Description
Technical field
The utility model relates to a kind of isolating switch position, belongs to the power system transformer substation technical field of automation.
Background technology
The isolating switch mechanical realization variation that at present electric power system is used, but all can be abstract in adopting vertical-transmission bar rotation of motor-driven, again by what machine driving, the movable contact spring of final driving isolation switch is clamped the stationary contact bar, is judged to be " combined floodgate " position; When the motor reverse rotation, drive the motion of vertical-transmission bar, movable contact spring breaks away from the stationary contact bar, arrives an assigned address, is judged to be " separating brake " position.In power system operation and the operating process, the judgement that whether isolating switch is in assigned address is extremely important, and the at present collection of isolating switch position is all by mechanical assistance switch of assembling, by mechanical linkage and vertical-transmission bar synchronous rotary.When isolating switch is in " combined floodgate " position, just so that the closing of contact of auxiliary switch one side; When isolating switch is in " separating brake " position, so that the closing of contact of auxiliary switch opposite side.Judge the physical location of isolating switch by the closure of auxiliary switch contact.The auxiliary switch contact is a switching value signal, only can reflect final result: be " minute position " or " co-bit ", or " overstepping one's bounds non-closing ", can't effectively monitor isolating switch motion overall process information; And in order to satisfy the unify needs of various protection control appliances of Department of Automation, auxiliary switch must provide nearly the position output contact of 8 pairs or more groups of numbers, cause the auxiliary switch failure rate to rise and volume larger; Since the situations such as process machine driving, auxiliary switch easily deform, become flexible, the frequent unmatched situation in position, Anomalies Caused or the accident that physical location and auxiliary switch occur in the isolating switch running.
The utility model content
The purpose of this utility model is to solve to judge physical location institute's Anomalies Caused of isolating switch or the problem of accident by the closure of auxiliary switch contact at present.
The utility model provides a kind of isolating switch to comprise the vertical-transmission bar for solving the problems of the technologies described above, and on the described vertical-transmission bar displacement transducer is installed, and is in transmission connection between displacement transducer and the vertical-transmission bar.
Described displacement transducer is socketed on the vertical-transmission bar of isolating switch, with vertical-transmission bar synchronous rotary.
Described displacement transducer is connected on the vertical-transmission bar by shaft coupling, with vertical-transmission bar synchronous rotary.
Described displacement transducer is the potentiometer type displacement transducer.
Described isolating switch also comprises intelligent processor, and the input of this intelligent processor links to each other with the output of displacement transducer, is used for the output signal of displacement transducer is converted to the angle signal of vertical-transmission bar.
Be provided with communication interface on the described intelligent processor, the positional information that is used for the isolating switch that will survey sends to host computer by Ethernet.
Also be connected with liquid crystal display on the described intelligent processor.
The beneficial effects of the utility model are: the vertical-transmission bar that displacement transducer is connected or directly is socketed in isolating switch by shaft coupling, with the drive link synchronous rotary, thereby output continually varying digital signal and can record motion process track and the movement velocity of isolating switch is for the life cycle management analysis management of isolating switch provides more basis for estimation.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further
The isolating switch mechanical realization variation that at present electric power system is used, but all can be abstract in adopting vertical-transmission bar rotation of motor-driven, again by what machine driving, the movable contact spring of final driving isolation switch is clamped the stationary contact bar, is judged to be " combined floodgate " position; When the motor reverse rotation, drive the motion of vertical-transmission bar, movable contact spring breaks away from the stationary contact bar, arrives an assigned address, is judged to be " separating brake " position.
As shown in Figure 1, isolating switch of the present utility model comprises casing 1, displacement transducer 2, vertical-transmission bar 3, gear reduction 4, motor 5, shaft coupling 6 and intelligent processor 7, displacement transducer 2 connects by shaft coupling 6 or directly is socketed on the vertical-transmission bar 3 of isolating switch, the output of displacement transducer links to each other with the input of intelligent processor, the output of intelligent processor links to each other with display, be provided with communication interface on the described intelligent processor, the positional information that is used for the isolating switch that will survey sends to host computer by Ethernet.
Its course of work is: displacement transducer and vertical-transmission bar synchronous rotary, intelligent processor continuous acquisition displacement transducer output signal, the vertical-transmission bar is to rotate back and forth clockwise or counterclockwise in a predetermined angle, this angle is 0 °～90 ° or 0 °～180 °, when supposing that isolating switch is in " co-bit ", the vertical-transmission bar is made as 0 °, when isolating switch is in " minute position " so, the vertical-transmission bar has rotated 90 ° or 180 °, be enclosed within simultaneously displacement transducer on the vertical-transmission bar and experience the rotation of drive link, synchronous output linearity signal, according to linear relationship, intelligent processor is converted to the displacement transducer output signal angle information of drive link, owing to be continuous signal, drive link is in any one angle all by Real-Time Monitoring, simultaneously can be in conjunction with rotational time, calculate the angular speed of drive link, intelligent processor also shows the angle information of vertical-transmission bar and the angular speed of drive link by LCD screen in real time, and intelligent processor is sent to ethernet network by its communication port with angle and the angular velocity information of vertical-transmission bar simultaneously.
