Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and in particular to a circuit breaker indicating device and a circuit breaker using the same. Background Art

[0002] At present, most specifications of small circuit breakers in the industry do not have the function of indicating the opening and closing status. Some specifications have the above indication function, but there are problems of inaccurate indication status or complex indication structure. The usual method for such circuit breakers with a single closing and opening indication function is to set a rotating structure at the swinging position of the moving contact, and drive the rotating structure to indicate the closing and opening status through the swinging of the moving contact.

[0003] However, the above method of setting a pendant on the moving contact has the following defects:

[0004] 1. During the operation of the product, the structural parts and the contacts are indirectly connected, which can easily cause the failure of the indicating structural parts, resulting in the inability of the indicating structural parts to correctly indicate the closing and opening states of the contacts, and the reliability is not high;

[0005] 2. In addition, the above-mentioned indicating device only has the indicating function of closing and opening. If a short circuit protection opening occurs in the line, it is very dangerous if it is not distinguished whether it is a fault trip or a manual operation opening, and an inappropriate closing action is taken;

[0006] Comparative Document 1: CN109979787A discloses a leakage circuit breaker indicator and a leakage circuit breaker, wherein the leakage circuit breaker indicator comprises: a reset button, which is movably mounted on a housing, and has an initial position located inside the housing, and an action position extending from the top of the housing when leakage occurs; a connector, which is respectively connected to the reset button and the operating mechanism, and when in the action position, the reset button drives the connector to drive the operating mechanism to open the switch; a first biasing member, which is connected to the reset button and applies a biasing force to the reset button to move toward the action position; a locking assembly, which locks the reset button when the reset button is in the initial position, and is released from the lock of the reset button when leakage occurs, and the reset button is driven to move by the first biasing member. The scheme of Comparative Document 1 cannot clearly indicate the current state of the circuit breaker, and is relatively simple.

[0007] Comparative Document 2: CN105070600A discloses a fault status indication device for a circuit breaker, including a contact group, a transmission assembly and an indication assembly installed in a housing. The contact group realizes a normally open contact group and a normally closed contact group. The transmission assembly acts on the contact support to realize different opening and closing states of the contact group through the contact support. The indication assembly indicates the fault state, and the indication assembly is linked with the circuit breaker to respond to the fault and make corresponding status indications. Due to the connection between the structural member and the contact in the scheme of Comparative Document 2, the failure of the indicating structural member may be caused. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a circuit breaker indicating device with a simple structure and three state indicating functions, and a circuit breaker using the device.

[0009] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0010] The present invention provides a circuit breaker indicating device, comprising a manual indicator and a fault indicator, wherein the manual indicator comprises a display color plane, a rotating shaft and an external force application plate, wherein the display color plane is arranged at the top of the manual indicator, and the external force application plate is welded between the display color plane and the rotating shaft; the fault indicator comprises a fault display color plane, a rotating shaft bottom plate and a first circular arc groove, wherein the fault display color plane is arranged at the top of the fault indicator, and the first circular arc groove is fixedly connected to the fault display color plane through the rotating shaft bottom plate;

[0011] The display color plane is divided into an opening display color plane and a closing color display plane;

[0012] The rotating shaft base plate includes a rotating shaft;

[0013] The circuit breaker indicating device also includes a spring;

[0014] A movable buckle position is provided between the manual indicator and the fault indicator;

[0015] The rotating shaft is movably nested in the rotating axis, the manual indicator and the fault indicator can rotate relative to each other, and the two are fixed by spring elastic force, so that the fault display color plane is located below the display color plane;

[0016] The tripping swing shaft of the circuit breaker passes through the first arc groove, and the tripping swing shaft performs corresponding actions therein, and the circuit breaker indicating device performs corresponding swings, so that the corresponding opening display color plane and closing display color plane are respectively displayed on the window; when the external force application plate is hit, the manual indicator is rotated by force and the spring is compressed, so that the fault indicator is rotated out and the fault display color plane is exposed.

[0017] When the tripping swing shaft of the circuit breaker stays at the lower end position of the first arc groove, the color display window reveals the closing display color plane. When the circuit breaker handle is switched from the closing state to the opening state, the tripping swing shaft will press against the left wall of the first arc groove, and the display color plane will rotate to the right. At this time, the spring buckles the manual indicator so that the fault indicator will not be rotated out. When the circuit breaker handle is pushed to the opening position, the tripping swing shaft stops.

[0018] When the tripping swing shaft of the circuit breaker stays at the upper end position of the first arc groove, the color display window exposes the opening display color plane. When the circuit breaker handle is switched from the opening state to the closing state, the tripping swing shaft will press against the right side wall of the first arc groove. At this time, the display color plane will swing to the left. At this time, the spring also holds the manual indicator, so that the fault display color plane of the fault indicator will not be rotated out until the circuit breaker handle is pushed to the closing position, at which time the tripping swing shaft stops.

[0019] When the line is broken or overloaded, the lock of the circuit breaker will apply an external force inward. This external force will break the locking balance between the trip buckle and the lock buckle of the circuit breaker. At this time, the trip buckle will rotate rapidly clockwise along its own axis under the action of the spring. During the rotation process, the convex pendulum of the circuit breaker trip buckle will hit the external force application plate under the shielding groove of the fault indicator display plane. During the resetting process of the circuit breaker handle, due to the impact force of the convex pendulum structure of the trip buckle, the circuit breaker indicating device is forced to rotate rapidly and compress the spring. The magnitude of this impact force is related to the working torque of the circuit breaker handle spring. Force is related. Since the working torque of the circuit breaker handle spring is much greater than the reset holding force of the spring, the spring movable foot is compressed and the fault indicator is rotated out. During the rotation, the movable buckle between the manual indicator and the fault indicator is buckled. At this time, since the manual indicator is stopped and the fault indicator is in a screwed-out state, the fault display color plane is exposed. At this time, the reaction force of the spring is not enough to push the manual indicator and the buckle is released. At this time, the fault display color plane of the fault display is just below the color display window of the circuit breaker housing.

[0020] Furthermore, the display color plane is an arc surface, and the closing display color plane and the opening display color plane respectively occupy half of the arc surface, the left plane of the display color plane is the closing display color plane, and the right plane of the display color plane is the opening display color plane. The arc surface prevents the display color plane from being collided with other mechanisms when swinging.

[0021] Furthermore, the manual indicator further comprises a rotating swing arm, a shielding groove bottom surface and a buckle. The rotating swing arm is exerted with force by the tripping swing shaft in a fault state, so that the manual indicator rotates, the fault indicator is rotated back to the bottom of the manual indicator, and the circuit breaker indicating device completes the reset.

[0022] Furthermore, the bottom surface of the shielding groove is an arc surface with the same center as the display color plane, and the bottom surface of the shielding groove is fixedly welded below the display color plane, and a shielding groove is formed in the middle, and the shielding groove can completely accommodate the fault display color plane. The shielding groove will shield the fault display color plane when the switch is open or closed, and only the open display color plane and the closed display color plane will be exposed in the circuit breaker window.

[0023] Furthermore, the shielding groove is closed at one end where the bottom surface of the shielding groove is welded to the display color plane, and the other ends are open, so that the fault display color plane forms as little friction and resistance as possible with other structures in the shielding groove, and the overall structure is more complete and beautiful.

[0024] Furthermore, the buckle can be plastically deformed, so that the circuit breaker indicating device can maintain the fault state and complete the reset.

[0025] Furthermore, the rotating swing arm includes a hollow cylindrical structure and a swing arm structure, the swing arm structure is fixedly welded to the hollow cylindrical structure, and the hollow cylindrical structure is fixedly welded to the lower end of the external force application plate.

[0026] Furthermore, the rotating shaft is fixedly nested in the hollow cylindrical structure.

[0027] Furthermore, the fault display color plane is an arc-shaped surface having the same center as the display color plane, so that the fault display color plane is located in the shielding groove and is not affected by friction.

[0028] Furthermore, a spring socket, a second circular arc groove and an open annular structure are also provided on the bottom plate of the rotating shaft, and the second circular arc groove is correspondingly arranged in the active area of ​​the buckle under the fault state; one end of the spring is inserted into the spring socket, and the other end is wrapped around the rotation axis of the fault indicator and then extends out from the open annular structure, and the circuit breaker device is fixed by elastic force.

[0029] Furthermore, a semicircular protrusion structure is provided at the position corresponding to the buckle in the second arc groove, and the semicircular protrusion structure and the buckle are movable buckles between the manual indicator and the fault indicator; when the buckle is buckled on the semicircular protrusion structure, a resistance is formed, so that the circuit breaker indicating device maintains the current state.

[0030] Furthermore, a rotating swing arm active area is provided at a cross section of one side of the first arc groove. In a fault state, the rotating swing arm will be rotated into the rotating swing shaft active area, and the movable tripping swing shaft will apply external force to the rotating swing shaft and drive the entire circuit breaker indicating device to complete reset.

[0031] The present invention also provides a circuit breaker adopting the above-mentioned circuit breaker indicating device, comprising a trip button, a metal connecting rod, a circuit breaker handle and a circuit breaker housing, wherein the trip button swing shaft is movably connected to the trip button, the trip button is movably linked to the metal connecting rod, the metal connecting rod is movably linked to the circuit breaker handle, and a color display window is provided on the circuit breaker housing.

[0032] Furthermore, the trip buckle is provided with a convex pendulum structure, which will buckle the lock buckle during normal opening and closing, and will be released from the locked state with the lock buckle when a fault occurs, and hit the external force application plate of the circuit breaker indicating device.

[0033] Furthermore, the circuit breaker further comprises a lock, a moving contact and a stationary contact, wherein the lock is fixedly hinged with the moving contact. In the normal closing and opening state, the moving and stationary contacts are in magnetic contact, and when a fault occurs, the moving and stationary contacts quickly pop open, and the lock and the moving contact swing at the same time, so that the locking balance of the lock and the tripping lock is broken.

[0034] When the line is broken or overloaded, the lock of the circuit breaker will apply an external force inward. This external force will break the locking balance between the trip buckle and the lock buckle of the circuit breaker. At this time, the trip buckle will rotate rapidly clockwise along its own axis under the action of the spring. During the rotation process, the convex pendulum of the circuit breaker trip buckle will hit the external force application plate under the shielding groove of the fault indicator display plane. During the resetting process of the circuit breaker handle, due to the impact force of the convex pendulum structure of the trip buckle, the circuit breaker indicating device is forced to rotate rapidly and compress the spring. The magnitude of this impact force is related to the working torque of the circuit breaker handle spring. The force is much greater than the resetting holding force of the spring. At this time, the spring movable foot is compressed and the fault indicator is rotated out. During the rotation process, the buckle in the manual indicator and the semicircular protrusion structure of the second arc groove in the fault indicator form a buckle position. The buckle is blocked by the semicircular protrusion structure and undergoes plastic deformation. At this time, since the manual indicator is stopped and the fault indicator is in a rotated-out state, the fault display color plane is exposed. At this time, the reaction force of the spring is not enough to push the manual indicator and push the buckle position to release. At this time, the fault display color plane of the fault display is just below the color display window of the circuit breaker housing.

[0035] When the circuit breaker indicating device is already in a fault state, the spring has the maximum energy storage, and the fault indicator is maintained by the buckle position. When the circuit breaker is closed, the tripping swing shaft will move downward against the right side wall of the first arc groove, and the tripping swing shaft will apply force to the rotating swing arm. Because the force applied by the tripping swing shaft is a manual external force, under the action of this external force, the rotating swing arm will overcome the locking force of the buckle position, and the buckle will deform again. Once the buckle position is separated, the manual indicator will be reset under the reverse force of the spring. At this time, the fault display color plane is rotated back into the shielding groove, the fault display color plane will be covered by the display color plane, the circuit breaker color display window will reveal the fault display color plane, and the circuit breaker indicating device completes the reset action.

[0036] The beneficial effects of the present invention are:

The circuit breaker indication device provided by the present invention has three status indication functions, namely, manual opening status, manual closing status and fault opening status; it can effectively distinguish between manual opening and fault opening of the product, which is convenient for product operation and maintenance personnel to distinguish and perform corresponding processing operations according to the status indication;

[0038] 2. The circuit breaker indicating device provided by the present invention is an independent mechanical structure, which is simple and convenient to install and does not involve changes to the overall structure of the circuit breaker. BRIEF DESCRIPTION OF THE DRAWINGS

[0083] like Figure 3 As shown, the present invention also provides a circuit breaker 1 using the above-mentioned circuit breaker indicating device 1.2, including a trip button 1.5, a metal connecting rod 1.4, a circuit breaker handle 1.3 and a circuit breaker housing 1.1, the trip button swing shaft 1.6 is movably connected to the trip button 1.5, the trip button 1.5 is movably linked to the metal connecting rod 1.4, the metal connecting rod 1.4 is movably linked to the circuit breaker handle 1.3, and a color display window is provided on the circuit breaker housing 1.1.

[0084] Preferably, a convex pendulum structure is provided on the jump buckle 1.5.

[0085] Preferably, the circuit breaker further comprises a lock buckle 1.5 and a moving contact 1.9, and the lock buckle 1.8 and the moving contact 1.9 are fixedly hinged together.

[0086] The structure of the embodiment of the present invention can realize the indication of manual closing and opening indication status and line fault tripping status under safety maintenance.

[0087] 1. In the manual closing state, the circuit breaker indicator device 1.2 is exposed in the window of the circuit breaker housing 1.1 and the display color is yellow, which represents a warning function and indicates that the circuit under the load end of the circuit breaker is in a normal power supply state;

[0088] 2. Manual opening state: The circuit breaker indicator device 1.2 is exposed in the window of the circuit breaker housing 1.1 and the display color is green, indicating that the load end is disconnected and the lower end can be inspected and operated;

[0089] 3. Fault tripping state: The circuit breaker indicator device 1.2 is exposed in the window of the circuit breaker housing 1.1 and displays the color of red and the word "fault", indicating that closing is prohibited. It means that a short circuit or overload fault occurs at the load end. The load end user needs to check the line fault and eliminate the fault before manual closing;

[0090] In the normal manual closing and opening process of the indicating device in this embodiment, the indication color of the window 1.1 of the circuit breaker housing only switches and displays correspondingly between yellow and green, but when a fault occurs, the window of the circuit breaker indicating device 1.2 will display red. After the fault is eliminated, the circuit breaker is manually closed again, and the window of the circuit breaker indicating device 1.2 will return to yellow. At the next manual opening, when the normal manual opening and closing is restored, the window of the circuit breaker indicating device 1.2 will restore the normal manual opening and closing corresponding display color strategy.

[0091] like Fig.10 As shown, when the tripping swing shaft 1.6 stays at the lower end position of the first arc groove 1.23e, the color display window corresponds to the closing display color-yellow window indication. When the circuit breaker handle 1.3 is switched from the closing state to the opening state, the tripping swing shaft 1.6 will support the left side wall of the first arc groove 1.23e, along the Fig.10 When the circuit breaker handle 1.3 is pushed to the opening position, the tripping swing shaft 1.6 stops.

