Description
TECHNICAL FIELD
[0001] The present application belongs to the technical field of low-voltage electrical apparatus, and particularly relates to a manual operation structure of an operating system of a switching device, and is especially suitable for a dual power automatic transfer switch. BACKGROUND
[0002] The dual power automatic transfer switch is widely used in modern power transmission and distribution line systems, especially in places such as hospitals, intelligent buildings, data centers, power plants, banks, and important infrastructures that need to maintain continuous power supply. During the operation of the dual power automatic transfer switch, the reliability of the transfer and the stability of the operation are directly related to the continuous power output state of the power transmission and distribution line. The dual power automatic transfer switch has two types: two-position automatic transfer switch and three-position automatic transfer switch. The two-position automatic transfer switch switches between the two states of the normally used side power being closed (while the standby side power being open) and the standby side power being closed (while the normally used side power being open), realizing the continuous, stable, and reliable power output of the power transmission and distribution line. In addition to the working states of the two-position automatic transfer switch, the three-position automatic transfer switch can also realize the state of the normally used side power and the standby side power being open at the same time (i.e., the double open state) and the locking of the open state.
[0003] The operating system, as the core component of the dual power automatic transfer switch, provides the kinetic energy for the position transfer of the automatic transfer switch and drives the contact system of the automatic transfer switch to switch between the normally used side power and the standby side power through the output part. The operating system of the two-position automatic transfer switch has two states, corresponding to the normally used side power closed position and the standby side power closed position, respectively. The operating system of the three-position automatic transfer switch has three states, corresponding to the normally used side power closed position, the standby side power closed position, and the double open position, respectively.
[0004] However, the three-position automatic transfer switch in the prior art has a locking mechanism at each of the normally used side, the standby side, and the double open position, and the locking mechanisms of the three positions do not interfere with each other, which may lead to the locking of only one position and the lack of locking of the other position, resulting in safety accidents caused by misoperation. On the other hand, the existing dual power automatic transfer switch has a double main shaft structure, which cannot meet the requirement of same side wiring. On the other hand, the existing dual power automatic transfer switch needs to be manually operated, which may lead to the failure of the switching operation when the labor is insufficient and the damage of the switch when the labor is excessive. SUMMARY
[0005] The present application aims at the defects of the prior art, and provides a manual operation structure of a switch device operation system, which can be used for switching between three states of a normally used side power closing (with a standby side power opening), a standby side power closing (with a normally used side power opening) and the normally used side power and the standby side power being both opened (i.e. double opening) of a double power automatic transfer switch, and can be locked in the corresponding position by a corresponding locking device when being kept in the terminal position after the three-position switching is completed, and the locking devices of the positions are associated with each other, so that the product is prevented from being misoperated, and the manual closing and opening can be performed without manual operation, the operation system of the double power automatic transfer switch has a modularized position layout of components, is compact in structure, convenient and fast in installation and maintenance, easy to operate and high in reliability.

[0069] As shown in FIG. 10, the standby side flip limiting linkage shaft A101' is located at the lower end of the arc-shaped long slot hole 103', and the standby side flip lever A1' is located at the maximum angle position of its clockwise rotation, and the core B01' of the standby side electromagnet B' is in the retracted state. Because the flip levers A1, A1' are linked with the slide plate 2 at the same time, the flip limiting linkage shaft A101 is located at the upper position of the arc-shaped long slot hole 103, and the normal use side flip lever A1 is located at the maximum angle position of its clockwise rotation, and the core B01 of the normal use side electromagnet B is in the extended state. Figure 16 As shown in FIG. 10, the standby side flip limiting linkage shaft A101' is located at the lower end of the arc-shaped long slot hole 103', and the standby side flip lever A1' is located at the maximum angle position of its clockwise rotation, and the core B01' of the standby side electromagnet B' is in the retracted state. Because the flip levers A1, A1' are linked with the slide plate 2 at the same time, the flip limiting linkage shaft A101 is located at the upper position of the arc-shaped long slot hole 103, and the normal use side flip lever A1 is located at the maximum angle position of its clockwise rotation, and the core B01 of the normal use side electromagnet B is in the extended state. Figure 17 As shown in FIG. 10, the standby side flip limiting linkage shaft A101' is located at the lower end of the arc-shaped long slot hole 103', and the standby side flip lever A1' is located at the maximum angle position of its clockwise rotation, and the core B01' of the standby side electromagnet B' is in the retracted state. Because the flip levers A1, A1' are linked with the slide plate 2 at the same time, the flip limiting linkage shaft A101 is located at the upper position of the arc-shaped long slot hole 103, and the normal use side flip lever A1 is located at the maximum angle position of its clockwise rotation, and the core B01 of the normal use side electromagnet B is in the extended state.
