Description
Technical Field

[0002] With the development of economy, the demand for electricity is also increasing. As the main equipment in the power transmission and transformation system, transformers have also made great progress. In order to adapt to and meet market demand, many manufacturers have continuously improved product structure, improved product performance, introduced advanced production technology and equipment from abroad, and made unremitting efforts in the exploration of new processes and new materials, so as to continuously improve product quality and reliability, and have made great progress. Commonly used transformers can be divided into single-phase transformers and three-phase transformers according to the number of phases.
[0003] Load switch is one of the most important components in transformer. Load switch is a switching device used to control the flow of current in power system, especially at the output end of transformer. The main function of load switch is to switch when the device is running (under load), allowing or blocking the current, so as to achieve the management and protection of power system.
[0004] The operation of a load switch usually involves two main components: contacts and operating mechanisms. Among them, contacts are the core components of a load switch and are responsible for connecting and disconnecting the current. When the contacts are in contact, the current can flow; when the contacts are disconnected, the current is cut off. The operating mechanism is used to control the connection and disconnection of the contacts. It can be mechanical, electric or pneumatic, and is responsible for quickly opening or closing the contacts under the command of the user or system control signal.
[0005] The operation of the operating mechanism in the prior art is achieved by rotation so as to cooperate with the corresponding electrode. However, the exposed design of the rotary operating mechanism makes it exposed to the outside, and it may be accidentally touched if not careful, thus causing safety accidents.

[0027] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content. Example
[0028] The present invention discloses a transformer that prevents accidental contact, such as Figure 1 and Figure 2 As shown, it includes a mounting base 1 and a terminal 2 fixed on the upper surface of the mounting base 1, a control cavity is provided inside the mounting base 1, a fixed sleeve 3 is provided inside the control cavity, an insulating pull rod 4 is slidably provided inside the fixed sleeve 3, a moving contact 5 is fixedly installed at one end of the insulating pull rod 4, the moving contact 5 is matched with a static contact arranged in the control cavity, and a connecting rod control component 6 is provided at the other end of the insulating pull rod 4, through which the insulating pull rod 4 is slidably set inside the fixed sleeve 3 and controls the connection between the moving contact 5 and the static contact.
[0029] like Figure 1 and Figure 2 As shown, when the connecting rod control assembly 6 is operated, it will drive the insulating pull rod 4 to slide in the fixed sleeve 3; the movement of the insulating pull rod 4 directly controls the connection or disconnection between the moving contact 5 and the static contact; when the insulating pull rod 4 pushes the moving contact 5 to contact the static contact, the circuit is closed; the pull rod is pulled back, the moving contact 5 is separated from the static contact, and the circuit is disconnected; the whole process relies on mechanical transmission, which is simple and reliable.
[0030] like Figure 2 As shown, an insulating reset fiber 7 for resetting is provided between the fixed sleeve 3 and the moving contact 5. The insulating reset fiber 7 is spring-shaped and sleeved on the outside of the insulating pull rod 4. The moving contact 5 contacts the fixed sleeve 3 in the working state to complete the on-off of the circuit; when the moving contact 5 needs to be reset, the spring-shaped insulating reset fiber 7 will provide a force to restore to the initial position due to its elasticity; this force overcomes the existing resistance and pushes the moving contact 5 back to the position separated from the fixed sleeve 3, thereby disconnecting the circuit; the insulation of the insulating reset fiber 7 ensures that no short circuit occurs during the resetting process.
[0031] like Figure 2 As shown, the spring-like structure provides a reliable reset force, ensuring that the moving contact 5 can reliably return to the initial position after the work is completed, avoiding jamming or malfunction; using spring-like reset fibers instead of other complex reset mechanisms simplifies the structure of the device and reduces manufacturing costs and complexity.
[0032] like Figure 2 As shown, the insulating reset fiber 7 is made of polyurethane, which has good elasticity and electrical insulation, but a suitable formula needs to be selected.

[0034] like Figure 2 As shown, an integrated rod 11 is provided in the control cavity of the mounting base 1, and three groups of insulating pull rods 4 are provided. The three groups of insulating pull rods 4 are fixed on the integrated rod 11, and the three groups of insulating pull rods 4 are combined together through the integrated rod 11. The integrated rod 11 is connected to the above-mentioned connecting rod control assembly 6 for unified control and driving of the insulating pull rods 4.
