Abstract
The utility model provides an on-line acquisition device for the position information of a hand-operated switch, which is characterized in that an auxiliary switch (2), a hand-operated switch driving mechanism (1), a signal wire (3) and a measure and control device (4) are included, wherein the auxiliary switch (2) is mounted on the hand-operated switch and the connecting rod thereof is connected with the hand-operated switch driving mechanism (1); and the auxiliary switch is also connected with the measure and control device (4) through the signal wire (3). The utility model has the advantage that the state change of the auxiliary switch is driven by the actions (make and dead) of the hand-operated switch, and the position information of the hand-operated switch can be indirectly reflected through the state (make and dead) of the auxiliary switch, thereby realizing the on-line acquisition of the position information of the hand-operated switch.
Description
Technical field
The utility model relates to a kind of positional information harvester of manual disconnecting link, belong to the electric power project engineering field.
Background technology
In the existing technology, electronic disconnecting link is by supervisory control system collector positional information, but manually the positional information of disconnecting link never has online acquisition method effectively reliably.In existing anti-error system, the mode of employing electric blocking realizes the locking to the hand knife lock mostly, though this has realized the locking to the hand knife lock to a certain extent, but this mode reduces the intelligent degree of anti-error system greatly, simultaneously also can't be with the location status of manual disconnecting link barring condition as other relevant devices, make that anti-mis-logical is perfect inadequately, can not guarantee the fail safe of electric operation.Under the microcomputer anti-error pattern, adopt computer key and coding to lock the positional information that the mode of sign indicating number is gathered manual disconnecting link to the hand knife lock, though this a kind of mode has improved anti-error intelligent, but its information can not upgrade in time, have safety operation hidden danger, visible online acquisition hand knife gate position information has become the inevitable requirement of anti-error system development.
Summary of the invention
The utility model proposes a kind of positional information harvester of novel manual disconnecting link, its purpose is to overcome the above-mentioned defective of existing in prior technology, the positional information of not only having gathered manual disconnecting link is as one of criterion of anti-error system, but also the promptness that guarantee information is gathered has improved the fail safe and the reliability of operation greatly.
Technical solution of the present utility model: its structure is to be made of auxiliary switch, manual disconnecting link transmission mechanism, holding wire and measure and control device, wherein auxiliary switch is installed in manual disconnecting link place, the connecting rod of auxiliary switch links to each other with manual disconnecting link transmission mechanism, manually disconnecting link action (disconnecting or closure) will change the state of auxiliary switch, and auxiliary switch is connected with measure and control device by holding wire.
Advantage of the present utility model: drive the variation of auxiliary switch state by manual disconnecting link action (disconnecting or closure), the state (switching) of gathering auxiliary switch reflects the positional information of manual disconnecting link indirectly, thereby has realized the online collection of hand knife gate position information.
Description of drawings
Accompanying drawing 1 is a circuit structure schematic diagram of the present utility model.
Among the figure 1 is manual disconnecting link transmission mechanism, the 2nd, auxiliary switch, the 3rd, holding wire, the 4th, measure and control device.
Embodiment
The contrast accompanying drawing, its structure is to be made of auxiliary switch 2, manual disconnecting link transmission mechanism 1, holding wire 3 and measure and control device 4, wherein auxiliary switch 2 is installed in manual disconnecting link place, the connecting rod of auxiliary switch links to each other with manual disconnecting link transmission mechanism, manually disconnecting link action (disconnecting or closure) will change the state of auxiliary switch, and auxiliary switch is connected with measure and control device by holding wire.
Described auxiliary switch 2, when manual disconnecting link closure, manual disconnecting link acts on auxiliary switch by transmission mechanism makes the state of auxiliary switch be in closure state.
Described measure and control device is the closed and disconnected state that detects auxiliary switch.
The course of work:
The normality of auxiliary switch (being the state of button auxiliary switch when not being pressed) has two kinds, often open with normally closed, can select according to actual conditions, below selecting normality is that the Chang Kaifang formula describes the course of work, and manual disconnecting link was for opening when defined auxiliary switch disconnection in the system this moment; Manual disconnecting link was closed when auxiliary switch was closed.
The separating brake process:
Before the separating brake, because manual disconnecting link closure, manual disconnecting link acts on auxiliary switch by transmission mechanism makes the state of auxiliary switch be in closure state, and measure and control device detects the closure state of auxiliary switch, and this moment, system thought that the state of auxiliary switch is closed; During operating personnel's sub-switching operation, the moving transmission mechanism of the hand knife strap of the brake changes the location status of auxiliary switch, and the state of auxiliary switch is changed into off-state, and measure and control device detects the off-state of auxiliary switch, and this moment, system thought that the state of manual disconnecting link is for opening.As seen, be reflected to the state variation real-time online of sub-switching operation process by auxiliary switch background system.
Making process:
Before the combined floodgate, auxiliary switch be in free state, the state of auxiliary switch is in off-state, measure and control device detects the off-state of auxiliary switch, this moment, system thought that the state of manual disconnecting link is an off-state; During operating personnel's closing operation, the moving transmission mechanism of the hand knife strap of the brake changes the state of auxiliary switch, and auxiliary switch is changed into closure state, and measure and control device detects the closure state of auxiliary switch, and this moment, system thought that also the state of manual disconnecting link is closure.As seen, be reflected to the state variation real-time online of closing operation process by auxiliary switch background system.
