[0023] Example

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6This application provides a further detailed description. A modular combined power distribution protection and control device includes a modular power distribution controller 1. A left assembly 2 and a right assembly 3 are mounted on both sides of the modular power distribution controller 1. The left assembly 2 includes a left wall 23, with a first buffer assembly 22 movably disposed on the side of the left wall 23 away from the right assembly 3. The right assembly 3 includes a right wall 34, with a second buffer assembly 31 movably disposed at the end of the right wall 34 away from the left assembly 2. The first buffer assembly 22 and the second buffer assembly 31 are used to buffer the impact received by the modular power distribution controller 1. A first slide rail 21 is fixedly installed on one side of the combined component 3, and a first buffer component 22 is movably located within the first slide rail 21. A second slide rail 32 is fixedly installed on the right wall 34 away from the left combined component 2, and a second buffer component 31 is movably located within the second slide rail 32. The first buffer component 22 includes a movable component 222, and a buffer body 221 is fixedly installed on the top of the movable component 222. The buffer body 221 is made of rubber and is used to protect the top of the modular power distribution controller 1. The movable component 222 includes a wall 2224, and side grooves 222 are formed on both sides of the wall 2224. 3. A first spring column 2221 is fixedly installed in the side groove 2223 of the wall body 2224. A push plate 2222 is fixedly installed at the telescopic end of the first spring column 2221. A front groove 2225 is opened at the end of the wall body 2224 near the modular power distribution and control device 1. Multiple second spring columns 2227 are fixedly installed in the front groove 2225 of the wall body 2224. The first spring column 2221 and the second spring column 2227 are used to support the wall body 2224 in the first slide rail 21. A connecting strip 2226 is provided on the second spring column 2227. Multiple second spring columns 2227 are connected by the connecting strip 2226. The modular power distribution controller 1 is connected as a whole. The left wall 23 has multiple mounting slots 24 on the side near the right assembly 3, and the right wall 34 has multiple mounting parts 33 on the side near the left assembly 2. The mounting parts 33 are adapted to the position and size of the mounting slots 24. The modular power distribution controller 1 includes a housing 11 located inside the left assembly 2 and the right assembly 3. A top cover 12 is fixedly installed on the top of the housing 11. Multiple buttons 14 are installed on one side of the top of the top cover 12. A display 13 is installed at the center of the top cover 12. The housing 11 contains a controller and an operation module. The display 13 is electrically connected to the controller.

[0025] The modular power distribution controller 1 includes several signal acquisition modules and an arc sensor. The signal acquisition modules are used to acquire analog and digital signals in the power distribution system. The signal acquisition modules are connected to a router, the router is connected to a network port module, the arc sensor is connected to an I2C bus expansion module, the network port module and the I2C bus expansion module are connected to the main control unit, the main control unit is connected to the human-machine interface module, the output unit, the communication module and the power supply module, making the modular power distribution controller 1 modular. The modular power distribution controller 1 can be controlled by button 14, and the display 13 is used to display the real-time operating status of the modular power distribution controller 1.

[0026] Since the size and position of the mounting slot 24 and the mounting component 33 are compatible with each other, when the modular combined power distribution protection and control device is assembled, the user only needs to insert the mounting component 33 on the right wall 34 into the mounting slot 24 in the left wall 23, which improves the convenience of assembling the modular combined power distribution protection and control device.

[0027] Since the movable component 222 and the connecting bar 2226 are elastically controlled by the first spring post 2221 and the second spring post 2227, when the wall 2224 needs to enter the first slide rail 21, the user needs to forcefully squeeze the movable component 222 and the connecting bar 2226 before the wall 2224 can enter the first slide rail 21. At this time, the wall 2224 can move freely in the first slide rail 21 and is elastically fixed in real time by the first spring post 2221 and the second spring post 2227.

[0028] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the modular combined power distribution protection and control device are fixed by threads. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the figure. When using the modular combined power distribution protection and control device, the user needs to place the modular power distribution controller 1 inside the left wall 23. Then, the user pushes the right wall 34 towards the left wall 23, causing the mounting part 33 to insert into the mounting slot 24, thus completing the basic assembly of the entire modular combined power distribution protection and control device. Afterwards, the user needs to press the push plate 2222 and the connecting strip 2226, causing the first spring column 2221 and the second spring... The spring column 2227 retracts within the side groove 2223 and the front groove 2225. At this time, the user quickly inserts the wall body 2224 into the first slide rail 21, and inserts the second buffer component 31 into the second slide rail 32 in the same way, so that the rubber buffer body 221 is higher than the modular power distribution monitoring and control device 1. This ensures that when the modular combined power distribution protection and monitoring and control device falls, the rubber buffer body 221 will contact the ground first to cushion the impact. Through the cooperation of the above structure, even if the modular combined power distribution protection and monitoring and control device falls, the first buffer component and the second buffer component can resist the external force, thus improving the safety of the modular combined power distribution protection and monitoring and control device.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
