Description

Technical Field

[0001] The utility model relates to an electrical device, in particular to a visual AC closed switch cabinet. Background Art

[0002] AC enclosed switchgear, or switchgear, refers to switchgear and control equipment in the power system that is completely enclosed by the enclosure except for the incoming and outgoing lines. Switchgear and control equipment refer to the combination of switchgear and its related control, measurement, protection and regulation equipment, as well as the general term for the assembly of these devices and equipment with related electrical connections, accessories, enclosures and support parts. Switchgear is widely used in power generation, transmission and distribution stations at all levels, as well as distribution stations and box-type substations in urban residential areas, large public buildings, factories and enterprises and other load centers.

[0003] At present, most switch cabinet products need to rely on the switch cabinet status indicator to judge the switch operation status during use, or use a built-in camera to display the switch operation status. However, the status indicator cannot directly display the actual status of the switch. Once the status indicator fails, it cannot accurately indicate the actual operation status of the switch. The use of a built-in camera requires the installation of related devices such as video, transmission, and communication, which has problems such as high cost, easy damage, unreliable performance, and inability to maintain when running under power. Utility Model Content

The contactor operating mechanism and the contactor body are both connected to the gas box body, the contactor operating mechanism is located outside the gas box body, and the contactor body is located inside the gas box body. The transmission device is connected between the contactor operating mechanism and the contactor body, and the contactor operating mechanism controls the contactor body to move through the transmission device.

[0008] Furthermore, sealing members are provided between the outer panel and the frame, and between the inner partition and the frame, and the sealing members are made of transparent material.

[0009] Furthermore, the transparent, insulating material is polymethyl methacrylate, polycarbonate, polyethylene terephthalate, polypropylene, polyvinyl chloride, ABS, thermoplastic polyurethane elastomer rubber, polystyrene, polysulfone or transparent nylon.

[0010] Furthermore, the outer panel, the frame and the inner partition are all made by injection molding.

[0011] Compared with the prior art, the visualized AC closed switch cabinet of the utility model has at least the following beneficial effects:

[0012] The utility model provides a visualized AC closed switch cabinet.

The outer panel, the frame, and the inner partition are all made of transparent and insulating materials. The outer panel is connected to the outer side of the frame, and the outer panel forms a closed cavity. The inner partition is connected to the inner side of the frame. The inner partition divides the closed cavity into four independent spaces. The four independent spaces are a base 21, a switch room 22, a mechanism room 23, and an electric control box 24. The base 21 is located at the bottom, and the base 21 is a structural support for the entire cabinet body. The front of the base 21 provides a space for installing cables. The switch room 22 and the mechanism room 23 are both located at the base 21. Above, the mechanism room 23 is located on the front side of the cabinet, and the switch room 22 is located on the rear side of the cabinet. The switch room 22 provides installation space for high-voltage switch elements. The switch room 22 can be a sealed gas box structure that is not affected by the external environment, or it can be a non-sealed box or other structure. The mechanism room 23 provides installation, maintenance, and operation space for the operating mechanism of the high-voltage switch. The electric control box 24 is located above the mechanism room 23.
