Abstract

The invention discloses a three-phase electronic superconducting solid state relay. The three-phase electronic superconducting solid state relay includes an auxiliary power supply circuit, a wide voltage constant current drive circuit, and a timing control circuit. The three groups are composed of an automobile relay and a solid state relay. Solid state relay circuit one, two, three, and phase loss protection detection circuit. This technical solution is designed for the defects in the prior art, and has the following characteristics: 1. It is easy to install, does not generate heat, does not require a cooling device, and takes up less space. 2 Its own energy consumption is small (less than 7.5W). 3 Wide range of applications (AC version, control voltage 7-450V; DC version, control voltage 3-60V). 4. The start and stop buttons can be used directly to control the main circuit without auxiliary power supply. 5. Increase the input phase loss protection function to effectively ensure the safe operation of electrical equipment.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to a three-phase electronic superconducting solid state relay. Background technique [0002] Solid state relay (SOLIDSTATE RELAYS), abbreviated as "SSR", is a new type of non-contact switching device composed of solid-state electronic components, which uses the switching characteristics of electronic components (such as switching transistors, bidirectional thyristors and other semiconductor devices) , 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. Electronic control and computer control have been increasingly widely used. The solid-state relays currently on the market have the following defects, such as poor overload resistance, high energy consumption, need to add a large enough cooling device to ensure safe operation, and not wide enough application r...
