Description

Technical Field

[0001] This utility model belongs to the technical field of power cabinet accessories, and in particular relates to a voltage terminal cover with isolation and dustproof function. Background Technology

[0002] In power systems, secondary control panels serve as crucial installation carriers for secondary equipment and are widely used in various power facilities. Internally, terminal blocks are used to fix and connect contacts. Protection control panels typically contain special types of terminals such as AC voltage terminals and AC current terminals. However, in current field applications, AC voltage and current terminals are often tightly packed with other DC terminal sections without effective isolation measures, leading to the following technical defects: I. Disorganized terminal arrangement and lack of isolation The control panel contains a large number of terminals, and the AC and DC terminal sections are not physically isolated, resulting in a mixed distribution of different types of terminal lines. This layout not only increases the complexity of construction and maintenance but may also lead to wiring errors due to visual confusion, affecting the normal operation of the power system.

[0003] II. Risks and safety hazards of accidental contact Because AC terminal sections lack isolation protection, workers are highly susceptible to accidental contact with AC terminals by hand or tools while performing maintenance and debugging operations inside the control panel, potentially causing equipment malfunctions or safety accidents. Especially in high-voltage environments, accidental contact with AC terminals can lead to serious problems such as short circuits and leakage, threatening the safety of workers and the stability of the power system.

[0004] III. Potential Risks of AC / DC Interference The lack of isolation between AC and DC terminals can lead to cross-current in the AC / DC system due to insulation aging, terminal block damage, or other reasons. Cross-current can cause malfunctions in protection devices and distorted measurement data, severely impacting the protection logic and operational reliability of the power system. Summary of the Invention

[0005] To address the problems in the prior art, this utility model provides a voltage terminal cover with isolation and dustproof function, including a main board with several rows of holes. Each row of holes includes, in sequence, a snap-fit ​​hole, a terminal hole, a slitting hole, a terminal hole, and a snap-fit ​​hole. A first baffle and a second baffle are respectively provided at the upper and lower ends of the main board, and a dustproof cover is provided between the first baffle and the second baffle.

[0006] In a preferred embodiment, both the first baffle and the second baffle are provided with sliding grooves, allowing the dust cover to slide freely along the length of the sliding grooves.

[0007] In a preferred embodiment, the dust cover consists of a frame and a flexible part, with the frame evenly distributed within the flexible part; both ends of the frame are inserted into sliding grooves, allowing it to slide freely along the grooves.

[0008] In a preferred embodiment, an isolation cover is provided above the openings of the snap-fit ​​hole, terminal hole, and slitting hole.

[0009] In a preferred embodiment, the shape of the isolation cover is adapted to the shape of the openings of the snap-fit ​​hole, terminal hole, and slitting hole.

[0010] In a preferred embodiment, the insert rod at the bottom of the isolation cover is inserted into the corresponding socket on the motherboard and is fixed to the motherboard.

[0011] In a preferred embodiment, an isolation enclosure is fixedly installed below the openings of the buckle hole, terminal hole, and slitting hole.

[0012] In a preferred embodiment, the shape of the isolation enclosure is adapted to the shape of the openings of the buckle holes, terminal holes, and slitting holes.

[0013] The beneficial effects of this utility model are: (1) An isolation cover is installed above the openings of the buckle hole, terminal hole and slitting hole, and an isolation plate is fixed below to form a three-dimensional isolation structure of "top cover and bottom block". The shape of the isolation cover and the isolation plate is precisely matched with the opening, which can effectively prevent tools or hands from accidentally touching the terminal contacts, and at the same time isolate the AC terminal and DC terminal segments to avoid AC and DC crosstalk caused by insulation failure, and cut off the crosstalk path from the physical level; (2) The isolation cover is connected to the motherboard by a plug rod, and can be disassembled or installed separately for different types of terminal holes, flexibly adapting to the complex terminal layout in the panel cabinet; (3) The dust cover between the first baffle and the second baffle is composed of a frame and a flexible part, which can slide freely along the slide groove. When the terminal cover is installed in the cabinet, the dust cover can cover the main board area, and the flexible part prevents dust, moisture and other impurities from entering the terminal block.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Example like Figure 1-2 The voltage terminal cover plate with isolation and dustproof function shown includes a main board 1. The main board 1 has several rows of holes. Each row of holes includes a snap-fit ​​hole 101, a terminal hole 102, a slitting hole 103, a terminal hole 102 and a snap-fit ​​hole 101 in sequence. The upper and lower ends of the main board 1 are respectively provided with a first baffle 2 and a second baffle 3. A dustproof cover 5 is provided between the first baffle 2 and the second baffle 3.

[0021] Furthermore, both the first baffle 2 and the second baffle 3 are provided with sliding grooves 4, and the dust cover 5 can slide freely along the length of the sliding grooves 4.

[0022] like Figure 3 The dust cover 5 shown consists of a frame 501 and a flexible part 502. The frame 501 is evenly distributed within the flexible part 502. The flexible part 502 is made of an insulating and deformable material, such as polypropylene, polyethylene, or other insulating plastic materials. The two ends of the frame 501 are inserted into the sliding grooves 4 and can slide freely along the sliding grooves. The frame 501 serves to support the dust cover 5 and the sliding of the frame 501 within the sliding grooves 4 drives the dust cover 5 to slide as a whole.

[0023] Furthermore, an isolation cover 6 is provided above the openings of the buckle hole 101, terminal hole 102 and slitting hole 103. The isolation cover 6 isolates the buckle, terminal and slitting to prevent cross-current.

[0024] Furthermore, the shape of the isolation cover 6 is adapted to the shape of the openings of the snap hole 101, the terminal hole 102, and the slitting hole 103.

[0025] Furthermore, the insertion rod 7 at the bottom of the isolation cover 6 is inserted into the corresponding socket of the motherboard 1 and is snapped and fixed to the motherboard 1. The snap-fit ​​method between the isolation cover 6 and the motherboard 1 allows for convenient disassembly or installation for different types of holes.

[0026] Furthermore, an isolation enclosure 8 is fixedly installed below the openings of the buckle hole 101, terminal hole 102 and slitting hole 103. The lower part of the enclosure isolates the buckle, terminal and slitting, and each buckle, terminal and slitting forms an independent small space that does not interfere with each other, further preventing cross-current.

[0027] Furthermore, the shape of the isolation panel 8 is adapted to the shape of the openings of the buckle hole 101, the terminal hole 102, and the slitting hole 103.

[0028] The above-mentioned cover plate is used as follows: Align the lower isolation panel 8 with the buckles, terminals, and slitting parts, and insert it into the cabinet so that the isolation panel 8 covers each buckle, terminal, and slitting part. The isolation cover 6 also further isolates each buckle, terminal, and slitting part from above. When the terminals are not in use, pull up the dust cover 5 to prevent dust and other substances from entering the cover plate. When the terminals need to be used, pull up the dust cover 5, remove the corresponding isolation cover 6, and operate on the corresponding terminals. After the operation is completed, insert the plug 7 of the isolation cover 6 into the corresponding socket.
