Abstract
The utility model relates to a high-voltage cabinet contact high-temperature sensor node apparatus with an alarm device. The apparatus comprises a circuit board; a JN5139 wireless chip, a high-voltage cabinet contact high-molecular temperature indicating sheet, a carbon dioxide sensor, a reset circuit and a clock circuit are arranged on the circuit board; the JN5139 wireless chip is connected with the high-voltage cabinet contact high-molecular temperature indicating sheet, the carbon dioxide sensor, the reset circuit and the clock circuit in a signal manner; and the circuit board is also provided with the alarm device. By using the apparatus provided by the utility model, super-high temperature alarm can be realized, and at the same time, by means of the clock circuit and a software positioning algorithm, problems of a conventional high-temperature contact are solved that the sensitivity of temperature parameter monitoring is low and the time recording and position locating are difficult so that vast internal information is provided for fault diagnosis and early warning of a prefabricated transformer substation, and the sensor node apparatus cooperates with the router, the coordinator and the like of a wireless sensor network so as to carry out the monitoring alarm function.
Description
Technical field
The utility model relates to a kind of pyrostat of high voltage cabinet contact with warning device node apparatus.
Background technology
The trolley type switch cabinet generally used at present, owing between isolating switch and switch cubicle, adopting plug to connect, dolly and switch cubicle because manufacturing, transportation, install badly, and the reasons such as percussion in using all will cause poor contact of contacts, the contact temperature rising occur; Contact temperature is too high, and its contact resistance value will be increased, and temperature further rises.When temperature rises to the conductor contact point fusing, will cause electrical equipment and system to open circuit or ground short circuit, cause the generation of serious accident, the serious threat electric power netting safe running.From the long-term safety service requirement, consider, the maximum heating temp of high-tension switch cabinet contact must not surpass the maximum heating temp that allows.Therefore adopt a kind of applicable temperature monitoring method, it is very necessary that the temperature of high-tension switch cabinet contact is carried out to on-line real time monitoring.The supervisory system or the performance that on market, exist now are not high, or function is simple, or performance is higher but expensive.
