A disconnection automatic detection and isolation alarm power distribution cabinet device and its use method

Abstract

The invention relates to a power distribution cabinet device for automatic detection, isolation and alarming for a broken wire, which comprises a box body. Alarming lights which are distributed in anarray are arranged outside the upper half part of the box body; and the left half part and the right half part inside the box body are provided with a first isolation plate and a second isolation plate fixedly connected to the front inner wall and the rear inner wall of the box body. The device disclosed in the invention has the beneficial effects that the structure is simple; the operation is simple and convenient; when a wire of an electrical component of the power distribution cabinet box is broken, an electromagnet loses an adsorption force for a first iron block, a sliding plate falls, asecond iron block at the top of the sliding plate is separated from a connection contact 4 during the falling process, the alarming light is on, the bottom two ends of the sliding plate later press button controllers 4, a wire dragged at the bottom part of the box body is isolated, generation of step voltage is prevented, a third controller is started when a third iron block at the bottom center of the sliding plate is contacted with a second connection contact to timely alarm a power company, and economic losses are reduced.

Description

Technical field [0001] The invention relates to the technical field of outdoor power distribution cabinet failure processing, and in particular to a disconnection automatic detection and isolation alarm power distribution cabinet device and a use method. Background technique [0002] At present, outdoor power distribution cabinet is a complete set of switchgear and control equipment. As a power center and main power distribution device, it is mainly used to control, monitor, measure and protect power lines and main electrical equipment. Electrical components rely on wires for circuit control, but the connection wire will inevitably be broken during use. When the wire is broken and dragged to the bottom of the inner wall of the power distribution cabinet, it will cause a step voltage on the ground around the power distribution cabinet, and When a wire breaks, people often have to wait until economic losses occur before it can be found and repaired. There is no existing method that...

[0002] At present, the outdoor power distribution cabinet is a complete set of switchgear and control equipment. As a power center and main power distribution device, it is mainly used for the control, monitoring, measurement and protection of power lines and main electrical equipment. Electrical components rely on wires for circuit control, but it is inevitable that the connecting wires will be broken during use. When the broken wires are dragged on the bottom of the inner wall of the power distribution cabinet, it will cause a step voltage to the ground around the power distribution cabinet, and When the wire is broken, it is often not discovered until the economic loss is generated, so as to carry out maintenance. There is currently a lack of a method that can automatically detect the wire breakage of the electrical components in the power distribution cabinet in real time and alarm at the first time and remove the broken wire from the box. Power distribution cabinet isolated from the bottom of the inner wall
