Abstract
The utility model belongs to the technical field of fire alarming cables, and specifically relates to a low-melting broken circuit alarming line. The utility model discloses the low-melting broken circuit alarming line which is characterized by comprising a varnished wire, a low-melting wire, a short-circuit wire, an internal insulating layer and an external insulating layer; the low-melting wire is arranged at the outer side of the varnished wire in a wounding way; one end of the varnished wire is connected with one end of the low-melting wire via the short-circuit wire, and the idle ends of the varnished wire and the low-melting wire are led out as lead wires; the internal insulating layer is located between the varnished wire and the low-melting wire; and the external insulating layer is arranged at the outermost side in a covering way. The utility model aims at improving the structure of a fire alarming line so as to solve the problems of high cost and inconvenience in use of the existing alarming line.
Description
Technical field
The utility model belongs to the fire alarm technical field of cables, is specifically related to a kind of eutectic breaking alarming line.
Background technology
Improving constantly of Along with people's living standard, increasing electrical equipment is applied to each occasion, as: hotel, automobile, storehouse, shop, sub-district, factory or the like.Bring people simultaneously easily at electrical equipment, fire occur in the normal life of affect people's to a great extent, the safety of life and property that threatens people, so fireproofing is particularly important.Common on the market fire prevention system is a lot, still, all is on controller, to do improvement mostly, and the improvement of alarming line aspect is seldom arranged, even if there is the cost of alarming line also very high, uses very inconvenience.
The utility model content
The purpose of the utility model:, have high, the awkward problem of cost that alarming line exists now to solve, and propose a kind of eutectic breaking alarming line in order to improve the structure of fire alarm line.
The technical scheme of the utility model: a kind of eutectic breaking alarming line wherein, comprises enameled wire, low fuse, shorting stub, inner insulating layer and external insulation layer; Described eutectic filament winding is located at the outside of said enameled wire; One end of described enameled wire is connected with an end of low fuse through shorting stub, and the idle end of described enameled wire and low fuse is drawn as lead-in wire; Described inner insulating layer is arranged between enameled wire and the low fuse; Described external insulation layer is coated on outermost.
A kind of eutectic breaking alarming line of the utility model, owing to be provided with enameled wire, low fuse, shorting stub, inner insulating layer and external insulation layer specially, an end of enameled wire is connected with an end of low fuse through shorting stub; And the idle end of enameled wire and low fuse is drawn as lead-in wire, so when fire took place, in a single day low fuse reached its fusing-off temperature and promptly fuse; At this moment, the resistance generation marked change of the lead end of enameled wire and low fuse is when controller detects this variation; Promptly send control signal, thereby realize reporting to the police and outage such structural design; Cost is very low, and very easy to use.
Description of drawings
Fig. 1 is the structural representation of the embodiment of a kind of eutectic breaking alarming of the utility model line;
Structural representation when Fig. 2 is the use of a kind of eutectic breaking alarming of the utility model line.
Embodiment
As shown in Figure 1, the utility model provides a kind of eutectic breaking alarming line, wherein, comprises enameled wire 1, low fuse 2, shorting stub 3, inner insulating layer 4 and external insulation layer 5; Low fuse 2 is set around the outside of enameled wire 1; One end of enameled wire 1 is connected with an end of low fuse 2 through shorting stub 3, and the idle end of enameled wire 1 and low fuse 2 is drawn as lead-in wire; Inner insulating layer 4 is arranged between enameled wire 1 and the low fuse 2; External insulation layer 5 is coated on outermost.
As shown in Figure 2, when this alarming line is applied to fire alarm system, only need the lead end of enameled wire 1 and low fuse 2 is connected to control box 7 through lead 6, can monitor in real time fire monitoring district 10.When fire takes place, because low fuse 2 has very low fusing-off temperature, in case the temperature of scene of fire reaches this fusing-off temperature; Low fuse 2 fuses very soon, and at this moment, control box 7 detects the resistance generation marked change of the lead end of enameled wire 1 and low fuse 2; Send control signal immediately, control signal is divided into two kinds, and a kind of is alerting signal 8; The information that fire is taken place passes to people or control system, thereby takes appropriate measures early; Another kind is a power-off signal 9, with the dump of corresponding electric appliance, reduces the loss that fire brings.
The structural design of this alarming line is very simple, and cost is very low, and very easy to use.
It is to be noted; This alarming line can be used in any one zone that needs fire monitoring; Can adopt single line segmented mode and multi-line section mode; Promptly one section alarming line is connected with control box 7 and multistage alarming line and control box 7 ways of connecting, thereby realizes the real-time monitoring of the condition of a fire and the timely processing of fire.
In addition, the fusing-off temperature of low fuse 2 can be provided with as required, as adopts 100 ℃ to 200 ℃ low temperature fuse.
Above-described only is the preferred implementation of the utility model; Should be understood that for a person skilled in the art; Under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not influence effect and practical applicability that the utility model is implemented.
