Shanghai Cable Recycling Company's strength, service principle, fair survival, reputation guarantee, and principle of mutual benefit have won a good business reputation and the trust of many customers. While becoming stronger, we are also making our own efforts to protect and reuse the recycled second-hand materials and equipment, responding to the promotion of low-carbon living!
Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil, and iron core (magnetic core).
The main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.
According to their purposes, they can be divided into distribution transformers, power transformers, fully sealed transformers, combination transformers, dry-type transformers, oil immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, etc.
Transformer oil plays an important role in the operation of transformers and is also the core component of transformers. Transformer manufacturers are very careful and meticulous in the production and testing of transformer oil, and there are many steps involved. It can be said that there are layers of checks and step-by-step inspections. Until the transformer oil reaches the qualified level, there are about ten indicators of insulation oil, including moisture content (trace moisture analyzer), closed flash point (closed flash point analyzer), kinematic viscosity (kinematic viscosity analyzer), dielectric loss (fully automatic dielectric loss and volume resistivity analyzer), withstand voltage (fully automatic energy-saving strength tester), demulsification (demulsification analyzer), acid value (acid value analyzer), tension (fully automatic interfacial tension analyzer), chromatographic analysis (gas chromatograph), oil cleanliness (particle size counter), etc. Transformers have single formula groups according to production needs. The telephone for power transformer recycling is online.
Transformers are stationary electrical appliances made using the principle of electromagnetic induction. When the primary coil of a transformer is connected to an AC power source, alternating magnetic flux is generated in the iron core, which is represented by φ. The value of φ in the primary and secondary coils is the same, and it is also a harmonic function, as shown in the table as φ=φ msin ω t. According to Faraday's law of electromagnetic induction, the induced electromotive force in the primary and secondary coils is e1=- N1d φ/dt and e2=- N2d φ/dt. In the formula, N1 and N2 represent the number of turns of the primary and secondary coils. From the figure, it can be seen that U1=- e1, U2=e2 (the physical quantities of the primary coil are represented by subscript 1, and the physical quantities of the secondary coil are represented by subscript 2), and their complex effective values are U1=- E1=jN1 ΩΦ, U2=E2=- jN2 ΩΦ, let k=N1/N2, which is called the transformer ratio. From the above equation, U1/U2=- N1/N2=- k, which is the ratio of the effective values of the voltage of the primary and secondary coils of the transformer, equal to its turns ratio, and the phase difference between the voltage of the primary and secondary coils is π.
Second hand transformer recycling factory tells you about the testing procedure and precautions of transformer deformation winding tester:
Firstly, check if the grounding condition of the transformer is good, and all bushing leads should be disconnected.
2. Record in detail the nameplate data of the test sample and whether there are any abnormalities in the original working conditions, as well as the position of the tap changer of the test sample transformer under the current testing condition, and carefully input the test sample situation registration window.
3. Establish a sub directory of the test sample data file based on the condition of the test sample; After the test is completed, the measured data should be backed up to this directory and attention should be paid to organizing the work.
4. Data storage format: Files are stored in ASCII code format.
5. Measure the transformer that has just been taken out of operation, and try to dissipate heat and cool it down as much as possible before measurement; However, during the entire measurement process, the cooling measures should be stopped and the temperature should be maintained to avoid excessive temperature changes that may affect the consistency of the measurement results.
During on-site testing, in order to prevent accidental damage to the instrument, use the provided power isolation transformer. The transformer recycling company pointed out that in addition to the above products, the company also recycles products such as triple frequency high voltage generators and insulation oil dielectric strength testers. Our company has practical technology and an operation team to create services based on user experience for you. The perfection of service is our endless pursuit.
