REF615E ABB 繼電保護(hù)裝置通過(guò)允許更大的電流流動(dòng)來(lái)打開(kāi)設(shè)備繼電器是一種電動(dòng)或機(jī)電開(kāi)關(guān),由電磁鐵、銜鐵、彈簧和一-組電觸點(diǎn)組成。電磁開(kāi)關(guān)由小電流操作,通過(guò)釋放或縮回銜鐵觸點(diǎn)來(lái)接通或切斷大電流,從而切斷或接通電路。當(dāng)受控電路和控制電路之間必須有電氣隔離時(shí),或者當(dāng)多個(gè)電路需要由單個(gè)信號(hào)控制時(shí),繼電器是必要的。繼電器是一個(gè)電磁開(kāi)關(guān);因此,它的心臟是電磁體,由小電流供電,充當(dāng)杠桿或開(kāi)關(guān)本身。這使得允許相對(duì)小的電流影響和控制大得多的電流成為可能。傳感器是敏感的設(shè)備,它們只產(chǎn)生少量的電流,但為了讓傳感器驅(qū)動(dòng)更大的設(shè)備,它需要某種東西通過(guò)允許更大的電流流動(dòng)來(lái)打開(kāi)設(shè)備。樣,傳感器可以作為繼電器的控制輸入,當(dāng)它被激活時(shí),更大的電流流向設(shè)備。例如,可以分配光或光傳感器來(lái)控制室外的燈,以便當(dāng)外面變暗時(shí),光傳感器激活充當(dāng)燈開(kāi)關(guān)的繼電器。

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.
