Product Overview
TPXB-D series cable AC voltage withstand frequency modulation series resonance device adopts the way of adjusting the frequency of the power supply, so that the reactor and the test capacitor to realize the resonance, on the subject to obtain a high voltage and high current, is currently a new method of high-voltage test and the trend of domestic and international Has been widely used.
At present, the use of the cable voltage in 35kV and the following voltage level of a large number of test workload, so this type of withstand voltage test device should be small size, light weight. Therefore, our company produces the TPXB-D series cable AC voltage withstand frequency modulation series resonance device, so that the weight of each individual component of the product is guaranteed to be no more than 50 kilograms, suitable for on-site handling.
The power supply adopts 220V single-phase power supply or 380V single-phase power supply, which is convenient for on-site power supply; the reactor part adopts dry epoxy casting, which is beautiful and reliable, and is suitable for all kinds of cables. Part of the configuration can also meet the 110kV cable AC voltage withstand test.
Equipment Components
◆TPCB-B type frequency control power supply
◆EDYD series excitation transformer
◆EDDK series reactor
◆EDFC series capacitor voltage divider
◆EDC series high voltage capacitor
◆Various kinds of connecting wire
◆Access to DZCL series high-voltage rectifier silicon pile and H9840 type DC digital microammeter can complete the DC withstand voltage test of the equipment. Since the system has good filtering characteristics after resonance, the DC voltage it produces is better than that rectified from an ordinary test transformer.
Product features
◆Simple operation. Three modes of manual test (manual searching for resonance point and manual boosting), automatic tuning (automatic searching for resonance point) and automatic test (automatic searching for resonance point and automatic boosting) are adapted to different test requirements
◆Small partial discharge, high Q value and wide frequency tuning range.
◆No transient overvoltage after flash soldering.
◆The design of this device is unique. The test voltage of high-voltage combined electrical appliances is high, but the test current is small, while the test voltage of high-voltage cables is relatively low compared with that of high-voltage combined electrical appliances, but the test current is greatly increased. Therefore, this kind of FM resonance device divides the reactor into n sections, so that it can output high voltage/small current in series, and can output lower voltage/large current in parallel.
◆Can look forward to the conventional test transformer to complete the substation AC withstand voltage test, the test power supply capacity is small, for the test capacity of 1/20 ~ 1/30 times to solve the transformer with variable power supply capacity is less than the test capacity.
◆Large test range, can be CT, PT, openings, circuit breakers, insulators, bus transformer neutral point, etc. for AC withstand vibration test.
◆Light weight, single piece weight ≤ 40kg, easy to move, very convenient for ready-made test.
◆The device can test the field XLPE cross-linked polyethylene cable 220KV voltage class 1200mm2 length up to 10 kilometers.
◆Large screen display test data, status and real-time operation step prompts
◆Using our proprietary 16-bit fine FM and VM software expertise, 11KHZ carrier frequency, SPWM and imported original IPM overall module. With appropriate reactor, it can meet the frequency range stipulated by national and local power departments, and the whole machine is ahead of similar products at home and abroad.
