Problems solved by technology

The ammeter of the lightning counter reflects the value of the total current of the arrester during the operation of the arrester, which can reflect the insulation condition of the arrester. Therefore, it is required to calibrate the ammeter of the lightning counter before the operation of the arrester. Now there are only instruments for testing single-phase lightning counters. The phase arrester needs three measurements, which is a waste of test time and is not conducive to the comparison of the three test data. It takes a long time and is not conducive to the timely power transmission of the equipment

Embodiment Construction

[0009] Below by specific embodiment, further illustrate advantage of the present invention:

[0010] A method for testing a lightning counter. Firstly, one end of the counter high-voltage terminal of the lightning counter is introduced into the high-voltage lead socket of the test instrument, and the counter ground terminal at the other end is grounded; High-voltage lead socket, compare the ammeter indications of the three lightning counters; then, if the test line is short-circuited, the high and low voltages are reversed, the fuse will be blown. After the fuse is blown, if the measurement is performed, it will display "Measuring, please wait" and then stop .

[0011] The present invention changes the previous three-phase arrester to one measurement, which saves time and manpower, and the accuracy of the measurement result is high, so that the ammeter calibration of the arrester becomes very convenient, and it can be quickly measured and sent in time. Ensure the reliability ...

Abstract

The invention discloses a testing method for lightning counters, which comprises the following steps: firstly, counter high voltage terminals at one ends of the lightning counters are introduced into a high voltage lead socket of a tester and counter earthing terminals at the other ends of the lightning counters are earthed; three lightning counters are connected into the high voltage lead socket of the tester according to A, B and C phases and ammeter indications of the three lightning counters are compared; and then, in the case of short circuit of a testing line, a high voltage and a low voltage are reversed, a fuse can be fused, and after the fuse is fused, if the measurement is carried out, the words of 'measuring, please wait' are displayed and then the lightning counters are shut down. According to the invention, a conventional method of measuring a three-phase lightning arrester for three times is changed into the method for measuring the lightning arrester for once, so that both time and labor are saved and the measurement result has high accuracy, and thus, an ammeter of the lightning arrester is very convenient to check and can be rapidly measured, power is timely fed, and the power supply reliability is ensured.

Description

technical field [0001] The invention belongs to the technical field of lightning arresters, and in particular relates to a lightning counter test method. Background technique [0002] With the continuous development of the economy, the requirements for power supply reliability are getting higher and higher. The ammeter of the lightning counter reflects the value of the total current of the arrester during the operation of the arrester, which can reflect the insulation condition of the arrester. Therefore, it is required to calibrate the ammeter of the lightning counter before the operation of the arrester. Now there are only instruments for testing single-phase lightning counters. The phase arrester requires three measurements, which is a waste of test time and is not conducive to the comparison of the three test data. It takes a long time and is not conducive to the timely power transmission of the equipment. Contents of the invention [0003] The object of the present i...
