Cet article aide à planifier un laboratoire d’essai AC 150kV à 250kV pour fabricants d’isolateurs.
Source facts used
- 150kV/50kVA AC voltage test system is described for 33kV glass, porcelain and polymer insulators.
- 250kV/100kVA AC test system is described for 11kV to 66kV glass, porcelain and polymer insulators.
- IEC 60060-1:2010 and IEC 60060-2:2010 are listed as applied standards.
- Both examples use single-phase 50Hz output and 1000:1 voltage turns ratio.
- 150kV system output current is listed as 0.333A; 250kV system output current is listed as 0.4A.
- Protective resistor examples list 5kΩ rating; capacitive divider examples list 300pF±2%.
Selection guidance
La tension, la puissance kVA, le courant, les essais secs ou humides et la marge de sécurité doivent être confirmés avec les échantillons.
Acceptance and quality checks
Transformateur, résistance, diviseur, commande, mise à la terre, interverrouillage et rapports doivent être traités comme un système.
Buyer checklist
- Voltage class and maximum test voltage
- Required kVA and output current
- Dry/wet/flashover/withstand test requirement
- Transformer, resistor and divider placement
- Control room or console location
- Grounding, fencing and interlock plan
- Report and commissioning requirement
FAQ
Should the buyer send drawings first?
Yes. Drawings and standards prevent fixture, capacity and layout mismatches.
Can one system cover several product families?
Often yes, but voltage, load, fixture, chamber and report requirements must be checked together.
