Description

Technical Field

[0001] The invention belongs to the technical field of counting, and in particular relates to a counting device for an electric circuit breaker. Background Art

[0002] An electrical circuit breaker usually refers to a circuit breaker used in electrical equipment. It refers to a switching device that can close, carry and disconnect current under normal circuit conditions and can close, carry and disconnect current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. When they have serious overloads or short circuits, undervoltage and other faults, they can automatically cut off the circuit. Its function is equivalent to a combination of a fuse switch and an over- and under-temperature relay.

[0003] In order to record the number of times the circuit breaker is opened and closed when in use, a counting device is generally used for recording; since the purpose of closing the circuit breaker is to establish a reliable electrical connection, in order to achieve this, the internal contacts need to be in close contact with sufficient pressure to ensure a low-resistance current path, which usually requires overcoming the preload of the spring, the friction between the contacts, and some possible mechanical resistance, etc., so the handle needs to use a large force to overcome the above resistance when closing the circuit breaker. However, when the circuit breaker trips due to a short circuit, the internal protection device quickly acts to reset the handle. In this process, since the previous limiting force on the handle disappears instantly, the rapid change of the internal mechanical structure of the circuit breaker and the resistance it carries are released through the handle in the form of impact, thereby generating a large impact force and acting on the circuit breaker. If this continues for a long time, the internal components of the circuit breaker will become loose, which not only makes it impossible to ensure the safety of the circuit breaker when in use, but also affects the accuracy of the device when counting, thereby reducing the counting effect and accuracy of the device, and at the same time reducing the service life of the counting device and the circuit breaker, making the device more limited when in use.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) The touch horizontal plate moves under the impact force brought by the handle, which can effectively absorb and disperse the impact force brought by the handle, thereby reducing the damage and injury to the main body caused by the above impact force, and can effectively protect the touch horizontal plate to avoid damage to the handle due to rigid contact with the touch horizontal plate, thereby improving the use effect of the device and the counting accuracy. In addition, the buffering force brought by the positioning spring and the buffer square pad allows the buffer square pad and the positioning spring to absorb the impact force on the handle when they are in a buffering state after being hit, so as to further reduce the impact force caused by the reset of the handle, thereby avoiding excessive impact force on the main body and causing damage to the main body or dislocation of internal parts, thereby further improving the use effect of the device, ensuring the safety of the main body during use, avoiding safety accidents caused by potential threats during use, and avoiding affecting the counting accuracy of the device during use, thereby improving the use effect and accuracy of the device, thereby reducing the limitations of the device during use; (2) The rotating gear meshes with the rotating half-toothed ring to rotate, so that it rotates on the rotating turn box through the half-ring convex block, thereby supporting the rotating half-toothed ring, thereby driving the stop arc cylinder to rotate, and the stop arc cylinder is in the direction of the handle rotation, so that under the action of the stop arc spring and the stop arc column, the stop cross block is driven to move in the direction of the handle, so that the handle and the stop cross block move relative to each other. When the impact force is large enough, the stop cross block contacts the handle, thereby limiting the reset handle to the current position, avoiding the impact force of the handle being too large during the reset, causing damage to the body, thereby improving the service life of the device and the accuracy of counting. At the same time, the rubber pad will contact the handle, thereby increasing the friction between the stop cross block and the handle, avoiding dislocation due to excessive impact when the two are in contact, thereby improving the safety of the device during use. It is worth mentioning that the buffering force brought by the stop arc spring and the rubber pad can reduce the impact force generated when the stop cross block contacts the reset handle, further improving the use effect of the device, avoiding damage to the body caused by the reset of the handle, and reducing the limitations of the device during use; (3) The impact force on the touch horizontal plate acts on the rectangular frame, so that the arc-shaped square rod on the L-shaped square plate slides on the energy-gathering base, so that the rectangular frame and the touch horizontal plate rotate synchronously with the handle after receiving the impact force, and the displacement generated can relieve the impact force caused by the handle when it is reset, so as to effectively disperse the impact force, thereby reducing the damage to the main body, avoiding the risk of damage to the main body and internal components and counting devices caused by excessive impact force when the handle is reset, thereby improving the service life of the device and the counting effect and accuracy; it is worth