Description

Technical Field

[0001] The invention relates to a remote-controlled intelligent circuit breaker, belonging to the technical field of circuit breakers. Background Art

[0002] Among the existing power supply network terminals, traditional circuit breakers are still the most widely used. Some smart grid terminals also use remote-controlled intelligent circuit breakers. In addition to realizing the basic functions of fault tripping protection such as short circuit and overload, remote-controlled intelligent circuit breakers also need to realize real-time monitoring of power consumption, collection of power consumption information, remote control of circuit breakers, and opening and closing of circuit breakers and other intelligent functions.

[0003] At present, most of the remote-controlled intelligent circuit breakers are passively broken and remotely monitored during use, and rarely actively broken. Since the circuit breaker is prone to failure after multiple circuit breaking, it needs to be inspected, maintained and replaced, and the general remote-controlled intelligent circuit breaker does not have the function of recording the number of circuit breaking times; and the arc extinguishing chamber inside the general circuit breaker is mostly extinguished by injecting insulating oil, and the insulating oil will enter the interior when used for a long time. At the same time, it will contain some carbonized and aged substances, which makes the oil conductive and easily cause fire hazards in the event of a short circuit. When replacing the insulating oil, the entire shell needs to be disassembled, which is very inconvenient; and the general remote-controlled intelligent circuit breaker does not have the function of location indication and maintenance record. Summary of the invention

When the connecting rod is disengaged due to a short circuit and the knife is separated, the connecting rod starts to slide, and the second rack drives the second gear to mesh and rotate. When it is due to an active short circuit, the connecting rod slides under the action of the top rod, the second rack drives the first gear to rotate, and the first gear drives the transmission wheel to rotate, and the transmission wheel drives the second gear to mesh and transmit, so that the magnet rod on the gear shaft of the second gear passes through the Hall element in the electromagnetic counter once, completing a circuit breaking count, which is convenient for supervision, maintenance and replacement of the circuit breaker, and strictly controlling the service life of the circuit breaker.

A controller 19 is installed at the bottom of the overcurrent release 10 and the undervoltage release 11. The signal of the controller 19 is MAM-330. A wireless receiver 20 is installed on one side of the controller 19. The model of the wireless receiver 20 is YS-53. A wireless transmitter 21 is installed at one end of the wireless receiver 20. The model of the wireless transmitter 21 is PT2272-M4. A GPS module 22 is installed at one end of the wireless transmitter 21. The model of the GPS module is K20B. A speaker 24 is installed on one end of the GPS module 22, and a TF card slot 23 is installed at the bottom of the speaker 24. A display screen 25 is installed on the surface of the shell 1 at a position corresponding to the controller 19, and a control button 26 is installed on one side of the display screen 25. The opening and closing motor 8, the electromagnetic counter 16, the wireless receiver 20, the wireless transmitter 21, the GPS module 22, the TF card slot 23 and the display screen 25 are all electrically connected to the control button 26, and the control button 26 is electrically connected to the external power supply.

[0016] In this embodiment: a magnet rod 29 is installed on the side of the gear shaft close to the second gear 14, and a Hall element is installed inside the electromagnetic counter 16, which can sense the magnetic field change of the magnet. When the magnet rod 29 swings, each time it swings through the Hall element, the counter will record a number, which can record the number of circuit breakers due to active circuit breaking or short circuit protection, so as to facilitate supervision, repair and replacement of the circuit breaker, and strictly control the service life of the circuit breaker; The first gear 13, the transmission wheel 28 and the second gear 14 are all equal in size, ensuring that the first rack 12 drives the first gear 13 to rotate, the first gear 13 drives the transmission wheel 28 to rotate, and the transmission wheel 28 drives the second gear 14 to rotate in the same direction and torque as the second rack 15 drives the second gear 14; An oil inlet pipe 17 is installed at the top of the housing 1, and an oil outlet pipe 18 is installed at the bottom of the housing 1. Sealing covers are threadedly connected to the outer sides of the oil inlet pipe 17 and the oil outlet pipe 18. The sealing covers can be opened and insulating oil can be injected into the oil inlet pipe 17 to squeeze out the original insulating oil, thereby avoiding the impurity of the oil caused by free carbonization, aging or moisture in the insulating oil, and greatly avoiding the hidden danger of fire caused by short circuit; The shortest distance between the push rod 6 and the baffle 5 is equal to the shortest distance between the baffle 5 and the inner wall of the housing 1, ensuring that when a short circuit occurs, when the lock hook rod 9 is lifted due to the action of the overcurrent release 10 and the undervoltage release 11, when the connecting rod 2 is pulled back under the action of the tension spring 4, the movement of the connecting rod 2 will not be hindered due to the contact between the push rod 6 and the baffle 5; A protective cover 27 is installed on the outside of the display screen 25 and the control button 26. The top of the protective cover 27 is hingedly connected to the shell 1. The protective cover 27 prevents the control button 26 from being knocked over by a small object and causing a circuit breaker. It also has waterproof and dustproof functions, making it more convenient to use.

[0017] Working principle: When the present invention is used, when the circuit is broken, the inductive coil on the overcurrent releaser 10 will generate a magnetic field, adsorbing the upper armature, causing the armature to swing, and lifting the lock hook rod 9, so that the lock hook on the connecting rod 2 is separated from the lock hook rod 9. At this time, the connecting rod 2 is retracted due to the action of the tension spring 4, and the knife 3 is separated from the circuit to complete the circuit breaking. When the connecting rod 2 moves to the left, the second rack 15 will drive the second gear 14 to rotate, and the magnet rod 29 on the gear shaft of the second gear 14 will swing in the electromagnetic counter 16 and pass through the Hall element once. At the same time, the wireless transmitter 21 will send the circuit breaker status and the positioning information of the GPS module to the external host. After the maintenance personnel repair and reclose the switch, after the connecting rod 2 is reset, the magnet rod 29 will pass through the Hall element once again to complete a cycle. At this time, the counter will record a number and record it in the TF card in the TF card slot 23. Then the maintenance personnel can also make maintenance records by operating the button 26 after maintenance. When active circuit breaking is required, the control is sent to the control through the external host. The controller 19 sends a command, which is received by the wireless receiver 20. At the same time, the opening and closing motor 8 drives the eccentric wheel 7 to rotate and squeezes the push rod 6, so that the push rod 6 lifts the baffle 5, drives the connecting rod 2 to move, and at the same time the knife 3 is separated from the line, and the tension spring 4 is extended. At this time, the first rack 12 drives the first gear 13 to rotate, and the first gear 13 drives the transmission wheel 28 to rotate, and the transmission wheel 28 drives the second gear 14 to rotate through the gear shaft, so that the magnet rod 29 passes through the Hall element once. After closing the switch, the magnet rod 29 passes through the Hall element once again, completing a cycle and counting once. In addition, the sealing covers on the oil inlet pipe 17 and the oil outlet pipe 18 can be opened regularly, and insulating oil can be injected into the oil inlet pipe 17 to squeeze out the original insulating oil from the oil outlet pipe, so as to avoid the tedious cleaning of the insulating oil by disassembling the housing 1. The oil quality can be quickly replaced, the carbonization, aging substances and moisture in the oil can be reduced, and the conductive substances can be avoided, which greatly reduces the hidden danger of fire caused by short circuit, and the whole work process ends. The contents not described in detail in this specification belong to the prior art known to professionals in this field.
