As a tool of information and data communication, computer network has become the technical pillar of the information age, which has changed the appearance of human production and social life.It has a profound impact on various industrial fields, but also provides a strong means of communication for various industrial fields.So far, except differential protection and pilot protection, all relay protection devices can only reflect the electrical quantity at the protection installation site.
It is one of the most important components in remote control and remote control.During the period of 2023 million, the investment rate of automation market will reach 1.033 billion, which will be promoted by the international research market.
1. Selection of rated working voltage of relay
rated working voltage of relay is the most important technical parameter of relay.When using the relay, the working voltage of the circuit (i.e. the circuit where the relay coil is located) should be considered first, and the rated working voltage of the relay should be equal to the working voltage of the circuit.Generally, the working voltage of the circuit is 0.86 of the rated working voltage of the relay.Do not burn out the rated voltage of the relay.In addition, some integrated circuits, such as NE555 circuit, can directly drive the relay to work, while some integrated circuits, such as COMS circuit, have a small output current and need to add a transistor amplifier circuit to drive the relay. Therefore, it should be considered that the output current of the transistor should be greater than the rated working current of the relay.
