Insulator arrangement on a capacitive security fence (protective fence)

摘要

Insulator arrangement on a capacitive intrusion-security fence. A security fence which has transmitter electrodes (SE) and receiver electrodes (EE), which are fed by a transmitter (SEN), are fastened in each case by means of insulators (ISO) on the security fence or on support poles (MA) and form an electrode system (ESY), has in addition at least one auxiliary electrode (HE) which is connected directly to the transmitter (SEN). Furthermore, an upper and a lower cross beam (QTo, QTu) are arranged on each support pole (MA), between which cross beams insulators are fastened which are formed by insulating cables (IE; IE), to which the electrodes (SE, EE; HE) are fitted. <IMAGE>
