Description

Technical Field

[0001] The utility model relates to the technical field of circuit breaker control, in particular to a modular linkage control mechanism applied to a primary-secondary deep fusion circuit breaker. Background Art

[0002] The primary and secondary fusion circuit breaker is a protection device composed of primary protection, secondary protection, fuses and electrical operating mechanisms. The primary and secondary fusion circuit breaker can realize the primary and secondary protection of the circuit at the same time, and can be flexibly set according to needs. Its main working principle is that when a circuit fault is found, the primary protection uses a protection relay to detect the fault signal, and cuts off the disconnector, grounding switch and other equipment through the electrical operating mechanism. For the secondary protection, it will be protected by various methods such as automatic protection, power failure protection, circuit breaker thermal protection, circuit breaker overload protection and short circuit protection.

[0003] In order to improve safety, the current primary and secondary fusion circuit breakers mostly use lateral control rods to control all isolation switches. However, because they mostly adopt an integrated fixed structure design, the number and position of the structures they control are very fixed, resulting in relatively single applicability, low modularity, and difficulty in subsequent maintenance. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the control of the current primary and secondary fusion circuit breaker adopts an integrated fixed structure design, which results in the number and position of the controlled structures being very fixed, resulting in relatively single applicability, low modularization, and great difficulty in subsequent maintenance.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a modular linkage control mechanism applied to a primary-secondary deep fusion circuit breaker, comprising a horizontal circuit breaker box, a first pole is fixedly mounted on the upper surface of the horizontal circuit breaker box, a front assembly frame is fixedly mounted on the side wall of the horizontal circuit breaker box, a second pole is fixedly mounted on the upper inclined surface of the front assembly frame, a modular central control box is fixedly mounted inside the front assembly frame, and a lateral control rod is movably mounted on the outer side surface of the front assembly frame.

[0006] The modular center control box includes a modular assembly box fixed by bolts inside the lower end opening of the front assembly frame, a longitudinal control column slidably assembled inside the guide hole at the upper end of the modular assembly box, a top assembly knife switch elastically mounted on the longitudinal control column, and an internal control bracket installed inside the modular assembly box.

[0007] The internal control bracket includes an internal control seat movably installed in the modular assembly box through a lateral control tube, an elastic control bracket fixed on the outer side of the internal control seat, a lateral linkage control gear fixed on the outer side of the internal control seat, an internal threaded guide seat meshing with the lateral linkage control gear, and an external threaded control shaft threadedly inserted in the internal threaded guide seat.

[0008] The bottom of the longitudinal control column is axially fixed to the upper end of the external thread control shaft, and the top of the longitudinal control column is fixedly assembled to the top assembly frame for elastically connecting the top assembly knife switch.

[0009] The lateral control rod is axially assembled with the internal control seat through a lateral transverse control shaft penetrating the internal control seat.

[0010] The top mounted knife switch is movably mounted inside the top mounting frame via mounting shafts on both sides, and lateral reset springs are fixed on both sides of the top surface of the top mounting frame. One side of the top mounted knife switch has an arc-shaped limit hook of an integral structure.

[0011] The beneficial effects of the utility model are:

[0012] (1) The modular linkage control mechanism of the utility model applied to the primary and secondary deep fusion circuit breaker adopts a modular design and can be freely replaced according to the position and quantity to be controlled, and has a wider scope of application;

[0013] (2) By adopting detachable modular assembly, it can be easily loaded and unloaded, greatly reducing the difficulty and cost of subsequent maintenance;

[0014] (3) The double separation design can greatly improve the separation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Figure 1 and Figure 2 A modular linkage control mechanism for a primary-secondary deep-integrated circuit breaker is shown, comprising a horizontal circuit breaker box 1, a first pole 2 is fixedly mounted on the upper surface of the horizontal circuit breaker box 1, a front assembly frame 3 is fixedly mounted on the side wall of the horizontal circuit breaker box 1, a second pole 4 is fixedly mounted on the upper inclined surface of the front assembly frame 3, a modular central control box 5 is fixedly mounted inside the front assembly frame 3, and a lateral control rod 6 is movably mounted on the outer surface of the front assembly frame 3.

[0021] Working principle: The lateral control lever 6 controls the modular central control box 5 by rotating, thereby adjusting the connection state of the first pole 2 and the second pole 4.

[0022] In order to cooperate with the modular assembly and fixation, the modular central control box 5 includes a modular assembly box 51 fixed by bolts to the inside of the lower end opening of the front assembly frame 3, a longitudinal control column 52 slidably assembled in the guide hole at the upper end of the modular assembly box 51, a top assembly knife switch 53 elastically mounted on the longitudinal control column 52, and an internal control bracket installed inside the modular assembly box 51.

[0023] In order to cooperate with the internal rotation control, the internal control bracket includes an internal control seat 55 movably installed in the modular assembly box 51 through a lateral control tube 54, an elastic control bracket 56 fixed on the outer side of the internal control seat 55, a lateral interlocking control gear 57 fixed on the outer side of the internal control seat 55, an internal threaded guide seat 58 meshing with the lateral interlocking control gear 57, and an external threaded control shaft 59 threadedly inserted in the internal threaded guide seat 58.

[0024] The function of the elastic control bracket 56 is to facilitate the elastic reset control of the internal control seat 55. The internal control seat 55 rotates, driving the lateral joint control gear 57 to rotate, and the lateral joint control gear 57 drives the internal thread guide seat 58 to rotate, thereby controlling the telescopic control of the external thread control shaft 59.

[0025] In order to cooperate with the top connection of the synchronous control box, the bottom of the longitudinal control column 52 is axially fixed to the upper end of the external threaded control shaft 59, and the top of the longitudinal control column 52 is fixedly assembled with the top assembly frame 7 for elastically connecting the top assembly knife switch 53.

[0026] In order to cooperate with the synchronous control, the lateral control rod 6 is axially assembled with the internal control seat 55 through the lateral transverse control shaft penetrating the internal control seat 55.

[0027] The cross section of the lateral transverse control shaft is a regular hexagonal structure, and there is no gap between the inner connecting surface of the internal control seat 55 .

[0028] In order to cooperate with elastic assembly and lateral limitation, the top assembly knife gate 53 is movably installed inside the top assembly frame 7 through the assembly axes on both sides. Lateral reset springs 8 are fixed on both sides of the top surface of the top assembly frame 7. One side of the top assembly knife gate 53 has an integrated arc-shaped limiting hook 9.

[0029] The arc-shaped limit barb 9 can be used to limit the installation of the connecting terminal on the side wall of the first pole 2. When the longitudinal control column 52 drives the top assembly frame 7 to descend, the arc-shaped limit barb 9 is first sleeved on the connecting terminal on the side wall of the first pole 2, and then the other side of the top assembly knife gate 53 is flipped downward to be assembled with the terminal at the top of the second pole 4. At this time, the arc-shaped limit barb 9 is flipped to the bottom of the connecting terminal on the side wall of the first pole 2. At this time, when the longitudinal control column 52 drives the top assembly frame 7 to rise, the other side of the top assembly knife gate 53 is separated from the terminal at the top of the second pole 4, and then the outer end of the top assembly knife gate 53 is flipped upward, so that the arc-shaped limit barb 9 is flipped to the outside of the connecting terminal on the side wall of the first pole 2, so that the top assembly knife gate 53 will be separated from the first pole 2 and the second pole 4 respectively.

[0030] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
