Description

Technical Field

[0001] This utility model belongs to the field of distribution box technology, specifically an outdoor leakage protection distribution box with a quick-release lightning protection module. Background Technology

[0002] With the increasing demands for safety and stability in modern power systems, outdoor leakage protection distribution boxes, as core equipment for ensuring power distribution and electricity safety, are widely used in urban power grids, new energy power plants, and industrial facilities. To protect distribution equipment from lightning strikes, surge protection modules (SPDs) are typically installed inside the distribution boxes to discharge surge currents. Currently, multiple sets of bolts are the mainstream installation method for SPDs in distribution boxes. However, this method has significant drawbacks in actual operation and maintenance: when the SPD needs to be disassembled and replaced due to aging, failure, or preventative maintenance, operators must disassemble multiple sets of bolts one by one, a tedious and time-consuming process. Therefore, we propose a quick-release outdoor leakage protection distribution box with a surge protection module. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 A lightning protection module quick-release outdoor leakage protection distribution box includes a leakage protection distribution box 1. An electrical mounting frame 11 is fixedly installed inside the leakage protection distribution box 1. A pressure frame 13 is placed on the front side of the electrical mounting frame 11, and connecting posts 14 are evenly fixed on the rear side of the pressure frame 13. A pressure ring 15 is fixedly installed on the outer ring of the connecting posts 14. Insertion holes are evenly opened through the front side of the electrical mounting frame 11, and the rear end of the connecting posts 14 is inserted into the insertion holes. Two sets of slots are evenly opened on the upper and lower sides of the electrical mounting frame 11. A set of pull plates 12 is placed on both the upper and lower sides of the electrical mounting frame 11. Two sets of pins 16 are evenly fixed on the opposite sides of the two sets of pull plates 12. Anti-slip sleeves 17 are fixedly installed on the outer ring of the pins 16, and high-strength springs 18 are placed on the outer ring of the anti-slip sleeves 17. A locking hole is opened through the outer wall of the connecting posts 14. The pins 16 and the anti-slip sleeves... 17 is inserted into the slot and locking hole. The high-strength spring 18 uses its own rebound force to drive the pull plate 12 to be fixed on the electrical mounting bracket 11. In turn, the pull plate 12 can drive the pin 16 to be inserted into the slot of the electrical mounting bracket 11 and the locking hole of the connecting post 14, thereby fixing the position of the connecting post 14 and the pressure frame 13 on the outside of the connecting post 14. The anti-slip sleeve 17 can improve the friction between the pin 16 and the electrical mounting bracket 11 and the connecting post 14, thereby improving the insertion stability of the pin 16 and improving the reliability of the device. The electrical mounting bracket 11 has two sets of annular grooves evenly opened on the upper and lower sides respectively. The annular grooves are located on the outer ring of the slot, and the insertion hole is connected to the slot. The bottom of the high-strength spring 18 is fixedly set in the annular groove, and the top of the high-strength spring 18 is fixedly set in the bottom of the pull plate 12.

[0020] A surge protection module 2 is installed on the front side of the leakage protection distribution box 1. A pressure frame 13 is fitted onto the outer front part of the surge protection module 2. The rear end of the connecting post 14 passes through the bolt hole of the surge protection module 2 and is inserted into the socket of the electrical mounting bracket 11. The pressure frame 13 presses the front side of the surge protection module 2, and four sets of pressure rings 15 press the four corners of the surge protection module 2. The connecting post 14 passes through the bolt hole of the surge protection module 2 and is inserted into the socket of the electrical mounting bracket 11. The connecting post 14 positions the surge protection module 2, so that the surge protection module 2 can be stably fixed on the electrical mounting bracket 11. The pressure rings 15 are evenly distributed at the four corners on the front side of the surge protection module 2. Both the pressure rings 15 and the pressure frame 13 are in contact with the outer side of the surge protection module 2.

[0021] Working principle: Both the leakage protection distribution box 1 and the lightning protection module 2 are existing equipment, and their working principles will not be described in detail here. A high-strength spring 18 uses its own rebound force to drive the pull plate 12 to be fixed on the electrical mounting bracket 11. This allows the pull plate 12 to drive the pin 16 to be inserted into the slot of the electrical mounting bracket 11 and the locking hole of the connecting post 14, thus fixing the position of the connecting post 14. This, in turn, fixes the position of the pressure frame 13 on the outside of the connecting post 14. The anti-slip sleeve 17 can improve the contact between the pin 16 and the electrical mounting bracket. The friction between the mounting bracket 11 and the connecting post 14 is used to improve the insertion stability of the pin 16, thereby improving the reliability of the device. The front side of the lightning protection module 2 is pressed by the pressure frame 13, and the four corners of the lightning protection module 2 are pressed by the four sets of pressure rings 15. The connecting post 14 passes through the bolt hole of the lightning protection module 2 and is inserted into the socket of the electrical mounting bracket 11. The connecting post 14 positions the lightning protection module 2, so that the lightning protection module 2 can be stably fixed on the electrical mounting bracket 11.

[0022] By pulling the pull plate 12 outward to separate the pin 16 and anti-slip sleeve 17 from the connecting post 14, the pressure frame 13, connecting post 14 and pressure ring 15 can be moved forward to separate from the lightning protection module 2. Then the lightning protection module 2 can be removed from the electrical mounting bracket 11, thereby improving the disassembly efficiency of the lightning protection module 2.
