Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and specifically to a universal circuit breaker with comprehensive perception. Background Art

[0002] With the continuous development of science and technology, a circuit breaker refers to a switching device that can close, carry, and interrupt the current under normal circuit conditions and can also close, carry, and interrupt the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their application scope. The boundary between high and low voltages is relatively blurred, and generally, electrical appliances above 3 kV are called high-voltage electrical appliances. The intelligent universal circuit breaker is applicable to a distribution network with an alternating current of 50 Hz, a rated voltage of 380 V or 660 V, and a rated current of 200 A - 6300 A. It is mainly used to distribute electric energy and protect the line and power supply equipment from the hazards of overload, undervoltage, short circuit, single-phase grounding, etc. This circuit breaker has a variety of intelligent protection functions, can achieve selective protection, with accurate operation, avoid unnecessary power outages, and improve power supply reliability. Under normal conditions, it can be used for the infrequent conversion of the line. Circuit breakers below 1250 A can be used to protect the overload and short circuit of motors in a network with an alternating current of 50 Hz and a voltage of 380 V. Under normal conditions, it can also be used for the infrequent starting of motors. Generally, the universal circuit breaker is used for temporarily repairing abnormal circuits or abnormal circuit breakers in the power grid system where ordinary circuit breakers are located, to avoid the entire power grid being powered off and unusable.

[0003] An existing universal circuit breaker can refer to the Chinese invention patent with the authorization announcement number CN107799366B, which discloses a universal circuit breaker, "including a circuit breaker device, the inner front side of the circuit breaker device is provided with a handle system, the handle system includes a handle shaft, the outer side wall of the handle shaft is symmetrically provided with shaft recesses on the left and right sides, the shaft recess is provided with a fixing ring inside, the fixing ring is connected to the circuit breaker device, the upper sides of the left and right ends of the handle shaft are provided with square grooves, the lower sides of the left and right ends of the handle shaft are provided with triangular grooves, the left and right ends of the handle shaft are symmetrically clamped with control sleeves, and the end of the control sleeve close to the handle shaft is provided with a shaft groove used in conjunction with the handle shaft , a square protrusion is provided on the inner upper side of the shaft groove for use with the square groove. By adjusting the position of the control sleeve, it can be determined whether the device can be opened and closed from the outside, thereby preventing irrelevant personnel from changing the opening and closing state of the circuit breaker. "Although the opening and closing operation can be achieved through the handle system for safety reasons, due to the particularity of the universal circuit breaker, electric sparks or burning may occur when the circuit breaker needs to be switched again, causing damage to the entire circuit breaker during the connection process. On the other hand, after the universal circuit breaker is connected, data collection and analysis are performed only after the ordinary circuit breaker is disconnected, which will lead to inaccurate analysis of the cause of the fault, resulting in subsequent distribution or maintenance, affecting the normal operation of the entire power grid system.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0037] First, with reference to Figures 1-6 , a detailed description will be made of the structural design part of the present invention. A fully - sensing universal circuit breaker includes a protection housing 1, a detachable frame 23, a shunt - action assembly, a controller, and a circuit - breaker assembly 26;

[0038] With reference to Figures 1-2 , the protection housing 1 and the detachable frame 23 are detachably connected. Specifically, it can be set to be installed by magnetic attraction or by plug - in. The detachable frame 23 can be set corresponding to different circuit breakers. According to the model of the circuit breaker to be replaced, the corresponding detachable frame 23 can be selected, so as to ensure that the cable can pass through normally and cover the entire circuit breaker as a replacement target.

[0039] The detachable frame 23 is provided with a receiving groove 25 and a relief hole 24. The receiving groove 25 is used to receive the circuit breaker 30 to be replaced, and the relief hole 24 is used to pass the cable of the circuit breaker 30 to be replaced. Refer to Figure 6 As shown, a contact assembly is formed in the receiving groove 25. The contact assembly includes a plurality of contact tips 19. When the protection shell 1 is covered on the circuit breaker 30 to be replaced, the contact tips 19 are in contact with the contacts on the circuit breaker 30 to be replaced. The contact assembly includes a contact frame body 20, a telescopic rod 21 and an elastic member 22. The contact tips 19 are installed on the telescopic rod 21 and connected to the contact frame body 20 through the elastic member 22. In this way, as long as the positions correspond, the circuit can be connected to form a temporary circuit breaker for intervention work.

[0040] Refer to Figure 6 As shown, the opening operation assembly is used to drive the circuit breaker 30 to be replaced to complete the opening or closing operation. The opening operation assembly includes an opening actuator 17 and an opening crank connecting rod 18. The opening crank connecting rod 18 contacts the opening handle 31 of the circuit breaker 30 to be replaced. When the opening actuator 17 works, it drives the opening crank connecting rod 18 to work to drive the opening handle 31 to act. Refer to Figure 6 As shown, the opening actuator 17 drives the opening crank connecting rod 18 to rotate, and the crank connecting rod swings the opening handle 31 to control the opening and closing of the circuit breaker 30 to be replaced.

