| A simple, economically efficient, synchronized switching system for control of a three phase motor contactor utilizes only Voltage monitoring to determine zero crossings and knowledge of the sinusoidal power waveforms and operational delay period of the contactor, to synchronize operation of the contacts at low power. The phases can be serially utilized for zero crossing detection upon Close or Open commands, so as to spread the wear over each set of contacts. Expensive metal at the contact surfaces can therefore be used more efficiently. For arc energy reduction upon contact opening, knowledge of Line-Load Voltage on at least one phase can be used to derive an empirical determination of the voltage angle at opening which yields the lowest arc energy. | ||||||

Said aim is achieved whereby the contact pieces which may be displaced relative to each other are moved with a relatively high speed during a first phase (S1) of the separation process until about ¼ to ½ of the ultimate separation (extinction stroke Eh) and are brought to the given ultimate separation (isolating stroke Eh) during a second phase (S2) with relatively low speed. | ||||||

| PURPOSE: A vacuum switching apparatus is provided to be capable of improving the usability, reducing the possibility of mis-operation of an operator, and simplifying and miniaturizing the operating mechanism. CONSTITUTION: A vacuum switching apparatus for automatically performing a series of breaking and disconnecting operations includes a fixed electrode(3) and a movable electrode(2) mounted in a vacuum vessel(4). The movable electrode is sequentially movable between a closing position(Y1), an opening position(Y2) and a disconnecting position(Y3). After the movable electrode passes through the opening position located between the closing position and the disconnecting position, the between-electrode opening speed of the movable electrode is reduced by a decelerating means. With this configuration, it is possible to move the movable electrode from the closing position(Y1) to the disconnecting position(Y3) without lowering the braking performance, and hence automatically to perform a series of the braking and disconnecting operations. | ||||||

| A contact thermostatic switch has a dished, snap-acting bimetallic disc (5) cantilevered from one end of a diameter whereat the edge of the disc is loosely retained between a housing moulding (1) and a metal cap (6) secured to the moulding. At the other end of this diameter, the edge of the bimetallic disc engages a pip (4d) on one end of a lever (4) which is pivotally-mounted in the housing at its other end. When the bimetallic disc (5) snaps to its oppositely dished configuration, it moves the pivotally-mounted lever (4) so as to determine the condition of a set of switch contacts by virtue of the end of the lever (4) which carries the pip (4d) also having depending fingers (4c) which abut a moving-contact carrying leaf spring (2b) of the switch. The cantilevered mounting of the bimetallic disc and its interaction with the lever enables a smaller than conventional disc to be used, with consequent significant cost savings, without prejudicing the operation of the switch. | ||||||