[0070] As shown in FIG. 10, the standby side flip limiting linkage shaft A101' is located at the lower end of the arc-shaped long slot hole 103', and the standby side flip lever A1' is located at the maximum angle position of its clockwise rotation, and the core B01' of the standby side electromagnet B' is in the retracted state. Because the flip levers A1, A1' are linked with the slide plate 2 at the same time, the flip limiting linkage shaft A101 is located at the upper position of the arc-shaped long slot hole 103, and the normal use side flip lever A1 is located at the maximum angle position of its clockwise rotation, and the core B01 of the normal use side electromagnet B is in the extended state. Figure 17As shown, the line connecting the rotation centers of the commonly used side flip-limit linkage shaft A101 and the commonly used side rotation linkage shaft C1 is located above the rotation center O of the commonly used side rotating lever C, and the line connecting the rotation centers of the spare side flip-limit linkage shaft A101' and the spare side rotation linkage shaft C1' is located below the rotation center O' of the spare side rotating lever C'. At this time, the rotating lever C is subjected to the spring force of the main spring D and receives a counterclockwise torque, and the rotating lever C' is subjected to the spring force of the main spring D' and receives a counterclockwise torque. The normal line a of the contact surface between the linkage limiting part 301a0101 in the commonly used side linkage slot 301a01 on the mounting bushing 301 and the commonly used side rotation linkage shaft C1 points to the rotation center O of the commonly used side rotating lever C. In this embodiment, the electromagnet B on the commonly used side and the electromagnet on the spare side... With a longer stroke, the commonly used side's flip-limit linkage shaft A101 is located at the upper top of the arc-shaped long slot 103 on the commonly used side, and the spare side's flip-limit linkage shaft A101' is located at the lower top of the arc-shaped long slot 103' on the spare side, thus achieving limitation. Simultaneously, the strokes of the commonly used side's electromagnet B and the spare side's electromagnet B' can also be used to directly limit the positions of the commonly used side's flip-limit linkage shaft A101 and the spare side's flip-limit linkage shaft A101'. Specifically, the strokes of the commonly used side's electromagnet B and the spare side's electromagnet B' are designed to be relatively short, and their corresponding iron cores B01' and B01 can only move to their lowest point before stopping, thereby achieving the purpose of limiting the positions of the corresponding commonly used side's flip-limit linkage shaft A101 and the spare side's flip-limit linkage shaft A101'. Under the combined action of the rotating levers C and C', as shown in the attached... Figure 18 As shown, the mounting sleeve 301 is located at its maximum clockwise rotation position (i.e., the standby power supply closed position). The double-position linkage part 301b of the mounting sleeve 301 is located inside the waist-shaped limiting hole F101 on the limiting plate F1, and the unlocking limiting shaft linkage part F102 on the limiting plate F1 is located to the left of the unlocking limiting shaft F502; the iron core F501 of the unlocking electromagnet F5 is in the extended state. The double-position linkage part 301b is a columnar protrusion on the outer circumference of the mounting sleeve 301, and the unlocking limiting shaft linkage part F102 is a boss in the hole on the limiting plate F1. Due to the spring force of the toggle lever 4's return springs 4a and 4a', the right side of the sliding plate linkage part 401 of the toggle lever 4 contacts the driven shaft 2b on the sliding plate 2 as shown in the attached figure. Figure 19 As shown, in this embodiment, the sliding plate linkage part 401 is a horizontal hole.
[0071] As attached Figure 19As shown, due to the reset action of the unlocking lever return spring F3, the flipping limit linkage shaft A101 of the unlocking lever F2 is located at the leftmost position of the unlocking waist-shaped elongated hole one F201, and the unlocking limit shaft F502 is located at the rightmost position of the unlocking waist-shaped elongated hole two F202; due to the reset action of the unlocking lever return spring F3', the flipping limit linkage shaft A101' of the unlocking lever F2' is located at the rightmost position of the unlocking waist-shaped elongated hole one F201', and the unlocking limit shaft F502 is located at the rightmost position of its unlocking waist-shaped elongated hole two F202'.
[0072] When the standby power supply switches from the closed position to the open position: Rotate lever 4 counterclockwise. Lever 4 then moves slide plate 2 from right to left. Slide plate 2, in turn, moves flip levers A1 and A1' counterclockwise simultaneously. Alternatively, energize electromagnet B on the normal power supply side, causing core B01 to retract, which in turn pulls lever A3 and moves flip lever A1 counterclockwise. During this rotation, flip lever A1, via slide plate 2, moves flip lever A1' counterclockwise as well. (See attached diagram) Figure 20 As shown.
