Abstract
The utility model relates to a remote reset controller for relay protection equipment, which can quickly and accurately achieve the reset of the relay protection equipment, wherein the remote rest controller comprises controllers used for controlling the switch on/off of the relay protection equipment; the controllers comprise execution output units and communication units; the communication units are connected with control panels via signal lines; the control panels are connected with a server via an exchanger; each control panel has an exclusive number or an invariable network address; and the execution output units adopt remote control switches. The utility model has the advantages that the reset of the relay protection equipment can be quickly and accurately executed, so as to greatly improve the working efficiency of staff in a transformer substation, lower accident rate of a transmission line and reduce disastrous economic loss caused by power failure.
Description
[technical field]
The utility model relates to a kind of protective relaying device remote reset controller, remote reset protective relaying device quickly and accurately.
[background technology]
Protective relaying device, English name: relay protection equipment, definition: one or more protection components (like relay) and logic element are fitted in together and accomplish the device of a certain specific defencive function in the electric power system on request.Protective relaying device generally by measure comparing element (or several transducers such as electric current, voltage transformer), the logic determines element (is made up of 4 current relays; Two is fast tripping protection, and two is overcurrent protection in addition) and carry out output element (switching winding of sound and optic signal relay or circuit breaker operation mechanism) formation.
When fault has taken place and has jeopardized safe operation of power system in the force device in the electric power system (like generator, circuit etc.) or electric power system itself; Can in time send warning signal to the operation operator on duty; Perhaps directly send trip signal to stop these incident development, reduce influence the power system security power supply to the circuit breaker of being controlled.(as: single-phase earthing, light transformer, heavy Gas Signal, transformer temperature rise high excessively).
At present, the situation that crashes because of the undesirable device that causes unusually with the protective relaying device software and hardware of protective relaying device running environment happens occasionally.The staff is often away from protective relaying device, and manual reset needs long time, and when the power equipment of unprotect operation broke down, protective relaying device can not in time excise fault, thus the expansion that causes the accident.The protective relaying device that resets quickly and accurately is necessary very much.
[utility model content]
For the protective relaying device that can reset in time, exactly; The utility model provides a kind of protective relaying device remote reset controller; This controller protective relaying device that can not only reset quickly and accurately, and can reduce the risk that crashes and cause electric power accident to enlarge because of protective relaying device effectively.
The technical scheme of the utility model is: protective relaying device remote reset controller; Comprise the controller that is used to control the protective relaying device on/off; This controller comprises carries out output unit and communication unit; This communication unit is connected with control board through holding wire, and said control board is connected with server through the network switch.
As the further improvement of such scheme, said control board has unique number or fixed network address.
This controller principle is: server is mounted on the control board in each transformer station through the network switch, and control board is mounted on the controller in the protective relaying device screen cabinet through netting twine, the power supply of controller control protective relaying device.When the operations staff receives alarm signal, when finding that protective relaying device is in the deadlock state, import the instruction of this protective relaying device that resets; Reset instruction is transmitted through the network to the control board that is installed in the transformer station, and control board is resolved control command, sends reset signal through communication unit to controller; After controller receives reset instruction; By carrying out the device power supply that output unit breaks off protective relaying device, recover the protective relaying device power supply after a while automatically, accomplish resetting of protective relaying device.
The advantage of the utility model is: remote reset protective relaying device quickly and accurately, improved the personnel's of transformer station operating efficiency greatly, and reduced the incidence of transmission line accident simultaneously, reduce the heavy economic losses that has a power failure and bring.
[description of drawings]
Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings.
Fig. 1 is the equipment composition diagram of the utility model.
Among the figure: 1. controller, 2. control board, 3. Ethernet, 4. switch, 5. server.
[embodiment]
Referring to Fig. 1; Protective relaying device remote reset controller; Comprise the controller 1 that is used to control the protective relaying device on/off; Controller 1 comprises carries out output unit (generally adopting remote control switch) and communication unit (communication module), and this communication unit is connected with control board 2 through Ethernet 3, and control board 2 is connected with server 1 through the network switch 4.Every control board 2 has independent IP address or unique number, is convenient to staff's identification.
When the operations staff receives alarm signal; When finding that protective relaying device is in the deadlock state, import the instruction of this protective relaying device that resets, reset instruction is transmitted through the network to the control board 2 that is installed in the transformer station; Control board 2 is resolved control command; Send reset signal through communication unit (communication module) to controller 1, after controller 1 receives reset instruction, by carrying out the device power supply that output unit breaks off protective relaying device; Automatically recover the protective relaying device power supply after a while, accomplish resetting of protective relaying device.
Although illustrated and described the embodiment of the utility model; For those of ordinary skill in the art; Be appreciated that under the situation of principle that does not break away from the utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment, the scope of the utility model is limited accompanying claims and equivalent thereof.
Claims (3)
1. protective relaying device remote reset controller; It is characterized in that: this controller comprises the controller that is used to control the protective relaying device on/off; This controller comprises carries out output unit and communication unit; This communication unit is connected with control board through holding wire, and said control board is connected with server through the network switch.
2. according to the said protective relaying device remote reset of claim 1 controller, it is characterized in that: said control board has unique number or fixed network address.
