Cable trench cable fire alarming and self-extinguishing apparatus

Abstract

The invention provides a cable trench cable fire alarming and self-extinguishing apparatus. The cable trench cable fire alarming and self-extinguishing apparatus comprises four parts, i.e. a flame detector for acquiring an ultraviolet signal of flame nearby a cable end, a fire extinguisher unit capable of spraying ultrafine dry powder, a single chip microprocessor unit for operating and processinga signal of the sensor and controlling the triggering of the fire extinguisher, and a power supply unit. A main function of the cable trench cable fire alarming and self-extinguishing apparatus is tomonitor the ultraviolet signal nearby the cable trench cable end in real time, to determine whether the fire occurs, to transmit a positioning and alarming signal to a remote device such as a mobilephone, a computer and the like and to automatically trigger the action of the fire extinguisher, thereby achieving a purpose for rapidly and timely controlling the fire.

Description

technical field [0001] The invention relates to the fields of power electronics, high voltage and insulation, single-chip microcomputer technology, signal processing and analysis, in particular to a cable fire alarm and automatic fire extinguishing device for cable trenches. Background technique [0002] With the continuous and rapid growth of my country's economy, the demand for domestic electricity and business electricity is increasing. As one of the main ways to transmit electric energy, the reliability of power cables is of great significance. At present, under the influence of various factors such as cable design, production, installation and maintenance, and operating environment, power outage accidents caused by cable damage are in a state of high incidence, which is one of the important hidden dangers for the safe operation of the power grid. [0003] The monitoring of the cables in the cable trench during operation is through the daily inspection of the on-duty st...

AI Technical Summary

Problems solved by technology

At present, under the influence of various factors such as cable design, production, installation and maintenance, and operating environment, power outages caused by cable damage are in a high-incidence state, which is one of the important hidden dangers for the safe operation of the power grid.

[0003] The monitoring of the cables in the cable trench during operation is through the daily inspection of the on-duty staff. The method is single and cannot be directly observed. It is difficult to find out the hidden dangers of fire or unsafety during the operation of the cables in time.

A fire in a cable trench is highly concealed, has a wide range of influence, and takes a long time to repair and recover. Once it occurs, it may cause serious consequences

In addition to causing cable damage, cable fires may also cause serious consequences such as equipment tripping, supply load reduction, and even injury to firefighters.

Not only will it bring serious losses to the economy, but it will also disrupt the normal life and production order of residents and enterprises.
