Description

一种利用闪络取能的智能故障报警绝缘子An Intelligent Fault Alarm Insulator Utilizing Flashover Energy Harvesting

技术领域technical field

本发明属于绝缘子在线监测领域,涉及一种利用闪络取能的智能故障报警绝缘子。The invention belongs to the field of on-line monitoring of insulators, and relates to an intelligent fault alarm insulator utilizing flashover to obtain energy.

背景技术Background technique

绝缘子是一种特殊的绝缘控件,在架空输电线路中承担增加爬电距离、支撑或悬挂的任务,在电力系统中具有非常重要的地位,其安全可靠运行对整个电网的安全稳定起着关键性作用。Insulator is a special insulation control, which undertakes the task of increasing creepage distance, supporting or hanging in overhead transmission lines. It plays a very important role in power system, and its safe and reliable operation plays a key role in the safety and stability of the entire power grid. effect.

绝缘子广泛应用于电力系统中。据估计,我国目前110kV以上复合绝缘子挂网运行的数量已超过500万支,另外还有大量电瓷、玻璃绝缘子。绝缘子的寿命最高为30年,一般运行10年以上的绝缘子,因为闪络、老化等原因,其绝缘性能、憎水性能都会下降。每年都有数以十万计的绝缘子损坏或退役。Insulators are widely used in power systems. It is estimated that the number of composite insulators above 110kV in operation in my country has exceeded 5 million, and there are also a large number of electric porcelain and glass insulators. The maximum lifespan of an insulator is 30 years. Generally, insulators that have been in operation for more than 10 years will have reduced insulation performance and water-repellent performance due to flashover, aging and other reasons. Hundreds of thousands of insulators are damaged or decommissioned every year.

固体绝缘子周围的气体或液体电介质被击穿时,沿固体绝缘子表面放电的现象称为闪络。发生闪络后,电极间的电压迅速下降到零或接近于零。闪络通道中的火花或电弧使绝缘表面局部过热造成炭化,损坏表面绝缘。在高压系统中,湿闪、污闪事故不断,闪络事故涉及面广、停电时间长、经济损失大、严重影响电力系统的正常运行。发生过闪络的绝缘子,其绝缘表面被破坏,随之表面绝缘性能下降,闪络电压降低,寿命缩减甚至失效,危害电力系统的运行甚至造成更大的电力事故。When the gas or liquid dielectric around the solid insulator is broken down, the phenomenon of discharge along the surface of the solid insulator is called flashover. After a flashover occurs, the voltage between the electrodes drops rapidly to zero or close to zero. Sparks or arcs in the flashover channel cause local overheating of the insulating surface and cause carbonization, which damages the surface insulation. In the high-voltage system, wet flashover and pollution flashover accidents continue, and flashover accidents involve a wide range of areas, long power outages, large economic losses, and seriously affect the normal operation of the power system. The insulating surface of the insulator that has flashover is damaged, and then the surface insulation performance decreases, the flashover voltage decreases, the life is shortened or even fails, which endangers the operation of the power system and even causes a greater electrical accident.

为了提高绝缘子的可靠性,需要对绝缘子进行检修、维护和寿命预测。现行的电力系统绝缘子检修和维护工作,由检修人员携带检测装置,逐个检测绝缘子性能,这种定期的被动性预防检测方式,盲目而且工作量大。绝缘子电气性能的下降,伴随运行年限的增长,受自然环境日晒、雨淋、气候变化及化学物质的腐蚀的影响原因外,闪络是另一主要原因。因此,及时得知绝缘子是否发生闪络,是绝缘子在线监测的重要内容,能够对绝缘子检修和维护、绝缘子寿命预测具有极重要的数据参考价值。对绝缘子寿命的合理评估,能够提高绝缘子使用效率,减少因绝缘子故障造成的电力系统的损伤,具有巨大的经济效益。In order to improve the reliability of insulators, overhaul, maintenance and life prediction of insulators are required. In the current inspection and maintenance of insulators in power systems, maintenance personnel carry detection devices to test the performance of insulators one by one. This regular passive preventive detection method is blind and heavy workload. The decline of the electrical performance of the insulator is accompanied by the increase of the service life, which is affected by the sun, rain, climate change and corrosion of chemical substances in the natural environment. Flashover is another main reason. Therefore, timely knowing whether an insulator has flashover is an important part of on-line monitoring of insulators, and it can have extremely important data reference value for insulator repair and maintenance, and insulator life prediction. Reasonable evaluation of insulator life can improve the efficiency of insulators and reduce damage to power systems caused by insulator failures, which has huge economic benefits.