[0041] The circuit breaker assembly 26 is coupled to the contact assembly and is used to undertake the function of the circuit breaker after the circuit breaker 30 to be replaced completes the opening operation. The internal working components of the circuit breaker assembly 26 are the same as those of the traditional universal circuit breaker body, and will not be elaborated here. The core element of the present invention is that the corresponding contact assembly can be directly connected to the circuit.

[0042] The controller is coupled to the contact assembly;

[0043] Refer to Figure 5As shown, in a preferred embodiment, arc extinguishing modules 16, sliding rails 13, and operation baffles 27 are provided on both sides of the protective housing 1. The arc extinguishing module 16 includes a number of arc extinguishing fins arranged in parallel. The protective housing 1 is made of a flame-retardant material. The arc extinguishing module 16 and the protective housing 1 are slidably connected through the sliding rail 13. The arc extinguishing module 16 is provided with a locking pin for fixing the arc extinguishing module 16 on the sliding rail 13. The operation baffle 27 is arranged facing the arc extinguishing module 16 and is installed on an operation hole pre-opened on the protective housing 1. The locking pin is inserted into a locking hole pre-opened on the sliding rail 13 through the insertion slider 14. Inserting the locking pin into the locking hole can adjust the distance between the arc extinguishing module 16 and the circuit breaker. The arc extinguishing fins can release the arc as much as possible, improve the arc extinguishing ability, ensure safety, will not cause electric sparks, and will not allow electric sparks to escape to the outside of the housing.

[0044] Referring to Figures 3-4 As shown, in a preferred embodiment, a slot 2 is opened at the top of the protective housing 1. An installation block 3 is installed near the bottom of the slot 2 inside the protective housing 1. A first spring 4 is provided inside the installation block 3. An installation plate 5 is slidably connected to the outside of the installation block 3. Convex grooves 6 are opened on both sides of the protective housing 1, and the convex grooves 6 pass through both sides of the installation plate 5. A second spring 7 is installed inside the convex groove 6. The other end of the second spring 7 is installed with a push plate 8. The other side of the push plate 8 is fixedly connected with a push block 9. A connecting frame 10 is fixedly installed on the side of the protective housing 1. A first threaded rod 11 is threadedly connected inside the connecting frame 10. A pressing block 12 is installed on the side of the first threaded rod 11 close to the protective housing 1. A slot 2 is opened at the top near the front of the protective housing 1, so that installation blocks 3 can be installed on both the left and right sides near the protective housing 1 inside the slot 2. A first spring 4 is installed inside the installation block 3, so that the top of the first spring 4 can push the installation plate 5 to move. The bottom of the installation plate 5 is inserted outside the installation block 3, facilitating the sliding of the installation plate 5. Convex grooves 6 are opened on both sides of the protective housing 1, and the convex grooves 6 pass through both the left and right sides of the installation plate 5. A second spring 7 can be installed inside the convex groove 6 close to one side of the installation plate 5, so that the other end of the second spring 7 can push the push plate 8 and the push block 9 to move. The moving push block 9 can be inserted into the convex groove 6 opened on one side close to the protective housing 1 to fix the position of the installation plate 5. When it is necessary to eject the installation plate 5, by rotating the first threaded rod 11 threadedly connected inside the connecting frame 10, the first threaded rod 11 can drive the pressing block 12 to slide inside the connecting frame 10 when rotating, so that the connecting frame 10 can push the push block 9 to move in the direction of the inside of the protective housing 1, and thus the first spring 4 inside the installation block 3 can push the installation plate 5 to move upward.

[0045] Please refer to Figure 4, the pressing block 12 is slidably connected inside the connecting frame 10. The outer size of the pressing block 12 is the same as the inner size of the convex groove 6 near the side of the protective case 1, and the pressing block 12 and the protective case 1 are on the same straight line. Since the pressing block 12 is slidably connected inside the connecting frame 10, when the first threaded rod 11 rotates, it is convenient for the first threaded rod 11 to push the connecting frame 10 to move. At the same time, since the outer part of the pressing block 12 is the same as the inner size of the convex groove 6 near the protective case 1, the pressing block 12 can push the pushing block 9 to move.

[0046] Please refer to Figure 4 , the shape of the pushing block 9 is a right trapezoid, and the outer part of the pushing block 9 near the protective case 1 is smaller than the outer size near the pushing plate 8. The inclined surface of the pushing block 9 is away from the top of the protective case 1. Since the two ends of the pushing block 9 are of different sizes, when the mounting plate 5 moves downward, it is convenient for the bottom of the pushing block 9 to move into the convex groove 6, so as to facilitate the pushing block 9 to push the pushing plate 8 and the second spring 7.

