Description

Technical Field

[0001] The utility model relates to the technical field of rapid power switching, in particular to a digital rapid power switching switch device. Background Art

[0002] A substation is a place in the power system that transforms voltage and current, receives and distributes electrical energy. In the power network, many users have high requirements for power supply reliability. Once a power outage occurs in some units, it will cause significant economic losses and even casualties. Therefore, the power transformer control cabinet in the power supply system needs to have two power supplies: a main power supply and a backup power supply. When the main power supply fails, the backup power supply must be immediately put into use to restore power, that is, a main and auxiliary dual-circuit power supply is used to ensure its stable and reliable operation. In order to achieve this goal, it is necessary to manually or automatically switch between the main power supply and the backup power supply through a dual power switching mechanism, that is, to control the connection and disconnection of the two power supplies.

[0003] The Digital Fast Transfer Switching Device is an advanced power control device that uses digital control technology and a high-speed switching mechanism. It is designed to achieve fast, safe, and reliable automatic switching between two or more power sources. This device is mainly used in critical systems that require uninterruptible power supply (UPS), such as data centers, hospitals, communication base stations, and industrial production lines. It ensures that in the event of a main power failure, it can instantly switch to the backup power source to avoid power outages. With its high degree of automation, intelligence, and rapid response capabilities, the Digital Fast Transfer Switching Device has become an indispensable key component in modern uninterruptible power supply systems.

[0004] In the prior art, digital power fast switching switch devices are equipped with a dedicated bracket or mounting base for fixing on a wall, distribution cabinet or other mounting surface. The base is usually designed with mounting holes for fixing with screws or bolts. Although it meets the use requirements to a certain extent, the installation method using a dedicated bracket usually requires direct installation on the wall or cabinet using screws, bolts or other fixings, which is difficult to be compatible with existing electrical installation systems or standard accessories, limiting the interchangeability of the equipment and the flexibility of system integration. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are: the device is used for fast switching of digital power supply;

[0014] 1. The upper and lower sides of the DIN rail are clamped by the set limit slots, and the front and rear sides of the DIN rail are clamped between the mounting plate, fixed stopper, and movable stopper to fix the main structure on one side of the DIN rail. By controlling the position of the movable stopper on one side of the mounting plate, the main structure can be quickly installed and removed. During this process, the position of the movable stopper can be quickly changed and fixed by the cooperation between the card block, elastic block, and slot. When the card block is fixed inside the bottom slot, the installation mechanism can be detached from the DIN rail. When the card block is fixed inside the top slot, the installation mechanism can lock the DIN rail to complete the fixation. The spring allows the staff to move the elastic block to make the card block fall off from the slot. The movable stopper can quickly rebound and buckle one side of the DIN rail, making installation convenient. When the mounting mechanism is in the unlocked state through the guide wheel, it can be hung on the top of the DIN rail and flexibly moved left and right to facilitate the adjustment of the position of the main structure. The cooperation between the aluminum mounting plate and the heat dissipation slot facilitates heat dissipation of the main structure, ensuring long-term stable operation of the main structure.

[0015] 2. The air switch is set up to provide overload and short-circuit protection for the main power supply and the backup power supply respectively while connecting them. Even if one group of power supplies fails, the other group can be protected independently to prevent the failure from expanding, ensuring the safe operation of the system. The solid-state switch is responsible for quickly switching between the main power supply and the backup power supply, and the staff can quickly switch the main structure to manual mode or automatic mode by adjusting the switch, which improves the stability and reliability of the system, gives operational flexibility and the ability to respond to special situations, and ensures the efficient and safe operation of the power supply system. The power switching is manually controlled by the switching handle, and the human-computer interaction component is connected through the interactive component wiring terminal, which is convenient for users to operate and monitor the equipment through the human-computer interaction component.

[0025] Several guide wheels 211 are rotatably mounted inside the limiting groove 202 at the top of the mounting plate 201;

[0026] The mounting plate 201 is made of aluminum alloy, and a heat dissipation slot 212 is defined inside the mounting plate 201 .

[0027] The specific implementation method is as follows: the upper and lower sides of the DIN rail 3 are clamped by the limit slot 202, and the front and rear sides of the DIN rail 3 are clamped between the mounting plate 201, the fixed stopper 203, and the movable stopper 204, so as to fix the main structure 1 on one side of the DIN rail 3. By controlling the position of the movable stopper 204 on one side of the mounting plate 201, the main structure 1 can be quickly installed and removed. In this process, the movable stopper can be quickly changed and fixed by cooperating between the clamping block 205, the elastic block 206, and the clamping slot 207. When the block 205 is fixed in the bottom slot 207, the mounting mechanism 2 can be separated from the DIN rail 3. When the block 205 is fixed in the top slot 207, the mounting mechanism 2 can lock the DIN rail 3 to complete the fixation.

In this process, the coordination between the clamping block 205, the elastic block 206, and the clamping slot 207 can quickly complete the installation and removal of the main structure 1. The position of the movable stopper 204 is changed and fixed. When the block 205 is fixed inside the bottom slot 207, the mounting mechanism 2 can be separated from the DIN rail 3. When the block 205 is fixed inside the top slot 207, the mounting mechanism 2 can lock the DIN rail 3 to complete the fixation. The spring 208 allows the staff to move the elastic block 206 to make the block 205 fall out of the slot 207.
