<p>PURPOSE:To discharge residual electric charge by taking off ground switch lever arranged in a frame body for element from a guide arranged to containing part and connecting a contactor with a terminal for high voltage connection at the time of removing the element. CONSTITUTION:The guide 18 is arranged in the containing part 2 for element and ground switch composed of the ground switch lever 16 and supporting member 17 is arranged at lower part of the frame body 9 for dust collecting element. By pushing the lever 16, the contactor 14 is turned against a spring, one end of the contactor 14 is separated from the terminal 10 for high voltage connection. Therefore, at the time of slidingly inserting the dust collecting element 1 into the containing part, 2 the contactor is separated from the termi nal 10 and the high voltage is charged to the element 1. At the time of pulling out the frame body 9 for element 1 in order to exchange, the lever 16 is taken off from the guide 18 and the connector 14 is brought into contact with the terminal 10 through the spring, and the residual charge is perfectly discharged. Therefore, the exchanging work can safely be executed.</p> |
