Embodiment 1

[0036] An automatic fire detection method for an outdoor reactor in a substation, comprising the following steps:

[0037] S1, setting LED lights and monitoring cameras on both sides of the reactor, the LED lights and monitoring cameras are respectively connected to the controller through communication;

[0038] S2, the controller controls the LED lights to emit lights of different colors according to a certain frequency change;

[0039] S3, the light emitted by the LED lamp is collected by the monitoring camera after passing through the reactor, and the monitoring camera sends the collected light signal to the controller;

[0040] S4, the controller compares the received light signal with the light signal emitted by the LED light, and judges whether a fire has occurred in the reactor.

[0041] Specifically, in step S1, wireless communication is realized between the controller and the LED lamp through an RS485 communication module; communication between the controller and the...

Embodiment 2

[0059] Such as image 3 As shown, this embodiment provides an automatic fire detection device for outdoor reactors in substations, including a controller 1, a visible light signal generator 2 and a visible light signal detector 3 connected in communication with the controller 1; the controller 1 It is used to control the visible light signal generator 2 to emit visible light of different colors according to a certain frequency change, and is also used to receive the visible light signal detected by the visible light signal detector 3; the visible light signal generator 2 and the visible light signal detector 3 are paired It is arranged on both sides of the reactor 4, and the visible light signal generator 2 and the visible light signal detector 3 are directly facing the horizontal line higher than the upper surface of the reactor 4 by 0 to 20 cm.

[0060] Specifically, wireless communication is realized between the controller 1 and the visible light signal generator 2 through ...

Abstract

The invention discloses a method and device for automatic fire detection of an outdoor reactor in a substation. The method includes the following steps: firstly, a visible light signal generator and a visible light signal detector are respectively arranged on both sides of the reactor, and then the visible light signal generator is controlled by a controller according to the following steps: A certain frequency changes to emit visible light of different colors. The visible light emitted by the visible light signal generator passes through the reactor and is collected by the visible light signal detector. The visible light signal detector sends the collected visible light signal to the controller; the controller finally receives The visible light signal of the reactor is compared with the visible light signal emitted by the visible light signal generator to judge whether the reactor is on fire; the invention has a simple structure and is easy to install, and can effectively monitor the fire of flammable electrical equipment side by side outdoors for a long time.

Description

technical field [0001] The invention belongs to the field of monitoring and communication of electric power systems, in particular to an automatic fire detection method and device for an outdoor reactor of a substation. Background technique [0002] Reactors are indispensable key equipment in power systems. Reactors used in EHV / UHV application scenarios have high voltage and large capacity, and have higher performance indicators and related technologies such as response speed, harmonic content, and reliability. Require. With the increase in the number of dry-type reactors put into operation, due to the uneven product quality and the impact of bad weather on the equipment, reactor operation failures occur frequently. The operating equipment seriously affects the safe and stable operation of the power system. At present, there is still a lack of effective and low-cost detection methods or devices for this type of fire detection. If the fire phenomenon in the early stage of e...
