Abstract

A clamping force sensor assembly for a transformer includes at least one sensor disposed within a casing. The design and configuration of the sensor assembly is such that it accurately measures clamping force values placed on the windings, without adversely impacting the operation of the transformer and with the ability to continue operating under electrical and thermal changes within the transformer. The sensor assembly can include loading members that distribute the pressure evenly over the casing that contains the sensor. The output of the sensor can indicate to an operator the extent of pressure changes experienced by the transformer windings. The output can be coupled with a process by which the damage to or the possibility of failure of the transformer is readily evaluated.

Abstract

An improved dryer (1) dehumidifying the air intended for oil expansion tanks used in electrical equipments including a dehumidification container (2), which presents an inlet for the air to be dehumidified and an outlet (3) for the dehumidified air, absorption means (4), contained in the dehumidification container (2) and which dehumidify y the air coming from the outside, heating means (5), positioned inside the dehumidification container (2) and which regenerate the absorption means (4), detection means (6) of the dehumidification degree of the absorption means (4), operatively connected with the heating means (5), which determine the saturation state of the absorption means (4). The detection means (6) include a transducer (7), coupled to the dehumidification container (2), which directly measures the degree of dehumidification of the absorption means (4).

Abstract

A detachable connecting device for vacuum tap changers (10) for electrical transformers, of the type suitable to constitute at least a fixed contact (12), which is positioned on a tap changer (10) rod-shaped body (11) associated with drive actuators means (13) acting on supports (15) containing mobile contacts set to a reference voltage and sliding on fixed contacts (12); in particular, the detachable connecting device comprises a pin (23) on which is preassembled an elastic element kept in position by a peg (24) placed orthogonally to the walls of the pin (23). The pin (23), inserted into a shaped bush (29) which is inserted, in turn, in a respective opening of the rod-shaped body (11) of the tap changer (10), is pushed beyond the thickness of the aforesaid rod-shaped body (11) and rotated in any direction, in such a way to bring the peg (24) within a seat (39) provided on a surface of the bush (29).
