The circuit breaker operating mechanism is a key component in the gas-filled cabinet, which is used to realize the opening and closing operation of the circuit breaker to ensure that the circuit can be quickly and accurately cut off or closed when needed to protect the safety of the equipment and system. The circuit breaker operating mechanism is installed in the gas-filled cabinet through the fixing structure.

[0003] The existing fixing structure of the circuit breaker operating mechanism in the gas-filled cabinet is usually composed of the following parts: a mounting plate, a support column or bracket, a fixing bolt or nut, etc. The working principle is as follows: the mounting plate is connected to the cabinet body as the foundation, the support column supports the operating mechanism components to ensure the stability of the structure, and the fixing bolt or nut firmly fixes it.

[0004] The existing fixing structure of the circuit breaker operating mechanism has the following disadvantages: the positions of the fixing bolts corresponding to the fixing holes on the circuit breaker operating mechanism in the gas-filled cabinet are fixed, which leads to the fact that the production enterprises cannot install different specifications of circuit breaker operating mechanisms in the gas-filled cabinet due to the mismatch between the fixing bolts and the fixing holes. This cannot adapt to the installation of multiple circuit breaker operating mechanisms, and if the circuit breaker operating mechanism is damaged during use and needs to be replaced, the circuit breaker operating mechanism that matches the fixing holes in the gas-filled cabinet also needs to be replaced, which has large use limitations and poor universality. Therefore, a gas-filled cabinet with a circuit breaker operating mechanism fixing structure is proposed to solve the above problems. UTILITY MODEL CONTENTS

Detailed Implementation

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1-5The present invention discloses an inflatable cabinet with a circuit breaker operating mechanism fixing structure, comprising a cabinet body 1, wherein a circuit breaker operating mechanism 2 is assembled inside the cabinet body 1. The circuit breaker operating mechanism 2 includes a base plate 201 and fixing holes 202. A fixing plate 3 for assembling the circuit breaker operating mechanism 2 is fixedly installed inside the cabinet body 1. The fixing plate 3 has several sliding grooves 4. A fixing component 5 for fixing the circuit breaker operating mechanism 2 is slidably assembled in the sliding grooves 4 and its position can be flexibly adjusted. The fixing component 5 includes a slider 501 slidably disposed in the sliding groove 4, a bolt 502 fixedly disposed on one side of the slider 501, a nut 503, and a washer 504. During operation, the cabinet body 1 serves as the overall outer shell, and the fixing plate 3 inside serves as the circuit breaker operating mechanism. The installation of the circuit breaker operating mechanism 2 provides a flat foundation. The slide 4 is used to accommodate the sliding fixing component 5. The slider 501 can move flexibly within the array of slides 4. According to the different specifications of the fixing holes of the circuit breaker operating mechanism 2, the slider 501 is adjusted to the corresponding slide 4. By adjusting the position of the slider 501, the bolt 502 is aligned with the fixing hole 202 on the base plate 201 of the circuit breaker operating mechanism 2. Then, the circuit breaker operating mechanism 2 is fixed to the fixing plate 3 with the nut 503 and the washer 504, thereby realizing the installation of the operating mechanism in the cabinet 1. This design can flexibly adjust the fixing component 5 according to the specific fixing hole 202 position of the circuit breaker operating mechanism 2, which improves the compatibility with different specifications of operating mechanisms, facilitates installation, and reduces the installation difficulties caused by differences in operating mechanisms.

[0026] Furthermore, both the slide groove 4 and the slider 501 are trapezoidal structures that mate with each other. During operation, the trapezoidal slide groove 4 and slider 501 utilize the hypotenuse of the trapezoid to facilitate the insertion of slider 501 into the slide groove 4. Simultaneously, after installation, the trapezoidal shape provides a significant restraining force on slider 501 in the direction perpendicular to the slide groove 4, effectively preventing slider 501 from detaching from the slide groove 4. This improves the stability of slider 501 within the slide groove 4, ensuring that the fixing component 5 does not detach from the slide groove 4, enhancing the reliability of the entire fixing structure, and ensuring that the circuit breaker operating mechanism 2 is securely fixed. Furthermore, during the tightening of the nut 503, the nut 503 applies an axial tensile force to the bolt 502. This pulling force is transmitted to the slide 4 through the slider 501. Since the slider 501 and the slide 4 are trapezoidal structures, the side of the slider 501 will abut more tightly against the inner wall of the slide 4 under the action of the pulling force. This abutment will generate a component force perpendicular to the inclined surface of the trapezoidal structure. The resultant force of these components in the horizontal direction is zero, but a downward pressure component will be generated in the direction perpendicular to the bottom surface of the slide 4, so that the slider 501 is pressed more firmly into the slide 4. This structure makes the connection between the slider 501 and the slide 4 more stable after the nut 503 is tightened, ensuring the reliability of the circuit breaker operating mechanism 2 and improving the safety of the entire gas-insulated switchgear during operation.

[0027] Furthermore, the slider 501 includes a first side 5011 and a second side 5012. The length of the second side 5012 is less than the opening width of the slide groove 4, and the length of the first side 5011 is greater than the opening width of the slide groove 4. During operation, during installation, the slider 501 is inserted into the slide groove 4 with the second side 5012 perpendicular to the opening of the slide groove 4. Since the second side 5012 is less than the opening width of the slide groove 4, it can be smoothly inserted into it. After insertion, the slider 501 is rotated 90 degrees. The first side 5011 is greater than the opening width of the slide groove 4, which ensures the stability of the slider 501 in the slide groove 4 during fixing. This facilitates the installation process of the slider 501 and further strengthens the fixing effect of the slider 501 in the slide groove 4, preventing the slider 501 from accidentally falling off. This improves the stability and reliability of the entire fixing structure and ensures the stable installation of the circuit breaker operating mechanism 2.

[0028] Furthermore, the fixing component 5 also includes a braking component 6, which includes a mounting groove 601 on one side of the slider 501. A compression spring 602 is fixedly installed in the mounting groove 601, and a top block 603 is fixedly installed at the other end of the compression spring 602, abutting against the inner wall of the slide groove 4. During operation, when the operator adjusts the position of the slider 501 according to the fixing holes 202 at different positions on the circuit breaker operating mechanism 2, when the slider 501 slides in the slide groove 4, the compression spring 602 is in a compressed or extended state, and the top block 603 abuts against the inner wall of the slide groove 4. The friction of the inner wall of the groove 4 achieves the braking function. When the slider 501 moves to the target position, the elastic force of the compression spring 602 makes the top block 603 press more tightly against the inner wall of the groove 4, increasing the friction and stopping the slider 501 at that position. This allows the slider 501 to stabilize quickly after moving to the appropriate position, avoiding positional deviation of the slider 501 due to vibration or other external forces. It ensures the alignment accuracy of the fixing component 5 and the fixing hole 202 of the circuit breaker operating mechanism 2, facilitating subsequent installation operations and improving the stability of the entire fixing structure during use.

[0029] Furthermore, the fixed plate 3 has a series of symmetrical mounting slots 7, and a butterfly spring 8 is fixedly installed in the mounting slot 7. One end of the butterfly spring 8 extends out of the mounting slot 7 and abuts against the base plate 201. During operation, when the circuit breaker operating mechanism 2 is fixed on the fixed plate 3, the butterfly spring 8 is compressed by the pressure of the base plate 201, and the butterfly spring 8 generates an upward elastic force. This elastic force applies a supporting force to the circuit breaker operating mechanism 2, keeping it stable in the vertical direction, improving the firmness of the fixed structure, and buffering the vibration generated during the operation of the operating mechanism to a certain extent. It provides stable support and buffering for the circuit breaker operating mechanism 2 in the vertical direction, reducing the damage to the cabinet 1 and itself caused by vibration during operation, extending the service life of the equipment, and improving the stability of the operating mechanism, reducing the probability of failure caused by vibration.

[0030] Furthermore, a scale 9 is provided on the fixing plate 3 at the edge of the slide groove 4; during operation, when adjusting the position of the slider 501, the operator can accurately determine the moving distance and position of the slider 501 by observing the relative position of the slider 501 and the scale 9, so as to accurately align the bolt 502 with the fixing hole 202 of the circuit breaker operating mechanism 2, providing an intuitive reference for the positioning of the slider 501, improving the installation accuracy and efficiency, reducing the errors that may be caused by manual judgment of the position of the slider 501, and facilitating the installer to quickly and accurately complete the fixing work of the circuit breaker operating mechanism 2.
