Definitions
- the invention relates to a circuit breaker with a locking device against switching on, the locking device a security lock with one only in the exhibition of the circuit breaker has a removable key.
- a circuit breaker of this type is through the DE catalog Siemens: Protection equipment catalog NS1 1988, page 3/7 became known.
- a security lock can be used as a locking device also use a flap that via those provided to control the circuit breaker Push buttons "OFF” and electrically "ON” and with up to four Padlocks can be secured.
- the object of the invention is to achieve this based on overcoming these restrictions and others To create opportunities for backup.
- a lockable protective device is arranged in front of the security lock is only when the security lock is removed Key can be moved into its locked position.
- This Arrangement creates the possibility, for example, of several Circuit breakers with security locks of the same closure equip, but by providing only one Key only one of the circuit breakers put into operation can be. The closed and therefore not switchable However, circuit breakers can now be made of maintenance or repairs through a padlock Fitter or an operator additionally secured become. In this state there is no way to Only try the key of the security lock to plug in.
- the lockable protective device can be a security lock front panel to be mounted and an articulated have closure flap connected to the cover plate, and the cover plate and the flap can be used to cover openings to hang a padlock be provided.
- This is suitable in this version Protective organ good for retrofitting with Circuit breakers provided with safety locks. Especially can make the subsequent attachment easier be that the protective organ at one the security lock covering lock housing is attachable.
- One for the construction of the protective organ and its handling equally advantageous design can consist in that the openings in each end leg of the cover plate and the flap and that the end legs one connecting the cover plate and the flap Hinge joint are arranged opposite one another.
- Figure 1 shows schematically a low-voltage circuit breaker with a control panel.
- a protective device for a safety lock on the control panel of the circuit breaker according to Figure 1 shows a perspective Representation of Figure 2.
- Figures 3 and 4 show a section through the control panel of the circuit breaker according to Figure 1 in the area of the mentioned security lock. 3 shows this the state with the key inserted and open Protective flap of the protective organ, while Figure 4 shows the condition with closed protective flap and attached padlock represents.
- the circuit breaker 1 has a control panel 2 with controls for controlling the circuit breaker 1 on. Between one on the left side of the Control panel located electronic trigger 3 and a hand lever 4 assigned to the right side for tensioning a spring accumulator there are pushbuttons for switching on and off Opening the circuit breaker 1. Below one for Switching off pushbutton 5 is a dashed line shown security lock 6, which is a protective organ 7 is assigned. The protective member 7 is by a padlock 10 shown cordoned off. Details of the protective organ 7 are explained below with reference to FIG. 2.
- the protective member 7 has a cover plate 11, which with an opening 12 for access to the security lock 6 and with two smaller openings 13 for attaching the Protective organ 7 is provided on the control panel 2. With the Cover plate 11 is a by means of a hinge joint 14 Protective flap 15 articulated.
- the cover plate 11 has a lower end leg 16 with four openings 17 for Hook in the padlock 10 shown in FIG. 1 or optionally other such padlocks.
- the Protective flap 15 also has an end leg 20 which is provided with four openings 21 for the purpose mentioned. By pivoting the protective flap 15 in the direction of an arrow 22 shown in FIG End legs 16 and 20 are aligned with one another in such a way that the openings 17 and 21 correspond to each other, around the lock shackle of the padlock 10 (FIG. 1) to be able to hang up.
- FIGS 3 and 4 show more details in one Section through the control panel 2. From these figures is to see in more detail that the security lock 6 a locking bolt 23 and a lock housing 24, which over the level of the control panel 2 protrudes.
- the protective organ 7 is by means of its openings 13 of the cover plate 11 on the front attached to the lock housing 24. With the protective flap open 15 is a key 25 in the security lock 6 introduced to the pivot bolt 23 to lock the circuit breaker 1 ( Figure 1) to secure against switching on.
- a locking mechanism 26 of the circuit breaker 1 is in the Figures 3 and 4 indicated schematically. By from the push button 5 and arrows coming from the security lock 6 is illustrated that the locking mechanism is first by the Pushbutton 5 is applied to the circuit breaker turn off and that this condition through the security lock 6 is then saved.
- FIG. 4 the arrangement according to FIG. 3 is drawn off Key shown, the protective flap 15 of the Protection device 7 swung down and the padlock 10 into the openings of the end legs that are now covered 16 and 20 is mounted.
