Description
Technical Field
[0001] The utility model relates to the technical field of GIS casings, in particular to a tool for measuring the size of GIS casings. Background Art
[0002] During the assembly and manufacturing of the transformer, the insulation distance of each part needs to be controlled to ensure that no breakdown discharge will be caused during the test. Similarly, after the assembly is completed, it is still necessary to pay attention to the external installation dimensions. This data plays a vital role in the on-site installation. After the transformer is transported to the site, the external wiring and power-on operation are carried out. For example, the GIS bushing end needs to be connected to the on-site line. The bushing has strict requirements on the external dimensions to the ground. If the maximum deviation is exceeded, it will lead to the inability to install on-site. On-site repairs not only generate expensive repair costs, but also have certain safety and quality risks. What's more, if the on-site repair conditions are not available or cannot be repaired, it will seriously affect the on-site live operation. If the transformer is returned to the factory for repair, it will also cause significant economic losses.
[0003] Most of the existing casing size measurements are performed by manual handheld measuring tools to measure the lateral side. When the manual handheld device measures the length of the casing, the casing needs to be pressed down manually, which causes inconvenience in measurement. Due to the low accuracy of manual measurement, the height and length measurements of the casing need to be measured and processed separately, resulting in low efficiency. At the same time, multiple people are required to operate the length measurement of casing that is too long, which increases labor costs and is time-consuming and labor-intensive. Therefore, it is particularly important to improve the existing measuring tooling and design a new GIS casing size measurement tooling to solve the above technical defects and improve the practicability of the overall measuring tooling.
