Description

一种基于BLE技术的开关柜温度采集系统 Switchgear temperature acquisition system based BLE Technology

技术领域 FIELD

[0001]本发明涉及电气设备技术领域,具体涉及一种基于BLE技术的开关柜温度采集系统。 [0001] The present invention relates to the field of electrical equipment, particularly relates to a switching cabinet temperature acquisition system based BLE technology.

背景技术 Background technique

[0002]高压开关柜在输配电系统中一直都承担着重要作用,包括电力线路的关合、电能的转换、线路故障的保护和监测运行电量数据等重要作用,因此其在电力系统中获得了越来越广泛的应用。 [0002] In the high voltage switchgear transmission and distribution systems have been plays an important role, including the important role of closing the power line, the power conversion circuit fault protection and monitoring operating electric quantity data and the like, so that in the power system more and more widely used.

[0003]根据统计,每年国内都会有很多发电厂、变电系统因为高压开关柜故障的缘故造成巨大的经济损失。 [0003] According to statistics, every year there will be a lot of domestic power plants, high voltage switchgear substation in because the system failure caused huge economic losses. 导致高压开关柜发生故障的主要原因有开关柜部件常年运行引起的老化、产品的质量问题、封闭运行导致的热量集中、开关柜满负荷以至超负荷运行等。 Leading cause of failure of high voltage switchgear are switchgear operating member perennial aging, product quality problems caused by the heat concentration due to closing operation, the switchgear operating at full capacity even overload the like. 而造成高压开关柜故障的最直接的原因就是开关柜内部刀闸的接头与隔离的触头等部位因为产品质量的不合格或者触头的氧化、松动、负荷过大等引起接触电阻增大而引起的发热。 The most direct cause of the failure of high voltage switchgear is isolated from contact with other parts of the joint inside the switchgear because the oxidation of the knife contacts or unacceptable product quality, loose, excessive load caused by the contact resistance increases caused by fever. 封闭的柜体结构使得热量没办法散发出去,这样长久得不到处理最终会引发火灾乃至大规模停电。 It closed cabinet structure so that the heat can not dissipate, so long unaddressed will eventually cause a fire or even large-scale power outages. 因此高压开关柜内部电缆接头和断路器触头等部位的温度必须采取有效手段对其进行监测,以保障开关柜的安全稳定运行。 So High Voltage Switchgear internal cable connectors and circuit breaker contacts and other parts of the temperature must be monitored to take effective measures to ensure safe and stable operation of the switchgear.

[0004]目前常用的高压开关柜测温方法主要包含:示温腊片变色法、红外手持设备测温法、光纤测温法。 [0004] The temperature measurement method of high voltage switchgear currently used mainly comprising: a thermochromic color sheet wax, infrared thermometry handheld device, the optical fiber thermometry. 其中示温腊片变色法在早期高压开关柜和其它电气产品中应用的比较多,而随着电力系统和现代科技的不断进步,已逐渐退出应用市场,目前市场上只有少数场合还在使用这种方法。 Which shows the temperature wax pieces change color method in the early high voltage switchgear and other electrical products in more applications, and with the power system and the continuous progress of modern science and technology, has been excluded from the application market, currently on the market only a few places are still using this method. 红外手持设备测温法这种测温方法是一种非接触式的测温法,测温精度高,但是巡检间隔长,不能及时发现触点温度的变化状况。 This handheld infrared temperature thermometry is a non-contact method of temperature measurement method, temperature measurement with high precision, but the polling interval long, it can not detect the contact condition of temperature change. 目前电力行业红外测温仪市场上适合的产品比如一套美国FSI红外成像的测试系统,价格高至10多万元。 Currently suitable infrared thermometer on the power industry market products such as a United States FSI infrared imaging test systems, high price to 10 million. 除此之外红外测温仪容易受到环境的影响,当存在障碍物时不方便测量其温度数值。 Besides infrared thermometer easily affected by the environment, there is an obstacle when the measured temperature value is inconvenient. 光纤测温法对精度和实时性的要求高,有一定的市场,但是测温系统成本比较高,并且维护困难,不利于大范围的推广应用,新型高压开关柜集成化越来越高、空间越来越狭小的内布置光纤测温系统也越来越困难。 Fiber optic thermometry high demands on precision and real-time, have a certain market, but the temperature measurement system cost is relatively high, and difficult to maintain, is not conducive to the promotion of a wide range of applications, the new High Voltage Switchgear integrated more and more space and more narrow in the arrangement of optical fiber temperature measurement system has become increasingly difficult. 因此设计一种利用无线通信技术对开关柜内部温度数据进行实时采集监测的装置,这对于开关预防性检修有着重要的意义。 Therefore, the design of a device for monitoring the real-time acquisition of the internal temperature of the switchgear data by wireless communication technology, which switches for preventive maintenance is significant.
