摘要： PURPOSE:To prevent the contact of a bypass breaker from damage due to mixed contacting of two kinds of power supplies or generation of arcs by incorporating bypass breaker and a changeover switcher in a single body, and interlocking the two members. CONSTITUTION:When No.1 contact 3 of a switcher 2 is in opened state, a detent part 18 interlocked with the No.1 contact 3 blocks the way of motion of another detent part 28 interlocked with a bypass breaker 5 so as to hinder the breaker 5 from closing operation. This prevents generation of arcs to be generated by turning-on of the breaker 5 or the trapping current, and there is no risk of damaging the contact. When the bypass breaker 5 is in closed state, the detent part 28 interlocked with the breaker 5 blocks the way of motion of the abovementioned detent part 18 interlocked with No.2 contact 4 so as to hinder No.2 contact 4 from closing operation. Thus there is no risk of a large current flowing caused by mixed contacting of No.1 power source and No.2 power source with the load side.

摘要： PROBLEM TO BE SOLVED: To prevent an electrical shock accident of touching an electrode terminal for switch connection exposed from a mount frame after pulling out a switch.SOLUTION: For a power supply switching device, a mount frame 2 attached to a panel 1 for a board is loaded with a power supply switch 3 including a terminal part connected with an electrode plate through an opening 2a of the mount frame 2 so as to be pulled out to the front. A receiving shelf 7 slidable together with the power supply switch 3 is provided so as to be freely raised and brought down on a lower part of the mount frame 2, and by pulling out the receiving shelf 7 to the front and then erecting it, the opening 2a of the mount frame 2 is shielded, and thus an electric shock accident is prevented. Also, since the receiving shelf 7 can be slid according to pull-out of the power supply switch 3, the power supply switch 3 is received by the receiving shelf 7, and the accident of dropping the power supply switch 3 or the like is prevented.
摘要翻译：要解决的问题：为了防止在拉出开关后触摸从安装架露出的开关连接的电极端子触电事故。解决方案：对于电源开关装置，安装到用于板的面板1的安装框架2装载有电源开关3，电源开关3包括通过安装框架2的开口2a与电极板连接的端子部分以便被拉出到前面。与电源开关3一起滑动的接收架7被设置成能够在安装架2的下部自由地升高并降低，并且通过将接收架7向前拉出，然后将其竖起来，安装框架2的开口2a被屏蔽，因此防止了电击事故。此外，由于接收架7可以根据电源开关3的拉出而滑动，所以电源开关3被接收架7接收，并且防止了掉电电源开关3等的事故。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an emergency connection circuit which can speedily, easily and safely constitute an emergency connection circuit by a preliminary transformer when a transformer connected between a bus bar and a plurality of branch lines breaks down, and to provide a connection device used for the emergency connection circuit. SOLUTION: Connection to sides of branch lines 72, 76 and 80 in the preliminary transformer 106 is performed by connecting the connection device 14 to an input terminal 118 after a preliminary branch line breaker 86 is detached from a preliminary branch line 84. The connection device 14 has a truck which can move on rails of the preliminary branch line breaker 86 and a relay electrode terminal which is arranged in the truck and in which one end is connected to a connection terminal of a cable 110 connected to the preliminary transformer 106 and other end is connected to the input terminal 118 of the preliminary branch line breaker 86. Thus, the emergency connection circuit by the preliminary transformer can speedily, easily and safely be constituted. An electric isolation distance between a connection point of the preliminary breaker with a branch line side and the other high pressure unit can sufficiently be secured. COPYRIGHT: (C)2009,JPO&INPIT
