Abstract
The invention provides an instrument for lightening arrester monitor test. The invention has the following key technology: synthesizing the current test function and a counting function into a circuit, the function is selected through a current/counting function selecting switch for respectively completing the current test and the counting function test; the current/counting function selecting switch is connected with a discharge counter triggering button through a charging resistor, a rectifier diode and a damping resistor, and is connected with a digital ammeter through a current limiting resistor and an adjustable resistor; two wires are used as the leading-out wires of the instrument for test according to the invention and are connected with two ends of the lightning arrester monitor. The instrument for lightening arrester monitor test according to the invention has the beneficial effects of simple design, convenient installation, capacity for testing the millammeter and the action counter of the lightning arrester monitor test. The peak current and the effective-value current can be switched freely according to the factory demand of the monitor. Action test can be executed to the action indicator of the monitor. The reliability of the lightning arrester monitor can be guaranteed effectively.
Description
Technical field
The present invention relates to a kind of electric power test apparatus, can finish all tests that require about the present rules of the monitor of lightning arrester.
Background technology
Lightning arrester monitor claims lightning arrester leakance and discharge counter again, be in the high-voltage alternating electric power system with the matching used instrument of Zinc-Oxide Arrester, this instrument is serially connected in the arrester ground loop.Standby current table in the monitor is used to monitor under the working voltage by the leakage current (peak value) of lightning arrester, can judge whether lightning arrester inside makes moist, situation such as whether element is unusual; Operation counter then writes down the superpotential action frequency of lightning arrester.
According to GB50150-2006 " Erection works of electrical installations Standard for handover test of electric equipment " 21.0.5 bar regulation, should carry out two work in the lightning arrester monitor test: the action of 1, checking the discharge register should be reliable; 2, the indication of lightning arrester standby current table should be good.Patrol and examine and stipulate in the explanation according to Q/GDW168-2008 " power transmission and transformation equipment state overhauling testing regulations " 6.18.1.1 bar, if counter is equipped with reometer, should write down current current value, and with equal service condition under the current value of other lightning arrester compare, require no significant difference.
According to two top regulations, the reliability of the necessary safety action of lightning arrester monitor and the accuracy of standby current table index have been determined.And existing test apparatus about lightning arrester monitor only can be finished " performance of checking the discharge register " this function, can not finish lightning arrester standby current table is checked, and that is to say the reliability that can not guarantee lightning arrester monitor.
Summary of the invention
The objective of the invention is to design a kind of instrument that is used for lightning arrester monitor test,, finish the desired pilot project of lightning arrester monitor, guarantee the reliability of lightning arrester monitor to solve above technical barrier.
The implementation procedure of lightning arrester monitor test instrument of the present invention is: with the synthetic circuit in testing current loop and tally function loop, carry out function selecting by current, finish the test of testing current and tally function respectively; Current connects the discharge counter trigger button through charging resistor, commutation diode, damping circuit, connects digital electronic ammeter through current-limiting resistance, adjustable resistance; The check meter extension line is two lines, is connected the lightning arrester monitor two ends.Because the tally function loop voltage reaches about direct current 600V, for electronic device in the protective current test loop, in the protective current test loop, install a protection diode after the digital electronic ammeter additional, this protection diode requires reverse voltage to reach 1000V.
Good effect of the present invention is: simplicity of design, and easy for installation, can carry out verification to the milliammeter and the operation counter of lightning arrester monitor; The requirement of dispatching from the factory according to monitor can freely be changed peak point current and effective value electric current; Can move test to the monitor flag indicator.
