Detailed ways

first embodiment

Please refer to FIG. 1. FIG. 1 shows a schematic diagram of the method for evaluating the state of a bellows provided by the first embodiment of the present application, which specifically includes the following steps:

Step S110, acquiring the number of attention values in the four-dimensional detection quantities of the bellows.

Due to the deformation of the GIS shell due to seasonal changes, the four dimensions of the bellows are radially deformed, so that the variables in the four dimensions can be detected for data analysis;

The dimension when the standard dimension floats within the first error range is taken as the attention value, wherein neither the standard dimension nor the specific value of the first error range should be construed as a limitation of the present application.

Specifically, for example, for a 330kV Xikai factory corrugated pipe, the standard size is 400mm, and the first error range is 400mm±8mm to 400mm±10mm; for a 330kV Xindongbei manufacturer’s corrugated pipe, the standard size is 450mm, and the first error range is 450mm±10mm 30mm to 450mm±40mm; for 750kV flat-height factory corrugated pipe, the standard size is 2000mm, and the first error range is 2000mm±25mm to 2000mm±35mm.

Step S120: Obtain the number of warning values in the four-dimensional detection quantities of the bellows.

The dimension when the standard dimension floats within the second error range is used as a warning value, wherein neither the standard dimension nor the specific reference to the second error range should be construed as a limitation of the present application.

Specifically, for example, for a 330kV Xikai factory corrugated pipe, the standard size is 400mm, and the second error range is over 400mm±10mm; for a 330kV Xindongbei manufacturer’s corrugated pipe, the standard size is 450mm, and the second error range is over 450mm±40mm; For 750kV flat-height factory corrugated pipes, the standard size is 2000mm, and the second error range is more than 2000mm±35mm.

Step S130, obtaining the absolute value of the difference between the length of the sun-facing surface of the corrugated tube and the length of the back-facing surface of the corrugated tube.

Due to the obvious effect of sunlight on the temperature of the GIS shell, the extension of the GIS shell is higher than that of the back side on the surface that receives more sunlight, so that the compression of the sun side of the bellows is higher than that of the back side of the bellows, that is, The length of the back side of the corrugated pipe is longer than the length of the sun side of the corrugated pipe, and then the difference between the length of the sun side of the corrugated pipe and the back side of the corrugated pipe can be obtained.

Step S140: Obtain the score of the bellows according to the number of the attention values, the number of warning values, the absolute value, and the first preset relationship among the above three.

The first preset relationship is T=100-X*2-Y*5-Z, the score T of the bellows can be obtained according to the above formula, where X is the attention in the four-dimensional detection quantities of the bellows The number of values, Y is the number of warning values in the four-dimensional detection of the bellows, Z is the absolute value of the difference between the length of the sun-facing side of the bellows and the length of the backside of the bellows.

Obtain the scoring results of the bellows according to the first preset relationship, and conduct targeted investigations on the bellows in the attention, abnormal and serious states, which can effectively classify the working conditions of the bellows in the station, formulate maintenance strategies respectively, and improve work efficiency. and targeted monitoring.

For example: if the first value is 70, according to the formula T=100-X*2-Y*5-Z in step S140, the obtained score T is 77, then it can be determined that the bellows is in a normal state; if according to step S150 In the formula T=100-X*2-Y*5-Z, the obtained score T is 66, then proceed to the next step S170.

In step S160, it is judged whether the score of the bellows is greater than the second value; if so, it is judged that the bellows is in the attention state; if not, step S170 is performed.

For example: if the second value is 60, according to the formula T=100-X*2-Y*5-Z in step S140, the obtained score T is 66, then it can be determined that the bellows is in an abnormal state; if according to step S140 In the formula T=100-X*2-Y*5-Z, the obtained score T is 55, then proceed to the next step S170.

In step S170, it is determined whether the score of the bellows is greater than a third value; if so, it is determined that the bellows is in an abnormal state; if not, step S180 is performed.

For example: if the third value is 50, according to the formula T=100-X*2-Y*5-Z in step S140, the obtained score T is 55, then it can be determined that the bellows is in an abnormal state; if according to step S140 In the formula T=100-X*2-Y*5-Z, the obtained score T is 44, then proceed to the next step S180.

Step S180, judging whether the score of the bellows is less than a third value; if so, judging that the bellows is in a serious state.

For example, if the third numerical value is 50, according to the formula T=100-X*2-Y*5-Z in step S150, the obtained score T is 44, then it can be determined that the bellows is in a serious state.

Please refer to FIG. 3. FIG. 3 is a flowchart of the specific steps provided in FIG. 2, which specifically includes the following steps:

In step S151, it is judged whether the score of the bellows is greater than 95; if so, it is judged that the bellows is in a normal state; if not, step S161 is performed.

For example: according to the formula T=100-X*2-Y*5-Z in step S140, the obtained score T is 99, then it can be determined that the bellows is in a normal state; if according to the formula in step S140 T=100 -X*2-Y*5-Z, the obtained score T is 94, then go to S161.

In step S161, it is judged whether the score of the bellows is greater than 90; if so, it is judged that the bellows is in the attention state; if not, step S171 is performed.

For example: according to the formula T=100-X*2-Y*5-Z in step S140, the obtained score T is 94, it can be determined that the bellows is in the attention state; if according to the formula in step S140 T=100 -X*2-Y*5-Z, the obtained score T is 89, then go to S171.

In step S171, it is determined whether the score of the bellows is greater than 80; if so, it is determined that the bellows is in an abnormal state; if not, step S181 is performed.

For example: according to the formula T=100-X*2-Y*5-Z in step S140, the obtained score T is 89, it can be determined that the bellows is in an abnormal state; if according to the formula in step S140 T=100 -X*2-Y*5-Z, the obtained score T is 79, then go to S181.

Step S181, it is judged whether the score of the bellows is less than 80; if so, it is judged that the bellows is in a serious state.

For example, according to the formula T=100-X*2-Y*5-Z in step S140, if the obtained score T is 79, it can be determined that the bellows is in a serious state.
