Relay use introduction

Relays are a kind of control equipment commonly used in our lives. In the popular sense, they are switches, and they may be closed or closed when conditions are satisfactory. The switching characteristics of relays are widely used in many control systems, especially discrete control systems. From another point of view, because the electronic circuit used for a certain purpose is ultimately required to interact with some mechanical device, the relay also functions as an interface between the electronic device and the mechanical device.

Intermediate relays commonly used in control are generally used for relay control, signal transmission, and blocking amplification. In addition there are current relays used to confine the current, voltage relays used to manipulate voltage, static voltage relays, phase sequence voltage relays, phase sequence voltage difference relays, frequency relays, power direction relays, differential relays, grounding relays, motor maintenance relays, etc. Wait. It is with these different types of relays that we can control different physical quantities and end up with an intact control system.

In addition to the traditional relays, the relay's skills are also used in other aspects. For example, the motor intelligent maintainer is based on the principle of operation of the three-phase communication motor, and analyzes the causes of the motor damage. It is a common plan. The multi-purpose maintenance device with reliable operation can block the power supply in time when the fault occurs and facilitate the maintenance and maintenance of the motor. This product has the functions of phase-to-phase maintenance, short-circuit and overload maintenance, and is suitable for all kinds of communication motors, switchgear, and distribution. The electrical boxes and other electrical equipment for security maintenance and limited power control, is a variety of electrical equipment planning equipment preferred complementary products. The skill device scale, wiring method, and current adjustment are the same as those of the same type of bimetal thermal relay. It is a leading electronic product that directly replaces the replacement of bimetal chip thermal relays. And its real principle is relay skills.
