Q:How much W?
1. And your material related. If the good material, high frequency loss is relatively small. You can do 15W. For example, 200KHZ switching frequency. 2. If you are on the general market, the maximum control in the following 10W. Switching frequency 50KHZ.
Q:110kv level, the capacity of about 43MVA transformer models and detailed parameters
Now 110kV transformer capacity is generally 50MVA. Models are generally SZ9, SZ10.
Q:New on the transformer reported to stop, how to do,
First, if it is the implementation of non-industrial nature of electricity, there is no need to apply for stop procedures, directly out of the transformer on it.
Q:How to understand the secondary side of the transformer
The transformer consists of iron core (or core) and coil, the coil has two or more than the winding, which connected to the power supply winding called the primary coil (a test), the rest of the winding called secondary (secondary side). The basic principle of the transformer is the principle of electromagnetic induction, now single-phase double-winding transformer as an example to illustrate its basic working principle: When the primary winding with voltage U1, the current I1 flow, in the core to produce alternating magnetic flux , These magnetic flux known as the main flux, in its role, both sides of the winding were induced potential E1, E2. Transformer two sets of coil turns are N1 and N2, N1 for the primary, N2 for the secondary. In the primary coil plus an AC voltage, the secondary coil will produce both ends of the induced electromotive force. When N2> N1, its induction The electromotive force is higher than the primary voltage. This transformer is called a step-up transformer: when N2 N2, U1> U2, the transformer is a step-down transformer, otherwise it is a step-up transformer.
Q:What is the meaning of auxiliary transformer, sub-variable and box change
box change is box-type transformer, that is, transformers and supporting the protection system, , Metering system, remote control system integrated into a box, generally used for urban district power supply, field power supply field.
Q:What is transformer reverse charging?
Transformer (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 (core). In electrical equipment and wireless circuits, commonly used as lifting voltage, matching impedance, safety isolation and so on.        When the transformer is shipped, it is determined whether it is used as a step-up transformer or a step-down transformer, and its relay protection setting requirements are specified. If the transformer is a step-up transformer, it is determined that the low-voltage side is zero-up. Such as from the high side of the anti-charge, then low side of the open circuit, due to the relationship between the high voltage side of the capacitor current will cause low voltage side due to electrostatic induction and over-voltage, easy to breakdown low-voltage winding. If you determine the normal high-voltage side of the transformer, such as from the low side of the anti-charge, then the high side of the open side, but the excitation current is large (up to 6 to 8 times the rated current). It produces the electric power, easy to make the mechanical strength of the transformer is a serious threat, at the same time, relay protection device may also hide the inrush current and malfunction.
Q:What does S11-M-500/10 transformer mean?
The first floor has been very accurate to answer my answer that M is sealed!
Q:100kVA transformer can withstand much of the current? What is its formula?
Three-phase transformer: rated capacity S = √3 * rated voltage U (line voltage) * rated current I (line current) On the subject: S = 100KVA High pressure U1 = 10 KV I1 = S / (√3 * U1) = 5.77 A Low pressure U2 = 0.4 KV I2 = S / (√3 * U2) = 144.34 A
Q:What is the maximum current of the 800KVA transformer? What is the current? Is how to calculate, ask you master
10KV / 0.4KV, 800KVA Transformer rated current is: High pressure side, I = 800 / (1.732 * 10) = 46.2A Low pressure side, I = 800 / (1.732 * 0.4) = 1154.7A Low side of the economic current is about: 1154.7 * 70% = 808.3A
Q:Transformer 1250KVA Dimensions
This is not fixed, you list the conventional products, unconventional products can be arbitrarily selected according to customer requirements. There are 300kv, 1000KV, 1100KV, 1150KV and so on
