Abstract
The utility model relates to a misoperation-prevention locking device for dispatch remote control operation is characterized in that the misoperation-prevention locking device includes a controller and at least a relay switch controlled by the controller; the relay switch comprises an installation shell; a circuit board is arranged in the shell; the circuit board is provided with an MCU as well as a communication interface circuit and a driving circuit which are connected with the MCU, wherein the driving circuit is used for driving a coil switch. With the misoperation-prevention locking device for dispatch remote control operation of the utility model adopted, remote operation on a plurality of electric devices in a substation can be realized, and damage to the electric devices or related devices caused by the operation of non-professionals can be avoided.
Description
Technical field
The utility model belongs to electrical equipment remote control anti-misoperation technical field in electric power system, relate in particular to a kind of dispatching remote control operation anti-misoperation locking device, refer in particular on a kind of equipment that is applied in the electronic controls of needs such as transformer station, power plant, petrochemical industry, metallurgy, coal, realize the remote operation to electrical equipment by this device.
Background technology
Along with the popularization of " regulating and controlling integrated " operation and management mode and the construction of a large amount of unattended operation transformer stations, remote control operation is more and more, because of the mistake remote control that operations staff selects wrong equipment to cause, progressively rises to the subject matter of current electric misoperation.
" the preventing electric misoperation safety management regulation " of promulgating in State Grid Corporation in 2006 October prevents to transformer station explicitly pointing out in the requirement of electric misoperation that " 4.1.8---the remote control operation of-main website, local operation are realized " five is anti-" forced blocking function.Therefore, romote controlled locking device aims at the forced blocking of solution straighforward operation and researches and develops.
Utility model content
The purpose of this utility model is to provide a kind of dispatching remote control operation anti-misoperation locking device, realizes electrical equipment remote operation in transformer station, avoids layman to operate and causes the damage of electrical equipment or the damage of associated device.
The utility model adopts following scheme to realize: a kind of dispatching remote control operation anti-misoperation locking device, is characterized in that: comprise a controller and be controlled by least one relay switch of this controller; Described relay switch comprises a holder housing, in described holder housing, is provided with circuit board, the communication interface circuit and the drive circuit that on described circuit board, are provided with MCU and are connected with this MCU, and described drive circuit is in order to drive coil switch.
In the utility model one embodiment, between described controller and relay switch, communicated to connect by monobus.
In the utility model one embodiment, described coil switch is serially connected in the control loop of electrical equipment, and is open mode under conventional state.
A kind of dispatching remote control operation anti-misoperation locking device of the present utility model; can realize the remote operation of electrical equipment; protect operating personnel's personal safety; simultaneously; realize the control to multiple electrical equipments by master controller, improved the anti-misoperation judgement of electrical equipment, reduced the damage that equipment operating causes because of artificial origin; guarantee the safe operation of whole substation equipment, there is very high economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is the utility model hardware structure schematic diagram.
Fig. 2 is the concrete schematic block circuit diagram of the utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.
As depicted in figs. 1 and 2, the present embodiment provides a kind of dispatching remote control operation anti-misoperation locking device, it is characterized in that: comprise a controller 1 and be controlled by least one relay switch 2 of this controller 1; Described relay switch 2 comprises a holder housing 3, in described holder housing, is provided with circuit board, the communication interface circuit and the drive circuit 5 that on described circuit board, are provided with MCU4 and are connected with this MCU, and described drive circuit 5 is in order to drive coil switch 6.
Preferably, in the present embodiment, between described controller and relay switch, communicated to connect by monobus.Monobus communication can guarantee, into relay switch power supply, can realize again the transmission of communication instruction.Please continue referring to Fig. 2, coil switch 6 described in figure is serially connected in the control loop of electrical equipment 7, and is open mode under conventional state.
The utility model is realized the control to multiple relay switches by a controller, and relay switch does not need to arrange in addition power supply, and each relay possesses independently processor, if being set, different programs can also there is different control models, simple in structure, expansibility is good.
The above embodiment has only expressed execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of 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.Therefore, the protection range of the utility model patent should be as the criterion with claims.
