Description

Technical Field

[0002] When repairing a 10KV pole-mounted distribution transformer or performing a planned power outage for maintenance, it is difficult for workers to start work directly because there is no obvious disconnection point after the 10KV drop-out fuse is pulled out, which makes it difficult for workers to start work according to safety regulations. In addition, the distance between the upper and lower contacts of the drop-out fuse is usually only more than 300 mm, which is far lower than the 0.7 meter safety distance required for the 10KV voltage level, resulting in a great risk of electric shock when installing the grounding wire without completely cutting off the power. The limited operating space for workers on the pole-mounted distribution transformer stand, coupled with obstructed vision when installing the three-phase short-circuit grounding wire (such as direct sunlight on a sunny day or insufficient lighting at night), further increases the difficulty and danger of the operation.

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0046] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0047] Example 1

[0048] Reference Figure 1 , is the first embodiment of the present invention, which provides a 10KV pole-mounted distribution transformer grounding switch, including an opening and closing unit 100, including a base 101, a first insulator 102 arranged on the surface of the base 101, a second insulator 103 arranged corresponding to the first insulator 102, a driving rod 104 arranged on the inner side of the base 101, a third insulator 105 movably connected to the driving rod 104, and a flat iron 106 connected to the static contact C1 of the first insulator 102.

[0049] In this embodiment, the main function of the base 101 is to support other parts and provide a better platform for the linkage between various parts.

[0050] It should be noted that the first insulator 102 and the second insulator 103 are arranged opposite to each other, and contacts for contacting the knife switch are arranged on the top of the first insulator 102 and the second insulator 103; and the first insulator 102 and the second insulator 103 can be composite insulators, which are made of silicon and rubber; they have the advantages of light weight, good pollution resistance, anti-aging, easy installation and low maintenance cost.

[0051] Specifically, the driving rod 104 is arranged inside the base 101, and the driving rod 104 is movable inside the base 101; while the driving rod 104 is movable, it can drive the flat iron 106 to move through the third insulator 105, so that the flat iron 106 can contact or move away from the contact of the second insulator 103; thereby realizing the closing and opening of the knife switch.

[0052] Preferably, the driving rod 104 can drive the flat iron 106 to rotate through the third insulator 105 by reciprocating movement, so that the flat iron 106 can make an arc motion along the horizontal plane direction of the end of the second insulator 103, thereby controlling the flat iron 106 to contact or move away from the contact part of the second insulator 103.

[0053] It should be noted that one end of the driving rod 104 is provided with a buckle that can be used by the operator to drive the driving rod 104 to move using a tool, and the other end is connected to the driving device, thereby realizing the diversification of the knife switch closure; the use of an electric method can facilitate the operator to quickly open and close the knife switch; and the use of a manual end can ensure that when the driving device does not work normally, the operator can still complete the opening and closing of the knife switch.

[0054] In summary, the present invention can effectively avoid the risk of electric shock caused by insufficient safety distance between the upper and lower contacts of the 10KV drop-out fuse when installing a three-phase grounding wire; reduce the risk of high-altitude operations, greatly reduce the workload of operators, save a lot of working time, and effectively reduce the difficulty of work for operators.

[0055] Example 2

[0056] Reference Figures 1 to 4, which is the second embodiment of the present invention, includes: a connecting sleeve 107 is provided on the outer wall of the driving rod 104; the outer wall of the connecting sleeve 107 extends outwardly and is connected to a fixing plate 107a; the third insulator 105 includes a hinge seat 105a provided at one end thereof, and a push rod 105b provided at the other end of the third insulator 105; the driving rod 104 and the third insulator 105 are connected through the connecting sleeve 107.

[0057] In this embodiment, the connecting sleeve 107 is sleeved on the outside of the driving rod 104, and the connecting sleeve 107 and the driving rod 104 are connected; the connection between the connecting sleeve 107 and the driving rod 104 can be achieved by welding, clamping or fixing with bolts; the connecting sleeve 107 is connected to a fixing plate 107a along the outward extension direction of its axis.

[0058] Specifically, the material of the third insulator 105 is the same as that of the first insulator 102 and the second insulator 103 , and may also be a polycarbonate insulator, which has good mechanical strength, chemical corrosion resistance, good insulation performance, and good dimensional stability.

[0059] It should be noted that the end of the third insulator 105 and the connecting sleeve 107 are movable, and the driving rod 104 and the third insulator 105 are linked via the connecting sleeve 107 .

[0060] Furthermore, the flat iron 106 is hinged to the static contact C1 of the first insulator 102; the push rod 105b is an L-shaped structure, and the horizontal section of the push rod 105b penetrates the flat iron 106 and extends to the outside thereof.

[0061] In this embodiment, the flat iron 106 is hingedly rotated with the stationary contact C1 of the first insulator 102 ; the flat iron 106 flips along a direction perpendicular to the end face of the second insulator 103 ; and a notch is provided at the end of the flat iron 106 , which can be engaged with the moving contact C2 of the second insulator 103 .

[0062] It should be noted that the push rod 105b is an L-shaped structure, and the driving rod 104 can drive the third insulator 105 to move during the movement; and the vertical displacement of the end of the third insulator 105 changes. At the same time, the push rod 105b can pull the flat iron 106 to rotate along the hinge point between it and the static contact C1 of the first insulator 102.

[0063] Example 3

[0064] Reference Figures 1 to 4 , which is the third embodiment of the present invention, includes a driving rod 104 that penetrates the base 101 and extends to the outside thereof; the driving rod 104 includes a manual part 104a arranged at one end thereof, and an electric part 104b arranged at the other end; the electric part 104b can be connected to the output end of the motor M.