[0035] like Figure 3 As shown, the connecting rod control assembly 6 includes a positioning wheel 601 arranged on a side surface of the mounting base 1, a hand wheel 602 is rotatably provided inside the positioning wheel 601, a socket is provided inside the hand wheel 602, a positioning collar 604 is coaxially connected to the outer side of the positioning wheel 601, a plurality of mounting holes 605 are equiangularly provided inside the positioning collar 604, the socket and the mounting hole 605 match each other, the driving of the connecting control assembly is controlled by rotating the hand wheel 602, when the socket on the hand wheel 602 is aligned with the mounting hole 605, the hand wheel 602 and the positioning collar 604 are locked by the insertion rod 603 provided in the socket.
[0036] like Figure 3 As shown, the number of the sockets on the hand wheel 602 and the mounting holes 605 on the positioning collar 604 is limited, and the mounting holes 605 are distributed at equal angles; only when the hand wheel 602 is rotated to a specific position and the socket is aligned with a certain mounting hole 605, the insertion rod 603 can be inserted, thereby locking the hand wheel 602 and the positioning collar 604; this locking mechanism ensures that the operation can only be performed at a preset, safe angle, effectively preventing accidental operation.
[0037] like Figure 3 and Figure 4As shown, the connecting rod control assembly 6 also includes a special-shaped shaft 606 coaxially connected to the inside of the hand wheel 602 and a fixed block 607 arranged in the control cavity of the mounting base 1, a lower concave portion 608 is formed in the middle of the special-shaped shaft 606, a limit sleeve 609 is rotatably provided on the lower concave portion 608 of the special-shaped shaft 606, an extension rod 6015 is fixedly installed on the radial surface of the limit sleeve 609, one end of the extension rod 6015 is fixedly connected to the limit sleeve 609, the other end of the extension rod 6015 is connected to an extension block 6016, and the interior of the extension block 6016 passes through a limit slide Rod 6010, one end of the limiting slide rod 6010 is rotatably connected to the mounting base 1 through a rotating shaft 6011, a sliding sleeve 6012 is slidably provided on the limiting slide rod 6010, and a special-shaped block 6013 with an L-shaped cross-section is hingedly provided on the fixed block 607. Specifically, the middle part of the special-shaped block 6013 is hingedly arranged between the fixed block 607, one end of the special-shaped block 6013 is hingedly arranged with the sliding sleeve 6012, and the other end of the special-shaped block 6013 is hingedly arranged with a connecting rod 6014, and the connecting rod 6014 is hingedly arranged between the bottom center of the integrated rod 11.
[0038] like Figure 4 and Figure 5 As shown, by rotating the hand wheel 602, the special-shaped shaft 606 is rotated, and the lower recess 608 in the middle of the special-shaped shaft 606 produces a longitudinal displacement, and under the action of the limiting sleeve 609, the limiting slide rod 6010 is driven to rotate around the rotating shaft 6011, thereby causing the special-shaped block 6013 and the connecting rod 6014 to be linked, so that the integrated rod 11 produces a longitudinal displacement.
[0039] like Figure 4 and Figure 5 As shown, the rotation of the handwheel 602 drives the coaxial special-shaped shaft 606 to rotate; the unique concave design in the middle of the special-shaped shaft 606 converts the rotational motion into the longitudinal displacement of the concave portion 608; this longitudinal displacement is transmitted to the limiting slide 6010 through the limiting sleeve 609; the limiting sleeve 609 limits the displacement range of the special-shaped shaft 606; the displacement of the limiting slide 6010 causes it to rotate around the rotating shaft 6011; the rotational motion of the limiting slide 6010 is transmitted to the L-shaped special-shaped block 6013 through the sliding sleeve 6012; the movement of the L-shaped special-shaped block 6013 is finally transmitted to the integrated rod 11 through the connecting rod 6014, thereby realizing the longitudinal displacement of the integrated rod 11.
[0040] like Figure 4 and Figure 5 As shown, the movement range and displacement of the integrated rod 11 can be accurately controlled by the limiting sleeve 609 and other limiting mechanisms; and the structure is simple and the response is rapid.
[0041] like Figure 4 and Figure 5As shown, a first gear 6017 is coaxially connected to the middle of the rotating shaft 6011, a second gear 6018 is provided on one side of the first gear 6017, a mounting shaft 6019 is coaxially connected to the middle of the second gear 6018, an identification pointer 6020 is provided on the mounting shaft 6019, an indicator sign 6021 is provided in the control cavity of the mounting base 1, the identification pointer 6020 matches the indicator sign 6021, the indicator sign 6021 is marked with the words closed and open, and the first gear 6017 is rotated in coordination with the rotation of the rotating shaft 6011 through the connecting rod control assembly 6, and the second gear 6018 is rotated together, so that the identification pointer 6020 points to the font on the indicator sign 6021.
