High Voltage Switchgear electric power plants, substations, high-voltage electrical equipment in many power transmission connection point is the weakest link in the long-running process equipment substantive issues in this weak link is the connection point fever. As the load increases, resulting in junction fever and a vicious cycle: temperature, expansion, contraction, oxidation, resistance increases, heating up again. These temperature of the heating unit is not real-time monitoring, which ultimately lead to fires. By monitoring the switchgear temperature operation of an electric shock, which can effectively prevent the switching cabinet of the fire, but because of the high voltage switchgear narrow structure, can not be artificially inspections temperature, thus achieving Temperature monitoring is to ensure the safe operation of high voltage switchgear important tool. The front-end wireless digital temperature sensors, temperature sensors can be installed quickly and easily on the measured voltage live body contacts, accurately track temperature heat junction; wireless temperature sensor uses RF technology transfer temperature information to achieve the collection and isoelectric point is collected, safe and reliable. Cabinets end of this product can accurately report the operation of high voltage test equipment for all components easy to heat rise, to provide reliable data basis for the safe operation of equipment; temperature monitoring function to run the software installed in the city, district monitoring center of the powerful, the system database through The geographical distribution of man-machine interface, junction temperature operating parameters, pre-warning information, historical parameters through graphics, tables, curves, bar graphs and other forms of visual display, provide the most direct and reliable data basis for decision-making, to eliminate hidden dangers, the maximum reduction of accidents. Temperature Monitor is equipped with a standard communication interface, running on a network through the host computer, can record switchgear operating temperature data provide the basis for the switchgear maintenance, failure to achieve the switchgear predictive maintenance. The system not only saves a lot of manpower, material resources, and shows the temperature wax, infrared temperature compared also reflects the temperature of the product system with high precision, fast response, small size, easy to install, real-time online, optical fiber transmission, strong anti-interference, etc., is a revolution in the traditional way of temperature measurement.

Each 6-12 channel for users. The device can be promptly temperature information collected by sensors digitize analysis and processing, the system can promptly get all measured points normal, alert, alarm, three unbalanced temperature information. 3) operating-state data display system displays three sections I. cabinet display terminal: Cabinet display module can display real-time online test contacts of the cabinet all normal, alert, alarm and three unbalanced temperature data. Can run automatically, you can manually inspection. . II power plant control room display terminal: power plant control room display module can display real-time online test of the power station switchgear tested all normal contacts, warning, alarm and three unbalanced temperature data. Can run automatically, you can manually inspection. III regional control centers to run the software: The software can be installed on a server regional monitoring center, real-time online display of all power plants in the region accused of any power plant, each measured point to any switchgear normal, alert, alarm, three Unbalanced Operation temperature data. 4) The self-test function to ensure the safety of equipment: all levels of the terminal of the system has automatic fault diagnosis, automatic reporting, automatic recovery feature ensures system reliability. 5) Communication function: cabinet terminal and power plant control room terminal has a data communication interface, system users can request to transfer operational data to address any user needs. Mating dedicated conversion interface, LAN and remote networking communications. 6) storage, printing functions: the control room terminal and system software offers storage, printing module, the system can be measured warnings, alarms, and three unbalanced operating data by time, address storage, data can be printed if necessary a written document. Wireless temperature sensor Wireless temperature sensor by the temperature collection point and the wireless transceiver components. Temperature collection points are so small it can be freely be installed in any point of the test object; temperature data collection point line and wireless transceiver connected to other potential form, the temperature data from the wireless transceiver in the form of real-time reporting of wireless base stations. Transmit temperature information using radio frequency technology to achieve the collector and the collection points and other potential, safe and reliable. Temperature monitoring central station software which runs on the host computer for processing cabinet temperature data collected each station sent a strong database for computing, display pre-warning, store the print. The software needs to be ordered separately. 1. The full account of the development of ideas unmanned stations, server maintenance; 2. The system software is simple, clear interface; 3.
