Abstract
The utility model relates to a switch cabinet temperature monitoring system based on the wireless network. The switch cabinet temperature monitoring system comprises a wireless temperature sensor unit, a temperature monitoring unit and an upper computer, wherein the wireless temperature sensor unit and the temperature monitoring unit are in wireless communication, and the temperature monitoring unit is connected with the upper computer via a networking communication interface circuit. A wireless temperature sensor adopted by the system has a small size and can be pasted on a heating point. The switch cabinet temperature monitoring system is low in energy consumption and is powered by batteries, thereby avoiding power problems that are caused under passive conditions. In addition, the system is capable of timely and accurately reflecting the change in the temperature increase of a measuring point. When the temperature exceeds a temperature limit, warning signals are emitted by an indicating lamp and a relay of an in-situ display terminal and or by a remote management platform, thereby preventing accidents caused by overheated equipments.
Description
Technical field
The utility model relates to the correlative technology field of switch cubicle monitoring, is specifically related to a kind of switch cubicle temperature monitoring system based on wireless network.
Background technology
Nowadays oneself uses the switch cubicle of high load capacity in a large number in electrical network.And the over-heat inside phenomenon of switch cubicle has become the FAQs of switch cubicle in using, because the leakproofness of switch cabinet, in the heavier area of some loads, has the temperature rise of the switch cubicle problem that exceeds standard.The temperature rise of switch cubicle exceeds standard, and directly influences the safe and stable operation of equipment, and problems of excessive heat is a constantly process of development, if do not control, degree of superheat is aggravation constantly, and to the performance of insulating part and produce very big influence equipment life.Because heat generating spot is in sealed cabinet, operating cabinet gate inhibition only opens, and the operator on duty can't find the heating defective through normal supervision means.Generating heat, joint can redden even fuse when serious, directly causes industrial accident.According to statistics, electric system has an accident has considerable part relevant with problems of excessive heat in the reason, and contact, the connector temperature of therefore adopt an effective measure monitoring high-voltage switch gear, high voltage bus and high-tension cable are the problems that electric system need solve.In order to monitor the heating situation of inner each parts of switch cubicle in real time, assurance equipment normally moves, and reduces accident rate, is badly in need of switch cubicle is transformed, and installs temperature measuring equipment additional.
