A DC distributed energy intelligent lighting circuit electrical protection device

Abstract

The invention relates to the technical field of electrical equipment, and discloses a DC distributed energy intelligent lighting circuit electrical protection device, which includes a housing, a static contact, a moving contact and a compression spring, and the static contact is fixedly connected to the housing , the movable contact is movably connected with the housing through a compression spring. The electrical protection device of the DC distributed energy intelligent lighting circuit separates the static contact and the movable contact through the quick insertion of the insulating sheet, and then realizes the control of the on-off between the static contact and the movable contact, because the control current is only in the drive It works instantly, so when the control current is unstable due to equipment failure, it can also ensure the normal operation of the relay and improve the reliability of its operation. Secondly, the distance between the static contact and the moving contact is relatively close, and the separation and contact The arc is formed more quickly, and the arc formation time is shorter, which further reduces the destructive power of the arc. On the other hand, the insertion of the insulating sheet can ensure the separation of the static contact and the moving contact, and completely prevent the occurrence of adhesion.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an electrical protection device for a DC distributed energy intelligent lighting circuit. Background technique [0002] Distributed energy is an energy supply method built on the user end, that is, installing small-scale, small-capacity, and modular energy systems on decentralized user ends, including solar energy utilization, wind energy utilization, fuel cells, and gas cooling, heating, and electricity. For a variety of forms. [0003] The DC distributed energy smart lighting circuit obtains the basic data and dynamic data of distributed energy and lighting equipment through the perception layer of the Internet of Things, and performs intelligent control such as monitoring, control and scheduling at the application layer to maximize resource utilization. [0004] Fluorescent lamps are commonly used lighting equipment, and fluorescent lamps need to break down the g...

Problems solved by technology

[0005] The relay usually includes a moving contact and a static contact. The action current drives the static contact to move to make it close or open. Generally, when there is no current, it is called a normally closed contact relay, and when it is open, it is called a normally open contact relay. Contact relay, it can be seen that the normally closed contact relay requires current to maintain its open state, and the normally open contact relay requires current to maintain its closed state. In the lighting circuit, the opening and closing time of many positions are almost the same Long, one of the states requires power to maintain, which increases energy consumption and reduces reliability

[0006] Secondly, when the relay is disconnected and closed, when the static and moving contacts are moving away from and approaching, arcing phenomenon will occur, which will cause contact welding and ablation, contact pair adhesion, unreliability, poor contact and wear Too fast and other phenomena, reducing the service life of the relay
