Description

Technical Field

[0001] The utility model relates to the technical field of high and low voltage switch cabinets, in particular to a high and low voltage switch cabinet with a remote monitoring function for electrical automation engineering. Background Art

[0002] High and low voltage switchgear is an electrical device used to connect high or low voltage cables. It is usually used in power supply bureaus and substations. It receives high voltage power through the high voltage switchgear, and after the voltage is reduced by the transformer, it is sent to the low voltage switchgear, and then distributed to the distribution boxes of various power users.

[0003] For example, the Chinese utility model provides a "high and low voltage switchgear with anti-static function for electrical automation engineering" patent number: 202221258191.8. This patent includes a main cabinet body, the inner inner wall of which is provided with a control mechanism, and the control mechanism includes a fixed frame movably provided on the inner inner wall of the main cabinet body. By pushing the pull ring, the limiting plate slides along the control rod while the limiting plate compresses the spring, and then pulling the pull ring, the limiting plate drives the spring to rotate, so that the movable block rotates on the inner side of the fixed frame with the movable axis as the axis, so as to facilitate the replacement of the mounting frame and the ground wire, thereby facilitating the conduction of static electricity.

[0004] Although the above document solves the problem that traditional high and low voltage switch cabinets generate static electricity when workers open the door panels, and static electricity will cause certain damage to the equipment inside the high and low voltage switch cabinets, it still has the disadvantage of not having a heat dissipation function. The internal equipment of the high and low voltage switch cabinets will generate high temperature during operation or when a fault occurs. Failure to dissipate heat in time will affect the service life of the equipment and may even cause a fire. For this reason, a high and low voltage switch cabinet with remote monitoring function for electrical automation engineering is introduced here. Utility Model Content
