RX27 resistor manufacturers describe how to see resistors and power
How to see resistance and power of winding resistance
The resistor and the sliding varistor are connected in series in the same circuit, and the current table is measured by the current table, and the voltage U at both ends of the resistor is measured with a voltage meter, and the resistance resistance value is calculated from r = u / i, from p = The UI calculates the power.
Wire winding resistor application
Both the wire winding resistor and the carrier regulation refers to the transformer separating switch modulus, and the difference is that the no-magnetic modulus switch does not have the ability to load the gear position, because this separating switch is in the conversion gear position There is a short-time disconnection process, and the load current will cause the contact between the contacts or short circuits, so the transformer must be powered off when the modulation is made. It is therefore generally used to use transformers that do not require frequent modes of voltage requirements. The load-bearing switch is available with load switching gear, because there is no short-term disconnection process during the modulation process, transition from one file to another from a transition resistor during the finalization process. Thereby, there is no discharge process that does not have a load current disconnect.
A transformer typically used to strictly adjust the voltage requirements.
Most substations are outdoor air insulated substations, in the substation, all devices are independently openly arranged in accordance with the connection of primary lines, and most of them are arranged in the control chamber, so this substation takes up the land area, and the environment is poor. Low reliability, high operation and maintenance cost. Gas insulated metal enclosed substation,,,, A new type of substation in research and development – modern compact substation, combining the advantages of these two substations. Hereinafter, modern compact substation and its modern microcomputer, optoelectronic, communication technology are discussed, and the technical economic benefits of this substation are analyzed.
