自动消弧线圈及接地选线一体化装置的低压模拟试验

为检验自动消弧线圈及接地选线一体化装置的测控系统的各项性能指标,在实验室搭建了低压模拟试验电路,其控制系统可以单片机或者PLC两种方式来实现。文中给出了两种控制方式详细的硬件和软件框图。在所搭建的低压模拟试验环境里对测控系统进行的各项功能性试验表明,所研制的低压模拟试验电路可进行电容电流测量试验、单相接地试验、接地选线试验等多项试验,有一定的推广应用价值。

Low-voltage Simulation Test of the Integrated Device of Automatic Arc-suppression Coil and Grounding Fault Line Determination

In order to test all performance indexes of the measurement and control system of the integrated device of automatic arc-suppression coil and grounding fault line determination,a circuit for low-voltage simulation test is built in laboratory.The control system of the circuit can be implemented by a single-chip microcomputer or PLC.The hardware and software diagrams of the two control systems are given.Functional tests on the measurement and control system are conducted in the low-voltage simulation system,and the results show that the simulation system can perform such tests as capacitive current measurement,single-phase grounding,grounding fault line determination,etc.with low cost and simple operation.
