PatanOld box tGenerally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer, disconnect the switching power supply on each side, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited the generator set must be disassembled first.
In order to better carry out the experiment of power transformer oil,KangguduoBox type transformer 400kV,KangguduoSpot inspection standard for dry type transformer, and the oil sample for simplified experiment shall not be less than 1kg.
Kangguduo.In order to promote the use of energy-saving transformers, the Ministry of finance, the Ministry of industry and information technology and the national development and Reform Commission jointly promulgated the detailed rules for the implementation of energy-saving distribution transformers of energy-saving products benefiting the people project as early as 2012, providing subsidies of 4-30 yuan / KVA for energy-saving transformers.
Difference between dry-type transformer and oil immersed transformer:
.When using the oil sample of the power transformer in operation, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about 2kg of waste liquid stored at the bottom to clean the oil inlet, and then take the oil sample.
The hanging core of dry-type transformer is a vital part
The method and whole process of taking oil sample of power transformer are as follows:
Oil leakage of bolt or pipe external thread
Transformer manufacturers said that at this stage, China's energy-saving distribution transformer market is relatively scattered coupled with the constraints of factors such as low threshold in the field, uneven companies, lack of evaluation and specifications, and inadequate technical innovation,KangguduoPrice of 800 KVA dry type box transformer, resulting in slow marketing of energy-saving transformers.
When the transformer is put into operation, if the tap changer is not in time, a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective, it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound, once the load increases, it is likely to burn the circuit breaker of the tap changer. In case of such situation, power off immediately for maintenance.
Professional is king.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?
Falling foreign matters and piercing
Analysis of common faults of oil immersed transformer:
The project cost is different. Compared with the purchase price of capacity transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.
Quality inspection report.Operation and maintenance management of oil immersed transformer
In fact, apart from the application of the Finance Bureau, the industry has been trying to formulate and upgrade transformer commodities according to the specifications, so as to promote the improvement of energy consumption level of transformer commodities.
Oil leakage at electric welding position
Kangguduo.The hanging core of dry-type transformer is a vital part
When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
Before no-load impact closing, the pose period of overcurrent protection shall be set to zero
