Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformer substation isolating switches, and more particularly to a one-button sequential control isolating switch double confirmation device. Background Art
[0002] One-touch sequential control is a high-level application in smart substations and a key technology for promoting the deep integration of modern information technology and power grid technology and building intelligent operation and maintenance systems. With the emergence of the next-generation power system concept, primary equipment will face the challenge of adapting to the new requirements of the secondary system. As a key technology supporting the construction of this new generation of power systems, the one-touch sequential control function for disconnectors requires the introduction of "double confirmation" measures to ensure operational accuracy and equipment safety. This allows the traditional switching operation mode, which relies on manual operation ticket filling and is tedious, repetitive, and prone to error, to be transformed into a remote one-touch sequential control mode.
[0003] However, current signal double confirmation devices in one-touch sequential switches, when double confirmation of multiple signals is involved, typically employ multiple cams mounted on a single shaft, with each cam contacting a corresponding signal switch. For example, if a device has three signals, A, B, and C, requiring double confirmation, three cams are mounted on the shaft. When the device outputs signal A, the cam corresponding to signal A also contacts the corresponding signal switch, achieving double confirmation. This approach consumes considerable space. As the number of signals requiring confirmation increases, the shaft length and overall device volume significantly increase, hindering the compact layout and maintenance of the device.
[0004] Another method is to use only one cam to contact multiple signal switches around it. This method requires the installation of a processor to solve the problem of repeated touch during rotation. It not only increases the complexity and cost of the system, but also increases the risk of processor errors, affecting the stability and reliability of the system. Utility Model Content

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.
[0023] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0024] A one-button sequential control isolating switch double confirmation device, such as Figure 1 and Figure 2 As shown, it includes a base plate 1, on which a gear set 2 is provided. The gear set 2 includes several gears, which are all located in the same plane and have the same thickness. One of the gears is connected to the output shaft of the device. The rotation of the output shaft of the device drives it to rotate synchronously, and indirectly drives the rotation of the remaining gears. Several signal switches 3 are provided on the base plate 1, and several gears respectively trigger a signal switch 3. The signal switches 3 correspond to the signals in the device for double confirmation.
[0025] An abutment block 4 is fixed on the gear, protruding to the outside of the gear. The abutment block 4 rotates synchronously with the gear. A trigger button 301 is provided on the side of the signal switch 3 facing its corresponding gear. The trigger button 301 is part of the signal switch 3. When the gear rotates until the abutment block 4 faces the signal switch 3, the abutment block 4 presses the trigger button 301 to trigger the signal switch 3.
[0026] like Figure 3As shown, a threaded hole 5 is provided on the top of the gear, and a long slot 6 is provided on the abutment block 4. A bolt passes through the long slot 6 and is threadedly connected to the threaded hole 5. The head of the bolt is tightly pressed against the abutment block 4, thereby fixing the abutment block 4 on the gear. The long slot 6 extends radially along the gear, so that the installation position of the abutment block 4 can be adjusted, thereby adjusting the length of the abutment block 4 protruding from the outside of the gear, so that the abutment block 4 can just fit with the trigger switch.
[0027] At least two threaded holes 5 are provided on the top of the gear. By providing at least two threaded holes 5, the abutment block 4 can be prevented from rotational deviation. In this embodiment, two threaded holes 5 are provided, and two long grooves 6 are also provided on the abutment block 4, and the two long grooves 6 correspond one-to-one to the threaded holes 5.
[0028] In this embodiment, the gear set 2 is configured to have several gears meshing in sequence, and the gears are gear plates. The gear set 2 includes a driving gear 201 and several driven gears 202. The driving gear 201 is connected to the output shaft of the device to achieve rotation and drive the driven gears 202 to rotate. Specifically, two driven gears 202 are provided. The driving gear 201 drives the first driven gear 202 to rotate, and the first gear then drives the second gear to rotate. Three rotating shafts are vertically provided on the base plate 1. The driving gear 201 and the driven gear 202 are respectively mounted on the rotating shafts. The inner sides of the gears are connected to the rotating shafts via splines, thereby driving the gears to rotate. The rotating shaft of the driving gear 201 is fixedly connected to the output shaft of the device. The output shaft of the device directly drives the driving gear 201 to rotate through the rotating shaft. The driving gear 201 is located at the end of the gear set 2, and the rotating shafts of the several gears are connected in a straight line.
[0029] like Figure 1 and Figure 2 As shown, a top cover 8 is also provided on the base plate 1. Several connecting columns protrude from the base plate 1. The connecting columns are higher than the abutment blocks 4. Bolts pass through the top cover 8 and are threadedly connected to the connecting columns, thereby fixing the top cover 8 on the base plate 1. The top cover 8 covers the gear set 2. Several notches are provided on the top cover 8. The notches make way for the signal switch 3. Several thread grooves are provided on the base plate 1. The signal switch 3 is passed through the base plate 1 by bolts. Each signal switch 3 corresponds to two thread grooves.
[0030] Several signal switches 3 correspond to gears one by one. The signal switch 3 corresponding to the driving gear 201 is located on the side of the driving gear 201 away from the adjacent gears. The signal switches 3 corresponding to the remaining gears are arranged on both sides or on the same side of the straight line connecting the rotating shafts of the gears. In this embodiment, the signal switches 3 corresponding to the driven gear 202 are all located on the same side.
[0031] The initial position of the abutment block 4 on the gear can be different according to the time when the signal in the device is triggered. By setting the corresponding module and gear, the time when the abutment block 4 on the gear triggers the signal switch 3 is synchronized with the signal trigger time in the device while the gears are sequentially transmitted, thereby performing double confirmation. In this embodiment, the module of the driving gear 201 and the driven gear 202 are both 0.5, the number of teeth of the driving gear 201 is 65, and the number of teeth of the driven gear 202 is 130, which can meet the double confirmation of this embodiment and the device signal.
[0032] The bottom plate 1 can be provided with a positioning hole 7 to assist in positioning the initial position of the gear. Usually, a positioning post is inserted into the positioning hole 7 to block and position the abutment block 4. The positioning post needs to be removed when in use.
[0033] The working process of this utility model is as follows:
[0034] Signals A, B, and C in the device correspond to the driving gear 201, the first driven gear, and the second driven gear, respectively. The output shaft of the device directly drives the driving gear 201 to rotate. When the device triggers signal A, the abutment block 4 on the driving gear 201 just rotates to the key switch, and signal A is double-confirmed. When the device triggers signal B, the abutment block 4 on the first driven gear just rotates to the key switch, and signal B is double-confirmed. When the device triggers signal C, the abutment block 4 on the second driven gear just rotates to the key switch, and signal C is double-confirmed.
[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
