Description

Technical Field

[0001] This invention relates to the field of low-voltage electrical appliances, and more specifically to a steady-state mechanism and a high-speed mechanical switch including the steady-state mechanism. Background Technology

[0002] Hybrid solid-state circuit breakers effectively solve the problems of high losses, the need for cooling devices, and high costs associated with solid-state circuit breakers. They integrate high-speed mechanical switches and power semiconductors connected in parallel. When the circuit breaker closes, the power semiconductor connects first, followed by the high-speed mechanical switch. When a fault current is encountered, the high-speed mechanical switch opens first, followed by the power semiconductor, thus achieving zero arc generation during the opening and closing process of the high-speed mechanical switch. The high-speed mechanical switch includes a moving contact mechanism and steady-state mechanisms that hold the moving contact mechanism in the open and closed positions, respectively. Existing high-speed mechanical switches often suffer from the following problems:

[0003] 1. Existing high-speed mechanical switches have complex steady-state mechanisms and occupy a large space.

[0004] 2. The existing high-speed mechanical switch layout is not compact enough. Summary of the Invention

The energy storage connecting rods are in one-to-one correspondence with the energy storage shafts, and both ends of the energy storage connecting rods are rotatably connected to the energy storage shafts and the connecting shafts, respectively. The connecting shafts, energy storage connecting rods, and energy storage shafts are arranged to move synchronously.

[0008] The steady-state mechanism has three operating states that can be switched sequentially: a first steady state, a critical state, and a second steady state. When the steady-state mechanism is in the critical state, the energy storage spring stores energy to its maximum value. The energy storage spring is configured to store energy when the steady-state mechanism switches from the first steady state or the second steady state to the critical state, driven by the energy storage shaft, and to release energy and drive the energy storage shaft to slide when the steady-state mechanism switches from the critical state to the first steady state or the second steady state.

[0083] The following embodiments, in conjunction with the accompanying drawings, further illustrate specific implementations of the high-speed mechanical switch of the present invention. The high-speed mechanical switch of the present invention is not limited to the descriptions in the following embodiments.

[0084] The high-speed mechanical switch of the present invention is preferably applied to hybrid solid-state circuit breakers.

[0085] like Figure 1 , 2As shown in Figures 10, 14, and 22, the high-speed mechanical switch of the present invention has a height direction, a length direction, and a width direction, which are respectively direction d1, direction d2, and direction d3, and directions d1, d2, and d3 are perpendicular to each other.

[0086] like Figure 2 , 10 As shown in 14 and 22, the high-speed mechanical switch of the present invention includes a housing 100, a stationary contact group 200, and a moving contact mechanism 500, a closing coil 300, a closing coil 400, and a steady-state mechanism 600, all of which are disposed within the housing 100.

[0087] The stationary contact assembly 200 is fixedly mounted on the housing 100. At least the portion with stationary contacts is located inside the housing 100, while the remaining portion can be located inside the housing 100 or protrude outside the housing 100 as needed.

[0088] The moving contact mechanism 500 is configured to reciprocate along direction d1 and switch between a closed position and an open position to close and open with the stationary contact group 200 respectively; that is, the moving contact mechanism 500 has a closed position and an open position, and switches between the closed position and the open position by reciprocating along direction d1 to close and open with the stationary contact group 200.

[0089] Specifically, the stationary contact group 200 includes a first stationary contact 201 and a second stationary contact 202 arranged opposite to each other along direction d2. The moving contact 510 includes a moving contact bridge and moving contacts. Each end of the moving contact bridge is provided with a set of moving contacts. The two sets of moving contacts are arranged side by side and spaced apart along direction d2, respectively for cooperating with the first stationary contact 201 and the second stationary contact 202.

[0090] The closing coil 300 is used to drive the moving contact mechanism 500 to move to the closed position. That is, when the moving contact mechanism 500 is in the open position, the closing coil 300 can drive the moving contact mechanism 500 to move from the open position to the closed position.

[0091] The tripping coil 400 is used to drive the moving contact mechanism 500 to move to the open position. That is, when the moving contact mechanism 500 is in the closed position, the tripping coil 400 can drive the moving contact mechanism 500 to move from the closed position to the open position.

