Description

Copper-clad flat wire with high safety performance

Technical Field

The utility model relates to a copper flat wire technical field specifically is a copper-clad flat wire that security performance is high.

Background

At present, the used winding wire of motor, electrical apparatus product generally adopts the copper flat wire, and current copper flat wire is because under the long-term tensioning operating condition, all easily leads to the copper flat wire fracture or the too big inside copper conductor of load to generate heat seriously, and whether fracture or the serious condition that generates heat all probably cause the conflagration of getting on fire to turn into, and the copper flat wire is difficult for discovering in the time of slightly breaking, leads to in time solving, finally causes whole circuit short circuit to cause the conflagration accident even, and the security performance is low.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model provides a copper-clad flat wire that security performance is high has solved the problem on copper-clad flat wire security performance ground.

The utility model discloses a realize through following technical scheme:

the utility model provides a copper-clad flat wire that security performance is high, is including the copper conductor that is located the middle part, the copper conductor outside is filled there is silicon rubber insulating material, the silicon rubber insulating material outside covers there is a fire-retardant layer, a plurality of protection tubes have been laid in the fire-retardant layer outside, the protection tube is filled there is the fire extinguishing agent, protection tube outside cover is equipped with the shielding layer, warning pipe has been laid to the shielding layer outside, warning intussuseption is filled with the fluorescent agent, warning outside of tubes side cover is equipped with the polyvinyl chloride layer.

Preferably, the warning tube is filled with a fluorescent agent which is not flammable and does not support combustion.

Preferably, the fire extinguishing agent filled in the protection pipe is dry powder fire extinguishing agent.

Preferably, the shielding layer is made of a carbon fiber filled composite shielding material.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model inhibits the possibility of serious fire due to the excessive load of the copper conductor by the limited silicon rubber insulating material and the limited flame-retardant layer; the fire extinguishing agent is filled in the protection tube, so that the fire prevention strength is enhanced, and the existence of hidden danger is avoided; through filling fluorescent agent in the warning pipe, can let the striking discovery of operator and in time handle when the copper-clad flat wire is cracked, avoid making the accident.

Drawings

Fig. 1 is a sectional view of the present invention.

In the drawings: 1. a copper conductor; 2. a silicone rubber insulating material; 3. a flame retardant layer; 4. protecting the tube; 5. a shielding layer; 6. a warning tube; 7. a polyvinyl chloride layer.

Detailed Description

Figure 1 shows a high-safety copper-clad flat wire in the drawings of the specification, including the copper conductor 1 that is located the middle part, the packing of the 1 outside of copper conductor has silicon rubber insulating material 2, the 2 outside covers of silicon rubber insulating material has a fire-retardant layer 3, a plurality of protection tubes 4 have been laid to the 3 outside on fire-retardant layer, protection tube 4 packs has the fire extinguishing agent, protection tube 4 outside cover is equipped with shielding layer 5, warning pipe 6 has been laid to the 5 outside of shielding layer, warning pipe 6 intussuseption is filled with the fluorescent agent, warning pipe 6 outside cover is equipped with polyvinyl chloride layer 7.

In order to ensure that the staff can be reminded more prominently and simultaneously avoid that the filled substances do not have the functions of combustibility and combustion supporting, further, the fluorescent agent filled in the warning pipe 6 does not have combustibility and combustion supporting.

In order to effectively extinguish fire in time in case of fire, and the fire extinguishing object is a copper-clad flat wire, so that a liquid fire extinguishing agent and a carbon dioxide fire extinguishing agent which is difficult to store cannot be selected, and further, a dry powder fire extinguishing agent is selected as the fire extinguishing agent filled in the protection tube 4.

In order to avoid the influence of an electromagnetic field generated by overlarge current in the copper-clad flat wire on other surrounding components, a certain drainage effect can be achieved through the shielding layer 5, and the carbon fiber filled composite shielding material has the advantages of small density, high specific strength, good chemical stability, good formability and the like, so further, the shielding layer 5 is made of the carbon fiber filled composite shielding material.

The working principle is as follows: the silicon rubber insulating material 2 outside the copper conductor 1 is methyl vinyl silicone rubber, the working temperature range is wide, the working temperature range is-60 to 180 degrees, the bending performance and the low-temperature performance are better, the overall toughness is also increased while fire prevention is ensured, the flame-retardant layer 3 further avoids serious heating caused by overlarge load, and fire is caused, the dry powder extinguishing agent is filled inside the protection tube 4 outside the flame-retardant layer 3 and is mainly used for short circuit fire caused under the condition of fracture, the shielding layer 5 is mainly used for preventing an electromagnetic field generated by overlarge current in the copper conductor 1 from causing adverse effects on other equipment, current can be led into a stratum when the copper-clad flat wire is fractured, the safety coefficient is improved, the warning tube 6 is laid outside the shielding layer 5, the fluorescent agent is filled in the warning tube 6, and can be remarkably convenient for maintenance personnel to see and overhaul in time when the copper-clad flat wire is fractured, the polyvinyl chloride layer 7 has good electrical insulation, good flame retardant property and certain chemical corrosion resistance, and is most suitable for being used as a sheath.

In summary, the present invention is only a preferred embodiment, and should not be limited by the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
