One、the use: The KDBX-3801 frequency conversion resonance test installment satisfies 10kV and the 35kV crossing linking polyethylene electric cable or the oak models the insulation power cable exchange compression test.

Second、the complete equipment includes: 1st, frequency conversion control box  

1、

A、Input work power source: Single-phase 220V,50Hz maximum current 24A

B、Fixed output voltage: 0~250V,

C、Output frequency: 30~300Hz, frequency control degree of fineness 0.1Hz Instability ≤0.05% specified output: The 6kW system has the high and low pressure overflow pressure, the earth, the electric discharge, the detune and the zero position and so on the automatic protection function, large screen LCD survey demonstration, parameter and function prompt, harmonious way for numeral automatic or numeral manual tuning, within the aircraft test result data preservation.

2nd, excitation transformer    1 excitation transformer is the dry transformer, between the input and the output winding is an isolated-type. According to the equipment use, the excitation changes the output for the simplex winding or the multi-windings, the output voltage distinguishes 0.75kV, 1.5kV, 3.0kV, rated capacity: 6kVA

3, resonant reactor    3 resonant reactors use when does not have to surpass its rated voltage and the electric current, under the fixed operating current does not have the overswing continuous working time. The reactor may many series or parallel. Rating highest working voltage: 18kV (effective value)

4, condenser divider      1   

a, working: Pure electric capacity type   

b, operating frequency: 30~300Hz   

c, measuring error: <1.0%

d, Output capacity: 75~1000pF±5%

5, load compensation capacitor    When is tried the electric capacity is small, may in try the both sides shunt loading compensation capacitor, causes the resonance frequency in the range of validity, or causes the resonance frequency to be lower. When use does not have to surpass the rated voltage.

6th, the appendix contains: The discharging rod and special-purpose meets the grounding, the power cable, the frequency conversion output electric cable and so on.

Second、 KDBX-3801 series resonance test equipment main performance index and characteristic:
