Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker with a protection function. Background Art

[0002] A circuit breaker is a switch 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 are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances.

[0003] In order to protect the existing circuit breaker, it is generally set inside a rectangular box. The existing rectangular box is generally a self-locking cabinet or a rectangular cover fixed on the side of the fixed plate by screws. In this way, when manual power-off operation is required, it is necessary to open and disassemble the protection box and the protection cover, resulting in the inability to timely power-off operation. In addition, the side switch of the circuit breaker is generally made of plastic, which may be aged, damaged and broken after long-term use, making the switch fail during manual power-off, resulting in the inability to quickly and effectively cut off the power. For this reason, we propose a circuit breaker with a protection function. Utility Model Content

[0014] Beneficial Effects

[0015] The utility model provides a circuit breaker with a protective function. It has the following beneficial effects:

[0016] (1) The circuit breaker with a protective function is provided with a toggle module. When the power is manually cut off, the installation rod is directly pulled to slide on the protective cover so that the squeezing rod is squeezed on the side of the connecting block. The connecting block is toggled so that the circuit breaker module switch is closed. Conversely, the installation rod can squeeze the circuit breaker module switch to open it. The supporting spring elastically supports the movable block so that it can slide and drive the squeezing rod to elastically fit on the side of the connecting block. In this way, the power-off operation can be directly performed without disassembling the protective cover, and the power-on operation can be performed after the power is cut off, so that the power-off operation can be performed in time.

[0017] (2) The circuit breaker with protection function is provided with a safety module. When the switch of the manual power-off circuit breaker module is damaged, the installation rod is pulled to the bottom side so that the circuit breaker plate is positioned between the auxiliary plates. The installation rod is pressed so that the circuit breaker plate is squeezed between the auxiliary plates. The first terminal block and the second terminal block are pulled apart, and the connecting line is disconnected, completing the power-off operation of the line. This further ensures the disconnection of the line and completes the effective and timely power-off operation. BRIEF DESCRIPTION OF THE DRAWINGS

The reinforcement block 23 reinforces the circuit breaker plate 22.

[0032] The working principle of this utility model:

[0033] When manual power off is required in use, in the initial state, the card block 15 is carded in the card slot 14 so that the mounting rod 6 is fitted to the side position of the protective cover 2. At this time, the slide block 7 is located at one side of the slide slot 5. When in use, the mounting rod 6 is pulled to make the card block 15 disengage from the card slot 14 and away from the protective cover 2. The mounting rod 6 is pushed downward to make the slide block 7 slide inside the slide slot 5. The synchronous mounting plate 8 drives the extrusion rod 13 to move. The extrusion rod 13 contacts the side of the connecting block 4 and squeezes so that the switch on the side of the circuit breaker module 3 is turned off. When the extrusion rod 13 is squeezed on the side of the connecting block 4, the extrusion rod 13 is relatively squeezed. The extrusion causes the movable block 10 to slide on the side of the constraint rod 11, and the support spring 12 elastically supports the movable block 10 so that the extrusion rod 13 fits the side position of the connecting block 4 to complete the manual power-off operation. Conversely, the installation rod 6 drives the extrusion rod 13 to move upward, and the extrusion rod 13 is squeezed on the side of the connecting block 4 to drive it upward to turn on the switch of the circuit breaker module 3. The extrusion rod 13 continues to squeeze the connecting block 4. When the force becomes larger, the movable block 10 squeezes the support spring 12 to deform and slide, so that the extrusion rod 13 is separated from the side of the connecting block 4, and the installation rod 6 slides to the top and presses the card block 15 to be clamped in the card slot 14 and fixed.

[0034] During manual power-off, when the side switch of the circuit breaker module 3 is damaged and the power cannot be cut off, the mounting rod 6 slides downward to the lowest position at the same time. At this time, the circuit breaker plate 22 is located between the auxiliary plates 16, and the auxiliary plate 16 is pressed close to the side position of the protective cover 2. The card block 15 is carded in the corresponding position of the card slot 14, and the circuit breaker plate 22 is squeezed between the auxiliary plates 16. The auxiliary plates 16 are squeezed and move away from each other, so that the first terminal block 19 and the second terminal block 20 are detached. At this time, the connecting line 21 is disconnected, and the power-off operation of the route is completed.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
