Fire-resistant bus duct online monitoring method

Abstract

The invention discloses a fire-resistant bus duct on-line monitoring method. The method comprises the following steps:1, arranging a temperature sensing element in each fire-resistant bus duct, wherein the temperature sensing element comprises an infrared thermal sensing probe and a signal conditioning circuit; 2, arranging a temperature acquisition and emission element in each fire-resistant busduct, wherein the temperature acquisition and emission element comprises an environment sensing element, a single-chip microcomputer and a wireless transceiver; obtaining a node temperature rise valueof a monitoring node where the single-chip microcomputer is located; 3, through the temperature acquisition and emission element, sending the node temperature rise value to a monitoring management center through a ZigBee communication protocol, wherein the monitoring management center distributes the node temperature rise value to each user terminal in the form of a text and a curve; and 4, setting an early warning threshold value on the user terminal, and giving an alarm when the received final temperature rise value exceeds the set early warning threshold value. According to the invention,online monitoring of the fire-resistant bus ducts can be realized, and major accidents of a power supply system caused when the temperature rise exceeds a limit value are avoided.

Description

technical field [0001] The invention specifically relates to an on-line monitoring method for a fire-resistant bus duct. Background technique [0002] Busway was introduced into my country in the 1950s. Because of its large current carrying capacity and strong applicability, it has become an important branch of the power transmission and distribution industry after several generations of development and is widely used in various industries. The function of the busway is to collect, distribute and transmit electric energy. It has the characteristics of large carrying capacity, strong and safe, easy to install, easy to disassemble, easy to maintain, and strong environmental adaptability. Busway has incomparable advantages compared to cables in places such as high current and industrial and mining. With the rapid improvement of building automation and industrial automation, users often ignore the safety management of busway, such as overload, accelerated insulation aging and l...

AI Technical Summary

Problems solved by technology

[0004] One is to conduct regular inspections manually with an infrared thermometer, which leads to imperfect data collection and heavy workload; in addition, it cannot effectively prevent electrical disasters in bus ducts

[0005] The other is to paste a heat-sensitive temperature patch on the outside of the busway connector. The patch changes from white to colored after reaching a certain temperature. The inspection personnel can directly observe it, but the patch is not reversible. It needs to be replaced, and the bus duct is installed at high altitude or in the basement, sometimes it is difficult to observe

[0006] From the above two methods, it can be seen that in the prior art, the temperature information of the busway cannot be monitored in real time, and when the temperature is close to or exceeds the threshold, the alarm cannot be timely
