Max Capacity 1000kA Variable Frequency AC Resonant High Voltage Insulation Tester
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.
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.
