【摘要】 随着我国社会经济的快速发展,电力供应供不应求,大部分省市已经出现拉闸限电的现象,与此同时电力用户对供电可靠性、电能质量和服务水平的要求在不断提高,电力用户和供电企业提高自身效益已列为生产经营的目标,在目前电力供应紧张的情况下,迫切需要对配电房中各开关柜内接触头温度变化情况进行在线实时监测,DWJ-2000H(T)系列智能无线温度监测系统可全天候实时有效的监测电力设备、特别是高压电力设备如高压开关柜插接触头、室内(户外)隔离刀闸触头、电缆出线接头、主变引线连接头等在大电流通过时温度的变化情况,系统感温元件紧贴在被测物体的表面,能如实地反映设备的实时温度,实现对电网运行的自动化监控,保障电网运行的安全。DWJ-2000H(T)系列智能无线温度监测系统是应用现代电子技术、通信技术、计算机及网络技术,将高压设备接触头的温度数据实时在线监测,实现电网安全运行。在调研阶段,查阅了国内外相关的研究成果,提出了自主研发和应用的目标要求:首先,在数据传输方面,采用了实时数据无线的传输方式,避免了高压设备与低压设备之间的物理连接。其次,在通信规约方面,通信方式采用232/485总线或CAN网总线组网方式,使产品可以灵活与其它公司的系统兼容。再者,设计过程特别注重电磁兼容性能,以抗干扰作为一条主线,贯穿整个设计过程。抗浪涌、瞬变、高频干扰、工频磁场、高压耐受等等,都做了很好的防范措施。更多还原

【Abstract】 Along with our country social economy’s fast development, the electric power supply falls short of demand, majority of provinces and cities already appeared pull the phenomenon which the floodgate limits power consumption, at the same time the power consumer to the power supply reliability, the electrical energy quality and service level’s request is enhancing unceasingly, the power consumer and the power supply enterprise raises own benefit to list as the production operation the goal, in the present electric power supply intense situation, urgent needs various switch cabinets to inscribe the contact temperature change situation to the switching house to carry on the online real-time monitor, DWJ-2000H(T) series intelligence wireless temperature monitoring system may all-weather real-time effective monitor power equipment, be specially the high pressure power equipment like high pressure switch cabinet peg grafting contact, indoor (outdoors) isolates the knife switch contact, the electric cable going beyond a line attachment,The host changes the lead wire connection in the big electric current through the time temperature change situation, the system bulb clings prime in was measured that the object the surface, can reflect truthfully equipment’s real-time temperature, realizes to the electrical network movement automated monitoring, safeguards the electrical network movement the security. DWJ-2000H(T) series intelligence wireless temperature monitoring system is the application modern electronic technology, the communication, the computer and the networking, the high pressure unit contact head’s temperature data real-time online monitor, realizes the electrical network safe operation.In the research stage, the author consulted the relevant research results of home and overseas Chinese, put forward independent research and development and application of the objectives and requirementsFirst, in the data transmission aspect, has used the real-time data wireless transmission mode, has avoided between the high pressure unit and the low pressure equipment’s physical connection.Next, in the communication protocol aspect, the mailing address uses 232/485 main line or the CAN net main line network way, enables the product to be possible nimble and other company’s system is compatible.Furthermore, the design process pays great attention the electromagnetic compatibility performance specially, takes a master line by the antijamming, the penetration entire design process. The anti-surge, transient, the high frequency interference, the power frequency magnetic field, the high pressure endure and so on, has made the very good measures.更多还原
