1. What is rated voltage?
The effective value of phase-to-phase voltage marked by the equipment and related to some operating characteristics of the power system.
2. What is the rated working voltage between phases?
The voltage value to ensure the normal operation of electrical appliances under specified conditions.
3. What is the rated insulation voltage?
The manufacturer of complete sets of electrical equipment reminds that under specified conditions, the nominal voltage value used to measure the insulation strength, electrical clearance and creepage distance of different potential parts of the electrical equipment and its components is the large rated working voltage of the electrical equipment unless otherwise specified.
4. What is rated power
The working current value that the switchgear can pass for a long time under specified conditions.
5. What is the rated working current?
The current value to ensure the normal operation of electrical appliances under specified conditions.
6. What is DC?
Direct current refers to the current with certain direction and constant size, such as dry battery.
7. What is AC?
It refers to the current whose direction and size change with time.
8. What is current?
Under the action of electric field, the electrons in an object move in one direction regularly, forming a current. Current "I" indicates. The current intensity is numerically equal to the amount of electricity passing through the wire section in one second, usually expressed in ampere "A", A, KA, mA and uA are different units.
9. What is voltage?
Water flows only when it has water level. Similarly, in order to make the action of electric charge move regularly, there must be a potential difference at both ends of the circuit, which is called voltage, which is expressed by the symbol "U". The value is usually expressed by the volt "V", which includes V, KV, mV, uV and other units.
A power supply (generator, battery) can make the current flow continuously along the circuit, because it can make the potential difference between the two ends of the circuit generate and maintain, which is called the electromotive force of the power supply, expressed by "E"; The unit "V" is related to the size of the current, which is proportional to the voltage at both ends of the resistance and inversely proportional to the size of the resistance.
10. What is Ohm's Law?
R=U/I, where U: voltage, R: resistance, I: current, that is, the ratio of voltage and current in the circuit.
