Abstract
The invention discloses an arrester insulation aging test device, which is characterized in that an analog quantity processing system is connected to a MCU computing processor through an A/D process system; a storage, a timer, an I/O interface and a serial port are all connected to the MCU computing processor; and a wireless emitter is connected to the serial port. An arrester insulation aging test method comprises the steps of: collecting the leakage current of the arrester by the analog quantity processing system and sending to the A/D process system, converting a leakage current data into a digital signal and sending to the MCU computing processor by the A/D process system, recording the leakage current digital signal and time in the mode of an index change curve by the MCU computing processor, and alarming a central power control system by the MCU computing processor through the wireless emitter when the variation of the leakage current in a period of time exceeds a preset value input by the serial port. The invention has the advantages that the change rate of the leakage current can be freely defined, the central power control system can be alarmed by a wireless network and the manpower and material resources are saved.
Description
Technical field
The present invention relates to lightning arrester insulation ageing tester and method of testing.
Background technology
The aging of lightning arrester will badly influence the safe in utilization of power equipment, existing mode is that a tester is housed on each lightning arrester, need the staff to go to check on every equipment, and these data of checking leakage current numerical value that all is lightning arrester under the present case, these numerical value change amounts and time contrast can need be known just whether lightning arrester is aging.But the leakage current numerical value of lightning arrester and time are exponent function relation substantially to change, in early stage, leakage current may several years, do not have too big variation, and bigger variation will appear in extremely short time in later stage, depending merely on the mode of manual patrol record monitors, can make a lot of lightning arresters wear out and for a long time just be found, cause great danger for the normal use of power equipment.
Summary of the invention
The object of the present invention is to provide lightning arrester insulation ageing tester and method of testing, can effectively solve existing lightning arrester leakance monitoring, waste time and energy and the aging problem that can not in time find occurs at lightning arrester by the personal monitoring.
