Definition Of Terms

1.Three-phase different period: refers to the maximum and minimum difference between the three-phase opening (closing) time of the switch.

2.Same phase and different period: Refers to the opening (closing) time difference of the same phase fracture for the switch with more than six fractures.

3.Bounce time: refers to the cumulative time value of all contact and separation (bounce) of the switch's dynamic and static contacts during the closing process (ie, the time between the first contact and full contact).

4.Opening time: the time interval from the moment of opening and tripping of the circuit breaker in the closing position to the moment when all arc contacts of each pole are separated.

5.Closing time: The time interval from the moment when the closing circuit is energized to the moment when the contacts of all poles are in contact with the circuit breaker in the opening position.

6.Reclosing time: during the reclosing cycle, the time interval from the beginning of the opening time to the time when all pole contacts are in contact.

7.Just opening (closing) speed: refers to the average speed within a specified time or within a specified distance when the moving contact of the switch is in contact with the static contact, taking 10ms as an example, it means opening for opening The average speed in the last 10ms, for closing, is the average speed in the 10ms before closing.

8.ontact between the moving contact and the static contact.

9.Maximum speed of opening (closing): refers to the maximum value of the instantaneous speed of opening (closing). Generally speaking, this value should appear in the segment just after the switch is opened or closed. This point can be judged from the speed and stroke curve.

10.Opening (closing) average speed: refers to the ratio of the stroke of the switch moving contact to the time during the entire movement process.
