AI Technical Summary
The existing pre-installed substations may cause electric shock accidents due to lack of insulation protection devices during leakage. Especially in crowded areas, the reduced sensitivity of the leakage protector will lead to a long leakage duration, increasing the risk of electric shock accidents.
A pre-installed power leakage warning device for substation renovation is designed, including an insulated base, a substation cabinet and a top slot, equipped with an insulated protective rod and an insulated warning belt. When leakage occurs, the motor drives the threaded shaft to drive the rectangular frame and the insulation warning. The belt moves downwards to separate the substation cabinet from the crowd to prevent electric shock.
It effectively prevents contact between the substation and the crowd, reduces the occurrence of electric shock accidents, ensures the safety of personnel, and can even isolate the substation cabinet in time when the sensitivity of the leakage protector is reduced to prevent electric shock.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of leakage warning, in particular to a leakage warning device for pre-installed substation reconstruction. Background Art
[0002] A substation refers to a place in the power system where voltage and current are transformed, electric energy is received and distributed. A prefabricated substation is also called a box-type substation. Prefabricated substations are suitable for residential areas, urban public substations, busy downtown areas, construction power supplies and other places. Therefore, the safety and stability of substations have always been the focus of attention.
[0003] Existing prefabricated substations may cause leakage due to internal moisture or excessive dust. The existing substation leakage warning device can give timely warnings and send leakage information to maintenance personnel when working. However, it takes some time for maintenance personnel to rush to repair after receiving the signal. Since prefabricated substations may be distributed in crowded places, the substations have no insulation protection devices and cannot separate the substations from the crowd in time. When leakage occurs, although it is protected by the leakage protector, as the sensitivity of the leakage protector decreases, electric shock accidents may occur if the leakage lasts for a long time.
[0004] Therefore, we make improvements to this and propose a leakage warning device for prefabricated substation reconstruction. Utility Model Content
