[0002] In the field of power facility operation and maintenance technology, there is a frequent need for live work in narrow spaces such as low-voltage outdoor power distribution reactive compensation integrated cabinets, meter boxes and switch cabinets. Limited by the compact internal space of these devices, the lack of suitable insulation shielding and isolation tools during wire removal and wiring operations results in low efficiency and high labor intensity, and is prone to serious safety accidents such as electric shock, short circuit, grounding and explosion. These technical defects not only threaten the safety and reliability of power supply, but also have a negative impact on the economic and social benefits of power supply companies.

[0003] The insulating tools currently used have many limitations and fail to effectively meet the needs of actual operations. For example, the size and shape of standard insulating tools may not be fully compatible with the internal structure of the low-voltage cabinet, resulting in the inability to completely cover the necessary areas, leaving safety hazards. At the same time, the material selection of existing tools is relatively single, and it is difficult to have the required flexibility and hardness at the same time to adapt to complex working environments. In the actual operation process, due to the incompatibility of tools, workers have to spend extra time to adjust and try, which not only increases the operation time and labor intensity, but also easily causes serious safety accidents such as electric shock, short circuit, grounding, and explosion due to operational errors. These accidents not only threaten the life safety of workers, but may also cause damage to power equipment, interrupt normal power supply, and cause serious impacts and losses to social production and daily life.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0030] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text is to include three parallel solutions. Taking "A and / or B as an example", it includes solution A, or solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0032] In the field of power facility operation and maintenance technology, there is a frequent need for live work in narrow spaces such as low-voltage outdoor power distribution reactive compensation integrated cabinets, meter boxes and switch cabinets. Limited by the compact internal space of these devices, the lack of suitable insulation shielding and isolation tools during wire removal and wiring operations results in low efficiency and high labor intensity, and is prone to serious safety accidents such as electric shock, short circuit, grounding and explosion. These technical defects not only threaten the safety and reliability of power supply, but also have a negative impact on the economic and social benefits of power supply companies.

[0033] The insulating tools currently used have many limitations and fail to effectively meet the needs of actual operations. For example, the size and shape of standard insulating tools may not be fully compatible with the internal structure of the low-voltage cabinet, resulting in the inability to completely cover the necessary areas, leaving safety hazards. At the same time, the material selection of existing tools is relatively single, and it is difficult to have the required flexibility and hardness at the same time to adapt to complex working environments. In the actual operation process, due to the incompatibility of tools, workers have to spend extra time to adjust and try, which not only increases the operation time and labor intensity, but also easily causes serious safety accidents such as electric shock, short circuit, grounding, and explosion due to operational errors. These accidents not only threaten the life safety of workers, but may also cause damage to power equipment, interrupt normal power supply, and cause serious impacts and losses to social production and daily life.

[0034] In order to improve the deficiencies of the above-mentioned prior art, the main purpose of the present invention is to provide an insulating shielding combination tool for low-voltage live working in distribution cabinets, aiming to improve the deficiencies of the above-mentioned prior art, improve the versatility and flexibility of the insulating shielding combination tool, increase user working efficiency, reduce labor intensity, and significantly reduce safety risks.

[0035] The following will be combined Figures 1 to 8 The coal mine underground conveying device provided in the embodiment of the present application is described in detail through specific embodiments. Figure 1 It is a schematic structural diagram of a first isolation mechanism of an embodiment of the insulation shielding assembly tool of the present invention; Figure 2 for Figure 1 A schematic diagram of the partial structure of the embodiment and the power distribution cabinet; Figure 3 A schematic diagram of the structure of a second isolation mechanism of an embodiment of the insulation shielding assembly of the present invention; Figure 4 for Figure 3 A schematic diagram of the partial structure of the embodiment and the power distribution cabinet; Figure 5 It is a schematic structural diagram of a third isolation mechanism of an embodiment of the insulation shielding assembly tool of the present invention; Figure 6 for Figure 5 A schematic diagram of the partial structure of the embodiment and the power distribution cabinet; Figure 7 A schematic diagram of the structure of a fourth isolation mechanism of an embodiment of the insulation shielding assembly of the present invention; Figure 8 for Figure 7 Schematic diagram of the partial structure of the embodiment and the power distribution cabinet.

