美国GE通用MIFIIPI55E10HI00馈线保护装置接口PLC系统继电器供应Relay is a kind of industrial equipment widely used in the electrical system. Its normal action plays a certain role in protecting various faults, but when this protection fails, it will cause the system paralysis. If the switchgear fails or the circuit is automatically disconnected for protection. Therefore, pay attention to the action of relay frequently during operation. Now we mainly introduce GE relay protection device. When a fault occurs on the equipment, the relay protection device can be used for protection to prevent maloperation or tripping due to automatic tripping of the protection line.General functions: 1) Complete signal transmission between relay and contactor, 3) Fault detection unit 1 in relay. 4) The signal receiving unit 1 and the signal input unit 2 of the relay are provided with switch indicators. 5) The protection circuit can be connected to the relay protection device 2-7 A/D, and 3) it can directly control the relay and contactor on the relay protection device to realize action. 6) It has flicker free display function. 7) It has manual, automatic, manual/automatic+manual signal input mode (i.e. manual input signal) and alarm mode.It is necessary to select the starting performance of relay according to the actual situation of electric power industry. In some operation situations, the action current of starting relay shall meet the safety requirements. However, in some cases, excessive relay action current will cause the coil to be overheated and burned. Therefore, appropriate starting current shall be selected.The action characteristics depend on the use status of the relay and the operation status of the external circuit. (2) Action capability level: the action capability level of the relay reflects the maximum speed of the relay in practical application, that is, the maximum speed of the relay under various working conditions and the maximum total power that the relay can withstand (dB). (3) Reset characteristics: reset characteristics are related to the current size and contact position of the relay during normal operation. (4) Action time characteristics: generally used to measure whether the relay action time meets its required time. In order to ensure that the action time of the relay meets the requirements, it is necessary to calculate the sum of the time of multiple continuous actions, multiple actions and multiple continuous action segments. (5) Contact characteristics: relay contact characteristics are comprehensive measurements that determine whether any kind of mechanical equipment can effectively withstand mechanical load and current, contact position, contact speed and contact mode during operation.When the input voltage and current are unstable, the relay will be disconnected or short circuited. In case of short circuit or disconnection, the output voltage of the relay will drop to the level before disconnection. The relay will be damaged when the current is output.GE relay is a digital signal, and there are three signal input modes between the input end and the output end. When the switching element fails, the dual power input mode is adopted, and when the relay protection device starts, the relay protection circuit is adopted to output signals. As shown in Figure 4, when a switching element fails, the input terminal will send an output signal to the control relay circuit, and the control relay will act.
