No matter what we are using, we need to understand its operating specifications. Otherwise, our use will have no effect. The self-adhesive coil is the same. What are the operating specifications of the self-adhesive coil arc suppression coil?
(1) The switching or tapping of arc suppression coil of self-adhesive coil shall be adjusted according to the dispatching order of self-adhesive coil or the regulations of site regulations.
(2) The arc suppression coil of the self-adhesive coil shall be over compensated. Under normal conditions, the displacement voltage of the neutral point of the self-adhesive coil shall not be greater than 15% of the rated phase voltage, and it is not allowed to exceed 15% for a long time. The allowable value within 1h during operation is 30%.
(3) When the terminal voltage of the arc suppression coil of the self-adhesive coil exceeds 15% of the phase voltage (except during operation), the arc suppression coil of the self-adhesive coil has acted. It shall be treated as a grounding fault to find a grounding point.
(4) In the case of single-phase grounding of the system, the arc suppression coil shall not be stopped, and the self-adhesive coil shall monitor the upper oil temperature Z, which shall not exceed 95 ℃. The self-adhesive coil shall be monitored and its operation time shall not exceed the allowable time specified on the nameplate or on-site regulations. Otherwise, cut off the fault line and deactivate the arc suppression coil.