[0036] Combined with reference Figures 1 to 8 The technical solution of the present invention proposes an insulating shielding assembly 100 for low-voltage live working of a distribution cabinet, which is used for a distribution cabinet. The distribution cabinet includes a wire end and a copper busbar. The insulating shielding assembly 100 includes a first isolation mechanism 10 and a second isolation mechanism 30. The first isolation mechanism 10 includes a first isolation body 11 and a first fixing mechanism 13. The first isolation body 11 is made of an insulating material and is formed with a first accommodating groove. The shape of the first accommodating groove corresponds to the arrangement of the wire end. The first fixing mechanism 13 is arranged at the notch of the first accommodating groove and is used to fix the first isolation body 11 and the wire end; the second isolation mechanism 30 includes a second isolation body 31 and a second fixing mechanism 33. The second isolation body 31 is made of an insulating material and is enclosed to form a second accommodating cavity 311. The second accommodating cavity 311 is used to cover the copper busbar. The second fixing mechanism 33 is arranged at the cavity mouth of the second accommodating cavity 311 and is used to fix the second isolation body 31 and the copper busbar.

[0037] It should be noted that the distribution cabinet is an electrical equipment mainly used for controlling, protecting and monitoring the power system. It usually contains multiple switchgear, measuring instruments, protection devices and control equipment, which are used to distribute electrical energy to various electrical equipment or areas. Distribution cabinets are widely used in industrial, commercial and residential buildings to ensure the reliability and safety of power supply. Common components in distribution cabinets include wire ends and copper bars, where the wire end refers to the part where the wire is connected to the distribution cabinet or other electrical equipment, usually with a metal joint of a fixed size; copper bars, also known as bus bars or bus bars, are conductive metal strips used to transmit electrical energy in distribution cabinets. During the low-voltage live operation of the distribution cabinet, in order to ensure the reasonable arrangement of the space in the distribution cabinet and the efficiency of space utilization, it is usually necessary to arrange multiple sections of wires or copper bars in a relatively dense interval. Therefore, the wire ends and / or copper bars of adjacent wires need to be insulated and shielded.

[0038] During the use of the insulation shielding assembly 100 for low-voltage live working in a power distribution cabinet proposed in the technical solution of the present invention, it is first necessary to select the first isolation mechanism 10 and the second isolation mechanism 30 in the assembly according to the number of wire ends and / or copper bars in the power distribution cabinet. Specifically, the first isolation mechanism 10 at least partially covers each wire end to isolate it from the adjacent wire ends. In the first isolation mechanism 10, the first isolation body 11 is an insulating material, which can be polyethylene, polyvinyl chloride, silicone rubber, polytetrafluoroethylene, epoxy resin, phenolic resin or composite material, etc., and this application does not make specific restrictions on this. The first accommodating groove (not shown in the figure) provided in the first isolation body 11 is used to accommodate the wire end. Specifically, the first isolation body 11 with first accommodating grooves of different shapes can be provided to adapt to wire ends of different shapes such as round, fork-shaped, needle-shaped, ring-shaped or U-shaped. In this way, the flexibility and extensiveness of the use of the first isolation mechanism 10 and the insulation shielding assembly 100 are further increased. The first fixing mechanism 13 provided at the notch of the first accommodating groove and used to fix the first isolation body 11 and the wire end can be fixed by means of snap-fitting, sleeve-fitting, plug-in or bonding, etc., and the present application does not make specific restrictions on this. On the other hand, the second accommodating cavity 311 formed in the second isolation mechanism 30 accommodates at least part of the copper bar so that it has a certain interval with the adjacent copper bar or end. In the second isolation mechanism 30, the second isolation body 31 is an insulating material, which can be polyethylene, polyvinyl chloride, silicone rubber, polytetrafluoroethylene, epoxy resin, phenolic resin or composite material, etc., and the present application does not make specific restrictions on this. The second fixing mechanism 33 provided at the cavity mouth of the second accommodating cavity 311 and used to fix the second isolation body 31 and the copper bar can be fixed by means of snap-fitting, sleeve-fitting, plug-in or bonding, etc., and the present application does not make specific restrictions on this.

