描述
主要特性和功能
跳闸和锁定应用：BJ-8RP闭锁继电器的主要用途是提供高度可靠的跳闸和锁定功能。
跳闸：当检测到故障情况（例如，由保护继电器检测到）时，闭锁继电器会快速动作，跳闸（断开）相关断路器，从而隔离电力系统的故障部分。
闭锁：跳闸后，继电器进入“锁定”状态，防止断路器或其他关键电力设备（例如电力变压器或发电机）在手动或电气复位之前重新通电。这可以防止设备在持续故障情况下（例如，气压、油位、温度问题）重新通电。
高质量要求：专为需要极快动作时间和高分断能力的严苛应用而设计。
手动复位：型号名称中的“RP”表示“复位按钮”，这意味着跳闸后需要手动复位，确保操作员在重新启用系统之前了解事件情况。
触点配置：它具有8个转换触点（8PDT或Form-C）。这意味着它有8组触点，每组都有一个公共端子、一个常开(NO)端子和一个常闭(NC)端子。这为同时控制多个设备或发送多个信号提供了灵活性。
快速操作时间：Arteche锁定继电器以其快速操作而闻名，通常在3到20毫秒(ms)之间。这种速度最大限度地减少了对总跳闸时间的影响，这对于保护昂贵的电力设备至关重要。
高分断能力：触点设计用于直接分断大电流，使其能够直接连接到断路器跳闸线圈，而无需介入继电器。
高介电强度（电气隔离）：确保输入和输出电路之间高水平的电气绝缘，保护控制系统免受来自一次设备电路的潜在损坏。
坚固耐用的设计：专为在严苛环境下可靠运行而设计：
即使在高温下也能长期运行。
可在100%相对湿度的环境中工作。
具有抗震特性，可在地震多发地区使用。
耐振动。
自清洁触点确保长期可靠性。
合规性：符合各种通用标准，包括IEC 61000、IEC 60947、IEC 60255和ANSI C37.90，确保互操作性和安全性。
Key Features and Functions
Tripping and Locking Applications:The primary purpose of the BJ-8RP lockout relay is to provide highly reliable tripping and locking functions.
Tripping:When a fault condition is detected(e.g.,by a protection relay),the lockout relay quickly operates to trip(open)associated circuit breakers,isolating the faulty section of the power system.
Lockout:After a trip,the relay enters a”locked out”state,preventing the circuit breaker or other critical power equipment(like power transformers or generators)from being re-energized until a manual or electrical reset is performed.This protects the equipment from being re-energized under persistent fault conditions(e.g.,gas pressure,oil level,temperature issues).
High Quality Requirements:Designed for demanding applications where very fast operating times and high breaking capacity are essential.
Manual Reset:The”RP”in the model name indicates”Reset Push-button,”meaning it requires a manual reset after a trip,ensuring an operator is aware of the event before re-enabling the system.
Contact Configuration:It features 8 Changeover(8PDT or Form-C)contacts.This means it has 8 sets of contacts,each with a common terminal,a normally open(NO)terminal,and a normally closed(NC)terminal.This provides flexibility for controlling multiple devices or sending multiple signals simultaneously.
Fast Operating Time:Arteche lockout relays are known for their fast operation,typically between 3 and 20 milliseconds(ms).This speed minimizes the impact on the total trip time,which is critical for protecting expensive power equipment.
High Breaking Capacity:The contacts are designed to directly break significant currents,allowing them to be connected directly to circuit breaker trip coils without the need for interposing relays.
High Dielectric Strength(Galvanic Isolation):Ensures a high level of electrical insulation between input and output circuits,protecting the control system from potential damage originating from the primary equipment circuit.
Robust Design:Built to perform reliably in demanding environments:
Designed for permanent service,even at high temperatures.
Can operate in environments with 100%relative humidity.
Possesses seismic characteristics,allowing its use in earthquake-prone areas.
Resistant to vibrations.
Self-cleaning contacts ensure long-term reliability.
Compliance:Meets various general standards,including IEC 61000,IEC 60947,IEC 60255,and ANSI C37.90,ensuring interoperability and safety.