[0042] like Figure 4 and Figure 5 As shown, the rotation of the rotating shaft 6011 drives the first gear 6017 to rotate; due to the coaxial connection between the first gear 6017 and the second gear 6018, the rotation of the first gear 6017 will drive the second gear 6018 to rotate; the second gear 6018 is connected to the mounting shaft 6019, so the rotation of the second gear 6018 will drive the mounting shaft 6019 to rotate; the identification pointer 6020 on the mounting shaft 6019 moves with the rotation, pointing to the word "closed" or "open" on the indicator sign 6021 in the control cavity of the mounting base 1; the connecting rod control assembly 6 controls the rotation angle of the rotating shaft 6011, thereby controlling which word the identification pointer 6020 points to, thereby realizing the indication function.
[0043] like Figure 4 and Figure 5 As shown, the pointer points to "closed" or "open", which intuitively indicates the status of the device and is easy to understand and operate; it has a purely mechanical structure, and its reliability is usually higher than that of electronic indicating devices, and it is not easily affected by electromagnetic interference or power failure; and it relies entirely on mechanical transmission, does not require electricity supply, and is energy-saving and environmentally friendly.
[0044] like Figure 3 As shown, an observation window 12 communicating with the control cavity is provided on one side surface of the mounting base 1 , the indicator plate 6021 is located in the observation window 12 , and a protective glass 13 is provided inside the observation window 12 .
[0045] like Figure 3 As shown, an observation window 12 is opened on the mounting base 1, and the window is communicated with the control cavity inside the device; the indicator sign 6021 is placed inside the control cavity, and a protective glass 13 is installed on the inside of the observation window 12 to protect the indicator sign 6021 and prevent the external environment from affecting the indicator sign 6021; through the observation window 12, the user can intuitively see the information on the indicator sign 6021, such as status indication, warning information, etc.
[0046] like Figure 3As shown, in general, the user can directly see the status information displayed on the indicator sign 6021 through the observation window 12 without opening the device casing, and can quickly and conveniently understand the device operating status; moreover; the protective glass 13 can effectively prevent damage to the indicator sign 6021 by external environmental factors such as dust and water vapor, and prevent users from accidentally touching the indicator sign 6021; it also prevents internal parts from accidentally popping out and injuring people.
[0047] Working principle: When in use, the user first turns the hand wheel 602, and the rotation of the hand wheel 602 drives the coaxial special-shaped shaft 606 to rotate; the special-shaped shaft 606 has a unique concave design in the middle, so that the rotational motion is converted into the longitudinal displacement of the concave part 608; this longitudinal displacement is transmitted to the limit slide 6010 through the limit sleeve 609; the limit sleeve 609 limits the displacement range of the special-shaped shaft 606; the displacement of the limit slide 6010 causes it to rotate around the rotating shaft 6011; the rotational motion of the limit slide 6010 is transmitted to the limit slide 6010 through the sliding sleeve The movement of the L-shaped special-shaped block 6013 is finally transmitted to the integrated rod 11 through the connecting rod 6014, realizing the longitudinal displacement of the integrated rod 11, and driving the insulating pull rod 4 to slide in the fixed sleeve 3; the movement of the insulating pull rod 4 directly controls the connection or disconnection between the moving contact 5 and the static contact; when the insulating pull rod 4 pushes the moving contact 5 to contact the static contact, the circuit is closed; the pull rod is pulled back, the moving contact 5 is separated from the static contact, and the circuit is disconnected; the whole process relies on mechanical transmission, which is simple and reliable.
[0048] At the same time, the rotation of the rotating shaft 6011 drives the first gear 6017 to rotate; due to the coaxial connection between the first gear 6017 and the second gear 6018, the rotation of the first gear 6017 will drive the second gear 6018 to rotate; the second gear 6018 is connected to the mounting shaft 6019, so the rotation of the second gear 6018 will drive the mounting shaft 6019 to rotate; the identification pointer 6020 on the mounting shaft 6019 moves with the rotation, pointing to the words "closed" or "open" on the indicator sign 6021 in the control cavity of the mounting base 1; and the pointing state of the indicator sign 6021 is observed through the observation window 12, thereby realizing the indication function.
[0049] When the hand wheel 602 is rotated to a specific position and the socket is aligned with a certain mounting hole 605, the insertion rod 603 can be inserted, thereby locking the hand wheel 602 and the positioning ring 604; this locking mechanism ensures that the operation can only be performed at a preset, safe angle, effectively preventing accidental operation.
[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
