Abstract

The invention provides a special earthing trolley for integration of armored mid-set high-voltage switch cabinet electricity testing and earthing and a using method thereof. The special earthing trolley comprises an electricity testing device, a conductive rod, a moving contact, an upper earthing knife contact, an earthing wire, a bottom plate, a plurality of wheels, a trolley insulation panel, apush-pull insulation handle, an earthing knife with a control handle and an earthing wire hand driving device, wherein the trolley insulation panel is vertically arranged on the bottom plate; the lower end of the bottom plate is provided with the trolley insulation panel; the conductive rod is inserted in the trolley insulation panel and is arranged in parallel with the bottom plate; the earthingknife with a control handle and the earthing wire hand driving device are arranged on the trolley insulation panel; and the moving contact and the upper earthing knife contact are arranged on the conductive rod. The maintenance and operation work can be greatly facilitated, and the personal safety of personnel is ensured.

Description

technical field [0001] The present application relates to the field of electrical inspection and detection of electric power systems, in particular to a special earthing trolley for the integration of electrical inspection and grounding of armored middle-mounted high-voltage switchgear and its use method. Background technique [0002] In the 10 kV power system, there are two main types of air-insulated switchgear, one is armored middle-mounted high-voltage switchgear such as KYN28 type, and the other is fixed cabinet such as XGN type. At present, KYN28 type switchgear has been gradually used in power equipment It is planned to replace the XGN switchgear within 3 years. That is to say, the central switchgear has gradually become the mainstream equipment of the 10 kV power system in substations and switching stations. [0003] However, when this type of switchgear is overhauling the busbar, according to safety technical measures, it is necessary to carry out power failure, pow...
