Abstract

The protective test control device includes parts: collected signal input, signal calculation circuit, power input, power conversion circuit, status output circuit, status collection circuit, processor, human-computer interaction (HCI) circuit, data storage circuit (DSC), communication circuit, and action executive circuit etc. The protective test control device includes following operations: power conversion circuit converts external power supply too internal voltage; processor analyzes information from status collection circuit; HCI circuit and communication circuit transfer out information; timing parameters of processor is transferred to DSC, and when needed, recorded data are fetched from DSC, and the data are exported to external device through HCI circuit. Characters are that data output mechanism as data output port is setup at HCI circuit; data output port is USB device or serial port data output. The test control device can be installed inside breaker or tripping device.

Description

technical field [0001] The invention relates to a protection measurement and control device with data collection and storage and a data output port, more precisely relates to a protection measurement and control device capable of saving multi-month operation data and with USB and serial port data output, belonging to the technical field of electric power protection measurement and control. technical background [0002] At present, most of the existing electronic intelligent power protection measurement and control devices in China use fieldbus to collect operating data. [0003] Due to the high requirements for fieldbus hardware settings and transmission media, the use of fieldbus to collect operating data for power protection measurement and control points with discrete distribution of network points results in high cost of connecting hardware and low utilization rate of bus settings, resulting in great waste. [0004] The invention stores the parameters of discrete power p...
