摘要:
A power operator for switchgear for use in mains power distribution systems such as public medium high voltage distribution systems, where the switchgear comprises a closed cabinet (5) with an operating shaft protruding there from. The operating shaft is rotable at least between two positions and has a coupling part. The motor operator comprises a housing (11, 20, 21, 27), which is mountable on the external surface (4) of the switchgear cabinet (5), and a rotatable connection shaft connected to an electric motor via a transmission. It has a first coupling part to fit with the coupling part of the switchgear in a longitudinal axial sliding and non- rotational interlocking manner. The housing (11, 20, 21, 27) is a tube element which has the inherit quality that it does not invite to vandalism and unauthorized access. It is relatively easy to seal against dust and moisture. When cut from a length of a pipe it is easy to manufacture as well as inexpensive.

摘要:
A motor operator for switchgear for use in mains power distribution systems comprising a closed cabinet (5) with an operating shaft (53) protruding there from said operating shaft being rotatable at least between two positions and has a coupling part (2). The motor operator (6, 7) comprises a housing mountable on the external surface of the switchgear cabinet. A rotatable connection shaft (51) is connected to an electric motor via a drive mechanism, and has a first coupling part (52) to fit with the coupling part (2) of the switchgear in a non- rotational interlocking manner, and further has a second coupling part (54) extending from the housing to operate the contact of the switch manually and, for which purpose, the motor operator has a release mechanism releasing the connection shaft. The motor and the drive mechanism is designed as an electro-mechanical actuator with a rear mounting (23) for mounting the actuator in the housing of the motor operator and μ. front mounting (29) on the activation element (20) for connection of the activation element to the rotatable connection shaft (51).
摘要:
A power operator for switchgear (1) for mains power distribution systems, where the switchgear comprises a closed cabinet (5) with an operating shaft protruding there from. The operating shaft is rotable at least between two positions and has a coupling part (2, 3). The operator comprises a housing (10), which is mountable on the external surface (4) of the switchgear housing, and a rotatable connection shaft (14) connected to an electric drive mechanism (11). It has a first coupling part to fit with the coupling part of the operating shaft in a longitudinal axial sliding and non-rotational interlocking manner. The coupling part of the connection shaft (14) is a separate interchangeable part (24, 24a) of the connection shaft attached thereto by non-rotational interlocking means. Further, it has an activation knob (16) extending from the housing (10) to operate the switch manually. With an interchangeable coupling part (24, 24a) the motor operator could easily be adapted to various switchgear simply by choosing a coupling part (24, 24a) fitting the coupling (2, 2a, 3) on the switchgear.
摘要:
An electric hand control, especially for electrically adjustable hospital and care beds and comprising a housing (1) constructed as a single trough shaped shell with a bottom and side walls, and wherein a printed circuit (2) with switches is mounted and above the switches there is a plate with tongue like shaped keys, and finally there is a cover foil (6) with indication of the keys and secured to the upper edge of the sides of the shell. As the housing is a single shell for one thing manufacturing of two difficult parts is avoided, for another assembling of these are avoided in the assembling process, and finally an assembling with a risk of leak is avoided. By further equipping the printed circuit and the cable with a plug (12a) the assembly is made easier. In this connection it is expedient that the spout (10) is equipped with an oval through going hole, so that the plug at the end of the cable can be led through the spout.
摘要:
An electric hand control, especially for electrically adjustable hospital and care beds comprising a number of activation switches (3;3a,3b), and a number of locking switches (9, 10;11 ;13, 14), which can be activated by means of a locking element (7) by which means the circuit for the activation switches (3;3a,3b) is cut off, so that the function belonging to it becomes inactive or locked. In an embodiment the locking switches are on-/off switches and in another embodiment the locking switches are based on a read switch and a magnet and in yet another embodiment the locking switches are based on a wave shaped disc (9) mounted over two contact points (10).
