Problems solved by technology

[0005] In addition, in the traditional power supply mode, the connection mode of plug and socket is very common, but the socket does not check the load status connected to the plug. This solution provides a method that can detect the load status, which can Effectively avoid the occurrence of short circuit

Embodiment Construction

[0030] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0031] The embodiment of the invention provides a relay switch circuit with no arc and long service life. figure 1 The circuit structure of this arc-free and long-life relay switching circuit is shown. see figure 1 , The relay switch circuit with no arc and long life includes: thyristor switches and relay switches connected in parallel.

[0032] The reason why the thyristor switch and the relay switch are connected in parallel is to eliminate the arc interference when the relay is turned on and off by controlling the opening and closing sequence between the thyristor switch and the relay switch, and prolong the service life of the relay.

Abstract

The embodiment of the invention provides a relay switch circuit and a controller with no arc and long service life. The circuit includes: a relay switch, and a thyristor switch connected in parallel with the relay switch, and the thyristor switch is triggered by a trigger signal synchronized with the synchronous signal. The application of the thyristor switch, the synchronous signal and the trigger signal can control the output voltage, thereby realizing the judgment of the load state. The arc-free and long-life relay switching circuit and the controller provided by the embodiments of the present invention can eliminate the arc interference at the moment when the relay is turned on and off, prolong the service life of the relay, and judge the load state.

Description

technical field [0001] The invention relates to the field of electrical and electronic technology, in particular to a relay switch circuit and a controller with no arc and long service life. Background technique [0002] In today's electrical age, in the control of many electrical appliances, the most commonly used method is to use mechanical switches such as relays and contactors to control the on-off of electrical appliances. Frequently used relays are used as electronic output devices, and their service life and reliability are also an unavoidable topic. [0003] Regarding the life of the relay, it actually includes two issues, namely, the mechanical life and the electrical life. Generally, the number of switching times of the relay without load is 10 million times, which is called the mechanical life. The electrical life is the number of switching times under rated load conditions, generally rated as 100,000 times, which is called the electrical life. [0004] We will ...
