Description

An electrical fire monitoring equipment box

technical field

The utility model relates to the technical field of electrical fire monitoring, in particular to an electrical fire monitoring equipment box.

Background technique

At present, with the surge of electrical equipment and electricity consumption, the proportion of electrical fires caused by this is getting higher and higher in all kinds of fires, and the losses caused are becoming more and more serious. The most effective way to prevent electrical fires is to install Electrical fire monitoring system. On the one hand, the traditional electrical fire monitoring system is characterized in that the leakage monitoring is an early pre-alarm, and the data is reported to the server computer in the monitoring duty room through the communication line. If the communication is disconnected, the working status and fault alarm cannot be reported in real time. It cannot work normally after interruption of normal power supply. It cannot be guaranteed that the electrical fire monitoring equipment will always be in an effective working state after a fire occurs, and it cannot play its role in the event of a fire, and cannot centrally monitor all detectors to upload data, so as to achieve the ultimate goal of protecting lives and reducing property losses. On the other hand, the traditional electrical fire monitoring equipment is installed in a vertical cabinet. The installation box is large in size and poor in heat dissipation, which brings inconvenience to construction and is not conducive to maintenance and removal.

Contents of the invention

In order to solve the problems in the prior art, the purpose of this utility model is to provide an electrical fire monitoring equipment box, which has a wall-mounted electrical fire monitoring equipment box with a backup battery, which can be visually monitored when electrical leakage or fire occurs. It can display on-site leakage and temperature conditions, and can alarm and store data in time. It is small in size and convenient for installation and debugging.

The technical scheme adopted in the utility model is:

An electrical fire monitoring equipment box, comprising a square main box body and a box door axially connected to the main box body; shark gill cooling vents are provided on the side wall of the main box body; a touch display screen is provided on the box door , the lower part of the touch screen is provided with a warning lamp and a button, and the left side of the touch screen is provided with a buzzer; the upper middle part of the door is provided with a cabinet lock; the bottom of the main box is provided with a battery; the main box The body is connected with multiple temperature detectors and multiple residual current detectors through the second communication bus.

The beneficial effects of the utility model are:

1. This new type can provide backup power to the power supply of the electrical fire monitoring system when the main power supply fails, so that it can normally monitor the leakage current and indoor temperature, and can immediately send out an alarm indication sound when the alarm value is reached, reducing the loss and damage caused by the fire. Protect life.

2. The new box body is easy to install, and can be fixed anywhere in the wall-mounted installation. The installation volume is small, and the heat dissipation is good, which is convenient for maintenance and maintenance. The communication adopts the two-bus method to combine the power supply line and the signal line into one, which saves construction and cable costs, and brings great convenience to on-site construction and later maintenance. On the one hand, it saves the cost of fire-fighting equipment and saves power energy.

3. The new type has high working stability and reliability, and good expansion performance. When a leakage occurs, the non-independent intelligent residual current transformer quickly collects data, and uploads it to the electrical fire monitoring system device to display and record the location and time of the fault. , and send out sound and light alarm signals, thus effectively ensuring timely alarm when a fire occurs.

Detailed ways

Below in conjunction with accompanying drawing and reference numeral the utility model is described in further detail.

As shown in Figures 1-4, an electrical fire monitoring equipment box includes a square main box body 1 and a box door 9 axially connected to the main box body;

Shark gill cooling vents 10 are provided on the side wall of the main box 1;

Described chamber door 9 is provided with touch display screen 4, is provided with alarm light 5 and button 6 in touch display screen 4 bottom, is provided with buzzer 7 in touch display screen 4 left side; With cabinet lock 8;

A storage battery 13 is provided at the inner bottom of the main box 1;

The main box 1 is connected with a plurality of temperature detectors 2 and a plurality of residual current detectors 3 through two communication buses. And be connected to terminal block 14 on main box body 1.

The lower part of the inner backboard of the main box 1 is clamped with an air switch 17 through the terminal row 14, and is also fixedly connected with an alarm 12 through a card slot; wherein the air switch can be purchased in the market, Siemens standard 2P vacuum circuit breaker , the model is 5SJ65637CR.

A power controller 15 and a power monitor 11 are fixed in the middle of the inner backboard of the main box 1; the power controller 15 can be purchased in the market, and the Delixi standard 24v100W switching power supply is modeled as SA10024; the power monitor 11 can be purchased in the market, the model is NZ7-630 power monitoring and mutual conversion of Chint Electric Appliances manufacturer.
