Description

避雷器泄漏电流与动作次数实时监测系统 Arrester leakage current and number of operations in real-time monitoring system

技术领域 FIELD

本发明涉及一种避雷器泄漏电流与动作次数实时监测系统。 The present invention relates to an arrester leakage current operation frequency and real-time monitoring system. 特别适用于高压电网、发电厂、变电站和电力设备上的避雷器的在线监测。 Especially for on-line monitoring of the arrester on the high-voltage grid, power plants, substations and power equipment.

背景技术 Background technique

现有的发电厂、变电站内的避雷器在线监测仪,主要用来监视避雷器的泄漏电流及动作次数。 Leakage current and number of operations of existing power plants, the arrester line monitor the substation, it is mainly used to monitor the arrester. 如中国专利ZL93111792.5提供的“避雷器漏电流检测及动作记录器”,它改变了以前避雷器的检测方式,将避雷器的计数器与检测漏电流的毫安表设计成为一整体结构,既可以监测避雷器漏电流变化,又可以在雷击电流作用下计数。 Chinese patent ZL93111792.5 provides a "leakage current detector and the operation of the arrester recorder", it changes the way previously detected arrester, the arrester design milliammeter leak current detection counter becomes a unitary structure, the arrester may be monitored drain current changes, and the lightning current may be counted in the action. 但它必须由值班人员到现场查看,若遇下雨、打雷、大雾等天气多有不便,且易疏忽,一旦出现避雷器受潮、机械缺陷等不良状况也不能及时发现或报警,很难避免事故的发生。 But it must be viewed by the duty officer to the scene, in case of rain, thunder, fog and other weather more than a inconvenience, and easy to negligence, once the surge arresters exposed to moisture, mechanical defects and other adverse conditions can not detect or alarm, it is difficult to avoid accidents happened.

另外避雷器泄漏电流与动作次数在线检测仪器,如上述都只重视信号取样方式及测量原理,只要便于安装和便于用户检查、记录即可。 Further the arrester leakage current operation frequency and line detection equipment, such as the above-described embodiment and only importance sampling signal measuring principle, as long as easy to install and easy for users to check, can be recorded. 用户也只是延续以前的运行、检查和管理模式。 Users also just a continuation of the previous operation, inspection and management. 并未考虑检测装置能否为状态检修提供有效数据及帮助,因为,现有的避雷器在线监测仪器一般都采用指针型仪表加机械或脉冲式计数器,由于不是数字电路,被测数据不能进行就地存储和再利用,又由于监测装置安装于现场,远离集控室,对运行监测、抄表等都非常不方便,特别是一旦有突发事件发生或重要事件判断,其故障数据又无法追述和重演,影响事故的分析和判断。 Detecting means is not considered valid data and suggest assist maintenance state, since the conventional arrester line monitoring equipment is generally used mechanical or pointer-type instrument plus pulse counter, not because digital circuits, data can not be measured in situ storage and re-use, and because the monitoring device is mounted in the field, away from the control room, for operation monitoring, meter reading and so is very inconvenient, especially if there is an important event or emergency occurs is determined that the failure data are unable to recount and repeat the impact of the accident analysis and judgment.

现有的数据采集和监测系统均采用集中测量结构,即将所有的被测信号汇集在一处,由采集装置逐一进行采集测量,也就是常说的巡检测量方式。 Existing data collection and monitoring systems are centralized measurement architecture, all coming together in a measured signal, collected by the collecting means by one measurement, the inspection is often said measurement. 尽管这种巡检方式被广泛采用(如多点温度、电流、电压的监测等),但用于变电站在线监测系统中时,却存在如下几个方面的问题。 Although this inspection mode is widely used (e.g., multi-point temperature, current, voltage monitoring, etc.), but for the online monitoring system substation, but a problem in the following aspects.

1)被测模拟信号的长距离传输问题:因为变电站内存在强烈的工频电磁场干扰,利用屏蔽电缆长距离传输模拟信号,虽然可抑制工频电场的干扰问题,但对工频磁场的干扰却几乎不起作用,这是一个经常被忽视的问题。 1) long-distance transmission of analog signals measured problems: because the substation memory strong frequency electromagnetic interference, a shielded cable for long distance transmission using an analog signal, can be suppressed although the frequency of the interference field, but they work frequency magnetic interference almost does not work, this is an often overlooked problem.

