Abstract:
PCT No. PCT/DE89/00063 Sec. 371 Date Dec. 8, 1989 Sec. 102(e) Date Dec. 8, 1989 PCT Filed Feb. 2, 1989 PCT Pub. No. WO89/11338 PCT Pub. Date Nov. 30, 1989.A safety circuit arrangement for the high-voltage generator of an electrostatic filter, in particular of an electrostatic soot trap for diesel internal-combustion engines including a grounded filter housing and a filter electrode, has a power supply (15) which is connected to the high voltage generator (20) via controllable switching means (34). A and a shielded high-voltage cable (17), the high-voltage line (18) of which connects an output (24) of the high-voltage generator (20) to the filter electrode (14). To eliminate the risk to people caused by components carrying high voltage, the shield (19) of the high-voltage cable (17) is connected at one end to the filter housing (11), and at the other end to a control device (25) in such a way that an interruption of the shield (19) leads to the generation of a control signal for the switching means.
