Description

Technical Field

[0001] The present invention relates to the technical field of low-voltage power distribution equipment, and more specifically, to a universal installation combination module for low-voltage complete sets of equipment. Background Art

[0002] The power supply system includes distribution areas with different functions. The low-voltage cabinets in the low-voltage intelligent substation are mainly distributed at the boundary points of the medium and low voltage distribution networks. The function of the low-voltage cabinet in the power grid is to distribute the load and maintain the continuous and stable operation of the power grid.

[0003] In the implementation and application of low-voltage cabinets, when it is necessary to carry out inspection, maintenance and replacement operations on the low-voltage cabinets, there are problems such as long construction operations and slow perception and response, which leads to many user complaints. This is one of the more difficult problems to deal with in distribution network infrastructure projects.

[0004] The operation of inspecting and maintaining low-voltage cabinets includes the disassembly, assembly and replacement of low-voltage complete switchgear. However, due to the complicated models and types of plug-in low-voltage complete switchgear of different brands in the low-voltage cabinets of the current medium and low voltage distribution networks, and the non-uniform structural dimensions, when replacing the low-voltage complete switchgear, it is necessary to replace the plug-in base together. The on-site maintenance and replacement operations are complicated, and the power needs to be turned off for replacement. The power outage operation is time-consuming, resulting in a high user complaint rate. In addition, there are many types of replacement spare parts that need to be prepared at the back end, which puts huge pressure on the power plant's storage.

[0005] In order to solve the problem of the existing low-voltage cabinets being difficult to disassemble and replace low-voltage complete switchgear, each manufacturer develops a base based on the appearance of the low-voltage complete switchgear they have developed, and provides a detachable plastic shell plug-in base. However, the plastic shell plug-in bases currently on the market are too simple, and the connection combination structures of each manufacturer are different, making it impossible to achieve multi-brand universality. Some manufacturers have developed low-voltage complete switchgear adapters similar to plug-in bases. If the length or height of the low-voltage complete switchgear changes, universal replacement cannot be achieved.

[0006] In view of this, in order to solve the problems that the existing low-voltage complete switchgear cannot be replaced under power, the replacement versatility is poor, and the replacement operation is cumbersome, it is urgently necessary to develop a universal low-voltage complete switchgear structure that can achieve live replacement and can be universally combined with molded case low-voltage complete switchgear of different brands. Summary of the invention

[0007] The purpose of the present invention is to provide a universal installation combination module for low-voltage complete equipment, so as to solve the problems existing in the practical application of the above-mentioned existing low-voltage switchgear. By making innovative improvements on the mechanical combination structure, it is possible to achieve universal adaptability and adjustment combination with low-voltage complete switchgear of different specifications and models, thereby improving the resource utilization rate of various spare parts of users' low-voltage complete switchgear. By using modular installation and replacement, the operation is made more convenient, thus achieving the purpose of strong combination versatility.

After all the single-phase connecting components 2 are completed and combined with the feed-out component 1, the installation of the universal installation combination module for low-voltage complete equipment is completed.

[0059] When the hexagonal wrench is inserted into the insulating connector 25 to screw and rotate the connecting bolt 21, the bolt head 211 of the hexagonal wrench connecting bolt 21 is insulated and isolated by the insulating plug 26, so as to better protect the personal safety of the operator and effectively avoid the occurrence of accidents.

[0060] When the low-voltage cabinet is put into use, it can be directly connected to the equipment through the feed-out connection end of the feed-out component 1 to complete the system access of the universal installation combination module of the low-voltage complete set of equipment.

[0061] Among them, the connection shell of the single-phase connection component 2, the feed-out shell of the feed-out component 1 and the single-phase isolation fixing part 24 can be made of the material: PA66+GF30+V0, which can improve the collision protection performance, insulation performance, high temperature resistance, etc. of the universal installation combination module of the low-voltage complete equipment. It is integrally injection molded and can meet the safe current use requirements of the low-voltage complete switchgear.

[0062] Among them, the rigid connection part 221 of the copper busbar 22 is respectively connected to the connecting bolt 21 and the locking bolt of the single-phase connection port of the low-voltage complete switch equipment 4, and the flexible connection part 222 of the copper busbar 22 can be bent and shaped accordingly according to the connection height of the single-phase connection ports between phases and the combined depth between poles of different low-voltage complete switch equipment 4, so as to realize the connection combination with low-voltage complete switch equipment 4 of different models and specifications, and has better adaptability and versatility.

[0063] When the universal installation combination module of low-voltage complete equipment is working, the heat of the transfer copper bus 11 and the connecting copper bus 22 can be fully diffused through the heat dissipation holes 7, thereby improving the heat dissipation performance of the single-phase connection component 2 and the feed-out component 1, extending the service life of the universal installation combination module of low-voltage complete equipment, and ensuring that the universal installation combination module of low-voltage complete equipment can continue to work normally.

[0064] Furthermore, the insulating pressing structure 6 includes an insulating gasket 61 and an insulating elastic gasket 62. The insulating gasket 61 fits with the connecting copper bus 22 to provide insulation protection. The insulating elastic gasket 62 is arranged between the insulating gasket 61 and the connecting bolt 21 to prevent the connecting bolt 21 from loosening.

[0067] After the replacement is completed, the low-voltage switchgear 4 and the single-phase connection component 2 of the disassembled low-voltage switchgear combination connection module are subjected to corresponding inspection and maintenance operations. After the inspection and maintenance are completed, they can be used as spare replacement parts, which greatly improves the operating efficiency.

[0068] Furthermore, when it is necessary to remove the feed-out component 1, it is only necessary to disconnect the connection of the feed-out connection end of the feed-out component 1 after removing the module combination base plate 3, and then uncouple the feed-out component 1 from the feed-out component combination hole 53, and then the feed-out component 1 can be taken out from the feed-out component installation opening 51 for replacement. After completing the replacement installation of the feed-out component 1, reinstall the module combination base plate 3 and combine the copper sleeve 23 of the single-phase connection component 2 with the feed-out component 1 to restore the operating state.
