[0038] Please see the attached Figure 1-5 In one embodiment, the present invention provides a device for replacing the moving contact piece 530 of a high-voltage switch, comprising a mounting mechanism 10, a pin receiving assembly 20, and a pin adjusting assembly 30. First of all, it should be noted that the longitudinal direction in this application refers to the extension direction of the moving contact piece 530, and the transverse direction refers to the width direction of the moving contact piece 530; and this is different from the prior art for high-voltage disconnecting switches such as GW16A and 17A, which are often repaired at high altitudes. The high-voltage disconnecting switches contain springs inside, and the replacement of the moving contact piece 530 alone often takes a long time, with many processes, and the knife switch opening angles are different. This makes it very difficult to operate at high altitudes, and it is easy to drop parts, affecting work efficiency. The present application solves the above-mentioned defects in the prior art by providing a device for replacing the moving contact piece 530 of a high-voltage switch. The details are as follows:

[0039] The mounting mechanism 10 is used to be fixedly connected to the conductive arm 520 of the high-voltage switch, and the mounting mechanism 10 has an operating space for placing the moving contact piece 530 of the high-voltage switch; the mounting mechanism 10 has a plurality of pin rod through holes extending vertically, and the plurality of pin rod through holes are arranged one by one directly below the pin rod 510 of the moving contact piece 530, the pin rod storage assembly 20 is fixed to the outside of the bottom of the mounting mechanism 10, and the pin rod storage assembly 20 has a storage channel 211 for storing the pin rod 510, and the storage channel 211 is arranged correspondingly at the pin rod through hole; the pin rod adjustment assembly 30 is arranged at a longitudinal interval on one side of the pin rod through hole, and is movably connected to the mounting mechanism 10 along the longitudinal direction.

[0040] Specifically, the high-voltage switch moving contact piece 530 replacement device in the present application includes a mounting mechanism 10, a pin rod receiving assembly 20 and a pin rod adjusting assembly 30. The mounting mechanism 10 serves as a carrier of the entire replacement device and is used to be fixedly connected to the conductive arm 520 of the high-voltage switch. After being fixed on the conductive arm 520, the entire moving contact piece 530 can be placed in the operating space of the mounting mechanism 10 for easy operation. Some auxiliary tools and the storage of parts replacement can be completed in the operating space; and the pin rod receiving assembly 20 is used to temporarily store the movable contact piece 530. The pin rod 510 is removed from the contact piece 530, so it has a storage channel 211 for the pin rod 510 to be temporarily stored directly in the storage channel 211 after being removed; the pin rod adjustment assembly 30 is used to adjust the position of the pin rod 510. Since the pin rod 510 is easily offset longitudinally when being removed at different knife switch opening angles, it cannot fall directly into the storage channel 211. Therefore, the pin rod adjustment assembly 30 can be used to movably assist in pushing, thereby assisting in adjusting the position of the pin rod 510 until it falls vertically into the storage channel 211.

[0041] In which, the mounting mechanism 10 has a plurality of pin rod through holes (not shown) extending vertically, and the pin rod through holes are used for the pin rod 510 removed from the movable contact piece 530 to pass through, so that it can fall into the storage channel 211. Therefore, the pin rod through holes need to be arranged one by one directly below the pin rod 510 of the movable contact piece 530. The one-to-one corresponding arrangement here means that the pin rod through holes are consistent in size with the pin rod 510 and are arranged coaxially, and the pin rod receiving assembly 20 is fixed to the outside of the bottom of the mounting mechanism 10, so that the storage channel 211 in the pin rod receiving assembly 20 is correspondingly arranged directly below the pin rod through hole, and the pin rod 510 removed from the movable contact piece 530 first passes through the pin rod through hole and then falls into the storage channel 211; the pin rod adjustment assembly 30 is connected to the mounting mechanism 10 and is movably arranged in the longitudinal direction to help the pin rod 510 to align with the pin rod through hole for easy falling.

[0042] As a preferred embodiment of the present invention, the mounting mechanism 10 includes a housing 110 and a fixing block 120. One end of the housing 110 is provided with a connecting block 111 protruding outward in the longitudinal direction.

[0043] The housing 110 has the operating space, and the bottom of the housing 110 is provided with four pin rod through holes distributed in a matrix shape. The pin rod adjustment assembly 30 is movably connected to the bottom of the housing 110 along the longitudinal direction.

