HZBP-BD Variable Frequency Resonance Test System

Application:

HZBP-BD series variable frequency resonanttest system is a common primary electrical equipment of substations. It is applied forvoltage withstand test ofcapacitiveequipment, such as transformer, GIS system, SF6 switch, CT/PT, insulator, busbar, cable and bushing ect. This device is researched and manufactured according to withstand test regulations of 220KV and blow substations primary electrical equipment.The AC/DC voltage withstand test equipmentbothneed satisfy high voltage, small current and low voltage, large current test condition,andwith wide application range. HZBP using the principle of series resonant, is composedbyvariable frequency power source control box(console),excitation transformer, reactor and capacitive voltage divider,compensating capacitor.

Features:

◆It has smaller volume and lighter weight compared with the same voltagegradeand capacity reactor. Temperature rises small at the rated load. Dry-type epoxy resin castingwith high mechanical strength, good electrical insulating property, nice appearance and reliability.

◆Variable power source control box has large capacity, strong protection function, good output wave, good stability and various working modes that easy to operate. Single phase 220V and three phase 380Vinput powersourceare in common use, convenient to takeelectricity on site.

◆Flexible configuration. Can equip with different types of reactor to satisfy different tested products. To achieve a multi-purpose machine,highlycost effective.
