Description
Technical field
The utility model 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 purpose of this utility model is a kind of instrument that is used for lightning arrester monitor test of design, to solve above technical barrier, finishes the desired pilot project of lightning arrester monitor, guarantees the reliability of lightning arrester monitor.
The implementation procedure of lightning arrester monitor test instrument described in the utility model is: with the synthetic circuit in testing current loop and tally function loop, current connects testing current loop and tally function loop respectively, finishes 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 test instrument 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 utility model 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.

Concrete using method
1, wiring output lead red end is connected on the conducting rod a of monitor upper end, and black terminates on the monitor earthing of casing b;
2, check current adjusting knob 12 zero setting positions, pressure regulator adjusting knob 19 zero setting positions connect the 220V experiment power supply;
3, electric current verification: current 6 is got on the current gear, reometer peak value/effective value switch 18 is got to the tram, regulate pressure regulator adjusting knob 19, observe the reometer index, if electric current can not satisfy the verification requirement, regulate current adjusting knob 12;
4, action frequency verification: current 6 is got on the counting shelves, pressure regulator adjusting knob 19 is transferred to the action index location, regulates and press discharge index count button 10 after suitable, whenever press a lightning arrester monitor and move once.