2)无法判断被测设备的真实状况:变电站运行现场,有很多因素会影响系统监测数据准确性和稳定性,除工频干扰因素外,还有如下原因:环境温湿度的变化及表面泄漏电流的影响等。 2) can not determine the true state of the device under test: substation operation site, there are many factors that affect the accuracy and stability of the system monitoring data, in addition to frequency interference factors, there are the following reasons: Changes in temperature and humidity and the surface leakage current the impacts. 这些因素发生变化时,监测数据都会随之发生波动,且无规律可言,而原有的监测系统往往不能正确地进行识别判断,当然也就无法了解被测设备的真实状况。 When these factors change, monitoring data will fluctuate ensued, and no law at all, while existing monitoring systems often can not be identified correctly judge, of course, will not be able to understand the true state of the device under test.

3)运行可靠性差,故障率极高:除了环境温湿度变化造成一些测量误差外,变电站内的变压器或线路的投切操作,往往会产生较强的冲击电流,导致不同的接地点之间存在较高的电位差,也就是人们通常说的“地电位抬高”问题。 3) Run poor reliability, high failure rate: In addition to measurement errors cause some changes in temperature and humidity, the switching operation of the transformer in the substation or lines tend to produce a strong rush current, resulting in contact between different locations the higher the potential difference, that is, people often say "ground lift" problem. 如果监测系统采用“单点接地”方式,可以有效地防止“地电位抬高”对测量部件的不良影响,但由于目前所有的巡检式监测系统需要把多个被测信号从设备运行现场汇集到主机,基于运行安全及抗干扰方面的要求,在工程上往往难以解决电气测量回路的单点接地问题,监测系统在运行中一旦受到“地电位冲击”,瞬间产生的共模电压很可能造成电子器件的损坏。 If the monitoring system uses a "single-point ground connections", can effectively prevent adverse effects "ground elevation" of the measurement section, but because all current inspection systems require the monitoring of formula plurality of signals measured from pooled field operation device single-point grounding problems to the host, based on the requirements of operational safety and interference aspects, the project is often difficult to solve in the electrical measurement circuit monitoring system in operation in the event of "ground attack", the common-mode voltage generated at the moment is likely to result damage to the electronic device. 这就是有些监测系统在实验室中可以很好地运行,而在安装到变电站以后却频繁发生故障(例如电流传感器中的放大电路损坏),即使经过多次维修更换也无法正常运行的原因。 Some monitoring system which is well run in the laboratory, but the frequent failure (e.g. damage amplifying circuit current sensor) mounted to occur after the substation, reasons not work correctly even after repeated repair and replacement.

综上所述,对于一个测量原理正确的在线监测系统,如果没有一个较好的结构形式与之配合,不但会影响监测数据的有效性,在保证系统的运行连续性方面也是较为困难的。 In summary, for a correct measurement principle of on-line monitoring system, if not a better co-ordinated with the structure will not only affect the validity of monitoring data, to ensure continuity in the operation of the system is also more difficult.

在本实施例中,采用AMB-05型传感器(为另一专利技术所提供)。 In the present embodiment, using sensors AMB-05 (provided by another patent). 用于氧化锌避雷器泄漏电流的测量。 MOA for measuring the leakage current. 设计是基于电流互感器(电流耦合器)的工作原理;电流互感器将接收到的大电流变成小电流,经过高速积分器将电流值变成电压值,再经过放大调幅器对其波形进行整形放大后,分别输入到信号跟踪输出器、雷击次数计数器和泄漏电流采集器,记录下的雷击次数和泄漏电流值及时输送到无线数据传输终端。 Design is based on a current transformer (a current coupler) works; current transformer received a large current into a small current, the current through the high speed integrator value into a voltage value, then its waveform amplified modulator after shaping amplified outputs are input to the signal trace, a number of lightning strikes and the counter collector leakage current, lightning strikes, and the leakage current value is recorded in time delivery to a wireless data transmission terminal. 它的优点在于测量范围宽,线性度好,耐冲击电流强,安全可靠等,是传统压电式传感器无可比拟的。 Its advantage is that a wide measuring range, good linearity, current impact strength, safety and reliability, the conventional piezoelectric sensor is unparalleled. 因为原检测仪在雷击大电流冲击时,是靠氧化锌瞬变抑制组件的保护获取雷击计数值。 Because the original lightning detector when a large current shock is suppressed by transient zinc oxide lightning protection assembly of obtaining a count value. 但,当雷击产生时,对瞬变保护组件造成较大的冲击,容易造成传感器的损坏。 However, when the lightning strikes, resulting in a greater impact on the transient protection components, likely to cause damage to the sensor. 而AMB-05传感器的安装方式是一次侧与避雷器接地端直接连接到地,二次侧与一次侧在耦合环节增加了保护电路然后于采样电路连接,不会直接承受大的电流冲击,安全可靠得多。 AMB-05 and installation of the sensor is connected to the primary side of the arrester ground terminal directly to the ground, the secondary side and the primary side coupling part and increased protection circuit connected to the sampling circuit, a large current is not subjected to direct impact, safety and reliability much more. 另外该传感器同时可感受5~100us信号宽度的雷击信号,具有雷击计数器的功能。 Further the sensor signal simultaneously lightning perceptible signal width of 5 ~ 100us, has a function of lightning counter.

