Power people: these low-voltage electrical terms you know a few?

Under the background of "Made in China 2025", the development of low-voltage electrical appliances industry will determine new technologies and new directions. The country's low-voltage electrical appliance manufacturers will face technological transformation and upgrade to further enhance the international competitiveness of domestic low-voltage electrical appliance enterprises. In the face of such a strong trend of development, low-voltage electrical appliances as a power supply "credit", how many people who are proficient in this industry jargon?

Now, follow Xiao Bian to see the power people have to be familiar with the low-voltage electrical terms it!


Low-voltage electrical terminology


On-off time: from the beginning of the current switch in a pole flow through the moment, until all poles of the arc extinguished the moment immediately before the time interval.


Arcing time: During the electrical disconnection, the time from the instant when the contact breaks (or melt blown) to the moment when the arc completely extinguishes.


Breaking capacity: the switching device under the conditions specified, can be cut off at a given voltage expected breaking current value.


Turn-on capacity: Switching equipment in the specified conditions, can be turned on at a given voltage is expected to turn on the current value.


On-off capability: the expected value of current that switches on and off at a given voltage under specified conditions.


Short-circuit-making ability: In the specified conditions, including the switch short-circuit the electrical outlet, including the ability to connect.


Short-circuit breaking capacity: under the conditions specified, including the short-circuit switch outlet short circuit, including the ability to break.


Frequency of operation: The maximum number of cycles that an electrical switch can achieve in an hour.


Power Continuity: electrical load time and duty cycle ratio, often expressed as a percentage.


Electrical life: the provisions of the normal operating conditions, the mechanical switch electrical parts do not need to repair or replace the load operating cycles.
