Description
Technical field
This utility model is related to a kind of protective relaying device of plug and play.
Background technology
In Operation of Electric Systems, protective relaying device fault happens occasionally, and now typically requires interruption maintenance, maintenance or more
Change this protective relaying device, before recovery, need to carry out debugging and the verification experimental verification protection device integrity of complexity.How soon quick-recovery
Power supply is that one important and the problem of practicality.
Content of the invention
The purpose of this utility model be to provide a kind of when scene protection plant failure, can soon quick-recovery to power train
The protective relaying device of the plug and play of blanket insurance shield.
Technical solution of the present utility model is：
A kind of protective relaying device of plug and play, is characterized in that：Connect socket including relay protection, relay protection connects
Socket connects plug cooperation with corresponding relay protection；Described relay protection connects socket and includes A, B, C, D, E, F, G, H, I nine
Individual part；Wherein A, B, C, D, E part is the general connecting hole of 30 pins, and power supply, signal, operation, protection breaker tripping and closing, link it
Its equipment, redundancy back-up circuit connect；F part is 28 pin AC current-voltage loops, realizes after current loop contact pin is extracted certainly
Dynamic short circuit function；G part is 8 hole fiber position；H part is 6 hole fiber position and 2 road Std. Mesh；I part is 6 road signs
Quasi- mesh.
This utility model is rational in infrastructure, when scene protection plant failure, in continuing of the plug and play to powered stand-by heat
After the definite value of electrical protective device is set or is checked, can the protection to power system for the quick-recovery soon.This device is also applied for
Moving electric power power supply facilities.
General relay protection is set and connects socket, plug pair, general relay protection connects socket and is fixedly installed in scene, real
The company in the loop such as now standby to optical fiber, power supply, current/voltage, signal, operation, protection breaker tripping and closing, linkage miscellaneous equipment, redundancy
Connect, general relay protection connects the protective relaying device that plug is connected to plug and play；Protective relaying device other parts and biography
System protective relaying device is identical；General relay protection is connected socket and is realized in plug by the elastic connecting device of current loop
In journey, current loop is not opened a way；Relay protection connects plug and socket and has self-checking function, can judge self-operating situation, connection
Reliability；Standby plug and play protective relaying device can realize cold standby or stand-by heat.
Brief description
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of one embodiment of this utility model.
Fig. 2 is relay protection connection socket structure schematic diagram.
Specific embodiment
A kind of protective relaying device of plug and play, connects socket 1 including relay protection, and relay protection connects socket and phase
The relay protection answered connects plug 2 and coordinates；Described relay protection connects socket and includes nine parts of A, B, C, D, E, F, G, H, I；
Wherein A, B, C, D, E part is the general connecting hole of 30 pins, and power supply, signal, operation, protection breaker tripping and closing, linkage miscellaneous equipment,
Redundancy back-up circuit connects；F part is 28 pin AC current-voltage loops, realizes current loop contact pin and extracts rear automatic short circuit work(
Energy；G part is 8 hole fiber position；H part is 6 hole fiber position and 2 road Std. Mesh；I part is 6 road Std. Mesh.
Std. Mesh is replaced by 485 mouthfuls or RS232 mouth.
It is being connected by formula of no transition joint that general relay protection connects G, H, I section sets in socket, is directly connected to
Connect at plug in general relay protection, lead directly to protection device, reduce optical fiber attenuation.
General relay protection connects plug and the loop function for monitoring reality connecting through protective relaying device being connected socket
Existing integrity monitors.