图3是本地监测单元中的无线数据传输终端的结构。 FIG 3 is a wireless data transmission terminal in a local monitoring unit. 如图3所示。 As shown in Figure 3. 无线数据传输终端包括:数据处理单元,无线传输单元和太阳能供电系统三部分。 Wireless data transmission terminal comprising: a three-part data processing unit, a wireless transmitting unit and a solar power supply system.

其中,数据处理单元包含与传感器相连接的相互串联的隔离驱动电路1021、A/D转换模块1023和中央处理器CPU 1025;无线传输单元包含GSM无线收发模块1022和连接口1024,在本实施例中连接口1024为RS485/232接口;它负责将有效信息发送出去,将指令信息消化处理后执行、操作等。 Wherein the data processing unit comprising a series-connected isolation drive circuit 1021 is connected with the sensor, A / D conversion module 1023, and a central processing unit CPU 1025; GSM wireless transmitting unit comprises a wireless transceiver module 1022 and a connection port 1024, the present embodiment 1024 connection port RS485 / 232 interface; a valid which is responsible for sending out information, instruction information to perform post-digestion process operation. 为保证供电系统工作正常,无线数据传输终端还根据外部工作环境的要求,配置了包含太阳能电池1028、太阳能充电控制器1027和机内蓄电池组1026的太阳能供电系统。 To ensure the supply system is normal, the wireless terminal further data transmission according to the requirements of the external environment, the configuration 1028, the solar power system comprises a solar charge controller solar cells and batteries 1027 1026 machine.

如图3结构,由现场传感器输入的信号,经隔离驱动电路1021(保护电路——光电隔离)去除干扰信号送至A/D转换模块1023;A/D转换模块1023将模拟信号转换成数字信号,送至中央处理器CPU1025内;中央处理器CPU1025对数据信号转换成数字信号,送至中央处理器CPU1025内;中央处理器CPU1025对数据进行处理,即组成信息报文,然后送至无线传输单元;信息报文经RS-232/RS-485接口和GSM无线收发(GSM-MODEM)模块,按着GSM无线通讯网络的通讯协议要求以短信息的方式发出此报文信息。 Structure shown in Figure 3, the sensor signal input from the scene, the driver circuit isolation 1021 (protection circuit - optical isolation) removing the interference signal to the A / D converter module 1023; A / D conversion module 1023 converts the analog signal into a digital signal sent to the central processor, the CPU 1025; the CPU 1025 of the central processor data signal into a digital signal, supplied to the central processor, the CPU 1025; the CPU 1025 to a central processing unit for processing data, i.e., the composition information packet, and then sent to the wireless transmission unit ; information packets through the RS-232 / RS-485 interface and the GSM radio transceiver (GSM-MODEM) module, according to the GSM wireless communication network communications protocol is sent the packet of information in an SMS. 本实施例中采取专利号ZL200420019939.4所提供的无线数据传输终端,它主要完本地监测单元与移动通短信中心(GSM)网络的无线连接、处理短信收发等功能。 Wireless embodiment of the present embodiment taken in wireless data transmission terminal provided by Patent No. ZL200420019939.4, which is mainly locally finished monitoring the mobile communication unit message center (GSM) network and connection handling functions such as messaging. 这种利用公网实现数据通信的方式,既解决了远距离数据通讯的关键问题,又降低了系统造价和投资,是一种应用前景无限的自动化通讯手段,应该积极推广应用。 This way of using the public network for data communication, which addresses the key issues of long-distance data communications, but also reduces system cost and investment, is a prospect of unlimited automated means of communication, should actively promote the use.

