DETAILED DESCRIPTION

[0021] 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.

[0022] Example 1: Please refer to Figure 1-2 A power distribution switch housing that is easy to disassemble includes a power distribution cabinet 1, in which placement slots 12 are vertically arranged, and the placement slots 12 are opened outward. A bottom magnet 121 is provided at the center of the surface corresponding to the inner wall opening, and is laid on the entire surface. Magnetic field magnets 122 are provided on the upper and lower surfaces of the inner wall of the placement slot 12, and the magnetic properties are inconsistent to form a vertical magnetic field. An air switch 13 is installed in the placement slot 12, and an electromagnet 132 corresponding to the position of the bottom magnet 121 is provided on the back of the air switch 13, and the shape of the back of the air switch 13 fits the shape of the inside of the placement slot 12. The electromagnet 132 is connected to a conductor, and a circuit switch 131 is provided to control the on and off of the circuit of the electromagnet 132.

[0023] Furthermore, the position of the conductor corresponds to the magnetic field magnet 122, and when the air switch 13 is located in the placement slot 12 and slides left and right, the magnetic field formed by the magnetic field magnet 122 can be cut to form an electric current. The magnetism generated by the electromagnet 132 is the same as the bottom magnet 121, which will generate a repulsive force to push the air switch 13 out. When the maintenance is completed, the circuit switch 131 is disconnected and the air switch 13 is inserted back vertically. Due to the influence of the magnetic force of the bottom magnet 121 and the fact that the electromagnet 132 does not generate magnetism, the bottom magnet 121 can attract it, so that the air switch 13 is fixed in the placement slot 12, so as to achieve the purpose of quickly disassembling and assembling the air switch 13, which greatly shortens the maintenance time of the staff and does not require traditional screw installation, which is more convenient and quick.

[0024] The shell of the air switch 13 between the electromagnet 132 and the bottom magnet 121 is made of a metal material that can be attracted by a magnet. When the electromagnet 132 does not generate magnetism, the air switch can be installed in the placement slot 12 more easily without falling.

[0025] The conductor is specifically a conductor loop 133. The conductor is made into a spring shape so that the path for cutting the magnetic flux lines is longer, which can increase the size of the induced current.

[0026] There is a distance of at least 2 cm between the bottom magnet 121 and the magnetic field magnet 122 to reduce the impact of the bottom magnet 121 on the magnetic field generated by the magnetic field magnet 122, and there is a distance of at least 5 cm between each air switch 13 to ensure that each air switch 13 has sufficient sliding distance. At the same time, each air switch can have good heat dissipation to avoid heat accumulation.

[0027] Cabinet doors 11 are provided on both sides of the power distribution cabinet 1. When maintenance is completed, the cabinet doors can be closed to prevent dust from entering and causing damage to the air switch 13.

[0028] Example 2: Please refer to Figure 2-3 A power distribution switch housing that is easy to disassemble includes a power distribution cabinet 1, in which placement slots 12 are vertically arranged, and the placement slots 12 are opened outward. A bottom magnet 121 is provided at the center of the surface corresponding to the inner wall opening, and is laid on the entire surface. Magnetic field magnets 122 are provided on the upper and lower surfaces of the inner wall of the placement slot 12, and the magnetic properties are inconsistent to form a vertical magnetic field. An air switch 13 is installed in the placement slot 12, and an electromagnet 132 corresponding to the position of the bottom magnet 121 is provided on the back of the air switch 13, and the shape of the back of the air switch 13 fits the shape of the inside of the placement slot 12. The electromagnet 132 is connected to a conductor, and a circuit switch 131 is provided to control the on and off of the circuit of the electromagnet 132.

