Description

Technical Field

[0001] The utility model relates to the technical field of distribution box protection, in particular to a distribution box protection device with an insulating effect. Background Art

[0002] With the widespread use of electricity in modern society, the safety of distribution boxes, as key equipment for power distribution and control, is of paramount importance. However, traditional distribution boxes currently have some safety hazards during use. On the one hand, in the distribution box, electrical components such as circuit breakers may malfunction during operation due to various reasons, such as overload, short circuit, etc., which may cause fire. Once a fire occurs, if it cannot be isolated in a timely and effective manner, the fire can easily spread to the surrounding area, posing a serious threat to the entire distribution box and surrounding equipment and the environment, and may even cause major safety accidents such as explosions and electric shocks, resulting in equipment damage and property loss. On the other hand, the mounting plate of a traditional distribution box is usually directly connected to the box body. During the operation of electrical equipment, if leakage occurs, the current can easily be transmitted to the box body, increasing the risk of electric shock to users. Moreover, the outer shell of the distribution box made of ordinary materials often does not have good insulation and fire resistance, and cannot provide effective protection for users in unexpected situations.

[0003] After searching, the applicant found that a Chinese patent disclosed "a distribution box protection device with an insulating effect", and its publication (announcement) number is "CN221328399U". The patent mainly uses a box body, and both sides of the bottom of the box body are fixedly connected to the card blocks, and the bottom of the inner cavity is fixedly connected to a pair of positioning seats, and a mounting plate is installed on the positioning seat. Positioning holes are opened at the four corners of the surface of the mounting plate. The positioning blocks are fixedly connected on both sides of the bottom, and several threaded barrels are fixedly connected to the rear side of the inner cavity of the box body. The inner threads of the threaded barrels are connected to bolts. An insulating cover is installed on the outside of the box body, and a box door is installed on the front side of the box body. The front end of the box door is fixedly connected to a pair of fixing frames, and an insulating handle is installed on the box door. The utility model can isolate the box body and the box door from the outside world through the insulating cover and the insulating handle respectively, so as to play the role of insulation protection, thereby effectively preventing the staff from accidentally touching the live box body and box door and causing electric shock, and the electronic components related to the distribution box can be integrated and installed through the mounting plate. When the mounting plate is damaged, it can be disassembled and removed for inspection and replacement. However, this device cannot effectively protect the circuit in an emergency. For this reason, we propose a distribution box protection device with an insulating effect. Utility Model Content

[0029] Working principle:

[0030] First, when the circuit breaker 37 installed in the protective shell 31 on the mounting plate 3 is working normally, the isolation cover 33 supported by the movable leg 32 is in the open state. When the circuit breaker 37 catches fire due to an accident, the high temperature will cause the fuse rod 35 supporting the isolation cover 33 to melt. At this time, the spring 36 that has been in a stretched state will shrink rapidly, pulling the isolation cover 33 down to cover the burning circuit breaker 37 and achieve isolation. This can effectively prevent the fire from spreading to the surrounding area and reduce the impact of the fire on the entire distribution box and surrounding equipment and the environment. The threat of the environment is reduced, the probability of major safety accidents such as explosions and electric shocks caused by fire is reduced, and the degree of damage to equipment is reduced to protect property safety. The bottom plate 2 is fixed to the mounting plate 3 by screws. A rubber spacer 21 is installed between the bottom plate 2 and the mounting plate 3. The rubber spacer 21 has good insulation performance and can effectively prevent the current from being transmitted from the mounting plate 3 to the box body 1, greatly reducing the risk of electric shock. A plastic shell 4 is installed around the mounting plate 3. The plastic shell 4 can be made of polytetrafluoroethylene, which has excellent insulation performance. The performance is good, which can reliably block the conduction of current and prevent users from electric shock accidents. At the same time, it also has excellent fireproof properties. In the event of a fire, it can effectively prevent the spread of fire, providing double protection for the safe operation of the distribution box. The rotating block 41 on the outer wall of the plastic shell 4 enables the first switch door 42 to be flexibly opened and closed, which is convenient for maintenance and operation of the equipment on the mounting plate 3. The block on the first switch door 42 cooperates with the rotating buckle 43 on the top of the plastic shell 4 to ensure the stability of the first switch door 42 in the closed state. The upper and lower hinges 12 on the outermost side of the box body 1 are connected to the second switch door 13. The handle 14 on the surface of the second switch door 13 facilitates users to open and close the distribution box and perform overall operation and maintenance of the internal equipment. The grounding connector 11 installed inside the box body 1 is fixed with a nut and can lead the leakage current in the circuit to the ground, further ensuring the personal safety of users and the normal operation of equipment. The outlet at the bottom end of the box body 1 is used to lead out wires and connect external equipment to realize the power distribution function of the distribution box. At this point, the entire workflow is completed.
