Recently, with the strong support from the project of "one hundred billion yuan industry" in the autonomous region, Guangxi Electric Power Academy completed the construction of the first sulfur hexafluoride solid analysis laboratory in Guangxi, indicating that the sulfur hexafluoride sulfur dioxide electrical equipment Fault diagnosis technology into a new level.
The sulfur hexafluoride solid decomposition testing laboratory is an important part of the SF6 key laboratory construction in the hospital. It is mainly composed of ICP-MS and related supporting equipment. The system is characterized by high temperature ( 7000K) ionization features combined with the sensitive, fast scanning advantages of quadrupole mass spectrometers for the elemental and isotopic analysis of sulfur hexafluoride for the analysis of elemental composition of sulfur hexafluoride solid decomposition products for rapid diagnosis of internal sulfur hexafluoride electrical equipment failures What happened?
At present, Guangxi Electric Power Academy has completed the installation and commissioning, performance acceptance and technical training of the ICP-MS analysis and testing system, and chemical technicians are working hard to carry out practical application studies. The completion of sulfur hexafluoride solid decomposition testing laboratory, for the safe operation of sulfur hexafluoride electrical equipment to provide a new analytical techniques.
The chain grate is the combustion equipment of coal-fired steam boiler. There are three main types and structures: chain belt grate, scale grate and beam grate.
1. Chain belt grate. The chain belt grate is a wide circular chain belt which is surrounded by and supported on the the front and rear axles via the chain wheels. At present, ZOZEN packaged chain grate steam boiler mainly adopts the large-block chain belt grate with a capacity of 1-20 tph.
2. Scale grate. The scale grate has many advantages. The obvious one is that there is less coal leakage. The scales can be replaced without shutting down the boiler. The ventilation is balanced, and the ventilation section is relatively small (6%). The chain grate bars only bears the stress or high temperature instead of both of them, which improves the working conditions of the chain grate.
3. Beam grate. Its main feature is that the width and length of the grate can be extended in a wide range, and the tonnage of the boiler can be larger. At present, the tonnage of the domestic beam chain grate steam boiler can reach 240 tph. The grate is featured with long service life, good durability, smooth arrangement and convenient replacement.