[0092] like Fig.11 As shown, the jump lock pendulum shaft 1.6 stays at Fig.11When the circuit breaker handle 1.3 is switched from the open state to the closed state, the tripping swing shaft 1.6 will support the right side wall of the first circular arc groove 1.23e, as shown in the figure. Fig. 9 As shown in the figure, the right shear head moves downward, and the color plane will swing to the left. At this time, the spring 1.22 also holds the manual indicator 1.21, and the fault display surface of the fault indicator 1.23 will not be rotated out. Until the circuit breaker handle 1.3 is pushed to the closing position, the tripping swing shaft 1.6 stops and is positioned as shown in the figure. Fig.10 Position shown.

[0093] like Fig.12 As shown in the figure, when the line is broken or overloaded, the lock 1.8 will Fig.12 An external force f is applied at the arrow position shown. After the external force is applied, the locking balance between the trip buckle 1.5 and the lock buckle 1.8 will be broken. At this time, the trip buckle 1.5 will rotate rapidly clockwise along its own axis under the action of the spring. During the rotation process, the convex pendulum of the trip buckle 1.5 will hit the external force application point 1.21d of the fault indicator 1.23. During the resetting process of the circuit breaker handle 1.3, due to the impact force of the convex pendulum of the trip buckle 1.5, the circuit breaker indicating device 1.2 is forced to rotate rapidly and compress the spring 1.22. The magnitude of this impact force is similar to that of the circuit breaker handle 1.3. .3 The working torque of the spring is related. Since the working torque of the spring of the circuit breaker handle 1.2 is much greater than the reset holding force of the spring 1.22, the movable foot of the spring 1.22 is compressed, and the fault indicator 1.23 is rotated out. During the rotation, the semicircular ring structure 1.21e in the manual indicator 1.21 and the semicircular protruding structure 1.23b of the second arc groove 1.23a in the fault indicator 1.23 form a buckle, and plastic deformation occurs after being blocked. At this time, since the manual indicator 1.21 is stopped, it is fixed as shown in FIG. Fig.14 Position, at this time, the manual indicator 1.21 is also in the state of being rotated out, exposing the fault display color plane. At this time, the reaction force of the spring 1.22 is not enough to push the manual indicator 1.21 and push the buckle to release. At this time, the fault display color plane of the fault display 1.23 is just below the shell status display window, exposing the red display color and displaying the word "fault", indicating that the tripping at this time is due to overload or short circuit fault in the line, and the fault needs to be eliminated before manual closing can be performed.

[0094] When the line short circuit or overload fault is eliminated, push the handle to close or open the switch, and the product status display should return to normal yellow and green color switching. At this time, the above indicator combination needs to have a reset structure.

[0095] like Fig.13As shown, at this time, the spring 1.22 has the maximum energy storage, and the fault indicator 1.23 is affected by the buckle position to achieve state retention. When the circuit breaker is closed, the tripping swing shaft 1.6 will push against the right side wall of the first arc groove 1.23e and move downward. Fig.16 Position, the jump lock pendulum shaft 1.6 will apply force to the rotating swing arm 1.21g, because the force applied by the jump lock pendulum shaft 1.6 is a manual external force. Under the action of this external force, the rotating swing arm 1.21g will overcome the above-mentioned buckle locking force, and the protrusion of this buckle will deform again. Once the buckle is separated, the manual indicator 1.21 will be reset under the reverse force of the spring 1.22. Fig.18 As shown, at this time, the shielding groove 1.21c will rotate the fault display color 1.23f plane of the fault indicator 1.23 back into the shielding groove, the fault display color plane 1.23f will be covered by the display color plane, the circuit breaker housing status display window will restore the manual closing yellow display, and the circuit breaker indicating device 1.2 will complete the reset action.

[0096] The specific embodiments described herein are merely examples of the spirit of the present invention. A person skilled in the art of the present invention may make various modifications or additions to the specific embodiments described or replace them in a similar manner, but this will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
