Description

Technical Field

[0001] This utility model relates to the field of discharge coil technology, specifically a high-voltage parallel capacitor discharge coil. Background Technology

[0002] The high-voltage parallel capacitor discharge coil is a safety protection device used in conjunction with high-voltage parallel capacitor banks. It is mainly used to quickly discharge the residual charge stored in the capacitor bank after the power is cut off, so as to ensure the safety of equipment and personnel. It is an indispensable safety component in high-voltage power systems, and has three functions: charge discharge, equipment protection and system monitoring.

[0003] When installing existing high-voltage parallel capacitor discharge coils, mounting holes are usually set on the bottom feet. Bolts are then passed through the mounting holes and screwed into the mounting holes for fixation. The mounting holes are usually round, but it is difficult to align round holes with the mounting holes. Therefore, sometimes the mounting holes are set as oblong holes to facilitate alignment with the mounting holes. However, the bolts are prone to displacement between the oblong holes and the bolts, resulting in the high-voltage parallel capacitor discharge coils not being installed securely. Utility Model Content

[0004] The purpose of this invention is to provide a high-voltage parallel capacitor discharge coil to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage parallel capacitor discharge coil, comprising a discharge coil housing, a terminal block disposed on the top of the discharge coil housing, and two feet fixedly mounted on the bottom of the discharge coil housing. Each end of the two feet is provided with a fixing groove, which is composed of multiple circular holes connected to each other. Fastening bolts are inserted into the circular holes. Multiple insertion holes are provided on the top of the two feet. Anti-rotation blocks are detachably mounted on each foot. A hexagonal hole is provided in the center of each anti-rotation block. A protrusion extends outward from the outer side of the anti-rotation block. A plug rod is integrally formed at the bottom of the protrusion to engage with the insertion hole. Elastic plates are symmetrically provided on the plug rod.

[0006] In a preferred embodiment of this utility model, the center of the insertion hole and the center of the adjacent circular hole are on the same straight line.

[0007] In a preferred embodiment of this utility model, the diameter of the insertion rod is equal to the diameter of the insertion hole, and the bottom of the insertion rod is chamfered.

[0008] As a preferred embodiment of this utility model, a grounding bolt is provided on the outer side of the base.

[0009] In a preferred embodiment of this utility model, the diameter of the screw of the fastening bolt is equal to the diameter of the circular hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the fixed groove of this utility model is composed of multiple round holes, which allows the position of the fastening bolt to be adjusted so as to align with the mounting hole. After the fastening bolt passes through the round hole, there is no displacement between the fastening bolt and the fixed groove. At the same time, the anti-rotation block can prevent the fastening bolt from loosening, thereby ensuring that the discharge coil shell is firmly installed. Attached Figure Description

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 4This utility model provides a technical solution: a high-voltage parallel capacitor discharge coil, including a discharge coil housing 1, a terminal block 2 disposed on the top of the discharge coil housing 1, and two feet 3 fixedly installed on the bottom of the discharge coil housing 1. Each end of the two feet 3 has a fixing groove 6. When installing the discharge coil housing 1, fastening bolts 12 are passed through the fixing grooves 6 and screwed into the mounting holes to fix the feet 3, thereby achieving the installation and fixation of the discharge coil housing 1. The fixing grooves 6 are composed of multiple round holes 61, allowing the position of the fastening bolts 12 to be adjusted for alignment with the mounting holes. Furthermore, after the fastening bolts 12 pass through the round holes 61, there is no displacement between the fastening bolts 12 and the fixing grooves 6, thus ensuring that the discharge coil housing 1 is firmly installed. Adjacent round holes 61 are connected, and fastening bolts 12 pass through the round holes 61. Multiple insertion holes 5 are provided on the top of the two base feet 3. An anti-rotation block 7 is detachably installed on the base feet 3. A hexagonal hole 8 is provided in the middle of the anti-rotation block 7. The hexagonal hole 8 is adapted to the head of the fastening bolt 12. The anti-rotation block 7 can limit the fastening bolt 12 through the hexagonal hole 8 to prevent the fastening bolt 12 from loosening due to vibration, which would cause the discharge coil shell 1 to be not securely installed. The outer side of the anti-rotation block 7 extends outward to form a protrusion 9. The bottom of the protrusion 9 is integrally formed with a plug rod 10 that is inserted into the insertion hole 5. The plug rod 10 is symmetrically provided with elastic plates 11. When the plug rod 10 is inserted into the insertion hole 5, the elastic plates 11 will contract and stick to the plug rod 10. When the bottom of the protrusion 9 contacts the top of the base foot 3, the elastic plates 11 just completely pass through the insertion hole 5. The elastic plates 11 spring open and reset, so that the plug rod 10 cannot be separated from the insertion hole 5, thereby fixing the anti-rotation block 7.

[0018] Among them, the center of the socket 5 is on the same straight line as the center of the adjacent round hole 61.

[0019] The diameter of the insertion rod 10 is equal to the diameter of the insertion hole 5, so that the insertion rod 10 will not wobble after being inserted into the insertion hole 5. The bottom of the insertion rod 10 is chamfered, which makes it easier to align the insertion rod 10 with the insertion hole 5 and insert it.

[0020] Among them, the outer side of the base 3 is provided with a grounding bolt 4, which is used to connect to the wiring system so that abnormal current can be quickly conducted to the ground and improve safety.

[0021] The diameter of the screw of the fastening bolt 12 is equal to the diameter of the circular hole 61, so that when the fastening bolt 12 passes through the circular hole 61, it cannot be displaced from the circular hole 61.

[0022] Specifically, when installing the discharge coil housing 1, align the fixing groove 6 with the mounting hole, then pass the fastening bolt 12 through the fixing groove 6 and screw it into the mounting hole. After tightening the fastening bolt 12, take out the anti-rotation block 7, align the hexagonal hole 8 with the fastening bolt 12, so that the anti-rotation block 7 is fitted onto the head of the fastening bolt 12, and insert the insertion rod 10 into the insertion hole 5. When inserted, the elastic piece 11 will be squeezed and contracted by the bottom foot 3 to fit tightly against the insertion rod 10. When the elastic piece 11 passes through the insertion hole 5, the elastic piece 11 springs open and resets, so that the insertion rod 10 cannot be separated from the insertion hole 5. Under the action of the insertion rod 10, the anti-rotation block 7 cannot rotate, and the anti-rotation block 7 restricts the fastening bolt 12 from rotating, preventing the fastening bolt 12 from loosening, thereby ensuring that the discharge coil housing 1 is installed firmly.
