Abstract
The utility model discloses a kind of DC motor rotor cable bond temperature measuring equipment.Comprise temperature sensor, data collector, wireless data dispensing device, receive data by wireless device, remote computer.Temperature sensor is arranged on motor rotor cable bond, along with rotor cable bond rotates, gather the temperature parameter of cable bond, and signal is connected on harvester, data are sent to wireless launcher by harvester, data are sent to radio receiver by WiFi technology by wireless launcher, data are sent to host computer by Industrial Ethernet by radio receiver, host computer shows the temperature data uploaded, analyze, preserve, if cable bond temperature is too high or temperature raises too fast, then alarm can be carried out, avoid occurring that the too fast rising of coil Yin Wendu is breakdown.These temperature datas are also for the optimal design of large-sized DC motor armature rotor winding provides important evidence.
Description
Technical field
The utility model relates to a kind of temperature-detecting device of DC motor rotor cable bond.
Background technology
Cable bond is an ingredient of DC motor rotor armature winding.Motor is uneven if there is armature voltage in operational process, or rotor interturn short-circuit, or brush and brush carrier Long contact time bad, capital causes rotor cable bond temperature to raise, can cable bond be burnt time serious, puncture rotor windings insulation, cause major accident.Cable bond is positioned at DC motor rotor armature end-connections, in motor operation course, be in rotation status, and this brings very large difficulty, the effective ways that prior art does not address this problem just to cable bond temperature survey.
Summary of the invention
The purpose of this utility model is to provide a kind of DC motor rotor cable bond temperature-detecting device, at on-line monitoring and motor cable bond temperature in operational process can be recorded, judge whether armature balances direct current motor, for unit safety operation, avoid the generation of accident, provide scientific basis, for the armature optimal design of direct current motor provides evidence.
The technical solution of the utility model is: direct current motor is often organized on cable bond and is separately installed with STT-SA1 type Pt100 temperature sensor, the output signal of STT-SA1 type Pt100 temperature sensor is connected on the input terminal of the NI9217RTD type data collector be fixed on motor rotor by lead-in wire, NI9217RTD type data collector transfers data on NIWLS/ENET900 type wireless launcher, NIWLS/ENET900 type wireless launcher transfers data to D-LinkDI-8004 type radio receiver by WiFi technology, temperature data is sent to remote computer by Industrial Ethernet by D-LinkDI-8004 type radio receiver, remote computer is by process analysis temperature data, judge direct current motor whether normal operation.
Remote computer Real-Time Monitoring also records measured temperature data, and for ensureing the safe operation of direct current motor, the optimal design of armature winding provides important evidence.
The utility model achieves direct, reliable, the real-time Measurement accuracy of rotor cable bond temperature in direct current motor operational process, avoids the various errors that indirect inspection is introduced.It is simple that the utility model has structure, picking rate fast (NI9217RTD type data collector single channel acquisition time is 2.5ms), transmission speed fast (adopting WiFi technology NIWLS/ENET900 type wireless launcher wireless transmission rate to be 128Mbps), long transmission distance (covering radius of WiFi technology is about 100 meters), antijamming capability is strong, the features such as the bit error rate is low.The temperature data of the temperature detection program energy real-time analysis of remote computer, display, storage of collected, reports to the police when DC motor rotor cable bond temperature is too high, for direct current motor safe operation provides important guarantee.
