Description

Technical Field

[0001] The utility model relates to the field of power system application equipment, in particular to a connection device for a high-voltage isolating switch / grounding switch. Background Art

[0002] The isolating switch is the most widely used common switchgear in the power system, used to protect the safety of equipment. The grounding switch is a common mechanical grounding device to ensure the personal safety of maintenance personnel during power outages.

[0003] There's a vertical distance of approximately two meters between the main body of an outdoor high-voltage disconnector / earthing switch and its operating mechanism. Clamps and vertical connecting rods are required to connect the operating mechanism to the disconnector / earthing switch body. Due to large construction tolerances in outdoor locations, the disconnector / earthing switch body and the operating mechanism's operating axis often become misaligned after installation. This complicates the installation and commissioning of the vertical connecting rod, increasing installation costs and reducing work efficiency.

[0004] Therefore, based on the above problems, the present invention provides a connecting device for an isolating switch / earthing switch. Utility Model Content

[0005] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides a connecting device for an isolating switch / earthing switch.

[0008] The coupling and the connecting head, the connecting head and the clamping block, and the joint and the vertical connecting rod are all connected by hole pin I and hole pin II, which can obtain rotational freedom in three directions. The coupling can translate left and right along the axis of hole pin I to obtain axial translation freedom to correct the coaxiality error between the disconnector / earthing switch body and the output shaft of the operating mechanism.

[0009] Furthermore, the connector is a stepped shaft, a rectangular groove is provided on the larger end of the shaft to cooperate with the block, and a hole is provided on the other end of the shaft to cooperate with the hole pin I.

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Unless otherwise defined, technical or scientific terms used in this utility model shall have the common meanings understood by persons skilled in the art in the field to which this utility model belongs. The terms "I," "II," and similar terms used in this utility model do not denote any order, quantity, or importance, but are simply used to distinguish different components. Terms such as "connect," "couple," and similar terms are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0025] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0026] The utility model discloses a connecting device for an isolating switch / earthing switch, which has a simple structure design, convenient installation and reliable connection.

[0027] See also Figure 1-8 A connection device for an isolating switch / earthing switch, comprising a coupling 1, a clamping block 2, a connector 3, a block 4, a pin with a hole Ⅰ 5, a flat washer Ⅰ 6, a split pin Ⅰ 7, a vertical connecting rod 8, a nut 9, a bolt 10, a pin with a hole Ⅱ 11, a flat washer Ⅱ 12, a split pin Ⅱ 13, and a connector 14; the larger end of the coupling 1 is connected to the operating mechanism, and the other end is placed in the groove of the connector 3, and then the two blocks 4 are respectively placed in the grooves of the connector 3 for limiting, and then the pin with a hole Ⅰ 5 is sequentially passed through the flat washer Ⅰ 6, the block 4, the coupling 1, the block 4, and the flat washer Ⅰ 6, and then the split pin Ⅰ 7 is respectively inserted into the two holes of the pin with a hole Ⅰ 5, and the opening is opened (see Figure 1 ), at this time, the connector 3 can be axially aligned with the pin Ⅰ5 (see Figure 7 The two clamps 2 are clamped together with the grooves to clamp the vertical connecting rod 8. Then, insert the eight bolts 10 into the clamps 2 and tighten them with nuts 9. Place the small shaft end of the connector 3 into the groove formed by the two clamps 2. Insert the hole pin Ⅰ5 into the flat washer Ⅰ6, clamp 2, connector 3, clamp 2, and flat washer Ⅰ6 in sequence. Then, insert the split pin Ⅰ7 into the two holes of the hole pin Ⅰ5 respectively. Pry open the holes. At this time, the clamp 2 assembly can be rotated with the axis of the hole pin Ⅰ5 (see Figure 8 The joint 14 is inserted into the vertical connecting rod 8, and the hole pin Ⅱ 11 is inserted into the flat washer Ⅱ 12, the joint 14, the vertical connecting rod 8, the joint 14, and the flat washer Ⅱ 12 in sequence. Then, the split pin Ⅱ 13 is inserted into the two holes of the hole pin Ⅱ 11 respectively, and the split pin Ⅱ 13 is opened. At this time, the joint 14 can rotate with the axis of the hole pin Ⅱ 11 (see Figure 8 Make radial rotation around point C in the middle to obtain the rotational freedom in that direction.

[0028] After the isolating switch / earthing switch body and the operating mechanism are installed, the nut 9 can be loosened to debug the vertical connecting rod connection, or the connector 3 can be moved left and right (see Figure 4 ) for debugging. After debugging is completed, tighten the nuts to complete the installation.

[0029] With the above structure, when there is a coaxiality error between the disconnector / earthing switch body and the operating shaft of the operating mechanism, the coaxiality can be corrected by simply loosening the nuts and adjusting the positions of the various components of the device without disassembling the installed disconnector body and operating mechanism. The vertical connecting rod can be quickly inserted and the nuts can be tightened at the installation site to achieve connection.
