Description
Technical field:
The utility model relates to a kind of security protection system for switch cubicle.
Background technology:
In power system, often all can there is the phenomenon that switch cubicle is burnt, more seriously, all can have several electricity every year
Power engineer or electrician are injured, and how preferably to ensure personal safety, it is ensured that the reliable and stable operation of electric power system is to pass
Important.The reason that analysis is broken down, substantially divide three below aspect: arc short-circuit, current overload and temperature are too high.At this
Among, arc short-circuit is fault the most serious in power distribution network, especially in the situation within middle-low voltage switch cabinet, due to short circuit electricity
Stream do not reached stream, quick-break setting valve and can not cause tripping operation cut-out action.During in addition, there is lonely light fault in switch cubicle, if
Cannot get removing in time, develop into middle pressure bus-bar fault, its harm is very serious, as power plant electricity consumption disintegrate, responsible consumer stops
More electricity etc., more serious cause organizing switch cubicle and burn simultaneously.Present stage does not has the full side for switch cubicle for the effective device
Face is protected, and i.e. carries out comprehensive detection to arc short-circuit, current overload and running temperature are too high.
Utility model content:
The utility model, in order to make up the deficiencies in the prior art, provides a kind of security protection system for switch cubicle,
Its system configuration is reasonable, and automatic control alarm is quick on the draw, and breakdown judge is accurate, can be wirelessly transferred, carry out power distribution cabinet
Full protection, solves problems of the prior art.
The utility model be the technical scheme is that by the above-mentioned technical problem of solution
A kind of security protection system for switch cubicle, including main controller and the safety device being located in switch cubicle,
Described safety device includes that a central processing unit, central processing unit and a data link are connected, data link and master
Control device passes through wired data transfer or Wireless Data Transmission is connected, and central processing unit is supervised in being located at switch cubicle by wire respectively
If some current detector dry temperature sensors that location is put are connected with some lonely optical sensors, central processing unit is by a jump
Lock relay lock total with switch cubicle is connected.
Preferably, being additionally provided with independent current source in safety device, independent current source passes through wire and central processing unit phase
Even.
Preferably, being additionally provided with display control panel at safety device outer surface, display control panel passes through wire
It is connected with central processing unit.
Preferably, display control panel is provided with alarm display lamp.
The utility model uses such scheme, and system configuration rationally, uses one to drag many modes, i.e. one main controller control
The mode of multiple safety devices being located in switch cubicle；Display control panel is provided with alarm lamp and is conducive to site examining and repairing
Personnel quickly determine type and the position of fault；Owing to arc short-circuit, temperature, electric current are detected by different detectors, anti-
Protecting comprehensively, information provides more accurate, can enter line position positioning during breakdown judge, and is provided with data link and can carry out wireless
Transmission and manipulation.
Brief description:
Fig. 1 is structural schematic block diagram of the present utility model.
Detailed description of the invention:
For the technical characterstic of this programme can be clearly described, below by detailed description of the invention, and combine its accompanying drawing, to this reality
It is described in detail with novel.
As it is shown in figure 1, a kind of security protection system for switch cubicle, including main controller and the safety being located in switch cubicle
Protector, described safety device includes that a central processing unit, central processing unit and a data link are connected, and data pass
Defeated device is connected by wired data transfer or Wireless Data Transmission with main controller, central processing unit respectively by wire be located at out
If in closing cabinet, some current detector dry temperature sensors of monitoring position are connected with some lonely optical sensors, central processing unit
It is connected by the total lock of a tripping relay and switch cubicle.
Being additionally provided with independent current source in safety device, independent current source is connected with central processing unit by wire.Independent
Power supply is powered and be ensure that under some state of emergency, and this safety device can continue to work, and provides accurate letter on the other hand
Breath.
Being additionally provided with display control panel at safety device outer surface, display control panel passes through wire and centre
Reason device is connected.When breaking down, display control panel can provide switch cubicle malfunction intuitively for field service personnel
Display.Display control panel is provided with alarm display lamp.Control panel is provided with alarm lamp and is conducive to field service personnel fast
Speed determines type and the position of fault.
During mounting arrangement, if first some current detector dry temperature sensors and some lonely optical sensors being put respectively
In desired location in switch cubicle.Current detector is placed on the circuit that main line etc. may overload, and temperature sensor is placed in
Circuit or the intensive position of joint, arc photosensor is placed in the position that may produce arc light.Then each sensor and central authorities
Processor be connected, central processing unit is connected with main controller by the data link which is provided with, and pass through tripping relay and
The total lock of switch cubicle is connected.During use, if occurring abnormal conditions in switch cubicle, either temperature, electric current or arc light occur abnormal
State, first passes through the tripping operation of tripping relay proximity switch cabinet total lock.These abnormality data all can be passed by data simultaneously
Defeated device is delivered in main controller, can arrange warning device on main controller so that it is can carry out automatic control alarm, reminds monitoring
Personnel quickly carry out relevant action.Monitoring personnel can provide instruction for Field Force, rushes to repair.When Field Force is former to having
When the safety cabinet of barrier is repaired, fault state can be established further by the alarm display lamp on display control panel.Then carry out
Upkeep operation.Arranging alarm threshold value additionally by main controller or display control panel, equilibrium testing agency is quick on the draw and misses
Report phenomenon.And by sensor is numbered, and can carry out being accurately positioned by numbering and further reduce on-the-spot people
The working strength of member.Using this kind of mode, when a failure occurs it, monitoring personnel are immediately available for determining abort situation and failure classes
Type.And discrete this kind of mode that be set to of the utility model current detector, temperature sensor and arc photosensor provides base
Plinth.
Above-mentioned detailed description of the invention cannot function as the restriction to the utility model protection domain, for the skill of the art
For art personnel, any alternate modification or the conversion of being made the utility model embodiment all fall within guarantor of the present utility model