[0039] In some embodiments of the present invention, in combination with reference Figure 1 and Figure 2 The first fixing mechanism 13 includes at least two first fixing plates 131 and a first fixing buckle 133. The first fixing plate 131 is integrally formed with the first isolation body 11, and at least two first fixing plates 131 are spaced apart along the notch of the first accommodating groove; the first fixing buckle 133 is penetrated through at least two first fixing plates 131, and is at least partially clamped and fixed to a wall surface of one first fixing plate 131 facing away from the other first fixing plate 131.

[0040] It can be understood that at least two first fixing plates 131 are arranged at intervals along the notch of the first receiving groove, so that the first fixing buckle 133 penetrating the two first fixing plates 131 can apply pressure to the wall surface of one first fixing plate 131 away from the other first fixing plate 131 so that the two first fixing plates 131 have a tendency to approach each other. And because the first fixing plates 131 and the first isolation body 11 are integrally formed, under the influence of the first fixing buckle 133, the two first fixing plates 131 cause the structure at the notch of the first receiving groove to deform, thereby causing the first isolation body 11 to clamp and fix the wire end at the notch, so that the wire end has a relatively fixed positional relationship with the first isolation body 11 and the first isolation mechanism 10, and the first isolation mechanism 10 is fixed to the wire end without adding additional components, and the first isolation mechanism 10 is fixed to the wire end without affecting the stability of the first isolation mechanism 10, and the use flexibility of the first isolation mechanism 10 and the insulation shielding assembly 100 is further increased.

[0041] In the technical solution of an embodiment of the present invention, the first isolation body 11 is made of a flexible material, and the first fixing plate 131 and the first isolation body 11 are integrally formed.

[0042] It is understandable that the flexible material of the first isolation body 11 can be polyester, polyimide, banana, silicone rubber, polytetrafluoroethylene, polypropylene or ethylene copolymer, etc., and the present application does not make specific limitations on this. The integral molding arrangement of the first fixed plate 131 and the first isolation body 11 further simplifies the production process, reduces production time and cost, and at the same time improves the accuracy and repeatability of component production. Furthermore, the first isolation body 11 and the first fixed plate 131 made of flexible material can be molded into different fixed shapes or structures according to different design requirements, such as wire ends of different lengths and shapes, to provide greater design freedom and reduce material waste that may be generated in the traditional manufacturing process. On the other hand, the one-piece molded structure has a tighter internal physical structure, thereby better isolating the interference of the electromagnetic field and obtaining better electromagnetic compatibility.

[0043] As a feasible implementation mode, the outer peripheral surface of the first isolation body 11 on the side away from the slot of the first accommodating groove is an arc surface. In this way, without affecting the insulation shielding effect of the first isolation body 11, it has a smoother outer contour, reduces friction with another adjacent first isolation body 11, and also reduces the possibility of scratches on installers by regular edges and corners during the installation process, thereby improving the safety of the first isolation mechanism 10 and the insulation shielding combination tool 100.

[0044] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the second isolation body 31 is made of flexible material, and the second fixing mechanism 33 includes a second fixing edge 331 and a second fixing rope 333. The second fixing edge 331 is arranged around the outer peripheral surface of the second isolation body 31 near the cavity opening, and is enclosed with the second isolation body 31 to form a second fixing channel; the second fixing rope 333 is passed through the second fixing channel, and has two ends respectively exposed outside the second fixing channel.

