Description
Technical field
This utility model relates to Machinery Control System, specifically refers to a kind of frequency conversion motor automatic maintenance system of insulation.
Background technology
In modern industry produces, motor applications scope is quite extensive, and its power consumption is also quite surprising, and China's industrial energy consumption accounts for the 70% of total energy consumption, and wherein energy consumption of electrical machinery accounts for the 60%-70% of industrial energy consumption；Plus non-industrial motor energy consumption, energy consumption of electrical machinery accounts for more than the 50% of total energy consumption, improves the service efficiency of motor, thus improving the economic benefit of factory, this becomes the problem that first a large amount of energy enterprise solves.At present, motor variable-frequency speed-regulating technology has become as a main development direction of Modern Electrical Drive technology.The advantages such as its remarkable speed adjusting performance, significant power savings, improve the operating condition of existing equipment, improves security reliability and the utilization rate of equipment and installations of system, extension device service life are embodied fully along with constantly expanding of application.But variable frequency adjustment motor there is also following defect: frequency conversion motor is shut down in alternate processes long-time, by surrounding high humidity, impact that the temperature difference is big, the easy moisture absorption of stator and rotor winding insulation thing and make insulation resistance dramatic decrease so that it is electrical strength is substantially reduced.If now direct-electrifying start, then be susceptible to winding puncture, short circuit accident.And if the important motor such as boiler induced-draft fan can not run crucial moment in time, have a strong impact on the safety in production of our factory, and bring great economic loss.
Summary of the invention
The purpose of this utility model is aiming at frequency conversion motor and shuts down in alternate processes long-time; by surrounding high humidity, impact that the temperature difference is big, insulate dramatic decrease, it is impossible to a standby difficult problem; when utilizing frequency conversion motor low speed jiggering; it is possible not only to keep the insulation of motor stator, and also ensure that the mechanical performance that rotor is good, therefore; when frequency conversion motor is shut down and is in holding state; transferred to low speed jiggering to run, it is possible to effectively prevent motor from making moist, it is ensured that frequency conversion motor can put into operation at any time.
For achieving the above object, a kind of frequency conversion motor insulation designed by this utility model keeps system automatically, including control system, motor, load and air-introduced machine, described motor is connected with load, and described motor is connected with air-introduced machine, described control system is connected to governing system, and described governing system is connected with motor；Described governing system includes cranking system and follows the trail of load frequency conversion system；Described tracking load frequency conversion system is connected with air-introduced machine.
Further, described control system is provided with dish machine and controls switch and run control switch, and described dish machine controls switch and is connected with cranking system, and the described control switch that runs is connected with following the trail of load frequency conversion system.
Further, described control system is provided with display device, and the convenient running status to system gets information about.
The beneficial effects of the utility model: this utility model solves insulation dramatic decrease after frequency conversion motor is stopped transport by automatic control system, cause the difficult problem that frequency conversion motor cannot run, can be widely applied to, on the important load motor that boiler induced-draft fan motor, blast furnace blower motor etc. do not allow to stop transport easily, there is high promotional value.
Accompanying drawing explanation
Fig. 1 is the structure connection diagram that frequency conversion motor insulation keeps system automatically；
In figure: control system 1, motor 2, load 3, air-introduced machine 4, governing system 5, cranking system 6, follow the trail of load frequency conversion system 7, dish machine control switch 8, run control switch 9.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail:
As it is shown in figure 1, a kind of frequency conversion motor insulation keeps system automatically, including control system 1, motor 2, load 3 and air-introduced machine 4, described motor 2 is connected with load 3, described motor 2 is connected with air-introduced machine 4, and described control system 1 is connected to governing system 5, and described governing system 5 is connected with motor 2；Described governing system 5 includes cranking system 6 and follows the trail of load frequency conversion system 7；Described tracking load frequency conversion system 7 is connected with air-introduced machine 4；Described control system 1 is provided with dish machine and controls switch 8 and run control switch 9, and described dish machine controls switch 8 and is connected with cranking system 6, and described operation controls to switch 9 and is connected with following the trail of load frequency conversion system 7, and control system 1 is provided with display device 10.
Operation principle: detected by the display device 10 of control system 1, when control operation control switch 9 control air-introduced machines 4 and motor 2 are properly functioning, follow the trail of load frequency conversion system 7 and be automatically adjusted air-introduced machine 4 and the rotating speed of motor 2 according to the height of load, to reach energy-saving effect；By dish machine control switch 8 control air-introduced machines 4 and motor 2 standby time, air-introduced machine 4 and motor 2 is controlled with rotating speed low speed jiggering by cranking system 6, the insulation values making air-introduced machine 4 and motor 2 remains at normal range more than, it is ensured that overall equipment can put into operation at any time.
