11. Variable Frequency Resonant Device

 

Brief introduction

 

HZBP-BD series variable frequency resonant device is a set of intelligent equipment special for AC withstand test of commen primary electrical equipment of substations. It is applied for the capacity equipments such as transformer, GIS system, SF6 switch, CT\PT, insulator, busbar, cable and bushing ect. This decive is researched and manufactured according to withstand test regulations of 220KV and blow substations primary electrical equipment. It both can santisfy high voltage, small current and low voltage, large current test condition, with wide application range. HZBP using the principle of series resonant, is composed of variable frequency power supply control box(table), driving transformer, reactor and capacity divider.

 

Product features

 

It has smaller vollume and lighter weight compared with the same voltage and capacity reactor. Temperature rises small at the rated load. Dry-type epoxy resin casti with high mechanical strength, good electrical insolating property, nice appearance and reliability.

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

Flexible configuration. Can choose to equip with different type reactor to satisfy different tested product. To achieve a multi-purpose machine, cost effective.
