Lightning current impact test device for intelligent voltage limiter

Abstract

The invention discloses a lightning current impact test device for an intelligent voltage limiter, which comprises a voltage regulator, a test transformer, a silicon stack, a capacitor, a wave-regulating resistor, a wave-regulating inductor, a current divider, a measuring instrument and a voltage divider, wherein the current divider and the voltage divider are connected with the measuring instrument, the test transformer is boosted through the voltage regulator, the secondary side voltage of the test transformer is rectified by the silicon stack and then charges the capacitor, the gap breaks down after the charging is completed, the intelligent voltage limiter is discharged through the wave-regulating resistor and the wave-regulating inductor, the actual current and residual voltage passing through the intelligent voltage limiter are measured through the measuring instrument, and the measured waveform is compared with the waveform monitored by the intelligent voltage limiter. The lightning current impact test device can verify the reliability of the intelligent voltage limiter.

Description

technical field [0001] The invention relates to an intelligent voltage limiter. Background technique [0002] For distribution line insulators, the power supply department spends a lot of manpower, material resources and time on inspections every year. Check the operation of facilities and equipment such as insulators and lightning arresters. Sometimes it is necessary to increase night inspections to check zero-value insulators. The original means of observing the discharge situation with the naked eye and listening to the discharge sound are used to operate, and the effect is extremely unsatisfactory. Only then did the problem emerge. [0003] The current lightning protection insulator itself still needs to be checked through manual inspection if it is damaged due to a fault or whether it has been struck by lightning. Intelligent voltage limiter products can automatically monitor the situation of self-failure or lightning strike. However, how to detect the effectiveness ...
