Technical background
The following electric distribution network electrical equipment of 35kV all is in the switch cubicle inside of sealing at present, under the operational environment and air oxidation effect of humidity, the electric connection contact resistance of equipment progressively increases, the surface generates heat thereupon, thereby make the vicious circle that causes connector temperature to raise, cause operational outfit fire or ground short circuit accident to occur at last.At this situation, it is that point for measuring temperature carries out thermometric to device junction that prior art adopts optical fiber grating temperature-measuring element (being fiber-optical grating temperature sensor), monitors by system.For fail safe and the integrity problem that solves the optical fiber grating temperature-measuring element, there is a kind of new type silicone rubber optical fiber insulator to come into operation.This insulator string is the outer surface suit sheet silicon rubber optical fiber insulator at one section optical fiber, the top fusion temp transducer of optical fiber, and tail end is provided with fiber connector.Silicon rubber optical fiber insulator string is made by shrinkage or pyrocondensation silicon rubber insulation material, and the several needs according to the operational outfit class of insulation of the sheet of optical fiber insulator string make up.The anti-power-frequency voltage of this insulator string, switching overvoltage, lightning overvoltage ability are stronger.
But, because nearly tens of the points for measuring temperature in the high-tension switch cabinet, each point for measuring temperature all needs an optical fiber grating temperature-measuring element monitoring, and each optical fiber grating temperature-measuring element is connected with signal transmission fiber again, each root optical fiber all needs an optical fiber insulator string to support, and therefore just exists fiber arrangement more random in a switch cubicle, a fairly large number of problem of optical fiber insulator string, this not only makes the temp measuring system cost increase, and security performance descends.
Summary of the invention
The purpose of this utility model is, use optical fiber insulator string a fairly large number of technical problem random at fiber arrangement in the present high-tension switch cabinet, and the insulation system of temperature measurement signal Transmission Fibers in a kind of high-tension switch cabinet is provided.
The technical solution of the utility model is: in the high-tension switch cabinet, each temperature measurement signal Transmission Fibers of each circuit breaker input or output homonymy is attached at circuit breaker homonymy high-tension line lead cloth not to be had, and each the signal transmission fiber together support after gathering is in same silicon rubber optical fiber insulator string.
The utility model can also be taked following technical measures:
Each signal transmission fiber at described silicon rubber optical fiber insulator string rear portion is laid in the bus duct of switch cubicle, is drawn.If there is not bus duct in the high-tension switch cabinet, signal transmission fiber can be laid, draw by bonding method on the high-tension switch cabinet wall.
Each optical fiber grating temperature-measuring element of described each circuit breaker input or output homonymy point for measuring temperature is in series or is arranged in parallel, the signal transmission fiber that connects each optical fiber grating temperature-measuring element is attached at circuit breaker homonymy high-tension line lead and lays, and is that shared signal transmission fiber is supported in same silicon rubber optical fiber insulator string after gathering.
The utility model has the advantages that: this insulation system is the boundary with the circuit breaker fracture, the equipotential temperature measurement signal Transmission Fibers of homonymy is directly laid on the homonymy high-tension line, and use same silicon rubber optical fiber insulator string, not only can satisfy the specification requirement of optical fiber insulation against ground and phase insulation, fiber arrangement is reasonable simultaneously, neat standard, the three-phase loop is at most only with 6 silicon rubber optical fiber insulator strings, solve existing high-tension switch cabinet signal transmission fiber more up hill and dale and arranged random problem, and can reduce the usage quantity of optical fiber insulator string significantly, reduce the installation cost of temp measuring system, and helped improving the fail safe and the reliability of optical fiber temperature measurement system operation.
