Description

Technical Field

[0001] This utility model relates to the field of high-voltage motor technology, specifically to a high-voltage motor insulation sensor mounting bracket. Background Technology

[0002] In the field of high-voltage motors, the installation of insulation sensors is a crucial step in ensuring the reliability and performance stability of the motor system. High-voltage motors are widely used in industrial production and typically operate in complex industrial environments characterized by high temperature, high humidity, and high vibration. Their operating conditions directly affect the safety, efficiency, and lifespan of the equipment. Therefore, the installation location and method of the insulation sensors are of paramount importance to ensuring the safe operation of high-voltage motors. Proper installation allows for real-time monitoring of the motor's operating status and precise monitoring of insulation performance, effectively preventing insulation aging, electrical short circuits, and other electrical faults.

[0003] Patent CN222028310U discloses a mounting bracket for an insulation sensor of a high-voltage motor. The bracket includes a high-voltage motor body, a mounting frame, and an insulation sensor body; a clamping mechanism including a platform and a fixing claw; and a connecting mechanism including a connecting post and a connecting hole. This design effectively prevents the insulation sensor from vibrating during high-voltage motor operation, improving the accuracy of data measurement. The dual design of physical and electrical interlocks ensures the insulation sensor is firmly fixed during high-voltage motor operation, avoiding accidental movement and the risk of electric shock. Clamping and unclamping are achieved using a motor and remote control, making operation more convenient, reducing the difficulty for operators, minimizing the impact of external factors on sensor measurement accuracy, improving data reliability, enhancing installation stability, simplifying the operation process, and reducing measurement errors. This provides an innovative solution for the field of high-voltage motors.

[0004] In practical use, the aforementioned existing technology first attaches the insulating sensor body to the platform surface, then starts the motor, which drives the turntable to rotate via the transmission shaft. This causes the driven teeth and bars, which are engaged with the transmission gears, to slide, thus limiting and fixing the insulating sensor body. When it is necessary to release the insulating sensor, simply drive the motor in the opposite direction to unlock it. However, this bracket still has the following shortcomings in practical applications: First, this design relies on the motor for power, requiring power during both the installation and removal of the insulating sensor body. This not only increases the limitations of the usage conditions but also brings inconvenience in certain working conditions, such as when the high-voltage motor is shut down for maintenance. Second, the transmission structure of this bracket is relatively complex. In the unavoidable vibration environment during the operation of the high-voltage motor, many transmission components are prone to wear or misalignment, leading to a decrease in the stability of the bracket or even failure, affecting its service life. In view of this, we propose a high-voltage motor insulating sensor mounting bracket. Utility Model Content

[0005] The purpose of this utility model is to provide a mounting bracket for a high-voltage motor insulation sensor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

Next, the user pulls the pull rod 42 upward so that the bottom end of the insertion rod 41 moves upward from the rectangular slot 21. Then, the user inserts the rear end of the rectangular connecting block 5 into the rectangular slot 21 in the fixing base 2. At this time, the user releases the pull rod 42, and the locking piece 4 will automatically slide into place to fix the rectangular connecting block 5 in the rectangular slot 21, thereby realizing the quick installation of the insulation sensor body 3.

[0045] Throughout the process, the design of spring 43 ensures that the insertion rod 41 automatically resets when not in operation, providing reliable safety. At the same time, the vibration absorption function of rectangular rubber block 6 and rubber plate 62 further protects the insulation sensor from the vibration of the high-voltage motor, ensuring its measurement accuracy.
