Abstract

The invention discloses a novel bus relay. The novel bus relay comprises a power supply, a single chip microcomputer control system, a driving system, a detecting system, a load, a bus interface and a bus; and the driving system further comprises a test circuit, a control circuit and a shift switch. Compared with the prior art, the novel bus relay has the beneficial effects that control circuit can only drive the relay to pull in when the voltage output by an AC / DC rectifying module reaches a set value, so that the main contact jitter of the relay is reduced, and the effective pulling in of the main contact of the relay is ensured; meanwhile, the relay is mounted by the bus, so that the usage amount of cables in a power distributing system is reduced; the distributed installation, the debugging and the maintenance of the relay can be realized conveniently; and in addition, the driving system avoids the generation of arc and unstable output voltage when the relay is switched, so that the novel bus relay is quite wide in the application prospects.

Description

technical field

[0001] The invention relates to a relay, in particular to a novel bus relay, and belongs to the technical field of low-voltage switchgear and control equipment. Background technique

[0002] Relay (English name: relay) is an electrical control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automatic control circuits, it is actually an "automatic switch" that uses small currents to control large current operations, so it plays the role of automatic adjustment, safety protection, and conversion circuits in the circuit.