[0092] The steady-state mechanism 600 has three operating states that are sequentially switched as the moving contact mechanism 500 moves. In other words, the steady-state mechanism 600 switches its operating states as the moving contact mechanism 500 slides between the closed and open positions. The three operating states are, in sequence, a first steady state for holding the moving contact mechanism 500 in the closed position, a critical state, and a second steady state for holding the moving contact mechanism 500 in the open position. Correspondingly, the moving contact mechanism 500 has three positions—closed position, intermediate position, and open position—which correspond to the three operating states of the steady-state mechanism 600. That is, the steady-state mechanism 600 has three operating states: a first steady state, a critical state, and a second steady state. The first steady state, critical state, and second steady state can be switched sequentially in the order of first steady state → critical state → second steady state (the moving contact mechanism 500 moves from the closed position to the open position). When the moving contact mechanism 500 moves to the open position, the steady-state mechanism 600 switches its working state in this switching sequence (either the second steady state → critical state → first steady state). The working state of the steady-state mechanism 600 changes with the movement of the moving contact mechanism 500. In the first steady state, the steady-state mechanism 600 is used to keep the moving contact mechanism 500 in the closed position. In the second steady state, the steady-state mechanism 600 is used to keep the moving contact mechanism 500 in the open position. The critical state of the steady-state mechanism 600 is a temporary unstable state and a transitional working state that the steady-state mechanism 600 passes through when switching between the first and second steady states. The intermediate position of the moving contact mechanism 500 is an unstable position and a transitional position that the moving contact mechanism 500 passes through when switching between the closed and open positions.

[0093] like Figure 1 , 8 As shown in Figures 9 and 10, the housing 100 includes a first half-shell 101 and a second half-shell 130 that are fitted together, that is, the first half-shell 101 and the second half-shell 130 are fitted together to form the housing 100.

[0094] Specifically, the first half-shell 101 and the second half-shell 130 are fitted together relative to each other along direction d1.

[0095] Specifically, the second half-shell 130 is provided with a first stationary contact groove 131, a trip coil groove 133, and a second stationary contact groove 132. All three are located on the side of the second half-shell 130 facing the first half-shell 101. The first stationary contact groove 131 and the second stationary contact groove 132 are located on both sides of the trip coil groove 133 in the direction d2.

[0096] Specifically, the first half-shell 101 includes a front sidewall 102 and a rear sidewall 103 spaced apart along direction d3, a left sidewall 104 and a right sidewall 105 spaced apart along direction d2, and a bottom sidewall 109. The front sidewall 102, left sidewall 104, rear sidewall 103, and right sidewall 105 are sequentially connected, and one end of each of the front sidewall 102, left sidewall 104, rear sidewall 103, and right sidewall 105 is connected to the bottom sidewall 109 along direction d1. The bottom sidewall 109 is provided with a closing coil slot 107 for accommodating the closing coil 300.

[0097] like Figure 2-4 As shown in Figures 10-12, 14-17, 22-24, and 26, the steady-state mechanism 600 includes a connecting rod shaft 680 and two sets of energy storage mechanisms arranged side-by-side and spaced apart along direction d2. The two sets of energy storage mechanisms are a first energy storage mechanism 601 and a second energy storage mechanism 602. Each set of energy storage mechanisms includes a support 610, an energy storage shaft linearly slidable along direction d3 on the support 610, an energy storage spring 660, and an energy storage connecting rod. The connecting rod shaft 680 and the energy storage shaft are both parallel to direction d2, meaning that the axial directions of both the connecting rod shaft 680 and the energy storage shaft are parallel to direction d2. The energy storage connecting rods correspond one-to-one with the energy storage shafts; both ends of the energy storage connecting rods are rotatably connected to the energy storage shaft and the connecting rod shaft 680, respectively. The connecting rod shaft 680, the energy storage connecting rods, and the energy storage shaft are arranged synchronously, i.e., the connecting rod shaft 680, the energy storage connecting rods, and the energy storage shaft are linked together. The connecting shaft 680 is slidably disposed along direction d1 and its two ends are respectively slidably disposed on the supports 610 of the two sets of energy storage mechanisms. The connecting shaft 680 is used for transmission connection with the moving contact mechanism 500. The energy storage shaft cooperates with the energy storage spring 660. When the steady-state mechanism 600 is in the critical state, the energy storage spring 660 stores energy to its maximum value. The energy storage spring 660 is configured to store energy when the steady-state mechanism 600 switches from the first steady state or the second steady state to the critical state, and to release energy and drive the energy storage shaft to slide when the steady-state mechanism 600 switches from the critical state to the first steady state or the second steady state; that is, when the steady-state mechanism 600 switches from the first steady state or the second steady state to the critical state, the energy storage shaft drives the energy storage spring 660 to store energy; when the steady-state mechanism 600 switches from the critical state to the first steady state or the second steady state, the energy storage spring 660 releases energy and drives the energy storage shaft to slide. The steady-state mechanism 600 has a simple structure and stable and reliable operation. The energy storage mechanism can be assembled first, and then the energy storage mechanism can be assembled with the connecting rod shaft 680. The assembly is simple and efficient.

[0098] Furthermore, the two sets of energy storage mechanisms have identical structures; and / or, the two sets of energy storage mechanisms are symmetrically arranged. In the high-speed mechanical switch of the present invention, the two sets of energy storage mechanisms of the steady-state mechanism 600 preferably have identical structures and are symmetrically arranged.

[0099] Specifically, when the high-speed mechanical switch of the present invention is closed, the closing coil 300 operates and drives the moving contact mechanism 500 to slide towards the closed position; the moving contact mechanism 500 first slides from the open position to the intermediate position, and at the same time, the moving contact mechanism 500 drives the connecting rod shaft 680 to move synchronously. The connecting rod shaft 680 drives the energy storage shaft to slide through the energy storage connecting rod, and the energy storage shaft drives the energy storage spring 660 to store energy to the maximum value (at this time, the energy storage spring 660 reaches the dead point position), so that the steady-state mechanism 600 switches from the second steady state to the critical state; the moving contact mechanism 500 (in the closing coil) Under the influence of the inertia of the coil 300 and / or its own inertia, the coil 300 slides past the middle position and continues to slide towards the closed position. Simultaneously, the moving contact mechanism 500 drives the connecting rod shaft 680 to move synchronously. The connecting rod shaft 680 continues to slide, causing the energy storage spring to pass the dead point position. The energy storage spring releases energy, driving the energy storage shaft to slide in the opposite direction. The energy storage shaft, through the energy storage connecting rod and the connecting rod axis, applies a force to the moving contact mechanism 500, causing it to slide towards the closed position. When the moving contact mechanism 500 reaches the closed position, the steady-state mechanism 600 switches to the first steady state, holding the moving contact mechanism 500 in the closed position. When the connecting rod shaft 680 drives the energy storage spring 660 to store energy, the energy storage shaft slides along the first direction; when the energy storage spring 660 releases energy, it drives the energy storage shaft to slide along the second direction. The first direction and the second direction are opposite to each other.

[0100] Specifically, when the high-speed mechanical switch of the present invention is opened, the opening coil 400 operates and drives the moving contact mechanism 500 to slide towards the disconnected position; the moving contact mechanism 500 first slides from the closed position to the intermediate position, and at the same time, the moving contact mechanism 500 drives the connecting rod shaft 680 to move synchronously. The connecting rod shaft 680 drives the energy storage shaft to slide through the energy storage connecting rod, and the energy storage shaft drives the energy storage spring 660 to store energy to the maximum value (at this time, the energy storage spring 660 reaches the dead point position), so that the steady-state mechanism 600 switches from the first steady state to the critical state; the moving contact mechanism 500 (in the opening coil 400) (Under the influence of its own inertia) the energy storage spring slides past the middle position and continues to slide towards the closed position. Simultaneously, the moving contact mechanism 500 drives the connecting rod shaft 680 to move synchronously. The connecting rod shaft 680 continues to slide, causing the energy storage spring to pass the dead point position. The energy storage spring releases energy, driving the energy storage shaft to slide in the opposite direction. The energy storage shaft, through the energy storage connecting rod and the connecting rod shaft 680, applies a force to the moving contact mechanism 500, causing it to slide towards the open position. When the moving contact mechanism 500 reaches the open position, the steady-state mechanism 600 switches to the second steady state, holding the moving contact mechanism 500 in the open position. When the connecting rod shaft 680 drives the energy storage spring 660 to store energy, the energy storage shaft slides along the first direction; when the energy storage spring 660 releases energy, it drives the energy storage shaft to slide along the second direction. The first direction and the second direction are opposite to each other.

