GIESSHARZISOLIERTER MESSWANDLER, INSBESONDERE STROM- UND SPANNUNGSWANDLER

摘要

In order to be able to assemble in modular form a measurement transformer which is insulated by potting resin and has a separately produced high-voltage bushing, without any intermediate flange and/or a housing being required around the active parts of the transformer, the upper free end edge (6) of the potting resin moulding (4) is lengthened upwards in the form of a collar. The collar-shaped extension (7) encloses a rotationally symmetrical cavity (8) in such a manner that that part (9) of the high-voltage bushing (10) which is not insulated for the open air can be inserted into this cavity (8) and can be connected to the high-voltage connection (11) of the measurement transformer (1). The remaining annular space (18) is filled with insulating material and is closed by a flanged part (13) of the high-voltage bushing (10) in a gas-tight or liquid-tight manner. <IMAGE>
