Q:How to use a multimeter to determine the quality of small transformers
Generally with the smallest ohm file to measure whether the primary tap, if not, then damaged. Use the X10K stall above the ohm stalls to measure the primary and secondary, primary secondary and iron core for short circuit or leakage. If there is connectivity, then the insulation is bad or has been burned or breakdown.
Q:What is the impedance voltage standard of a power transformer?
35kV on-load pressure: ≥2000kVA≤2500kVA, 6.5%; ≥3150kVA≤5000kVA, 7.0%; ≥6300kVA≤10000kVA, 7.5%; ≥12500kVA, 8%; 66kV: ≤ 5000kVA, 8%; ≥6300kVA, 9%; 110 kV: double windings are 10.5%; three winding boost: high - medium 17-18%, high - low 10.5%, medium - low 6.5%; buck: high - 10.5%, high - low 17-18% , Medium - low 6.5%
Q:Transformers are divided into several. What is the role of each? To be specific!
Transformer is the instrument that regulates voltage! Transformers can be classified according to their operating frequency, use and core shape. (1) Classification by operating frequency Transformers according to the operating frequency can be divided into high-frequency transformers, IF transformers and low-frequency transformers.
Q:Question about transformers !!?
i) the secondary transformer impedance is 1.12 + j6.4Ω. Since Ns/Np 4, this impedance reflected to the input is (1.12 +j6.4Ω)/(Np/Ns)² 007 + j0.4Ω ii) Reflect the primary transformer voltage and impedance to the secondary side. 230(Ns/Np) (1.12Ω + j6.4Ω + (Ns/Np)²(0.03Ω + j0.1Ω ) +200Ω + j100Ω )I 920 (1.6 +200 + j8 +j100)I (201.6 + j108)I |Z| 228.7Ω √(201.6² + 108²) at angle of inverse tan (108/201.6) 28.18° I 4.02 amps at -28.18° 3.54 - j1.90 amps The terminal voltage is 920 - (1.6Ω +j8Ω)(3.54 - j1.90 amps) iii) solve 920 (1.6Ω +200Ω + j8Ω - j100Ω)I (201.6Ω - j92Ω)I The terminal voltage is 920 - (1.6Ω + j8Ω)I
Q:What is the principle of the conversion of the transformer? How to restore the secondary side to the primary side?
Understand P1 = P2 (no loss here). To know the return of the.
Q:How many robots will be in the transformers movie?
I, robotic has some extremely cool scuffling with scenes (witness the countless issues the robots are able to, basically superb). And unusually sufficient, Shia Laboeuf has a function in it too. i assume Shia likes his robotic video clips.
Q:A question about Transformers URGENT?
1. You haven't specified your requirement. 2. Transformers don't regulate. Regulate is the job of a voltage regulator chip, like the LM7805. 3. Transformers don't manage either. People manage. People can also program computers to manage switches. Transformers just sit there, waiting for a closed loop for current flow on both primary coil and secondary coil. When both loops are closed, energy is transferred from one coil to the other by magnetic induction. When either loop is open, current ceases in the open coil, but still creates an alternating magnetic field in the closed loop, if the closed loop is the primary.
Q:Transformer short-circuit impedance is big good, or small good? The same capacity, voltage ... solution
Transformer impedance depends on the size of many factors: 1 circuit breaker breaking capacity. Transformer below the power distribution board in a variety of electrical equipment has parameters, you should calculate the short-circuit current according to the impedance of the transformer to verify that these electrical equipment can meet the requirements, the same capacity and variable ratio of the transformer, the impedance of small short-circuit current, Large short-circuit current is small; 2 transformer connected to the large-capacity motor starting voltage. If the transformer load capacity close to the transformer capacity of 1/4 of the motor, should pay attention to check its starting voltage to meet the motor terminal voltage above 70% of the rated voltage. Impedance of the transformer itself is also a large pressure drop, more difficult to meet the requirements; small impedance transformer for the start of the pressure drop better performance; because you do not know how much the transformer capacity, it can not be the absolute conclusion, if the transformer capacity below 1000KVA , The above parameters in 4% and 6% or less, the choice of 4% better
Q:What is a transformer?
First talk about the buck, usually we use a variety of voltage, such as life lighting is 220V, industrial safety lighting is 36V, welding machine voltage also need to be adjusted, which are inseparable from the transformer, the transformer through the main and auxiliary coil electromagnetic Mutual inductance principle, can reduce the voltage to the voltage we need. In the process of long-distance voltage transmission, we need to raise the voltage to a high, in order to reduce the voltage loss, usually rising to several thousand volts or even tens of kilovolts, which is the role of the transformer.
Q:changing halogen light bulb contacts/transformer?
You are putting too much energy into the transformer. You need a circuit breaker in your circuit in order to reduce the amount of power that goes through the transformer. Because so much power is going through the transformer, it can only put out so much, so fast, and, therefore, your halogen lights are not turning it on. You can google circuit breakers or resistors, or take the lights in to any hardware store to see if they can fix them.
