Abstract
Description
Technical Field
[0001] This utility model relates to the field of leakage current protection technology, and in particular to a fast power-off protection switch. Background Technology
[0002] In industrial and civil power distribution systems, distribution boxes are the core equipment for power distribution and control. Under normal circumstances, when electrical safety accidents such as leakage, short circuit or electric shock occur, the leakage current protection device in the distribution box should immediately cut off the power supply to prevent the accident from escalating.
[0003] However, when an electric shock occurs, the current forms a circuit between the human body and the ground, causing the residual current device (RCD) that should immediately cut off the power to fail to respond. In this case, it is necessary to manually cut off the power supply in the distribution box. However, the current power supplies are all installed inside the distribution box and are protected by external shields, which makes it inconvenient to cut off the power in an emergency.
[0004] Therefore, a fast power-off protection switch needs to be designed. Utility Model Content
[0005] To overcome the inability to immediately cut off power to the distribution box, this utility model provides a fast power-off protection switch.
[0006] Technical Solution: A fast-break protection switch includes a distribution box, a power-off box, transparent glass, a mounting rack, a window breaker, a main switch, a support plate, a button, a battery compartment, a connecting rod, an electromagnet, a sleeve rod, a guide rod, and a bracket. The power-off box is fixedly installed in the middle of the left side of the distribution box. Transparent glass is fixedly installed in the front of the power-off box. A mounting rack is fixedly connected to the middle of the left end face of the power-off box, and a window breaker is placed on the mounting rack for breaking the transparent glass in an emergency. A main switch is located in the lower left side of the distribution box for controlling all switches in the distribution box. The power-on status is as follows: a support plate is fixedly installed in the middle of the power-off box; a button is fixedly installed on the upper part of the front face of the support plate; a battery compartment is fixedly installed on the lower part of the front face of the support plate; a connecting rod is rotatably connected between the power-off box and the distribution box; two electromagnets are fixedly installed on the rear side of the power-off box; a sleeve rod is fixedly connected to the right end of the connecting rod; the sleeve rod covers the main switch; two guide rods are fixedly connected to the lower end of the sleeve rod; a bracket is fixedly installed in the lower part of the distribution box; the lower part of the guide rod slides through the bracket; the button is electrically connected to the electromagnet.
[0007] In a preferred embodiment of this utility model, the connecting rod has a lever structure.
[0008] In a preferred embodiment of this utility model, a warning sign is provided on the transparent glass.
[0009] In a preferred embodiment of this invention, the battery in the battery compartment is powered by two electromagnets.
[0010] In a preferred embodiment of this utility model, the electromagnet is located directly below the connecting rod, and when the electromagnet is energized, the movable end lifts the connecting rod.
[0011] In a preferred embodiment of this utility model, an alarm is also included. An alarm is fixedly installed on the upper end of the distribution box. The alarm is electrically connected to the button. When the button is pressed, the alarm sounds an alarm.
[0012] Compared with the prior art, the present invention has the following advantages: The present invention can quickly start the power-off procedure by breaking the transparent glass and pressing the button, and use the electromagnet to drive the linkage rod to turn down the main switch, thereby realizing the power-off of the distribution box, achieving the effect of conveniently cutting off the power supply in the distribution box in an emergency.

[0018] Example: A fast-acting power-off protection switch, such as Figures 1-4As shown, the system includes a distribution box 1, a power disconnect box 2, transparent glass 4, a shelf 5, a window breaker 6, a main switch 7, a support plate 8, a button 9, a battery compartment 10, a connecting rod 11, an electromagnet 12, a sleeve rod 13, a guide rod 14, and a bracket 15. The power disconnect box 2 is screwed onto the middle left side of the distribution box 1. Transparent glass 4 is fixedly installed on the front side inside the power disconnect box 2. A shelf 5 is fixedly attached to the middle left end face of the power disconnect box 2, and a window breaker 6 is placed on the shelf 5 for emergency breaking of the transparent glass 4. A main switch 7 is located on the lower left side inside the distribution box 1 to control the energization of all switches inside the distribution box 1. A support plate 8 is fixedly installed in the middle inside the power disconnect box 2. A button 9 is fixedly installed on the upper front surface of the support plate 8, and a button 9 is fixedly installed on the lower front surface of the support plate 8. A battery compartment 10 is fixedly provided. A connecting rod 11 is rotatably connected between the power disconnect box 2 and the distribution box 1. The connecting rod 11 passes through the power disconnect box 2 and the distribution box 1. Two electromagnets 12 are installed on the rear side of the power disconnect box 2 by screws. A sleeve rod 13 is fixedly connected to the right end of the connecting rod 11. The sleeve rod 13 covers the main switch 7. Two guide rods 14 are fixedly connected to the lower end of the sleeve rod 13. A bracket 15 is fixedly provided in the lower part of the distribution box 1. The lower part of the guide rods 14 slides through the bracket 15. The button 9 is electrically connected to the electromagnets 12. The connecting rod 11 has a lever structure. A warning sign is provided on the transparent glass 4. The battery in the battery compartment 10 powers the two electromagnets 12. The electromagnets 12 are located directly below the connecting rod 11. When the electromagnets 12 are energized, the movable end lifts the connecting rod 11.
[0019] like Figure 1 As shown, it also includes an alarm 3. The alarm 3 is installed on the upper end of the distribution box 1 by screws. The alarm 3 is electrically connected to the button 9. When the button 9 is pressed, the alarm 3 will sound an alarm.
[0020] The device is installed inside the power disconnect box 2 on the left side of the distribution box 1. A transparent glass 4 serves as a protective barrier on the front of the power disconnect box 2, preventing accidental activation and facilitating observation of the internal status. The transparent glass 4 has clear warning signs printed on its surface, reminding non-professionals not to operate it. In the event of a sudden electrical accident, if the leakage current protection device fails to trip in time, the emergency power disconnect procedure must be manually activated. At this time, the operator takes out the window breaker 6 placed on the rack 5 and strikes the transparent glass 4 forcefully to break it, exposing the operating area of the button 9 inside. After the operator presses button 9, the alarm 3 is activated simultaneously, emitting an audible and visual alarm to alert on-site personnel that the power distribution system has entered an emergency power disconnect state and to notify relevant personnel for further handling. Simultaneously, button 9... The electrical signal is transmitted to the independent power supply system in the battery compartment 10 to provide power to the two electromagnets 12. After the electromagnets 12 are energized, their movable ends extend upwards and lift the connecting rod 11 located directly above them. The connecting rod 11 has a lever structure. After being lifted by the electromagnets 12, the other end moves downwards, causing the sleeve rod 13 fixed to it to move downwards together. The sleeve rod 13 was originally sleeved on the main switch 7. As the sleeve rod 13 moves downwards, it also pulls the main switch 7 down, putting the main switch 7 in the open state. The lower part of the sleeve rod 13 is connected to two guide rods 14. The guide rods 14 pass through the bracket 15 fixed in the lower part of the distribution box 1, which plays a guiding and limiting role, ensuring that the sleeve rod 13 moves vertically and preventing deviation or jamming, thereby realizing the emergency power cut-off of the distribution box 1.
