Problems solved by technology

In some southern regions, due to the abundance of groundwater, the ground rods are easily corroded when they are installed in the underground soil for a long time
When the grounding rod is corroded, there will be a gap between the grounding rod and the underground soil layer, resulting in the switchgear not being reliably grounded

Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0012] See figure 1 , a switchgear, comprising a cabinet body 1, the cabinet body 1 is installed on the ground 100, the outer wall of the lower end of the cabinet body 1 is densely covered with needles 3 extending along the periphery of the cabinet body 1. The acupuncture 3 is a cylinder with a diameter of 1 mm and a length of 3 cm.

[0013] The outer side of the acupuncture 3 is provided with a guard plate 9, and the guard plate 9 is connected to a cylinder rod 70 of a cylinder 7, and the cylinder 7 is installed on the outer wall of the cabinet body 1 through a bracket 5.

[0014] 16 infrared sensors 11 are also arranged on the outer wall of the cabinet body 1, and these 16 infrared sensors 11 are respectively located on the front side wall, rear side wall, left side wall and right side wall of the cabinet body.

[0015] And the distance be...

Abstract

The invention discloses a switch cabinet which comprises a cabinet body and is characterized in that an installation support frame is arranged below the cabinet body. Guide pillars are arranged on four corners of the installation support frame. Ground rods are sleeved on the guide pillars and cone-shaped. Cone-shaped small ends of the ground rods face downwards. Elastic components are arranged between the upper end faces of the ground rods and the lower end face of the installation support frame. The upper ends of the elastic components are abutted against the lower end face of the installation support frame. The other ends of the elastic components are abutted against the upper end faces of the ground rods. As the ground rods are forced to face downwards by the elastic components, when the ground rods are corroded, the ground rods can still be tightly adhered to the underground soil layer. Thus, when being used in southern places where underground water is rich, the switch cabinet can reliably keep connected with the ground.

Description

technical field [0001] The invention relates to a switch cabinet. . Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instrumentation, automatic control, motor magnetic switch, various AC contactors, etc., and some also have high-voltage room and low-voltage room switchgear, such as power plants. [0003] For reliable grounding, the switchgear is also provided with grounding rods. In some southern regions, due to the abundance of groundwater, the ground rods are easily corroded when they are installed in the underground soil for a long time. When the grounding rod is corroded, there will be a gap between the grounding rod and the underground soil layer, resulting in the unreliable grounding of the switchgear. . Contents of the invention [0004] The purpose of the present inve...
