Q:How much W?
Ee22 how much of the transformer can be related to the material used. If the material is good, high frequency loss is relatively small. 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). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
Q:What is the role of the pebbles in the transformer base
Accident oil pool. Linyi pebble production base. Specializing in the production and sale of transformers mats pebbles.
Q:What are the malfunctions and abnormal operation of the transformer?
Transformer failure: can be divided into the tank failure and tank failure. Fuel tank failure: a short circuit between the windings, short-circuit between the turns, direct grounding system side winding short circuit. Outside the tank failure: There is a short circuit between the casing and the lead wire and the ground short circuit (direct grounding system side). Transformer is not working properly: there are external faults caused by over-current, overload, oil level and due to over-voltage or frequency caused by over-excitation and so on. Line fault: phase short circuit (including three-phase short circuit, two-phase short circuit), two-phase ground short circuit, single-phase ground short circuit, transmission line disconnection.
Q:Transformer oil filter method
2, vacuum oil filter to ensure that there is a certain number of power, taking into account the size of your transformer, oil pillow position level, the oil filter is too small may not go oil cycle 3, the oil circulation from the oil pillow on the opening of the valve, where the best open after the bandaged, to prevent other debris in the filter oil fall into the transformer oil pillow. 4, filter oil after a certain time, take oil samples. Qualified to stop the oil filter, add the oil inside the oil can be closed after the oil pillow upper check valve. The transformer can be powered by one night after standing.
Q:1000KVA transformer power loss is how much
It depends on its kind of transformer oil-immersed transformer or dry, 1000KVA dry-type transformer no-load loss of about 1.5% to fill the load loss of 3%, oil-immersed transformer no-load loss of about 3% to fill the load loss of 5% The above is just for reference, because each manufacturer has a difference.
Q:630KVA transformer can use the maximum number of power appliances
No additional measures in the case, 630KVA transformer can use the maximum 420KW power appliances. 1, the transformer power factor is generally 0.8 (also 0.7), then, the total power transformer = 630 * 0.8 = 504KW. 2, according to the "power engineering design manual", the transformer capacity, for a smooth load of a single transformer, the load rate is generally about 85%, so the upper case, with electrical power = 504 * 85% = 428.4KW. 3, if it is a single high-power motor, starting current as large, even if the measures, but also a corresponding reduction in electricity consumption. 4, if the three-phase imbalance, but also a corresponding reduction in electricity consumption.
Q:What are the ways of protecting the transformer?
First, the gas protection: to protect the transformer internal short circuit and oil surface failure. Second, differential protection, current quick-break protection: to protect the transformer winding or lead-out phase of the phase-to-phase short circuit, large ground current system grounding short circuit and winding turn short circuit. Third, over-current protection: to protect the external phase short circuit, and as a gas protection and differential protection (or current quick-break protection) backup protection. Four, zero sequence current protection: protection of large ground current system external single-phase ground short circuit. 5, overload protection: to protect the symmetrical overload, only acting on the signal. Six, over-excitation protection: to protect the transformer over-excitation does not exceed the allowable limit.
Q:TN-S system in the transformer side pe line and n-line neutral point how to take
TN-S way power supply system It is the work of the zero line and dedicated protection line PE strictly separate power supply system, N line and PE line in the transformer working ground once separated, not to re-connect. Called TN-S power supply system. The TN-S power supply system is characterized as follows. 1) When the system is running normally, there is no current on the dedicated protection line, but there is an unbalanced current on the working zero line. PE line to ground no voltage, so the electrical equipment metal shell connected to zero protection is connected to the dedicated protection line PE, safe and reliable. 2) The working zero line is used only as a single-phase load circuit. 3) Dedicated protection line PE is not allowed to break, but also not allowed to enter the leakage switch. 4) the use of leakage on the trunk protection, the work of the zero line shall not have repeated grounding, and the PE line has repeatedly grounded, but not through the leakage protection, so TN-S system power supply lines can also be installed on the leakage protection. 5) TN-S power supply system is safe and reliable, suitable for industrial and civil construction and other low-voltage power supply system. In the construction work before the "three links and one leveling" (Dentsu, water, road and ground level - must use TN-S way power supply system.
Q:Rectifier and rectifier transformer
First of all to clear their own concepts to distinguish. 1. Transformers, Narrow concept: the concept of power transformers is able to electromagnetic coupling by a certain type of alternating energy into another standard alternating energy, such as voltage and current conversion, but in any case, the energy is conserved; General concept: any equipment capable of transforming can be a transformer; for example, switching power supply, resistance step-down, three-terminal regulator, and so on; 2. Rectifier, Rectification is the process of turning the alternating signal into a DC signal. The rectifier is a device that can turn the alternating signal into a DC signal. 3. Then look at the difference, Rectifier as mentioned above, the AC signal into a DC signal; For example, you can use a rectifier (rectifier bridge) to convert the mains 220V 50Hz AC into 308V DC; Rectifier transformers, that is, in the "AC into DC" can also be voltage conversion, for example, can be reduced after the rectification of 308V into 5V, 9V, 12V, or boost into 400V, 450V, 500V, or other you Want the voltage. Of course, here the transformer to do a broad understanding, because your voltage has been rectified DC voltage.
Q:Transformer capacity unit KVA?
What is the difference between kv, kva and mva? The kilovolt ampere (kVA) is the power measurement standard that is 1 kilovolt ampere. KVA is equivalent to the current in a circuit generated by the voltage of that line, usually measured in the transformer, that is he is a current unit. And kilowatts refers to the power of an electrical, that is, the power of the unit. The rated capacity represents the guaranteed value of the transformer output power under rated operating conditions and is the apparent power of the transformer. That is, the maximum output power of the transformer capacity, the transformer can not be the actual output power and capacity to be confused. The units are voltammetry (VA), kVA, and MVA.
