| Finder relay is an automatically operated electrical appliance that inputs electrical quantities such as voltage, current, and frequency to the relay; When non electrical quantities such as temperature, pressure, and speed reach the specified values, the contacts of the Finder relay will connect or disconnect the controlled or protected circuit. Relays are widely used in motor control and power system protection systems. Finder relays are generally composed of two parts: an input sensing mechanism and an output executing mechanism. The former is used to reflect the level of input, while the latter is used to connect or disconnect circuits. There are many types of Finder relays, which are generally classified as follows: According to the physical properties of the sensing mechanism input, it can be divided into control relays and protection relays. According to the action time, it can be divided into instantaneous relays and delay relays. According to the characteristics of the actuator, it can be divided into contact relays and contactless relays. According to their working principles, they can be further divided into electromagnetic relays, mechanical relays, thermal relays, and semi conductive relays. |
