Abstract

The invention discloses an arc light protection device which comprises an arc light probe which is used for collecting arc light generated during short circuit discharge of a bus joint and further exciting the arc light to be fluorescence for outputting, or used for detecting visible light generated by ambient light leakage and outputting the visible light; an optical fiber which is connected withthe arc light probe through a connector and is used for transmitting the fluorescence or visible light output by the arc light probe, and a control terminal which is communicated with the optical fiber through the connector, and the fluorescent light and / or the visible light transmitted by the optical fiber is input into the control terminal, When the control terminal identifies that fluorescentlight and / or the visible light is caused by short circuit discharge of the bus joint or by ambient light leakage, a power supply protection bus is cut off or an alarm signal of a protection system fault is sent respectively. The device provided by the invention has all functions of a traditional arc light protection system, and all advantages of a traditional device are maintained. The stability of the arc light protection device is improved, so that the arc light protection device is more suitable for a power system.

Description

technical field [0001] The invention belongs to the technical field of arc light protection systems, and in particular relates to an arc light protection device. Background technique [0002] The intelligent arc protection system is based on the principle that arc discharge will occur after a short circuit occurs in the switchgear. The arc probe connected to the optical fiber is installed at the bus joint. Once a short circuit occurs, the probe senses the arc discharge and transmits the corresponding optical signal through the optical fiber. When it is transmitted to the control terminal, the system can cut off the power supply as soon as a few milliseconds after the bus short circuit, so as to ensure the safety of personnel and reduce equipment loss. In addition to the fast response speed, the optical probe of the arc protection system and the control end are connected by an insulated optical fiber. The strong electromagnetic interference when the bus is short-circuited is ...
