Abstract
The invention discloses a heating cable, which relates to an electrothermal heat preservation device, comprising a three-phase power line. The three-phase power line comprises a live wire, a neutral wire, an earth wire and insulating outer sheaths, wherein the live wire is connected with a PTC (Positive Temperature Coefficient) temperature controller and the other end of the PTC temperature controller is connected with a resistance wire; the neutral wire is connected with another resistance wire; the tail ends of the two resistance wires are mutually connected; the earth wire is connected with a second earth wire; and both the resistance wires and the second earth wire are externally wrapped with the heat-conductive insulating outer sheaths. By adopting the resistance wires as heating elements, the heating cable has long service life and low cost; through the connected PTC temperature controller, the heating cable is automatically started to heat when the temperature is low; and after the temperature rises, the internal resistance of the heating cable is close to infinity, and the circuit is disconnected to stop supplying heat.
Description
Technical field
The present invention relates to a kind of electric heating and thermal insulation device.
Background technology
Heating tape utilizes electric tracing equipment that electric energy is converted into heat energy exactly, by direct or indirect heat exchange, replenish by the hot equipment of companion by heat that insulation material lost, and adopt temperature to control, reach the temperature of following the tracks of and control medium in the hot equipment of companion, make it to maintain on the reasonable and economic level.
The hot device of existing companion, its heater element adopts carbon fiber, and its life-span is short, cost is high.
Summary of the invention
The objective of the invention is: the heating tape that a kind of life-span is long, cost is low is provided.
The object of the present invention is achieved like this: a kind of heating tape, comprise a three-phase power line, and described three-phase power line comprises live wire, zero line, ground wire, insulation outer jacket; Described live wire is connected with the PTC thermostat, and the other end of PTC thermostat is connected with a resistance wire; Described zero line is connected with another root resistance wire, and the end of described two resistance wires interconnects; Described ground wire is connected with second ground wire; The outer wrap heat conductive insulating outer jacket of the described resistance wire and second ground wire.
The invention has the beneficial effects as follows: adopted resistance wire as heater element, its life-span is long, cost is low, by the PTC thermostat that connects, when temperature is low, starts heating automatically; After temperature raise, its internal resistance was near infinitely great, and circuit disconnects, and stops heat supply.
As a further improvement on the present invention, described PTC thermostat is provided with the injection moulding sealant outward, reaches the effect of waterproof sealing.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Wherein, 1-insulation outer jacket, 2-live wire, 3-zero line, 4-ground wire, 5-PTC thermostat, 6-resistance wire, another root resistance wire of 7-, 8-second ground wire, 9-heat conductive insulating outer jacket, 10-injection moulding sealant.
