Description

Technical Field

[0001] This utility model relates to the field of auxiliary installation technology for auxiliary switches, and in particular to an auxiliary switch adapter. Background Technology

[0002] In the maintenance and repair of pole-mounted grounding switches in conventional substations of 220kV and below, maintenance personnel need to perform systematic maintenance on the stationary contacts, moving contacts, base, and transmission components of the equipment body, and at the same time carry out special maintenance on the core component of the operating mechanism—the auxiliary switch. As the core execution unit of the grounding switch control circuit, the auxiliary switch undertakes key functions such as transmitting opening and closing commands, signal feedback, and equipment interlocking protection. Its reliability directly affects the overall operating status of the grounding switch.

[0003] Currently, auxiliary switch replacement during maintenance mainly involves three stages: initial model verification and spare parts preparation, old part disassembly, and new part installation. The first two stages have standardized operating procedures and relatively fixed timeframes. However, the installation of the new auxiliary switch, due to its high complexity, has become a bottleneck restricting maintenance efficiency. Specifically, the installation process requires repeated calibration of the mechanical fit dimensions between the auxiliary switch body and the operating mechanism, as well as precise matching of the flange mounting holes. This process involves dimensional adjustments and meticulous alignment. According to on-site maintenance data, flange hole alignment alone accounts for more than 40% of the overall installation time. This traditional installation method not only prolongs equipment downtime but also significantly increases the workload of maintenance personnel due to repeated adjustments. Utility Model Content

Figure 1 As shown, the first direction is arranged along the up and down direction, so that the two installation cavities form a double-layer structure of the base 1, so that the volume is small, and the space is small.In addition, when selecting the material of the base 1, the mechanical properties, fatigue limit, yield strength, toughness, corrosion resistance, cost and processing technology of the material should be considered comprehensively;At the same time, according to the actual application demand, cost budget and the feasibility of processing technology, comprehensive evaluation is carried out to ensure the overall performance and service life of the adapter, such as: the base 1 adopts die steel material.

[0033] In the embodiment of the utility model, adjusting assembly 2 includes first adjusting rod 201 and second adjusting rod 202, first adjusting rod 201 and second adjusting rod 202 are oppositely arranged, one end of both can extend into the installation cavity, and is configured to move towards or away from each other along the second direction, so as to change the distance between the other end of both, so that the first adjusting rod 201 and the second adjusting rod 202 are inserted into different first mounting holes or second mounting holes, and play the role of transfer connection. In this way, the two adjusting rods at one installation cavity can be inserted into two first mounting holes;Similarly, the two adjusting rods at the other installation cavity can be inserted into two second mounting holes, and form an integral whole through the base 1, so as to realize the indirect hole alignment of the first and second mounting holes, improve the installation efficiency and reduce the length of power outage operation.

[0034] On the other hand, there are many types of auxiliary switches on the market, such as: the first auxiliary switch with a flange diameter of 32mm, a hole diameter of 5mm and 10 holes;The second auxiliary switch with a flange size of 32mm*70mm, a hole diameter of 5mm and 8 circumferential holes;Therefore, in order to adapt the adapter to the installation requirements of many different types of auxiliary switches, the first adjusting rod 201 and the second adjusting rod 202 are arranged to be movable, and the two adjusting rods are adaptively adjusted according to the distance of the mounting hole, so as to avoid the difficulty of hole alignment caused by the inconsistency of new and old auxiliary switch models, and improve the universality of the adapter.

[0035] The embodiment sets a switching piece between the auxiliary switch and the operating mechanism, so that the switching piece can be used as an intermediate connecting member and is not affected by each hole position, thereby improving the installation time of the auxiliary switch, shortening the power-off time, improving the versatility of the switching piece, and adapting the switching piece to auxiliary switches of different models.

[0036] As shown in Figure 2 , Figure 3 , in an embodiment, the two adjusting assemblies 2 are independently arranged from each other. Specifically, in order to enable the two adjusting assemblies 2 to be independently operated and not to affect each other, the embodiment sets the two adjusting assemblies 2 to be independent of each other, so that the respective adjusting rod groups can be independently moved to facilitate adjustment according to actual hole positions.

[0037] As shown in Figure 1 , Figure 2 , in an embodiment, the mounting cavity is provided with a sliding groove 3 in the second direction, and the first adjusting rod 201 and the second adjusting rod 202 are slidably arranged in the sliding groove 3. Specifically, in order to enable the first adjusting rod 201 and the second adjusting rod 202 to move towards or away from each other, the embodiment sets a sliding groove 3 in the mounting cavity, so that one end of each adjusting rod extending into the mounting cavity is slidably arranged in the sliding groove 3, and the sliding groove 3 is arranged in the second direction to guide each adjusting rod and constrain the path of each adjusting rod, so that each adjusting rod can be repeatedly used. Of course, in order to reduce the overall volume of the base 1, the sliding groove 3 can entirely cover the corresponding mounting cavity, that is, the mounting cavity is the sliding groove 3. In addition, in order to enable each adjusting rod to extend out of the mounting cavity to be externally connected, a strip-shaped notch is formed on the upper and lower surfaces of the base 1, which can enable each adjusting rod to pass through the strip-shaped notch and reciprocally move without obstruction.

