Analysis of common faults of oil immersed 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, so as to achieve the pressure management of oil leakage.Dobel,Transformer isFault judgment of power transformerVeenendaal,kV and above & plusmn; No load of rated voltage; Part of the circuit breaker of the tap power switch is installed in the phenolic resin insulating paper cylinder, and the insulating paper cylinder is installed on the wooden frame. The actual operation rocker is connected with the dynamic circuit breaker of the tap power switch according to the wooden insulating rod. The on load tap off power switch is insulated from the ground by the insulating paper cylinder of the power switch itself and the insulating limit.It includes the performance and main uses of insulating layer materials various insulating layer parts, component manufacturing processes and quality standards; Performance and main uses of various wires, coil inductance process of various ways of electromagnetic coil, solution process and quality standard, overall suit process and quality standard of electromagnetic coil; Main performance parameters of ferrite core, cutting process of iron chip, core stacking process and quality standard, production process and quality standard of electromagnetic shielding.For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, it is very easy to cause fire accidents, power failure, etc.

If the volume of power transformer is too small, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.Under normal conditions, different oil-based oils cannot be mixed. Under special circumstances, if it is necessary to use new oil of different grades, and then the oil mixing test should be carried out.The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.Application process,The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, it is very easy to cause fire accidents power failure, damage to machinery and equipment, etc.Oil leakage of cast iron parts

The 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.consumption,DobelModel of control transformer,Careless maintenance and insulation damageAfter the power transformer has been used for a long time, common faults of iron core will occur. Don't worry. Contact the transformer manufacturer, and the manufacturer will assign professional technicians for inspection. The main reasons are as follows:Wiring mode of dry-type transformer:Dobel,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,DobelQuotation for 2500kVA dry type transformer, 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,Dobel80 box type transformer, power off immediately for maintenance.Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin, cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil, insulated by insulating oil in the circulating system inside the transformer, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.Performance and main parameters of common metal composites, various welding processes and machinery and equipment, preparation treatment of thick steel plate, blanking process, 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.
