REF615E ABB 继电保护装置

REF615E ABB 继电保护装置通过允许更大的电流流动来打开设备继电器是一种电动或机电开关，由电磁铁、衔铁、弹簧和一-组电触点组成。电磁开关由小电流操作，通过释放或缩回衔铁触点来接通或切断大电流，从而切断或接通电路。当受控电路和控制电路之间必须有电气隔离时，或者当多个电路需要由单个信号控制时，继电器是必要的。继电器是一个电磁开关;因此，它的心脏是电磁体，由小电流供电，充当杠杆或开关本身。这使得允许相对小的电流影响和控制大得多的电流成为可能。传感器是敏感的设备,它们只产生少量的电流，但为了让传感器驱动更大的设备，它需要某种东西通过允许更大的电流流动来打开设备。样，传感器可以作为继电器的控制输入，当它被激活时，更大的电流流向设备。例如，可以分配光或光传感器来控制室外的灯，以便当外面变暗时，光传感器激活充当灯开关的继电器。

REF615E ABB relays turn equipment on by allowing greater current flow A relay is an electric or electromechanical switch consisting of an electromagnet, armature, spring, and a set of electrical contacts. The electromagnetic switch is operated by a small current, and a large current is switched on or off by releasing or retracting the armature contact, thus cutting or closing the circuit. Relays are necessary when there must be electrical isolation between the controlled circuit and the control circuit, or when multiple circuits need to be controlled by a single signal. The relay is an electromagnetic switch; Thus, its heart is the electromagnet, powered by a small current that acts as a lever or the switch itself. This makes it possible to allow relatively small currents to influence and control much larger currents. Sensors are sensitive devices, and they only produce a small amount of current, but in order for a sensor to drive a larger device, it needs something to turn the device on by allowing a larger flow of current. Like, the sensor can act as a control input to the relay, and when it is activated, a greater current flows to the device. For example, light or light sensors can be assigned to control lights outside so that when it gets dark outside, the light sensor activates a relay that acts as a light switch.

Function: Feeder protection devices are used to monitor and protect feeders (cables or wires) in a power system. It can detect current anomalies, voltage anomalies, and other fault conditions and take action when needed to prevent damage or danger to the power system.

Protection function: The device may have a variety of protection functions, such as overcurrent protection, short circuit protection, ground fault protection, trip function, etc. Different protection functions can protect the power system from different types of failures.

Communication interface: The REF615E-D may have a communication interface for data exchange with other equipment or monitoring systems. This communication can be used for remote monitoring, control, and diagnostics.

Configuration and programming: This type of protection usually needs to be configured and programmed to suit specific power system requirements. You can set different parameters and protection policies as required.

Application: Feeder protection devices are widely used in power systems, industrial fields, and other occasions that need to ensure the stable and reliable operation of power systems.
