Abstract

The invention discloses a portable transformation operation and maintenance terminal. The portable transformation operation and maintenance terminal comprises a test chip, a switching circuit, a firstprotection/conversion circuit, a second protection/conversion circuit, an IIC-to-IO module, a first isolation chip, a second isolation chip and a CPU module, wherein the first protection/conversion circuit is connected to the test chip by the switching circuit, the second protection/conversion circuit is connected to the test chip, the test chip is connected with the IIC-to-IO module and the second isolation chip, the IIC-to-IO module is connected to the CPU module by the first isolation chip, the second isolation chip is connected to the CPU module, the switching circuit is further connectedbetween the IIC-to-IO module and the test chip, the first protection/conversion circuit is used for measuring a voltage, a resistor, a diode and a capacitor, and the second protection/conversion circuit is used for measuring a current. With the test chip to test, traditional control by a knob is abandoned, more intelligence is achieved, no mechanical operation error is generated, display is controlled by the CPU module, and a display interface can be more flexible, versatile, rich and humanized.

Description

technical field [0001] The invention relates to a portable power transformation operation and maintenance terminal, which belongs to the technical field of portable operation and maintenance equipment. Background technique [0002] At present, there are many types of measurement and maintenance equipment carried on-site for operation, maintenance and maintenance of smart substations, such as multimeters, infrared imagers, network communication testers, optical fiber probes, etc., and mobile operating platforms need to be carried to record relevant test data. Work often has shortcomings such as poor or delayed work quality due to incomplete or missing tools, incomplete test data records due to tediousness, low data quality, and difficulty in long-term health analysis of equipment status. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a portable power transformation operation and maintenance terminal to solve the ...
