Tester wiring concentration conversion device for vehicle

Abstract

The invention relates to a tester wiring concentration conversion device for a vehicle. The tester wiring concentration conversion device for the vehicle comprises an adapter board which is provided with a relay control panel, a central processing unit (CPU) control panel used for controlling the relay control panel, an analog quantity switch communication channel selecting module, an upper computer and a communication interface, wherein the upper computer and the communication interface are used for giving a command control to the CPU control panel. An electrical power vehicle-mounted three phase direct-current resistance tester, a transformer no-load voltage ratio tester and a testing wire of a transformer on-load tap-changer tester are respectively mounted on the adapter board. The communication interface is connected with the analog quantity switch communication channel selecting module which is respectively connected with the upper computer and the CPU control panel. The CPU control panel is further connected with the relay control panel. The analog quantity switch communication channel selecting module selects communication channels through the control of the upper computer. The relay control panel carries out the control command of the CPU and enables the needed relay operation to be achieved, thus reaching the mode of connection and realizing the switchover among the three phase direct-current resistance tester, the transformer no-load voltage ratio tester and the transformer on-load tap-changer tester.

Description

technical field [0001] The invention relates to a centralized conversion device, in particular to a vehicle-mounted three-phase DC resistance, transformation ratio, and on-load comprehensive tester wiring centralized conversion device. Background technique [0002] At present, conventional high-voltage test electric comprehensive test vehicles are generally equipped with transformer DC resistance tester, transformer ratio tester, and transformer on-load tap-changer tester. These three instruments have four sets of test lines Aa, Bb, and Cc respectively. , Oo, the conventional method in the past was to connect the four sets of wires of the instruments to the test object from the four instruments respectively. The three instruments have different lines and different connection methods. The electric power converted in this way There are many wiring on the car, wiring once for a single test item, many times of climbing, high probability of potential safety hazards, many types of...

[0002] At present, conventional high-voltage test power comprehensive test vehicles are generally equipped with transformer DC resistance tester, transformer ratio tester, and transformer on-load tap-changer tester. These three instruments have four sets of test lines Aa, Bb, and Cc respectively. , Oo, the conventional method in the past was to connect the four sets of wires of the instruments to the tested product from the four instruments respectively. The three instruments have different lines and different connection methods. The electric power converted in this way There are many wiring on the car, wiring once for a single test item, many times of climbing, high probability of potential safety hazards, many types of test lines, and long time spent on rewinding and unwinding. The long waiting time at the test site prolongs the power outage time of the substation, resulting in a waste of manpower and material resources
