connection.The noise of dry-type transformer comes fromThe key reason for oil leakage is that there are defects in cast iron parts