[0045] It is understandable that the second isolation body 31, which is set to a flexible material, can also be polyester, polyimide, banana, silicone rubber, polytetrafluoroethylene, polypropylene or ethylene copolymer, etc., and this application does not make specific restrictions on this. The second fixed curling edge 331, which is arranged on the outer peripheral surface of the second isolation body 31 near the cavity opening, is used to form a second fixed channel (not shown in the figure). The space formed in the channel constrains the activity area of ​​the second fixed rope 333. In this way, the two ends of the second fixed rope 333 exposed outside the second fixed channel can be knotted, wound, etc. to affect the shape of the second isolation body 31, tighten the cavity opening size of the second accommodating cavity 311 formed by the second isolation body 31, and then realize the fixation of the second isolation mechanism 30 and the copper busbar without adding additional components, and further increase the flexibility of use of the second isolation mechanism 30 and the insulating shielding assembly 100 without affecting the stability of the second isolation mechanism 30.

[0046] In the technical solution of an embodiment of the present invention, the second fixed curled edge 331 and the second isolation body 31 are integrally formed.

[0047] It can be understood that the integral molding of the second fixed curl 331 and the second isolation body 31 further simplifies the production process, reduces production time and cost, and at the same time improves the accuracy and repeatability of component production. Furthermore, the second isolation body 31 and the second fixed curl 331 made of flexible material can be molded into different fixed shapes or structures according to different design requirements, such as copper bars of different lengths and shapes, to provide greater design freedom and reduce material waste that may be generated in the traditional manufacturing process. On the other hand, the one-piece molding structure has a tighter internal physical structure, thereby better isolating the interference of the electromagnetic field and obtaining better electromagnetic compatibility, further increasing the flexibility and safety of the use of the second isolation mechanism 30 and the insulating shielding combination device 100.

[0048] In some embodiments of the present invention, in combination with reference Figure 5 and Figure 6 The copper busbar has edges with a cross-section that is approximately right-angled. The insulating shielding assembly 100 also includes a third isolation mechanism 50, which includes a third isolation body 51 and a third fixing mechanism 53. The third isolation body 51 is made of insulating material and has a third accommodating groove 511 with a right-angle profile corresponding to the copper busbar. The third fixing mechanism 53 is arranged at the notch of the third accommodating groove 511 and is used to fix the third isolation body 51 and the copper busbar.

[0049] It should be noted that, as a common conductive path in a conductive cabinet, the copper busbar has a common cross-sectional shape of a rectangle or a chamfered (rounded) rectangle to reduce the risk of tip discharge. Regardless of whether it is a rectangle or a chamfered (rounded) rectangle, it has edges arranged at right angles. In this way, a third isolation mechanism 50 having a third accommodating groove 511 of a corresponding shape is arranged corresponding to the right-angled edge. It is not necessary to completely cover each of the spaced copper busbars. Only the edges arranged at right angles where each copper busbar may contact the adjacent copper busbars need to be covered to achieve the insulation shielding effect of the copper busbars, thereby further increasing the economy and flexibility of use of the third isolation mechanism 50 and the insulating shielding combination tool 100.

[0050] It is understandable that the third isolation body 51 is made of insulating material, which may be polyethylene, polyvinyl chloride, silicone rubber, polytetrafluoroethylene, epoxy resin, phenolic resin or a composite material, etc. This application does not make any specific limitation on this.

[0051] In the technical solution of an embodiment of the present invention, the third isolation body 51 is made of flexible material, and the third fixing mechanism 53 is at least partially disposed through the opposite walls on both sides of the third accommodating groove 511 and is used to change the distance between the opposite walls on both sides.

[0052] It is understandable that the flexible material of the third isolation body 51 can be polyester, polyimide, banana, silicone rubber, polytetrafluoroethylene, polypropylene or ethylene copolymer, etc., and this application does not make specific restrictions on this. In order to facilitate the fixing process of the third isolation body 51 and the copper busbar with edges arranged at right angles, the notch of the third accommodating groove 511 provided by the third isolation body 51 can be set to be formed by enclosing two adjacent non-parallel end faces. At this time, the third fixing mechanism 53 is passed through the two side walls of the notch of the third accommodating groove 511, and the third isolation body 51 and the copper busbar can be fixed by changing the relative distance between the walls through the third fixing mechanism 53. Specifically, the third fixing mechanism 53 and the third isolation body 51 that are passed through the two side walls of the third accommodating groove 511 can be screwed, clamped or plugged, etc., and this application does not make specific restrictions on this.

