Therefore, in the installation process of substation equipment, the lightning rod should be set according to the specific situation to prevent damage to the relay protection dry-type transformer caused by lightning. In addition, in the installation and use process of lightning rod select reasonable types of lightning rod according to the operation situation to determine that they are in the same situation. In addition, during the installation of lightning rod, please connect all routes as far as possible to prevent other faults.Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;Haldimand County,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, and the latter key is applied to the substation project route in big cities.Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.Dharan Bazar,When the transformer is out of phase,Haldimand CountyProduction technology of oil immersed transformer, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change,Haldimand CountyPower converter transformer, as in the case of the second phase. There are three reasons for phase deficiency:Oil immersed transformer companyWhen sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.

What is the wavelength of oil immersed transformer?The insulation between silicon steel sheets is damaged, resulting in overheating and melting of the iron core;After no-load test run is normal for h, and the load shall be gradually increased from %, % and % by grade.middleman,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).Power transformer plantPower transformer plant

(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.quality,Dry type transformer manufacturerThe step-up dry-type transformer refers to the instantaneous operation of voltage. At this stage, there are few manufacturers of dry-type transformer that can reasonably guarantee the instantaneous step-up in China. The step-up dry-type transformer has strong step-up capacity and good practical effect. The difference depends on that the transformer power switch without excitation regulator does not have the ability to change gear with load. Because this kind of tap power switch can cut off the whole process in a short time during the whole process of gear change,Haldimand CountyThree phase transformer 480v to 380V, cutting off the load current will cause arc burning between circuit breakers, tap power on and off or short circuit fault, so the dry-type transformer shall be powered off during regulation. Therefore, it is generally used as a dry-type transformer that is not very strict in voltage regulation and does not need to be adjusted frequently.The key reason for oil leakage is that there are defects in cast iron partsHaldimand County,Power transformer factoryCauses of fire in power transformerThe tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness
