Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example 1: as shown in fig. 1, the ready indicating member 2 is a substantially fan-shaped cylindrical surface structure, and has an arc-shaped status indicating panel 25 thereon, and three status indicators "energy storage OK", and "energy release" are listed on the status indicating panel 25, which respectively indicate a closing ready status, an energy storage but closing disabled status, and an energy release status; the ready indicating member 2 is also structured to include a travel limit control hole 26, a link half shaft 24, a latch arm 23, a limit surface 22 and a working surface 21.

As shown in fig. 2, the circuit breaker operating mechanism is provided with a closing and opening indicating member 1, a ready indicating member 2, an opening half shaft 3, a mechanism rotating shaft 4, a closing lever 5, a return spring 6, a closing half shaft 7, a closing button 8, a first shaft 9, a second shaft 10 and a cam 11. Wherein the ready indicating member 2 is mounted on the first shaft 9 with a travel limit control hole 26 passing through the second shaft 10 for rotational limit. The whole operating mechanism is in linkage fit with a connecting rod half shaft 24, a locking arm 23, a limiting surface 22 and a working surface 21 on the ready indicating component 2 respectively through a mechanism cam 11, a cantilever 41 on a mechanism rotating shaft 4 and a switching-off half shaft 3, the integrated energy storage/release state and switching-on ready indicating component 2 of the circuit breaker rotates and limits in the direction A or B around a first shaft 9, and the indicating surface 25 on the integrated energy storage/release state and switching-on ready indicating component 2 of the circuit breaker is enabled to present different position states in a visible window 82 of a circuit breaker cover.

The integrated structure display of state indication is realized by means of mutual linkage among the connecting rod half shaft, the lock catch arm, the limiting surface and the like, the mechanism cam, the mechanism rotating shaft cantilever and the separating brake half shaft, and the integrated structure display has the advantages of simple principle, reliable action, convenience in installation and low cost.

As shown in fig. 4, 5 and 6, when the circuit breaker operating mechanism is in the release and closing state, the link half shaft 24 of the ready indicating member 2 acts on the closing lever 5 to move the closing lever 5 to its extreme position in the direction C. Meanwhile, the working surface 21 in the ready indicating component 2 is in interference linkage with the outer circular surface 111 of the cam 11, the ready indicating component 2 rotates to the limit position along the direction a around the first shaft 9, at this time, the word "energy release" ON the state indicating panel 25 in the ready indicating component 2 is displayed ON the visible window 82 of the circuit breaker mask, and meanwhile, the mark word displayed ON the visible window 82 of the circuit breaker mask in the closing and opening indicating component 1 is "ON" because the circuit breaker mechanism is in a closing state.

Fig. 7, 8 and 9 show that the circuit breaker operating mechanism is in the energy releasing and opening state after the circuit breaker operating mechanism performs opening operation based on fig. 4, 5 and 6. The working surface 21 of the ready indicating member 2 is still in interference linkage with the outer circular surface 111 of the mechanism cam 11, and the ready indicating member 2 is at the rotation limit position in the direction a around the first shaft 9. At this time, the word "energy release" on the indication surface of the status indication panel 25 in the ready indication member 2 is displayed on the breaker cover visual window 82, and the word "OFF" of the sign displayed on the breaker cover visual window 82 in the closing and opening indication member 1 is set because the breaker mechanism is in the opening state.

