Embodiment
In order to which technical characteristic, purpose and the effect of the present invention is more clearly understood, now control illustrates this hair
Bright embodiment.
A kind of intelligent temperature control electric-heating belt of the present invention, is referred to shown in Fig. 1, in its preferred embodiment, the intelligent temperature
Control electric-heating belt includes accompanying-heat cable and accompanying-heat cable control cabinet；The accompanying-heat cable is by conductive plastics 1 and two parallel intervals
The power supply buses of setting combine, and the conductive plastics 1 electrically connects with two power supply buses, the He of conductive plastics 1
Power supply buses are coated with insulation crust 4；The accompanying-heat cable control cabinet is provided with the electrothermal relay 6 and contactor 7 being connected in series；
The accompanying-heat cable control cabinet is connected to one end that the conductive plastics 1 electrically connects with the power supply buses, with the conductive modeling
The series connection of material 1, forms accompanying-heat cable performance loop, as shown in Figure 2；Conductive carbon granules is contained in the conductive plastics 1.
Contain conductive carbon granules in the conductive plastics 1 of accompanying-heat cable, when being powered to power supply buses, conductive carbon granules is just at two
Circuit is formed between power supply buses, in every accompanying-heat cable, between bus formation electrical connection circuit number with temperature shadow
Ring and change.During temperatures cool around accompanying-heat cable, conductive plastics 1 produces the contraction of scintilla and connects conductive carbon granules
Circuit is formed, electric current flows through these circuits, accompanying-heat cable is generated heat；When the temperature increases, conductive plastics 1 produces the swollen of scintilla
Swollen, conductive carbon granules separates gradually, causes Circuit Interrupt, and resistance rises, and accompanying-heat cable reduces power output automatically.Work as environment temperature
When turning cold, plastics are returned to scintilla contraction state again, and accompanying-heat cable heating power is again automatic to be risen, it is achieved thereby that heat tracing is electric
The effect that cable heats automatically when turning cold.
But because the auto switching temperature range of conductive plastics 1 is wide, be unfavorable for scene power conservation requirement, it is all devise it is a set of
Temperature control regulating loop, i.e., by adjusting the normal start and stop of the temperature control accompanying-heat cable in accompanying-heat cable control cabinet, as described above,
Temperature controlled function can be realized using electrothermal relay 6, set the zero point of electrothermal relay 6, realize automatic temperature-adjusting
The input of the accompanying-heat cable of control and disconnection, and the auto switching of the material of conductive plastics 1 is formed dual as standby start-up and shut-down control
Protective effect.
The intelligent temperature control electric-heating belt of the present invention as described above, in its preferred embodiment, the conductive plastics 1 and institute
State and connected via fixed fastener 3 between insulation crust 4.Pass through the connection of fixed fastener 3 so that conductive plastics 1 is firmly fixed
In insulation crust 4, because intelligent temperature control heating tape is made up of conductive plastics 1 and two additional insulating barriers of parallel bus, due to
This parallel connection structure, the conductive plastics 1 of all accompanying-heat cables any (in certain limit) at the scene can be cut, arbitrarily
Connection, facilitate site operation, reduce the cost of the heat tracing equipment such as the moistureproof defrosting of power supply buses, improve operating efficiency.
The intelligent temperature control electric-heating belt of the present invention as described above, in its preferred embodiment, the accompanying-heat cable control
The air switch 2 being connected in series with the electrothermal relay 6 and contactor 7 is provided with case.The air switch of installation, can be preferably
Protect the safety of the accompanying-heat cable performance loop.
The intelligent temperature control electric-heating belt of the present invention as described above, in its preferred embodiment, the accompanying-heat cable control
Temperature controller is additionally provided with case, as shown in figure 3, the temperature controller is provided with temperature control auxiliary contact 51, and the temperature control aids in
Connected in the accompanying-heat cable performance loop with the conductive plastics 1 contact.The temp probe 5 of the temperature controller is arranged on
In the intelligent temperature control electric-heating belt of the present invention, and the temperature of the power supply buses or conductive plastics 1 can be directly detected, by the temperature
The temperature control auxiliary contact of degree controller control are connected with the accompanying-heat cable performance loop, and control the energization of the conductive plastics 1
And disconnection, the heat tracing function of control conductive plastics 1., can with reference to the co- controlling of the electrothermal relay contact 61 in electrothermal relay
Form multiple temperature control effect.
The intelligent temperature control electric-heating belt of the present invention as described above, in its preferred embodiment, the cable work loop
In be in series with degaussing switch auxiliary contact 8.The degaussing switch auxiliary contact 8 of the degaussing switch of generating set major loop are arranged at institute
State in accompanying-heat cable performance loop and connected with conductive plastics 1, removed by compressor emergency shutdown and the heating protection against the tide for starting control accompanying-heat cable
The operation of frost.
The intelligent temperature control electric-heating belt of the present invention, can combine various control logic, and switching control is carried out to accompanying-heat cable,
The control of heat tracing function is very intelligent, while also provides multiple security protection, ensures the normal operation of heat tracing function.As above institute
The preferred embodiment stated, after compressor emergency shutdown, degaussing switch tripping, its degaussing switch auxiliary contact 8 also close, at the same time
The low entry condition low with the temperature of temperature controller of the temperature of conductive plastics 1, and after major loop is without excessively stream, accompanying-heat cable input；When
Degaussing switch closure, temperature controller temperature are high, conductive plastics temperature is high, and any one condition of major loop excessively stream, accompanying-heat cable exits
Operation.
Because the temperature of Self-controlled accompanying-heat cable automatically adjusts, therefore there is the unexistent advantage of other accompanying-heat cables,
It will not cause temperature too high and damage cable in itself, allow multiple juxtaposition during installation and without hyperthermia and superheating point and burn it
Consider.
