Description

Technical Field

[0001] The present invention relates to the technical field of live-line working in power distribution, and in particular to a live-line working short-circuiting device and a method of using the same. Background Art

[0002] The requirements for safe operation and power supply reliability of power systems are becoming increasingly higher. Non-stop operation is becoming a trend. In load operation, insulated drain wires are often used to build small bypass systems to isolate the equipment to be repaired and achieve non-stop maintenance.

[0003] There are two existing bypass methods. One is to build a bypass system by combining bypass flexible cables with bypass load switches. However, this method requires more manpower to lay cables, and the bypass equipment is heavy, time-consuming and labor-intensive. The other is to build a small bypass system through insulated drainage lines to directly short-circuit the equipment to be replaced (switches or switches, etc.). However, this method is more complicated, and the insulated drainage lines are difficult to fix, place, and spread. The operation process is not stable and safe enough.

[0004] As the power grid continues to expand, the number of bypass operations continues to increase. How to reduce the time and labor consumption of bypass operations while ensuring the safety and reliability of the non-stop operation process has become an urgent problem to be solved. Summary of the invention

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A live working short-circuit device comprises a mounting base and a first cable storage assembly, a second cable storage assembly, a first switch and a second switch arranged on the mounting base;

[0008] The first switch is conductively connected to the second switch, the first cable storage assembly is provided with a first closed contact corresponding to the first switch, and the second cable storage assembly is provided with a second closed contact corresponding to the second switch;

[0009] A first bypass wiring is provided in the first cable storage assembly, one end of which is electrically connected to the first closed contact, and a second bypass wiring is provided in the second cable storage assembly, one end of which is electrically connected to the second closed contact.

[0010] In order to solve the above technical problems, another technical solution adopted by the present invention is:

[0011] A method for using a live working short-circuit device, applied to the above-mentioned live working short-circuit device, comprises the following steps:

[0012] S1. Install the entire short-circuit device to the target bypass operation position through the mounting base;

[0013] S2, keeping the first switch and the second switch in an off state, and connecting the first bypass wiring and the second bypass wiring to the corresponding main wiring to be bypassed respectively;

[0014] S3. Use the operating insulating rod to close the first switch and the second switch to complete the bypass.

[0015] The beneficial effects of the present invention are: providing a live working short-circuiting device, which is directly installed on the target bypass working position through an installation base, and firstly connecting the first bypass wiring and the second bypass wiring while keeping the first switch and the second switch disconnected, and then closing the first switch and the second switch by operating the insulating rod to complete the bypass. Since the bypass wiring is stored in the storage component, the whole device is more convenient to move, and the problems of difficult fixing, placement and display are avoided during the bypass process. The first switch and the second switch are relied on to ensure the safety of personnel in non-stop operation, simplify the live bypass operation process, and ensure the safety and reliability of the operation process.

[0023] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0024] Please refer to Figure 1 and Figure 2 , a live working short-circuit device, comprising a mounting base 1 and a first cable storage assembly 2, a second cable storage assembly 3, a first switch 4 and a second switch 5 arranged on the mounting base 1;

[0025] The first switch 4 is conductively connected to the second switch 5, the first cable storage assembly 2 is provided with a first closed contact 6 corresponding to the first switch 4, and the second cable storage assembly 3 is provided with a second closed contact 7 corresponding to the second switch 5;

[0026] A first bypass wiring 21 is provided in the first cable storage assembly 2, one end of which is electrically connected to the first closed contact 6, and a second bypass wiring 31 is provided in the second cable storage assembly 3, one end of which is electrically connected to the second closed contact 7.

[0027] From the above description, it can be seen that the beneficial effects of the present invention are: it is directly installed on the target bypass operation position through the installation base 1, and the first bypass wiring 21 and the second bypass wiring 31 are first connected while keeping the first switch 4 and the second switch 5 disconnected, and then the first switch 4 and the second switch 5 are closed by operating the insulating rod to complete the bypass. Since the bypass wiring is stored in the storage component, the whole device is more convenient to move, and the problems of difficult fixing, placement, and display are avoided during the bypass process. The first switch 4 and the second switch 5 are relied on to ensure the safety of personnel in non-stop operation, simplify the live bypass operation process, and ensure the safety and reliability of the operation process.

[0028] Further, the first cable storage assembly 2 includes a first main guide rod 22;

[0029] The first closing contact 6 is disposed on the mounting base 1, one end of the first main rod 22 is connected to the first closing contact 6, and the first bypass wiring 21 is wound around the first main rod 22;

[0030] The second cable storage assembly 3 includes a second main guide rod 32;

[0031] The second closing contact 7 is disposed on the mounting base 1 , one end of the second main rod 32 is connected to the second closing contact 7 , and the second bypass wiring 31 is wound around the second main rod 32 .

[0032] From the above description, it can be seen that by setting the main rod, a winding basis is provided for the bypass wiring, which improves the convenience of cable storage and also makes it easier to unfold and use the cables.

[0033] Further, the first cable storage assembly 2 includes a first telescopic sleeve 23 and a first connector 24;

[0034] The first telescopic sleeve 23 is sleeved on the first main rod 22, one end of the first telescopic sleeve 23 is connected to the first closed contact 6, the first joint 24 is arranged on the other end of the first telescopic sleeve 23, and the end of the first bypass wiring 21 located in the first telescopic sleeve 23 away from the first closed contact 6 is conductively connected to the first joint 24.

