Nanyang cave6 Fault judgment of power transformer
It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials,Nanyang cavePrinciple of oil immersed power transformer, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.
Nanyang cave.In order to promote the use of energy-saving transformers, 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.
Performance and main parameters of common metal composites, various welding processes and machinery and equipment, preparation treatment of thick steel plate,Nanyang caveModel of oil immersed transformer, blanking process,Nanyang caveBox type transformer room, production and manufacturing process and quality standards of automobile oil tank, riser, coupling and oil storage tank cabinet, welding leakage test and NDT technology, surface treatment process and quality standards, copper, Production process and quality standard of aluminum shield; Body suit iron insertion process, wire installation process body dryness solution and dry transformer oil solution process, vacuum pump oil immersion, general installation process, leakage test and leakage detection process and quality standards. Performance parameters of key work clothes, machinery and equipment of each process flow; The natural working environment is basically regulated.
.Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.
For the leakage that has already occurred, find the leakage point first, which can not be ignored. For the position with serious leakage, shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage, the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation, the goal of long-term treatment of leakage can be achieved.
The tap changer of power transformer shall also have strong insulation. 10kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.
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.
Several detection methods for installing transformer
What is the wiring mode of dry-type transformer?
Development Curriculum.The method and whole process of taking oil sample of power transformer are as follows:
For no-load impulse closing of transformer, pay attention to the following matters:
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, electrical components and insulating raw materials.
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.
Total quality management.High voltage fuse of transformer breaks one phase;
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 of heat pipe radiator
Nanyang cave.In fact, ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them, safety factor grounding device can be divided into grounding protection, anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.
Before 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.
