Embodiment 1

[0032] like Figure 1 to Figure 4 As shown, the present invention includes a remote control device, a running device and a gas directional leak detection device arranged on the running device, and the remote control device includes a signal receiving module 8, a first control module 9 and a signal processing module 10 electrically connected in sequence;

[0033] The gas directional leak detection device includes an infrared detection module, an ultrasonic detection module, a second control module 1 and a signal transmission module 2. The infrared detection module includes an infrared transmission module 3, an infrared reflector 4 and an infrared receiving and processing module 5. The ultrasonic detection module includes an ultrasonic Transmitting module 6 and ultrasonic receiving processing module 7, the output end of infrared receiving processing module 5 and ultrasonic receiving processing module 7 are electrically connected with the input end of second control module 1 respe...

Embodiment 2

[0036] The structure of this embodiment is basically the same as that of Implementation 1. The difference is that the walking device is placed on the GIS equipment site for long-term use, and the signal sending module 2 and the signal receiving module 8 communicate through the communication module 11, and the communication module 11 is a ZigBee communication module. , the infrared detection module and the ultrasonic detection module adopt intermittent work to improve the working stability and service life of the sensor. The output end of the first control module 9 is also electrically connected to the alarm module 23, and the alarm module 23 adopts an audible and visual alarm. The output end of the control module 1 is also electrically connected to the exhaust fan (not shown in the figure) on the site of the GIS equipment.

Embodiment 3

[0038] The structure of this embodiment is basically the same as that of implementing one, and the difference is: a camera module 24 is set on the support 16, and the input end of the camera module 24 is connected with the third control module 21, and the camera module 24 sends the real-time video signal of the scene to the third control module 21. Three control modules 21, the third control module 21 sends the video signal to the first control module 9, and displays it to the on-site management personnel through the signal processing module 10. This structural design is conducive to observing the real scene of the air leakage on site, especially for the location of the air leakage provide a basis for judgment.

Abstract

The invention discloses a leak detection robot for SF6 gas in a substation GIS equipment, which comprises a remote control device, a walking device and a directional leak detection device for the gas arranged on the walking device. The directional leak detection device for the gas comprises an infrared detection module, an ultrasonic detection module, a second control module and a signal transmitting module. The infrared detection module comprises an infrared transmitting module, an infrared reflecting plate and an infrared receiving and processing module. The ultrasonic detection module comprises an ultrasonic transmitting module and an ultrasonic receiving and processing module. Output terminals of the infrared receiving module and the ultrasonic receiving and processing module are respectively electrically connected with an input terminal of the second control module. The ultrasonic detection module and the infrared detection module are arranged on the walking device, so that the leak detection robot for the SF6 gas in the substation GIS equipment not only can detect the leakage of the SF6 gas in time, but also can detect the concentration of the SF6 after the leakage, so as to guarantee safety of personal and equipment to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of automatic detection, and in particular designs a SF6 gas leak detection robot for substation GIS equipment. Background technique [0002] SF6 gas has a history of one hundred years. It is an artificial inert gas synthesized by two French chemists, Moissan and Lebeau in 1900. Around 1940, the US military used it for the Manhattan Project (nuclear military). Commercially available in 1947. Currently SF6 gas is mainly used in the power industry. SF6 gas is used in 4 types of electrical equipment as insulation and / or arc extinguishing; SF6 circuit breakers and GIS (here refers to sulfur hexafluoride closed combination electrical appliances, internationally known as "gas insulated switchgear" (GasInsulated Switchgear) , SF6 load switchgear, SF6 insulated transmission pipelines, SF6 transformers and SF6 insulated substations, 80% of which are used for high and medium voltage power equipment. Among them, GIS e...
