[0002] A circuit breaker is a switch device that can close, carry and disconnect current under normal circuit conditions and close, carry and disconnect 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 scope of use. 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 and undervoltage faults, they can automatically cut off the circuit. Its function is equivalent to the combination of a fuse switch and an over-underheating relay. Moreover, it is generally not necessary to change parts after breaking the fault current.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] For example, see Figures 1 to 6 The utility model provides a circuit breaker protection measurement and control device, including a housing 1, a wiring port 1 26 is provided at the upper end of the housing 1, a wiring port 2 22 is provided at the lower end of the housing 1, a toggle switch 4 is hingedly connected to the surface of the housing 1, a copper coil 25 is provided inside the housing 1, an arc chamber 20 is fixedly connected inside the housing 1, and two openings 6 are provided on the side of the housing 1. The protection measurement and control device also includes a prompt component, which is arranged in the housing 1, and the prompt component includes:

[0032] A double copper sheet 21, the right side of the double copper sheet 21 is fixedly connected to the inside of the second wiring port 22, a sleeve 27 is sleeved on one end of the double copper sheet 21 away from the second wiring port 22, a paddle 24 is also arranged inside the sleeve 27, the side of the paddle 24 is abutted and fixed to the inner wall of the toggle switch 4, a fixing frame 33 is also fixedly connected to the inner wall of the housing 1, a sliding rod 23 is slidably connected to the side of the fixing frame 33, and the end of the sliding rod 23 is abutted against the side of the paddle 24;

[0033] A movable column 28, the surface of which slides through the inner wall of the outer shell 1, the end face of the movable column 28 abuts against the outer surface of the kit 27, the surface of the movable column 28 is also hinged with a curved rod 30, the other end of the curved rod 30 is slidably connected to a sliding block 31, the surface of the sliding block 31 is slidably connected to a sliding frame 29, the outer surface of the sliding frame 29 is fixedly connected to the inner wall of the outer shell 1, the side of the sliding block 31 is also fixedly connected to a prompt column 32, the surface of the prompt column 32 slides through the inner wall of the outer shell 1.

[0034] In this embodiment, when the circuit breaker is disconnected due to short circuit or overload during use, the prompt column 32 will have different movement states;

[0035] When a short circuit occurs, a large amount of current will be generated, which will cause a large magnetic field to be generated in the copper coil 25, thereby attracting the sliding rod 23 to move in the direction of the copper coil. During the movement, the paddle 24 will be pressed to drive the toggle switch 4 to rotate. During the movement, the paddle 24 will not drive the kit 27 to move, which will further cause the circuit breaker to trip.

[0036] When overloaded, the double copper sheet 21 heats up due to overload, so that the double copper sheet 21 is completely bent, and the sleeve 27 is moved by the bending of the double copper sheet 21, so that the circuit breaker is tripped, and the sleeve 27 moves, so that the moving column 28 moves, so that the bent rod 30 deflects, and the sliding block 31 slides in the sliding frame 29, so that the prompt column 32 is pushed out;

[0037] The arrangement of the prompt component ensures that the prompt column 32 will not be pushed out when the circuit breaker is tripped due to a short circuit. When the circuit breaker is tripped due to an overload, the prompt column 32 will be pushed out so that the prompt column 32 will have different movement modes during the use of the circuit breaker, allowing the user to more intuitively know the reason for the circuit breaker tripping, thereby making subsequent maintenance more convenient.

[0038] Embodiment 2, based on the above embodiment, includes a connection assembly in this embodiment, the connection assembly is arranged on the housing 1, the connection assembly includes a dustproof cylinder 19, the end of the dustproof cylinder 19 is fixedly connected to the surface of the housing 1, the end of the dustproof cylinder 19 is also fixedly connected to a fixing column 17, the surface of the fixing column 17 is rotatably connected to a dustproof plate 16, the interior of the dustproof cylinder 19 is also slidably connected to a screw 18, and the other end of the screw 18 is threadedly connected to the surface of the wiring port 1 26;

[0040] In this embodiment, the clamping plate 2 5 is pulled to put the wire into the opening 6, and the clamping plate 2 5 is loosened. The clamping plate 2 5 will be reset under the action of the spring 7 and clamp the wire. Then the dust plate 16 is rotated to make the screw 18 in the dust cylinder 19 leak out, and then the screw 18 is twisted to fix the wire head on the wiring port 1 26 or the wiring port 2 22, so as to complete the connection between the circuit breaker and the circuit.

[0041] The setting of the connection assembly completely wraps the connection ends of the circuit breaker through the clamping plate 2 5 and the clamping plate 1 9, as well as the dustproof plate 16, thereby reducing the contact between the inside of the circuit breaker and the outside world, further preventing the circuit breaker from being affected by external moisture or dust, and making the circuit breaker more stable during use.

[0042] Embodiment 3, based on the above embodiment, this embodiment includes a mounting assembly, the mounting assembly is arranged on the housing 1, and the mounting assembly includes:

[0043] A second fixing frame 15, the surface of the second fixing frame 15 is fixedly connected to the surface of the housing 1, the inner wall of the second fixing frame 15 is rotatably connected to a bidirectional threaded rod 12, the upper end surface of the bidirectional threaded rod 12 is fixedly connected to a knob 14, and the threaded surface of the bidirectional threaded rod 12 is threadedly connected to a clamping block 13;

[0044] The fixing plate 2 has a back surface fixedly connected with a padding block 11, and a surface of the fixing plate 2 is also provided with a rivet groove 3. The fixing plate 2 is used for being installed on a wall.

[0045] In this embodiment, after fixing the second fixing plate 2 on the wall, the knob 14 is turned to rotate the bidirectional threaded rod 12, and the rotation of the bidirectional threaded rod 12 drives the two clamping blocks 13 to approach each other, further clamping the upper and lower ends of the second fixing plate 2, thereby completing the fixing of the circuit breaker;
