Note:
In order to prevent electric shock, the motor and frequency converter must be
grounded before use.

• Do not install the incoming capacitor or surge suppressor, radio noise filter
to the output of the frequency converter. This will lead to the failure of the
frequency converter or the damage of the capacitor and surge suppressor. If any
of the above equipment has been installed, please remove it immediately. When
it is necessary to set a non fuse circuit breaker at the output end, please
consult the manufacturer for the selection of non fuse circuit breaker.

• With regard to electromagnetic wave interference, the input / output (main
circuit) of the frequency converter contains high-frequency components, which
may interfere with the communication equipment near the frequency converter
(such as AM radio). Therefore, EMC filters are installed to minimize
interference.

• For details of peripheral devices, please refer to the user manual of each
option and peripheral device.

• PM motor cannot operate on power frequency power supply.

• Because PM motor is a motor with built-in permanent magnet, even when the
power supply of frequency converter is disconnected, as long as the motor is
still rotating, high voltage will be generated at the motor terminal. When the
output switch is closed, turn on the power supply of the frequency converter

Q: I haven't seen Dark of the Moon, but I recently got OBSESSED with Transformers. Please don't spoil anything, but I'm curious, how do they incorporate the new chick, Rosie, Huntington-Whitely, in the movie? Do they ever explain where Micheala went(Btw- I KNOW what happened to Megan in real life.that's not what im asking lol) So yeah, thanks!Bq: SAY OPTIMUS PRIME IF YOUR A GIRL TRANSFORMER FAN:)Bq: Do MOST girls like Transformers, or is it mostly guys who like it?: The movie explains that Micheala dumped Sam. Harley is Sam's new girlfriend. BQ: OPTIMUS PRIME! BQ: I know plenty of girls who like Transformers!

Q: How can we figure out which side of transformer is primary which one is secondary by measuring resistance ? I know that the side where input or supply is provided called primary from where the output is collected is called secondary side in both step-up step down transformersAnd, how can we troubleshoot a bad or a good transformer by measuring its resistance on both sides i.e. primary side secondary side ?thanks: While you can try measuring winding resistance on both the primary and secondary sides of a transformer with a digital voltmeter or an older volt ohm meter, the value is so low a fraction of an ohm most meters can't measure it correctly. What you can do is look for different wire sizes, the step down transformer will have larger diameter wires on the secondary side of the transformer ( smaller AWG) than on the primary side (larger AWG). A step up transformer will have larger diameter wires (smaller AWG) on the primary than the secondary. Again it is almost impossible to use an ohm meter to determine if either the primary or secondary winding is shorted. This is most likely found by applying power to an unloaded transformer and measuring the excessive current draw.

Q: If you're a transformers fan, who do you think were top 10 strongest Autobots in the whole transformers universe? I mean strongest of the strongest, most brutal and powerful?lol.: TFC transformers cybertron 1: Primus (if he counts as an autobot) 2: vector prime (in his prime/glory days) 3: TFC metroplex 4: TFC quickmix 5: TFC optimus prime 6: TFC jetfire 5: TFC wingsaber 6: TFC landmine 7: TFC red alert (reborn) 8: TFC scattershot (reborn) 9: TFC hot shot (reborn) 10: TFC leobraker TFC totally dominates this list since they are the only version of transformers that can annihallate galaxies.

