一、概述overview
wsl-10-3t微机过流保护装置适用于电力城、农网供电线路、变压器、电动机的过负荷和短路保护，具备rs485通讯接口可实现数据远传。
wsl-10-3t microcomputer suitable for protection of overload and short circuit of power supply circuit of urban and rural, transformer and electric motor, and able to achieve data telecommunication through rs485 communication contact.
该保护装置为高压柜三相电流保护，液晶显示。保护功能有过电流保护、堵转速断保护、短路速断保护、过流延时动作（定时限、反时限）、速断延时动作（定时限）、过流启动闭锁延时（当启动延时设为0秒时，保护装置为常规的过流速断保护）。各种动作信号保持和复归功能。
the protector is three-phase overcurrent protection for high-voltage switch cabinet with lcd display. it has overcurrent protection, lock-rotation quick-break protection, short-circuit quick-break protection, overcurrent deferred action (definite time limit, inverse time limit), quick-break deferred action(definite time limit), overcurrent start block delay(when start delay 0 sec, protector will be general overcurrent quick-break protection). all kind of actuating signal has retain and reset function.
该保护采用定时限和反时限设计，即作用于继电器的电流大，动作时间短，反之动作时间长。因此该系列产品特别适合10kv高压长线路、变压器及电动机的过负荷保护。
the protector use definite time limit and inverse time limit design, that means the greater the current act on relay, the shorter the action time will be, otherwise action time will be longer. so this series product especially suitable for overload protection of 10kv high-voltage long line, transformer and electric motor.
动作方式:action mode
可选择一路主触点过流和速断都动作，另一路作为信号触点报警（11/12功能）。
able to select one route main contact's overcurrent and quick-break both act, another route as signal contact alarm.(11/12 function)
可选择一路主触点速断动作，另一路辅助触点过流延时动作（13/14功能）。
able to select one route main contact's quick-break act, another route
