Switching value testing device and method

Abstract

The invention discloses a switching value testing device and method, wherein the device comprises an acquisition output device and a display issuing device which are connected through a network cable; the acquisition output device comprises a switching-in output terminal and a switching-out acquisition terminal which are in direct insertion connection with switching-in and switching-out terminals of a to-be-tested device; a switching-out signal of the to-be-tested device is acquired, and the switching-out signal is transmitted to a display issuing device through a network cable; meanwhile, a switching-in signal is output; the display issuing device comprises a switching-in state control button and switching-in / switching-out state display lamps, the switching-in state control button controls the switching-in signal, and the switching-in signal is transmitted to the acquisition output device through a network cable and is displayed through the switching-in state display lamp; and the switching-out state display lamp displays the switching-out signal. According to the invention, signal output and acquisition are integrated into one module, and the module is directly inserted into a to-be-tested device, so that signal lines are reduced; and a multi-path switch signal is converted into a digital signal, the digital signal is sent to a receiving end through an Ethernet cable, the receiving end can display the multi-path output state and control the switching-in state, and the development and test efficiency is improved.

Description

technical field [0001] The invention belongs to the field of power grid automation control, in particular to a switching value testing device and method. Background technique [0002] In recent years, with the continuous improvement of the power grid's requirements for relay protection devices and safety automatic devices, the domestic standardization requirements for relay protection devices and safety automatic devices have become higher and higher. Nine unified network access tests, standardized design of safety automatic devices, and testing of various types of devices are required according to the standardized design plan. [0003] Relay protection devices and safety automatic devices in power systems often collect switching signals (switching in) and output switching signals (switching out). In the device debugging stage, there are a large number of input signals and output signal wiring for the unwired device test. Relay protection devices and safety automatic devic...