[0035] From the above description, it can be seen that the first telescopic sleeve 23 can not only protect the bypass wiring, but also cooperate with the first joint 24. By stretching a telescopic sleeve, the first bypass wiring 21 can be lengthened to facilitate the flexible connection of the first joint 24 with the main wire to be bypassed, and avoid problems such as difficulty in fixing the bypass wiring, thereby reducing the difficulty of operation.

[0036] Further, the second cable storage assembly 3 includes a second telescopic sleeve 33 and a second connector 34;

[0037] The second telescopic sleeve 33 is sleeved on the second main rod 32, one end of the second telescopic sleeve 33 is connected to the second closed contact 7, the second connector 34 is arranged on the other end of the second telescopic sleeve 33, and the end of the second bypass wiring 31 located in the second telescopic sleeve 33 away from the second closed contact 7 is conductively connected to the second connector 34.

[0038] From the above description, it can be seen that the second telescopic sleeve 33 can not only protect the bypass wiring, but also cooperate with the second joint 34. By stretching the second telescopic sleeve, the second bypass wiring 31 can be lengthened to facilitate the flexible connection of the second joint 34 with the main wire to be bypassed, and avoid the problem of difficulty in fixing the bypass wiring, thereby reducing the difficulty of operation.

[0039] Furthermore, the first cable storage assembly 2 further includes an insulating support column 8 and an inclined support rod 9;

[0040] The insulating support column 8 is arranged on the mounting base 1 , the first closed contact 6 is arranged on the insulating support column 8 , one end of the inclined support rod 9 is connected to the insulating support column 8 , and the other end of the inclined support rod 9 is detachably connected to the first telescopic sleeve 23 .

[0041] From the above description, it can be seen that the insulating support column 8 has high mechanical strength and insulation performance, which ensures that the connection at the first closed contact 6 is not disturbed and improves the conductive stability. At the same time, the inclined support rod 9 is provided to support the extended first telescopic sleeve 23 and enhance the stability of the device.

[0042] Furthermore, a telescopic limiting member 10 is provided on the first telescopic sleeve 23 .

[0043] It can be seen from the above description that by providing the telescopic limiter 10 , the stretched length can be maintained after the first telescopic sleeve 23 is stretched to a predetermined length.

[0044] Furthermore, the mounting base 1 is provided with a first receiving chute 11 and a second receiving chute 12;

[0045] The first cable storage assembly 2 is slidably disposed on the first storage slide groove 11, and the second cable storage assembly 3 is slidably disposed on the second storage slide groove 12;

[0046] In the sliding direction of the first cable storage assembly 2, the length of the first storage slot 11 is greater than or equal to the length of the first cable storage assembly 2 in its own sliding direction;

[0047] In the sliding direction of the second cable storage assembly 3 , the length of the second storage slot 12 is greater than or equal to the length of the second cable storage assembly 3 in its own sliding direction.

[0048] From the above description, it can be seen that by providing the first storage slot 11 and the second storage slot 12, the first cable storage assembly 2 and the second cable storage assembly 3 can be completely stored above the mounting base 1, thereby reducing the space occupied by the device in the stored state and facilitating carrying and use.

[0049] Furthermore, the first receiving chute 11 has a first branch chute 13, and the second receiving chute 12 has a second branch chute 14;

[0050] When the first cable storage assembly 2 is located in the first branch slot 13 and the second cable storage assembly 3 is located on the second branch slot 14, the first cable storage assembly 2, the first switch 4, the second switch 5 and the second cable storage assembly 3 are successively distributed on the mounting base 1 along the same straight line direction.

[0051] From the above description, it can be seen that on the basis of providing overall storage for the device, a branch chute is provided. After the cable storage assembly moves on the branch chute, the state of the device after unfolding can be flexibly adjusted to meet actual bypass operation needs.

[0052] Please refer to Figure 3A method for using a live working short-circuit device, which is applied to the above-mentioned live working short-circuit device, comprises the following steps:

[0053] S1. Install the entire short-circuit device to the target bypass operation position by installing the base 1;

[0054] S2, keeping the first switch 4 and the second switch 5 in the off state, and connecting the first bypass wiring 21 and the second bypass wiring 31 to the corresponding main wiring to be bypassed respectively;

[0055] S3. Use the operating insulating rod to close the first switch 4 and the second switch 5 to complete the bypass.

[0056] From the above description, it can be seen that the beneficial effects of the present invention are: it is directly installed on the target bypass operation position through the installation base 1, and the first bypass wiring 21 and the second bypass wiring 31 are first connected while keeping the first switch 4 and the second switch 5 disconnected, and then the first switch 4 and the second switch 5 are closed by operating the insulating rod to complete the bypass. Since the bypass wiring is stored in the storage component, the whole device is more convenient to move, and the problems of difficult fixing, placement, and display are avoided during the bypass process. The first switch 4 and the second switch 5 are relied on to ensure the safety of personnel in non-stop operation, simplify the live bypass operation process, and ensure the safety and reliability of the operation process.

[0057] Furthermore, the step S1 further includes:

[0058] Move the first cable storage assembly 2 to the first branch chute 13 and the second cable storage assembly 3 to the second branch chute 14 to complete the deployment of the device;

[0059] After step S3, the following steps are also included:

[0060] S4. When the bypass needs to be removed, retract the first bypass wiring 21 and the second bypass wiring 31, move the first cable storage assembly 2 to the first storage chute 11, and move the second cable storage assembly 3 to the second storage chute 12 to complete the device storage.

[0061] From the above description, it can be seen that by providing the first storage slot 11 and the second storage slot 12, the first cable storage assembly 2 and the second cable storage assembly 3 can be completely stored above the mounting base 1, thereby reducing the space occupied by the device in the stored state and facilitating carrying and use.
