Problems solved by technology

[0002] Box-type substations are often installed on roads, residential areas, and around squares. Fences are often used around box-type substations to prevent outsiders from entering. The fences are easily damaged and box-type substations are unattended. Often, fence damage cannot be found, and people or animals It is easy to get close to danger, and because the outdoor grounding grid often fails to meet the requirements of the grounding grid due to corrosion, it affects the safe operation of the substation
Chinese patent CN202662111U discloses a "box-type substation voice alarm device". The use of infrared alarm system preliminarily solves the problem that when someone enters the protection area, the system can voice alarm to prompt irrelevant personnel to leave, but the corrosion of the outdoor grounding grid affects the safe operation of the substation. call the police in time

Abstract

The invention discloses a box type transformer substation with an alarm device, and belongs to power transformation equipment. Particularly, the box type transformer substation with the alarm device has a safety pre-warning expelling function and a ground resistance off-limit alarm function. The box type transformer substation with the alarm device comprises a box type transformer substation body, and is characterized in that a voice pre-warning safety device and a ground resistance off-limit alarm device are installed on an outer shell of the box type transformer substation body. The box type transformer substation with the alarm device has the advantages that the intelligent induction pre-warning device is installed on the outer shell of the box type transformer substation, so that people or animals close to the box type transformer substation are effectively reminded to be far away from high-voltage risks, and safety accidents are prevented; the ground resistance off-limit alarm device can remind professionals of ground connection conditions of the outer shell of electrified equipment and prevents people and the equipment from risks.

Description

technical field [0001] The invention belongs to substation equipment, in particular to a box-type substation with a safety pre-warning drive-away function and a grounding resistance over-the-line alarm function. Background technique [0002] Box-type substations are often installed on roads, residential areas, and around squares. Fences are often used around box-type substations to prevent outsiders from entering. The fences are easily damaged and box-type substations are unattended. Often, fence damage cannot be found, and people or animals It is easy to get close to danger. In addition, the outdoor grounding grid often fails to meet the requirements of the grounding grid due to corrosion, which affects the safe operation of the substation. Chinese patent CN202662111U discloses a "box-type substation voice alarm device". The use of infrared alarm system preliminarily solves the problem that when someone enters the protection area, the system can voice alarm to prompt irrele...
