1. Application
Magnetically controlledarc-suppression coil of XHDT-series (MCASC) as a new generation of arc-suppressioncoils (ASC) is developed and manufactured newly by the Dandong Xintai ElectricCo., LTD (Xintai), is mainly used in neutral un-earthed power systems of 66kVand under, compensates capacitive current produced during single phase earthingshort-circuit in the power system by using inductive current of arc-suppressioncoil, rapidly extinguishes the interrupted earth arc without restriking inorder to prevent the expansion of the scope of the accident.
MCASC is different fromordinary turn-regulation type ASC, because it achievesfast response and continuous adjustable of ASC inductance by the combination ofthe modern electronic control technology and two-stage magnetic saturationtechnology and by using the operating mode of auto-type DC excitation. By usingdynamic full compensation method, it fundamentally solves inherent conflictbetween the ideal goal of full compensation and the system virtual groundcaused by series resonance. The product has passed the Authentication of State-levelNew Product Production and the Liaoning Provincial Sci-Tech Achievement Appraisal,and is awarded the utility model patent issued by the State IntellectualProperty Office (SIPO).
2. Features
l Capacity can be adjusted continuously with the adjustable rangeof 3%~100%.
l Fast response speed：The setting time from Min. capacity to Max. capacity is less than 20ms.
l Small harmonic wave: The capacity of harmonic wave is lessthan 3% to meet the demand of harmonic wave for power system.
l Low loss: The loss is generally 0.5~0.8% of the total capacity.
3. Voltage class：6KV～66KV
4. Operating environment
l Under normal use and service:
Installation site: indoor
Altitude: ≤1000m
Ambient temperature: -25℃～+40℃
l Under special condition: it can be designed and manufactured inaccordance with the requirements of customers.
