Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] Embodiment of the gas state monitoring device:

[0037]The gas state monitoring device includes a processor module, a data transmission module and a dormancy wake-up trigger module. Wherein, the processor module is provided with a port for receiving the detection signal of the gas parameter acquisition module installed in the contact chamber of the high-voltage switchgear, and is connected to the gas parameter acquisition module through the detection signal port. The processor module is a long sleep module, which is always in a sleep state when there is no abnormality in the gas parameters, that is, the gas state information, and wakes up when it detects that the gas parameters may be abnormal. The data transmission module is connected with the signal output terminal of the processor module, and is used for transmitting gaseous body parameter data and...

Abstract

The invention relates to a high-voltage switch gear and a gas state monitoring device thereof. The gas state monitoring device comprises a processor module, a data transmission module and a sleep awakening trigger module, wherein the processor module is a long-sleep module, and is provided with a signal input end for receiving detection signals of a gas parameter acquisition module and a signal output end for making connection with the data transmission module; the sleep awakening trigger module is provided with a port for receiving the detection signals of the gas parameter acquisition module; and the output end of the sleep awakening trigger module is connected with an awakening trigger end of the processor module, and used for triggering and awakening the processor module when the gas state signal change exceeds the set threshold. When the gas parameter data greatly changes, the sleep awakening trigger module triggers the processor module from the sleep state to the operating state, thereby effectively lowering the energy consumption of the processor module in the high-voltage switch gas state monitoring process, and correspondingly enhancing the energy utilization efficiency of the processor module.

Description

technical field [0001] The invention relates to a high-voltage switchgear and a gas state monitoring device thereof, belonging to the technical field of gas monitoring. Background technique [0002] At present, the condition-based maintenance of power equipment is being vigorously promoted in China. High-voltage switchgear is an important component of the power system, and its equipment reliability has a crucial impact on the reliability of the power system operation. SF 6 Gas is widely used in high-voltage switchgear due to its electrical insulation and excellent arc extinguishing performance. However, SF 6 Factors such as gas state such as pressure, temperature, density and humidity will directly affect the operating performance of high voltage switchgear. In order to ensure the stable operation of power equipment, it is necessary to control the SF in high-voltage switchgear 6 Real-time monitoring of gas status. [0003] In order to realize SF in high voltage switchgea...
