Embodiment Construction
[0027] A self-switching power supply method for an outdoor tester, involving a power supply device and an outdoor tester 10, the power supply device providing power for the outdoor tester 10, comprising the following steps:
[0028] S1: Determine the power supply type and voltage level required by the outdoor tester 10, the power supply type and voltage level are 24V or 48V DC and 220V or 380V AC;
[0029] S2: Connect the power supply device and the outdoor tester 10, connect the power supply device to an AC power source, start the power supply device and the outdoor tester 10 respectively, and start supplying power;
[0030] S3: The power supply device detects the input voltage in real time, if normal, continue to supply power, if not normal, switch to other circuits to continue power supply;
[0031] Complete self-switching power supply.
[0032] Such as figure 1 As shown, the power supply device includes four input terminals, namely A`, B`, C` and N`, four power supply te...

The invention discloses an automatic switching power supply method of an outdoor tester, and relates to a power supply device and an outdoor tester. The method comprises the following steps of (1) detecting a power supply type and a voltage grade which are required by the outdoor tester; (2) connecting the power supply device with the outdoor tester, accessing an AC power supply to the power supply device, respectively starting the power supply device and the outdoor tester, and starting to supply power; and (3) detecting an input voltage by the power supply device in real time, continuing to supply power if the input voltage is normal, switching to the other loops and continuing to supply power if the input voltage is not normal, so that automatic switching power supply is completed. By using the method, power taking as near as possible is achieved, the other loops can be automatically switched when the voltage of a certain loop is not normal, and a battery unit is switched and a battery supplies power when the voltages of all loops do not conform to the requirement. The device is simple to operate, is portable and practicable, and is high in reliability and wide in application range.
Description
technical field [0001] The invention relates to the technical field of power instrument testing and power supply, in particular to a self-switching power supply method for an outdoor tester. 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 lo...
