relay function

While our new product, the intelligent electrical apparatus with communication ability, can not only realize the time limit rapid action relay function independently but display and modify the action parameter of relay such as the current and the time.

而我们设计的可通信智能限时速切电流继电器，不仅能够独立完成单点的限时速切保护功能，并能够在现场对继电器动作参数（如电流、时间）进行显示和修改。

Using the relay function of a prepositive controller, the PC can communicates with intelligent nodes through principal and subordinate semiduplex wireless network, which constitute the distributed measurement and controlling system.

通过前置机的中继功能，PC机与各个智能节点组成一个主从式半双工无线通信网络，构成集散式测控系统。

Having been run on simulated experiments for many times, the designed device measures up to requirements of the relay function, which is of certain engineering value.

通过实验，设计的装置多项性能指标符合继电保护的要求，有一定的工程意义。

Compared to conventional software design based on flow chart, the protection software is developed based on relay function module, which leads to the separation of time sequence and logic.

该方法摒弃了传统的基于流程图的设计思路，将软件的时序与逻辑分离，模块性好，结构清晰，软件的开发、维护方便。

Based on a practical software package for automatic test, it also puts forward a object-oriented design idea which merges relay management function and relay testing function together, incarnates the automatic, visual, intelligent trend of test systems.

以一个基于保护测试仪的自动测试软件包为例，提出继电器管理和保护测试一体化的面向对象设计思路，体现了保护测试系统的自动化、可视化、智能化的发展趋势。
