Abstract

The invention relates to the field of floor heating devices, in particular to an on-instant-heating quick heat generating wire which comprises a heat generating wire body, an insulating layer, a grounding wire, a shielding layer and a protective jacket. The heat generating wire body is divided into a cold wire and a hot wire, the cold wire is a tinned copper wire, the hot wire is chrome-nickel alloy, and the weight percentage of chrome and nickel in the chrome-nickel alloy is 3:7; the cold wire and the hot wire are connected by stranding, and lay ratio of stranding is not smaller than 12; a power source wire is arranged on the outer layer of the heat generating wire body, the power source wire and the heat generating wire body are arranged in the shielding layer side by side, and an electricity leaking protection switch is arranged at a position where the power source wire is connected with a power source. When the heat generating wire body is damaged, the shielding layer is conductive, and the electricity leaking protection switch cuts off a power source, so that the technical defect that heat generating wires are slow in temperature rise and many in potential safety hazards in the prior art is overcome; the quick heat generating wire can realize instant heating immediately after being powered on and is high safety index.

Description

technical field [0001] The invention relates to the field of floor heating devices, in particular to a fast heating wire that is heated when energized. Background technique [0002] In recent years, with the deterioration of air quality, smog has become a hot word. Air pollution has caused serious social and physical problems to people. Therefore, the government has clearly defined the scope and time limit for prohibiting the use of highly polluting fuels such as coal. It has accelerated the elimination of the traditional boiler heating mode, and promoted the energy-consuming units to actively carry out clean energy transformation. As a new energy-saving and environmentally friendly product, electric floor heating has been applied to winter heating and has been widely used. The heating wire is a heating device installed in the floor heating pipe. The heating wire is a special cable that generates heat due to its own resistance after the metal conductor is energized, dissipat...
