Abstract
The utility model provides a novel wire connecting structure of electrical heating elements. The wire connecting structure comprises three electrical heating elements, three connecting copper sheets, and a three-phase power line. Two ends of each connecting copper sheet are connected with one end of the electrical heating elements, respectively. The three connecting copper sheets and the three electrical heating elements are connected to form a triangular structure. Three wires A, B, and C of the three-phase power line are fixedly connected with one ends with same pole of the three electrical heating elements, respectively. The advantages and active effects of the wire connecting structure are that a wire is saved by using three-phase three-wire system so that not only is cost saved, but also construction and maintenance are facilitated, and that a problem in one phase does not affect the other phases.
Description
Technical field
The utility model belongs to the mode of connection technical field of electric heating element.
Background technology
Traditional electric heating element wiring construction mostly adopts Y type draw bail, namely adopt the three-phase four-wire system wiring construction that center line is arranged, this mode of connection applicable surface is wider, but has following several respects defective: 1, when components and parts are more, time-consuming when wiring and cabling; 2, maintenance difficulty when going wrong; 3, for preventing that a certain electric heating element of going up mutually from damaging when more, neutral line current is excessive, and it is identical with the wire diameter of three phase supply line that the wire diameter of zero line should adopt, and project cost is high, particularly electric heating element more, when thread is longer, problem is more outstanding.
Summary of the invention
Problem to be solved in the utility model provides a kind of easy-to-connect, uses the △ shape bind mode of the three phase mains of safe, with low cost electric heating element.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of having novel wiring structure of electric heating element, comprise that three electric heating elements, three connect copper sheet and three-phase power line, the two ends of each described connection copper sheet connect respectively an end of an electric heating element, three connection copper sheets and three electric heating elements connect into triangular structure, and three wire A, B of described three-phase power line, C are fixedly connected with the same utmost point of three electric heating elements respectively.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, be three-phase three-wire system, save 1 zero line, so not only saved cost, and construction and easier when keeping in repair; And when certain circuitry phase went wrong, other was mutually unaffected.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Among the figure:
1, electric heating element 2, connection copper sheet 3, three-phase power line
Embodiment
As shown in Figure 1,
A kind of having novel wiring structure of the utility model electric heating element, comprise that three electric heating elements 1, three connect copper sheet 2 and three-phase power line 3, the two ends of each described connection copper sheet 2 connect respectively an end of an electric heating element 1, three connection copper sheets 2 and three electric heating elements 1 connect into triangular structure, and three wire A, B of described three-phase power line 3, C are fixedly connected with the same utmost point of three electric heating elements 1 respectively.
The course of work of this example is:
Three wire A, B, the C of described three-phase power line 3 are connected with the positive pole of three electric heating elements 1 respectively, and to its energising, three connect copper sheet 2 and play the function that conduction connects.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
