Problems solved by technology

[0004] The above-mentioned long-distance cable obtains the power supply for the outdoor tester, and the power supply line is easily damaged, resulting in test interruption and data loss; if the test point is in a remote area, it is impossible to find a suitable power supply for the outdoor tester, and the voltage is too low or unstable , will cause abnormal operation of the outdoor tester, loss of test data and other faults; in addition, long-distance cable power supply and test circuit wiring are many and complicated, which makes the whole test process difficult

Embodiment Construction

[0022] A power supply method for an outdoor tester, involving a power supply device and an outdoor tester, comprising the following steps:

[0023] S1: Determine the power supply type and voltage level required by the outdoor tester 8;

[0024] S2: Connect the power supply device to the outdoor tester 8;

[0025] S3: Connect the input terminal 1 of the power supply device to the AC power supply, start the power supply device and the outdoor tester 8 respectively, and complete the power supply.

[0026] like figure 1 As shown, the present invention relates to a power supply device and an outdoor tester 8. The power supply device includes: an input terminal 1, a switch 2, an insulated gate bipolar transistor 4, and a power supply terminal 7. The output end of the input terminal 1 is connected to a switch The input end of the switch 2, the output end of the switch 2 is connected to the input end of the IGBT 4, the output end of the IGBT 4 is connected to the input end of the po...

Abstract

The invention provides an outdoor tester power supply method and relates to a power supply device and an outdoor tester. The outdoor tester power supply method comprises the following steps: 1, determining the power source type and the voltage grade required by the tester; 2, connecting the power supply device with the outdoor tester; 3, connecting the power supply device to an alternating current power supply, starting the power supply device and the outdoor tester and finishing power supply respectively. The power supply method can achieve the purpose of getting electricity from the neighborhood, avoids complex work of bracing wires in long distance and is simple to operate, portable and practical; when an external power supply cannot meet the power consumption requirement of the outdoor tester, an internal storage battery coming with the power supply is started to supply power for the outdoor tester; thus, the reliability is strong, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of power instrument testing and power supply, in particular to a power supply method for an outdoor test instrument. Background technique [0002] In recent years, with the rapid development of my country's social economy and the continuous improvement of people's living standards, the demand for electricity has gradually increased, resulting in many low-voltage problems in power supply lines. Accurate diagnosis and resolution of low-voltage problems are difficult problems faced by major power supply companies. According to relevant regulations, outdoor testers are mostly used to test low-voltage areas, and further diagnosis and solutions are made based on test data. For example, the power quality analyzer is a special portable product for detecting and analyzing the operation quality of the power grid. It can provide harmonic analysis and power quality analysis in power operation, and can carry out long-ter...