[0053] In some embodiments of the present invention, Figure 7 and Figure 8 As shown, the insulating shielding assembly 100 also includes a fourth isolation mechanism 70, which includes a fourth isolation body 71 and a fourth fixing mechanism 73. The fourth isolation body 71 is a planar flexible material with multiple edges. The fourth fixing mechanism 73 is arranged at the edge of the fourth isolation body 71 and extends toward the center of the plane of the fourth isolation body 71 to fix the fourth isolation body 71 and the copper busbar when the fourth isolation body 71 is folded to cover the copper busbar.

[0054] It is understandable that in some electrical cabinets, the area of ​​the circuit or electronic components that need to be insulated and shielded is relatively large. At this time, the first, second or third isolation mechanism 50 cannot simply insulate and shield them, and the fourth isolation mechanism 70 is required to perform insulation and shielding. Therefore, the fourth isolation body 71 included in the fourth isolation mechanism 70 for insulation shielding is a planar structure of a flexible material with multiple edges. In this way, the circuit or electronic components with a large area and volume can be insulated and shielded by manual winding and wrapping. At this time, in order to prevent the wound and wrapped fourth isolation body 71 from restoring its original shape due to elastic deformation, affecting the insulation shielding effect, a fourth fixing mechanism 73 is provided on the fourth isolation body 71 to fix the fourth isolation body 71 and the copper busbar. Specifically, the fourth fixing mechanism 73 is arranged at the edge of the fourth isolation body 71 and extends toward the center of the plane of the fourth isolation body 71. In this way, while not affecting the insulation shielding effect of the fourth isolation body 71, the fourth fixing structure has a relatively larger stress application area, thereby increasing the fixing stability performance of the fourth fixing structure.

[0055] In the technical solution of one embodiment of the present invention, the fourth fixing mechanism 73 includes at least two bonding units 731, and the at least two bonding units 731 are correspondingly arranged on two opposite edges of the fourth isolation body 71 so as to be bonded and connected to each other when the fourth isolation body 71 and the copper busbar are fixed.

[0056] It can be understood that the provision of the adhesive unit 731 to fix the relative edges of the fourth isolation body 71 has better flexibility and adaptability than other fixing methods such as snap-on, sleeve or plug-in, and can adapt to multiple uneven surfaces, providing a better fitting effect, and is suitable for surfaces of objects of various shapes. It does not require other tools to assist in the installation process, can be easily pasted and disassembled, and can simplify or replace steps such as riveting, welding, surface reprocessing and cleaning, thereby reducing production costs while further increasing the flexibility of use of the fourth isolation body 71 and the insulating shielding combination device 100.

[0057] In the technical solution of an embodiment of the present invention, in combination with reference Figure 7 and Figure 8 Among the at least two adhesive units 731, one adhesive unit 731 is provided with an adhesive handle 733 extending from the side of the fourth isolation body 71, so that when the fourth isolation body 71 is fixed to the copper busbar, it is wrapped around the outer circumference of the fourth isolation body 71 and adhesively connected to the fourth isolation body 71.

[0058] It should be noted that a bonding handle 733 is extended from the bonding unit 731 away from the fourth isolation body 71, so that in the process of fixing the fourth isolation body 71, the fourth fixing mechanism 73 can further increase the contact area between the operator's hand and the bonding unit 731 and / or the fourth fixing mechanism 73 during the operation through the bonding handle 733. This further provides positioning for the operator's insulation shielding operation process, thereby increasing the flexibility of use of the fourth isolation body 71 and the insulation shielding assembly 100.

[0059] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
