UR8AH   继电器 具有保护和开关功能的通用设备

产品描述

通用电气Multilin公司的UR- 8ah是通用继电器系列的CT/VT模块，为UR继电器提供1A/5A相CT, 1A/5A接地CT和4个电压互感器。电压互感器和电流互感器将电力系统的电压和电流值按比例降低到通用继电器可以识别和调节的值。

UR8AH该模块还提高了操作人员的整体安全性，因为变压器的部分二次绕组必须连接到地面。此外，它们允许在系统内产生不安全条件的故障识别和纠正。最后，提供的数据使用户能够确保为整个机器和电网提供充分的保护。

通用继电器是一种具有保护和开关功能的通用设备。它主要分为电磁继电器和固态继电器两种类型。

UR8AH电磁继电器只有一个线圈，当线圈通电后会产生磁场，这个磁场会吸引继电器的衔铁并推动其运动，同时带动继电器的触点运动。常开电磁场继电器可带来以下效果：常开触点闭合，常关断触点。当线圈无电流通过时，继电器的接线也会自动恢复到原来的状态，即常开常闭触点都会复位。

固态继电器属于非接触式开关，内部是电子电路。它的输入和输出部分都很明确，输出端是一个开关，可以通过调整输入端来实现输出端的开关量。

The UR8AH relay is a universal device with protection and switching functions

Product description

The UR-8AH from GE Multilin is a CT/VT module in the General purpose relay family that provides a 1A/5A phase CT, a 1A/5A ground CT and 4 voltage transformers for UR relays. Voltage transformers and current transformers reduce the voltage and current values of a power system proportionally to a value that a general purpose relay can recognize and regulate.

The UR8AH module also improves the overall safety of the operator, as part of the transformer's secondary windings must be connected to the ground. In addition, they allow for fault identification and correction of unsafe conditions within the system. Finally, the data provided enables users to ensure adequate protection for the entire machine and the grid.

A universal relay is a universal device with protection and switching functions. It is mainly divided into electromagnetic relay and solid-state relay two types.

The UR8AH electromagnetic relay has only one coil, and when the coil is energized, a magnetic field will be generated, which will attract the armature of the relay and promote its movement, and drive the contact movement of the relay. Normally open electromagnetic field relays can bring the following effects: normally open contact closed, normally closed contact. When no current passes through the coil, the relay wiring will automatically return to the original state, that is, the normally open and normally closed contacts will be reset.

A solid state relay is a non-contact switch with an electronic circuit inside. Its input and output parts are very clear, the output is a switch, you can adjust the input to achieve the output of the switch.