[0029] Furthermore, the position of the conductor corresponds to the magnetic field magnet 122, and when the air switch 13 is located in the placement slot 12 and slides left and right, the magnetic field formed by the magnetic field magnet 122 can be cut to form an electric current. The magnetism generated by the electromagnet 132 is the same as the bottom magnet 121, which will generate a repulsive force to push the air switch 13 out. When the maintenance is completed, the circuit switch 131 is disconnected and the air switch 13 is inserted back vertically. Due to the influence of the magnetic force of the bottom magnet 121 and the fact that the electromagnet 132 does not generate magnetism, the bottom magnet 121 can attract it, so that the air switch 13 is fixed in the placement slot 12, so as to achieve the purpose of quickly disassembling and assembling the air switch 13, which greatly shortens the maintenance time of the staff and does not require traditional screw installation, which is more convenient and quick.

[0030] The shell of the air switch 13 between the electromagnet 132 and the bottom magnet 121 is made of a metal material that can be attracted by a magnet. When the electromagnet 132 does not generate magnetism, the air switch can be installed in the placement slot 12 more easily without falling.

[0031] The conductor is specifically a conductor loop 133. The conductor is made into a spring shape so that the path for cutting the magnetic flux lines is longer, which can increase the size of the induced current.

[0032] There is a distance of at least 2 cm between the bottom magnet 121 and the magnetic field magnet 122 to reduce the impact of the bottom magnet 121 on the magnetic field generated by the magnetic field magnet 122, and there is a distance of at least 5 cm between each air switch 13 to ensure that each air switch 13 has sufficient sliding distance. At the same time, each air switch can have good heat dissipation to avoid heat accumulation.

[0033] See also Figure 4 The distribution cabinet 1 is provided with a single-side cabinet door 11, and a cabinet door lock 2 is provided on the other side. The cabinet door lock 2 is provided with an infrared rangefinder 22 capable of emitting infrared rays outward, and a rotatable buckle 21. A glass plate 111 is provided on the side of the cabinet door 11, and the position thereof corresponds to the infrared rangefinder 22 when the cabinet door is closed. The glass plate 111 can transmit the infrared light emitted by the infrared rangefinder 22, and the buckle 21 can fasten and close the cabinet door 11 through the glass plate 111. The cabinet door 11 can be opened and closed by rotating the buckle 21, and the operation is simple. At the same time, the switch state of the cabinet door can be detected by the infrared rangefinder 22, so as to avoid forgetting to close the cabinet door 11 when the maintenance is completed.

[0034] When the infrared rangefinder 22 detects that the buckle 21 is fastened to block, it can control the circuit switch 131 in the air switch 13 to disconnect, to prevent the circuit switch 131 from being forgotten to disconnect after the maintenance is completed and the cabinet door 11 is closed. The electromagnet 132 in the air switch 13 may be energized due to partial vibration, causing it to pop out and cause damage.

[0035] Working principle: When the maintenance personnel need to disassemble and repair the air switch 13, they open the cabinet door 11 and close the circuit switch 131 to connect the internal circuit connected to it. Because magnetic field magnets 122 are provided on the upper and lower surfaces of the inner side of the placement slot 12 for installing the air switch 13, and a bottom magnet 121 is also provided at the corresponding position on the back of the air switch 13, by sliding the air switch 13 left and right, a conductor loop 133 is provided inside the air switch 13 at the position corresponding to the magnetic field magnet 122. Because the magnetic field magnets 122 on the upper and lower sides can form a vertical magnetic field, the conductor loop 133 can be slid left and right. Cutting the magnetic flux lines generates electricity to energize the electromagnet 132. The magnetism generated by the electromagnet 132 is the same as that of the bottom magnet 121, which will generate a repulsive force to push the air switch 13 out. When the inspection is completed, the circuit switch 131 is disconnected and the air switch 13 is inserted back vertically. Due to the magnetic influence of the bottom magnet 121 and the fact that the electromagnet 132 does not generate magnetism, the bottom magnet 121 can attract it, so that the air switch 13 is fixed in the placement slot 12, so as to achieve the purpose of quickly disassembling and assembling the air switch 13, which greatly shortens the inspection time of the staff and does not require traditional screw installation, which is more convenient and quick.