Q: I am learning about transformers and one of the items to calculate is the impedance. I need to calculate regular 60 Hz Core and Coil Shell Type Transformers Al wire in secundary, Cu Wire primary and use Epoxy paper for insulation.: It's pretty difficult to calculate the impedances (there's more than one) entirely from the transformer's design data. It's easier and more usual to decide on an equivalent circuit (there are plenty available depending on how well you want to model the transformer) and then to determine the parameters by a mix of calculation and measurement. A pretty basic equivalent circuit which refers all impedances to the primary side, has the primary terminals connected first by Xm and Rc in parallel (the magnetising reactance and core loss resistance) and then by a third parallel branch containg a series connection of leakage reactance Xl, winding resistance Rw and an ideal transformer of turns ratio Np/Ns. Xm is best obtained from an open circuit test but could be calculated as the inductance of the primary winding. For the latter you'd need to know core dimensions, number of winding turns and the magnetising characteristic of the core iron. If you have conductor sizes and conductivities you can calculate the winding resistance Rw, referring the secondary part to the primary by multiplying it by (Np/Ns)?. You can deduce Rc from the losses measured on open circuit at nominal voltage and Rw from dc resistance measurements on the windings. If you know the specific hysteresis and eddy current losses of the core material, you can also have a good stab at calculating Rc. The leakage reactance is quite difficult to calculate from first principles - even designers usually resort to some empirical factors. Basically it's determined from the short circiut test which is at nominal secondary current. The ratio of primary volts to secondary surrent (referred of course) on secondary short circuit will get you close to Xl - you can adjust for Rw which can be determined from the losses on short circuit (core losses are absent here!) or by the two methods indicated above. It's normally Xl that's referred to as the transformer reactance and together with Rc and Rw, the impedance.

Q: I like to construct an autotransformer . Input voltage .240Vsingle phase. to use in a system whose operation voltage is 120v. 15 amps 1000 watts can some suggest me as to how i should proceed in calculating size of core ,winding turns, wire sizes etc , now i have 4 inches square E type transformer core . I removed all windings from it. It was used in a microwave .: You are very much over-complicating the problem. All you need is to get an 18-volt transformer and design a 15 volt voltage regulator circuit based on it. Radio Shack has lots of books, parts, and resources to get you going. Also, check your local public or college library for electronics books. Have fun!

Q: Hope to engage in the transformer predecessors to answer. I hope you help me introduce a little more recommended information better: Oil-immersed power transformer is one of the company's leading products, the original Ministry of Machinery Industry planning in Shandong Province, 220kV and below the production of the only key power transformers. Product voltage level 6 ~ 220kV, capacity 30 ~ 360000kVA, including 23 series, more than 200 varieties, more than 1,400 kinds of specifications, the technical performance indicators all meet the national standards and the International Electrotechnical Commission standards. The company has designed and manufactured the first domestic 110-kilovolt 31500 kVA three-coil aluminum transformer. Since the 1982 production of 220kV transformer, the product has been used in sunshine, Taizhou, Jiangxi and many other national key projects

Q: The total power of 590kw, this transformer can bear it? It is best to give a formula, do not copy the.: 630KVA transformer generally according to the efficiency of 0.8, about 504KW load, the capacitance compensation will increase the power factor to 0.95, the load power also increased with about 590KW near the existing total power 590kw should be installed capacity, the actual load should Less than 90% can load. 630KVA Transformer rated current: I = P / 1.732 / U = 630 / 1.732 / 0.38 ≈ 957 (A) The total installed power of 590kw, load rate or full load rate of about 0.9, the capacitance compensation to the power factor increased to 0.95 when the average power factor of about 0.9, the load current: I = P × 0.9 / 1.732 / U / COSφ = 590 × 0.9 / 1.732 / 0.38 / 0.9 ≈ 896 (A) 300kw load current (when COSφ is 0.8): I = P / 1.732 / U / COSφ = 300 / 1.732 / 0.38 / 0.8 ≈ 570 (A) Large cross-section copper wire per square safe current carrying about 2.5 ~ 3A, need to wire cross-section: S = 570/3 = 190 (square)

Q: Transformer winding maximum temperature at?: From the heat point of view, each part of the winding are the same, the maximum temperature of the transformer winding in the worst part of the heat dissipation, generally in the middle of the inner winding.

Q: I have a 34kv/380/500KVA transformer and it loads a pump of 450HP/2200V. Starting current reaches up to 1700 amps for around 3-4 seconds using a soft starter. The rated capacity of the transformer is 700amps and the pump running current is 689 amps.Any calculations to prove that the transformer is enough to provide the application would be a help.thanks.: Damn, had to read the question before I realized it has NOTHING to do with Optimus Prime or Megatron.