所述的中央处理器CPU1025是选用抗干扰能力强、低功耗工业级芯片。 The central processing unit is selected CPU1025 interference ability, low-power chip industry. 主要完成内部监控、数据处理、故障数据存储和内部作业调度等功能,该中央处理器CPU1025内还带有故障自恢复功能,大大提高了数据采集终端的抗干扰能力和可靠性。 The main complete internal control, data processing, data storage, and an internal fault job scheduling functions within the central processing unit further CPU1025 with fault recovery function, greatly improves noise immunity and reliability of data acquisition terminal. 无线数据传输终端内有内部时钟和校时功能,数据信息传递时都带有时间标志,这些,可弥补短信数据通讯过程中的数据延迟等问题。 Wireless data transmission terminal has an internal clock and time correction function, are time-stamped data information transfer, these data may make up the SMS data during communication delay problems.

如上述,无线数据传输终端配置的供电系统是太阳能电池系统。 As described above, the power supply system, wireless data transmission terminal system configuration is a solar cell. 这是由于野外很多场合下无供电条件,无线数据传输终端在工作时又不能停电。 This is because under field conditions unpowered many cases, wireless data transmission terminal is not working time and power. 因此,采用太阳能和蓄电池组提供补充能源,确保了无线数据传输终端的连续、不间断地工作。 Thus, the use of solar energy and provide additional battery pack, to ensure continuous, uninterrupted operation of the wireless data transmission terminal.

无线数据传输终端安置于被监测的避雷器本地监测单元内,对设备生产运行过程中的数据进行采集和检测;如果没有该无线数据传输终端,则必须将控制线路敷设到采集点,这样既扩大了系统投资,又不利于生产管理。 Wireless data transmission terminal disposed within the arrester local monitoring unit is monitored, the data process plant production run acquisition and detection; without the wireless data transmission terminal, you must lay the control line to the collection point, so that both expanded system investment, not conducive to production management. 被监测的设备安装无线数据传输终端可快速通过移动通信中心(GSM)网络将产生的数据信息报文发出,报文信息可经主机监控系统完成接收和处理,实现对运行设备的监测和管理。 It monitored devices installed wireless data transmission terminal can quickly through the data information of the mobile communication center (GSM) network the generated packets to be sent, the message information may be accomplished received and processed by the host monitoring system, to monitor and manage the operation of the device.

图4是置于计算机5内的主机监控系统6。 FIG 4 is disposed within the host computer monitoring system 6 5. 如图4所示,置于计算机5内的主机监控系统6包含:接收从移动通信中心(GSM)内的托管服务器传送信息报文的信息接收模块602,与信息接收模块602相连接的处理报文信息和发送指令的信息处理模块603,分别与信息处理模块603相连接的数据库601、配置和调试模块604以及显示报警模块605。 As shown in FIG 4, 5 placed in the host computer monitoring system 6 comprising: receiving transmission information receiving information packets from a server hosted in the mobile communication center (the GSM) 602, the information receiving module 602 is connected to packet handling message information, and information processing module 603 sends instructions, and database 601 are connected to the information processing module 603, configuration module 604 and a debug module 605 and a display alarm.

所述的配置和调试模块604是专门为日常运行、维护、系统调试而配置的,与它相连的信息处理模块603可以通过它向本地监测单元发出索取各种信息的指令;因为,主机监控系统提供给变电站或电厂等场地使用,而每一个使用的对象设备编号、性能、技术参数均不一样,一次结线方式也不一样,设备的安全等级和报警定值也不相同。 The configuration and debug module 604 is designed for daily operation, maintenance, debugging the system configuration, the information processing block 603 connected to it can issue instructions to obtain various information by which the local monitoring unit; for the host monitoring system supplied to the substation or power plant use of venues, and each object using a device number, performance, technical parameters are not the same, the first end-line are not the same, the security level and alarm device is not the same value. 故需要给用户一个自己能够方便运行维护和调试的工具;如设置终端设备的内部时钟、报警次数、电流的门限值等;还有无线数据传输终端现场安装完成后,需要立刻与主机监控系统的操作界面来进行“对话”,就必须使用该模块来完成开通和投运。 Therefore, a user needs to be able to facilitate operation and maintenance and debugging tools; terminal device as set internal clock, alarm times, the threshold current, and the like; and the wireless data transmission terminal installation site, and the host monitoring system needs to immediately the interface to a "dialogue", you must use the module to complete the opening and put into operation.
