Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage ring network cabinet equipment, in particular to a high-stability high-voltage ring network cabinet. Background Art

[0002] The high-voltage ring network cabinet is designed to improve the reliability of power supply and enable users to obtain power from two directions. The power supply network is usually connected in a ring shape. This power supply method is referred to as ring network power supply. The ring network cabinet is an electrical device in which a group of high-voltage switchgear is installed in a steel plate metal ring network cabinet or is made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. It has the advantages of simple structure, small size, low price, and can improve power supply parameters and performance as well as power supply safety. Before using the high-voltage ring network cabinet, multiple high-voltage ring network cabinets are generally placed side by side on the top of the steel frame to prevent ground moisture from affecting the high-voltage ring network cabinet. However, the stability is not enough. It is easy to shift the cabinet body when it is hit during daily use.

[0003] Therefore, in recent years, by providing a limit track at the bottom of the ring main unit, the stability of the ring main unit can be improved, but it also brings inconvenience to the installation of the ring main unit. When it is necessary to add a cabinet to the cabinet group, the space in the middle of some cabinets is limited. During installation, the cabinet needs to be inserted into a smaller space, which is difficult to install and takes a lot of time. Utility Model Content

[0007] As a preferred solution of a high-stability high-voltage ring network cabinet described in the utility model, a slide groove is provided at the bottom of the movable seat, and the slide groove fits with the slide rail and is slidably connected with it. The movable seat is detached from the base by sliding the movable seat along the slide rail, which facilitates the addition of the ring network cabinet and its assembly into the cabinet group.

[0008] As a preferred solution of a high-stability high-voltage ring network cabinet described in the utility model, a pin hole corresponding to the plug is opened on the outside of the ring network cabinet, and the plug passes through the fixed seat and the movable seat respectively and is plugged into the corresponding pin hole. By inserting the plug into the pin hole, it is convenient to fix the ring network cabinet assembled on the base, thereby improving the stability of the cabinet.

[0009] As a preferred solution of a high-stability high-voltage ring network cabinet described in the utility model, a paddle is fixedly connected to one end of the top of the limit rod away from the movable seat, and a limit groove corresponding to the paddle is opened on the top of the fixed seat. By toggling the paddle in the limit groove, the limit rod can be driven to slide.

[0010] As a preferred solution of the high-stability high-voltage ring network cabinet described in the utility model, the limiting rod is correspondingly plugged into the limiting hole, so as to be inserted into the movable seat for fixing.

[0011] As a preferred solution of a high-stability high-voltage ring network cabinet described in the utility model, the top of the roller is connected to the bottom of the movable seat by a spring hinge, and a storage groove corresponding to the roller is provided at the bottom of the movable seat. When the movable seat is retracted into the base, the roller can compress the spring hinge and be stored in the storage groove. When the movable seat is separated from the base, it can automatically pop out and contact the ground to support the movable seat.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model realizes mutual cooperation among the base, the fixed base and the movable base, and provides a slidable movable base on the top of the base, which can be flexibly removed from the base range, making the installation of the ring network cabinet more convenient and easy, avoiding the insertion of the ring network cabinet in a small space, shortening the installation time of the ring network cabinet, and improving the assembly efficiency of installing the ring network cabinet into the cabinet group.

[0022] See also Figure 1-3 The utility model provides a high-stability high-voltage ring network cabinet, including a base 1, fixed seats 2 are arranged at both ends of the top of the base 1, a movable seat 3 is arranged near the middle of the top of the base 1, a slide rail 4 corresponding to the movable seat 3 is fixedly connected to the top of the base 1, a ring network cabinet body 6 is arranged on the top of the fixed seat 2 and the movable seat 3, and a slide groove 5 is opened at the bottom of the movable seat 3, the slide groove 5 is fitted with the slide rail 4 and is slidably connected with it, and the movable seat 3 is detached from the base 1 by sliding out along the slide rail 4, so that the ring network cabinet body 6 can be added and assembled into the cabinet group.

[0023] Pins 7 are provided on both sides of the outer walls of the fixed seat 2 and the movable seat 3, and pin holes corresponding to the pins 7 are opened on the outer side of the ring network cabinet 6. The pins 7 pass through the fixed seat 2 and the movable seat 3 respectively and are plugged into the corresponding pin holes. By inserting the pins 7 into the pin holes, the ring network cabinet 6 assembled on the base 1 is easily fixed, thereby improving the stability of the cabinet.

[0024] A limiting rod 8 is slidably connected inside the fixed seat 2, and a paddle 10 is fixedly connected to the top end of the limiting rod 8 away from the movable seat 3. A limiting groove 11 corresponding to the paddle 10 is opened on the top of the fixed seat 2. By paddle 10 is moved in the limiting groove 11, the limiting rod 8 can be driven to slide.

[0025] A limiting hole 9 corresponding to the limiting rod 8 is provided inside the movable seat 3 , and the limiting rod 8 is plugged into the limiting hole 9 correspondingly, so as to be inserted into the movable seat 3 and fixed thereon.

[0026] Rollers 12 are provided at the four corners of the bottom of the movable seat 3, wherein the top of the roller 12 is connected to the bottom of the movable seat 3 through a spring hinge, and a storage groove corresponding to the roller 12 is provided at the bottom of the movable seat 3.