[0065] In this embodiment, the driving rod 104 adopts a rod-shaped structure, and both ends of the driving rod 104 extend beyond one end of the base 101; its manual part 104a is a rod-shaped structure that is perpendicular to the driving rod 104; and hanging points are arranged at the top positions of both ends; thereby, it is more convenient for the operator to drive the driving rod 104 to rotate in a more labor-saving manner.

[0066] Specifically, the electric part 104b is a slender rod-shaped structure protruding from a part of the base 101; the electric part 104b is used to connect with the output end of the motor; after the motor is connected to the electric part 104b through a coupling, it can be driven by the motor, thereby driving the driving rod 104 to rotate.

[0067] Furthermore, a limit plate 108 is disposed outside the driving rod 104 , and the limit plate 108 moves synchronously with the driving rod 104 ; the limit plate 108 is in conflict with the surface of the base 101 ; and a limit column 109 adapted to the limit plate 108 is disposed on the surface of the base 101 .

[0068] It should be noted that a limit plate 108 is arranged on the outer side of the driving rod 104, and the position of the limit plate 108 is close to the surface of the base 101; the limit plate 108 can rotate synchronously with the driving rod 104; and a limit column 109 is arranged at a position consistent with the movement trajectory of the limit plate 108, and the limit column 109 protrudes from the surface of the base 101; during the rotation of the limit plate 108, the limit column 109 can cause a certain interference to the movement of the limit plate 108.

[0069] Specifically, the setting of the limiting column 109 can ensure that after the flat iron 106 moves to the appropriate position, the driving rod 104 is limited and remains stationary; thereby effectively preventing the flat iron 106 from moving beyond the range and causing damage to the equipment.

[0070] Furthermore, the number of the connecting sleeves 107 corresponds to the number of the third insulators 105; the connecting sleeves 107 and the driving rod 104 are interference fit; and the fixing plate 107a and the hinge seat 105a are hinged and rotated.

[0071] In this embodiment, the driving rod 104 and the connecting sleeve 107 can be an interference fit, and the driving rod 104 can drive the connecting sleeve 107 to rotate during the rotation process; at the same time, the fixed plate 107a and the hinge seat 105a are hinged, and the rotation of the connecting sleeve 107 can drive the third insulator 105 to flip along the moving trajectory. When the third insulator 105 flips, it can drive the flat iron 106 to rotate along the hinge between it and the static contact C1 of the first insulator 102.

[0072] Furthermore, there are multiple groups of first insulators 102 , which are evenly distributed on the surface of the base 101 ; a copper busbar 110 is connected to the outer side of the static contact C1 of the first insulator 102 ; and the copper busbar 110 connects the multiple groups of first insulators 102 in series.

[0073] In this embodiment, the first insulator 102 and the second insulator 103 may also be porcelain insulators, which have high mechanical strength, high temperature resistance, corrosion resistance, and long service life; and are widely used in high-voltage transmission lines and substations.

[0074] Furthermore, a ground wire 111 is connected to the end of the copper busbar 110 ; the copper busbar 110 and the base 101 are connected via the ground wire 111 ; and the bottom of the ground wire 111 is grounded.

[0075] It should be noted that multiple groups of lines are connected in series through the copper bus 110. When a short circuit occurs, the three-phase line can be controlled to close to ensure that the three-phase circuit can be grounded at the same time, effectively avoiding the situation where the circuit is not grounded.

[0076] Furthermore, an elastic member 112 is disposed on one side of the driving rod 104 ; the driving rod 104 and the base 101 are connected via the elastic member 112 .

[0077] It should be noted that the elastic member 112 can provide the necessary contact pressure to ensure good electrical contact between the moving contact and the stationary contact; this can reduce contact resistance, improve conductivity, and prevent heating and arcing caused by poor contact.

[0078] Example 4

[0079] Reference Figure 1 to Figure 4 , which is the fourth embodiment of the present invention, and this embodiment further provides an intelligent remote control system, including a control unit, including a battery intelligent charging module, a DC motor intelligent module and an intelligent controller Bluetooth control module; the DC motor intelligent module can control the start and stop of the motor; the battery intelligent charging module is connected to a battery, and the battery can provide power for the device; the DC motor intelligent module and the intelligent controller Bluetooth control module communicate through the mobile phone Bluetooth.

[0081] Furthermore, the DC motor intelligent module is connected to the DC motor, and the DC motor intelligent module can control the start and stop of the motor.

[0082] Specifically, in order to further meet the requirement of remotely controlling the start and stop of the DC motor, an intelligent controller Bluetooth control module that interacts with the DC motor intelligent module is also provided; the intelligent controller Bluetooth control module can establish a connection with the mobile phone Bluetooth, thereby realizing the remote control of the start and stop of the DC motor by the mobile phone.

[0083] It should be noted that the knife switch is installed on the cross arm behind the 10KV drop-out fuse of the transformer substation and fixed. From the outlet of the lower contact of the 10KV drop-out fuse, a JKLY-10KV / 95 high-voltage insulating wire sheath and a 15KV cold shrink insulating tube are used to lead from the middle of the two cross arms to the three grounding knife switch static contacts, and the grounding end is connected to the grounding wire led from the transformer grounding device; the 220V AC power in the substation area is used to intelligently charge the battery, the combined DC motor intelligent control module, and the Bluetooth control module, and the Bluetooth remote control controls the operation of the DC motor.

[0084] Manual operation: The driving rod is connected to the DC forward and reverse motor, and the insulated pull-switch rod can be used to pull and operate the grounding knife switch transmission mechanism to realize manual closing and opening.
