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:In the transformer load calculation to be calculated when the fire pump
And then calculate the capacity of fire, this time part of the commonly used load fire exit, all the fire load plus fire when the important load, is the fire state capacity. In accordance with these two states, the larger capacity to select the transformer capacity! Phone typing is not easy, please adopt ~
Q:Transformers, broken, how to repair
Some of the transformer buried inside an insurance, first look at the said
Q:Can dry transformers and distribution cabinets be placed in the same room?
But do not recommend dry-type transformers and distribution cabinets in emissions The reasons are as follows: Transformer operating procedures and low-voltage distribution cabinet operating procedures are not the same. This arrangement is not conducive to operational management. If it is civil engineering, housing area is relatively tight, you can use this approach. For industrial projects, especially sewage treatment plants and other municipal projects, the new construction of the land is still relatively well, there is no need and together. Transformers high noise, high heat dissipation, and low-voltage distribution cabinet together, to consider air conditioning and ventilation and other factors. Nor energy saving.
Q:New on the transformer reported to stop, how to do,
2. The time limit for reducing the capacity of electricity shall be determined according to the application made by the user, but the shortest period shall not be less than six months and the maximum period shall not exceed two years; 3. In the period of reduction, the power supply enterprises should retain the user to reduce the capacity of the right to use. Users require the resumption of electricity, no longer pay the power supply discount; more than the time limit required to restore electricity, the new equipment or capacity should be handled; 4. In the period of reduction within the requirements of the resumption of electricity, should be five days ago to the power supply business for the resumption of electricity procedures, the basic electricity from the date of unsealed; 5. After the expiration of the user and the new equipment, capacity users, two years may not bid to reduce or suspend. Such as the need to continue to handle the reduction or suspension of the reduction or suspension of part of the basic capacity of electricity should be calculated at 50 percent.
Q:What is the M of the transformer capacity MVA?
M on behalf of trillion. MVA represents the capacity of the transformer, read as: trillion volt. The conversion unit is 1MVA = 1000KVA = 1000000VA. 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:How much capacity the transformer has
For power transformers, there are 10 20 30 40 50 63 80 100 125 160 200 250 315 400 500 630 800 1000 1250 1600 2000 2500 3150 4000 5000 6300, etc. kVA.
Q:How long does it take to restart the transformer?
(4) power failure operation, the first load side of the switch, after the power side of the switch (multi-side power from low to high stop); first pull the transformer side of the knife, after pulling the bus side of the switch. Power supply operation is reversed. (5) into the backup transformer, the device should be based on the actual location and instructions to determine the load has been taken in order to make the operation of the transformer power failure. Diagonal and 3/2 wires on the transformer, although the transformer has been out of power, but the transformer's heavy gas and differential protection action can still cause its ring side of the switch trip. Should be based on the actual situation and the site of the gas protection to change the signal location or retreat gas out. (6) station transformer does not allow long-term side by side. Can be used to cut low-pressure low-pressure side of the cutting machine, with high-pressure knife cut off the station with a transformer.
Q:Transformer winding maximum temperature at?
National standard "dry-type transformers" GB6450-1986 on the dry-type transformer temperature limit to make the provisions. 1, the dry-type transformer coil, when the use of A-class insulation material, the ultimate operating temperature of 105 ℃, the maximum temperature rise should be less than 60 ℃; when the use of E-class insulation material, the limit operating temperature at 120 ℃ , The maximum temperature rise should be less than 75 ℃; when using B-class insulation material, the extreme working temperature at 130 ℃, the maximum temperature rise should be less than 80 ℃; when using F-class insulation material, the limit operating temperature at 155 ℃ , The maximum temperature rise should be less than 100 ℃; when the use of H-class insulation material, the limit operating temperature at 180 ℃, the maximum temperature rise should be less than 125 ℃; when using C-class insulation material, the extreme working temperature at 220 ℃ , The maximum temperature rise should be less than 150 ℃.
Q:Transformer copper row selection
Selection principle of transformer copper Meet the load requirements; Transformer corresponding to the rated current in accordance with 1.1 times the overload factor to consider; To meet the safety distance, and components aligned; Satisfy the dynamic stability. Transformer copper selection considerations The choice of copper can not just consider the current carrying capacity it also consider the maximum short-circuit current size, that is, consider the choice of a copper after the most short-circuit when the short-circuit current short-circuit the size of the current matching the size of the protection (that is, Relay protection value size).
