Series resonance test device is communicated with the first selected equipment for pressure, the current electric power testing for pressure test equipment of large capacity subjects product usually adopts the variable frequency series resonance overvoltage withstand test device, because it USES the LC oscillation principle of LC, packaged equipment, can be used to complete a long cable, high voltage electrical equipment of pressure test grade, in practice, because of its simple operation, easy to carry, the advantages of widely used in electric power project in engineering commissioning, it controls the host variable frequency power supply can be flow of electricity through the AC - DC - AC conversion and output for pure sine wave, the output frequency and voltage adjustable within a certain range, is the core of the series resonance for booster test control part,

Today for site often encounter a situation could explain the cause and the screening program, so that we can test personnel at the scene to deal with these common problems

Each set of series resonance test device before leaving the factory, will pass strict quality inspection, but why the test site, the frequency conversion power booster will appear to rise not up to the phenomenon of (i.e., booster not reached set value), the following with your specific analysis to what caused the failure phenomenon,

Series resonance test device of the cause caused by wiring

Connection error, according to the principle of testing, frequency conversion power signal lines should be connected to the voltage divider acquisition signal column, if there is a connection error, will cause the booster to rise not, then you only need to according to the instructions of series resonance, the sample (s) with the correct connection of each part, can solve the problem of booster,

2. Short wires is broken, in the experiment, excitation and reactor through short wire connection, so as to ensure the normal order of the booster test, when the short connection fails, said excitation variable and reactor are not working, rose is not pressure is a normal, usually, the delivery from the manufacturer with the besides test must test line, some will be reserved, only need to replace the fault short wires, can normal booster,

High voltage test has certain risk, in the experiment, must strictly abide by the safety standards, in accordance with the equipment operation instruction of the correct operation steps, in order to avoid unnecessary trouble and danger, when the equipment malfunction, must first yi time consult professional personage, eradicate professional guidance for troubleshooting, must not blind self-confidence, free to remove the maintenance of equipment,
