Abstract
The utility model relates to a switching device for a plurality of frequency transformer electric motor which is mainly composed of a switching switch 1-16 and an AC frequency conversion bus 17-19 that connected between the frequency transformer and the electric motor. The frequency transformer and the electric motor can be switched at random according to needs. In case of failure in the frequency transformer of the key machines for the drive, the frequency transformer can be used for emergency substitution, thereby preventing the halt of the key machine.
Description
The utility model relates to oil-well drilling equipment, is a kind of when driving the frequency converter failure of important machinery, can realize substituting easily at any time with the frequency converter that drives other less important plant equipment the device of fault frequency converter; Can also replenish drive the deficiency of the transducer power of important machinery with non-visual plant frequency converter, guarantee not reason frequency converter failure and can not normally moving of important manufacturing machine.
Oil frequency conversion rig does not use such switching device shifter at present, and when a certain frequency converter broke down, the plant equipment that this frequency converter drives can only quit work and influence operate as normal; When transducer power is not enough, can only use powerful frequency converter instead, increased equipment investment.
The purpose of this utility model just provides a kind ofly can carry out device for switching easily between many frequency converters and their institute's drive electric motor.The purpose of this utility model is achieved in that it mainly is made up of diverter switch 1～16, AC frequency conversion bus 17～19, and they are connected between frequency converter and the motor.
Frequency converter DA1～DA3 can drive winch motor M1, M2 arbitrarily.
Frequency converter DA2, DA3 can drive 1#～2# pump motor M3～M6 arbitrarily,
Frequency converter DA3, DA4 can drive rotary tray motor M7 arbitrarily.
Diverter switch can be that contactor also can be electrically operated circuit breaker or other automatic electric switch elements.
The utility model advantage is: can switch arbitrarily according to need of work between frequency converter and the motor, can substitute with its frequency converter is emergent when the frequency converter that drives important machinery breaks down, can not cause important machinery out of service.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
Referring to Fig. 1, the utility model mainly is made up of diverter switch 1～16, AC frequency conversion bus 17～19, and they are connected between frequency converter and the motor.
Frequency converter DA1～DA3 can drive winch motor M1, M2 arbitrarily, its connected mode is: DA1～DA3 is connected with AC frequency conversion bus 17～19 respectively, one end of diverter switch 1,2,3 is connected with AC frequency conversion bus 17～19 respectively, and the other end is connected with winch motor M1; An end of 4,5,6 of tangent line switch is connected with AC frequency conversion bus 17～19 respectively, and the other end is connected with winch motor M2.
Frequency converter DA2, DA3 can drive 1#～2# pump motor M3～M6 arbitrarily, and its connected mode is: frequency converter DA2, DA3 are connected with AC frequency conversion bus 17,18 respectively; Diverter switch 7 and 8,9 and 10,11 and 12,13 and 14, an end be connected with AC frequency conversion bus 17,18 respectively, the other end is connected to respectively on pump motor M3～M6 for every group.
Frequency converter DA3, DA4 are connected to rotary tray motor M7 by diverter switch 15,16.
Diverter switch can be that contactor also can be electrically operated circuit breaker or other automatic electric switch elements.
