Embodiment Construction

[0032] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0033] Such as figure 1 , image 3 As shown, the intelligent test system for re-inspection of the relay protection device of the present invention includes an industrial robot, a feeding subsystem, a robot control center (RCC), and several intelligent test units (STU). The feeding subsystem consists of feeding trolleys, tracks, and auxiliary electrical equipment. The intelligent test unit consists of a relay protection device test device, an AC / DC voltage current program control output device, an intelligent test control center (STCC), a gas valve management control device, auxiliary electrical equipment and a cabinet.

[0034] The robot moves from the trolley moving device to the designated station of the intelligent test unit. The method for the robot to identify the position of the device is determined by the signal generated by the grati...

Abstract

The invention discloses a relay protection device complete machine reinspection intelligent test system and method. The system comprises a robot, a feeding subsystem, a robot control center and a plurality of intelligent test units. The feeding subsystem comprises a feeding trolley, a track and auxiliary electrical equipment. The intelligent test unit comprises a relay protection device complete machine test device, an AC / DC voltage and current program control output device, an intelligent test control center, an air valve management control device, auxiliary electrical equipment and a cabinet. The robot positions the device according to different types of trolleys, moves the device to a test station, scans a bar code of the device to obtain a specific signal, establishes a closed-loop test environment, and then starts the whole machine for testing. And after the whole machine test is correct, analog quantity channel precision verification is started. After the test succeeds, the robot moves the device back to the trolleys; and if the test fails, the robot moves the device to an NG area. Unmanned operation and standardized detection are realized in the whole process, and the whole machine reinspection detection efficiency of the relay protection device is effectively improved.

Description

technical field [0001] The invention relates to an intelligent test system, in particular to an intelligent test system and method for rechecking a complete relay protection device. Background technique [0002] In recent years, with the rapid development of power grid construction, the demand for power secondary protection equipment has grown rapidly, especially low-voltage protection equipment. This also highlights the drawbacks of the original manual retest or semi-automatic retest methods. The testing efficiency is low, the cost of human testing is high, and the level of intelligent testing of enterprises is low. Therefore, it is necessary to change the current testing methods to meet the challenges of the times and the cost pressure of enterprises. [0003] The manual testing process of relay protection devices is cumbersome and inefficient. And it itself requires high, precise and accurate testing. On the one hand, there are many hard contacts in the relay protectio...
