一体化元件化的设计:一体化 微机保护监控系统设计方法可以省去所有的常规仪表、继电器 保护及其各种附件,简化了 二次设计和施工,为用户安装、调试、维护带 来了极大的便利。

自动化、元件化 的微机保护监控系统的设计使得安装方式 灵活,既可集中组屏,又可就 地安装于各种开关柜上;既可连 网构成集成化的保护监控系统,又可单 独安装在开关柜上使之成为智能化开关柜单独运行。

保护功能:针对不 同的一次设备和应用要求,微机保护装 W内可设保护功能库,可实现 三段式过流保护、反时限过流保 护、零序过流二段保护、过负荷、过压、失压、负序二段、备 自投、重合闸、小电流选线、后加速保护、功率方向盥漏电保 护、电缆绝缘监视保护,编程实现非电M跳闸或报瞥等。微机 保护监 控系统的各种保护功能都足相对独立的,拥有自己的设 罝参数和数据记录,从而保 证了装置工作的可靠。


测量功能

微机保 护监控系统的测量功能包括:

电流:la、lb、1c。

零序电流:10。

相电压:Ua、Ub、Uc。

线电j {i:Uab、Uac、Ubc。

零序电抹:U0。

有功功率P,无功率Q,功率因索PF,频率。

上述所 有测揿值可根据用户习惯选择将互感一次测值(或二次测值)显示。


Integrated Component Design: The design method of integrated computer protection monitoring system can save all conventional instruments, relay protection and various accessories, simplify the secondary design and construction, and bring great convenience for users to install, debug and maintain.

The design of automatic and component-based computer protection and monitoring system makes the installation flexible, which can not only centralize the panel, but also be installed on various switchgear in situ. It can not only connect the network to form an integrated protection and monitoring system, but also be installed on the switchgear separately to make it operate as an intelligent switchgear separately.

Protection function: According to different primary equipment and application requirements, the protection function library can be set up in the microprocessor-based protection installation W, which can realize three-stage overcurrent protection, reverse time overcurrent protection, zero sequence overcurrent two-stage protection, overload, overvoltage, voltage loss, negative sequence two-stage protection, standby self-switching, reclosing, low current line selection, post-acceleration protection, power direction toilet leakage protection, cable insulation monitoring and protection. Nursing, programming to achieve non-electric M trip or glance. All kinds of protection functions of the computer protection monitoring system are relatively independent, with its own set-up parameters and data records, thus ensuring the reliability of the device.

Measurement function

The measurement functions of the microprocessor-based protection monitoring system include:

Current: la, lb, 1c.

Zero sequence current: 10.

Phase voltage: Ua, Ub, Uc.

Lines: Uab, Uac, Ubc.

Zero sequence wiping: U0.

Active power P, no power Q, power factor PF, frequency.

All the above measured values can be displayed according to the user's habits.