[0044] It should be noted that the housing 110 is used to wrap the movable contact piece 530 so that the movable contact piece 530 is placed in the operating space of the housing 110. When replacing the movable contact piece 530, even if some parts fall, they will fall into the housing 110 and will not fall out from a high altitude. The fixing block 120 is used to fix the housing 110 on the conductive arm 520 of the high-voltage switch, and a connecting block 111 is formed at one end of the housing 110 protruding outward in the longitudinal direction. The connecting block 111 is used to cooperate with the fixing block 120 to perform a sleeve connection; wherein, since the conductive arm 520 is cylindrical, Therefore, a first semicircular groove with an upward opening is formed in the recess of the connecting block 111, and a second semicircular groove with a downward opening is formed in the recess of the fixing block 120. In this way, the circular space enclosed by the first semicircular groove and the second semicircular groove matches the size of the conductive arm 520. During installation, the first semicircular groove of the connecting block 111 of the shell 110 is clamped under the conductive arm 520, and then the fixing block 120 is correspondingly clamped on the conductive arm 520. The shell 110 can be installed by fixing it with bolts, so that the connecting blocks 111 are surrounded and fixedly connected with each other through the fixing block 120 to be sleeved on the conductive arm 520.

[0045] It is worth mentioning that the pin through hole is opened at the bottom of the shell 110. In a preferred embodiment, there are two movable contact pieces 530 arranged opposite to each other in the horizontal direction, and each movable contact piece 530 has two pins 510, one for connecting with the conductive arm 520, and the other for connecting with the spring liner 540. Therefore, the number of pin through holes is four, and the four pin through holes are distributed in a matrix according to the arrangement position of the pins 510, so as to correspond to the pins 510.

[0046] As a preferred embodiment of the present invention, the pin rod storage assembly 20 includes two pin rod storage units spaced apart in the longitudinal direction, each of the pin rod storage units includes two pin sleeves 210 arranged opposite to each other in the transverse direction, the pin sleeves 210 are fixed to the bottom outer side of the shell 110, and each of the pin sleeves 210 has the storage channel 211.

[0047] It should be noted that, since the present application is a preferred embodiment, the number of pin holes corresponds to four pins 510, so the pin storage assembly 20 also includes two pin storage units spaced apart in the longitudinal direction, and each of the pin storage units also includes two pin sleeves 210 arranged opposite to each other in the transverse direction, and the pin sleeves 210 are used to accommodate the pins 510, so as to ensure that a pin sleeve 210 is correspondingly provided under each of the pin holes, wherein a small hole is usually provided at the bottom of the pin sleeve 210, so that when the pin 510 needs to be installed, a round rod can be used to push the pin 510 upward from the small hole to the original installation position, and then a retaining ring can be installed to fix the pin 510 to complete the restoration.

[0048] As a preferred embodiment of the present invention, the pin rod adjustment assembly 30 includes two push plates 310 spaced apart in the transverse direction, and the bottom of the housing 110 is provided with two slide groove groups spaced apart in the transverse direction, each of which includes two longitudinal slide grooves 112 spaced apart in the transverse direction, wherein:

[0049] Both sides of each push plate 310 are provided with sliders 311 protruding downwards. The two sliders 311 of each push plate 310 are respectively connected to the longitudinal slide grooves 112 of the slide groove group and are movably arranged in the longitudinal direction.

[0050] It is worth mentioning that the push plate 310 is used to assist the offset pin rod 510 to adjust its position. Therefore, in order to facilitate the movement of the push plate 310, two slide groove groups arranged at intervals along the transverse direction are opened at the bottom of the shell 110, and each of the slide groove groups is used to correspond to a movable connection of the push rod; wherein, each of the slide groove groups includes two longitudinal slide grooves 112 arranged opposite to each other along the transverse direction, and sliders 311 are formed on both sides of the push plate 310, and the two sliders 311 are respectively arranged in the longitudinal slide groove 112 of a slide groove group to guide sliding through the longitudinal slide groove 112, so that the push plate 310 is movably arranged in the longitudinal direction.

[0051] As a preferred embodiment of the present invention, it also includes a spring limiting assembly 40 for fixing the spring liner 540 of the high-voltage switch, the spring limiting assembly 40 includes two spring limiting units arranged opposite to each other in the transverse direction, each of the spring limiting units includes a spring clamping plate 410 and a fixing pad 420, wherein,

[0052] The spring clip 410 has a placement space for the spring liner 540. A first bolt hole is formed on the side wall of the housing 110. A second bolt hole corresponding to the first bolt hole is formed on one side of the spring clip 410. The spring clip 410 is connected to the housing 110 by bolts passing through the first and second bolt holes in sequence. The other side of the spring clip 410 is used for abutting the spring liner 540.

[0053] The fixing block 420 is connected to the bottom of the housing 110 and is used to provide padding for the spring liner 540 .