[0073] When the flip lever A1 rotates until the line connecting the rotation centers of the flip limit linkage shaft A101 and the rotation linkage shaft C1 passes through the rotation center O of the corresponding rotating lever C, the flip lever A1' also rotates until the line connecting the flip limit linkage shaft A101' and the rotation linkage shaft C1' passes through the rotation center O' of the rotating lever C'. The main spring D on the normally used side does not generate a rotational torque on the corresponding rotating lever C, thus placing the corresponding rotating lever C in a dead position. Similarly, the main spring D' on the spare side does not generate a rotational torque on the corresponding rotating lever C', thus placing the corresponding rotating lever C' in a dead position. (See attached diagram) Figure 21 As shown.
[0074] As attached Figure 22 As shown, the flip levers A1 and A1' continue to rotate counterclockwise until they reach their positions. At this point, the line connecting the rotation centers of the flip limit linkage shaft A101 and the rotation linkage shaft C1 is below the rotation center O of the rotating lever C, and the line connecting the flip limit linkage shaft A101' and the rotation linkage shaft C1' is above the rotation center O' of the rotating lever C'. The rotating lever C is subjected to the spring force of the main spring D and a clockwise torque, while the rotating lever C' is subjected to the spring force of the main spring D' and a clockwise torque. Clockwise torque; the rotating lever C rotates clockwise, causing the rotating linkage shaft C1 to slide inside the linkage slot 301a01, and the rotating lever C' rotates clockwise, causing the rotating linkage shaft C'1 to slide inside the linkage slot 301a01'. During the sliding process, the rotating linkage shaft C and the rotating linkage shaft C' are linked to the mounting sleeve 301 to rotate counterclockwise. The counterclockwise rotation of the mounting sleeve 301 is linked to the output shaft 302 to also output counterclockwise rotation, thereby tripping the backup power supply.
[0075] As shown in the accompanying Figure 23 clockwise rotation of the dial lever 4, the unlocking lever F2 is unlocked, and the unlocking lever F2 is slid away from the center of the operating system. When the dial lever 4 is released, the dial lever 4 is reset clockwise under the action of the dial lever return spring 4a', the unlocking lever F2 is reset to the center of the operating system under the action of the unlocking lever return spring F3, and the unlocking lever F2 is finally below the unlocking lever touch part 403 of the dial lever 4 as shown in the accompanying Figure 24 .
[0076] When the mounting sleeve 301 is counterclockwise rotated, the double-position linkage part 301b of the mounting sleeve 301 links the waist-shaped limiting hole F101 on the limiting plate F1 and makes the limiting plate F1 counterclockwise rotate. During the counterclockwise rotation of the limiting plate F1, the unlocking limiting shaft linkage part F102 of the limiting plate F1 is limited by the unlocking limiting shaft F502 (at this time, the unlocking limiting shaft linkage part F102 is located on the left side of the unlocking limiting shaft F502), and after the limiting plate F1 is limited, the waist-shaped limiting hole F101 reversely limits the counterclockwise rotation of the mounting sleeve 301 through the double-position linkage part 301b. At this time, the line connecting the rotation center of the flip limiting linkage shaft A101 and the rotation linkage shaft C1 is still below the rotation center O of the rotation lever C, the line connecting the rotation center of the flip limiting linkage shaft A101' and the rotation linkage shaft C1' is still above the rotation center O' of the rotation lever C', the rotation lever C is subjected to the spring force of the main spring D and the clockwise torque, and the rotation lever C' is subjected to the spring force of the main spring D' and the clockwise torque as shown in the accompanying Figure 25a and 25b .
[0077] After the mounting sleeve 301 is limited by the unlocking limiting shaft F502 through the limiting plate F1, the operating system is in a state that neither the standby side power supply nor the commonly used side power supply is connected, and this state is the double-position state of the double power automatic transfer switch.
[0078] When the dual split position state is converted to the standby side power closing connection: in this state, the electromagnet B' of the standby side is energized, the core B01' is retracted, or the clockwise rotating lever 4 is rotated and the flip lever A1, A1' is rotated clockwise; after rotating to the position, the connecting line between the flip limiting linkage shaft A101 and the rotating center of the rotating linkage shaft C1 is above the rotating center O of the rotating lever C, the connecting line between the flip limiting linkage shaft A101' and the rotating linkage shaft C1' is below the rotating center O' of the rotating lever C', the rotating levers C, C' rotate counterclockwise due to the counterclockwise torque, they rotate clockwise through the rotating linkage shaft C1, C1' connecting sleeve 301, thereby realizing the standby side power closing of the operating system as shown in the accompanying Figure 19 .
