Description

Technical Field

[0001] This utility model belongs to the field of vacuum contactor technology, and specifically relates to a quick-release vacuum contactor. Background Technology

[0002] In power systems, vacuum contactors are widely used for controlling the switching of circuits. A vacuum contactor mainly consists of a vacuum interrupter and an operating mechanism. The vacuum interrupter has two functions: reliably extinguishing arcs when normal operating current is passed through and when frequently interrupting operating current. However, it cannot interrupt overload current or short-circuit current. The operating mechanism consists of a holding coil with an iron core and an armature. When the coil is energized, it attracts the armature, and the contactor closes; when the coil is de-energized, the contactor opens. Holding coils are generally available in both DC and AC versions.

[0003] Existing vacuum contactors present numerous inconveniences in terms of installation and disassembly. Traditional vacuum contactors are typically secured to their mounting positions with a large number of bolts. During equipment maintenance, repair, or replacement, significant time and effort are required to remove and install these bolts, especially in space-constrained environments, where the operational difficulty is even greater, severely impacting work efficiency. Furthermore, the fixed position of existing vacuum contactors after installation makes it difficult to adjust their horizontal position according to actual needs. This fails to meet the requirements in applications demanding high precision in installation or requiring subsequent fine-tuning. Therefore, we need to upgrade and modify the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a quick-release vacuum contactor to solve the problems mentioned in the background art.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 As shown in Figure 5, this embodiment provides a quick-release vacuum contactor, including a device body 1. The device body 1 is provided with an arc-extinguishing hood 2, a vacuum arc-extinguishing chamber 3, and a support frame 7. A base 11 is provided below the support frame 7, and a slot 13 is provided in the support frame 7. A locking block 12 is provided on the base 11, and a plug-in groove 14 is provided in the locking block 12. A plug-in rod 15 is inserted into the plug-in groove 14. A screw hole 16 is provided in the plug-in rod 15, and a bolt 17 is provided in the screw hole 16. A nut 20 is screwed below the bolt 17. A mounting frame 23 is provided below the base 11, and a mounting groove 25 is provided in the mounting frame 23. A lead screw 26 is provided in the mounting groove 25. A collar 21 is screwed onto the lead screw 26 and the collar 21 is connected to the base 11. One end of the lead screw 26 is connected to a motor 28.

[0025] Preferably, an insulating baffle 4 is provided inside the arc-extinguishing chamber 2. Multiple sets of insulating baffles 4 are provided, and a vacuum interrupting chamber 3 is provided on the side of the insulating baffle 4. By setting the insulating baffle 4, the space inside the arc-extinguishing chamber 2 can be divided, ensuring the safety and stability of the vacuum interrupting chamber 3 during use. The vacuum interrupting chamber 3 is equipped with contacts 5, terminals 6, and buffer springs 8, which increases the connectivity and intimacy between devices, making it convenient for users to control and use the devices, and providing convenience for users. An electromagnetic box 10 and a coil 9 are installed on the inner wall of the support frame 7. The coil 9 is located below the vacuum interrupting chamber 3. By setting the electromagnetic box 10 and the coil 9, it is convenient for users to control the device, provide power to the device, and ensure the safety and stability of the device during operation.

[0026] Preferably, a guide ring 22 is connected below the support frame 7, and a guide frame 24 is provided below the guide ring 22. A guide rod 27 is fixedly installed inside the guide frame 24, and the guide ring 22 is slidably sleeved on the guide rod 27. By setting the guide ring 22, guide rod 27 and guide frame 24, the direction of movement of the support frame 7 can be guided, ensuring the safety of the support frame 7 during movement and preventing the support frame 7 from shifting position during movement. Multiple sets of bolts 17 are provided, and upper washers 18 and lower washers 19 are movably sleeved on each set of bolts 17. The upper washers 18 are movably and tightly attached to the upper end face of the base 11, and the lower washers 19 are movably and tightly attached to the lower end face of the base 11. By setting the upper washers 18 and lower washers 19, wear on the surface of the base 11 is prevented during the pre-tightening process of the nut 20, thus extending the service life and working time of the device.

[0027] The working principle and operation process of this utility model are as follows: When the coil 9 is energized, it generates electromagnetic force. This force drives the contact 5 through the electromagnetic box 10, causing the contact 5 to close or open, thereby controlling the circuit's continuity. During the operation of the contact 5, the arc-extinguishing cover 2 and the vacuum arc-extinguishing chamber 3 work together to extinguish the arc generated when the contact 5 closes or opens, ensuring circuit safety. When quick installation is required, the locking block 12 on the base 11 is aligned with the locking slot 13 on the support frame 7 for initial positioning. Simultaneously, the insertion rod 15 is inserted into the insertion slot 14 for further positioning. Then, the bolt 17 is passed through the screw hole 16 of the locking slot 13 and pre-tightened with the nut 20 to securely fix the base 11 to the support frame 7. Disassembly is performed in reverse: first, unscrew the nut 20 on the bolt 17, pull out the bolt 17, and then pull the locking block 12 out of the locking slot 13 to separate the base 11 from the support frame 7. When the horizontal position of the vacuum contactor needs to be adjusted, the motor 28 is started, and the motor 28 drives the lead screw 26 to rotate. Since the support frame 7 is threadedly connected to the lead screw 26 through the collar 21 and slidably connected to the guide rod 27 through the guide ring 22, when the lead screw 26 rotates, the support frame 7 moves horizontally along the direction of the guide frame 24 under the guidance of the guide rod 27, thereby realizing the adjustment of the horizontal position of the vacuum contactor.
