Product Description

I.Product Description:
HZBP-BD series variable frequency resonant device is a common primary electrical equipment of substations. It is applied for voltage withstand test of capacitive equipment, 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 equipment both need satisfy high voltage, small current and low voltage, large current test condition, and with wide application range. HZBP using the principle of series resonant, is composed by variable frequency power source control box(console), excitation transformer, reactor and capacitive voltage divider,compensating capacitor.

II.Product Features:
1.It has smaller volume and lighter weight compared with the same voltage grade and capacity reactor. Temperature rises small at the rated load. Dry-type epoxy resin casting with high mechanical strength, good electrical insulating property, nice appearance and reliability.
2.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 380V input power source are in common use, convenient to take electricity on site.
3.Flexible configuration. Can equip with different types of reactor to satisfy different tested products. To achieve a multi-purpose machine, highly cost effective.
