Q:How to test the transformer capacity
Temperature test is the main means of testing the transformer capacity. Its purpose is to assess the transformer in the rated load working state or overload working conditions, the thermal state of the transformer and so on.  
Q:Transformer is the transmission of electrical equipment
The transformer is an electrical device that converts the AC voltage level to achieve the purpose of power transmission.
Q:Will the installation of transformers, power supply bureau is how the charges?
Peak valley price, one day divided into several periods. Each local price is different, the specific local electricity price can call 95598 advice
Q:Three-phase transformer how to calculate the current, ah, the formula is?
Calculation formula and empirical formula of transformer secondary current Three-phase transformer current calculation formula I = S / (root number 3 * U), where U is the transformer line voltage, KV Transformer Current Experience Port Algorithm: Primary Current I ≈ S * 0.06 Secondary Current I ≈ S * 1.5 For example: a 500KVA transformer to calculate the current and secondary current, with the current formula I = S / (root 3 * U) I = 500 / root 3 * 10 = 500 / 17.32 ≈ 28.8AI = 500 / root 3 * 0.4 = 500 / 0.69 = 724.6A with the transformer current experience calculation formula: I = 500 * 0.06 ≈ 30A I = 500 * 1.5 = 750A Transformer operating load requirements For example: a 800KVA10 / 0.4KV transformer, according to the first and second current calculation, a variety of load current is how much? Solution: Primary current I = S * 0.06 = 800 * 0.06 = 48A Secondary current I = S * 1.5 = 800 * 1.5 = 1200A Low load: Primary current I = 48 * 15% = 7.2A Secondary current I = 1200 * 15% = 180A Reasonable load: primary current I = 48 * 50% = 24A Secondary current I = 1200 * 50% = 600A Full load: primary current I = 48 * 75% = 12A Secondary current I = 1200 * 75% = 900A
Q:Sichuan transformer manufacturer that a best?
Chengdu Tianma electronic appliances limited liability company the best quality, our company with its cooperation for more than ten years, trustworthy!
Q:Transformer three-phase imbalance which harm
There is no obvious harm to the transformer, but will limit the capacity of the transformer can not get 100% play. For example, A-phase current close to the transformer rated current, B, C-phase current only 10% of the rated current, but then the transformer can no longer take any three-phase power equipment, limiting the capacity of the transformer.
Q:How to calculate non - isolated power transformer parameters
General non-isolated auxiliary windings according to chip drop VCC operating range. T = 1 / f Dmin = Vout / Vin (max) Ton = T * Dmin Id = Io * 0.3 (0.3 for the ripple current coefficient) Inductor voltage V = Vinmin-Vout-0.6 (Schottky voltage drop) Lmin = V * dt / di If there are problems please go to the big bit of the forum electronic transformer plate
Q:What is the vacuum impregnation of the transformer?
In addition, if the conditions can also be limited if the transformer high temperature dipping (100 ~ 120 degrees), you can play the same effect
Q:What is the meaning of the transformer 'turns ratio'? what's the effect?
The turns ratio of the transformer is the ratio of the transformer, that is, the ratio of the turns of the original coil and the secondary coil. Role: reflects the original transformer, vice coil voltage RMS ratio. In the case where the no-load current is negligible, the magnitude of the original and secondary coil current is inversely proportional to the number of turns. For example, 220 volts to 10 volts voltage ratio is 220: 10, turns ratio should also be 220: 10, such as the primary is 2200 laps, the secondary should be 100 laps. Multi-turn ratio is the number of turns of the secondary output and the primary correspondence. A variety of turns ratio is to allow a sensor device is used for a variety of heat treatment process. Transformer is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, regulation (etc., according to the use can be divided into: distribution transformers, power transformers, sealed transformers, modular transformers, dry transformers, Single-phase transformers, electric furnace transformers, rectifier transformers, etc. Transformers are the use of electromagnetic induction principle to change the AC voltage device, the main components are primary coil, secondary coil and core. The main functions are: voltage conversion, current conversion, , Isolated, regulated (etc.) by use can be divided into: power transformers and special transformers. Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
Q:The specific steps and procedures for installing the transformer
Oil-immersed or dry-type transformers are generally installed by the engineering team or factory installed do not know how much capacity your transformer is electronic or industrial power system
