Problems solved by technology

Among them, the on-site portable inductance tester has a small measurement range and low precision. It can only measure millihenry (mH) inductance, but cannot measure microhenry (μH) inductance. There is no portable microhenry inductance tester on the market. Therefore, near For several years, the micro-inductance components in the DC field of the converter station cannot be tested; only the capacitance and loop resistance in the converter station can be measured

Abstract

The invention discloses an ultra-high-voltage converter station based direct-current field micro-inductor general-purpose tester which comprises a processor, a direct-current voltage sampler, a directcurrent sampler, an AD converter, a 12C storage device, a USB flash disk processor, a touch liquid crystal display, a thermal printer and an R-type transformer, wherein the direct-current voltage sampler, the direct current sampler, the AD converter, the 12C storage device, the USB flash disk processor, the touch liquid crystal display and the thermal printer are connected to the processor; the R-type transformer is connected with an RCL test power supply and an alternating current source gear; the RCL test power supply and the alternating current source gear are connected to the processor; the RCL test power supply is further connected with a constant current source and gears and a four-terminal measuring terminal. The ultra-high-voltage converter station based direct-current field micro-inductor general-purpose tester is ingenious in structure, the capacitor, inductance and direct current resistance can be integrated, the one-machine multi-purpose effect is achieved, and field testrequirements are well and conveniently met; moreover, the test of inductance and direct current resistance is completed by virtue of primary connection, and the working efficiency of field personnel is improved.

Description

technical field [0001] The invention relates to the field of measurement technology for technical converter stations, in particular to a micro-inductance comprehensive tester based on UHV converter station DC field. Background technique [0002] There are many capacitance, inductance, and loop resistance testers on the market. Among them, the on-site portable inductance tester has a small measurement range and low precision. It can only measure millihenry (mH) inductance, but cannot measure microhenry (μH) inductance. There is no portable microhenry inductance tester on the market. Therefore, near For several years, the micro-inductance components in the DC field of the converter station cannot be tested; only the capacitance and loop resistance in the converter station can be measured. Therefore, there is an urgent need for a comprehensive tester that can not only measure the capacitance and loop resistance of the converter station, but also measure the micro-inductance co...
