摘要： Methods, apparatuses, systems, computer readable media and a computer product for detecting a gas leak of a gas tank. In a method, at least one inside temperature is determined for the gas tank based on a plurality of outside temperatures that are collected outside the gas tank, the at least one inside temperature being estimated for at least one inside position within the gas tank during an operation of the gas tank (310). A gas pressure within the gas tank under a standard temperature is obtained based on the at least one inside temperature (320). The gas leak of the gas tank is detected based on the gas pressure (330). An inside temperature of the gas tank is determined and used for detecting the gas tank, therefore the gas leak may be detected in a more accurate and effective way.

摘要： According to implementations of the subject matter described herein, there is provided a method, an electronic device and computer readable storage medium for monitoring gas pressure. The method comprises: determining a first reference measurement from a set of historical measurements of gas pressure inside a hermetic container; in response to a determination that a current gas pressure measurement is below the first reference measurement by a first threshold, determining a first variation trend of a gas leaking velocity of the hermetic container; and determining, based on the first variation trend, an expected time duration for the gas pressure to reduce from the current gas pressure measurement to a threshold pressure. Information about when the gas pressure will drop to the threshold pressure can be provided.

摘要： A potential transformer isolating device comprises a swinging rod (11,31), a guide pole(14,34), and a compression device(13,33). The guide pole (14, 34) has a guide-pole guide end (142,342) and an arc-shaped guide-pole connecting end (141,341). When the guide-pole connecting end (141,341) is under the action of the external force, the guide pole can move along the swinging rod (11, 31), and the compression device (13,33) is compressed. When the external force is removed, the guide pole (14, 34) can be reset under the action force of the compression device (13, 33). Therefore, the design of the telescopic round stick is good for improving the insulation levels of the gas insulated switchgear and the control device.