mentioning that the buffering force brought by the energy-gathering spring can further reduce the damage caused by the handle to the main body, and because the handle is coaxial with the center of the arc-shaped square rod, the reset of the energy-gathering spring can also drive the handle and the touch horizontal plate to reset, waiting for the next use, thereby dispersing the impact force brought by the handle when it is reset to both sides of the main body, avoiding direct contact with the main body to cause damage to it, and reducing the limitations of the device when it is used; (4) When the handle on the main body is reset, due to the large resistance of the handle when closing the switch, the rapid change of the mechanical structure inside the main body, such as the spring, plus the above resistance will be released through the handle in the form of impact, so that the reset rotating handle first contacts the buffer pad on the touch horizontal plate. The existence of the touch horizontal plate can initially limit the reset position of the handle, avoiding the handle directly carrying a strong impact force to reset and causing it to hit the main body, thereby improving the service life of the device; (5) The gas in the guide cylinder enters the gas storage cylinder through the circulation square hole, and the gas directly acts on the pressure block, causing pressure on the pressure block, so that it moves within the gas storage cylinder through the pressure cylinder, so that the pressure spring is in a buffer state, and according to the difference in the above pressure, the pressure spring is in different deformation states, and the force is recorded by the pressure sensor, so that the value of the impact force received by the touch horizontal plate can be recorded, and the staff can monitor it. When the impact force received by the touch horizontal plate is too large, it will be recorded by the pressure sensor, and the staff will be notified, so that they can maintain the main body, avoid hidden damage to the main body during use, and make it difficult to ensure the safety of the device during use, thereby improving the safety of the device during use and reducing the limitations of the device during use; it is worth mentioning that the buffering force brought by the pressure spring and the energy-absorbing elastic plate can further reduce the impact force received by the touch horizontal plate. The existence of multiple buffers can minimize the damage caused by the reset of the handle, thereby improving the use effect and life of the device; (6) When the impact of the handle disappears, the positioning spring that was originally in the buffer state drives the touch horizontal plate to reset and move, so that it can be prepared for the next use, avoiding the need for manual reset by the staff, and reducing the work intensity of the staff; it is worth mentioning that since there are several sensors on the surface of the buffer pad, when the handle is reset, it contacts the sensor, so that the sensor sends a signal to the control unit, so that each tripping of the main body can be counted, avoiding accidents caused by frequent tripping. At the same time, the counting signal received during tripping can be sent to the terminal to notify the staff, so that the use site of the main body can be handled in time, which improves the use effect of the device. In addition, each closing and opening of the main body can be counted through several sensors; (7) When the touch horizontal plate moves downward, the guide column on it moves within the guide cylinder to limit the movement, so that the guide spring is in a buffering state. This not only limits the movement of the touch horizontal plate, but also prevents the touch horizontal plate from being dislocated or shaken due to the excessive impact force brought by the handle when the touch horizontal plate moves, thereby improving the stability of the touch horizontal plate when moving, and improving the use effect of the device; at the same time, the buffering property brought by the guide spring can further reduce the impact force brought by the handle, avoiding damage to the main body or counting equipment caused by the excessive impact force, thereby improving the use effect of the device and the accuracy of counting.

[0020] When a short circuit occurs in the body 1, that is, the electrical circuit breaker during use, the body 1 will be converted from the closed state to the tripped state. It is worth mentioning that when the body 1 is converted from the open state to the closed state, the handle 2 is pushed up to rotate on the body 1 to connect the circuit. However, when the body 1 trips, the handle will automatically jump to the tripped position, so that the handle 2 is reset and rotated, thereby disconnecting the circuit. However, when the handle 2 on the body 1 is reset, due to the large resistance of the handle 2 when closing, the rapid change of the internal mechanical structure of the body 1, such as the spring, plus the above resistance will be released in the form of impact through the handle 2, so that The handle 2 that is rotated to reset first contacts the buffer pad 11 on the touch cross plate 10. The existence of the touch cross plate 10 allows the reset position of the handle 2 to be initially limited, preventing the handle 2 from directly carrying a strong impact force to reset and causing it to hit the body 1, thereby increasing the service life of the body 1.

At the same time, the counting signal received during the trip can be sent to the terminal to notify the staff, so that the use site of the body 1 can be processed in time, which improves the use effect of the device, and each closing and opening of the body 1 can be counted through a plurality of sensors. ;
