Introduction to the classification of power detection equipment relays Power detection equipment relays are actually used in our daily life to control the size of the current.“automatic switch”, it is an electrical control device, which is an electrical appliance that makes a predetermined step change of the controlled quantity in the electrical output circuit when the change of the input quantity meets the specified requirements. The relay has a connection between the control system and the controlled system. interaction. Because it plays the role of automatic adjustment, safety protection, conversion circuit, etc. in the circuit, it is usually used in the automatic control circuit. 1. Reed relay: a relay that is sealed in the tube and has the dual functions of an electric shock reed and an armature magnetic circuit to open, close or switch circuits. 2. High frequency relay: It is used to switch high frequency and radio frequency circuits Minimal loss relay.
3. Polarized relay: a relay that has a combined action of a polarized magnetic field and a control current through the magnetic field generated by the control coil. The direction of action of the relay depends on the direction of the current flowing in the control coil. 4. Electromagnetic relay: It is an electrical relay that uses the suction effect generated by the circuit in the input circuit between the electromagnet core and the armature.
5. Time relay: when the input signal is added or removed, the output part needs to delay or limit the time to close or disconnect the controlled circuit relay. 6. Solid state relay: refers to a kind of relay whose input and output are isolated in which electronic components perform their functions without mechanical moving components. 7. Temperature relay: a relay that acts when the outside temperature reaches a given value.
8. Other types of relays: such as photorelays, acoustic relays, thermal relays, instrument relays, Hall effect relays, differential relays, etc. The classification of relays introduces power testing equipment Shenzhen Noyafa Electronic Technology Co., Ltd.
