Abstract

The invention provides a transformer substation environment monitoring system. The transformer substation environment monitoring system comprises a controller, an SF6 gas transmitter, an oxygen transmitter, a draught fan and an alarm, wherein a preset SF6 gas concentration value and a preset oxygen concentration value are stored in the controller in advance. The controller obtains a current SF6 gas concentration value detected by the SF6 gas transmitter in real time and compares the current SF6 gas concentration value with the preset SF6 gas concentration value, and when the current SF6 gas concentration value is higher than the preset SF6 gas concentration value, the controller starts the draught fan to conduct air exhausting and ventilation and controls the alarm to give an alarm at the same time. In the same way, the controller obtains a current oxygen concentration value detected by the oxygen transmitter in real time and compares the current oxygen concentration value with the preset oxygen concentration value, and when the current oxygen concentration value is lower than the preset oxygen concentration value, the controller starts the draught fan to conduct air exhausting and ventilation and controls the alarm to give an alarm at the same time. According to the transformer substation environment monitoring system, leakage of SF6 gas can be timely discovered, and therefore the personal safety can be ensured.

Description

technical field [0001] The invention relates to the technical field of environment monitoring, and more specifically, relates to a substation environment monitoring system. Background technique [0002] SF 6 Because of its excellent insulation and arc extinguishing properties, gas is widely used in medium-voltage, high-voltage and ultra-high voltage switches, so its safety has also received widespread attention. Normal SF 6 The gas is an inert gas that is colorless, odorless, denser than air, difficult to mix with air, and has no toxicity to the human body. But under the action of high voltage arc, SF 6 Partial decomposition of the gas occurs, and its decomposition products are often highly toxic, even in trace amounts, and can be fatal. When using SF 6 When the indoor switch with gas as the insulation and arc extinguishing medium leaks during use, the leaked SF 6 The gas and its decomposition products will accumulate in the lower indoor space, causing local hypoxia an...
