Description

一种高压套管油气远程监测***A high-voltage casing oil and gas remote monitoring system 技术领域Technical field
本发明属于电力在线监测技术领域，具体涉及一种高压套管油气远程监测***。The invention belongs to the technical field of electric power online monitoring, and specifically relates to a high-voltage casing oil and gas remote monitoring system.
背景技术Background technique
高压套管作为变压器箱外的主要绝缘装置，其绝缘状态对变压器安全运行至关重要。随着变压器电压等级的升高，套管故障或损坏引起的电力事故频繁发生。套管两端施加的是高压母线，在高压作用下，由于套管绝缘结构中如油纸绝缘是由高聚合碳氢化合物组成，碳氢键能较低，在分解过程中最先产生氢气，同时套管长期暴露在外界中容易受到环境影响，当套管内部受潮导致绝缘介质中含水量的增加，在电场作用下，也会电解产生氢气，氢气是套管油中气体的主要成分。High-voltage bushings are the main insulation device outside the transformer box, and their insulation status is crucial to the safe operation of the transformer. As the voltage level of transformers increases, power accidents caused by bushing failure or damage occur frequently. High-voltage busbars are applied to both ends of the bushing. Under the action of high voltage, because the insulation structure of the bushing, such as oil-paper insulation, is composed of highly polymerized hydrocarbons, the carbon-hydrogen bonding energy is low, and hydrogen is first produced during the decomposition process. The casing is easily affected by the environment when exposed to the outside world for a long time. When the inside of the casing becomes damp, the water content in the insulating medium increases. Under the action of the electric field, hydrogen will also be electrolyzed to produce hydrogen. Hydrogen is the main component of the gas in the casing oil.
当套管发生局放、过热、受潮等故障时，伴随着内部产生的特征气体增加，套管内压强、油温也发生明显变化。因此通过对油的基本特性以及特征气体含量的综合监测，可以为少油设备的故障诊断提供更全面的监测数据。When the casing fails such as partial discharge, overheating, or moisture, the pressure and oil temperature inside the casing will also change significantly as the characteristic gas generated inside increases. Therefore, through comprehensive monitoring of the basic characteristics of oil and characteristic gas content, more comprehensive monitoring data can be provided for fault diagnosis of oil-less equipment.
但是，目前高压套管油气状态多采用油色谱检测方法，但此方法试验周期长，检测量单一，套管内部油量少，由于需要现场实地取油检测导致取油时需停电，带电检测有效性差，缺乏有效可靠的在线监测手段，因此急需一种可远程监控高压套管油气状态的监测***。However, at present, the oil chromatography method is mostly used to detect the oil and gas status of high-voltage casings. However, this method has a long test cycle, a single detection amount, and a small amount of oil inside the casing. Due to the need for on-site oil detection, a power outage is required when taking oil, and live detection is effective. The performance is poor and there is a lack of effective and reliable online monitoring methods. Therefore, there is an urgent need for a monitoring system that can remotely monitor the oil and gas status of high-voltage casings.
