Super-huge type extra-high voltage transformer weighing system and method

Abstract

The invention discloses a super-huge type extra-high voltage transformer weighing system. The system comprises multiple weighing modules, straingauge type transducers arranged inside the weighing modules respectively and hydraulic jacks arranged at the lower ends of the weighing modules respectively, wherein the hydraulic jacks are connected with a hydraulic pump station through hydraulic pipelines, the weighing modules are evenly arranged at the bottom supporting positions of a transformer to be weighed in a supported mode, and the output ends of the straingauge type transducers are connected to the input ends of weighing instruments through signal transmission cables. The weighing method of the system comprises the steps of (1) evenly arranging weighing modules supported by hydraulic jacks at the bottom supporting positions of a transformer to be weighed, wherein straingauge type transducers connected with weighing instruments are arranged inside the weighing modules; (2) adjusting the initial heights of the hydraulic jacks one by one to enable the weighing modules on the hydraulic jacks to sustain the bottom of the transformer to be weighed; (3) starting the hydraulic jacks to enable the hydraulic jacks to be in place, and calculating the sum of values displayed by the weighing instruments corresponding to the weighing modules respectively to obtain the weight of the transformer to be weighed.

Description

technical field [0001] The invention relates to the field of power transformer manufacturing, in particular to a weighing system and method for extra-large ultra-high voltage transformers. Background technique [0002] At present, most transformers are weighed by lifting equipment with scales or directly using floor scales. With the development and production of extra-large ultra-high voltage transformers, while the capacity and voltage level of transformers continue to increase, the size and weight of transformers also continue to rise. Traditional transformer weighing methods, such as figure 1 As shown, the lifting equipment needs to cooperate with the weighing method of the scale to weigh the transformer. During the operation, the lifting equipment needs to be used to lift the transformer off the ground. Due to the limitations of the lifting height and its own weighing limit, it is impossible to complete the ultra-large ultra-high voltage transformer. weighing task. In ...

Problems solved by technology

Traditional transformer weighing methods, such as figure 1 As shown, the lifting equipment needs to cooperate with the weighing method of the scale to weigh the transformer. During the operation, the lifting equipment needs to be used to lift the transformer off the ground. Due to the limitations of the lifting height and its own weighing limit, it is impossible to complete the ultra-large ultra-high voltage transformer. The weighing task

In addition, this weighing method uses a lot of equipment and often needs to be carried out at a designated point. The operation is time-consuming and laborious, the equipment cost is high, and the weighing accuracy is not high.

The method of weighing ordinary transformers by means of floor scales, except that there is no limit to the above-mentioned hoisting height, other shortcomings are still unavoidable
