应用领域

RMV-112D保护电压继电器用于发电机、发动机和变压器保护，防止异常系统电压的情况。

RMV-112D继电器是一种电控制器件，是当输入量（激励量）的变化达到规定要求时，在电气输出电路中使被控量发生预定的阶跃变化的一种电器。它具有控制系统（又称输入回路）和被控制系统（又称输出回路）之间的互动关系。通常应用于自动化的控制电路中，它实际上是用小电流去控制大电流运作的一种“自动开关”，故在电路中起着自动调节、安全保护、转换电路等作用。

继电器的工作原理是利用电磁效应来控制机械触点达到通断目的，给带有铁芯线圈通电--线圈电流产生磁场--磁场吸附衔铁动作通断触点，整个过程是"小电流-磁-机械-大电流"这样一个过程。

RMV-112D继电器是一种靠电磁感应工作的自动化电器开关，输入回路和输出回路之间一般需要用隔离器件来实现隔离。电磁继电器里边，需要有线圈，铁芯，弹簧，触点等关键配件来组成。

Description

Product description

The RM-112D DEIF's RMV protection voltage relay is designed to protect generators, motors and transformers against adverse system voltage conditions. The multifunctional device has many adjustable parameters.

trait

With high precision

High reliability

Multifunctional feature

The protective voltage relay is RV-12D. The product also has a three-phase measurement function and a timer control trip function. Therefore, the LED indication of the howl status and the LED indication of the activated relay. It measures 35 mm DIN rail or base mount.

The RV-112D DEF voltage maintaining relay has two outputs: U< output corresponding to undervoltage contact and U&.gt output corresponding to overvoltage contact, on or off. When activated, the contact can be set to normally open or normally closed. Often enabled coils are recommended for land installations for warning and warning. The contact is activated immediately when the auxiliary power is cut off. Normal power off contacts are recommended for Marine applications for regulation and control. Secondary power failure does not cause contact activation. The self-locking circuit allows the contact to be locked in the warning position even if the input voltage returns to normal (add to the contact type of the order specification as needed). The self-locking circuit can be reset by disconnecting the auxiliary power supply. Power-on/power-off electric relay is equipped with 200ms power-on relay circuit to ensure the normal function of the relay when connecting the auxiliary voltage.

Application field

The RV-112D protective voltage relay is used to protect generators, engines and transformers against abnormal system voltage situations.

The RV-112D relay is an electrical control device, which is an electrical appliance that makes the controlled quantity undergo a predetermined step change in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automated control circuits, it is actually an "automatic switch" that uses small current to control the operation of large current, so it plays an automatic regulation, safety protection, conversion circuit and other roles in the circuit.

The working principle of the relay is to use the electromagnetic effect to control the mechanical contact to achieve the purpose of on-off, to energize the coil with an iron core - the coil current generates a magnetic field - the magnetic field absorbs the armature action to break the contact, the whole process is "small current - magnetic - mechanical - large current" such a process.

The RV-112D relay is an automatic electrical switch that works by electromagnetic induction. Isolation devices are generally needed to realize isolation between the input loop and the output loop. Inside the electromagnetic relay, it is necessary to have key accessories such as coils, iron cores, springs, and contacts.
