System Introduction
The vibration detection and analysis system of the mold vibration table consists of two parts: dynamic signal acquisition instrument and sensor. Among them, the dynamic signal acquisition instrument is based on a portable industrial control computer, with hardware integrated signal acquisition module and secondary instrument, and pre-installed with dynamic signal detection and analysis software with completely independent intellectual property rights. It is the core of the vibration detection and analysis system of the crystallizer shaking table. The sensor consists of a CCD laser displacement sensor, two eddy current position sensors, a tilt sensor, a sensor mounting bracket and a test datum suction cup.

The transformer dynamic load intelligent management system is used to solve the problems of low operating efficiency of large transformers, difficulty in internal temperature monitoring, and limited operation of transformers under heavy (over) load, and to improve the operating efficiency of transformers without affecting the service life and safe operation of transformers.
The dynamic load management system of transmission line is used to solve the problems such as limited load capacity of transmission line and difficult to meet the demand of load growth, and to improve the operation level and load capacity of the line without changing the existing network structure and without affecting the thermal stability of the line.
Due to the technical limitations of the traditional transmission line fault location device, it is difficult to quickly and accurately locate the fault point and identify the fault type when the fault of the transmission line occurs in the complex operating environment (lightning strike, mountain fire, wind deviation, tree barrier, floating object, etc.). The distributed fault diagnosis device for transmission lines is based on fault local recording technology and traveling wave location method, which can effectively solve the problems of low positioning accuracy and difficult identification of fault types of traditional fault location devices.
