Detailed description of the invention
Below in conjunction with Figure of description and concrete preferred embodiment, this utility model is further described, but the most therefore limits protection domain of the present utility model.
As it is shown in figure 1, the protective relaying device of hard pressing plate state is protected in a kind of automatic detection of this utility model, including at least one pressing plate detector unit 1, it is used for detecting the hard pressing plate of relay protection and puts into and exit state；The processing unit 2 being connected with pressing plate detector unit, for receiving the detection state value of pressing plate detector unit 1 and processing；The status display unit 3 being connected with processing unit, for showing the protection hard pressing plate state of relay.
In the present embodiment, pressing plate detector unit 1 is protected the voltage of hard pressing plate two ends by detection or protects hard pressing plate lower end voltage-to-ground judge the input of hard pressing plate and exit state.For function pressing plate, as shown in Figure 2 (A) shows, the magnitude of voltage between hard pressing plate two ends is protected in pressing plate detector unit 1 detection, if protecting no-voltage between hard pressing plate two ends, then showing to protect hard pressing plate to put into, otherwise showing to protect hard pressing plate to have dropped out.For output clamping, as shown in Fig. 2 (B), the voltage-to-ground of hard pressing plate lower end is protected in pressing plate detector unit 1 detection, if voltage-to-ground is 0, then shows to protect hard pressing plate not put into, otherwise, then shows to protect hard pressing plate to put into.In the present embodiment, pressing plate detector unit 1 obtains the state protecting hard pressing plate by detection voltage, and this status information is sent to processing unit 2, represents with 1, the hard pressing plate of protection, for exiting state, represents that the hard pressing plate of protection is for putting into state with 0.In Fig. 1; when the quantity of relay is 8; i.e. N=8; and the hard pressing plate of protection of relay 1 to relay 8 is input state; then processing unit 2 by pressing plate detector unit 1 detection obtain protect hard pressing plate status information be one 8 be all 1 sequence " 11111111 ", the protection hard pressing plate state of each corresponding relay.Protect the state of hard pressing plate for exiting such as relay 3 and relay 6, then the protection hard pressing plate state of correspondence is: " 11011011 ".
In the present embodiment, also include the data registration unit 4 being connected with processing unit 2, the protection hard pressing plate target-like state value for storage relay.Also including the control unit 5 being connected with processing unit 2, control unit 5 includes detecting button and setting button；Detection button starts primary relay for Artificial Control and protects hard pressing plate state-detection；Set button protection hard pressing plate target-like state value in the operational mode that protective relaying device is set and data registration unit 4.Also including the alarm unit 6 being connected with processing unit, when in the state hard pressing plate of relay protection being detected and data registration unit 4, the state of storage is inconsistent, alarm unit 6 sends alarm signal.In the present embodiment, preset a target-like state value protecting hard pressing plate by setting button as each relay of detection required for this device, this target-like state value be according to the input needed in relay actual motion with exit Determines.Such as 8 relays in the present embodiment; input according to actual needs is that hard pressing plate exits with the protection of relay 8 for relay 1, relay 2 with the state of exiting; the hard pressing plate of protection of other relay puts into, and the target-like state value the most now preset is: " 00111110 ".By the setting button of control unit 5, this target-like state value is stored to data registration unit 4, when needing the state of relay is detected, click on the detection button in control unit 5, control pressing plate detector unit 1 and detect the protection hard pressing plate state of each relay, obtain the actual status switch put into and exit state of the hard pressing plate of relay protection, this status switch is compared with the target-like state value of storage in data registration unit 4, if it is identical, then explanation detection is passed through, each relay protection hard pressing plate state meets the requirement of setting, the input having the hard pressing plate of protection of relay is otherwise described and exits status error, by alarm unit 6 signal an alert, staff is reminded to recover.Alarm unit 6 can be alarm lamp, or alarm buzzer etc..By setting button; the detection pattern of this utility model device can also be set as manual detection mode and autosensing mode; manual detection mode carries out the state-detection of the primary relay hard pressing plate of protection by artificial detection button of clicking on as required; the protection hard pressing plate state of relay can be detected by the predetermined detection cycle by autosensing mode according to setting.
When the detected relay quantity that this utility model device connects is more, the state of the hard pressing plate of each relay protection is the most directly perceived directly to use the sequence of values of 0 or 1 to show, convenient not, succinct.In order to further improve work efficiency, the state of the hard pressing plate of relay protection is made to show more directly perceived, succinctly.In the present embodiment, status display unit 3 is coding display unit, including 16 scale coding display units or 8 scale coding display units.The input that each relay is protected hard pressing plate carries out coded treatment with exiting status values sequence, and coding can use 16 systems or the coded system of 8 systems.Protecting the state of hard pressing plate for exiting such as relay 3 and relay 6, the sequence of values of the corresponding hard pressing plate state of protection is: " 11011011 ", and when using the coded system of 16 systems, then correspondence 16 hex value shown by status display unit 3 is: " DB ".When the coded system system not used for the quantity of relay represents the integral multiple of quantity, the present embodiment uses the mode of cover to supplement, and cover mode is optional high-order or low level mends the mode of " 0 ".Protect the state of hard pressing plate for exiting such as relay 3 and relay 6; the corresponding sequence of values protecting hard pressing plate state is: " 11011011 "; when using the coded system of 8 systems; the quantity of relay is 8; and the coded system system of 8 systems represents that quantity is 3; then the low of this sequence of values being carried out cover, the sequence of values after cover is: " 110110110 ", then correspondence 8 hex value shown by status display unit 3 is: " 666 ".It is of course also possible at high-order cover, or the cover of alternate manner.
Apparatus structure of the present utility model is simple, it is simple to I&M.By device of the present utility model, staff can obtain the input of the hard pressing plate of relay protection quickly, intuitively and exit status information, it is not necessary to check the state of the hard pressing plate of relay protection one by one；Meanwhile, by setting the target-like state value of the hard pressing plate of relay protection, it is also possible to automatically the state protecting hard pressing plate is the most correctly judged, when protecting hard pressing plate status error, send alarm and reminding staff and recover.By device of the present utility model, can be greatly improved staff and detect the work efficiency of relay protection hard pressing plate state, the labor intensity of reduction staff, and improve the accuracy of detection, reduce the error of manual detection, reliability is high.
Above-mentioned simply preferred embodiment of the present utility model, not makees any pro forma restriction to this utility model.Although this utility model is disclosed above with preferred embodiment, but it is not limited to this utility model.Therefore, every content without departing from technical solutions of the utility model, according to this utility model technical spirit to any simple modification made for any of the above embodiments, equivalent variations and modification, all should fall in the range of technical solutions of the utility model are protected.
