Abstract
The utility model relates to an electrical fire monitoring detection system. The electrical fire monitoring detection system is characterized in that the electrical fire monitoring detection system is composed of a monitoring detector and a monitoring device, wherein the monitoring detector is composed of a current transformer, a temperature sensor, an amplifier, a digital-to-analog conversion module, a calculator and a detection stage; and the monitoring device is composed of an amplifier stage, a calculator, an alarm, a displayer, a control signal output stage and a storage/printing system. The amplifier in the monitoring detector receives and analyzes current signals transmitted by the current transformer and sends information to the calculator; and the monitoring device displays and processes the information transmitted from the monitoring detector and gives an alarm on the site in real time. An electronic address encoding method is adopted fully by the electrical fire monitoring detection system, the novel technical scheme enables electrical fire monitoring detection system to be installed simply and conveniently, alarm treatment can be performed at first time when danger occurs, and accordingly fires are reduced.
Description
Technical field
The utility model belongs to the fire hazard monitoring technical field, especially a kind of electric fire disaster monitoring detection system.
Background technology
[0002] As time goes on, China's per capita household electricity consumption has turned over some, but also sharp increase thereupon of electrical fire has caused massive losses for national economy and people's lives and properties.According to relevant department to the electrical fire analysis of statistical data; The electrical fire major part is that reasons such as phase fault, leakage current, isolating switch or circuit overload cause; Especially humid environment, impaired, the line mutual-ground capacitor of insulation become big, and the fire that the leakage current of generation causes frequently takes place especially.In recent years; The domestic situation that electrical fire is significantly risen is released a series of electric fire disaster monitoring solution; Through detection to supply line's leakage current; The leakage current data, leakage current of monitoring whole architectural power supply circuit intuitively, all sidedly reported to the police, supply line's power failure state novel, thereby find electric aging, moisture-induced electric disaster hidden-trouble early, reduced the risk that fire takes place.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, fully adopts the electronic address coded system, and state-of-the art technical scheme makes its installation easier, can be during dangerous the generation in the very first time processing of reporting to the police, thus reduced the generation of fire.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of electric fire disaster monitoring detection system is made up of monitoring detector and watch-dog; Wherein, monitoring detector by current transformer, temperature sensor, amplifier, D/A switch module, counter, detect the level form; Watch-dog is made up of amplifier stage, counter, alarm, display, control signal output stage, storage/print system; Amplifier during monitoring is surveyed receives and analyzes the current signal that current transformer transmits, and information is sent to counter; Watch-dog shows and handles the information of from monitoring detector, transmitting, carries out real-time onsite alarming.
And described monitoring detector takies 1 address of detection circuit, the monitoring of one road residual current.
And described current transformer adopts totally-enclosed epoxy casting insulation technology.
And, link to each other through lead between described monitoring detector and the said watch-dog.
The advantage and the good effect of the utility model are:
1, current transformer adopts totally-enclosed epoxy casting insulating products; Be applicable to rated frequency 50HZ; Make voltage in the electric system of rated voltage 35KV and following inside plant; The measurement of electric energy and used for relay protection are when mutual inductor during excitation, can bear the 1S external short circuit and not damaged under rated voltage.
2, adopt not merely vertical detector to survey residual current; And when this residual current reaches setting value, send the acoustic alarm and the visual alarm of certain intensity, and keep, until hand-reset; Have working station indicator and self-checking function, can also be practical separately.
3, has automatic inspection function; The state that did not stop in 24 hours to all controlled points in the system carries out itinerant monitor system; The address and the information of rapid warning and the controlled point of display abnormality when unusual; Prompting operator on duty or professional and technical personnel's policing system are fixed a breakdown, and make total system recover operate as normal.
Description of drawings
Fig. 1 is that the system of the utility model connects block diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is done further detailed description:
As shown in Figure 1, the described a kind of electric fire disaster monitoring detection system of the utility model is made up of monitoring detector and watch-dog; Wherein, monitoring detector by current transformer, temperature sensor, amplifier, D/A switch module, counter, detect the level form; Watch-dog is made up of amplifier stage, counter, alarm, display, control signal output stage, storage/print system; Amplifier during monitoring is surveyed receives and analyzes the current signal that current transformer transmits, and information is sent to counter; Watch-dog shows and handles the information of from monitoring detector, transmitting, carries out real-time onsite alarming.
The structure and the principle of work of the utility model are as shown in Figure 1; For reaching the purpose of the utility model; Current sensor and temperature sensor are set in monitoring detector,, amplify the information via D/A switch module that collects and in counter, calculate accurately through the amplifier amplifying signal.When electrical equipment electric leakage in a single day and overrate, alarm sends visual alarm immediately and passes through the size of display demonstration leakage current, and stores/print.
It is emphasized that; The described embodiment of the utility model is illustrative; Rather than it is determinate; Therefore the utility model is not limited to the embodiment described in the embodiment, every by those skilled in the art according to other embodiments that the technical scheme of the utility model draws, belong to the scope of the utility model protection equally.
