Problems solved by technology

[0002] The meter box is a serious fire safety hazard due to many wiring and complicated wiring
Most of the existing fire-fighting methods are to place portable fire extinguishers near the meter box, or use distributed spraying to extinguish the fire in the warehouse area. The spare sand, 1211, dry powder, etc. in the substation are also relatively passive and primitive, and the fire-fighting robot dedicated to fire-fighting is bulky. Cannot be flexibly applied to relatively closed spaces such as indoors and cabinets
[0003] None of the above-mentioned fire-fighting methods can prevent the expansion of the fire, and it is impossible to deal with it in time when the meter box is about to cause a fire

Embodiment 1

[0042] Such as figure 1 As shown, this embodiment provides a fire extinguishing device for the meter box, the device includes:

[0043] The sensor unit, the fire-fighting agent injection system, the processor, the smoke exhaustion system and the audible and visual alarm, the sensor unit, the fire-fighting agent injection system, the smoke exhaustion system and the audible and visual alarm are all electrically connected to the processor;

[0044] The sensor unit includes a smoke sensor, an infrared temperature measurement sensor group and a flame sensor. The infrared temperature measurement sensor group includes four infrared temperature measurement sensors, and the four infrared temperature measurement sensors are respectively installed at the midpoints of the four vertical edges of the meter box; the smoke sensor installation On the top of the meter box, because the smoke floats upwards, it can be installed on the top to quickly sense the smoke.

[0045] The fire-fighting ag...

Embodiment 2

[0048] Such as figure 2 As shown, this embodiment provides a control method for a fire extinguishing device used in an electric meter box, including the following steps:

[0049] S1. Confirm that there is a fire hazard according to the environmental parameters sent by the sensor unit.

[0050]If the signal sent by the smoke sensor or the flame sensor is received, it is determined that there is a fire hazard, and if the actual temperature collected by the temperature sensor exceeds the preset temperature threshold, it is determined that there is a fire hazard.

[0051] After determining that there is a fire hazard, start the sound and light alarm, control the flashing of the warning light and start the buzzer.

[0052] The processor locally stores the administrator information of the meter box as well as the label and location information of the meter box. After confirming that there is a fire hazard, the processor retrieves the locally stored administrator information, and s...

Abstract

The invention provides a fire extinguishing device for an electric meter box and a control method of the fire extinguishing device. The device comprises a sensor unit, a fire-fighting agent injectionsystem, a processor, an inergen system and an audible and visual alarm, wherein the sensor unit, the fire-fighting agent injection system, the inergen system and the audible and visual alarm are electrically connected with the processor; the sensor unit comprises a smoke sensor, an infrared temperature measuring sensor group and a flame sensor, the infrared temperature measuring sensor group comprises a plurality of infrared temperature measuring sensors, and the infrared temperature measuring sensors are respectively arranged at the middle points of four vertical edges of the electric meter box; and the smoke sensor is arranged at the top in the electric meter box. According to the fire extinguishing device, the fire hidden danger of the electric meter box can be found in time, the hiddendanger can be eliminated in time to avoid fire expansion, meanwhile, a fire-fighting agent can be rapidly cleaned to provide a good repair and inspection environment for repair and inspection personnel, and circuit repair and inspection can be conveniently and rapidly carried out.

Description

technical field [0001] The invention belongs to the technical field of electric equipment fire protection, and in particular relates to a fire extinguishing device for an electric meter box and a control method thereof. Background technique [0002] The meter box is a serious fire safety hazard due to the large number of wiring and complicated wiring. Most of the existing fire-fighting methods are to place portable fire extinguishers near the meter box, or use distributed spraying to extinguish the fire in the warehouse area. The spare sand, 1211, dry powder, etc. in the substation are also relatively passive and primitive, and the fire-fighting robot dedicated to fire-fighting is bulky. It cannot be flexibly applied to relatively closed spaces such as indoors and cabinets. [0003] Above-mentioned fire-fighting method all can't realize the prevention to fire expansion, can't handle it in time when electric meter box will cause fire. Contents of the invention [0004] Ai...
