摘要： The high-voltage isolator (1) has a first electrical connecting element (2a) and a second electrical connecting element (2b) and an electrical insulating element (3) extends therebetween. The end sections (4a, 4b) of the connecting elements (2a, 2b) are connected to the isolating element (3), wherein at least on one of the end sections (4a, 4b) there is a torus-shaped field control element (5). At the end section (4a, 4b) featuring the field control element (5) there is a slot (6) extending in the perimeter direction of the end section (4a, 4b). The field control element (5, 5a) and the associated end section (4a, 4b) are designed as a single piece. Due to the provision of the slot (6), during longitudinal- and transverse contractions of the insulating element (2), any occurring tensile- and compression forces which act perpendicular to the longitudinal axis of the end section (4a, 4b), and also shear forces are generally prevented and a simultaneous retention of a good equalization in the region of the isolating path is achieved in the case of electrical fields occurring during operation.

摘要： The high-voltage insulator contains a metal armature (2), an insulating tube (1) which is joined to the metal armature and is adhesively bonded to the metal armature at an end in the form of a bearing ring (10), and an axially symmetrical adhesive-bonding joint which is guided around the axis (A) of the insulating tube. An annular groove (23) which is guided around the axis of the insulating tube and receives an end section of the bearing ring is formed in the metal armature. A respective sealing surface (24, 13) is formed in the groove (23) and in the bearing ring (10). The two sealing surfaces are arranged and formed in such a manner that they slide on one another when joining the insulating tube (1) and the metal armature (2) so as to form a seal, and the bearing ring (10) which acts as a displacement body presses adhesive (32), which has been introduced into the groove (23), into the adhesive-bonding joint before joining. The insulator and a cooling element containing this insulator are simple to produce and are distinguished by a leakage rate of less than 10
-9 [bar l/s] and by great operational reliability even after many years of operation with a large mechanical, electrical, thermal and chemical load.-

摘要： The apparatus comprises a probe- insulator (3) with an internal cavity, a first system (8/1) that circulates a cold fluid within the cavity (4) of the probe-insulator in order to cool the latter to such a temperature that the external humidity condenses on the external surface, a second system (8/2) for measuring the surface conductivity on the probe-insulator, a third system for activating a washing plant of all insulators installed in the same area when the measured value of said surface conductivity reaches a pre-set critical value; the refrigerating device that produces said cold fluid preferably includes a group of Peltier modules.