The arrangement of the steady-state mechanism 600 makes the layout of the high-speed mechanical switch more compact and reduces the size of the high-speed mechanical switch.

[0121] like Figure 10-13 The image shows a second embodiment of the steady-state mechanism 600.

[0122] A key difference between the steady-state mechanism 600 of the second embodiment and that of the first embodiment is that the steady-state mechanism 600 includes two connecting shafts 680, which are synchronously slidably arranged as a first connecting shaft 688 and a second connecting shaft 689; one end of the first energy storage connecting rod 651 is rotatably connected to the first energy storage shaft 631 and the other end is rotatably connected to the first connecting shaft 688; one end of the second energy storage connecting rod 652 is rotatably connected to the second energy storage shaft 632 and the other end is rotatably connected to the second connecting shaft 689.

[0129] Specifically, the energy storage spring 660 is a compression spring, with one end fixed and the other end cooperating with the corresponding energy storage shaft; the first energy storage part 691, the first energy storage shaft 631, the second energy storage shaft 632 and the second energy storage part 692 are arranged sequentially in the direction d3.

[0130] Specifically, the energy storage unit further includes an energy storage base 810 and an energy storage slider 820. The energy storage base 810 is fixedly mounted on the bracket 610, and the energy storage slider 820 is slidably mounted on the energy storage base 810.

[0132] During operation, the energy storage shaft slides along direction d3 and presses against the corresponding energy storage slider 820, which in turn presses against the corresponding energy storage spring 660 to store energy. After the steady-state mechanism 600 passes the critical state, the energy storage spring 660 begins to release energy and drives the corresponding energy storage slider 820 to slide along direction d3, which in turn drives the corresponding energy storage shaft to slide along direction d3.

[0133] Another key difference between the steady-state mechanism 600 of the third embodiment and the second embodiment is that the support 610 does not have a support end plate 613. The inner support plate 611 and the outer support plate 612 are connected together by a support bottom plate 614. That is, a pair of sides of the support bottom plate 614 are bent and connected to one side of the support inner plate 611 and the support outer plate 612, respectively.

[0137] Specifically, the energy storage mechanism includes two spring shafts, namely a first spring shaft 674 and a second spring shaft 675, which are fixedly mounted on the bracket 610. The first energy storage spring is sleeved on the first spring shaft 674, with one spring arm cooperating with the first energy storage shaft 631 and the other spring arm cooperating with the bracket 610. The second energy storage spring is sleeved on the second spring shaft 675, with one spring arm cooperating with the second energy storage shaft 632 and the other spring arm cooperating with the bracket 610. The axial directions of both the first spring shaft 674 and the second spring shaft 675 are parallel to direction d2.

The energy storage spring 660 includes a helix 663 and a first spring arm 661 and a second spring arm 662, which are respectively connected to the two axial ends of the helix 663. The first spring arm 661 cooperates with the energy storage shaft, and the second spring arm 662 cooperates with the bracket 610 (specifically, the bracket spring limiting part 622).

[0138] Another key difference between the steady-state mechanism 600 of the fourth embodiment and that of the third embodiment is that the bracket 610 does not have a bracket top side plate 619. The bracket 610 has two sets of bracket spring limiting parts 622, which are bent and connected to the inner side plate 611 or the outer side plate 612 of the bracket. Each of the two bracket spring limiting parts 622 is used to cooperate with one spring arm of each of the two energy storage springs 660; that is, one spring arm of each energy storage spring 660 cooperates with the corresponding energy storage shaft, and the other spring arm cooperates with the corresponding bracket spring limiting part 622. In this embodiment, both bracket spring limiting parts 622 are bent and connected to the inner side plate 611 of the bracket.
