Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a complete set of switch equipment. Background Art

[0002] A complete set of switchgear refers to a collection of equipment used to control, protect and monitor electrical equipment and circuits in an electrical system, also known as a switch cabinet. These devices usually include circuit breakers, disconnectors, contactors, relays, protection devices, instruments and control switches. A complete set of switchgear can be customized and combined according to specific application requirements to meet the electrical control and protection requirements of various places. There are several wires connecting the equipment, there are many internal lines in the switch cabinet, and there are many buttons and fixing screws on the equipment.

[0003] The Chinese patent discloses a switch cabinet and switch cabinet authorization announcement number CN209929839U), the patented technology includes a switch cabinet, the switch cabinet includes a busbar room and a top cover extending forward and backward at the top of the switch cabinet, a three-phase busbar is arranged in the busbar room, the three-phase busbar is correspondingly connected to a three-phase busbar, the top cover is provided with a bushing for the three-phase busbar to pass through, and the three-phase busbar is arranged in a "pin" shape so that a corresponding air insulation distance is formed between any two adjacent phase busbars. When the switch cabinet of the utility model is a KYN28A-12 switch cabinet with a width of 800mm, when transmitting a current of 4000A, the specification of the three-phase busbar is 125mm*10mm. Since the three-phase busbar is arranged in a "pin" shape structure, the minimum width of the switch cabinet required when two busbars in one row meet the minimum air insulation distance (i.e. 125mm) is 625mm, so the KYN28A-12 switch cabinet with a width of 800mm meets the air insulation distance when transmitting a current of 4000A. Moreover, when transmitting the same large current, compared with the existing switch cabinet, the switch cabinet of the utility model has a narrower width and a more compact structure.

[0004] This patented technology has a more compact structure when in use, but it still has some shortcomings when in use. The compact structure between the devices causes the lines to be squeezed together, there are many buttons and labels on the devices, and the font is small and not easy to observe. When the equipment is damaged and maintained, targeted repairs are required for the equipment model. The connections between the devices, the installation screws and the text introductions are dazzling, which can easily lead to operational errors by the installers during the maintenance process. Therefore, the technical personnel in this field provide a complete set of switch equipment to solve the problems raised in the above background technology. Utility Model Content

The second plug block 211 is plugged into the second plug hole 209. The second plug holes 209 are horizontally equidistantly distributed on the outer wall of the transverse guide rod 202.

[0045] Performing use of the amplification structure 200;

[0046] When the switchgear 100, including the circuit breaker, disconnector, contactor, relay, protection device, instrument and other complete switchgear, needs maintenance, the transverse guide rod 202 is grasped and longitudinal force is applied.

[0047] Example 2

[0048] See also Figure 1-Figure 5 As shown, this embodiment is based on the embodiment 1 and also includes:

[0049] as well as;

[0050] The mobile structure 300 includes a bottom frame 301, a mounting frame 302 located at the lower end of the switch cabinet 100 and inside the switch cabinet 100, compression springs 304 located at the four corners of the upper end of the mounting frame 302, pulleys 303 located at the four corners of the lower end of the mounting frame 302, a force block 305 located at the upper end of the mounting frame 302, a hydraulic rod 307 located on the inner wall of the rear side of the bottom frame 301, and a travel block 306 located at the telescopic end of the hydraulic rod 307.
