Abstract

The invention belongs to the technology of electric resistance and electric heating, and relates to a non-inductance electric heating resistance device which can be used as a resistor. The non-inductance electric heating resistance device comprises at least one electric heating tube without inductance after electrification. The electric heating tube comprises an outer tube of the electric heating tube, an insulating ring and a fastener which are positioned at two ends of the outer tube of the electric heating tube, wiring terminals inserted to the insulating ring, spiral resistance wires penetrating into the outer tube of the electric heating tube, and a heat-conducting insulating material filled between the resistance wire and the outer tube of the electric heating tube; and the number of the resistance wires is two, the two resistance wires are arranged side by side and connected in parallel between the wiring terminals at two ends, and the spiral directions of the two spiral resistance wires are opposite. The non-inductance electric heating resistance device can be used as the resistor and an electric heater, and does not generate the inductance to circuits during working.

Description

technical field [0001] The invention belongs to resistance and electric heating technology, and relates to a non-inductance electric heating resistance device which can be used as a resistor. Background technique [0002] In some electrical control circuits of industrial and marine equipment with relatively large power, resistive electric heaters can be used as resistors, so that they can use the heat generated by their power consumption while satisfying the electrical functions in the circuit. To heat the medium (such as water), these heated medium can be further used to achieve the purpose of saving energy. Such an electric heating device is essentially an electric heating resistance device. However, the electric heating tube of the general electric heating device is a heating function device, and the heating resistance wire in the tube is made by winding a certain length of spiral with a high resistance electric heating alloy wire. This helical heating resistance wire w...