When the circuit breaker operating mechanism is operated to charge energy, the mechanism cam 11 rotates clockwise to the position shown in the figure, the ready indicating member 2 rotates around the first shaft 9 in the direction B due to the restoring force of the return spring 12, and the working surface 21 of the ready indicating member 2 falls into the locking hole 112 of the mechanism cam 11. Since the second shaft 10 passes through the travel limit control hole 26 in the ready-indication member 2, when the ready-indication member 2 rotates in the direction B around the first shaft 9, the second shaft 10 plays a role of limiting, that is, the ready-indication member 2 is limited to stay at the limit position of the rotation in the direction B. When the energy storage of the circuit breaker operating mechanism is finished, the closing lever 5 horizontally moves towards the direction D under the action of the restoring force of the restoring spring 6, at the moment, the closing button cantilever 81 is positioned on the action surface 51 of the closing lever 5, the action surface 51 of the closing lever 5 is positioned on the tripping surface 71 of the closing half shaft 7, and according to the linkage relation of the three components, when the closing button 8 is pressed to rotate along the anticlockwise direction, the closing half shaft 7 can be driven to rotate along the anticlockwise direction, so that the circuit breaker operating mechanism is enabled to be closed. At this time, "energy storage OK" characters on the indication surface of the state indication panel 25 in the integrated energy storage/release state and closing preparation ready indication component 2 of the circuit breaker are displayed on the visual window of the circuit breaker mask, which indicates that the circuit breaker is in a closing preparation ready state at present, and closing operation can be performed. Meanwhile, the circuit breaker operating mechanism is still in an opening state, so that the identification characters displayed on the visible window of the circuit breaker mask in the closing and opening indicator 1 are OFF.

As shown in fig. 13, 14 and 15, the circuit breaker operating mechanism is switched on by pressing the switch-on button 8 on the basis of fig. 7, 8 and 9, and the operating mechanism automatically stores energy due to the pre-energy storage function of the circuit breaker itself, and at this moment, the circuit breaker operating mechanism is in the energy storage switch-on state. When the circuit breaker operating mechanism is switched on, the mechanism rotating shaft 4 rotates clockwise, the cantilever 41 on the mechanism rotating shaft acts on the limiting surface 22 of the ready indicating component 2 to drive the ready indicating component 2 to rotate around the first shaft 9 along the direction A, when the circuit breaker operating mechanism is switched on, the mechanism rotating shaft 4 is stopped at a fixed position, the cantilever 41 on the mechanism rotating shaft abuts against the limiting surface 22 on the ready indicating component 2 to reach a certain position, the position of the off ready indicating component 2 is fixed due to the restoring force of the return spring 12, and the character 'energy storage OK' on the indicating surface of the state indicating panel 25 in the ready indicating component 2 is displayed on the circuit breaker mask visual window 82, which indicates that the current circuit breaker operating mechanism has stored energy and can not be switched on. Meanwhile, because the circuit breaker operating mechanism is already in a closing state, the identification characters displayed ON the visible window of the circuit breaker mask in the closing and opening indicating part 1 are 'ON'.

As shown in fig. 16, 17, and 18, on the basis of fig. 7, 8, and 9, when the undervoltage power is lost or the electronic release is in an abnormal state, the opening half shaft 3 will rotate clockwise due to the action of the undervoltage or the electronic release, the connecting rod 32 thereon will contact the straight gear 52 of the closing lever 5 to drive the closing lever 5 to translate along the C direction, at this time, the closing button cantilever 81 is staggered from the action surface 51 of the closing lever 5, and when the closing button 8 is pressed to rotate counterclockwise, it cannot act on the releasing surface 71 of the closing half shaft 7 through a linkage relationship, so that the circuit breaker operating mechanism cannot be actuated to close. Meanwhile, when the opening half shaft 3 rotates clockwise, the latch plate 31 thereon will act on the latch arm 23 of the ready indicating member 2, at which time the ready indicating member 2 will rotate in the direction a around the first shaft 9, and the ready indicating member 2 will be stopped at a specific position under the combined action of the restoring force of the return spring 12. At this time, the word "energy storage OK" on the 25 indicating surface in the ready indicating component 2 is displayed on the visible window of the circuit breaker mask, which indicates that the current circuit breaker operating mechanism has already stored energy but can not perform closing operation. Meanwhile, because the circuit breaker operating mechanism is still in the opening state, the identification characters displayed on the visible window of the circuit breaker mask in the closing/opening indicator 1 are OFF.

The technical scheme is suitable for the universal circuit breaker operating mechanism, and the safety indicating device is used as a safety indicating device for indicating the energy storage/release state of the circuit breaker operating mechanism and before the circuit breaker is switched on, so that the invalid switching-on operation of the circuit breaker is effectively avoided.
