The right side of each sliding block 26 is fixedly connected to a pull rod 210. The right end of each pull rod 210 extends to the right side of the distribution box 1 and is slidably connected to the distribution box 1. The protection assembly comprises a wire inlet hole 211 arranged on the bottom surface of the distribution box 1. The top surface of the distribution box 1 is provided with a plurality of shunt holes 212. The inner wall of the distribution box 1 is fixedly connected to a fixed block 213. The inner wall of the fixed block 213 is provided with a plurality of electromagnetic release devices 214. The inner wall of the distribution box 1 is fixedly connected to a heat dissipation fin group 215.
[0032] By arranging the protection mechanism 2, the elasticity of the plurality of springs 24 is utilized to drive the top blocks 23 to fix the combed and shunted lines in the bearing blocks 21, so as to avoid dislocation short circuit and other situations caused by disordered lines. When personnel need to remove the lines for maintenance and adjustment, the plurality of wires fixed in the bearing blocks 21 can be loosened by pulling the pull rods 210, without the need of using a tape and other tools. The operation is simple and fast, and it is convenient for personnel to carry out quick protection treatment.
[0033] As shown in Figure 3 , Figure 4 and Figure 6As shown, the switch mechanism 3 includes a box door assembly and a switch assembly, the box door assembly includes a box door 31 hinged on the front of the distribution box 1, the inner wall of the box door 31 is rotatably connected with a rotating shaft 32, the front of the box door 31 is rotatably connected with a rotating handle 33, the back of the rotating handle 33 is fixedly connected with the front end of the rotating shaft 32, the switch assembly includes a torsion spring 34 fixedly connected with the inner wall of the box door 31, the end of the torsion spring 34 is fixedly connected with a clamping block 35, the front of the clamping block 35 is fixedly connected with the end of the rotating shaft 32, the back of the box door 31 is fixedly connected with two second limiting blocks 36, the inner wall of the distribution box 1 is provided with a clamping groove 37, and the inner wall of the clamping groove 37 is slidably connected with the outer wall of the clamping block 35.
[0034] By setting the switch mechanism 3, the elastic deformation of the torsion spring 34 is realized, and the staff only needs to rotate the rotating handle 33 to complete the sealing and switching of the box door 31 and the distribution box 1, which facilitates the staff to quickly open the box door 31 and protect the internal circuit of the distribution box 1. The self-locking sealing structure reduces the influence of the outside on the internal circuit of the distribution box 1, and further improves the practicability of the device.
[0035] One specific application of the embodiment is that the electromagnetic release 214 is a kind of release, which provides short-circuit protection. When the current is large enough, the magnetic field force generated by the current overcomes the counter-force spring to attract the armature and strike the traction rod, thereby driving the mechanism to act and cut off the circuit. In the case that the circuit has no fault, the current passes through the coil of the electromagnetic release, and the magnetic field generated in the coil is weak and cannot attract the iron core or movable part. At this time, the electromagnetic release remains in the "non-triggering" state, and the circuit continues to work normally. The current is transmitted through the circuit breaker. When the current exceeds the set safety value, the coil current in the electromagnetic release increases, generating a stronger magnetic field. This magnetic field will generate enough suction force to attract the iron core or movable part, triggering the release mechanism and disconnecting the contacts of the circuit breaker to cut off the circuit. If a short-circuit fault occurs, the suction force of the electromagnet in the electromagnetic release will also increase rapidly, immediately triggering the release mechanism to quickly disconnect the circuit, preventing the current from further increasing and causing equipment damage or fire.
[0036] By setting up the protective mechanism 2, after the staff opens the box door 31 through the switch mechanism 3, several wires are threaded into the distribution box 1 through the inlet hole 211. After passing through the lower receiving block 21, the staff can comb and separate the wires to align specific wires with the top block 23. By applying a certain force to the wires, the wires are brought into contact with the top block 23. The top block 23 is then pressed into the spring groove 22 according to the arc surface of the top block 23. The top block 23 compresses the spring 24, at which point the top block 23 drives the first limiting block 25 to the guide rod 28. Under the guidance of the limiting mechanism, the wire slides within the groove 27. After releasing the wire, the spring 24 elastically resets, causing the top block 23 to fix the wire within the receiving block 21. One end of the wire is then connected to the electromagnetic trip unit 214. A specific wire is then connected to another point on the electromagnetic trip unit 214. This specific wire passes through the heat sink fin assembly 215 and enters the upper receiving block 21. Similarly, the wire is fixed within the upper receiving block 21 and passes through the diversion hole 212 to complete the power distribution. When the wiring needs adjustment, pulling the lever 210 causes the slider 26 to slide into the reserved position. Inside the groove 29, the slider 26 presses against several first limiting blocks 25 via the groove 27. The first limiting blocks 25 drive the top block 23 to compress several springs 24, causing the wires fixed inside the top blocks 23 to loosen together, eliminating the need to remove them one by one, making it simple and quick. A heat dissipation fin assembly 215 is provided to contact the wires between the electromagnetic trip unit 214 and the upper receiving block 21, absorbing the heat that may be generated by the conducting current. The heat is then conducted into the outside air through the fins on the heat dissipation fin assembly 215, completing the heat dissipation process. The electromagnetic trip unit 214 protects against overload or short circuits in the circuit. It utilizes the elasticity of several springs 24 to move the top block 23 to fix the sorted and divided circuits within the receiving block 21, preventing misalignment and short circuits caused by messy circuits. When personnel need to remove the circuits for maintenance and adjustment, they only need to pull the lever 210 to loosen the wires fixed within the receiving block 21 without the need for cable ties or other tools. This simple and quick operation facilitates rapid protection.
[0037] By setting the switch mechanism 3, the staff can bring the rotating handle 33 and make it rotate, so that the rotating handle 33 drives the clamping block 35 to flip upwards around the rotating shaft 32 to disengage from the clamping groove 37, at this time the clamping block 35 rotates to drive the torsional spring 34 to elastically deform, after the clamping block 35 disengages from the clamping groove 37, pulling the rotating handle 33 drives the box door 31 to flip around the hinge with the distribution box 1, exposing the inside of the distribution box 1, facilitating personnel to maintain or adjust the circuit, wherein two second limit blocks 36 are arranged, which limit the flipping angle of the clamping block 35, realize the elastic deformation of the torsional spring 34, the staff only needs to rotate the rotating handle 33, which can complete the sealing and opening of the box door 31 and the distribution box 1, which is convenient for the staff to quickly open the box door 31 and protect the circuit in the distribution box 1, the self-locking sealing structure reduces the influence of the outside on the circuit in the distribution box 1, and further improves the practicability of the device.
