Problems solved by technology
The distance between the terminal and the cabinet of the switch cabinet can meet the insulation requirements of the cables in operation, but in the withstand voltage test, the test voltage is much higher than the operating voltage, and the insulation distance between the terminal and the cabinet is difficult to meet the insulation requirements. Therefore, it is necessary to add a layer of insulating medium between the terminal and the cabinet to meet the insulation requirements during the test
[0003] At present, the general practice of adding a layer of insulating medium to meet the insulation requirements during the test is to design the insulating sheath according to the size of the switchgear terminal to ensure that the insulating sheath can be tightly attached to the terminal, but the insulation device designed according to the specific size cannot be applied Compared with switch cabinets of other sizes, the universality is not high

The invention relates to a switch cabinet. The switch cabinet comprises a cabinet body and an insulation assembly, and the insulation assembly can be arranged on the cabinet body. The insulation assembly comprises at least two insulation sheets, and every two adjacent insulation sheets are arranged on the cabinet body side by side. Each insulation sheet comprises an insulation part and an adsorption part, wherein the insulation part is arranged on the switch cabinet body, the adsorption part is arranged on the part, close to the cabinet body, of the insulation part and can apply acting force towards the cabinet body to the insulation part, the adsorption part can enable the insulation part to be tightly attached to the cabinet body, and the insulation part can improve the insulation performance of the cabinet body. The number of the insulation assemblies can be adjusted according to test requirements and the size of the switch cabinet, so that the insulation assemblies can be suitable for switch cabinets of different sizes, and the application range and the universality of the insulation assemblies are widened.
Description
technical field [0001] The invention relates to the technical field of electric equipment, in particular to a switch cabinet, an insulating component and an insulating sheet. Background technique [0002] The preventive test of switchgear is an important measure to ensure the safe operation of electrical equipment. Its purpose is to check whether the switchgear is in good condition during long-term operation, and to grasp the insulation of the switchgear, so as to detect defects or faults in time and ensure the safety of the switchgear. Safe to use. The distance between the terminal and the cabinet of the switch cabinet can meet the insulation requirements of the cables in operation, but in the withstand voltage test, the test voltage is much higher than the operating voltage, and the insulation distance between the terminal and the cabinet is difficult to meet the insulation requirements. Therefore, it is necessary to add a layer of insulating medium between the terminal a...
