Abstract
The utility model relates to the field of retard solenoid coil technology and discloses a fireproof device of a retarder solenoid coil. The fireproof device comprises a framework, a varnished wire winding and a fireproof coating. The varnished wire winding is wound on the outer side of the framework and the fireproof coating is fixed to the outer side of the varnished wire winding. The fireproof device is simple in structure and easy to use. Through vacuum glue pouring and curing and with the fireproof coating coated on the outside, the fireproof device effectively prevents outbreak of fire caused by short circuit of the coil, thereby reducing potential safety hazards greatly.
Description
Technical field
The utility model relates to retarder solenoid technical field, is a kind of retarder solenoid firebreak device.
Background technology
Current vortex retarder generally is comprised of stator, rotor and fixed support.During retarder work, energising produces magnetic field in the stator coil, and rotor rotates with power transmission shaft.The magnetic line of force that the rotor cutting stator produces, thereby at the Vorticose induced current of the inner generation of rotor disk.Like this, stator will apply an electromagnetic force that hinders rotor to rotor, thereby produces braking moment.Simultaneously, eddy current has the rotor disk internal circulation of certain resistance, because the thermal effect of resistance can be electric energy conversion heat energy, like this, the kinetic energy of Vehicle Driving Cycle just finally is converted into heat energy by electromagnetic induction and resistance heating and distributes.The current vortex retarder solenoid is because accident on fire then very easily occurs such as the winding wire short circuit in the long-term large current work of high load capacity, and the traffic safety of vehicle is threatened.
Summary of the invention
The utility model provides a kind of retarder solenoid firebreak device, has overcome the deficiency of above-mentioned prior art, and it can solve the current vortex retarder solenoid owing to the long-term large current work of high load capacity, and the problem of accident on fire then very easily occurs in the winding wire short circuit.
The technical solution of the utility model is achieved like this: a kind of retarder solenoid firebreak device, comprise skeleton, enamelled wire winding and fire resistant coating, and be wound with the enamelled wire winding in the outside of skeleton, be fixed with fire resistant coating in the enamelled wire winding outside.
Comprise upper frame, winding body and lower frame with upper skeleton, be fixed with winding body between upper frame and the lower frame, the external diameter of upper frame and lower frame is greater than the external diameter of winding body, and the enamelled wire winding technique is on winding body.
Above enamelled wire winding is wound on the winding body by vacuum glue pouring curing.
The utility model is simple in structure, and is easy to use, solidify by adopting vacuum glue pouring, and the external application fire resistant coating, effectively prevent the phenomenon that coil short is on fire, thereby greatly lowered potential safety hazard.
Description of drawings
Fig. 1 is that master of the present utility model looks sectional structure chart.
Coding among the figure is respectively: 1 is the enamelled wire winding, and 2 is fire resistant coating, and 3 is upper frame, and 4 is winding body, and 5 is lower frame.
Embodiment
As shown in Figure 1, a kind of retarder solenoid firebreak device comprises skeleton, enamelled wire winding 1 and fire resistant coating 2, is wound with enamelled wire winding 1 in the outside of skeleton, is fixed with fire resistant coating 2 in enamelled wire winding 1 outside.Can effectively prevent the phenomenon that coil short is on fire by fire resistant coating 2 is set, thereby greatly lower potential safety hazard.
As shown in Figure 1, skeleton comprises upper frame 3, winding body 4 and lower frame 5, is fixed with winding body 4 between upper frame 3 and the lower frame 5, and the external diameter of upper frame 3 and lower frame 5 is greater than the external diameter of winding body 4, and enamelled wire winding 1 is wound on the winding body 4.In order to increase fire line, enamelled wire winding 1 is wound on the winding body 4 by vacuum glue pouring curing.
