Description

Technical Field

[0001] This utility model relates to a universal plug converter for high-voltage circuit breakers, belonging to the technical field of high-voltage circuit breakers. Background Technology

[0002] The high-voltage circuit breaker plug is a crucial part of the connection between the circuit breaker and the high-voltage cabinet, playing a vital role in the safe and stable operation of the high-voltage cabinet. Due to differences in manufacturers, the pin definitions on the plug of high-voltage circuit breakers vary. Common 10kV high-voltage circuit breakers typically use 58-pin plugs and sockets. However, because manufacturers differ in their circuit breaker control principles and components, the pin definitions of the plug and socket may differ. Since our company has many branch factories established at different times, the circuit breakers we use also vary. Aside from the incompatibility due to different circuit breaker sizes, most circuit breakers are the same size, but the pin definitions differ.

[0003] To promote cost reduction and efficiency improvement, and to lower spare parts costs, each branch factory needs to stock spare parts for its circuit breakers, which requires a significant amount of procurement expenses. If a universal plug adapter could be developed, substantial spare parts costs could be saved. However, due to different pin configurations, these adapters cannot be used immediately; they must be rewired after checking the drawings, which is time-consuming and labor-intensive, and improper modification can lead to equipment accidents. Therefore, we have proposed a universal plug adapter for high-voltage circuit breakers. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a universal plug converter for high-voltage circuit breakers, which quickly switches the input and output points through the conversion plug, making it easy for operators to quickly get started and operate. A circuit breaker can be modified and put into use in a short time, thus realizing the universality of the circuit breaker.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: a universal plug converter for high-voltage circuit breakers, including a converter plug and a converter socket, which are electrically connected. The converter plug includes a converter plug body with a plurality of spaced-apart converter plug pins, which correspond to the plug pins of the standard plug of the high-voltage switchgear circuit breaker. The converter socket includes a converter socket body with a standard socket unit on the top surface, which is the same as the socket socket of the high-voltage switchgear circuit breaker. A conversion socket unit is provided on one side of the converter socket body, and a conversion insert unit is inserted into the conversion socket unit, which switches the input and output points on the conversion socket unit.

[0006] The standard socket unit includes several standard socket groups, which are evenly spaced along the length of the adapter body; each standard socket group includes multiple standard sockets evenly spaced along the width of the adapter body.

[0007] The adapter socket unit includes several adapter socket groups, which are evenly spaced along the length of the adapter socket body. Each adapter socket group includes multiple adapter sockets: an adapter input socket and an adapter output socket. The adapter input socket and the adapter output socket are used in pairs. The adapter input socket and the standard socket are electrically connected via connectors. The adapter output socket is electrically connected to the adapter socket via connecting wires.

[0008] The paired input and output conversion sockets are numbered, and the numbering is located on the conversion socket body; the output conversion socket is coated with a pigment layer.

[0009] The connector includes a socket connector, and the conversion input socket and the standard socket are electrically connected through the socket connector. The socket connector is wrapped with heat shrink tubing.

[0010] The conversion insert unit includes multiple conversion inserts, with two pins of each conversion insert inserted into a paired conversion input jack and conversion output jack, thereby electrically connecting the conversion output jack and conversion input jack.

[0011] The outer sides of the two pins of the conversion plug are symmetrically provided with protrusions, and the inner walls of the conversion output socket and conversion input socket are respectively provided with grooves, with the protrusions located in the grooves on the corresponding sides.

[0012] Compared with the prior art, the advantages of this utility model are as follows: A universal plug converter for high-voltage circuit breakers, without changing the original circuit breaker and high-voltage cabinet wiring, allows for quick insertion of the conversion plug into the conversion socket to switch the input and output points of the conversion socket. The conversion output sockets are marked with different colors and the conversion socket groups are numbered, which can quickly find the corresponding input and output points, making it easy for operators to quickly start the modification, shortening the modification time and enabling it to be put into use online. It maximizes the versatility of circuit breakers in electrical circuits and greatly reduces the cost of spare parts procurement and storage. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 , 2 As shown in Figures 1 and 3, a universal plug converter for high-voltage circuit breakers in this embodiment includes a converter plug 1 and a converter socket 3, which are electrically connected by a connecting wire 2. The converter plug 1 includes a converter plug body 1.2, on which are arranged a plurality of spaced-apart converter plug pins 1.1, the number of which is the same as the number of pins on the standard plug of the high-voltage switchgear circuit breaker. The converter socket 3 includes a converter socket body, on which a standard socket unit is opened on the top surface. The standard socket unit is the same as the socket socket of the high-voltage switchgear circuit breaker, allowing the standard socket unit to be electrically connected to the circuit breaker trolley plug. A conversion socket unit is opened on one side of the converter socket body, on which a conversion insert unit is inserted. The conversion insert unit switches the input and output points on the conversion socket unit, enabling rapid adjustment of the circuit breaker.

[0022] The standard socket unit includes several standard socket groups, which are evenly spaced along the length of the adapter body. Each standard socket group includes three standard sockets 3.2, which are evenly spaced along the width of the adapter body 3.1.

[0023] The adapter socket unit includes several adapter socket groups, which are evenly spaced along the length of the adapter socket body. Each adapter socket group includes six adapter sockets (3.3) evenly distributed along the height of the adapter socket body: three input sockets and three output sockets. The input sockets and output sockets are used in pairs. The input sockets are electrically connected to the standard sockets via connectors. The output sockets are color-coded to distinguish them from the input sockets and prevent incorrect insertion. The output sockets are electrically connected to the adapter socket via connecting wires.

[0024] like Figure 6 As shown, the above-mentioned wiring components include a socket connector, which is soldered between the conversion input socket and the standard socket. The socket connector is wrapped with heat-shrink tubing 5 for insulation to prevent short circuits.

[0025] The aforementioned conversion insert unit includes multiple conversion inserts 4, which are inserted into corresponding conversion sockets as required. The two pins 4.1 of the conversion insert 4 are inserted into paired conversion input and conversion output sockets, ensuring effective electrical connection between the conversion output and conversion input sockets. Symmetrical protrusions are provided on the outer surfaces of the two pins of the conversion insert, and grooves are provided on the inner walls of the conversion output and conversion input sockets. The protrusions are located within the corresponding grooves, ensuring that the conversion inserts will not detach from the conversion input and conversion output sockets after insertion, thus guaranteeing the safe operation of the circuit breaker.

[0026] like Figure 4 , 5 As shown, the adapter connectors come in two types: shorting tab type and flat wire type. The flat wire type can span a greater distance. The pins, input jacks, output jacks, and sockets of the adapter connector are all made of copper.

[0027] The paired input and output adapter jacks are all marked with numbers. The input adapter jack and its corresponding output adapter jack share the same number, forming a set. The number is marked on the adapter plug itself.

[0028] This application, without altering the existing circuit breaker and high-voltage cabinet wiring, allows for quick switching of the input / output points of the conversion socket by inserting a conversion tab into the conversion socket. The conversion output sockets are marked with different colors and the conversion socket groups are numbered, enabling quick identification of the corresponding input / output points. This facilitates rapid modification by operators, shortens modification time, and allows for immediate online use. It maximizes the versatility of the circuit breaker in electrical circuits and significantly reduces spare parts procurement and storage costs.

[0029] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