[0047] Please refer to Figure 5 , sliding rails 13 are provided on both the upper and lower sides inside the protective housing 1. Sliders 14 are slidably connected inside the two sliding rails 13. A moving frame 15 is installed between the two sliders 14. An arc extinguishing module 16 is installed on one side of the moving frame 15 near the outside of the protective case 1. A fixed column 17 is fixedly installed on the other side of the moving frame 15. The fixed column 17 is slidably connected inside the connecting cylinder 18. A third spring 19 is provided inside the connecting cylinder 18. The other end of the connecting cylinder 18 is fixedly installed with a second threaded rod 20. A nut 21 is threadedly connected to the outside of the second threaded rod 20. Symmetrical sliding rails 13 are provided on both the upper and lower sides inside the protective case 1, so that the upper and lower sliding rails 13 can slidably connect the sliders 14, so as to facilitate welding the moving frame 15 between the two sliders 14. Since there are two moving frames 15, a second threaded rod can be inserted into one of the moving frames 15, and the two moving frames 15 can be fixed by screwing in the nut. At the same time, a connecting cylinder 18 is installed at the other end of the second threaded rod 20, and a third spring 19 is installed inside the connecting cylinder 18. One end of the third spring 19 near the inside of the protective case 1 is welded to one end of the fixed column 17 near the inside of the protective case 1, and the fixed column 17 is slidably connected inside the third spring 19. The other end of the fixed column 17 is installed on the side of the other moving frame 15. At the same time, when the third spring 19 contracts, it can drive the two moving frames 15 to clamp the circuit breaker body 22, so as to fix the circuit breaker body 22. On the one hand, it is convenient for the pressing assembly to form a fixed position, and on the other hand, short-distance arc extinguishing can be carried out to improve safety.

[0048] Working principle: When the mounting plate 5 is pushed out during operation, the first threaded rod 11 that is internally threaded in the connecting frame 10 causes the first threaded rod 11 to drive the pressing block 12 to slide inside the connecting frame 10 when rotating, so that the connecting frame 10 can push the push block 9 in the direction of the inner side of the protective case 1, and thus the first spring 4 inside the mounting block 3 can push the mounting plate 5 to move upward; when sealing the protective case 1, the pressing block 12 needs to be rotated out of the convex groove 6, so as to press the mounting plate 5 downward. Due to the shape of the push block 9, the push block 9 can push the push plate 8 to contract the second spring 7. When the push block 9 and the convex groove 6 are in the same plane, the second spring 7 can push the push plate 8 and the push block 9 to move, so that the push block 9 can be inserted into the convex groove 6 on the side away from the mounting plate 5, thereby fixing the position of the mounting plate 5; symmetric sliding rails 13 are provided on the upper and lower sides inside the protective case 1, so that the upper and lower sliding rails 13 can slidably connect the sliders 14, and it is convenient to weld the moving frame 15 between the two sliders 14. Since there are two moving frames 15.

The current collection part is used to collect the current data of the power consumption circuit. The voltage collection part is used to collect the voltage data of the power consumption circuit.

Current collection is completed by connecting a current transformer, voltage collection is completed by connecting a dynamic load, and impedance collection is completed by inputting current.

[0051] The analysis module is configured with an analysis strategy. The analysis strategy generates an operation instruction according to the environmental information and the power consumption information; the analysis module is configured with a power consumption anomaly analysis library.

The analysis module matches the current data, voltage data, and impedance data corresponding to the power consumption anomaly features according to the power consumption information, and the cause trigger factors correspond to the power consumption anomaly features. The analysis strategy includes

[0052] Step S1: Calculate the corresponding environment-induced vector according to the environmental information through a preset environmental evaluation algorithm; the environmental evaluation algorithm includes:

[0055] The environment-induced vector is expressed as (X T , Y RH , Z R ).

[0056] Step S2: Retrieve the corresponding induction recognition network from the pre-configured network matching library according to the environment-induced vector; the induction recognition network includes several cause nodes, each cause node is configured with a cause trigger condition, the cause trigger condition includes several cause trigger elements, and induction connections are formed between the cause nodes, and the induction connections are pre-configured with cause transfer weights. The cause elements corresponding to different induction recognition networks may be different.

The execution module is coupled to the opening operation component and the circuit breaker component, and controls the opening operation component and the circuit breaker component to act through the operation instructions. Specifically, first install the circuit breaker component, then after detecting the corresponding information, generate an operation instruction to control the opening operation component to drive the original circuit breaker to disconnect. It is equivalent to connecting the circuit breaker component to the circuit, and then send the action of the circuit breaker component to the corresponding operation instruction library to implement the operation. After the circuit breaker is connected to the circuit, detect the specific circuit information. After the detection is completed, selectively issue instructions for the circuit breaker component to achieve intelligent control. Then, after all actions are completed, control the opening operation component to perform a closing operation and remove the circuit breaker to complete all detection steps.
