Abstract
The utility model relates to a single -ended electric heating element of three -phase, including the electrothermal tube outer tube, the electrothermal tube outer tube has generate heat district and cold junction, and it has insulating filler material to fill in the inner chamber of electrothermal tube outer tube, characterized by: electrothermal tube outer pipe inner cavity's the district that generates heat sets up the load of three -phase heating wire, sets up the cold needle of three -phase at electrothermal tube outer pipe inner cavity's cold junction. The load of three -phase heating wire is adopted the three -phase connection and is connected with the cold needle of three -phase, and the tip of the cold needle of three -phase stretches out the tip of cold junction. The utility model has the advantages of it is following: (1 ) the utility model discloses a single electric heating element adopts three phase structures, an effective list heating element's who improves power, (2 ) electricity heating element is when the combination is used, and electric heating element quantity needn't be subject to 3 multiple also can three -phase balance.
Description
Technical field
This utility model is related to a kind of electrical heating elements, and especially a kind of single-ended electrical heating elements of three-phase, belong to heating unit
Part technical field.
Background technology
In prior art, general single-ended electrical heating elements are all single-phase, under a fixed structure, with the increasing of power
Plus, electric current also increases, but the section of eduction rod is certain, i.e., its maximum carrying capacity is certain, so its peak power
Will be limited by maximum carrying capacity.And current single-ended electrical heating elements, when being applied in combination, its quantity is generally required to be 3 multiple
To realize three-phase equilibrium.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of single-ended electrical heating unit of three-phase
Part, using three-phase structure, under same power, improves the power of single single-ended electrical heating elements.
According to the technical scheme that this utility model is provided, the single-ended electrical heating elements of the three-phase, including electrothermal tube outer tube, electricity
Heat pipe outer tube has hot zone and cold end, is filled with insulation filling material in the inner chamber of electrothermal tube outer tube；It is characterized in that：Institute
The hot zone for stating electrothermal tube outer tube bore arranges the load of three-phase heating wire, arranges three-phase in the cold end of electrothermal tube outer tube bore cold
Pin.
Further, three-phase heating wire load is linked using three, and is connected with the cold pin of three-phase, the end of the cold pin of three-phase
Stretch out the end of cold end in portion.
Further, the three-phase heating wire load is using star connection or triangle junction.
This utility model has advantages below：
（1）Single electrical heating elements of the present utility model adopt three-phase structure, the work(of the single heating element heater for effectively improving
Rate；
（2）Electrical heating elements described in the utility model when being applied in combination, electrical heating elements quantity be not necessarily limited by 3 times
Number also can three-phase equilibrium.
Description of the drawings
Fig. 1 is the structural representation of the single-ended electrical heating elements of three-phase described in the utility model.
Specific embodiment
With reference to concrete accompanying drawing, the utility model is described in further detail.
As shown in Figure 1：The single-ended electrical heating elements of the three-phase include electrothermal tube outer tube 1, three-phase heating wire load 2, insulation
The cold pin 4 of packing material 3, three-phase, hot zone A, cold end B etc..
As shown in figure 1, the single-ended electrical heating elements of three-phase described in the utility model, including electrothermal tube outer tube 1, electrothermal tube outer tube
1 has hot zone A and cold end B（That is not hot zone）；Insulation filling material 3 is filled with the inner chamber of the electrothermal tube outer tube 1；
Three-phase heating wire load 2 is set in the hot zone A of 1 inner chamber of electrothermal tube outer tube, is set in cold end B of 1 inner chamber of electrothermal tube outer tube
Put the cold pin of three-phase 4（That is conducting rod）；The three-phase heating wire load 2 is linked using three（As star connection or triangle join
Knot）, and be connected with the cold pin of three-phase 4, the end of cold end B is stretched out in the end of the cold pin of three-phase 4.
This utility model effectively improves the power of single electrical heating elements using the electrical heating elements of three-phase structure；And
When being applied in combination, electrical heating elements quantity is not necessarily limited by 3 multiple and can also realize three-phase equilibrium.
