Technical field
The utility model relates to high-pressure system apparatus field, particularly relates to a kind of high-voltage wiring harness can monitoring own temperature.
Background technology
High-voltage wiring harness is as the key part and component of high-voltage electric system, the safety run for electric automobile is given security, but because high-voltage wiring harness operationally can generate heat, high-voltage wiring harness product in the market all can not monitor self temperature rise situation in the course of the work, thus may occur causing danger on fire because high-voltage wiring harness temperature is too high, cause high-voltage wiring harness potential safety hazard in use.
Summary of the invention
The technical problems to be solved in the utility model, is the high-voltage wiring harness providing a kind of temperature to monitor, and realizes Real-Time Monitoring high-voltage wiring harness variations in temperature, to take safety measures in time, eliminates the too high potential safety hazard brought of temperature.
The utility model is achieved in that the high-voltage wiring harness that a kind of temperature can be monitored, the two ends of described high-voltage wiring harness respectively with power supply unit, power consumption equipment connects, described power supply unit connects one first signal ground, described power consumption equipment connects a secondary signal ground, described first signal ground and secondary signal ground are altogether, and this high-voltage wiring harness comprises a core from inside to outside, one inner insulating layer, one screen and an external insulation layer, a thermistor is provided with between the external insulation layer of described high-voltage wiring harness and screen, the two ends of described thermistor connect one first signal conductor and a secondary signal wire respectively, described first signal conductor and secondary signal wire are drawn along the two ends of high-voltage wiring harness respectively,
Be connected to described first signal conductor and secondary signal, described secondary signal wire is connected with the cpu controller in power supply unit, described cpu controller is connected with the first signal ground, the temperature of described cpu controller to thermistor is monitored, stop the output of high-tension electricity when the variations in temperature monitoring thermistor exceedes certain value, avoid excessive temperature to cause on fire.
Further, if described power consumption equipment with controller and the controller of power consumption equipment and secondary signal be connected, then described first signal conductor connect in power consumption equipment with the controller that is connected of secondary signal ground, otherwise the first signal conductor directly connects secondary signal ground.
The utility model has the advantage of: the utility model is by establishing a thermistor at high-voltage wiring harness; realize its variations in temperature of Real-Time Monitoring in the high-voltage wiring harness course of work; can can take measures in time when monitoring large variations in temperature; thus eliminate the too high potential safety hazard brought of temperature, play defencive function.
Accompanying drawing explanation
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is high-voltage wiring harness schematic diagram of the present utility model.
Fig. 2 is the high-voltage wiring harness of band monitoring temperature.
Embodiment
Refer to shown in Fig. 1 and Fig. 2, the high-voltage wiring harness 100 that a kind of temperature of the utility model can be monitored, the A end of described high-voltage wiring harness 100 connects power supply unit E, the B end of high-voltage wiring harness 100 connects power consumption equipment F, described power supply unit E connects one first signal ground C, described power consumption equipment F connects a secondary signal ground D, described first signal ground C and secondary signal ground D is altogether, and this high-voltage wiring harness 100 comprises a core 1 from inside to outside, one inner insulating layer 3, one screen 4 and an external insulation layer 6, a thermistor 5 is provided with between the external insulation layer 6 of described high-voltage wiring harness 100 and screen 4, the two ends of described thermistor 5 connect one first signal conductor 21 and a secondary signal wire 22 respectively, described first signal conductor 21 and secondary signal wire 22 are drawn along the two ends of high-voltage wiring harness 100 respectively, the resistance of thermistor 5 changes with the change of the temperature of high-voltage wiring harness 100, therefore the variations in temperature of high-voltage wiring harness 100 just can be known according to the change monitoring thermistor 5 resistance, when the temperature of high-voltage wiring harness 100 raises, the resistance step-down of the thermistor 5 monitored, when resistance low to certain value time, the output by cutoff high electricity avoids high-voltage wiring harness 100 on fire because of continuous high temperature,
If power consumption equipment F with controller (not shown) and the controller (not shown) of power consumption equipment F and secondary signal ground D be connected, then the first signal conductor 21 connects the controller (not shown) be connected with secondary signal ground D in power consumption equipment F, thus reach the connection of the first signal conductor 21 and secondary signal ground D, otherwise the first signal conductor 21 directly connects secondary signal ground D; Described secondary signal wire 22 is connected with the cpu controller in power supply unit, described cpu controller is connected with the first signal ground C, the temperature of described cpu controller to thermistor 5 is monitored, also thermistor 5 two ends signal conductor can be detected with universal instrument, measure the resistance of thermistor thus learn the temperature of high-voltage wiring harness, stop the output of high-tension electricity when the variations in temperature monitoring thermistor 5 exceedes certain value, avoid excessive temperature to cause on fire.
Although the foregoing describe embodiment of the present utility model; but be familiar with those skilled in the art to be to be understood that; specific embodiment described by us is illustrative; instead of for the restriction to scope of the present utility model; those of ordinary skill in the art, in the modification of the equivalence done according to spirit of the present utility model and change, should be encompassed in scope that claim of the present utility model protects.
