Electronic superconducting solid state relay

Abstract

The invention discloses an electronic superconducting solid state relay. The electronic superconducting solid state relay includes an auxiliary power supply circuit, a wide voltage constant current drive circuit, a timing control circuit, an automobile relay and a solid state relay; aiming at the defects in the prior art Designed, a new type of super solid state relay that combines electronic devices and relays. It has the following characteristics: 1. It is easy to install, does not generate heat and does not require a heat sink, and takes up less space; 2. Its own energy consumption is small (less than 2.5W); 3. It has a wide range of applications (AC version, control voltage AC and DC 7-450V. DC version control voltage 3 ‑60V); 4. You can directly use the start and stop buttons to control the main circuit without auxiliary power supply; 5. The anti-overload ability is twice the rated current.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to an electronic superconducting solid-state relay. Background technique [0002] Solid State Relay (SOLIDSTATERELAYS), abbreviated as "SSR", is a new type of non-contact switching device composed entirely of solid-state electronic components. , can achieve the purpose of connecting and disconnecting the circuit without contact and spark, so it is also called "non-contact switch". It came out in the 1970s and is widely used due to its non-contact working characteristics It is widely used in many fields such as industrial control, electric control and computer control. [0003] The solid state relays seen in the market at present have the following defects. Poor anti-overload ability, large energy consumption, need to add a large enough heat dissipation device to ensure safe operation, and not wide enough application range, etc. [0004] The energy consumption of ord...
