The gas-insulated switchgear device includes a pair of spaced apart main bus lines, three circuit breakers connected between the main bus lines, a common space for dismantlement and inspection work provided between two of the three circuit breakers, and branch bus lines provided above the common dismantlement and inspection work space using the common dismantlement and inspection work space and disposed in such a manner that insulatedly leading-out directions of the branch bus lines cross in order to balance voltage. Even if the three circuit breakers are disposed along axial directions of the main bus lines, the dismantlement and inspection work space can be also used for arranging of the branch bus lines, whereby an installation area for the gas-insulated switchgear device can be reduced in a juxtaposition direction of the circuit breakers.

摘要： In an apparatus capable of distilling and refining an easily polymerizable substance, piping is performed so that when a strainer in action is switched to a backup strainer, the strainer can be switched after removing air in the backup strainer to replace air in the backup strainer with a discharge liquid of a pump. According to the apparatus, switching the strainers installed on an upstream side of the pump for extracting a liquid of a vacuum distillation column, which distills and refines the easily polymerizable substance, can be performed with no trouble during operation of the distillation column. When the apparatus includes a device for measuring a differential pressure between an upstream side and a downstream side of the strainer in action, two or more strainers installed in parallel can be switched at proper times and the easily polymerizable substance can be produced efficiently.
