Problems solved by technology
This method of testing the vacuum degree is accurate in test results, but it has high requirements for the detection device and the detection environment. Therefore, it is obviously not appropriate to use this device to detect the vacuum degree when the accuracy of the vacuum degree test is not too high. Suitable

The invention discloses a vacuum switch online detection method. The method comprises the steps: installing an information collection module on a vacuum tube of a vacuum switch, transmitting a signalcollected by the information collection module to a data processing module, and enabling the data processing module to carry out the real-time detection of the vacuum degree of data processing. The information collection module comprises a temperature sensor and an ultrasonic sensor which are arranged on a vacuum tube. According to the invention, the plurality of temperature sensors and ultrasonicsensors are arranged on the vacuum tube of the vacuum switch to realize the purpose of detecting the vacuum degree; the vacuum degree judgment value is obtained after the temperature signal and the ultrasonic signal are weighted, whether the vacuum degree leaks or not is preliminarily judged according to the vacuum degree judgment value, traditional complex detection is avoided, and the detectionmethod is simple.
Description
technical field [0001] The invention belongs to the field of on-line monitoring of a vacuum switch, and in particular relates to an on-line detection method of a vacuum switch. Background technique [0002] The vacuum switch is a pressure (including negative pressure) container and pipeline. The purpose of vacuuming is to test its tightness and exhaust the internal air to prevent the moisture in the air or the existence of the air itself from affecting the normal operation of the equipment. As equipment that needs to work in a vacuum state, if the vacuum degree is broken or the vacuum degree is reduced, the performance of the equipment will be seriously affected. It is necessary to check the vacuum degree regularly, so that potential chronic air leakage and other potential problems can be found early. defects to prevent accidents. [0003] At present, most of the methods for detecting the degree of vacuum are measured by the magnetron discharge method. The two contacts of t...
