Abstract
The utility model relates to a detection device of a failed solenoid of a direct-current motor, which belongs to the field of the detection equipment of an electric locomotive of a coal mine. The detection device of the failed solenoid of the direct-current motor is characterized by comprising a fuse, a transformer, a rectifier bridge and a direct-current motor, wherein a power cord is connected with the primary side of the transformer by the fuse, the secondary side of the transformer is connected with the input end of the rectifier bridge, the output end of the rectifier bridge is connected with the direct-current motor, and the inside of the direct-current motor is provided with a magnetic pointer which can rotate. By electrifying the direct-current motor, a solenoid which is fixedly connected with the direct-current motor is electrified to generate excitation, and the fault of the solenoid is judged by the magnetic pointer. The method is simple and convenient and has easy operation and high safety and reliability.
Description
Technical field
The utility model provides a kind of direct current generator fault wire package detection device, belongs to mine electric locomotive checkout equipment field.
Background technology
Under coal mine, often use electric locomotive and battery truck.Because use frequent switching on and shutting down, environmental baseline is abominable, be easy to occur situations such as motor damages, burns out, turn-to-turn short circuit.More during the thread-changing bag, can't judge correctly whether other line bag polarity of the polarity of line bag and whole motor are consistent, and whether the unanimity of its magnetic directly influences the serviceable life of motor.
The utility model content
According to above deficiency of the prior art, problem to be solved in the utility model is: a kind of control safety, direct current generator fault wire package detection device easily are provided.
The technical scheme that its technical matters that solves the utility model adopts is: direct current generator fault wire package detection device, it is characterized in that comprising fuse, transformer, rectifier bridge and direct current generator, power lead connects the primary side of transformer by fuse, the secondary side of transformer connects the input end of rectifier bridge, the output terminal of rectifier bridge connects direct current generator, and direct current generator inside is provided with rotary magnetic pointer.
After the energising, rectifier bridge is supplied with direct current to direct current generator.By utilizing of the detection of magnetic pointer to direct current generator, judge the more polarity of thread-changing bag, the correct ew line bag is inserted used.
As prioritization scheme, described magnetic pointer is a bar magnet, and rotary part is set in the middle of the bar magnet.Both can be to adopt in the middle of the bar magnet by the support column rotation, also can be to be bundled in the middle of the bar magnet by fine rule, makes its rotation.Bar magnet can adopt needle to replace.
As prioritization scheme, between the secondary side of described transformer and the rectifier bridge instrument is set, be used to show states such as various concrete electric currents, voltage or power.
The beneficial effect that the utility model direct current generator fault wire package detection device is had is: by powering up to direct current generator, make its fixedly connected line bag energising produce excitation, by the fault of magnetic pointer judgement line bag, method is easy, and is easy to operate, safe and reliable.The utility model is made simple, compact conformation, practicality.
Description of drawings
Fig. 1 is an electrical schematic diagram of the present utility model,
Fig. 2 is a user mode synoptic diagram of the present utility model,
Wherein: 1, fuse 2, transformer 3, instrument 4, rectifier bridge 5, direct current generator 6, needle 7,8, line bag.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, power lead is by the primary side of fuse 1 connection transformer 2, and the secondary side of transformer 2 is by the input end of instrument 3 connection rectifier bridges 4, and the output terminal of rectifier bridge 4 connects direct current generator 5.Direct current generator 5 inside are provided with rotary magnetic pointer.
The magnetic pointer is a bar magnet, and rotary part is set in the middle of the bar magnet.Both can be to adopt in the middle of the bar magnet by the support column rotation, also can be to be bundled in the middle of the bar magnet by fine rule, makes its rotation.Bar magnet can adopt needle to replace.
Power lead provides 380V AC power.Transformer 2 adopts the 3KVA capacity.Rectifier bridge 4 adopts bridge rectifier.
As shown in Figure 2, the line bag in the direct current generator 5 is evenly distributed on the stator of direct current generator.Needle 6 is placed on casing central authorities.Judge the more polarity of thread-changing bag 7,8 by the action that utilizes needle 6, the correct ew line bag is inserted used.
The fuse that the utility model is mentioned, transformer, instrument and rectifier bridge are common prior art, and the technician is grasped by the industry.
Principle of work and process:
After the energising, rectifier bridge with the direct-current power supply direct current generator 5 of 36V or 24V by on the survey line bag 7,8, whether utilize small magnetic needle to judge by the line bag magnetic of the magnetic of survey line bag and whole motor consistent.
