Abstract

The invention discloses a portable experimental power source device, comprising a box body, a handle arranged on the box body, and rollers arranged at the bottom of the box body. A power module, an inverting module, a transforming module, a control switch and a socket are arranged in the box body. The control switch is an earth leakage protective switch or an overcurrent protective switch; the socket includes a first socket and a second socket, the power module, the control switch, the inverting module and the first socket are connected in succession, the first socket, the transforming module and the second socket are connected in succession, and the power module is rechargeable. In the invention, automatic power-off is achieved by adding the control switch to a circuit.

Description

technical field [0001] The invention relates to a circuit maintenance device, in particular to a portable test power supply device. Background technique [0002] When the power supply secondary equipment such as electric energy metering instruments and meters, operation and dispatching power mining terminals are commissioned and repaired on site, it is often necessary to connect the test power supply. Commonly used debugging and calibration methods are as follows: Method 1, remove the equipment that needs to be corrected from the station area (substation) and send it back to the laboratory for calibration, which consumes a lot of manpower and material resources, and the efficiency is extremely low, which not only affects the normal The safe power supply also caused unnecessary customer complaints; the second method is to use an AC diesel generator to generate AC power at the school repair site, and then transform it through a voltage regulator and rectify it with a rectifier...
