Term Definition

1. Time:

From the moment to the joint (sub) gate instructions to play all the pole contacts are (separate) instantaneous time interval

2. Synchronicity:

The maximum time difference between the contact (separation) of the contact between the cutouts.

Bounce time

Switch the movable contact and the stationary contact in the closing (sub) gate operation, from the first close (separate) to the last stable to close (separate) time.

4. Operation time: (contact action time)

From the received (sub) gate instructions instantly play the moment just touch the moment.

5. Bounce times:

Switch the movable contact and the static contact in the sub (joint) gate operation, the number of separate (closed).

6. Bounce range:

The maximum bounce value of the movable contact during the movement of the movable contact.

7. Stroke:

Minute, closing operation, the distance between the starting position of the switch moving contact and the position of any one of the positions.

8. Open distance:

The total clearance between the contacts of the switch and any of the conductive parts connected thereto.

9. Super-trip:

Closing operation, the switch contacts contact the moving contact to continue the movement of the distance.

10. Travel:

Points, closing operation, the switch movement of the movement during the maximum stroke and the stability of the distance after the difference.

11. just the (minutes) speed:

Switch joint (sub) gate process, the movable contact and the static contact contact (separation) instantaneous movement speed

12. Average speed: switch together (sub) gate operation, the dynamic contact in the course of the movement of the stroke and the ratio of time.

13. gold short time:

In the combined operation, the time interval is separated from the moment when all the contacts are in contact with each other.

Sensor selection

7.1 linear resistance sensor (CWY30-2K type) linear displacement: 1-33mm

Applicable to: Vacuum circuit breakers

Distance range: <33mm error: 0.1mm

7.3 Auxiliary contacts

Auxiliary contact installation:

(1) auxiliary contact; must be installed in the switch on the moving end of the mouth or in the switch on the movable end of the trigger.

(2) the role of auxiliary contacts; is used to record the closing start and sub-gate of the time.

7.4 Points to note when installing:

(1) the contact between the axis of contact and the axis of the coaxial axis error ≤ 0.2mm.

(2) try to use the middle position of the sensor to determine the location of the contact, so that the movement of the moving stroke included in the stroke of the slider, so that the slider up and down when leaving a buffer margin.

(3) the installation to be tight and reliable, in the test so that the sensor body and the switch body can not produce relative displacement.

(4) sensors are precision electronic equipment, all parts must pay attention to waterproof and dustproof, try to keep dry and clean.
