[0022] 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 of 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.

[0023] The following is combined with Figure 1-6 This application is described in further detail.

[0024] An alarm-capable power distribution equipment includes a cabinet body 12, a cabinet door 3 and a distribution device 13. The cabinet door 3 is rotatably arranged on the cabinet body 12. A mounting plate 9 is fixedly arranged in the cabinet body 12. The distribution device 13 is arranged on the mounting plate 9. A protection switch 1 is fixedly arranged on the mounting plate 9. The protection switch 1 is electrically connected to the distribution device 13. The distribution device 13 and the protection switch 1 use a power supply 1.

[0025] A temperature sensor 2 is fixedly arranged on the mounting plate 9, and the temperature sensor 2 is electrically connected to the protection switch 1. An alarm light 11 is fixedly arranged on the top of the cabinet 12, and the alarm light 11 is provided with a buzzer and a light bulb. The alarm light 11 can emit a buzzer sound and light up a warning when in use.

[0026] The alarm light 11 is electrically connected to the temperature sensor 2. The temperature sensor 2 and the alarm light 11 use power supply 2. By setting power supply 1 and power supply 2, the use effect of the distribution cabinet can be improved. When the distribution device 13 is powered off due to a malfunction, the alarm light 11 can be used normally, which is convenient for issuing alarm instructions to the staff.

[0027] The cabinet 12 is provided with an installation opening, and two installation openings are arranged on the cabinet 12, and the two installation openings are respectively arranged on both sides of the cabinet 12. A fixing plate 10 is fixedly arranged on the installation opening, and the fixing plate 10 is a hollow structure. A cylinder 14 is fixedly arranged in the fixing plate 10, and the cylinder 14, the temperature sensor 2, and the alarm light 11 all use power supply 2.

[0028] The fixed plate 10 is sleeved with a movable plate 8, one end of the movable plate 8 is located inside the fixed plate 10, and the other end of the fixed plate 10 abuts against the bottom of the cabinet 12. The telescopic shaft of the cylinder 14 is fixedly connected to one end of the movable plate 8 close to the fixed plate 10, and the cylinder 14 is electrically connected to the temperature sensor 2.

[0029] A limit plate 7 is fixedly arranged on the installation opening, and a plurality of limit plates 7 are arranged on the installation opening. The limit plates 7 abut against the movable plate 8. When the movable plate 8 moves up and down under the action of the cylinder 14, the limit plates 7 can stabilize the movement of the movable plate 8. A tightening strip is fixedly arranged on one side of the movable plate 8 away from the fixed plate 10, and the tightening strip abuts against the cabinet 12.

[0030] The cabinet 12 is provided with a heat dissipation hole 4 at the bottom, and a plurality of heat dissipation holes 4 are provided at the bottom of the cabinet 12, and the heat dissipation holes 4 play a role in heat dissipation. The cabinet 12 is fixedly connected with a mounting frame 6 at the bottom, and a grid plate 5 is fixedly provided on the mounting frame 6, and a plurality of grid plates 5 are provided on the mounting frame 6. Under the action of the heat dissipation holes 4 and the grid plates 5, the air circulation between the cabinet 12 and the air is enhanced, and the heat dissipation effect is also enhanced.

[0031] The implementation principle of this embodiment is: when the temperature in the cabinet 12 exceeds the threshold value set by the temperature sensor 2, the protection switch 1 disconnects the power supply of the distribution device 13, and the distribution device 13 is powered off. Because the distribution device 13 and the alarm light 11 use two power supplies, after the distribution device 13 is powered off, the alarm light 11 and the cylinder 14 can be used normally. At this time, the alarm light 11 emits a buzzing sound and lights up to warn the staff to come and deal with the alarm situation. At the same time, the cylinder 14 starts, and the movable plate 8 moves upward under the action of the cylinder 14. The installation port is opened, and the circulation speed between the cabinet 12 and the air is accelerated, which accelerates the loss of heat in the cabinet 12 and performs preliminary cooling of the cabinet 12. After that, wait for the staff to come for further inspection and processing, so as to achieve the effect of making the distribution cabinet have a high temperature alarm function and improving the safe use of the distribution cabinet.
