Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, and in particular to a GGD type AC low-voltage power distribution fixed switchgear. Background Technology

[0002] The GGD type switchgear adopts a fixed installation structure. The cabinet is made of high-quality cold-rolled steel plate, which has high strength. The internal components adopt a modular design, which is convenient for expansion and replacement. The GGD type AC low-voltage distribution fixed switchgear is a low-voltage power distribution equipment widely used in power systems. It is mainly used in power plants, substations, industrial and mining enterprises and other places as a device for power distribution, control, protection and monitoring. It is suitable for AC 50Hz power distribution systems with a rated operating voltage of no more than 380V and a rated current of no more than 3150A.

[0003] Chinese patent discloses a GGD type AC low-voltage fixed switchgear (authorization announcement number CN214044467U). This patented technology includes a switchgear body, a heat dissipation groove and a level on one side of the switchgear body, a top cover at the upper end of the switchgear body, and locking parts at both ends of the top cover for fixing the switchgear body. The switchgear body is composed of a first distribution cabinet, a second distribution cabinet and a third distribution cabinet. The top cover connects the first distribution cabinet, the second distribution cabinet and the third distribution cabinet. The top cover is equipped with a first cooler, a second cooler and a third cooler. The first cooler, the second cooler and the third cooler are all equipped with cooling air vents. The cooling air vents pass through the first distribution cabinet, the second distribution cabinet and the third distribution cabinet respectively. The first distribution cabinet, the second distribution cabinet and the third distribution cabinet are all equipped with heating mechanisms and triangular mounting brackets. This utility model is suitable for high temperature and low temperature environments and has the advantages of heating and rapid cooling.

[0004] While this patented technology facilitates temperature adjustment during use, it still has shortcomings. The GGD type AC low-voltage fixed switchgear is divided into multiple spaces such as a busbar compartment, a circuit breaker compartment, and a cable compartment. During use, the internal spaces are separated by partitions, resulting in a fixed internal space. When installing additional electrical equipment, the internal space is not easy to adjust, and the flexibility of use is insufficient. Therefore, those skilled in the art have provided a GGD type AC low-voltage fixed switchgear to solve the problems mentioned in the background art. Utility Model Content

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0040] Example 1

[0041] Please see Figures 1-5 As shown, this embodiment is a GGD type AC low-voltage power distribution fixed switchgear, including a cabinet 100.

[0042] The adjustment structure 200 includes multiple partitions 201 located inside the cabinet 100, guide rails 204 fixed to the inner walls of the upper and lower ends of the cabinet 100 and symmetrically distributed, mating grooves 203 opened inside the upper and lower ends of the partitions 201 and sleeved on the outside of the guide rails 204, a positioning plate 207 fixed inside the rear end of the cabinet 100, positioning holes 208 opened inside the positioning plate 207 and equidistantly distributed, a side plate 209 fixed to one end of the partitions 201, a sliding sleeve 210 embedded and installed inside the side plate 209, and a positioning rod 211 slidably installed inside the sliding sleeve 210 and located inside the positioning hole 208.

[0043] Both ends of the cabinet 100 are provided with downward-sloping ventilation windows 101 with openings 102, the front end of the cabinet 100 is provided with an opening 102, and the front end of the cabinet 100 is rotatably installed with relatively distributed cabinet doors 103.

[0044] A limit ring 212 is provided at the front end of the positioning rod 211, a pull handle 213 is provided at the front end of the limit ring 212, and a spring 214 sleeved on the outside of the positioning rod 211 is provided between the limit ring 212 and the side plate 209.

[0045] The partition 201 has equidistantly distributed connecting slots 202 inside;

[0046] Use the adjustment structure 200;

[0047] The internal partition 201 of the adjustment structure 200 slides within the roller groove 205 via ball bearings 206. After moving to the designated position, the pull handle 213 is gripped, causing the limiting ring 212 to move, which in turn applies a pulling force to the spring 214. The spring 214 is stretched by the force, and the positioning rod 211 is pulled and moved accordingly. After the partition 201 is adjusted to the designated position, the pull handle 213 is released, and the spring 214 loses its holding force. The elastic force of the spring 214 pushes the limiting ring 212 to move, which in turn causes the positioning rod 211 to be inserted into the corresponding positioning hole 208, thus positioning the partition 201 and preventing the partition 201 from shaking randomly. This divides the interior of the cabinet 100 into multiple areas, and the space of different areas is adjustable, improving the flexibility of use.

[0048] Example 2

[0049] Please see Figures 1-5 As shown, this embodiment further includes elements beyond those in embodiment 1;

Mounting plates 303 are installed inside screw holes 302 with screws 307 and fixed to mounting wall 301, thereby fixing mounting plates 303 inside cabinet 100. The number and spacing of mounting plates 303 can be adjusted according to the needs of different electrical equipment and installation space. It is worth noting that the busbar compartment is used to install the main busbar, which is responsible for the transmission and distribution of electrical energy. The busbar uses copper or aluminum busbars to improve conductivity and is separated from other spaces to ensure safety. The busbar compartment is connected to the incoming and outgoing cabinets and is responsible for distributing electrical energy to each circuit.

It is connected to the circuit breaker compartment and busbar compartment to realize the monitoring and control of the power distribution system.

[0057] The GGD type AC low-voltage fixed switchgear adopts a fixed installation structure of 300mm. The cabinet body of 100mm is made of high-quality cold-rolled steel plate, which has high strength and can effectively prevent the intrusion of dust and foreign objects. The internal components adopt a modular design, which is convenient for expansion and replacement and can adapt to different power distribution needs.
