Background technology
Due to the many merits that GIS has, GIS device manufacture and correlation technique develop rapidly, and gas-insulated transmission line (GIL) is also paid close attention to more and more widely.GIL because of its reliability high, transmission capacity is large, and electric energy loss is little, is widely used gradually.
Because gas-insulated transmission line is very long, multiple inflation unit is generally divided into during design, each inflation unit is made up of multiple manufacturing cell, and be equipped with telescopic joint (corrugated tube), in the ideal situation, generally need ensure that it can only move axially at normal operation period and because of stressed, radial displacement not occur when mounted.But the impacts such as environment temperature change, processing alignment error, settlement of foundation and earthquake are subject to due to GIL; often can there is axis and transversal displacement; in order to monitor the GIL deformation that bus causes by the various factors such as the temperature difference and installation affects; improve the reliability of GIL safe operation; need to record its axis and transversal displacement; but general axis is easily intuitively found out usually to displacement deformation; and radial displacement is not easy intuitively to find out, therefore mostly adopts at present and in position radial displacement monitoring device is installed.
At present, the radial displacement monitoring device that existing GIL comprises bus in GIS string is fairly simple, usually arranges a pointer perpendicular to ground, and then the scale corresponded on bus observes the radial deformation of bus.This device can observe that larger displacement is out of shape to a certain extent.But this method has certain limitation, first pointer itself is easily subject to the impact of extraneous factor and bends, thus the accuracy that impact is measured; In addition, this device can not carry out Real-Time Monitoring to the distortion of bus, and needs to monitor more power station, and measurement mechanism is also many, brings great workload to the staff patrolled and examined.
Utility model content
The purpose of this utility model is to provide a kind of GIL radial displacement monitoring device, to ensure the accuracy that GIL radial displacement is measured.
In order to realize above object, the technical scheme that the utility model adopts is: a kind of GIL radial displacement monitoring device, comprise and being fixedly mounted on GIL cylindrical shell, for measuring the Angle Measurement Module of cylindrical shell and surface level angle, the signal output part of described Angle Measurement Module is connected with the signal input part of control module, and described control module is used for being converted into radial displacement signal by measuring the angle signal obtained and exporting.
This device also comprises the radial deformation display screen that the angle for angles of display signal be connected with control module changes display screen and shows radial displacement signal.
This device also comprises and carries out for the numerical range residing for radial displacement signal the GIL running LED that indicates.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
Be illustrated in figure 1 the perfect condition in bus installation and operation, namely do not produce radial displacement, but because alignment error, equipment processing and the existence of foozle and cylindrical shell are by the impact of some external force in reality, all can produce corresponding radial displacement.
Be illustrated in figure 2 issuable deformation in GIL operational process, corresponding will produce angle and radial displacement, GIL radial displacement monitoring device of the present utility model is exactly the angle beta by measuring cylindrical shell and surface level, then calculates the radial displacement a of cylindrical shell according to this angle and barrel lenght L.
As shown in Figure 3, measurement mechanism 1 for measuring cylindrical shell 3 and surface level angle in the present embodiment is arranged at the upper horizontal position of joint flange 7 between cylindrical shell and corrugated tube 2, during calculating, the radial displacement that leg-of-mutton funtcional relationship calculates cylindrical shell is formed according to cylindrical shell, surface level and cylindrical shell radial displacement, namely a=L*tg β, L are the horizontal range between the fixed support 4 of measurement mechanism mounting points and GIL.
In addition, the radial-deformation that can be born by GIL by computational analysis divides safety, early warning and the numerical range corresponding to danger, and associated by the pilot lamp of numerical range to the corresponding running status that measurement mechanism is arranged, then judge that the scope residing for radial displacement of the measurement point calculated by angle value lights corresponding pilot lamp.
As Fig. 4 ~ Figure 5 shows that GIL radial displacement monitoring device structure of the present utility model and schematic diagram, as seen from the figure, this device comprises and being fixedly mounted on GIL cylindrical shell, for measuring the Angle Measurement Module of cylindrical shell and surface level angle, the signal output part of Angle Measurement Module is connected with the signal input part of control module, and control module is used for being converted into radial displacement signal by measuring the angle signal obtained and exporting.
In addition, for ease of observing and using, this device also comprises the radial deformation display screen 92 that the angle for angles of display signal be connected with control module changes display screen 91 and shows radial displacement signal, and the GIL running LED that indicates is carried out for the numerical range residing for radial displacement signal, comprise normal relay indicating light 81, early warning pilot lamp 82 and risk indicating lamp 83; Also comprise the action buttons such as reset 10.
This device is packaged together by more than a housing corresponding functional module, is arranged on the fixed position of GIL, extraneous factor can being avoided monitoring the impact caused, being provided with the Real-Time Monitoring of data and the double insurance effect of signal designation simultaneously.
As shown in Figure 6, principle of work and the process of the utility model monitoring device are as follows: GIL displacement monitor is arranged on GIL fixed position, after calibration display screen 91,92 show respectively bus and horizontal angle and bus diametrically deflection, now normally relay indicating light 81 is bright.Along with impacts such as extraneous temperature rise and settlement of foundation, its radial-deformation will change, angle signal is delivered to angle change display screen 91 and shows by Angle Measurement Module, by writing corresponding program, the data of display screen 2 are changed into actual GIL radial deformation data by control module 3, its numerical value will show in real time at display screen 92.Simultaneously arrange control module 3 according to the vertical scope of radial deformation of the safety of setting, early warning and danger, if GIL radial-deformation increases to early warning range in operational process, then normal relay indicating light 81 goes out, and early-warning lamp 82 is bright; When there is serious radial deformation, risk indicating lamp 83 is bright, and GIL distortion now, beyond the safe radial deformation scope of the original design of GIL, takes appropriate measures according to actual conditions, thus ensures that GIL is safe and reliable to operation.
