Rear cabinet door positioning device for switch cabinet

Abstract

The invention discloses a rear cabinet door positioning device for a switch cabinet. The rear cabinet door positioning device includes a moving trolley, a fixing mechanism and a lifting driving mechanism, a supporting assembly is arranged on the moving trolley, the fixing mechanism includes a fixing frame and a connecting piece for detachably connecting with the rear cabinet door of the switch cabinet, the connecting piece is arranged on the fixing frame, and the fixing frame can be arranged on the supporting assembly in a lifting mode through a sliding guiding mechanism; and the lifting driving mechanism is arranged on the supporting assembly and connected with the fixing frame to drive the fixing mechanism to ascend or descend. According to the rear cabinet door positioning device for the switch cabinet, carrying and fixing the rear cabinet door of the switch cabinet of operation and maintenance personnel can be replaced in the assembly and disassembly processes of the rear cabinet door of the switch cabinet, thus the risk that the operation and maintenance personnel lacks of physical strength and is injured possibility due to the high height and weight of the rear cabinet door when disassembling and assembling the rear cabinet door of the switch cabinet is avoided, and personal safety of the operation and maintenance personnel is guaranteed.

Description

technical field [0001] The invention relates to a positioning device for a rear cabinet door of a switch cabinet. Background technique [0002] The switchgear in the substation is high-voltage electrical equipment, and 10kV or 35kV busbars, lightning arresters, voltage transformers, station transformers, grounding transformers, feeder circuit breakers, and handcart knife switches and other high-voltage equipment are installed in the cabinets. According to the design requirements that the insulation of high-voltage electrical equipment must ensure sufficient safety distance, the conventional size of the 10kV switchgear is 2200 mm high and 800 mm wide. [0003] The switching operation of substation equipment is one of the most important tasks of substation operation and maintenance personnel, and it is very difficult to remove and install the rear cabinet door of the switch cabinet. Operation and maintenance personnel carry out busbar and PT maintenance, feeder switch circuit...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of this working method are: (1) the back door of the switchgear is high and heavy, and it is difficult for operation and maintenance personnel with small stature and strength to assemble, disassemble and carry, and there are hidden dangers to personal safety; (2) ) The rear cabinet door bolts of the switchgear have a small hole diameter and require high precision for disassembly and assembly operations

In the absence of auxiliary tools, it is difficult and time-consuming to disassemble the door of the switchgear. At the same time, there is a risk of personal injury, which reduces the timeliness of power transmission.
