Description
Technical field
The utility model relates to the pick-up unit of the open and-shut mode of switch cubicle, is specially fiber grating distributed switch cabinet safety monitoring system.
Background technology
The high-tension switch cabinet of generating plant, transformer station is important electric equipment; so probably there is problem of aging in high-tension switch cabinet in During Process of Long-term Operation; technician needs to open detection often, to prevent from lacking internal components protection because cabinet is aging, causes fire etc.Technician repeatedly opens detection and occurs unavoidably forgetting closedown or closing unreal phenomenon, because inside switch cabinet running temperature is very high, extremely easily causes fire.Therefore need to detect and guarantee that switch cubicle pass is closed, for taking precautions against the key that this type of accident produces.Detection difficulty whether is closed little in high-tension switch cabinet, but switch cubicle quantity is a lot, rely on and manually go one by one to be confirmed whether to close, it is a thing of extremely losing time, and people is confirming it is the thing of danger close in the switch cubicle process of whether closing, and very likely electric shock event occurs.
Summary of the invention
The problem whether the utility model needs artificial detecting box door to close in order to the cabinet door solving high-tension switch cabinet after sensing, provides fiber grating distributed switch cabinet safety monitoring system.
The utility model adopts following technical scheme to realize: fiber grating distributed switch cabinet safety monitoring system, the fiber Bragg grating signal processor comprising switch cubicle folding fiber-optic grating sensor and be connected with main frame, switch cubicle folding fiber-optic grating sensor comprises the shell be fixed on switch cubicle inwall, the top of shell is fixed with litter cylinder, spring is provided with in litter cylinder, also sliding in litter cylinder, it is vertical to be provided with, through the litter of spring, the top of litter cylinder is stretched out on the top of litter, the bottom of litter is stretched out litter cylinder bottom and is deep in shell, the body of rod in litter cylinder of litter is also provided with pressure spring plate, the bottom terminal ends of litter is fixed with the first magnet, vertical base plate is also fixed with in shell, base plate plate face is fixed with reference to grating, base plate is also fixed with vertical shell fragment, the bottom of shell fragment and litter lays respectively at the both sides of base plate, the free end of shell fragment is fixed with the second magnet repelled mutually with the first magnet, the plate face of shell fragment is fixed with sensing grating, sensing grating is connected with fiber Bragg grating signal processor by optical cable.
When the top cover of switch cubicle is closed, litter presses down by top cover, stagger in the position of the first magnet of litter bottom terminal ends and the second magnet of shell fragment free end by pressure spring plate on litter mutually, the reflectance spectrum of the sensing grating on shell fragment and the reference grating on base plate overlaps, and sensing grating just can transmit switch cubicle shutdown signal to fiber Bragg grating signal processor; When the top cover of switch cubicle is opened, litter is upward sliding under spring restoring force effect, first magnet of litter bottom terminal ends is relative with the position of the second magnet, second magnet is repelled, sensing grating on shell fragment is separated with the reflectance spectrum of the reference grating on base plate, fiber Bragg grating signal processor does not receive switch cubicle shutdown signal, staff is by the open and-shut mode of main frame and observable switch cubicle, switch cubicle can be gone out whether be in closed condition by Real-Time Monitoring by this system like this, do not need manual confirmation, alleviate the pressure of staff.
Above-mentioned fiber grating distributed switch cabinet safety monitoring system, the plate face of base plate is fixed with the sleeve of top end opening, the bottom of litter extend in sleeve, fluctuates all the time in the bottom of litter in sleeve, ensure that the monitoring effect of system.
The utility model provides a kind of fiber grating distributed switch cabinet safety monitoring system, and by this system, staff by the open and-shut mode of main frame and observable switch cubicle, can not need manually to confirm one by one, alleviate the pressure of staff.
