Q:Taiwan, Taiwan, the concept of transformer
Metering points are generally placed on the two sides of the equipment for property rights demarcation point. Some "real production boundaries" are not suitable for loading tables, the measurement points can be located in the substation, if the measurement point and production to the demarcation point is different, the asset owner should bear the loss of their own property equipment. For the substation of the various routes, the measurement point is located in the various routes on the outlet. Transformer two transformers run parallel to the situation is very common. Parallel operation can make the power quality better, and better play the potential of equipment and so on.
Q:What are the specifications of the transformer capacity?
The choice of transformer capacity has a great impact on the comprehensive investment efficiency. Transformer capacity selected too large, there "big horse car" phenomenon, not only a one-time investment, no-load loss is also large. Transformer capacity selected too small, transformer load loss increases, economically unreasonable, technically not feasible.
Q:Why the new operation of the transformer to be charged
Transformer to charge? Can I charge it? You should make a mistake
Q:Transformer input power how to ask?
Transformer Efficiency = Output Power / Input Power * 100% The input power of the transformer will be larger, and the output power is the power difference of the input power minus the loss. Or the input power of the input power transformer plus the sum of the transformer losses. If you know the efficiency of the transformer, then the input power is the transformer output power and transformer efficiency ratio. General small capacity transformer, the efficiency of about 90%, large capacity transformer, the efficiency of 98%. Each motor system consumes two power, namely the real useful work (called kw) and the reactive power. The power factor is the ratio between the useful power and the total power. The higher the power factor, the higher the ratio between the useful power and the total power, and the system is more efficient.
Q:Will the installation of transformers, power supply bureau is how the charges?
Electricity Bureau to receive construction, survey, design, equipment, measurement fees. The plane fee for the capacity of the general 250KVA above the transformer to charge capacity fee 1KVA a month generally 25 yuan. Industrial electricity is divided into peak and valley electricity price difference, agricultural electricity regardless. Details can call me
Q:Transformer Wiring and Principle
In the three-phase transformer, each core is wound around the original winding and the secondary winding, the equivalent of a single-phase transformer. Three-phase transformer high-voltage winding commonly used A, B, C, the end with X, Y, Z to represent . The low-voltage windings are represented by a, b, c and x, y, z. The high and low voltage windings can be connected in star or triangular lines, respectively. In low-voltage winding output for low voltage, high current three-phase transformer (such as plating Transformers), in order to reduce the low-voltage winding wire area, low-voltage winding also has six-phase star or six-star star connection. China's production of power distribution transformers are used Y / Y0-12 or Y / triangle -11 two standard wiring method. The number of 12 and 11, said the original winding and secondary winding line voltage difference, that is, the so-called transformer wiring group do not.
Q:Transformer if the boost and buck current will change?
According to the formula P = √3IVcosφ ,, in the case of P unchanged, V increases, I on the drop, V down, I on the rise in the case of the transformer load is constant, increase the voltage and current drop, reduce the voltage and current rise; The
Q:The difference between the reflection impedance of the ideal transformer and the hollow core transformer is different.
The reflection impedance of the hollow core transformer reflects the influence of the secondary circuit on the primary circuit through the mutual inductance. The reflection impedance is in series with the self-impedance of the primary circuit. The reflected impedance of the air-core transformer is opposite to the reactance characteristic of the secondary circuit impedance.
Q:Can the transformer oil be used as a lubricant?
Can not! Two kinds of oil indicators out of the thousands of miles out! According to you say with the line also do more money to prepare for the machine! Oh! Looking for compressor oil, general 13 # compressor oil and 19 # Compressor oil! 13 with dilute words on the 19 # must be no problem!
Q:What is the difference between transformers and inverters?
The transformer can change the voltage Inverter generally refers to the conversion from DC to AC.