[0054] It is worth noting that since there are spring liners 540 installed and connected around the moving contact piece 530, the spring liners 540 will be slightly deformed when the moving contact piece 530 is replaced. Therefore, a spring limiting assembly 40 is required to temporarily fix the spring liners 540 before the moving contact piece 530 is installed. The spring limiting assembly 40 includes two spring limiting units arranged opposite to each other in the transverse direction to respectively fix a spring liners 540, and each of the spring limiting units includes a spring clamping plate 410 and a fixed pad 420. The spring clamping plate 410 is used for temporarily supporting and connecting the spring liners 540 to compress the spring to prevent the spring in the spring liners 540 from stretching and affecting The installation of the moving contact piece 530 has a placement space for the spring liner 540, so that the spring liner 540 is installed in the spring clamp 410; and to facilitate the fixation of the spring clamp 410, the bolts can be passed through the side plate of the shell 110 and the side plate of the spring clamp 410 by bolt connection, so that one side of the spring clamp 410 is connected to the side plate of the shell 110, and the other side of the spring clamp 410 is used for temporary support of the spring in the spring liner 540, so that the spring temporarily remains in a compressed state; the spring pad is used for padding the spring liner 540, and it is installed between the spring liner 540 and the bottom of the shell 110.

[0055] Furthermore, each of the spring limiting units further includes a door-shaped fixing block 430 , the bottom end of the door-shaped fixing block 430 is fixedly connected to the housing 110 , and the top end of the door-shaped fixing block 430 is used to be pressed onto the top of the spring liner 540 .

[0056] It should be noted that the door-shaped fixing block 430 is used to press the spring liner 540 from the top, so it is door-shaped. The bottom end of the door-shaped fixing block 430 can be connected to the bottom of the shell 110 by bolts, and the middle space of the door shape is used for the installation of the spring liner 540. After installation, the top end of the door-shaped fixing block 430 can apply a downward pressing force to the spring liner 540, and the spring pad cooperates with each other to increase the spring limiting effect.

[0057] Furthermore, the pin rod storage unit near one end of the fixing block 120 also includes two pin guide sleeves 220 arranged at intervals along the transverse direction. The pin guide sleeves 220 are fixed to the inner side of the bottom of the shell 110 and are correspondingly arranged on the pin rod through hole.

[0058] It should be understood that if the pin rod 510 near the inner side (one end of the fixed block 120) is offset, it will be inconvenient to adjust. Therefore, a pin guide sleeve 220 can be set near the inner pin rod through hole to guide the inner pin rod 510 when it falls to avoid offset. Therefore, the pin guide sleeve 220 is fixed to the inner side of the bottom of the shell 110 and is correspondingly set on the inner pin rod through hole. The pin guide sleeve 220 is set here to be consistent in size with the pin rod through hole and the pin rod 510 and is coaxial with the inner pin rod through hole.

[0059] Furthermore, the pin rod adjustment assembly 30 also includes two push plate buckles 320 arranged at intervals along the transverse direction, the push plate buckles 320 are connected to the inner side of the bottom of the shell 110, and the push plate buckles 320 are arranged between the pin rod through hole and the longitudinal slide groove 112, and the push plate buckles 320 are provided with a slide running through the longitudinal direction, and one end of the push plate 310 passes through and extends out of the slide setting.

[0060] It should be noted that the push plate buckle 320 is used to press the push plate 310 to prevent the push plate 310 from falling. It is installed on the inner side of the bottom of the shell 110. A slide running through the longitudinal direction is provided inside the push plate buckle 320. The slide is used to guide the push plate 310 to slide while pressing the push plate 310. The push plate buckle 320 is arranged between the pin rod through hole and the longitudinal slide groove 112, so that after the slider 311 of the push plate 310 is correspondingly clamped in the longitudinal slide groove 112, a section of it passes through and extends out of the slide setting, and the slide and the pin rod through hole are the boosting space for pushing the pin rod 510.

[0061] Furthermore, one end of the push plate 310 close to the pin rod 510 is recessed to form an arc-shaped groove 312 with an opening facing the pin rod 510 .

[0062] It should be noted that the arc-shaped groove 312 can better match the cylindrical shape of the pin rod 510, thereby achieving a better effect when assisting.

[0063] The present application also provides a high-voltage switch, including a high-voltage switch body 50, wherein the high-voltage switch body 50 includes a conductive arm 520, a movable contact piece 530 and a spring liner 540, wherein the movable contact piece 530 is connected to the conductive arm 520 through a pin rod 510, and the spring liner 540 is connected to the outer side of the movable contact piece 530 through the pin rod 510.

This type of high-voltage switch body 50 specifically includes but is not limited to a conductive arm 520, a movable contact piece 530 and a spring liner 540. Its specific connection method is well known to those skilled in the art, so it will not be described in detail here. When performing replacement work, the mounting mechanism 10 of the high-voltage switch movable contact piece 530 replacement device can be first fixedly connected to the conductive arm 520, and then the movable contact piece 530 can be replaced accordingly.

[0065] To facilitate understanding by those skilled in the art, the specific operation process in a preferred embodiment is briefly described as follows:
