Description

Technical Field

[0001] The utility model relates to a high-voltage cabinet with a modular design. Background Art

[0002] As the name suggests, a high-voltage cabinet is a device that connects high-voltage cables. The voltage of a high-voltage cabinet is generally higher. When in use, a transformer is needed to transform and reduce the voltage, and then transfer it to a low-voltage cabinet. The low-voltage cabinet is then distributed to the subordinate distribution boxes. The role of the high-voltage cabinet in the power industry is self-evident. The quality of the high-voltage cabinet will directly affect its safety of use.

[0003] With the rapid development of China's economy and the continuous innovation of power grid technology, high-voltage switchgear is increasingly widely used in the market. However, the existing high-voltage switchgear has the following disadvantages:

[0004] 1. The modular high-voltage cabinet in the prior art is inconvenient to maintain. Since the internal space of the cabinet is relatively limited, the maintenance space for the internal electrical devices of the cabinet is narrow, which in turn causes inconvenience in maintenance.

[0005] 2. The modular high-voltage cabinet in the prior art is not easy to dry and dehumidify. When the ventilation slots are used for heat dissipation, it is not easy to dry and dehumidify the incoming air, which may cause excessive accumulation of moisture inside the cabinet, resulting in damage to the internal electrical components and reducing their service life.

[0006] 3. The existing high-voltage cabinets not only have low working and installation efficiency, but also low factory production capacity. Utility Model Content

[0007] The purpose of the utility model is to solve the above deficiencies in the prior art and to provide a high-voltage cabinet with a modular design.

[0008] A high-voltage cabinet with modular design comprises a high-voltage cabinet body, wherein the high-voltage cabinet body is composed of a low-voltage module, a vacuum circuit breaker module, a busbar room cable room module, and an arc self-extinguishing device which are movably connected.

[0009] The vacuum circuit breaker module comprises a vacuum circuit breaker module, a valve module, a grounding switch module, an interlocking module, and a control line incoming module. The module design and placement are reasonable, meeting the use requirements of the high-voltage cabinet and greatly reducing the volume of the high-voltage cabinet.

[0010] The busbar room and cable room module includes a busbar, a wall bushing, a contact box, a current transformer, and a lightning arrester. The installation structure is diverse, which meets the needs of multi-functional use and improves practicality.

[0011] The low-voltage module comprises a switch cabinet upper door panel and a mounting plate portion, and is convenient for maintenance, installation and replacement.

[0012] The low voltage module, vacuum circuit breaker module and busbar room cable room module are all locked and fixed by multiple flange bolts, with simple structure and convenient splicing. They can be replaced individually according to the needs of each module and are easy to adjust.

[0013] As a further improvement, the outer side walls of the high-voltage cabinet body are equipped with multiple push handles. The provision of the push handles can effectively facilitate the staff to move and install each module, facilitate disassembly, and improve work efficiency.

[0014] As a further improvement, the main body of the high-voltage cabinet is made of metal material, and the metal material adopts a double-layer design. The outer layer is made of aluminum-zinc plate, and the inner layer is made of fiberglass. Fiberglass is a composite material composed of glass fiber and resin. Its main characteristics are light weight, high strength and good insulation performance. The use of fiberglass can effectively improve the strength of the product and the electrical safety distance.

[0015] As a further improvement, the side walls of the low-voltage module, vacuum circuit breaker module, and busbar room cable room module are provided with heat dissipation openings, and a moisture-proof layer is installed inside the heat dissipation opening. The moisture-proof layer includes two layers of dustproof nets, and moisture-proof dry bags are clamped and filled between the dustproof nets, which can effectively prevent them from getting damp during heat dissipation and prevent moisture accumulation inside them from causing damage to power components. Since they are dried using moisture-proof dry bags, they are easy to replace, which has a dehumidification effect. One side of the dustproof net is hinged to the inner side wall of the open opening, and the hinge method is spring hinge, which is convenient to switch.

[0016] Beneficial effects:

[0017] The device locks and fixes the low-voltage module, vacuum circuit breaker module, and busbar room cable chamber module through multiple flange bolts. The device has a simple structure and is easy to splice. It can be replaced individually according to the needs of each module, and is easy to adjust. It can be used with a push handle, which is convenient to operate, simple to maintain, and convenient to install and use in various spaces. It can effectively prevent it from falling during transportation, improve its work efficiency and safety, expand the factory's production capacity, and ensure its safety during transportation. Each component is locked and fixed with flange bolts and has good interchangeability, which improves work efficiency. The high-voltage switchgear with modular structure design does not interfere with each other during production, which greatly improves work and production efficiency, solves the shortcomings of the existing high-voltage cabinet that not only has low work and installation efficiency, but also has low factory production capacity. At the same time, it solves the problem that its maintenance space is narrow, which will cause inconvenience in maintenance. The low-voltage module, vacuum circuit breaker module, and busbar room cable chamber module are locked and fixed through multiple flange bolts. The device has a simple structure and is easy to splice. It can be replaced individually according to the needs of each module, and is easy to adjust. It can be used with a push handle, which is convenient to operate, simple to maintain, and convenient to install and use in various spaces.

[0018] The device is provided with a moisture-proof layer, which can effectively prevent it from getting damp during heat dissipation and prevent moisture accumulation inside it from causing damage to power components. Since it uses a moisture-proof drying bag for drying, it is easy to replace, so that it has a dehumidification effect. One side of the dustproof net is hinged to the inner side wall of the spread opening, and the hinge method is spring hinge, which is convenient to switch. The modular high-voltage cabinet in the prior art is not convenient for drying and dehumidification. When the ventilation slots are used for heat dissipation, it is inconvenient to dry and dehumidify the incoming air, which may cause excessive accumulation of moisture inside the cabinet, resulting in damage to the internal power components and reducing its service life.

[0019] The device is equipped with an arc self-extinguishing device. When arcing occurs in the cabinet, the arc can be extinguished in the self-extinguishing device to prevent the arc from damaging the cabinet and causing personal injury to the operator. BRIEF DESCRIPTION OF THE DRAWINGS
