Henan switchgear wireless temperature measurement

1 basic content in industrial systems, the temperature is an important parameter to characterize the device operating normally. With the continuous growth of industrial electricity load, in order to avoid emergencies due to equipment caused by heating, automatic temperature monitoring has become an important part of industrial production safety. Some defective operation of the electrical equipment typically operates at high voltage and high current state, present in the device can lead to abnormal temperature rise of the device components. Resulting in a vicious cycle of temperature and contact resistance value will eventually cause the device does not work, even burning, high temperature may cause a fire, explosion or damage to equipment or quality of the accident. High-voltage electrical equipment, due to limited fault testing methods, especially temperature gauge points less likely to be found in the switch box and enclosed bus. With the extension of the temperature rise time, the temperature gauge Office will increase due to heat and oxidation, which may result in a serious accident destroyed the bus, the contact, the contact plate destroyed, power failure and the like. Wireless temperature measurement system with real-time online monitoring, poor working conditions, easy installation, timely warning and other characteristics, can effectively ensure the safety of high-voltage electrical equipment. 22 wireless temperature measuring system system components physical map (6) Wireless Temperature Measurement System communication terminal (receiving instrument temperature), temperature monitoring and early warning station consists of wireless temperature sensor, [1] in three parts. Wireless temperature sensor (TST-S100): measuring the temperature of the contact point. Mainly installed in easy to heat the place. Each wireless temperature sensor has a unique ID number, installation location for each sensor records the actual installation, and the number is stored together with the temperature monitoring workstation computer database. Sensor at regular intervals (you can pre-set) automatic transmit temperature data of a monitoring point, but if the temperature abnormal alarm immediately, without limiting the transmission cycle. Wireless Temperature receiving instrument (TST-R100): installed in the substation, installed according to the installation area, is responsible for receiving the respective wireless temperature sensor (probe) to measure and send the temperature data, and connected through a bus to upload temperature data to the management computer response management software commands. Workstation System (TST-W100): wireless temperature client software, real-time display of the monitoring area monitoring temperature data points and curve, and query and analysis, if it is found overheating or sharp temperature was raised to set the alarm to the police. 33 centralized wireless measurement system has been put into use for the substation, power distribution room to add wireless temperature measurement system, conventional solutions have openings in the switch cabinet, install the receiving device, a lot of manpower and material resources, the blackout time It is relatively long, and the need for construction professionals, very inconvenient. The new centralized wireless measurement system has been put into use mainly for substation, power distribution room, adding a special case of a wireless temperature measurement system transformation presented new solution is particularly suitable for the transformation of the existing stations and outdoor temperature measuring devices, also apply to the new station . 1, a small amount of program engineering and switchgear Free opening, wiring, saving time and cost transformation. 2, in the transformer room, distribution room centralized display can be connected through a variety of means of communication with the master station, such as RS-485, fiber optic, Ethernet communications network. 3, powerful, a centralized display device may be configured to receive up to 299 wireless temperature sensor, display and intuitive, with database management, historical curve inquiry functions. 7-inch color LCD screen, a more clear and intuitive. 4, with SMS alarm function can be set in advance in the central display of alarm telephone numbers in the device, when monitoring anomalies, promptly notify the staff to send text messages. Specific equipment consists of: 1, the wireless temperature sensor: WXC3000S-W2-433M, centralized display device equipped with a centralized transmitter, 433M, high power. 2, centralized receiving display device: WXC3000C, Wall installation, 800 * 480 color LCD, a variety of transmission options, with up to 299 sensors. 3, temperature measurement system master: WXC3000MS, hardware: DELL servers, RAID disk groups, 1920 * 1080 LCD display, 3G wireless router. 4, software: Windows2003 operating system, CS temperature master system software architecture. [2] 44 works to control the device under test by the temperature sensor into a digital signal by the single-chip microprocessor wireless temperature sensor, and then transmitted to the reader through the wireless transmitting and receiving module, will be collected by the microprocessor temperature information, uploaded to a PC computer via 485 communication module. [3] The plurality of sensors distributed around the electronic tag reader in the effective communication range can be added, deleted, moved, temperature measurement terminals. The reader is installed in the control center, the control center computer software real-time monitoring at each point temperature, temperature monitoring computer operating temperature data collected from each monitoring point temperature communication terminals, for long-term storage in the database, real-time display monitoring points The temperature curve and analyzed, once discovered overheating or sharp temperature was raised to set the alarm to the police, to achieve heat homes grasp the situation of the whole system
