Fire extinguishing plug for cable trench internal fire early warning and automatic alarm

Abstract

The invention provides a fire extinguishing plug for cable trench internal fire early warning and automatic alarm. The fire extinguishing plug is characterized by comprising a data display and acquisition module, an alarm module, a sensor group, an aerosol fire extinguishing module, a communication module and a fire extinguishing plug body. The extinguishing plug body provided by the invention hasthe functions of rain prevention, dust prevention and lightning protection. The upper part of the fire extinguishing plug body are provided with display and alarm devices, and a side face of the fireextinguishing plug is provided with a maintenance door to facilitate the maintenance and repair of the fire extinguishing plug. The front side of the fire extinguishing plug is provided with a switchbutton for controlling the display parameters of the display device to be switched between gas concentration and temperature, a seam of the maintenance door is subjected to special processing so as to ensure the waterproof and dustproof performance of the seam. With the consideration of high temperature in summer and low temperature in winter, different alarm and fire extinguishing data combinations are set for the temperature and mixed gas concentration, and false alarm and missed alarm are effectively avoided. Through setting the system power supply, the high reliability and high stabilityof a power supply system of the fire extinguishing plug are ensured.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing control, in particular to a control device for fire early warning and automatic alarm in a cable trench. Background technique [0002] In the construction of substations, it is inevitable that the low-voltage power cables, control cables, communication cables and relay protection and optical cables used in the automation system of the power system will be laid in the same ditch. A certain amount of heat will be generated during the operation of power cables, plus various other reasons, if one of the cables catches fire, it will quickly spread. Cable fire can not only burn the cable itself, but also burn the control cable and optical cable together, causing power grid accidents. Therefore, whether the comprehensive fire protection measures of the cable trench are reliable is of great significance to the safe operation of the power grid. [0003] The current fire protection measures for...

AI Technical Summary

Problems solved by technology

[0003] The current fire protection measures for cable trenches in substations are relatively simple, and fire-resistant walls are still the most important means; in addition, there are some real-time monitoring for cable trenches, but they are mainly focused on temperature monitoring, and there is no local display or the local display
