Description
Technical field
The utility model belongs to Automation of Electric Systems control technology field, is specifically related to a kind of protective relaying device.
Background technology
At present, the basic function of domestic and international various protective relaying device products is identical: timely cut-off breaker is not damaged and is encroached on protection equipment property, personnel etc. when power equipment breaks down.
Between the tripping operation of protective relaying device tripping operation, closing relay contact and circuit breaker, closing coil, must have be convenient to operation, visual obvious electric cut-off point, be commonly referred to as hard pressing plate (also claiming brace).When protected device fails, protective relaying device disconnects primary cut-out by the hard pressing plate that trips, and to guarantee system safety, hard pressing plate etc. the various hard pressing plate principles of closing a floodgate are probably like this.When electric equipment overhauls, manually hard pressing plate is disconnected, cause visual electric cut-off point, the person while guaranteeing to overhaul and device security; Overhaul complete after, should drop into pressing plate, the equipment investments such as protective relaying device operations.Because the opening of existing non intelligent pressing plate, disconnected position can't transfer to protective device; although on-the-spot frequent generation protective device correct operation in service; but because hard pressing plate input is incorrect, make primary cut-out tripping or malfunction, thereby cause serious security incident.
Summary of the invention
For moving back mistake because of the hard pressing plate throwing of breaker tripping and closing, the protective relaying device that overcomes the prior art existence causes the switch failure problem; the utility model provides a kind of protective relaying device; by handle trip, the throwing, retreating positional information of the hard pressing plate such as combined floodgate reads in protective relaying device; make protective relaying device put real time information by judging that hard pressing plate on its jump, closing loop is thrown to give up the throne; send the sound and light alarm signal; stop security incident; accomplished the science prevention before accident, the power system security accident that the problem thus of having solved causes.
the purpose of this utility model is achieved through the following technical solutions: a kind of protective relaying device, comprise housing, the relaying protection main circuit, hard pressing plate management circuit and hard pressing plate, described hard pressing plate comprises the hard pressing plate of tripping operation and the hard pressing plate that closes a floodgate, described hard pressing plate management circuit is connected by the M08 bus with described hard pressing plate, the panel of described housing is provided with an input that can show the hard pressing plate of described tripping operation, exit the LED lamp of position, the inside of described housing is provided with a sounding component and one and records described hard pressing plate and throw the recording element of the historical data of moving back, the input of described hard pressing plate, exiting position is read in described relaying protection main circuit by described M08 bus.
Preferably, described hard pressing plate management circuit is provided with four-wire interface.
Described four-wire interface is connected with hard pressing plate by M08 bus or RS485 bus.
compared with prior art, the utlity model has following beneficial effect: the utility model trips by handle, the throwing of the hard pressing plate such as combined floodgate, the information of putting of giving up the throne is read in protective relaying device, protective relaying device is thrown by judging the hard pressing plate on its closing loop, give up the throne the information of putting and make the logic judgement, realize sound and light of alarm, stop security incident, solve the safety problem of power equipment operation, simultaneously, the hard pressing plate of device internal record is thrown the historical data of moving back, be convenient to the throwing of the hard pressing plate of accident post analysis, move back process, can avoid thus on-the-spot because the incorrect security incident that causes is moved back in hard pressing plate throwing, also solved the difficult problem in on-the-spot operational management.The utility model simple installation, stable and reliable for performance, avoided, because of accidents such as equipment that safety problem causes, the person, being convenient to on-the-spot industrialization Installation and Debugging.
The accompanying drawing explanation
By reading the detailed description of non-limiting example being done with reference to the following drawings, it is more obvious that other features, objects and advantages of the present utility model will become:
Fig. 1 is structural representation of the present utility model.
In figure, 1 is the hard pressing plate of tripping operation, and 2 are the hard pressing plate that closes a floodgate, and 3 is the M08 interface, and 4 is hard pressing plate management circuit, and 5 are the relaying protection main circuit, and 6 is trip pressing plate position LED lamp, and 7 is sounding component, and 8 are the protection housing.
Embodiment
Below in conjunction with specific embodiment, the utility model is elaborated.Following examples will help those skilled in the art further to understand the utility model, but not limit in any form the utility model.It should be pointed out that to those skilled in the art, without departing from the concept of the premise utility, can also make some distortion and improvement.These all belong to protection range of the present utility model.
a kind of protective relaying device as shown in Figure 1, comprise relaying protection main circuit 5, hard pressing plate management circuit 4, protection housing 8, described hard pressing plate comprises the hard pressing plate 1 of tripping operation and the hard pressing plate 2 that closes a floodgate, described hard pressing plate management circuit 4 is connected by the M08 bus with described hard pressing plate, the outer surface of described housing 8 is provided with an input that can directly show described hard pressing plate, exit the trip pressing plate position LED lamp 6 of position, the inside of described housing is provided with a sounding component 7, the input of described hard pressing plate, exiting position is read in described relaying protection main circuit 5 by described M08 interface, described M08 bus interface 3 is four-wire interface, described four-wire interface is connected the hard pressing plate of hard pressing plate management circuit and intelligence by M08 bus or RS485.
When red when the hard pressing plate of tripping operation drops into, green light is bright when the hard pressing plate of tripping operation exits, double-colored flicker in turn when hard pressing plate contact is unreliable; This hard pressing plate and other hard pressing plate can be on protective relaying device LCD or by the inquiry of integrated system backstage.When protective relaying device judgement protection circuit has electric current; and the hard pressing plate that trips does not drop into; the protective device sound and light alarm; the event report explicit message of protective device " circuit has stream; trip pressing plate does not drop into "; the backstage integrated system also there will be relevant warning message, the power system security accident that the problem thus of having solved causes.When hard pressing plate was in the virtual connection state position, this protective device also can send the sound and light alarm signal.The utility model has been accomplished the science prevention before accident, and the technical scheme that while the utility model provides has also been filled up the technological gap in domestic and international this field.
Above specific embodiment of the utility model is described.It will be appreciated that, the utility model is not limited to above-mentioned specific implementations, and those skilled in the art can make various distortion or modification within the scope of the claims, and this does not affect flesh and blood of the present utility model.
