Ningbo Qiaopu Electric Co.LTD. power line industry-related terminology

Qiaopu power lines in the production process will encounter many things, such as current, voltage, power, stability, and other technical terms. Here we Ningbo Qiaopu Electric Co.LTD. met for the power cord under the profile industry related terms
1 rated current - performance under the normal conditions of use and high-voltage switchgear main circuit can carry the current value of continuous high-voltage switch equipment on test conditions.
(2) Rated voltage - the use and performance of the prescribed conditions to the maximum continuous operation voltage, and it determines
3 Rated current Breaking current - under specified conditions, the normal circuit breaker to ensure the maximum short-circuit breaking current.
4 rated frequency - the required performance under the conditions of normal use and continuous operation of the grid frequency to the value, and it rated voltage, rated current to determine the high-voltage switch equipment on test conditions.
5. Rated peak withstand current (rated thermal current) - the use and performance of the prescribed conditions, the switch in the closed position can withstand the rated short time withstand current wave of the first half of the peak current.
6 Rated short time withstand current (rated thermal current) - the use and performance of the prescribed conditions, in determining the short period of time, the switch in the closed position can carry the provisions of rms current.
7. Rated short-circuit current - voltage and require the use and performance conditions, switch to the TV to ensure the normal short-circuit breaking current peak.
8 rated operation (lightning) impulse withstand voltage - when the pressure test, the equipment insulation can withstand the operation (lightning) impulse voltage of the standard value.
9 temperature - current switching device through various parts of the temperature and the ambient air temperature difference.
10 Power Factor (loop) - Switchgear switching test circuit equivalent circuit, under the frequency ratio of resistance and inductance, does not include the load impedance.
11 rated frequency withstand voltage - the conditions and time required to test the device's frequency withstand voltage standard value (RMS).
12 rated short-circuit duration (Rated dynamic time) - in co-location switch can carry the rated short time withstand current time interval.
