Description

Technical Field

[0001] The utility model relates to the field of low-voltage cabinets, in particular to a low-voltage cabinet live protection device with high safety. Background Art

[0002] The switch cabinet is an electrical equipment. The external line of the switch cabinet first enters the main control switch in the cabinet, and then enters the branch control switch. Each branch is set according to its needs. The components in the switch cabinet mainly include circuit breakers, disconnectors, load switches, operating mechanisms, mutual inductors and various protective devices. The low-voltage switch cabinet is a type of switch cabinet. The low-voltage switch cabinet is suitable for power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries for power transmission, distribution and power conversion. In the prior art, a Chinese patent document with application number CN202222926146.1 records a live protection device for low-voltage cabinets in power engineering. The patent sets a low-voltage cabinet body, a power-on detection control device, electrical components, an insulating cover, a lock sleeve, an electromagnet, a guide strip, an elastic part, a lock head and a control rod. The insulating cover can isolate the electrical components to prevent the staff from electric shock during the maintenance process. At the same time, when the low-voltage cabinet body is energized, it can be detected by the power-on detection control device and control the electromagnet to be energized, and the electromagnet is energized to generate The magnetically attracted lock extends out of the guide hole into the lock sleeve, thereby locking the insulating cover. The staff needs to manually pull the control lever to drive the lock to move out of the lock sleeve before unlocking the insulating cover, thereby reminding the staff to prepare in advance, thereby effectively reducing the probability of electric shock to the staff during maintenance. When the existing low-voltage cabinet live protection device for power engineering is in use, when the staff performs maintenance without knowing it, the current can easily pass through the human body to reach the ground to form a path, which has no protective effect and is prone to cause safety accidents. In addition, the power cord connection at the rear end of the cabinet is easily loosened by external tension, causing a short circuit, affecting the connection, and having low safety, which has brought certain adverse effects on people's use process. For this reason, we propose a high-safety low-voltage cabinet live protection device. Utility Model Content
