Arc Flash Protection Main Unit
SPR63-OP Device
SPR63-OP is a fiber optic temperature rise arc flash protection device, specially designed for remote operation and maintenance of wind turbines. It is suitable for monitoring and alarming arc flash, joint temperature, and current. The device consists of a main unit, photoelectric conversion module, electric temperature sensor, arc flash sensor, optical fiber, and installation accessories. The arc flash sensors are divided into all-optical, white light, and ultraviolet types, with adjustable optical fiber action intensity thresholds. The photoelectric module supports hot swapping.
Technical Parameters
■ Compact size, DIN rail mounting
■ 100~240V ac/dc power input
■ 2 sets of three-phase current monitoring
■ 6 channels of fiber optic arc flash sensor input
■ 32 channels of passive wireless electric temperature collection
■ 5 large-capacity programmable trip output contacts
■ Alarm and trip logic can be set to three modes: "Current", "Arc Flash", "Arc Flash + Current"
■ RS485 and RJ45 communication ports, supporting MODBUS communication protocol
SPR63-WT Device
SPR63-WT is a photoelectric temperature rise arc flash protection device, mainly composed of an arc flash main unit, arc flash sensor, and electric temperature sensor. It monitors arc flash in generators, inverters, transformer boxes, and high and low voltage side switches of wind turbines. The arc flash sensor only supports ultraviolet light and is insensitive to everyday light sources.
Technical Parameters
■ Compact size, DIN rail mounting
■ 100~240V ac/dc power input
■ Three-phase current monitoring
■ 9 channels of arc flash point sensor input
■ 32 channels of passive wireless electric temperature collection
■ 6 large-capacity programmable trip output contacts
■ Alarm and trip logic can be set to three modes: "Current", "Arc Flash", "Arc Flash + Current"
■ Built-in RS485 communication port, supporting MODBUS communication protocol
Arc Flash and Electric Temperature Sensors
Fiber Optic Sensors
■ Sensors are divided into three types: all-optical, white light, and ultraviolet light
■ Ultraviolet sensors do not respond to visible light; this avoids false triggers caused by flashlight illumination during power site inspections;
■ Wide detection range, detection angle exceeds 240 degrees
■ Spectral response bandwidth: 280nm~400nm
■ Standard ST fiber optic interface packaging
■ Operating temperature -40~+85℃
Photoelectric Sensors
■ Light intensity >8000Lux activation
■ 270° detection range
■ Meets IP61 vibration requirements
■ Insensitive to everyday light sources
