产品详细资料
引言本节中包含的程序可用于在745变压器保护系统投入使用之前验证其是否正确运行。这些程序也可用于定期验证继电器。虽然不是全面的功能验证，但本章中的测试验证了继电器所有功能的主要操作点。在调试继电器之前，用户应阅读安装章节，该章节提供了有关接线、安装和安全问题的重要信息。用户还应熟悉设定值和实际值章节中所述的继电器。测试人员必须熟悉一般继电器测试实践和安全预防措施，以避免人身伤害或设备损坏。本章分为几个部分，如下所示：•概述：概述了测试程序中使用的安全预防措施和惯例。•测试设备：所需的测试设备。•一般初步工作•逻辑输入和输出继电器：测试所有数字和模拟输入、模数数据采集系统以及继电器和晶体管输出。•显示、计量、通信、模拟输出：测试从交流电流和电压输入得出的所有值。•保护方案：测试可能导致跳闸的所有功能，包括差动、过电流、过频和低频元件。•辅助保护/监测功能•将继电器投入使用•设定值表
Introduction The procedures contained in this section can be used to verify the correct operation of the 745 Transformer Protection System prior to placing it into service for the first time. These procedures may also be used to verify the relay on a periodic basis. Although not a total functional verification, the tests in this chapter verify the major operating points of all features of the relays. Before commissioning the relay, users should read the installation chapter, which provides important information about wiring, mounting, and safety concerns. The user should also become familiar with the relay as described in the setpoints and actual values chapters. Test personnel must be familiar with general relay testing practices and safety precautions to avoid personal injuries or equipment damage. This chapter is divided into several sections, as follows: • GENERAL: outlines safety precautions, conventions used in the test procedures. • TEST EQUIPMENT: the test equipment required. • GENERAL PRELIMINARY WORK • LOGIC INPUTS AND OUTPUT RELAYS: tests all digital and analog inputs, the analog-to-digital data acquisition system, and relay and transistor outputs. • DISPLAY, METERING, COMMUNICATIONS, ANALOG OUTPUTS: tests all values derived from the AC current and voltage inputs. • PROTECTION SCHEMES: tests all features that can cause a trip, including differential, overcurrent, over and underfrequency elements. • AUXILIARY PROTECTION/MONITORING FUNCTIONS • PLACING RELAY INTO SERVICE • SETPOINT TABLES
