Abstract (en)
[origin: EP3373401A1] The present invention generally relates to a disconnector arrangement for surge arresters that are used in protecting electrical equipment against overvoltage. The present invention further relates to a method of fabricating such a disconnector arrangement. The disconnector arrangement comprises a first terminal (102), and a second terminal (104), said first and second terminals (102, 104) being arranged along a longitudinal axis (122) of the disconnector arrangement (100), an electrically insulating enclosure (110) comprising a main body (106) and a cover element (108), the enclosure (110) forming an arc chamber (138) between said first and second terminals (102, 104), a resistor (120) interconnecting said first and second terminals (102, 104), said resistor (120) being arranged in a central region of the disconnector arrangement (100), wherein the arc chamber (138) is ring-shaped and surrounds the resistor (120), a first arc electrode (114), and a second arc electrode (116). The first and second arc electrodes (114, 116) are distanced apart from each other to form an arc gap (136) that is arranged to radially encompass said resistor (120). An explosive material (126) can be thermally activated to detonate when a temperature at the resistor (120) exceeds a threshold value, said explosive material (126) being arranged around the resistor (120) and in a radial direction inside the arc gap (136).
