Alarming device for falsely opening electrified space cabinet door

Abstract

The invention discloses an alarming device for falsely opening an electrified space cabinet door, comprising a power source and a stroke switch arranged on a cabinet door. A normally-opened contact of the stroke switch is connected with a voice alarming device, the other side of the stroke switch is connected in series with a contact of an electroscope, and the power source is arranged between the voice alarming device and the contact of the electroscope. The invention judges whether the cabinet is electrified by utilizing the contact of the electroscope, the normally-opened contact of the stroke switch is closed when the cabinet door is opened when equipment is electrified, a circuit is switched on, and an alarm sends a voice signal to alert a client that the equipment is electrified so as to stop operation. No any prompting is changed to voice alarming, thereby the reliability of protecting people who violate regulations to falsely enter the electrified space is greatly increased, the safety and the efficiency of construction are increased and the security is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, in particular to an alarm device for accidentally opening a charged partition cabinet door. Background technique [0002] At present, electric energy, as a necessity of life, has been popularized in all aspects of people's life. At the same time, electric energy is a kind of high-risk energy, and operation management must have professional skills. In order to prevent personal electric shock casualties, a large number of live parts of electrical equipment are isolated and sealed with metal cabinets to prevent people and other objects from entering and causing personal or equipment injury. As a high-risk energy source, electricity has no characteristics and cannot be seen or heard. When the door of the live equipment cabinet is opened, personnel without professional knowledge may be in danger of electric shock at any time without any warning. Especially the high and low voltage electri...
