Description
技术领域 technical field
本实用新型属于电力检测领域，具体地说是涉及一种电力传输温度检测系统。 The utility model belongs to the field of electric power detection, in particular to a power transmission temperature detection system.
背景技术 Background technique
电力传输检测系统，是针对550kV、220kV、10kV及10kV以下变电站中，变压器、电抗器、断路器、隔离开关、避雷器、进出线母线接头、汇流母排接头、高压开关柜触头等设备及其相关部位，长期运行往往会因承载电流过大或表面氧化等原因造成电阻值增大引起温度升高。如果得不到及时处理可能会使绝缘部件性能降低，导致输电设备绝缘击穿，引起事故发生，给用户带来经济损失。当前许多变电站中，高压输配电设备温度测量，普遍采用的是红外点温计或红外成像温度仪进行检测，上述这些检测装置效率低、实时性差，检测人员的劳动强度大，检测结果与检测人员职业素养有很大关系，更有甚者有些设备的关键部位无法检测，测量精度易受干扰，存在测量信息无法直观显示等缺陷。 The power transmission detection system is aimed at transformers, reactors, circuit breakers, isolating switches, lightning arresters, incoming and outgoing busbar connectors, busbar connectors, high-voltage switchgear contacts and other equipment in substations of 550kV, 220kV, 10kV and below 10kV and their Relevant parts, long-term operation often cause the temperature to rise due to the increase of the resistance value due to excessive carrying current or surface oxidation. If it is not treated in time, the performance of insulating components may be reduced, leading to insulation breakdown of power transmission equipment, causing accidents, and bringing economic losses to users. At present, in many substations, infrared spot thermometers or infrared imaging thermometers are commonly used for temperature measurement of high-voltage power transmission and distribution equipment. The above-mentioned detection devices have low efficiency and poor real-time performance. The professionalism of personnel has a lot to do with it. What's more, some key parts of the equipment cannot be detected, the measurement accuracy is easily disturbed, and there are defects such as the measurement information cannot be displayed intuitively.
专利号为201120176621.7的实用新型，也提供了一种电力传输温度检测系统，但是它仅仅将测温装置（干湿球）采集的温度值作为唯一的技术参数。而在实际中，变电站、变压器、电抗器、断路器、隔离开关、进出线母线、汇流母线、高压开关柜触头等电气设备，由于环境影响，会产生一定的湿度：一方面，水汽的蒸发会对温度检测产生一定的影响，所以该测温装置测得的温度值与实际温度不一致；另一方面，湿度对电气设备也是大大不利的，这将缩短电气设备的使用寿命。所以，该技术方案检测得到的温度值是不准确的。 The utility model with the patent number 201120176621.7 also provides a power transmission temperature detection system, but it only uses the temperature value collected by the temperature measuring device (wet and dry bulb) as the only technical parameter. In practice, electrical equipment such as substations, transformers, reactors, circuit breakers, isolating switches, incoming and outgoing busbars, confluence busbars, contacts of high-voltage switchgear, etc., will generate a certain humidity due to environmental influences: on the one hand, the evaporation of water vapor It will have a certain impact on temperature detection, so the temperature measured by the temperature measuring device is inconsistent with the actual temperature; on the other hand, humidity is also greatly detrimental to electrical equipment, which will shorten the service life of electrical equipment. Therefore, the temperature value detected by this technical solution is inaccurate.