[0038] Preferably, as shown in Figure 1 , the cross section of the sliding groove 3 is elliptical. This can make the switching of the first adjusting rod 201 and the second adjusting rod 202 more stable and reliable, and is suitable for occasions requiring long-term stable movement. In addition, the elliptical double-layer structure has relatively low requirements for materials and can be made of ordinary metal materials, which has low processing difficulty.

[0039] As shown in Figure 2 , Figure 3As shown in the drawings, in an embodiment, the first adjusting rod 201 and the second adjusting rod 202 are respectively provided with a first sliding block 4 and a second sliding block 5, and the first sliding block 4 and the second sliding block 5 are slidingly arranged in the sliding groove 3. Specifically, in order to enable the first adjusting rod 201 and the second adjusting rod 202 to slide in the sliding groove 3, the first sliding block 4 and the second sliding block 5 are fixed at the bottom of the first adjusting rod 201 and the bottom of the second adjusting rod 202 respectively, and the first sliding block 4 and the second sliding block 5 are slidingly arranged in the sliding groove 3 to link the movement of the corresponding adjusting rod.

[0040] Further, as shown in the drawings, Figures 1-3 in an embodiment, the first sliding block 4 and the second sliding block 5 are penetrated by a screw rod 6, the screw rod 6 has a first threaded structure 601 and a second threaded structure 602 arranged in opposite directions, and the first threaded structure 601 and the second threaded structure 602 are matched with the first sliding block 4 and the second sliding block 5 respectively. Specifically, in order to drive the first sliding block 4 and the second sliding block 5 to move towards or away from each other synchronously, the screw rod 6 is arranged to penetrate the first sliding block 4 and the second sliding block 5, and the screw rod 6 is divided into two segments by a midpoint (or a near midpoint), the two segments are respectively provided with the first threaded structure 601 and the second threaded structure 602 arranged in opposite directions, and the first sliding block 4 and the second sliding block 5 are respectively provided with a first threaded hole and a second threaded hole matched with the first threaded structure 601 and the second threaded structure 602; in this way, the first sliding block 4 and the second sliding block 5 can be linked to move towards or away from each other by the first adjusting rod 201 and the second adjusting rod 202 by reversing the screw rod 6 with an external force.

[0041] Further, as shown in the drawings, Figure 2 , Figure 3 in an embodiment, the mounting cavity is provided with a fixing seat 8, the fixing seat 8 is located between the first sliding block 4 and the second sliding block 5, and a through hole is formed in the fixing seat 8 for the screw rod 6 to penetrate. Specifically, in order to install the screw rod 6 in each mounting cavity, the fixing seat 8 is arranged in the mounting cavity, as shown in the drawings, Figure 1 the fixing seat 8 is fixed to the base 1 by a positioning pin, and the fixing seat 8 is provided with a through hole for the screw rod 6 to penetrate, so that the screw rod 6 can rotate relative to the fixing seat 8 under the action of an external force.

[0042] As shown in the drawings, Figure 1 , Figure 2 in an embodiment, at least one end of the screw rod 6 protrudes outside the mounting cavity; so as to form a force point, which is convenient for rotating the screw rod 6. As shown in the drawings, Figure 3 a rotating handle 7 is arranged at the end of the screw rod 6, the rotating handle 7 is butterfly-shaped, which is more convenient for rotating the screw rod 6.

[0043] As shown in the drawings, Figures 1-3As shown in the figure, in an embodiment, the first adjusting rod 201 and the second adjusting rod 202 are provided with a third threaded structure 203, and a positioning nut 204 is arranged in the third threaded structure 203. Specifically, in order to install the adapter in the corresponding installation hole, the third threaded structure 203 is arranged on the adjusting rod, and the positioning nut 204 is threadedly connected to the adjusting rod by the third threaded structure 203, so that the adapter is screwed by the positioning nut 204 after the adjusting rod passes through the corresponding installation hole, and the adapter and the external connecting piece form an integral whole, so as to open and close the switch.

[0044] As shown in the figure, Figure 4 In an embodiment, one of the two adjusting assemblies 2 is provided with an auxiliary block 9, which is detachably arranged on the first adjusting rod 201 and the second adjusting rod 202. Specifically, part of the auxiliary switch is of a different structure, so the adjusting rod cannot pass through the hole, and therefore an auxiliary block 9 needs to be added to the adapter. The auxiliary block 9 is detachably arranged on the first adjusting rod 201 and the second adjusting rod 202. When a standard auxiliary switch is installed, the auxiliary block 9 is removed and installed according to the above requirements. When a different auxiliary switch needs to be installed, the auxiliary block 9 is arranged on the first adjusting rod 201 and the second adjusting rod 202, and the auxiliary block 9 is abutted with the external connecting piece, so that the adapter and the external connecting piece form an integral whole, and the installation of the different auxiliary switch is realized.

[0045] In addition, as shown in the figure, Figure 5 The bottom of the auxiliary block 9 is formed with a stepped hole 10 for accommodating the positioning nut 204. On the one hand, the stepped hole 10 realizes the detachable connection of the auxiliary block 9 and the adjusting rod, and on the other hand, the position and height of the positioning nut 204 can be adjusted to control the height of the auxiliary block 9, so that the auxiliary block 9 can be abutted at the corresponding position, and the gap is avoided to cause the connection to fail. As shown in the figure, Figure 5 The hole can be a circular hole, or as shown in the figure, Figure 6 It can be a strip-shaped hole.

[0046] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
