Description

Technical Field

[0001] The utility model relates to the technical field of busbar components, in particular to a switch plug-in cabinet assembly. Background Art

[0002] In the power system, busbar refers to a product or equipment made of high-conductivity copper bars for transmitting electrical energy. It has the function of collecting and distributing electricity. It is the main conductor used to transmit electrical energy in power stations or substations. Through it, the electrical energy output by generators, transformers or rectifier equipment is transmitted to various users or other substations. Busbars are divided into hard busbars and soft busbars according to their structure. Hard busbars are further divided into rectangular busbars, tubular busbars, trough busbars, diamond busbars and other types, and are widely used.

[0003] The existing split-type busbar structure for parallel connection of switches has the following disadvantages when in use: At present, split-type busbar structure is used for parallel connection of switches both internationally and domestically, which is affected by the position error of ring network cabinet and causes certain damage to the normal operation of offshore wind power. Due to the limitation of offshore wind power transportation conditions, maintenance or overhaul is very inconvenient. In addition, the split busbar has many insulation matching interfaces, difficult exhaust, and silicone grease easily enters the conductor surface. Therefore, there is an urgent need for a cabinet assembly product with few insulation matching interfaces and quick installation. To this end, we propose a switch plug-in cabinet assembly device. Utility Model Content

[0004] The main purpose of the utility model is to provide a switch plug-in cabinet assembly device, which can realize the rapid installation of cabinet assembly products by adopting a plug-in structure and cooperating with a clamping mechanism, and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A switch plug-in cabinet assembly includes a plug-in cabinet assembly, an insertable insulating protective sleeve and a clamping mechanism. A slot is provided inside the insertable insulating protective sleeve and a connecting end of the plug-in cabinet assembly is inserted into the slot. A clamping mechanism is installed between the insertable insulating protective sleeve and the plug-in cabinet assembly. The clamping mechanism includes a base, a pressure plate, a screw and a nut. A pressure plate is clamped on the top of the plug-in cabinet assembly and screws are installed vertically between the two sides of the pressure plate and the base. The bottom of the screw is inserted into the base and a nut is threadedly connected to the outer periphery of the screw.

[0007] Furthermore, the plug-in cabinet is composed of a conductor bus, a busbar equalizing conductive layer, a high-voltage insulating layer and an outer shielding conductive layer. A conductor bus is installed inside the plug-in cabinet, and a busbar equalizing conductive layer is integrally formed on the outer periphery of the conductor bus. A high-voltage insulating layer is arranged on the outer periphery of the busbar equalizing conductive layer, and the outer periphery of the high-voltage insulating layer is covered with an outer shielding conductive layer. The busbar equalizing conductive layer and the conductor bus are an integral whole without a connection interface. The internal body of the switch-integrated plug-in cabinet is an integral structure without any connection interface, which makes the electric field uniform, reduces the insulation matching interface, reduces the influence of the position error of the ring network cabinet, and improves the reliability of operation.

[0008] Furthermore, a bottom plate is installed on the top of the base and the end of the bottom plate is attached to the surface of the insertable insulating protective cover, and the screw rod passes through the bottom plate; the bottom plate plays a role of connection and limiting.

[0009] Furthermore, the nuts are fitted to the surface of the pressing plate and are respectively located at the upper and lower sides of the pressing plate; the pressing plate and the screw rod are connected together by the nuts.

[0010] Furthermore, bolts are installed in the horizontal direction inside the base and the insertable insulating protective sleeve; the base and the insertable insulating protective sleeve are fixed together by the bolts.

[0011] Compared with the prior art, the utility model has the following beneficial effects: an insertable insulating protective cover structure with a slot is adopted, and the plug-in cabinet splicer is directly inserted into the top of the insertable insulating protective cover, and a pressure plate is installed on the top after it is inserted into place, and the screw and the base are connected together, which is convenient for installation and maintenance. When the temperature rise such as excessive installation or poor plugging causes the pressure in the inner cavity of the cabinet splicer to increase, the cabinet splicer can be automatically withdrawn, and the pressure is released without damaging the switch cabinet, reducing equipment damage, effectively protecting the cabinet, improving the safety of the system, and being easier to produce and install, reducing the requirements for equipment; the busbar equalizing conductive layer and the conductor busbar are an integral whole, without any connection interface, and the internal body of the switch integral plug-in cabinet splicer is an integral structure without any connection interface, so that the electric field is uniform, the insulation matching interface is reduced, the influence of the position error of the ring network cabinet is reduced, and the reliability of operation is improved.
