Description

Technical Field

[0001] The utility model relates to the technical field of isolating switches of environmental protection cabinets, in particular to an isolating switch group on an environmental protection cabinet. Background Art

[0002] The environmental protection cabinet is an electrical device that consists of a set of high-voltage switchgear installed in a steel metal cabinet or made into an assembled interval ring network power supply unit. Its core parts use load switches and circuit breakers. Due to its simple structure, small size, low price, and the ability to improve power supply parameters and performance as well as power supply safety, it is widely used in load center distribution stations and box-type substations in urban residential areas, high-rise buildings, large public buildings, factories and enterprises.

[0003] The environmental protection cabinet includes an upper isolating switch, which has multiple isolating contacts. In the prior art, only one protective cover is provided outside the multiple isolating contacts. This results in the need to remove the entire protective cover when repairing the isolating contacts. Moreover, the disassembly process is very troublesome due to the large size of the protective cover, and only one protective cover cannot ensure the insulation between adjacent isolating contacts.

[0004] After searching, the Chinese patent publication number CN217822446U discloses an isolating switch group on an environmental protection cabinet with a three-phase discrete insulating shield. The isolating switch group can overcome the defect in the prior art that the shield needs to be removed as a whole when disassembling, and independent maintenance cannot be achieved. However, there are still certain disadvantages when using it. In this device, an insulating shield is covered on the outside of the isolating contact, and the insulating shield is installed on the top support rod and the side support rod by the cooperation of the first extension plate and the second extension plate with the fastening nails. The use of fastening nails for fixed connection makes it more troublesome to disassemble and assemble the insulating shield, which affects the work efficiency during maintenance and is not practical enough. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an isolating switch group on an environmental protection cabinet that can make the disassembly and assembly of the insulating shield more convenient, effectively improve the work efficiency during maintenance, and improve practicality.

[0008] Preferably, the top ends of the two groups of pull plates are fixedly connected with pull rings.

[0009] Preferably, a fastening sleeve is fixedly provided in the insertion holes on the four groups of support plates.

[0010] Preferably, the outer sides of the four groups of pinching pieces are all provided with anti-slip grooves.

[0011] Preferably, the outer edges of the four groups of insertion rods are all chamfered.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: during installation, the pinching piece is pinched by hand to drive the slide plate to slide inward, the tensioning spring is compressed, and the connecting plates on both sides of the insulating shield are placed on the top support rod and the side support rod, so that the connecting plates are between the two sets of support plates, and the installation of the support plates on the top support rod is consistent with the installation on the side support rod, so that the insertion rod is aligned with the insertion hole, and then the pinching piece is released, so that the insertion rod is inserted into the insertion hole of the support plate under the action of the pinching piece rebounding, at this time the insertion rod is blocked by the limit latch, and then the pull plate is pulled to slide upward, the reset spring is compressed, so that the pull plate drives the limit latch to move upward, so that the limit latch no longer blocks the insertion rod, and the insertion rod continues to move under the tensioning spring. The spring will slide outwards along the socket under the action of the spring, and eventually the outer side of the rubber sleeve will rest against the support plate. At this time, the pin hole on the plug rod is aligned with the limit pin. By loosening the pull plate, the limit pin is inserted into the pin hole of the plug rod under the action of the reset spring, thereby restricting the plug rod to prevent the tightening spring from being accidentally compressed and causing the plug rod to be separated from the socket, thereby completing the installation of the insulating cover. When maintenance and disassembly are required, it is only necessary to pull out the limit pin from the pin hole of the plug rod, and then press the pinching piece to disengage the plug rod from the socket of the support plate, and then the insulating cover can be removed from the top support rod and the side support rod, so that the disassembly and assembly of the insulating cover can be more convenient, which effectively improves the work efficiency during maintenance and improves practicality.
