A pressure sensor includes a sensor housing including an opening portion having different dimensions in a longitudinal direction and a transverse direction, a sensor chip that is provided on the sensor housing in a manner of closing the opening portion and that forms a diaphragm portion, a strain gauge portion provided in the sensor chip, and a cap member bonded to the sensor chip by a cap bonding agent. Among bonding surfaces of the cap bonding agent, bonding surfaces at both longitudinal direction end portions of the diaphragm portion each have a bonding area larger than that of bonding surfaces at both transverse direction end portions of the diaphragm portion. Accordingly, it is possible to prevent breakage or the like of the diaphragm portion in the pressure sensor and to maintain pressure detection sensitivity.

This invention belongs to the technical field of power system monitoring and relates to an intelligent operation and maintenance risk early warning method for transmission equipment in harsh environments. The method includes the following steps: synchronously collecting sensor and meteorological data; calculating a dynamic benchmark based on an association model and differentially generating state residual signals; monitoring vibration residuals and triggering a hardware interrupt when conditions are met to synchronously capture high-frequency waveforms of leakage current and temperature during fault transients; extracting feature vectors through dimensionality reduction encoding of the data and generating residual coupling fingerprints by combining them with timestamps; mapping the fingerprints to state trajectories and calculating their geometric similarity to standard templates in a fault topology library to generate targeted early warnings; and dynamically adjusting the acquisition parameters and updating the association model based on the early warning results. This invention solves the problem that existing transmission equipment monitoring methods struggle to isolate environmental interference, leading to low early warning reliability and difficulty in accurately characterizing faults.
